Design of Smart Actuators and Devices
Prof. Wei-Hsin Liao
The Chinese University of Hong Kong, Hong Kong
Abstract:
Innovation and application are two key elements for significant research and product development. Using
smart materials, we have designed various actuators and devices. For hard disk drives, we designed a
dual-stage servo system using enhanced active–passive hybrid piezoelectric actuators, which improve the
existing dual-stage actuators for higher precision and shock resistance, due to the incorporation of passive
damping in the design. For optical pickup devices, we also developed active-passive hybrid piezoelectric
actuators to move a lever beam that bears an objective lens for tracking and focusing motions. With
control, nanometer resolution could be achieved. In some environments with very limited working space,
an integrated actuation device with multiple functions would be desirable. We designed novel
magnetorheological (MR) fluid based multifunctional actuators. To decrease the dimension of the actuation
device while enhancing the functionality, a motor part and MR fluid are integrated into one device. The
developed rotary MR actuator possesses multiple functions as motor/generator and clutch/brake. A
self-sensing MR damper with power generation was also designed to integrate energy harvesting, dynamic
sensing and MR damping technologies into one device. These MR actuators and devices are applicable to
various dynamic systems. The multifunctional integration would bring great benefits such as energy saving,
size and weight reduction, lower cost, and high reliability. In this talk, related designs and key results will
be presented.

Recent Trends in Low Power Vlsi Techniques
Prof. Siva Kumar
Head of Department of Electronics and Communication Engineering at
RMK Engineering College, Tamilnadu, India
Abstract:
The growing market of portable (e.g., cellular phones, gaming consoles, etc.) battery-powered electronic
systems demands microelectronic circuits design with ultra low power dissipation. As the integration, size,
and complexity of the chips continue to increase, the difficulty in providing adequate cooling might either
add significant cost or limit the functionality of the computing systems which make use of those integrated
circuits. Though Low Power is a well established domain, it has undergone lot of developments from
transistor sizing, process shrinkage, voltage scaling, clock gating, etc., to adiabatic logic. The Energy
Recovery logic paves way for reusing the power in high speed power hungry circuits. This logic can be used
in memories to save power to a greater extent.

Natural Materials for Thermal Insulation: Mulch and Lava-Rock Characterizations
AurГ©lien P. Jean, Craig Adams, Mario A. Medina , FrГ©dГ©ric Miranville
Reunion Island University, France
Abstract—This paper reports on the thermal characterization, via the thermal conductivity, of natural materials, such as mulch and
lava rock and their usefulness as building insulation. Experiments were carried out using a scale one monitored wall (i.e. heat flux
and temperature sensors) exposed to a heating source on one side and to an air conditioned space on the other. The wall system was
composed of an 8.85 cm thick cavity, where the mulch and lava rock were placed. The cavity was enclosed between two layers of
pine wood (40 mm thick each). After the experiments and statistical data manipulation, the estimated thermal conductivity of the
materials were 0.48 В± 0.001 W.m-1.K-1 and 0.129 В± 0.003 W.m-1.K-1 for mulch and lava-rock, respectively. That is, mulch has a
thermal conductivity comparable to that of bulk hemp while lava rock has a thermal conductivity comparable to that of hemp brick.
These values indicate the usefulness of mulch, compared to the impracticality of using lava-rocks materials for building insulation.

Characteristics of nanostructured TiO2 prepared by one-step soaking method for photovoltaic application
Mi Sun Park, Shi-Joon Sung, and Dae-Hwan Kim
Daegu Gyeongbuk Institute of Science & Technology, Republic of Korea
Abstract—Nanostructured TiO2 films were prepared by a one-step soaking method, which has many advantages, such as simple
fabrication, a short reaction time, and fast growth. We have investigated the growth of TiO2 films by the substrate orientation of the
soaking method, which had an effect on the nanostructure of the TiO2 films. The TiO2 films prepared by this method had various
structures: particulate-flat structure and sphere-flat structure. To determine the effect of the nanostructure of TiO2 films on the
photovoltaic characteristics of solar cells, solar cell devices using the inorganic semiconductor Sb2S3 as a sensitizer were fabricated
by chemical bath deposition (CBD). Our solar cell device, using TiO2 film with a sphere-flat structure as a photoelectrode, exhibited
JSC, VOC, FF, and О· values of 11.82 mA / cm2, 0.49 V, 30.27 %, and 1.74 %, respectively.

in a still water reservoir and thus able to lower the cost of electricity and save the fossil fuels. The newly invented machine is able to
converts the buoyance force energy into mechanical energy of shaft rotation, and thus into the electricity via rotary generator. The
hydraulic buoyant force engine system includes two cylindrical pulleys with belt transmission mounted on the stationary frame that
is submerged into the water. The belt carries the chain of elastic plastic airbags to generate the buoyance force. The empty and
weightless airbags are driven first by the belt and pulleys system to the bottom of a water reservoir where they are filled with the air
delivered by the compressor and then the bulged bags and thus connected belt are driven up by the buoyant force. As a result the
belt and shaft of the connected to the upper pulley generator will be constantly driven by the buoyant force. The paper describes the
details of the engine construction, the amount of power generated by the engine as a function of the reservoir depth and the power
of an air compressor as well as advantages of such engine installations and their impact on the society.

Current State of Applying Smart Materials in Consumer Durables: A Literature Survey
Azrol Kassim, Imre HorvГЎth and Bart Gerritsen
Delft University of Technology, Malaysia
Abstract—Smart materials have drawn substantial attention and interest in a broad range of applications, due to their unique and
superior characteristics. However there is a blurry image over the potential applications of smart materials in consumer durables.
This has stalled further research and decision making in innovating consumer durables based on smart material technologies. This
literature survey investigates the applications of smart materials in consumer durables in a retrospective manner. The analysis
revealed the frequency distribution of the publications based on the reported application on 7 classes of smart materials in ten
consumer durable categories. The results show that shape changing smart material is the most frequently used and widely
distributed class of smart material. Nonetheless, shape changing smart materials applications in consumer durables are still limited.
On the basis of our main findings we discussed about the new opportunities and directions for future research and application in
consumer durables. As conclusion to this research, cross-disciplinary research between the domain of material engineering and
product design, through dedicated methods and software tools were proposed in order to improve the situation.

Gurinder Singh Brar and Gaurav Mittal
Guru Nanak Dev Engineering College, India
Abstract— Electric discharge machining (EDM) widely used mostly in the tool and die industry and the material normally used as
electrode are copper, tungsten, graphite, copper tungsten and copper chromium alloys. In the present work, Electric discharge
machining was carried on H-13 workpiece using powder metallurgy electrodes of copper chromium (CuCr) and conventional
copper electrode. The input parameters selected in the study were current, voltage, duty cycle and retract distance. The output
parameters were material removal rate, tool wear rate, surface roughness and overcut. Experimental results show that CuCr powder
metallurgy electrode gives best results for MRR. Also CuCr powder metallurgy electrodes gives better results for overcut as
compare to conventional copper electrode. It has been seen that electrode type is significant factor for all output parameters.

Recycled cigarette filter as reinforcing filler for natural rubber
Mun Kou Lai, Hiu Hong Teo and Jian Ye Lee
SEGi University, Malaysia
Abstract- Natural rubber is highly resilient and possesses many outstanding characteristics but inferior in aspects like modulus and
hardness. This however can be improved by reinforcement, forming a composite. The rubber compound in this study was prepared
according to the ASTM D3184 standards and reinforced using cellulose acetate (CA) from recycled cigarette filter, partly as an
effort to reduce the amount of waste. Moreover, cigarette filter is highly toxic due to the nicotine content thus requires care when is
recycled. From the rheological and mechanical testing conducted i.e. scorch and cure time, torque, tensile test and tear strength, it
seems to indicate a small amount of up 4 phr (parts per hundred rubber) of CA, is beneficial in improving the properties of the
rubber compound.

Two processing steps involving the root-run formation and the replacement with a sound
Initially, tank fabrication is achieved through the application of both flux-cored arc
A new processing approach was proposed with the modified method in cross-section
preparation, and a low-cost reusable copper backing-wheel device was developed to facilitate the root-run formation using only
submerged arc welding.
Temperature gradient through the device components along the heat-conduction path was monitored to
assure the conductivity of the backing device.
The results suggest that the proposed approach reduced manufacturing time by
removing the initial flux-cored arc welding process used in the conventional welding method. As an effect, the new approach
show promise reduces the overall manufacturing cost of tank fabrication. Based on radiographic testing of tanks fabricated using
the new approach found that circumference joints required little or no welding repair suggesting higher joint quality.

Abstract—A tape spring hinge is one of the most typical deployment devices and is frequently used in miniaturized satellite due to
its simplicity, lightweight, low cost and high deployment reliability. But a tape spring hinge mechanism has limited performance
due to the performance trade-off between deployed stiffness and latch-up shock.
In this study, to improve a conventional tape spring hinge mechanism, SMA damped tape spring hinge is proposed so that a satellite
solar array can be quasi-statically deployed. The test result shows the feasibility of the proposed concept.

The University of Jordan, Jordan
Abstract—A complete technical study on a Hybrid heating system is carried out with the aid of computer simulation. The main
objective of this work was to provide more insight into combining Solar and Diesel energies to be utilized in domestic central
heating. The motivation for such a system was basically the ever increasing Diesel prices in the Kingdome. This work revealed that
the cost of Diesel in heating houses could be lowered by at least fifteen percent if the hybrid system is implemented. Complete
mathematical model of a representative house was derived for the sake of computer simulation. The model was validated and
verified through computer simulations (Matlab Simulink based) with real collected weather data of Jordan (complete year record).
Finally a controller strategy was devised and tested using the derived mathematical model.

Daegu Gyeongbuk Institute of Science & Technology, Republic of Korea
Abstract—A mesoporous TiO2 photo-electrode for dye-sensitized solar cells (DSSCs) was fabricated by an electrospray method
using a solution of dispersed TiO2 nanocrystals (P25). A mesoporous TiO2 disk has a larger surface area than P25. The sub
micrometer-sized TiO2 disk promotes light scattering, thereby increasing the photocurrent conversion efficiency. However, the
electrosprayed TiO2 electrodes have many pores and disconnected electron pathways. Thus, we investigated the enhanced electrical
contact of an electrosprayed TiO2 electrode using a hot-pressing process and a titanium tetrachloride (TiCl4) treatment process. After
optimizing the post-treatment process of an electrosprayed TiO2 electrode, the cell shows conversion efficiency up to 6% at standard
sunlight of AM 1.5.

Abstract—Anti-reflective (AR) layers play an important role in boosting the amount of light entering a device and reducing
reflection losses in a device, thereby enhancing the power conversion efficiency of solar cells. We have coated an AR layer on the
surface of a dye-sensitized solar cell device by using an electron beam evaporation system and investigated the effects of the AR
layer by measuring photovoltaic performance. The AR layer is found to increases the Jsc and О· of the solar cell.

College of science and technology, University of Rwanda, Rwanda
Abstract—Photothermal characteristics of nanofluids are of special importance in the design and performance analysis of solar
thermal collectors with nanofluids as heat transfer media. The present work investigated the photothermal characteristics of the
magnetite (Fe3O4) based nanofluids in zero and applied magnetic fields. Stable kerosene and water based magnetite nanofluids were
prepared via a coprecipitation method and their photothermal characteristics were measured under direct sun. Effects of magnetite
particle volume fraction and magnetic field on the temperature enhancement as function of irradiation time were analyzed. The
results showed that the photothermal characteristics could be enhanced with magnetite nanoparticles used in nanofluids at lower
particle volume fraction. In addition the, the photothermal characteristics of magnetic nanofluids (MNFs) were found to be related
to magnetic field.

Prince of Songkla University, Thailand
Abstract—In this study, the commercial grade of ethanol was used to produce the biodiesel from refined palm oil (RPO) through the
continuous static mixer system. The ethanol, an alternative alcohol to adopt in the ethyl ester production, can be used instead of
methanol, and this alcohol is more eco-friendly than methanol. The 6-meter in length of SUS304 static mixer reactor is an essential
part of mixing the RPO and solution of ethanol and potassium hydroxide to accelerate the base-catalyzed transesterification. The
ethanol were varied at the volumetric flow rate of 30, 40, 50, 60 vol.%, KOH as base-catalyst was varied with the weight to volume
of oil of 10,12,14 gKOH.L-1, to investigate the suitable condition which can converted the glycerides to the maximum purity of
ethyl ester. The results showed that all varied conditions, the ethyl ester conversion was rapidly increased from 0 to over 95 wt.%
when the flowing mixtures flowed through the 1 meter of static mixer. Furthermore, the highest purity of ethyl ester from RPO was
succeeded when the condition: the 60 vol.% ethanol, the 14 gKOH.L-1 of catalyst, 5-meter of static mixer, and 75 ВєC temperature of
RPO, was used in the continuous static mixer.

Abstract—Potential agro wastes (i.e palm kernel shell and coconut shell) for producing low cost activated carbon (AC) was
investigated. In this study, the activated carbon was produced by carbonization, chemical impregnation with KOH and microwave
irradiation. The pyrolysis was carried out at 700 ЛљC in an inert environment for 2 h. Microwave activation was carried out at 400W
for 6 minutes. Characteristics of the material were investigated using Fourier transform infrared spectroscopy (FT-IR) analysis and
scanning electrode microscopy (SEM). Methane adsorption equilibrium data on the activated carbons produced were obtained using
static volumetric method. Microwave palm shell activated carbon (MPAC) and microwave coconut shell activated carbon (MCAC)
recorded highest methane uptake of 2.489 and 1.929 mmol/g at 3 bar, 30 0C. The adsorption data were correlated with Langmuir and
Freundlich isotherms. The results shows that microwave activated carbon from palm shell and coconut shell have good methane

Abstract—Renewable energy is a source of energy that can be recovered and recycled. The recyclable material is removed first
before energy is recovered from the residual waste. In this study, the effect of pyrolysis temperature on the calorific value of
sustainable materials and gas emission quality were carried out. Pyrolysis and non-pyrolysis processes were initially conducted
before calorific value determination. Calorific values of the samples were measured by bomb calorimeter. The sample that contains
the highest calorific value was chosen and compared with coal. Testing of the prepared samples was accomplished using
combustion process. The characterizations of the samples were determined by TGA analysis, SEM, FTIR and elemental analysis.
From the results obtained, it is observed that the calorific value of sustainable material depends on the number of hydrogen, carbon
and thermal energy.

Universidad de Piura, Piura
Abstract—In Peru, jaggery making process has low energy efficiency and it is due to low heat transfer coefficients for natural
convection linked to the sugar cane movement generated by the heat exchange between the sugarcane juice and the combustion
gases. This low heat transfer coefficients are caused by improper heat exchangers designs. In this work, is performed an
experimental analysis that consist in supplie heat to a pot containing sugarcane juice using a hot plate of constant electrical power.
This study consist in identify boiling regimes and estimate the heat transfer coefficients linked to natural convection boiling,
measuring: (i) the temperature at the bottom of the pot (ii) the temperature at the bottom level of sugarcane juice (iii) the
temperature at middle level of sugarcane juice (iv) the temperature at free surface of sugarcane juice (v) rate of water evaporated.
The method of linear regression and the correlation of Rohse now were used for obtaining the values of the heat transfer coefficients

Abstract—Recently, demand of biolubricants has been continuously increased since it is environmentally friendly and renewable.
Therefore, this research focused on the biolubricants production from enzymatic esterification of oleic acid and propanol using
Novozym 435 as a biocatalyst. The esterification experiments were conducted under the optimal conditions, as follows: 45В°C, oleic
acid to propanol molar ratio of 1:2, Novozym 435 loading of 5% based on the weight of oleic acid. It was shown that the optimal
rotation speed at 250 rpm could minimize the effect of external mass transfer limitations and maintained the enzyme activity. The
20
2014 HONG KONG CONFERENCES
conversion of oleic acid from the esterification for 6 h with isopropanol was 76.4%, which was lower than that with n-propanol
(88.9%). Novozym 435 could be reused in the production of propyloleate for at least 5 cycles with maintaining FFA conversion of
94% of its initial value. Moreover, the use of molecular sieve to remove water during the reaction could significantly enhance the
final FFA conversion from 88.9% to 94.7%.

Abstract—A thin-shell silk cocoon (TSC), a residual from the silk industry, was used as an alternative nitrogen (N-) source in ABE
fermentation by Clostridium acetobutyricum ATCC 824. The experimental studies were performed in batch fermentation at 35 В°C
and pH 5.0. The results were compared with the system using yeast extract (YE) as N-source. It was shown that TSC fragments
(TSCf) could be used as a cheap substitute for YE for a certain amount. Under optimum conditions, total solvent of 22.3 g/L (12.7
g/L butanol, 8.0 g/L acetone and 1.5 g/L ethanol) was obtained from the ABE fermentation using the mixture of TSC f and YE as
N-sources. The ABE productivity and conversion yield were 0.15 g/L/h and 0.30 g/g sugar consumption, respectively.

Korea Institute of Industrial Technology, Korea
Abstract-The digital home service proposed here is intended to implement an emotional interface in relation to each user�s condition
by applying living-related convergence technology including IT, BT, electronics and architecture to the residential environment. The
digital home service system operates in the order of information recognition, signal transmission, integrated control, expression. We
have implemented a system that works with the concept step by step weight forest, the sea, healing, depending on the body weight
of the signal. To find out user preferences for the proposed system, a demonstration setting was installed. A questionnaire survey
was conducted with 300 participants in the setting. The survey results showed user satisfaction was high in the order of lighting,
sound, vibration. The user recognition sensing, systerior and LED/optical fiber emotional lighting system are integrated into the
proposed digital home service. The emotion-oriented customized service based on the information of user condition allows users to
control their surroundings at their own discretion. And this study implemented the service infra capable of accommodating user
preferences with the convergence of heterogeneous technologies and industries in a relatively less objective field of emotion, which
is prone to individual differences.

Abstract—The transition between the utilization of Ipv4 and Ipv6 leads ISPs to develop a new mechanism so as to continue services
for customers. In one hand, ISPs are pushed in implementing Ipv6 protocol as the new technology. In another hand, there are many
users and services still provided by Ipv4 protocol. The CPE as an equipment at customer�s premises must be able to pass any kind
of services at any kind of IP traffic on dual stack environment. In order to support communication between Ipv4 terminals beyond
the Ipv4 depletion issue, the CGN DS Lite approach is implemented. This paper presents two features of dual stack CPE which
allow Ipv4 traffic and applications implementing port forwarding operation to communicate through Ipv6 access network. The PCP
capability is taken into account between the CPE and CGN with some UpnP-PCP proxy capabilities in the CPE. We demonstrate
that PCP gives an opportunity for customers in the home network behind the CGN to manage their interactive applications.

State Polytechnic of Padang, Indonesia
Abstract—One of the gunboat weapons that need to stay stable is the cannon. Its unbalance position that caused by pitch and roll
disturbance will influence the target accuracy, target detection, tracking system, object identification and the ability to counter the
threat. In order to determine this disturbance, the balancing control on the movement platform can be solved by using neural
network control and sliding mode control methods. To make an approach, the cannon movement system can be modeled in training
and elevation movements and the disturbances are modeled through pitch and roll mechanisms. The variations in obtained
parameters of training and elevation (moment of inertia) are the non-linearity result of the moving cannon. The system is simulated
to verify the error in the controller�s output processed using the neural network coordination system control and sliding mode
control. The learning process in the neural network is made using back propagation method in order to get the weight value at the
different disturbances which their results are given in the simulation of coordination models. On the other hand, the free chattering
of sliding mode control is implemented in order to make the movement of training and elevation can be controlled for having the
desired angle position in the disturbance of pitch and roll. This paper is based on the study to compare the performance of neural
network control and sliding mode control on the moving platform.

National Institute of Technology, Durgapur, India
Abstract—Multicast Communication over an optical fiber network is treated as a major problem in optical domain. As the need of
one-to-many communication is increasing day by day, researchers are trying to devise novel and efficient approaches to solve this
problem. Although the most of the efforts done in this field is heuristic in nature, evolutionary approaches are also started to be used
to solve this as an optimization problem. In this paper we have used Genetic Algorithm to find an efficient multicast route (tree) to
establish a multicast connection in WDM mesh network. We have proposed a novel fitness function which can optimize multiple
objectives: reaching maximum no. of destinations, minimizing usage of optical channels, minimizing usage of splitters, very
efficiently. We have established the truth of our claim by simulating our proposed algorithm over various optical fiber networks.

analogue-to-digital converter ports. To improve the data quality sent to the base-station, a real-time data analysis should be
implemented at nodes� level, while taking into account their computing power and storage limitations. This paper deals with the
problem of outliers detection and accommodation in raw data. The proposed approach relies on univariate statistics within an
hierarchical multi-agent framework. Results from experiments on a real monitoring scenario, at a major oil refinery plant, show the

Sanjib Sadhu and Niraj Kumar
National Institute of Technology (NIT), Durgapur, INDIA
Abstract—The convex layers of a given point set can be computed by iterative process of finding convex hull after discarding the
points of already computed convex hull. Computation of convex layers has been widely studied in the static environment where the
point set are fixed. In this paper, we propose an idea to compute set of convex layers in dynamic context. There exists an optimal
time algorithm to solve the static version of the problem in O(n logn) time. However, to solve dynamic version of the problem the
suggested algorithm requires O(n^2) time for a set of n points.

An Optimal Inherently Stabilizing Algorithm for Routing over all Node-Disjoint Paths in Exchanged Hypercubes
Thamer Alsulaiman and Mehmet Hakan Karaata
Kuwait University
Abstract—Two paths between a source node and a destination node in a network are node- disjoint if they do not share any nodes
except the end points. Node-disjoint paths have numerous uses in distributed systems including ways to deal with lost, damaged or
altered messages during delivery. Many topologies such as hypercube, star networks, and their variants have been proposed,
providing multiple disjoint paths between a pair of endpoints. The exchanged hypercube is a new topology that is obtained by
systematically removing edges from a binary hypercube. Exchanged hypercube topology increases scalability and relative cost of
the networks by reducing the number of edges per node.
In this paper, we propose a distributed algorithm that is both stabilizing and inherently stabilizing to route messages over all
node-disjoint paths in an exchanged hypercube network.

explore a 3D computerized model of a real-life indoor location, such as a classroom or hospital. For administrative purposes, the
screen displays a 2D overhead view of the map to monitor user progress and location relative to the reconstructed 3D environment.
The system offers two unique interfaces: a free-roam interface where a user can freely navigate and interact with the model, and an
edit mode where an administrator can manage test users, manage maps and retrieve test data. VirtuNav is developed as a practical

application offering several unique features including map design, semi-automatic 3D map reconstruction and object classification
from 2D map data. Visual and haptic rendering of real-time 3D map navigation are provided, and automated administrative
functions including determination of shortest path taken, comparison with the actual path taken, and assessment of performance
indicators relating to time taken for exploration and collision data. VirtuNav is a research tool for investigation of user familiarity
developed after repeated exposure to the indoor location, to determine the extent to which haptic and/or sound cues improve a
visually impaired user�s ability to navigate a room or building with or without occlusion. System testing reveals that spatial
awareness and memory mapping improve with user iterations within VirtuNav. The application is for greater real world
engagement: to build confidence in real world experiences, enabling persons with sight impairment to more comfortably and readily
explore and interact with environments formerly unfamiliar or unattainable to them.

accessible over GPRS from a web enabled phone or Smartphone. Photographs of landmarks are pre-loaded into a central database,
which is then queried by users submitting images from their camera phones. The image recognition algorithm is robust to variations
in both illumination and point of view. In this research, the effective method was suggested for the transmission of the geographic

Secondary Flows in Radial Diffusing Channels
Gopalakrishnan Govindarajan
Dr.M.G.R. Educational & Research Institute, India
Abstract-An approximate method has been developed for the estimation of the secondary flow through a radial diffusing cascade.
The basis of this numerical treatment is on the Reynolds Navier Stokes method.
The theoretical development is based on the channel approach, in that the flow emerging out of the channel is assumed to consist of
two sets of symmetrical vortices, which includes the shroud cross flow principle. The flow is considered to be ir-rotational and
incompressible. This however is a bad approximation for high pressure recovery diffusers. The solution could be extended to
compressible situations – approximate solutions only.

Abstract—Process knowledge including the relationships between manufacturing processes and machining features is one of the
crucial elements needed for various decision making activities in process planning, while the planning is the essential preparative
step of Manufacturing Execution systems. As new technologies emerge, the process knowledge needs to be updated accordingly.
Most of the systems dealing with process knowledge are not flexible enough to accommodate the relevant changes within an
acceptable cost. In this paper, ontology based modeling of the process knowledge is presented. The core process ontology represents
the process knowledge for machining operation selection regarding multi-axis machining feature. Firstly the concepts such as
features, machining methods and process capability are modeled with relevant properties. Secondly the causal relationships between
these concepts are modeled. In addition, the process selection logic is modeled by using rules which describe the match between
machining requirements of a feature and process capability of a machining method. An example shows how the process ontology
can be used in a reasoning mechanism for operations selection.

Biogas source of Energy and Solution to the Environment problems in Rwanda
Anastase Rwigema
University of Rwanda, Rwanda
Abstract—In Africa especially in Rwanda, the development of Biogas technology is imperative for development to occur in
sustainable manner. Using large centralized power generation facilities to provide electricity to rural population and communities is
very expensive and non-viable in Rwanda due to lack of a well dispersed electric grid. In Addition, use of non-renewable fossil
fuels is resulting in increased greenhouse gas (GHG) emissions and attendant increased drivers for climate change. Development of
Biogas systems serves the purposes of solving sanitation, energy and environmental problems by improving good health conditions
and providing a source of energy for cooking and lighting to the communities and households contributing also to the decrease of
GHG emissions. In Rwanda, there are 14 prisons, after genocide of 1994, the inmates increased up to 60,000. Number of prisoners
was from 2,000 up to 7,500 prisoners in one prison[6].
This high number of inmates caused serious sanitation and environmental
problems. Indeed the septic tanks became full and human excreta started to overflow and pollute the environment. In addition, a
very big quantity of fuel wood was used for cooking inmates� food; the consequence was the degradation of the environment.
Similar problems were observed in schools. Solution to the mentioned problems was construction of Biogas systems. In Rwanda
only about 16% of the population have access to electricity.
In order to reduce that deficit of energy, Rwanda Government is
developing other sources of energy particularly Biogas for rural areas which so far do not have connection to the national electricity
grid. Big size (100 m3) and small size (4, 6, 8 and 10 m3) bio- digesters are installed in several institutions and households and they
provide enough Biogas for cooking and lighting in steady of using firewood which is becoming scarce in many areas of the country
and their usage as source of energy causes pollution through production of Carbon dioxide (CO2) released in the atmosphere.A
study made by SNV(Netherlands Cooperation Development Agency) shows that a domestic bio-digester reduces 4.6 tons of
(CO2)per year. Hence, calculation made indicates that the 3,000 domestic bio-digesters currently operational in Rwanda allow to
reduce 13,800 tons of Carbon dioxide (CO2) emissions per year. As organic wastes particularly human excreta and other digestible
biomass are available everywhere, biogas technology can be developed in all the countries worldwide.

between Hong Kong and Reunion Island
AurГ©lien P. Jean, Teddy Libelle, FrГ©dГ©ric Miranville, Mario A. Medina
Reunion Island University, France
Abstract—The aim of this paper is to present the experimental results of a specific vegetated complex partition (VCP) and discuss the
conclusions found from an interesting study case in Hong Kong, especially the presence of a strong upward heat flux in winter.
The experimented VCP configuration have never been tested in Reunion Island. It is located on a small scale building with a sloped
roof covered with steel foil and under a humid tropical climate.
From March to August, the extensive VCP reduced the global average heat flow by 91.61% and the ceiling temperature by 9.3В°C, with
a maximum average reduction of 18.9В°C at noon.
Compares to the results from Hong Kong, three of the four conclusions have been observed or deduced from the experimented
VCP's results. The fourth conclusion (about heat flow loss in winter) have not been observed. But, based on the results, a precision
of the explanation of its origin is proposed: the evaporation process act like an heat loss amplifier.

Reunion Island University, France
Abstract—In Reunion Island, many buildings have been equipped with PV panels on their roofs in order to produce electricity.
These PV systems were built to increase the penetration of renewable energies in the public electricity grid and so reduce
greenhouse effect gases emissions. This type of installation was designed just in order to produce electricity but many works have
shown that PV systems integrated to walls can also cool or heat the buildings. This paper presents how PV systems integrated to
building can be used to help meeting energy needs in two microclimates of the island by cooling or heating the building where it is
installed. To show this, a building simulation code able to model BIPV buildings is used.

Abstract—Buildings in Reunion Island have different thermal performances so the thermal energy storage should be enhanced.
Using phase change materials in the building envelope could be a solution. These materials are able to increase the low thermal
mass of lightweight constructions in order to improve human comfort, maintaining the building ambient thermal comfort closer to
the desired temperature. The main objective of this paper is to present the thermal impact of PCM on two walls of an office with
Reunion Island specific conditions. To this end, the experimental validation of a model based on the apparent heat capacity method
and integrated into a building simulation code is used. The study results are very encouraging.

Abstract—Daylight offers many possibilities. Its proper use is a major asset to develop the design, energy and environmental quality
of a building but also improve the physiological and psychological conditions of the user. New emerging devices, offer the
opportunity to improve visual comfort while, providing energy savings. The light pipes are considered as a part of these innovative
devices. Existing semi-empirical models do not adequately transcribe the behavior of light pipes. The scientific objective of this
study is to investigate the propagation of light within a real test-cell equipped with this device in real weather conditions. The aim is
to better understand the role of each parameter (solar geometry, diffuse illumination, direct illumination, etc.). The results indicated
a difference in light distribution within the test cell between the clear and overcast sky. We target new parameters to take into
account in modeling the phenomenon.

Abstract—This work considers the issue of selection of optimum parameters of low-head microhydropower stations. The input
parameter for determining the data of rotor wheel is relative diameter of sleeve. For justifying the selection of rational values of
sleeve ratio of low-head microhydropower stations turbines method of similarity theory is used. When adhering the geometric
similarity, as well as necessary boundary and initial conditions dynamic similarity is carrying out in the case of equality of Strouhal,
Froude, Reynolds and Euler criteria. Necessity of calculation of scale coefficient О» depends on the definition of Re, Sh, Fr, Eu
numbers. The resulting value of sleeve ratio allows to pass on to definition of the main parameter of hydroturbine. The obtained
dependences can extend the application of the theory of similarity, and the developed simulation methods can be used for
calculation and selection of rational parameters of low-head microhydropower stations.

Reunion Island University, France
Abstract—The green roof technology provides environmental benefits by protecting the base roof membrane of buildings against
global solar radiation and temperature fluctuations and by helping to reduce building�s energy consumption by direct shading.
Although several studies have been conducted to explore the energy performance of green roofs as natural cooling devices, there is
still a lack of data concerning the green roof potential in a tropical environment. The present work aimed to evaluate the behavior of
an extensive green roof for buildings under a tropical climate. The experimental green roof developed was compared to a reference
bituminous roof during a five-month period from the end of the winter season to the summer time. The green roof performance was
explored by evaluating its effect on temperature fluctuations and heat fluxes. Results showed that the presence of plants led to a
decrease in temperature under the green roof. Plants also contributed to a lower heat flux exchange through the green roof and to a
higher restitution of heat gain. Furthermore, the determination of parameters including U-value, R-value and k-value, led to
demonstrate the thermal and energy performance of the green roof in a tropical environment.

School of Mathematical Sciences, University of Chinese Academy of Sciences, China
Abstract—Wind energy is now widely used in many countries as a clean energy. In order to make better use of wind energy, we
need to study various factors affecting the utilization of wind energy.
If we can better predict the wind, we can make full use of
wind energy. Where, combing an energy storage system with a wind farm is an effective way to mitigate fluctuations and improve
the predictability of wind power. Energy storage sizing has been an important part in wind farm planning. This paper presents an
optimization model for determining the capacity of a lead-acid battery integrated with a wind farm. The energy storage capacity
calculated in the model gives the lowest cost and has a significant impact on remedying the prediction error. Besides, the charge and

A Clean Energy Generation System of In-Tandem Combinations Each of Heat Pump, Compressor, and Turbine
in Wind Tunnel
Yee-Chang Feng
National Cheng Kung University, Taiwan
Abstract—This is a series of in-tandem combinations each of heat pump, air compressor, and air turbine disposed in a wind tunnel,
working together to generate clean/renewable electricity. The air compressor, located at downstream of the preceding air turbine,
extracts air from this turbine thus reduces its backpressure and causes pressure drop at the turbine exit.
Turbine output work Wtb is proportional to temperature difference (T3-T4) of turbine inlet/outlet air, which varies exponentially
with turbine outlet/inlet air pressure ratio P4/P3 in adiabatic process as below:
Wtb = MCp(T3 -T4) = MCpT3{1-

where, M=mass flow rate of air; Cp & Cv=constant pressure/volume specific heat capacities of air; k= Cp/Cv=1.4
An ASME paper [1] verifies that a suction blower put at turbine exit reducing back pressure of 200 mbar can increase turbine
inlet/outlet air pressure ratio P3/P4by 25%.
Therefore, Wtb becomes more than those turbines without such blowers as(T3-T4)
becomes larger, thus this unique Clean Energy Generation System of Heat Pumps, Compressors, & Turbines (HPCT
system)achieves producing net useful electric power. In HPCT system, each air compressor works efficiently to reduce air pressure
at preceding turbine outlet, as it extracts more air from the turbine than the blower mentioned in the ASME paper, because
compressors have higher compression ratio than blowers. Thus, such feature gives higher turbine pressure ratio to each
combination of HPCT system than those turbines without blowers (or compressors)to reduce back pressure at turbine exit.
Therefore, HPCT system of higher turbine air pressure ratio P3/P4achievesproducing more turbine output work, as air temperature
at turbine exit simultaneously drops more whenP3/P4 becomes larger.
Heat pump is an efficient device to move heat from low-temperature source to high-temperature sink, and geothermal heat source is
preferable as it provides steady & warmer heat energy. This ―moved‖ heat is used to heat up the air in wind tunnel to offset the
energy extracted by turbine from HPCT system. Also, HPCT system is fully thermally insulated, thus theoretically being of zero
heat loss, as it works adiabatically. P-V&T-S curves and performance of each combination of HPCT system working cycle are
studied to compare it with actual gas turbine cycle and ideal Brayton cycle. Working examples of HPCT system are presented to

HPCT system is a ―COLD” Engine of Zero Carbon Emission, works under moderate energy efficiency and with higher energy
density than most existing renewable energy generation systems. More importantly, it is a simply designed system using only
conventional knowledge, and can be made by the existing technology under the least investment risk.

Abstract—Wind energy, which is a typical green energy, is in the limelight as an energy source to replace conventional fossil fuel. In
this study, information of thesis on the wind energy was used to analyze technical levels by countries, and further verify the relation
between technical levels and technology diffusion by countries and the joint research network. As a result, it was shown that studies

joint researches. Our regression analysis of the relation between technology diffusion and the number of joint researches showed
that the more the number of joint researches was, the more extensively technology diffused. It was, therefore, found out that those
countries, which dominate development of wind energy in advance, are taking lead in development of wind energy technologies.

Haiyan Chen, Bo Sun and Jiandong Wang
College of Computer Science and Technology, Nanjing University of Aeronautics and Astronautics, China
Abstract—Data acquisition anomalies often occur in remote monitoring. In this paper, a software solution is presented to discover
the abnormal monitoring node and predict the monitored data, rather than using hardware maintenance. Firstly, by analyzing the
distribution characteristics of the monitoring data from each node, the highly correlated nodes of the abnormal node are selected.
Then, an integrated BP neural network is applied to build an observational learning model, which can give interactive predictions for
the abnormal node. To solve the under-fitting problem caused by small samples and improve the generalization performance of the
model, we propose a new observational learning algorithm, in which the weights are calculated using the mean squared error (MSE)
of learners on test set. Experiments conducted on the airport noise data set show that the proposed model has satisfying predictive
ability, and the improved observational learning algorithm is more stable and effective than the traditional observational learning
algorithm.

Establishing Dense Correspondence of High Resolution 3D Faces via Möbius Transformations
Jian Liu, Quan Zhang, and Chaojing Tang
National University of Defense Technology, China
Abstract—The aim of the paper is to establish dense correspondence of high resolution 3D human faces. To achieve the goal, this
paper proposes an automatic method to establish dense correspondence of high resolution 3D human faces via Möbius
Transformations. For high resolution 3D faces, geodesic remeshing is used to reduce the number of vertices. Since the extent of the
3D face data varies from example to example, an ellipse fit method is proposed to extract consistently matching face points. The
facial feature points are located by using texture and shape information of 3D faces. These correspondent facial feature points are
used to generate Möbius transformations and achieve sparse correspondence between 3D faces. TPS (Thin-Plate Spline)
transformation is used to represent the deformation of 3D faces by using controlling points which selected from the sparse
correspondence set. For every vertex of the TPS warped reference 3D face, they are projected into every triangle face of the sample
3D face, then the closest projections are used to define the new mesh vertices of the sample 3D face. The sample 3D face with new
mesh shares the same connectivity with the reference 3D face, thus the dense correspondence between the reference 3D face and the
sample 3D face with new mesh is achieved. The experimental results on BJUT-3D face database show that our method achieves
better performance than existing methods.

Abstract—Prediction for potential fishing zone is one of the important activities concerning for the tuna fishing exploration,
conservation and management. Accurate prediction will give more efficient in fishing activities. One of the way to predict is the
classification techniques. Currently, as the state of the art, most of the methods utilize the chlorophyll and SST features. However,
there are still other parameters that can be utilized. In this paper, the other parameters are then observed: ocean currents and salinity
feature. First the results shows that, taking a part of ocean currents together with the chlorophyll and SST feature combination gives
the improvement on the prediction. On other hand, this ocean currents feature is then substituted with the salinity, and the result
shows that the combination between salinity, chlorophyll, and SST also increases the result. Finally, the ocean current and salinity
parameters are combined together with chlorophyll and SST parameters and the result was surprising. It is found that the last feature
combination which includes Chlorophyll, SST, Ocean current and salinity gives the highest result in classification (in NaГЇve Bayes
reaches 69.03%, Decision Tree reaches 82.32% and SVM reaches 68.30% of accuracy) compared to the ―baseline‖ feature
combination including only Chlorophyll and SST (in NaГЇve Bayes reaches 57.44%, Decision Tree reaches 58.91% and SVM reaches
56.74% of accuracy). Therefore it is suggested that the proposed feature can be harnessed for the better prediction of potential
fishing zone.

Abstract—Model matching is at the core of different model management operations such as model evolution, consolidation, and
retrieval. An accurate identification of the similarity and differences between the elements of the matched models leads to an
accurate model matching, which, in turn, leads to better model management. Software metrics are the software engineer means to
quantify the similarity between the elements of the matched models. In this paper, we empirically validate the use of different
metrics for capturing the similarity and the differences between the elements of two matched UML class diagrams. The paper
empirically investigates the improvement of the similarity assessment of the class diagrams through the weight calibration of
compound metrics. The results, reported based on two case studies, show the superiority of the compound metrics over the

Abstract—Evaluation of speakers who are high-risk suicidal compared to those with less clinical depression are critical when the
syndrome underlying a patient�s abnormal behaviour is diagnosed without expertise. This study describes a way to classify the
speech samples collected from groups of depressive and suicidal speakers by employing the speech processing technique in data
analysis. First, the Glottal Spectral Slope (GSS) and Mel-Frequency Cepstral Coefficients (MFCC) were computationally estimated
from the voiced segments detected from the categorized speech sample database. Second, the pairwise classification was then made
on the combination of those extracted vocal features respectively corresponding to the frequency response of the source and the
filter in speech production system model.
The procedure of this research was carried out in order to investigate the discriminative property of the focused vocal parameters
mainly between depressed speakers and high-risk suicidal speaker groups. The result revealed that MFCC and GSS parameters are

constructs of technology acceptance model (TAM) that includes perceived usefulness (PU), perceived ease of use (PEOU) and

attitude. Then data were analyzed through Smart-PLS in order to find out if PU remains the significant determinant of the attitude
that in turn predicts the behavioral intention of using the m-learning technology. This model has moderate explanatory power with
38% of the variance in behavioral intention is from the attitude of the students. Based upon the conclusion, some pedagogical
recommendations have been made for the relevant authorities.

One Day Tour in Hong Kong
For free for all the authors and listeners
The Simple Route: Stanley—Victoria Peak—Repulse Bay
The travel agency will pick you up from our conference hotel around 8:00am.
The excursion will start from driving you to Stanley.
Stanley is a town and a tourist attraction in Hong Kong. It located on a peninsula on the southeastern part of Hong Kong
Island. It is east of Repulse Bay and west of Shek O, adjacent to Chung Hom Kok. Administratively, it is part of the Southern
District.
The Chinese name "Chek Chue" refers to the original village-town but "Stanley" generally refers to all the surrounding areas
of the peninsula.
After tripping round Stanley, the tour bus will drive you to The Victoria Peak, which is a mountain in Hong Kong known as
Mount Austin, and locally as The Peak. The mountain is located in the western half of Hong Kong Island. With an altitude of
552 m (1, 811 ft), it is the highest mountain on the island proper, but not in the entirety of Hong Kong, an honour which
belongs to Tai Mo Shan.
The actual summit of Victoria Peak is occupied by a radio telecommunications facility and is closed to the public. However,
the surrounding area of public parks and high-value residential land is the area that is normally meant by the name The Peak.
It is a major tourist attraction which offers views over Central, Victoria Harbour, and the surrounding islands.
Then we are going to The Repulse Bay. It is located in the south of Hong Kong Island, to the east of Deep Water Bay and to
the west of Middle Bay and South Bay. Middle Island, Hong Kong is located off Hong Kong Island, between Repulse Bay
and Deep Water Bay.
Please identify the one day tour when you register for the conference, if you are interested in it.
Please contact the conference secretary if you have any questions.
