Abstract
A Cellulase and amylase are important enzymes for hydrolysis of cellulose and starchy material into the
glucose. The performance of the mixed cellulose-amylase immobilized on polysulfone membrane (PSF)
by cross-linked with glutaraldehyde was investigated. PSF membrane consists of 1-methyl-2-pyrolidone
(NMP) as a solvent and using polyvinylpyrolidone (PVP) as an additive was developed. The study
highlighted in the surface structure of PSF membrane, stability of the immobilized enzyme and
reusability of the immobilized enzyme. Morphology studied using FESEM analysis indicated a good
distribution of the pores was formed on the surface of the PSF membrane. The immobilization process
shown no effect on the membrane structure and it was stable to be used as a support in immobilization
process. The optimum operating condition for enzymatic hydrolysis of mixed cellulase-amylase on PSF
membrane was 50°C and pH 5. The maximum glucose produced at the optimum condition was
4.843g/ml. The study also indicated that immobilized mixed cellulase-amylase achieved a maximum
rate of reaction at first recycle of reusable before the rate of reaction decreased rapidly after 5 reusable
hydrolysis cycles.

The Algorithm of Semi-Automatic Thai Spoonerism Words for Tri-Syllable
Mr.NUTTHAPAT KAEWRATTANAPAT
Suan Sunandha Rajabhat University: SSRU, Bangkok, Thailand
Abstract
The purposes of this research are to study and develop the algorithm of Thai language spoonerism
words by semi-automatic computer programs, that is to say, in part of data input, syllables are already
separated and in part of spoonerism, the developed algorithm is utilized, which can establish rules and
mechanisms in Thai spoonerism words for Tri-syllables by utilizing analysis in elements of the syllables,
namely cluster consonant, vowel, intonation mark and final consonant. From the study, it is found that
Tri-syllable Thai spoonerism has 2 cases of spoonerism mechanism. In the first case is a crossing
between the first syllable to the third syllable and second case is a crossing between the second syllable
to the third syllable. From the study, the rules and mechanisms in Thai spoonerism word were applied
to develop as Thai spoonerism word software, utilizing PHP program. the software was brought to
conduct a performance test on software execution; it is found that the program performs Tri-syllable
Thai spoonerism correctly or 90% of all words used in the test and found faults on the program at 10%
as the words obtained from spoonerism may not be spelling in conformity with Thai grammar and not
possible to predict the real answer is to look through the tri-syllable, then the answer is because the
two cases depending on the aim of creating a spoonerism it.

University of Minho – Department of production and systems,Portugal
Abstract.The waste identification diagrams (WID) is a new tool to represent production units with its
different forms of waste, which overcomes some VSM limitations.In this paper the WID is applied on a
production unit of a footwear industry located inthe North of Portugal. The main findings are that WID
representthe current situation of the production system, mainly itsmaterial flows, quantitative
measures for each station(takt time, changeover time, cycle time and WIP), utilization of workers in
value adding and non-value addingactivities, key performance indicators of the system suchas
productivity, resources utilization and throughput time. With this the WID can be an option in terms of
representation of complex production units and in terms of identification ofmore forms of waste.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat fever in human body and
veterinary medicine such as drugs, aspirin, ibuprofen, naproxen and paracetamol. NSAIDs are a class of
drugs that provides antipyretic effects that is used for fever-reducing agent. Fever is normal condition
that is faced by human body when the blood temperature rises and the heat production in the body
increasing and cause human body weak, fatigue, and headache, warmth, sweating and feeling cold.
However, synthetic drugs have dangerous side effect towards human body if over dosages. Thus,
herbal medicine is found out as an alternative way that can be used to treat fever and relief pain. Some
researcher found that AquilariaSubintegra Spp. contains antipyretic properties that can reduce fever.
The aim for this study is to determine the n-hexane extractionof antipyretic properties from planted
AquilarisSubintegra Spp. dried leaves by using conventional oven. The antipyretics properties are
obtained in different drying temperature 40, 50 and 60°C. As the drying temperature increase, the
retention time will be reduced and the presences of antipyretic properties can be detected.

Abstract
Grafting polymerization by reactive small molecules involves the formation of graft copolymers from a
reaction between polymers and monomers. Monomer units can be propagated onto the polymer
backbone to form a graft structure. In the polymer processing industry, the internal mixer is the most
important piece of machinery. The study used the internal mixer as a reactor to make a reactive process
with the interest in residence time,as the residence time is importance in the chemical reaction. By
increase the residence time, the optimum degree of grafting may be occurred. The objectives of this
study are to increase the knowledge and understanding of the internal mixer process, determine
optimum residence time process variables for grafting LLDPE and study the effect of the residence time
- 15 -
toward the LLDPE grafting process. Several residence times was choosing for the specified sample, to
study the effect of the residence time which were 60 s, 120 s, 180 s, 240 s, 300 s and 600 s. Degree of
grafting (DOG) was calculated to determine the grafting of LLDPE grafted copolymers and a series of
samples in which degrees of grafting had been determined by chemical titration. Residence time at 300
s produces the optimum DOG of monomer onto polymer. Longer residence time will produce high
degree of grafting but will cause other issues such as increasing in gel content and lower the
mechanical properties of the grafted polymer.

Universiti Teknologi MARA,Malaysia
Abstract
The use of nanoparticles with carbon dioxide foams has been proposed for enhanced oil recovery due
to their robust chemical stability in harsh environment. The experimental study was performed by using
nanoparticles stabilized carbon dioxide foams to study their recovery of residual oil by varying the
carbon dioxide flow rates on different core samples such as sandstone and limestone. Experimental
setup was divided into two different kinds of experiments which are the injection of carbon dioxide
foams and the injection of nanoparticles assisted carbon dioxide foams in both sandstone and
limestone core samples. For the CO2 foam injection, it was found that limestone has higher oil recovery
than sandstone rock samples with 38.67% recovery and 36.36% recovery for sandstone. With the
nanoparticles assisted injection, the crude oil recovery increased to 41.82% and 45.33% for sandstone
and limestone respectively. Limestone showed the higher porosity reduction at the end of experiment
compared to sandstone with the porosity of 7.56% on limestone and 12.49% on sandstone
respectively. This is due to the nanoparticles strongly absorbed at the limestone surfaces containing
calcite component.

Associat.Pro.Sureerat Polsilapa and Nakarin Sriyowong
Department of Materials Engineering, Faculty of Engineering, Kasetsart University, Bangkok, Thailand
Abstract
This project researched a mechanism of the decomposition of zinc ferrite (ZnFe2O4) to be zinc oxide
(ZnO) and calcium ferrite (Ca2Fe2O5) by using calcium oxide (CaO) from lime as a reducing agent. Zinc
ferrite was mostly found in electric arc furnace dust (EAFD), which is a by product from a steel making
industry. The experiment was simple as following. The EAFD was mixed with lime in mole ratio of zinc
ferrite and calcium oxide at 1:2, 1:3 and 1:4 and then compressed into pellets. Effects of mole ratio,
temperatures and times on the decomposition were studied. The conditions used in these experiments
were 800, 900, 1,000 and 1,100 ºC for 2, 4 and 6 hours. The results showed that the suitable
conditions for the decomposition of zinc ferrite by calcium oxide could be as low as 800 ºC for only 2
hours with mole ratio of zinc ferrite from EAFD and calcium oxide from lime as 1:2. A solubility test was
provided to processed samples at the conditions as 0.1 M hydrochloric acid (HCl) at 50 ºC for 20
minutes. It was found that EAFD from pyrometallurgical treatment could be decomposed to be zinc
oxide and the following by hydrometallurgical treatment could recovery high zinc yield from the
remaining residue. However, EAFD treated by only hydrometallurgical process obtained lower zinc
recovery due to the high stability of zinc ferrite in HCl and most of the solutions.

Department Oil and Gas, Universiti Teknologi Mara, 40450 Shah Alam, Selangor,
Malaysia
Abstract
Lost circulation is one of the most troublesome problems encountered in drilling due to uncontrolled
flow of drilling mud into the formation that likely to happen due to ineffective filter cake. The smaller
particles of drilling mud are able to break through into the larger void spaces in the formation which
lead to lost circulation. Hence, fibrous materials in apple skin being identified to be used as lost
circulation material (LCM) in drilling mud to prevent loss of circulation. Mud rheology tests and API filter
press test are performed on the apple skin in drilling mud to find out the potential of fiber in apple skin
to be used as LCM. From the mud rheology test, it was found that the specific gravity does not affected
by the increasing concentration of apple skin and only a slight reduction in pH value to the acidic
condition of the apple skin. As for API filter press test, the additions of apple skin in mud reduced the
mud filtrate and increase the mud cake formation thickness. Apple skin fibers have a potential to be
used as LCM in drilling mud due to the ability in reducing the mud filtrate and increasing the mud cake
thickness that will prevents mud lost circulation problem to happen.

Amran Tengku Mohd, Nurul Aimi Ghazali, and Nur Hashimah Alias
Universiti Teknologi MARA, Malaysia
Abstract
Drilling through depleted zones and weak formation can prove troublesome since the fracture
resistance reduces from its normal boundary [1]. To successfully drill a hole section requires the
selection of a low density cement slurry to prevent loss circulation while not exceeding the fracture
resistance of the formations exposed. Large number of loss circulation will greatly impact the drilling
cost and rig time. This research is focusing on the performance studies of lightweight oilwell cements
using foam and cenosphere as the lightweight agents.
All tests were conducted according to API
Recommended Practice 10B-2. Three performance tests have been conducted such as density test, free
water test and compressive strength test. The comparison was made at different percentage of
lightweight agents e.g. 10, 20, 30 and 40 percent by weight of cement (%BWOC) respectively. The
findings show the performances of formulated foam cement and cenosphere cement are within API
limit. However, foam cement can reduce the density of set cement in about 8% greater than the
cenosphere cement

A Novel Dovetail Joining Method for Planar Panels with Non-Orthogonal Cut Surfaces
research assistant Martin REIS, Heinz Schmiedhofer, Simon Flöry, Florian Rist, Georg Suter
Vienna University of Technology, Treitlstraße 3/1, 1040 Vienna, Austria
Abstract
The development of complex component assemblies from non-orthogonally oriented panels is
laborious with currently available methods. The reason for this is the lack of integrated solutions in
planning, fabrication and assembly. Thus, applications in architectural design are mostly restricted to
geometrically simple, orthogonal shapes. We present a novel dovetail joining method that aims at
facilitating the realization of polyhedral structures. Dovetail elements as well as panels may be
fabricated using CNC water jet cutting technology. Compared with conventional processes, the
presented method adopts the potential of industrial fabrication strategies and by that increases the
reliability of respective processes while decreasing cost synchronously.

New Methods of Mining Technological System‟s Performance Analysis
Assoc. Prof. BALAN GEORGE, Iosif Andras, Nicolae Ilias ,Sorin Radu
Romanian -German University of Sibiu, Romania
Abstract
The mining production systems, both for underground and open pit extraction consist mainly in a string
of equipment starting with the winning equipment (shearer loader, in case of underground longwall
mining or bucket wheel excavator in case of open pit mining), hauling equipment (armored face
conveyor in longwall mining or the on-board belt conveyor in case of excavators), main conveying
equipment (belt conveyor in both cases), transfer devices, stock pile or bunker feeding equipment. This
system of mainly serially connected elements is characterized by the throughput (overall amount of bulk
coal respectively overburden rock produced), which is dependent on the functioning state of each
involved equipment, and is strongly affected also by the process inherent variability due to the
randomness of the involved processes (e.g. the cutting properties of the rock). In order to model and
simulate such production systems, some probabilistic methods are applied arising from the artificial
intelligence approach, involving unit operations and equipment, as the overall system as a whole,
namely the Monte Carlo simulation, neural networks, fuzzy systems, and the Load Strength Interference
methods. The results obtained are convergent and offer the opportunity for further developments of
their application in the study of mining production systems.

Universiti Putra Malaysia
Abstract
Mechanical properties of formulated biocomposite between acrylonitrile-butadiene-styrene (ABS)
polymer and kenaf whole stem (KWS)fibre have been investigated. This work has been done by
alternating the KWSfibre loading with aim to propose the best formulation for preparing
ABS/kenafbiocompositeby referring to its mechanical properties with the addition of processing aid.KWS
fiber loading up from 10% to 50% are considered in this work and evaluated. It was found that by
increasing the KWS fibre loading, the Young‟s and flexural modulus of the ABS/kenafbiocomposite was
subsequently increased too. Interestingly, the biocomposite strength decreased considerably while the
impact strength drops significantly. ABS/kenafbiocomposite with 50% KWSfibre loading (C-50/50) has
showed better performance compared to other formulation. However, a higher fibre loading was not
considered presently as difficulties during compounding process are to be anticipated.

Optical Properties of Front and Second Surface Silver-Based and Molybdenum-Based Mirrors
Ms.Ennaceri Houda, Abdelilah Benyoussef, Ahmed Ennaoui, Asmae Khaldoun
School of Science and Engineering of Al Akhawayn University, Ifrane 53000, Morocco
Abstract
The solar reflectors used in Concentrated Solar Power (CSP) technologies are either front-surface or
second-surface mirrors.
The advantage of second-surface mirrors over front-surface mirrors is due to
the fact that the reflective layer in second-surface mirrors is covered from the front-side by glass, which
- 18 -
allows protection against degradation factors and aggressive outdoor conditions.
In this work, front
surface mirrors and second-surface mirrors were prepared based on two reflective layers (Silver and
Molybdenum). A comparison between the optical properties of the two mirrors‟ architectures was
conducted using a Perkin Elmer LAMBDA 950 UV/Vis/NIR Spectrophotometer.
The results show that
first-surface mirrors top-protected with amorphous Aluminum Oxide (1μm thick) layer show a higher
specular reflectance compared to second-surface mirrors, which makes Al2O3-top-protected
front-surface mirrors the best candidate in CSP application. The deposition of the Al2O3 layer was
conducted using the Ion Layer Gas Reaction (Spray-ILGAR) technique, which did not alter the optical
properties of the unprotected mirrors, conserving a high specular reflectance of the Silver-based
first-surface mirrors (94% in the Near Infrared range).

Abstract
Enhanced oil recovery (EOR) can extend the life of an oil field by providing additional drive mechanism
to the crude oil. The use of carbon dioxide (CO2) in EOR application has shown a good potential, but it
has some weaknesses such as viscous fingering. Viscous fingering problem can be solved by reducing
the CO2 gas mobility, which can be achieved by transforming the CO2 gas into surfactant-stabilized
foam. However, surfactant-stabilized foam is not very stable under harsh reservoir condition, which
could be handled by introducing nanoparticle-stabilized CO2 foam. Thus, this paper aims to investigate
the mobility of nanoparticle-stabilized CO2 foam at varying brine salinity (1 - 4 wt%), concentration of
AOS surfactant (0.01 - 1 wt%) and concentration of nanoparticle (0.05 - 1 wt%). The volumetric phase
ratio was fixed at 8 CO2/aqueous. The sand pack foam flooding test was conducted to measure the
effectiveness of the formulated foam to displace the oil inside the porous medium through mobility and
oil recovery measurement. It was found that foam mobility is inversely proportional to oil recovery.
Mobility decreased when increase of brine salinity, surfactant and nanoparticle concentration, which has
increased the oil recovery. Thus, it is important to reduce the foam mobility for efficient displacement
process, which could minimize viscous fingering and enhance the oil recovery. This could be achieved by
increasing the viscosity of displacing fluid (foam) for more stable displacement in EOR application.

Mr. Natnapat Gaviphatt, Prabhas Chongstitvatana,Chedtha Puncreobutr
Department of Computer Engineering, Chulalongkorn University, Phayathai Road, Pathumwan,
Bangkok, 10330, Thailand
Abstract
Porosity is a major problem occurring in aluminium alloy casting. During the process of solidification,
alloy would shrink and emit dissolving hydrogen causing porosity formation inside the solidified part
which leads to mechanical properties degradation. This research aims to produce a formula to explain
the resulting porosity with the initial chemical compositions and cooling rate. A mathematic model is, at
first, inferred from previous researches to be a template function. Differential Evolution is utilized to
generate inner polynomial parts and to find appropriate coefficients to experimental data obtained from
other publications. The optimized function promisingly shows good fit to the problem domain
demonstrating that the resulting function is an efficient model to explain porosity formation behaviour.

Prof. Jong-Jin Park
Hongik University,Korea
Abstract
Sheets of magnesium alloys are expected to be applied for exterior/interior panels and structural
components in the automotive industry because of their good physical properties. However, poor
corrosion resistance of the sheets needs to be improved andcladding with aluminum alloys has been
known to be efficientfor the improvement. Besides various processesincluding laser welding, hot
pressing, diffusion bonding and casting, twin-roll casting has been proposed as a competitive process
for cladding in recent years. In the present investigation, numerical analysis of a cladding process was
performed in which the melt of Mg-AZ31 was supplied between two sheetsof AA3003 in a vertical
twin-roll caster. The melt was cooledand bonded to the sheets, producing a cladded sheet with a desired
thickness. The heat of the melt should be properly extracted through the sheets and the rolls in order to
produce a cladded sheet with no defects.Therefore, important parameters in this process were initial
temperatures of the melt and the sheets, roll speed and roll contact angle. Through the
presentnumerical analysis, required roll-separating force and roll torque were able to be found and the
process was evaluated in view of capacities of the twin-roll caster. Also the complex thermo-mechanical
phenomenon during the process comprising melt flow, cooling, solidification and rolling was analyzed to

provide information on various aspects of final properties. The temperature distribution at the interface
between Mg-AZ31 and AA3003 was also found which was critical for a sound interfacial bonding. Details

Surface roughness analysis of carbon/glass hybrid polymer composites in drilling process based on
Taguchi and response surface methodology
Ms. TAN CHYE LIH, Azmi, A.I. and Muhammad, N,
UNIVERSITI MALAYSIA PERLIS, MALAYSIA
Abstract
Drilling is an essential secondary process for near net-shape of hybrid composite as to achieve the
required dimensional tolerances prior to final application. Dimensional tolerance is often influenced by
- 21 -
the surface integrity or surface roughness of the workpart. Thus, this paper aims to employ the Taguchi
and response surface methodologies in minimizing the surface roughness of drilled carbon-glass hybrid
fibre reinforced polymer (CGCG) using tungsten carbide, K20 drill bits. The effects of spindle speed,
feed rate and tool geometry on surface roughness were evaluated and optimum cutting conditions for
minimizing the aforementioned response was determined. Subsequently, response surface
methodology (RSM) was utilised in finding the empirical relationships between experimental
parameters and surface roughness based on the Taguchi results. The experimental analyses reveal that
surface roughness is greatly influenced by feed rate and tool geometry rather than the spindle speed.
This is due to the increment of feed that attributed to the increased strain rate and hence, deteriorated
the surface roughness of the hybrid composite. The predicted results (via regression model) and
theoretical results (via additivity law) were in good agreement with experiment results. This indicates
that the regression model from response surface methodology (RSM) can be used to predict the surface
roughness in machining of CGCG hybrid composite.

Abstract
Effect of comprehensive alloying system (W, Ta, Nb, Mo, V, Hf, Ti, Zr, Ni) and impurity N on cohesive
properties of the bulk and the special high-angle grain boundary (GB) Σ5 (210)[100] in Cr-base alloys,
as well as segregation behavior of impurities at the GB and the (210) free surface are studied by first

to 10 wt. %), and (Ta, Nb, Hf and Zr) on mechanical properties of Cr-base alloy. We observed an
increasing of the strength properties due to W addition and increasing of the plasticity as a result of (Ta,

Abstract
Cutting fluid is a well-known as one of an important element in machining process. However, the
consumption of mineral oils as cutting fluid has been raising concern due to worldwide interest in
- 22 -
environmental and health matters. The application of vegetable-oil based lubricant is seen can
overcome the problem but requires a research study about the machinability. This research paper
represents the machinability of using several possible vegetable oils as cutting fluid in term of chip
formation and tool wear during drilling operation on stainless steel, AISI 316. In particular, the
performance of the vegetable oils; palm, sesame, olive and coconut oils were compared under
minimum quantity lubrication (MQL) technique. The result reported that the coconut oil indicates the
best machinability in term of highest and uniform chip thickness and least wear on the drill bit under
same condition with others. These performances are followed by palm, olive and sesame oil. In
additional, the viscosity measurement indicates that coconut oil has the lowest value which can
possesses better fluidity and faster cooling capacity than other oils. Overall, coconut oil is recommended
as viable alternative lubricants during drilling of stainless steel.

Abstract
Talking-head animation is an instructional approach that helps students in linguistic learning,
- 25 -
especially in the pronunciation aspect. However, the use of talking-head animation has caused some
emotional uneasiness among students when the design and realistic level of the animated characters
are too human-like. This phenomenon is known as „Uncanny Valley‟ and was corroborated through a

Abstract
Simulation-aided learning has the ability to attract the attention and interest of students to learn.
However, the effectiveness of simulation-aided learning requires adequate instructional support to
sufficiently achieve the learning objectives. Multimedia Instructional Message (MIM) serves as an
instructional support in building this meaningful learning, especially in helping the exploration of
complex simulation application, abstract learning content delivery and delivery of learning that
requires a combination of skills. Effective MIM strategy depends on the selection of images and the
medium of communication used in the delivery of teaching and learning strategies. The effectiveness
of the image depends on the form of the graphics used either printed static graphics, digital static
graphics or animated digital graphics apart from other factors such as learning styles and students‟
prior knowledge. Taking these into consideration, this paper proposes a conceptual framework for
research related to simulation-aided learning.

Technical innovations and trends have been changing from time to time as a major driving force for
Software Engineering (SE). Although it can be regarded as a relatively young discipline usually driven
by industrial needs or practices, fundamental problems of SE still continue to exist. It is thought that
the problem may be not only in adopting a domain specific technology or method, but also in
understanding the foundations and use of theories in SE. Therefore, investigating the
trans-disciplinary aspects of SE may pave the way of some solutions while it may shed light on building
the theoretical background of possible empirical studies. However, the review of SE literature shows
the little effort given to this research gap, and thus, this paper attempts to offer a conceptual
framework and brings a different perspective for understanding the theoretical and trans-disciplinary

Abstract
The visually impaired individual may use a cane, guide dog or ask for assistance from a person. This
study implemented the RFID technology which consists of a low-cost RFID reader and passive RFID
tag cards. The passive RFID tag cards served as checkpoints for the visually impaired. The visually

impaired was guided through audio output from the system while traversing the path. The study
implemented an ultrasonic sensor in detecting static obstacles. The system generated an alternate
path based on A* algorithm to avoid the obstacles. Alternate paths were also generated in case the
visually impaired traversed outside the intended path to the destination. A* algorithm generated the
shortest path to the destination by calculating total cost of movement. The algorithm then selected the
smallest movement cost as a successor to the current tag card. Several trials were conducted to
determine the effect of obstacles in the time traversal of the visually impaired. Dependent-sample
t-test was applied for the statistical analysis of the study. Based on the analysis, the obstacles along
the path generated delays while requesting for the alternate path because of the delay in transmission
from the laptop to the device via ZigBee modules.

Dept. of Computer Science and Electrical Engineering, Handong University, South Korea
Abstract
In this study, we present a three-dimensional convolutional neural network and a fuzzy min-max
neural network for a gesture recognition system. The convolutional neural network generates a 3D
feature map from the image sequence of a gesture signal. The spatial structure of the receptive field
in the model is extended along the time axis. The center of the three-dimensional processing element
shifts through the spatial and temporal domain of the cube. Thus, the proposed model is not only
robust to spatial variance but also to temporal variance. In addition, we propose a methodology to
select an effective feature set by extending the fuzzy min-max neural network model. We introduce
an algorithm to compute the factors which can measure the relevance between the features and the
gesture pattern classes. From the experimental results, we have shown that the proposed model can
reduce the amount of the feature data and remove ineffective features and erroneous features in the
learning data set.

Mr. Joong-Eun Jung and Ho-Joon Kim
Handong University, South Korea
Abstract
An object detection and image analysis technique for automatic recognition of diagnostic kits is
presented. The recognition process consists of four stages: region segmentation, illumination
compensation, qualitative analysis and quantitative analysis. In this study, we present a target
detection process using the Hough transform and a three-level region segmentation method. For the
image analysis process, an illumination normalization method using a compensation curve is
proposed. We define a data conversion function which is trained by the reference image pattern data.
From the training data, the compensation factor depending on the pixel value range for each color is
calculated. The experimental results show that the suggested method can improve the reliability of
diagnosis by overcoming several constraints such as the object location in test image, the changes of
background image, the illumination condition and the distance between the camera and target
objects.

Automatic Speaker Recognition System in Adverse Conditions - Implication of noise and reverberation
on system performance
Mr. Khamis A. Al-karawi, Ahmed H. Al-Noori, Francis F. Li and Tim Ritchings
Salford University, UK
Abstract
Speaker recognition has been developed and evolved over the past few decades into a supposedly
mature technique. Existing methods typically utilize robust features extracted from clean speech. In
real-world applications, especially security and forensics related ones, reliability of recognition
becomes crucial, meanwhile limited speech samples and adverse acoustic conditions, most notably
noise and reverberation, impose further complications. This paper is presented from a study into the
behavior of typical speaker recognition systems in adverse retrieval phases. Following a brief review,
a speaker recognition system was implemented using the MSR Identity Toolbox by Microsoft.
Validation tests were carried out with clean speech and the speech contaminated by noise and/or
- 29 -
reverberation of varying degrees. The image source method was adopted to take into account real
acoustic conditions in the spaces. Statistical relationships between recognition accuracy and signal to
noise ratios or reverberation times have therefore been established. Results show noise and
reverberation can, to different extents, degrade the performance of recognition. Both reverberation
time and direct to reverberation ratio can affect recognition accuracy. The findings may be used to
estimate the accuracy of speaker recognition and further determine the likelihood a particular
speaker.

Character Image Semantic-Based CAPTCHA
Aziz Barbar and Assist. Prof. Anis Ismail
Lebanese University, Lebanon
Abstract
CAPTCHA is almost a standard security technology, and has found widespread application in
commercial websites. Image recognition CAPTCHAs faces many potential problems which have not
been fully studied. It is difficult for a small site to acquire a large dictionary of images which an
attacker does not have access to and without a means of automatically acquiring new labeled images,
an image based challenge does not usually meet the definition of a CAPTCHA. They are either
unusable or prone to attacks. In this paper, we propose the Character Image Semantic (CIS) based
CAPTCHA that will combine both Image and Text into one CAPTCHA which will strengthen it and does
not make it human solvable. Benchmarks will be discussed after conducting both Usability and
Security tests with a clear set of results that show the accuracy of the proposed solution compared to
other existing ones.

Mr. Ismail Hind and Ali Dahmani
Faculty of Sciences Abdelmalek Essaadi University, Morocco
Abstract
Distributed systems are computing systems where a number of components cooperate by
communicating over a network. Few systems are still working in a stand-alone system where the user
interface, persistent data and applications resided in one computer. However, the majority of
nowadays systems are designed to work in distributed systems.
Provide mechanisms for the storage and the manipulation of large amount of data is one of the
largest technological challenges in software systems research today. Social media and web services
produce an impressive amount of data daily. In this context, Hadoop Distributed file system (HDFS) is
an open source software framework for distributed storage and processing of very large data (Big
Data).
In this paper we introduce new functionalities for Hadoop Distributed File System using probabilistic
distributed algorithms, our proposition is working in both homogenous and heterogeneous HDFS
nodes which can reduce the communication cost.

Prof. Haklin Kimm, Jin S. Kang, Bob Bruinga, Ho-sang Ham
East Stroudsburg University, USA
Abstract
High-altitude balloons can carry small payloads to altitudes higher than 100,000 feet into the
stratosphere to so called “near-space”, where satellite components and payloads can be tested in
harsh environment to simulate the actual space environment. In particular, a high-altitude balloon
flight with satellite communication payloads weighing up to a few pounds is a cost-effective to test the
link. In this balloonSat project, several challenges in the stratosphere testing of CubeSat satellite were
- 30 -
explored. The focus of the test included functionalities of batteries and 2.4 HGz transceiver in low
temperature and long range. In addition, the GPS-enabled radio system functionality was tested for
changing altitude and velocity during the flight. A 9 degree-of-freedom sensor logged the flight
condition throughout the mission. Using the GPS and Automatic Position Reporting System (APRS), a
balloonSat was tracked and recovered successfully. The results showed that all components tested
functioned well.

Optimization of the mask size on the detector pixels for improved MTF
Mr. Haeng-Pal HEO, Sung-Woong Ra
Chung-Nam National University, Daejon, Korea
Abstract
Performance of the detector included in the earth observation electro-optical camera system
determines most of the important performance parameters of the whole system. SNR(Signal to Noise
Ratio) and MTF(Modulation Transfer Function) are the most important performance parameters but
these two parameters disagree with each other in the selection of many system design parameters. In
order to have better SNR, the integration time should be as long as possible because the shot noise is
the dominant one in the total noise. However, long integration time gives adverse effects on the MTF
performance because it will give more chance of signal blur. Even though almost one hundred percent
of the fill factor in the detector architecture results in higher quantum efficiency and eventually yield
better SNR, it will cause much more chance to the electron generated by the incident photon, to reach
to the adjacent pixel. Therefore, reducing the fill factor on the detector pixels will have positive effects
on the MTF but negative effects on the SNR. However, as the system performance goes higher, better
MTF is much harder to achieve than SNR because the integration time can be prolonged utilizing
some kind of TDI(Time Delayed Integration) technique. This is one of the reason the fill factor needs
to be diminished intentionally. The size of the mask located at the edge of the pixels to reduce the fill
factor, should be optimized in order to fulfill both of MTF and SNR performance. It is presented that
the pixel masking scheme and determination of the mask size to fulfill both requirements of MTF and
SNR.

Information Hiding: A New Multi Watermark Algorithm using Radon Transformation
Omer Siddik and Assoc. Prof. Ersin ELBASI
IPEK University, Turkey
Abstract
There are basically two approaches to embed a watermark in a multimedia element: spatial domain
and transform domain watermarking. In the spatial domain, the watermark is embedded by modifying
the pixel values in the original image. Transform domain watermarking is similar to spatial domain
watermarking; in this case, the coefficients of transforms such as Discrete Cosine Transform (DCT),
Discrete Fourier Transform (DFT) or Discrete Wavelet Transform (DWT) are modified. In this research
- 31 -
work we used Radon Transformation (RT) in binary image watermarking. Experimental results show
that this new algorithm gives very promising results for geometric attacks.

Kinematics Problem
Prof. Olaru Adrian, Olaru Serban and Mihai Niculae
University Politehnica of Bucharest, Romania
Abstract
Inverse kinematics model of the industrial robot is used in the control of the end-effecter trajectory. The
solution of the inverse kinematics problem is very difficult to find, when the degree of freedom increase
and in many cases this is impossible. In these cases is used the numerical approximation or other
method with diffuse logic. The paper showed one new method for optimization of the inverse cinematic
solution by applying the proper assisted Iterative Pseudo Inverse Jacobian Matrix Method coupled with
proper Sigmoid Bipolar Hyperbolic Tangent Neural Network with Time Delay and Recurrent Links Method
(IPIJMM-SBHTNN-TDRLM). In the paper was shown one case study to obtain one space circle curve by
using one arm type robot and the proposed method. The errors of the space coordinates of the circle,
after applying the proposed method, was less than 0.001. The study has contained the determining the
internal coordinates corresponding to the external coordinates of the circle space curve, by solving the
inverse kinematics with the proposed method and after that, by applying the forward kinematics to this
coordinates, were obtained the external coordinates, what were compared with the theoretical one. The
presented method is general and it can be used in all other robots types and for all other conventional
and unconventional space curves.

St. Petersburg Politechnical University ,Russian Federation
Abstract
The article deals with the dynamics of wire transmission line while the robot-inspector is moving on it. To
ensure proper and safe operation of the machine, mathematical modeling based on the Lagrangian
mechanics has been conducted. The wire is considered as a stretched string with additional bending
stiffness, and the robot-inspector as moving mass and pendulum. As the result saw-tooth oscillations
have been observed in the vertical plane and they cause parametric oscillations in the perpendicular
plane. Advanced method of mathematical modeling of inspection robot motion on conductors allows us
to choose the design parameters and the law of motion, in order to prevent accidents and ensure safety
of personnel.

Sensorless Control Based On Virtual Neutral Voltage for BLDC Motor Drive
Dr. Chih-Hsien Yu and Chyuan-Yow Tseng
National Pingtung University of Science and Technology, Taiwan
Abstract
Based on the characteristics of the back electromotive force (back-EMF), the rotor position information
- 32 -
would be detected. Hence, the main theme of this paper is to design a practical approach to detect the
zero cross point (ZCP) of back-EMF through virtual neutral voltage for sensorless brushless direct
current (BLDC) motor drives. In contrast to conventional methods, the real neutral voltage of motor is
not needed. In order to compensate the phase delay of the back-EMF due to low-pass filter (LPF) under
different speeds, a voltage-controlled phase shifter, consisted of hysteresis comparator and
voltage-controlled resistor (VCR), is proposed in this paper. The detail circuit model is introduced and
some experimental results obtained from a sensorless prototype are shown to confirm the practicality of
proposed senosorless drive method.

Muhammed Arif Sen and Assoc. Prof. Mete Kalyoncu
University of Selçuk, Turkey
Abstract
The inverted pendulum system is a challenging control problem in the control theory, which continually
moves away from a stable state. The paper presents the design of a Proportional-Integral-Derivative
(PID) controller for a single-input multi-output (SIMO) inverted pendulum system and using the Bees
Algorithm (BA) to obtain optimal gains for PID controllers. The Bees Algorithm optimizes the gains so
that the controller can move the cart to a desired position with the minimum amount of the change in
the pendulum‟s angle from the vertically upright position during the movement. The tuning aim is to
minimize the control responses of the cart‟s position and the pendulum‟s angle in time domain.
MATLAB/Simulink simulation has been performed to demonstrate that the effects on the system
performance of PID controllers with optimal gains. The obtained results show that the tuning method by
using the Bees Algorithm produced PID controllers successfully within the controller design criteria.
Following a description of the inverted pendulum system and the Bees Algorithm, the paper gives the
obtained simulation results for the system demonstrating the efficiency of the design.

Quang Nhat Nguyen Le and Assoc. Prof. Truong Thinh Nguyen
University Of Technology and Education Ho Chi Minh City, Viet Nam
Abstract
IPMC (Ionic Polymer Metal Composite) is promising candidate actuator for bio-related applications
mainly due to its biocompatibility, soft properties and operation in wet condition. In this paper, a new
actuator will be presented. The tubular actuator, based on the concept of tip-displacement of IPMC
actuator and capable of generating bending of tube with surface outside electrodes, was proposed and
studied experimentally. The actuator is a Nafion tube consisting of an even number of Pt segments
along the length, which are plated outside of tube surface, and the Pt segments act as electrodes to
apply the driving voltage. The experimental data measured on prototype actuators prove the proposed
concept of bending depend on the shape of Nafion. Show that the actuator functions well both
displacement and force.

Mr. Qian Liu, Yuanxun Liu, Xiong Xin, Deng Zhigang
Institute of Systems engineering, China Academy of Engineering Physics, China
Abstract
Centrifuge is this kind of device which supplys acceleration environment through the rotation of the arm
of the centrifuge. Centrifuge is widely used in soil tests and environmental simulation tests. Monitoring
system of real-time imbalance force is important equipment for the centrifuge to ensure stable
operation. While working of the centrifuge, it will be affected by the imbalance force more or less at all
time. It will also obviously increase abrasion of the bearings and influence the life of the bearings of the
centrifuge. Even more, some serious accidents would happen possibly. In this paper, the causation of
the influence of the imbalance force to the centrifuge is introduced and a new kind of measuring way for
the real time imbalance force is proposed. Furthermore, working principle and computing expressions of
the way of the measuring are also introduced particularly in this paper. Moreover, this kind of measuring
way provides theory basis for the design of monitoring system which aims at monitoring the real-time
imbalance force.

Numerical Modeling of Residual Stress Field of Bolt Treated by Laser Shock Peening
Ms Liu Yuanxun, Zhang Zhixu, Feng Xiaowei, Liu Qian
Institute of Systems engineering, China Academy of Engineering Physics, China
Abstract
Laser shock peening (LSP) can significantly improve the fatigue life of metals by introducing plastic
deformation and compressive residual stresses near the surface. And it can be applied on curved
surfaces and controlled precisely, thus it is suitable for strengthening bolts. In this paper, a
comprehensive three-dimensional model is presented to predict the residual stress field of bolt treated
by LSP. According to the characteristics of shock pressure, the simulation includes two steps: (i) explicit
dynamics analysis for transient stress and strain in earlier stage of LSP; (ii) implicit static analysis for
stable stress and strain at last. The simulation results show: when the transition zone of bolt head and
shaft is treated by LSP with a laser power density peak of 8.4 GW/cm2, a residual compressive stress
field forms there, with stress values between -250MPa and -100MPa and a depth of 1mm. This indicates
treating the area of bolt easy to fail by LSP can induce compressive residual stresses in the area, which
will help to improve the fatigue resistance of bolt.
