Real-Time Obstacle Detection Approach using Stereoscopic Images
Статья научная
In this paper, we propose a new and simple approach to obstacle and free space detection in an indoor and outdoor environment in real-time using stereo vision as sensor. The real-time obstacle detection algorithm uses two dimensional disparity map to detect obstacles in the scene without constructing the ground plane. The proposed approach combines an accumulating and thresholding techniques to detect and cluster obstacle pixels into objects using a dense disparity map. The results from both analysis modules are combined to provide information of the free space. Experimental results are presented to show the effectiveness of the proposed method in real-time.

Recommender System in Tourism Using Case based Reasoning Approach
Статья научная
Using recommender systems with the help of computer systems technology to support the Tourist advising process offers many advantages over the traditional system. A knowledge based recommender reasons about the fit between a user’s need and the features of available products. Providing an effective service in Ethiopian Tourism sector is critical to attract more foreign and local tourists. However, there are major problems that need immediate solution. First, the difficulty of getting fast, reliable, and consistent expert advice in the sector that is suitable to each visitor’s characteristics and capabilities. Second, inadequacy of the number of experienced experts and consulting individuals who can give advice on tourism issues in the country. Therefore, this paper aims to design a recommender system for tourist attraction area and visiting time selection that can assist experts and tourists to make timely decisions that helps them to get fast and consistent advisory service. So that, visitors can identify tourist attraction areas that have the highest potential of success/satisfaction and that match their personal characteristics. The system provides recommendation to visitors based on previously solved cases and new query given by the tourist. For this study, about 615 cases which are collected from National Tour operation and 10 attributes which are collected from experts are used as case base. These attributes and cases are used as knowledge base to construct case based recommender. The system calculates similarity between existing cases and new queries that are provided by the visitors, and provide solution or recommendation by taking best cases to the new query. In this study, JCOLIBRI case base development tool is used to develop the prototype. JCOLIBRI contains both user interface which enables visitors to enter their query and programming codes with the help of Java script language. To decide the applicability of the prototype in the domain area, the system has been evaluated by involving domain experts and visitors through visual interaction using the criteria of easiness to use, time efficiency, applicability in the domain area and providing correct recommendation. Based on prototype user acceptance testing, the average performance of the system is 80% and 82% by domain experts and visitors respectively. The performance of the system is also measured using the standard measure of relevance (IR system) recall, precision and accuracy measures, where the system registers 83% recall, 61% precision and 85.4% accuracy.

Redesign Sanjai Chips Packaging Using Kansei Engineering Method
Статья научная
Sanjai chips made from cassava is typical tradisional Minang food. Packaging design is fundamental because 89% of consumer responses to buying a product are influenced by packaging. Current packaging weakness are plastic packaging is thin, no accompanying brands, and unattractive packaging, so less attractive, greasy, leaks, and make the chips contained in it be destroyed when bought for souvenirs. For this reason, it is necessary to redesign packaging for sanjai chips to increase product protection and influence consumers. Kansei Engineering is a method that deals with the psychological aspects of consumers when interacting with products to obtain a relationship between feelings and product characteristics. Because of that, this method has been chosen. The kansei process begins with a span of semantic space which begins with determining the kansei word. Kansei words were obtained from the distribution of open questionnaires and also based on previous research. After that, the span of the space of properties is determined which is useful for identifying what product properties should be in the design. after that the synthesis, design and evaluation are carried out. Based on the results from the results of the synthesis of span of semantic space and span of the space of properties, it was found that to design Sanjai Chips packaging, the criteria for packaging design are simple, good, informative, unique, and convincing for packaging materials must be non-greasy, made of plastic, good, strong, and convincing, while for other facilities criteria must be flexible.

Reducing Multicast Redundancy and Latency in Multi-Interface Multi-Channel Wireless Mesh Networks
Статья научная
In wireless mesh networks, each node can be equipped with multiple network interface cards tuned to different channels. In this paper, we study the problem of collision-free multicast in multi-interface multi-channel wireless mesh networks. The concept of interface redundancy is proposed as a new criterion for the multicast/broadcast redundancy in wireless mesh networks, and we prove that building a multicast/broadcast tree with the minimum interface redundancy is NP-hard. We also prove that the minimum-latency multicasting problem in multi-channel wireless mesh networks is NP-hard. We present two heuristic-based algorithms which jointly reduce the interface redundancy and the multicast latency. Since broadcast can be considered as a special case of multicast, an approximate algorithm for low-redundancy broadcast tree construction is also proposed, which has a constant approximation ratio. Finally, the simulation results prove the effectiveness of our approach.

Reduction of Multiple Move Method Suggestions Using Total Call-Frequencies of Distinct Entities
Статья научная
Inappropriate placement of methods causes Feature Envy (FE) code smell and makes classes coupled with each other. To achieve cohesion among classes, FE code smell can be removed using automated Move Method Refactoring (MMR) suggestions. However, challenges arise when existing techniques provide multiple MMR suggestions for a single FE instance. The developers need to manually find an appropriate target classes for applying MMR as an FE instance cannot be moved to multiple classes. In this paper, a technique is proposed named MultiMMRSReducer, to reduce multiple MMR suggestions by considering the Total Call-Frequencies of Distinct Entities (TCFDE). Experimental results show that TCFDE can reduce the multiple MMR suggestions of an FE instance and performs 77.92% better than an existing approach, namely, JDeodorant. Moreover, it can ensure minimum future changes in the dependent classes of an FE instance.

Reduction of Power Consumption in FPGAs - An Overview
Статья научная
Field Programmable Gate Arrays FPGAs are highly desirable for implementation of digital systems due to their flexibility, programmability and low end product life cycle. In more than 20 years since the introduction of FPGA, research and development has produced dramatic improvements in FPGA speed and area efficiency, narrowing the gap between FPGAs and ASICs and making FPGAs the platform of choice for implementing digital circuits. FPGAs hold significant promise as a fast to market replacement. Unfortunately, the advantages of FPGAs are offset in many cases by their high power consumption and area. The goal is to reduce the power consumption without sacrificing much performance or incurring a large chip area so that the territories of FPGAs applications can expand more effectively. Reducing the power of FPGAs is the key to lowering packaging and cooling costs, improving device reliability, and opening the door to new markets such as mobile electronics. This paper presents the tips to lower down the static and dynamic power dissipation in FPGAs. It gives an overview of various techniques at system, device, and circuit and architecture level used for reduction of power consumption of FPGAs and their outcomes.

Статья научная
With the rapid development of information technology, it is inevitable for the distributed mobile computing will evolve to the pervasive computing gradually and whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Furthermore, with the development of SOA, more and more pervasive applications have been composed of different kinds of services. So how to choose a suitable service from all the useable services is the most important step for pervasive computing. Compare to the traditional service selection we must take more care of the context as well as the quality of them in pervasive environment. However, most of existing researches pay no attention to QoC(Quality of Service) which may lead to unreliable selections. Therefore we proposed a middleware based service selection scheme to support QoC-aware service selection efficiently.

Security Challenges and Attacks in Mobile Ad Hoc Networks
Статья научная
Mobile Ad hoc Network (MANET) is an autonomous collection of mobile nodes that form a temporary network without of any existing network infrastructure or central access point. The popularity of these networks created security challenges as an important issue. The traditional routing protocols perform well with dynamically changing topology but are not designed to defense against security challenges. In this paper we discuss about current challenges in an ad hoc environment which includes the different types of potential attacks that are possible in the Mobile Ad hoc Networks that can harm its working and operation. We have done literature study and gathered information relating to various types of attacks. In our study, we have found that there is no general algorithm that suits well against the most commonly known attacks. But the complete security solution requires the prevention, detection and reaction mechanisms applied in MANET. To develop suitable security solutions for such environments, we must first understand how MANETs can be attacked. This paper provides a comprehensive study of attacks against mobile ad hoc networks. We present a detailed classification of the attacks against MANETs.
