Title: Traffic Information Based Power Saving Mechanism
Authors: Ju No Han, Seong Gon Choi
Abstract: This paper proposes the standby power saving mechanism that the user can terminate home network appliance (Le. Personal Computer) power and standby power at the remote site. Generally, for the power management of the home appliance, it has to be put through the physical contact. In the proposed mechanism, the smartphone is offered the power on/off state information of the home network appliance on a real-time basis. The user can transmit the power-termination order to the home network appliance through the smartphone. If the home gateway receives the power-termination order from the smartphone, the power-termination order is sent to the home network appliance and the standby power is blocked. Its power and standby power can be blocked through the method to be proposed even through the user is not physically contacted with the home appliance. That is, the proposed mechanism gives convenience to the user in electric power management aspect. In addition, the power saving can be done, because reducing the unnecessary operation time and blocking the standby power of the home network appliance.

Authors: Jonathan AP Marpaung, Mangal Sain, HoonJae Lee
Abstract: Cloud computing is an increasingly attractive solution to providing cheap, scalable, and easy to deploy computing services. This paper presents a survey on the middleware technology used to integrate different cloud platforms/services, applications running in the cloud, and the cloud with on-premise data centers. We discuss the ongoing research projects and solutions being developed such as Altocumulus, AppScale, Cloudify, and mOSAIC. We analyze the features already available in current solutions as well as the future technology and standards needed to ensure seamless integration and more widespread adoption of cloud computing solutions.
Title: The Current Status of Medical Physics in Asia-Oceania
Authors: TS Suh
Abstract: Asia has a diverse cultural and economical background. Asia-Oceania Federation of Organization for Medical Physics (AFOMP) was born in July 2000 during the World Congress 2000 in Chicago. The aim of AFOMP was to provide a solid relationship and useful information for closer collaboration and mutual support among the AFOMP members. The purpose of this presentation is to introduce the status of medical physics in Asia-Oceania providing the information of organization, regional congress, the status of medical physicist, etc. One of major role of AFOMP is to support the development of medical physics in Asia region. To improve the status of medical physicists in Asia, a goal-oriented action plans is required: especially, developing advancement of medical physics in developing countries, strengthening the education, training and professional development of medical physicists, and promoting good relations and the exchange of information with other international related organizations through regional congress and website etc.
Title: Design for rebirth (DFRb) and data structure
Author: Christian Mascle
Abstract: In this paper, rebirth, the methodology of design for rebirth antedate structure which it requires will be examined. Rebirth is a global strategy of product analysis for sustainable development. A methodology is developed to conceive a product according to objectives defined by its end of life and its generic engineering requirements, and this methodology is implanted in a framework. Our data structure is based on topological information from a boundary representation (B-rep) model and it processes all information relative to the life cycle of the product. The software, based on this data structure, allows predefining certain characteristics based on knowledge of the company or on the data base. This facilitates its use for a wide range of applications.

Abstract: Vehicular ad-hoc networks (VANETs) have become the focus of much discussion due to its potential role in helping to improve traffic management and safety and enable a wide range of value-added services such as collision warning/avoidance and work zone warning. Because information transmitted over a vehicular network is sensitive and can affect important safety decisions, security requirements for VANETs applications prove stringent. Thus, fail-safe security is mandatory. However, providing security in vehicular networks raises important privacy concerns also worth considering. Security and privacy are the two main concerns motivating robust vehicular network designs. In this paper, we will discuss some threats and attacks that can be exploited, and in response, present some viable security solutions.

Title: An efficient parallel architecture for ray-tracing
Authors: Alexandre S Nery Nadia Nedjah Felipe M G Franca
Abstract: Real time rendering of three-dimensional scenes in high photorealistic details is a hard task, such as in the ray tracing rendering algorithm. In general, the performance achieved by a sequential software-based implementation of ray tracing is far from satisfactory. However, parallel implementations of ray tracing have been enabling reasonable real time performance, as the algorithm is embarrassingly parallel. Thus, a custom parallel design in hardware is likely to achieve an even higher performance. In this paper, we propose a hardware parallel architecture capable of dealing with the main desirable features of ray tracing, such as shadows and reflection effects, imposing low area cost and a promising rendering performance. Such architecture, called Grid RT, is based on the Uniform Grid acceleration structure and is intended to deliver massive parallelism through parallel ray-triangle intersection tests as well as parallel processing of many rays. A hardware implementation of the proposed architecture is presented, together with some performance results and resources requirements. The rendering is reduced by 80% using a grid configuration of eight processing elements.

Title: A Machine Learning-based Usability Evaluation Method for eLearning Systems
Authors: Asil Oztekin, Dursun Delen, Ali Turkyilmaz, Selim Zaim
Abstract: The research presented in this paper proposes a new machine learning-based evaluation method for assessing the usability of eLearning systems. Three machine learning methods (support vector machines, neural networks and decision trees) along with multiple linear regression are used to develop prediction models in order to discover the underlying relationship between the overall eLearning system usability and its predictor factors. A subsequent sensitivity analysis is conducted to determine the rank-order importance of the predictors. Using both sensitivity values along with the usability scores, a metric (called severity index) is devised. By applying a Pareto-like analysis, the severity index values are ranked and the most important usability characteristics are identified. The case study results show that the proposed methodology enhances the determination of eLearning system problems by identifying the most pertinent usability factors. The proposed method could provide an invaluable guidance to the usability experts as to what measures should be improved in order to maximize the system usability for a targeted group of end-users of an eLearning system.

Title: Bluetooth Positioning using RSSI and Triangulation Methods
Authors: Yapeng Wang, Xu Yang Yutian Zhao
Abstract: Location based services are the hottest applications on mobile devices nowadays and the growth is continuing. Indoor wireless positioning is the key technology to enable location based services to work well indoors, where GPS normally could not work. Bluetooth has been widely used in mobile devices like phone, PAD etc. therefore Bluetooth based indoor positioning has great market potential. Radio Signal Strength (RSS) is a key parameter for wireless positioning. New Bluetooth standard (since version 2.1) enables RSS to be discovered without time consuming pre-connection. In this research, general wireless positioning technologies are firstly analysed. Then RSS based Bluetooth positioning using the new feature is studied. The mathematical model is established to analyse the relation between RSS and the distance between two Bluetooth devices. Three distance-based algorithms are used for Bluetooth positioning: Least Square Estimation, Three-border and Centroid Method. Comparison results are analysed and the ways to improve the positioning accuracy are discussed.
