  • New Achievement for Prediction of Highway Accidents

    • Authors: Gholamali Shafabakhsh, Yousef Sajed
      Abstract: Most research has been carried out about crash modeling but little attention to the urban highway. The candidate set of explanatory parameters were: traffic flow parameters, geometric infrastructure characteristics and pavement conditions. Statistical analysis is done by SPSS on the basis of nonlinear regression modeling and during the analysis, principal components are identified to assist the principal component analysis method and more important variables recognized that could exhibit best description of crash occurrence on the basis of available logics. Results indicate that the number of accidents per year increase with: length, pick hour volume and longitudinal slope whereas decreases with radius. Presented models show that crash occurrence is increased with the increase in each of section’s length, pick hour volume and longitudinal slope variables whereas it is increased with the decrease of curvature. The remarkable result in this study was the effect of longitudinal slope variable on crash occurrence.

  • PicoGrid: A Web-Based Distributed Computing Framework for Heterogeneous
           Networks Using Java

    • Authors: Nipun Wittayasooporn, Apikrit Panichevaluk, Yan Zhao
      Abstract: We propose a framework for distributed computing applications in heterogeneous networks. The system is simple to deploy and can run on any operating systems that support the Java Virtual Machine. Using our developed system, idle computing power in an organization can be harvested for performing computing tasks. Agent computers can enter and leave the computation at any time which makes our system very flexible and easily scalable. Our system also does not affect the normal use of client machines to guarantee satisfactory user experience. System tests show that the system has comparable performance to the theoretical case and the computation time is significantly reduced by utilizing multiple computers on the network.

  • Simplified Mix Design Procedures for Steel Fibre Reinforced Self
           Compacting Concrete

    • Authors: Abibasheer Basheerudeen, Sivakumar Anandan
      Abstract: The present study focus on the systematic design methodology for producing a self-compacting concrete (SFRSCC) consisting of steel fibre reinforcements. It is intended to achieve a self-consolidating concrete which can yield dual benefit of self-consolidating properties as well as toughness of the composite. Experimental modelling consisted of designing the mortar phase using manufactured sand (M-sand) as fine aggregate using systematic mix design methodology based on particle packing concept. Optimisation of aggregates was arrived based on packing density concept by conducting slump cone studies. Powder combinations consisting of cement and ground granulated blast furnace slag (GGBFS) were selected by conducting paste consistency test. Finally, superplasticizer dosage was fixed based on Marsh cone studies and volume fraction of steel fibres from slump flow studies. The workability of standard and high strength concrete is affected by the inclusion of steel fibre dosage and the fresh properties revealed the importance of maintaining a high paste volume for better flow ability. Based on the proposed mix design methodology with M-sand a high strength self-compacting concrete was achieved upto 70MPa. Experimental investigations were reported on the other assessment made from fresh and hardened properties of designed self-compacting steel fibre concrete mixes. Also, the outcome of test results revealed the possibility of using M-sand as an alternative for complete replacement of river sand.

  • Synthesis of Na2WO4-Mn Supported YSZ as a Potential Anode Catalyst for
           Oxidative Coupling of Methane in SOFC Reactor

    • Authors: Weerinda Appamana, Sumittra Charojrochkul, Suttichai Assabumrungrat, Wisitsree Wiyaratn
      Abstract: The oxidative coupling of methane (OCM) over a 5%Na2WO4-2%Mn on YSZ, has been investigated in a fixed bed reactor (FBR) and a solid oxide fuel cell reactor (SOFC). A 60% C2 selectivity and a 26% CH4 conversion have been obtained in a FBR at 800oC and CH4/O2 of 4:1. Importantly, an addition of Na2WO4-Mn to YSZ support can significantly enhance the performance of the catalyst especially C2 hydrocarbons selectivity and CH4 conversion. A maximum power density of 7.8 mW cm−2 was achieved at 800°C with CH4 in the SOFC reactor having a 50 μm thick YSZ electrolyte. The methane conversion and C2 selectivity at 800°C were 1.1% and 85.2%, respectively

  • Electronic Kanban System for Rubber Seals Production

    • Authors: Naragain Phumchusri, Thanit Panyavai
      Abstract: A key success for automotive suppliers relies on its on-time delivery and efficient manufacturing process. A case-study rubber seal manufacturer is using just in time (JIT) techniques, requiring efficient process flow with low wastes. However, the majority of the current processes still rely on workers’ expertise that can lead to process errors. In 2011, 699 events of rubber supplying delays were found and 525 events or 75.11% of these delays are due to inappropriate ordering and management of the Kanban system in the rubber preparation process. The objective of this research is, therefore, to improve the rubber preparation process by developing a logical method to identify appropriate times for each step and designing information management for the Electronic Kanban System (E-Kanban) to be able to deliver effective and accurate signaling. This E-Kanban system must be able to automatically indicate when each step in the rubber preparation should start so that the rubbers are prepared and ready for the next moulding process by the time they are needed. We also design user interface for an effective use of the system in actual operation. After the developed E-Kanban system was implemented in the factory from July to October 2012, we found that the number of rubber supplying delays could be reduced to 86 events and only 11 events or 12.79% of these delays are from the rubber preparation process.

  • A Study of the Flyover-Bridge Intersection – Improved Junction

    • Authors: Narabodee Salatoom, Pichai Taneerananon
      Abstract: To reduce a traffic congestion at an at-grade intersection near a big city, one method is construction the special bridge at the old junction in two directions on one of the main highways. It facilitates the traffic volume in the directions of the bridge, but the infrastructure cannot fully solve all of the problems especially on the secondary road. Under the bridge, although it relieves the traffic congestion at the crossroad, still uses the same control similar to the situation “before” such as the fixed time control plan of the traffic signalization. After controlled by this method, it was found that about 30-35% of all traffic volumes diverted to the bridges, and time delay reduced to 30% over the same period. This research is one part of author thesis work, presents the issues that still be found in the existing flyover area and suggesting improvement more benefit such as creating a new cycle phase time and improving the physical area. The SIDRA software is used to determine and point out the appropriate fixed time plans, and using the process of a Road Safety Inspection (RSI) to audit on fields and presents some serious of the traffic problems.

  • Real Time Underwater Obstacle Avoidance and Path Re-planning Using
           Simulated Multi-beam Forward Looking Sonar Images for Autonomous Surface
           Vehicle

    • Authors: Thanapong Phanthong
      Abstract: This paper describes underwater obstacle avoidance and path re-planning techniques for autonomous surface vehicle (ASV) based on simulated multi-beam forward looking sonar images. The sonar image is first simulated and then a circular obstacle is defined and created in the field of view of the sonar. In this study, the robust real-time path re-planning algorithm based on an A* algorithm is developed. Our real-time path re-planning algorithm has been tested to regenerate the optimal path for several updated frames with a proper update frequency between the start point and the goal point both in static and dynamical environments. The performance of proposed method is verified through simulations, and tank experiments using an actual ASV. While the simulation results are successful, the vehicle model can avoid both single obstacle, multiple obstacles and moving obstacle with the optimal trajectory. For tank experiments, the proposed method for underwater obstacle avoidance system is implemented with the ASV test platform. The vehicle is controlled in real-time and moderately succeeds in its avoidance against the obstacle simulated in the field of view of the sonar together with the proposed position stochastic estimation of the vehicle.

  • On the Thermal Performance of the Vapor Chamber with Micro-channel for
           Unmixed Air Flow Cooling

    • Authors: Paisarn Naphon, Songkran Wiriyasart
      Abstract: Numerical and experimental results on the thermal performance of vapor chamber with and without micro-channel under constant heat flux are presented. The mathematical model of the vapor chamber is a two-phase closed chamber with wick sheet and a wick column. A finite volume method with structured uniform grid method system is applied to solve the model. Effects of micro-channel on the temperature distribution of the vapor chamber are considered. The results obtained from the model are verified with those from the measured data. The experimental tests are carried out and good agreement is obtained with the numerical results. These numerical results are useful for the design to improvement thermal performance of the vapor chamber and also diminished the expense and time of the real test.

  • Optimal Dosing of Breast Cancer Chemotherapy using Robust MPC Based on
           Linear Matrix Inequalities

    • Authors: Pornchai Bumroongsri, Soorathep Kheawhom
      Abstract: In this paper, we consider an application of robust model predictive control to optimal dosing of breast cancer chemotherapy. The model-patient mismatch is handled by computing an ellipsoidal invariant set containing the measured patient’s states at each sampling time. An optimal dose of chemotherapeutic agent is obtained by solving a convex optimization problem subject to linear matrix inequalities. In the case study of simulated patients, the results show that the tumor volume can be reduced to a specified target with up to 30% model-patient mismatch. Moreover, the robust model predictive control algorithm can achieve better treatment results as compared with the nonlinear model predictive control algorithm while the on-line computational time is significantly reduced.

  • Review on nanofluids theoretical thermal conductivity models

    • Authors: Periyasamy Mukesh Kumar, Jegadeesan Kumar, Rengasamy Tamilarasan, Seshachalam Sendhilnathan, Sivan Suresh
      Abstract: This review paper deals with the analytical nanofluid thermal conductivity models published by different research groups. It also summarizes the contrary opinion on anomalous thermal conductivity of nanofluids by different research groups. Basically all nanofluid thermal conductivity models have been derived from classical models. Majority of the authors presented the thermal conductivity model based on the Brownian motion of particles and they proposed the random motion of particles is the cause for enhanced thermal conductivity. Though many models formulated on thermal conductivity and nanofluid, there is no universally accepted model and reliable mechanism for enhanced thermal conductivity over the particles volume fraction. The discrepancy between each model may be due to method of dispersion, assumption of particle and base fluid such as single and two phase flow. Therefore this review leads to further investigation on the hotly debated topic of nanofluid thermal conductivity.

  • Analysis of Link Availability in FSO-OFDM System under Various Climatic
           Conditions

    • Authors: Selvi M. Rajendrakumar, Murugesan Karruppaswamy
      Abstract: Free Space Optics (FSO) is an emerging solution for the last mile broad band connectivity where deployment of fiber is expensive. This wireless technology has attracted the researchers due to the ease of erecting along the windows and terrace and the abundant bandwidth available in the unlicensed band. Combining OFDM with FSO gives a hybrid technique – OFDM based FSO or FSO-OFDM in which OFDM symbol modulates the light that passes through free space. Various predictable and unpredictable phenomena cause variation in the light that causes the fading effect of the received signal. Besides the atmospheric effect, the signal power varies within the symbol. The link availability has been calculated by setting threshold power at the receiver. The simulation of the OFDM based FSO system under three climatic conditions namely summer, winter and rainy has been observed that shows the link availability is 99.3% for summer, 98.32% for winter and 98.99% for rainy condition. Under worst climatic condition link availability is 98.17%. Thus FSO- OFDM is able to provide better connectivity even under any atmospheric condition.

  • Joint Requirement of Two Multi-skill Resource Types in Multi-period
           Multi-site Assignment Problem

    • Authors: Siravit Swangnop, Paveena Chaovalitwongse
      Abstract: A classic assignment problem determines how to assign resources to tasks in the best possible way. Over the past years, the classic assignment problem has been extended and more complicated assignment models have been proposed. A multi-period multi-site assignment problem is one extension of the classic assignment problem. The number of site and period are increased to more than one and the decision is extended to consider assigning resources to site while concerning tasks in each site and period. Most multi-period multi-site assignment models do not concern joint of resources for operation; however, in some real-life problems, there is a case in which joint of resources for doing tasks is required. In this study, we consider joint requirement of two multi-skill resource types in the multi-period multi-site assignment problem and propose the mathematical model and heuristic. The developed heuristic is separated into two parts. The first part is to create an initial solution by CPLEX In the second part, to improve solution, algorithms for allocating resources to sites and assigning resources to tasks are developed. The computational experiment is done for studying the characteristic of the proposed problem when joint requirement is added and also evaluating the efficiency of the developed algorithm. The result shows that the complexity of the problem highly depends on the ratio of task requiring one and two resource types and while other parameters are fixed except the number of resource, there is only one range of the number of resource that makes the problem complex. For the efficiency of the algorithm, the developed heuristic can find good solutions in a short time in all ranges of the number of resource in all test problems (average optimal gap of all test problems is 7.25%).
