Hybrid Neural Networks for Real-time Hand Gestures Recognition

Prof. Ho-Joon Kim and Jun-Yong Lee 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.

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.

Waste identification Diagrams: A case applied in ther footwear Industry

Ms. Levi Guimarã es; Cintya Colares; José Dinis-Carvalho; Marcelo Pereira 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.

A Multi-Stage Technique for Automatic Recognition of Medical Diagnostic Kits

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 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.

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.

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.

Numerical analysis of cladding Mg-AZ31 melt with Al-3003 sheets by twin-roll casting

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 of findings will be presented and discussed.

Approximation of Throughput in Hybrid Flow Lines with Unreliable Machines

Prof. Yang Woo Shin, Yeseul Nam, Dug Hee Moon Changwon National University, Korea Abstract We consider the hybrid flow lines in which workstations and buffers are linked along a single flow path one after another. Each workstation has several unreliable machines in parallel and there is a buffer of finite size in front of - 18 -odeling- 18 -- 18 -n. The processing times, time to failure and time to repair of each machine are assumed to exponentially distributed and blocking after service blocking protocol is also assumed. An approximate analysis for throughput in the hybrid flow lines is presented based on the decomposition method. The throughput of the system is evaluated through a decomposition into a set of coupled three-stage subsystems with two buff er spaces which are modeled by level depen-dent quasi-birth-and-death (LDQBD) process. Some numerical examples are presented for accuracy of approximation.

Electric arc furnace dust treatment by the combination of pyro/hydrometallurgical processes

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

- 18 -

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.

Poster Effect of alloying elements and impurity (N) on bulk and grain boundary cohesion in Cr-base alloys

Dr. VICTOR BUTRIM, Dr.IGOR RAZUMOVSKIY, A.G. Beresnev, A. Kartsev, V.I. Razumovskiy, A.S. Trushnikova JSC “Kompozit”, Russia 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 principles calculations. The analysis of the data obtained allows us to single out W, Ta as the best and nitrogen as the worst interatomic bond strengthening elements for both the bulk and GB in Cr-base alloys. To verify these theoretical results by means of experiment, we investigated an influence of W (up 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, Nb, Hf, Zr) adding.

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.

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.

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.

Mr. Mohd Najib Hamdan and Ahmad Zamzuri Mohamad Ali Universiti Pendidikan Sultan Idris, Malaysia Abstract Talking-head animation is an instructional approach that helps students in linguistic learning, 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 research by a Japanese robotics expert named Masahiro Mori in 1970, who had also produced a graph explaining this phenomenon. To overcome these problems, the non-realistic three-dimensional talking-head animation has been developed to ensure that students get the maximum learning from the point of emotional and learning performance. On this regard, the focus of this study was mainly on developing non-realistic three-dimensional talking-head animation. The courseware was developed based on theories, principles and literature overview conducted. The paper also reports the outcome of usability and user satisfaction (PSSUQ) test carried out.

Multimedia Instructional Message (MIM) and Simulation-aided Learning: A Conceptual Framework

Mr. Mohd Syahrizad Elias and Ahmad Zamzuri Mohamad Ali Universiti Pendidikan Sultan Idris, Malaysia 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.

Mr. Jayron Sanchez, Analyn Yumang and Felicito Caluyo Mapua Institute of Technology, Philippines 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

- 23 -

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.

Ms. Azlinda binti Azizi, Hazlina Husin, Nurul Aimi Ghazali, Muhammad Kamil Khairudin, Arina Sauki, Nur Hashimah Alias and Tengku Amran Tengku Mohd 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.

GRAFTING OF LINEAR LOW DENSITY POLYETHYLENE (LLDPE) ONTO TALLOW VIA ANHYDRIDE : EFFECT OF RESIDENCE TIME

Ms.HABSAH ALWI, Suhaiza Hanim Hanipah, Mustaqim Zakaria, Istiqamah Subuki, Munawar Zaman Shahrudin, Abdul Hadi Faculty of Chemical Engineering, UniversitiTeknologi MARA (UiTM) 40450 Shah Alam, Selangor, Malaysia 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

- 26 -

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 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.

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 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).

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 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 - 28 -odeling 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.

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 - 28 -odeling.

Malaysia

Abstract Lost circulation is one of the most troublesome problems encountered in drilling due to uncontrolled

- 28 -

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.

Mr.AHMAD FAIRUZ MANSOR, Nurul Adlina M.J, A.I. Azmi, M.R.M. Hafiezal, K.W Leong Faculty Of Engineering Technology, Universiti Malaysia Perlis (UniMAP) 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 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.

Performance Evaluation of Lightweight Oilwell Cements

Ms.Arina binti Sauki , Muhammad Ilham Juanda, Azlinda Azizi, Mohammad Asadullah, Tengku 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

Increase the Space Trajectory Precision by Using the Proper Assisted Research Method for Inverse 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.

poster 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 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.

A kind of way for measuring the imbalance force of centrifuge

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.

Enhanced PSO Approach for Real Time Systems Scheduling

Assoc. Prof. Dr. Medhat Awadalla and Abdullah Elewi SQU, Electrical and Computer Engineering department, Oman Abstract Systems as asymmetric multiprocessor platforms are considered power-efficient multiprocessor architectures, efficient task partitioning (assignment) and play a crucial role in achieving more energy efficiency at these multiprocessor platforms. This paper addresses the problem of energy-aware static partitioning of periodic real time tasks on heterogeneous multiprocessor platforms. A modified Particle Swarm Optimization variant based on min-min and priority assignment algorithms for task partitioning is proposed. The proposed approach aims to minimize the overall energy consumption, meanwhile avoid deadline violations. An energy-aware cost function is proposed to be considered in the proposed approach. Extensive simulated experiments and comparisons with related approaches have been conducted and the achieved results demonstrate that the proposed partitioning scheme significantly outperforms in terms of the number of executed iterations to accomplish a specific task in addition to the energy savings.

Real Time Data Communication using High Altitude Balloon based on Cubesat Payload

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 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.

In Search of Software Engineering Foundations: A Theoretical and Trans-Disciplinary Perspective

Assoc. Prof. Murat Pasa Uysal Department of Computer Technologies, Ufuk University, Ankara, TURKEY Abstract 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 foundations of SE as a discipline.

data is taking place. In addition, huge data are processed in the network which also consumes energy. The main contribution of this paper is to prolong the battery life of the sensors by using compressive sensing to lessen the transmission activity and data processing. CS is a lossless data compression technique that is used to represent the signals into sparse, linear encoding and transformation matrix, and sparse recovery. Discrete Fourier transform is used to get the nonzero coefficient of the signals. L1 minimization is used to recover the signal into its original form.

Application of Artificial Neural Network and Background Subtraction for Determining Body Mass Index (BMI) in Android Devices Using Bluetooth

Mr. Neil Erick Q. Madariaga and Noel B. Linsangan Mapúa Institute of Technology, Philippines Abstract Body Mass Index (BMI) is one of the different ways to monitor the health of a person. It is based on the height and weight of the person. This study aims to compute for the BMI using an Android tablet by obtaining the height of the person by using a camera and measuring the weight of the person by using a weighing scale or load cell. The height of the person was estimated by applying background subtraction to the image captured and applying different processes such as getting the vanishing point and applying Artificial Neural Network. The weight was measured by using Wheatstone bridge load cell configuration and sending the value to the computer by using Gizduino microcontroller and Bluetooth technology after the amplification using AD623 instrumentation amplifier. The application will process the images and read the measured values and show the BMI of the person. The study met all the objectives needed and further studies will be needed to improve the design project.

Toward A New HDFS Functionalities Using A Probabilistic Distributed Algorithm

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.

Information Hiding: A New Multi Watermark Algorithm using Radon Transformation Omer Siddik and Assoc. Prof. Ersin ELBASI IPEK University, Turkey

- 36 -

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 work we used Radon Transformation (RT) in binary image watermarking. Experimental results show that this new algorithm gives very promising results for geometric attacks.

Virtual Reality for Manufacturing Engineering in the Factories of the Future

Dr. Mohammed Bougaa, Stefan Bornhofen, Hubert Kadima, Alain Rivière L@RIS Laboratory – EISTI, Avenue du Parc, 95000 Cergy-Pontoise, France Abstract This paper discusses the possibilities of applying Virtual Reality (VR) technologies to Manufacturing Engineering, and in particular assesses its role in the Factory of the Future (FoF). We review, classify and compare the recommendations given by four major European reports on the challenges that have to be met for a successful deployment of the FoF, and we identify the potential contributions of VR to this vision in terms of new technologies, worker-factory relationship, modular infrastructure and production efficiency. We argue that VR can be a key technology to support the FoF at all levels of the Systems Engineering approach, either directly by applying it in standard engineering processes, or indirectly by leveraging other useful technologies.
