1. RECONSTRUCTION OF LATTICE-LIKE OBJECTS ON MOBILE DEVICES

Authors: THOMAS HUNZIKER

Abstract: Smart phones and tablet computers are typically equipped with a camera and a powerful processor, and together with the right computer vision software they can support engineers and other professionals in a broadrange of tasks. Creating 3D models of real world objects is one job that can be very time consuming for humans if carried out manually, whereas with an adequate image processor the task can be completed very efficiently. In this paper we focus on the recognition of lattice-like objects made up of elements from a certain set of basic components. We propose a procedure incorporating a 2D detection of object parts, a 3D reconstruction, and a 3D model composition. The efficiency of the procedure is demonstrated by means of a prototype in the form of an Android app, accomplishing a 3D recognition and rendering of molecular models.

3. ON THE SCALABILITY OF SIMULATING CLOUD SYSTEMS

Authors: ALBERTO NUNEZ , MANUEL NUNEZ , MERCEDES G. MERAYO , SERGIO NUNEZ

Abstract: Simulation of cloud computing systems remains to be a challenge due to the high number of issues that hamper this task. Basically, the main issue for achieving simulations of cloud systems is two-fold. First, the enormous amount of time required to execute those simulations. Second, the large amounts of memory required for simulating the high number of elements that constitute the model. In most cases, those systems contain thousands of computing nodes, tens of storage nodes, communication networks, and communication switches, whereof the algorithms required for modelling and simulating all those elements require huge amounts of CPU power. In this paper we present a complementation for INET, a framework used for modelling and simulating networks in cloud systems models.

5. POST-DISASTER RESOURCE MANAGEMENT USING PEER-TO-PEER OPPORTUNISTIC NETWORKS

Authors: DEBANJAN DAS DEB , SOMPRAKASH BANDYOPADHYAY

Abstract: During large-scale disasters, it is often found that services that are relied for everyday communications become non-functional. This becomes a barrier and a key challenge in effective transmission of information related to the disaster through electronic media in executing relief operations. In these situations, portable devices like the smart phones come in handy and are effective in storing offline information during post disaster management operations. Effective utilization of these mobile databases through coordination will provide a platform for executing disaster relief operations. In this paper, we have proposed a scheme in which a virtual opportunistic network is formed by these mobile agents, that effectively addresses the resource management and post disaster relief operations. Through direct and indirect coordination between agents in those situations, different static nodes in an area will become aware of the geographical location of other nodes. Aggregation of such struct

6. A PARALLEL IMPLEMENTATION FOR GRAPH PARTITIONING HEURISTICS

Authors: LEONARDO ROGERIO BINDA DA SILVA , RONEY PIGNATON DA SILVA

Abstract: The Graph Partitioning Problem (GPP) has several practical applications in many areas, such as design of VLSI ( Very-large-scale integration) circuits, solution of numerical methods for simulation problems that include factorization of sparse matrix and partitioning of finite elements meshes for parallel programming applications, between others. The GPP tends to be NP-hard and optimal solutions for solving them are infeasible when the number of vertices of the graph is very large. There has been an increased used of heuristic and metaheuristic algorithms to solve the PPG to get good results where exceptional results are not obtainable by practical means. This article proposes an efficient parallel solution to the GPP problem based on the implementation of existing heuristics in a computational cluster. The proposed solution improves the execution time and, by introducing some random features into the original heuristics, improve the quality of the created partitions.

7. THE USE OF ARTIFICIAL INTELLIGENCE IN COGNITIVE DECISION MAKING – A REVIEW

Authors: V. PRAVEEN KUMAR , V.S.S KUMAR

Abstract: Many problems of the real world vary with number of parameters affecting the system and their computations become a difficult task. Artificial neural networks (ANN) can learn and be trained on a set of input and output data belonging to a particular problem. The field applications of Artificial Intelligence have increased dramatically in the past few years. ANN is built from a large number of processing elements that individually deal with pieces of a big problem. If new data of the problem are presented to the system, the ANN can use the learned data to predict outcomes without any specific programming relating to the category of events involved. A large variety of possible ANN applications now exist for non ¬computer specialists. Therefore, with a very modest knowledge of the theory behind ANN, it is possible to tackle complicated problems in a researcher's own area of specialty with the ANN techniques. ANN learning occurs through training to a set of input and output data, where the

8. SOFTWARE INTERNATIONALIZATION : INCORPORATING USERS’ TRANSLATIONS

Authors: JAUHAR ALI

Abstract: Internationalized software, which support localization by allowing users to choose the user interface language of their choice, has a lot wider audience than a single-language software. Providing resource files for multiple languages is expensive and not scalable for large number of languages. This limits the availability of software products to only those communities who speak major languages. In this study, we investigate the idea of allowing users to create user interface translation of software and share them with other users. We believe that such an approach is scalable as it does not incur any extra cost.

10. ROUND OFF ERROR PROPAGATION IN SIMULATION OF RC CIRCUIT SUBTITLE : SIMULATION OF RC CIRCUIT

Authors: SHREYAS FADNAVIS

Abstract: Electrical devices often use RC, LC or RLC circuit to design power amplifiers, filters and mixers etc. Complex iterative algorithms are used for the simulation of these circuits. . This paper illustrates numerical experiments on growth of rounding off error in simulation of simple RC circuit using fourth order Runge-Kutta method (RK) and the Runge-Kutta-Fehlberg with adaptive step size control method (RKF). Our analysis indicates that in simulations with RK method, round off error grows ~ 80% with 10-15 iterations and ~96-98% within 100 iterations with different step sizes and double precision. In the simulations with RKF method round off error grows to 70% with 10-20 iterations and ~80% within 100 iterations. It does not exceed 80% for 1000 of iterations for single and double precision. This indicates that growth of round off error in RKF method is less and it should be used to minimize round off error.

Authors: K.S.GURUMURTHY , K.S.GURUMURTHY

Abstract: Power is a major design constraint for low power applications. Its consumption during the execution of the software program is an important issue in designing low power embedded devices. This so called software power can be reduced in many ways. By manipulating the instructions in a code, software related power could be reduced. This work brings about the efficient scheme for instruction level software power analysis for TMS320C6713 DSP processor. This is achieved by measuring the average instantaneous current drawn and hence power dissipated by the processor as it repeatedly executes the set of instructions.

Authors: K.S.GURUMURTHY , PRAMEELA KUMARI N

Abstract: Shockley’s transistor invented in 1952 has shrunk immensely as the years pass by, making the electronic computers very compact and one of the most powerful devices of the century. However advancements in Microelectronics as per Moore's law, face huge technical barriers in the future of transistor based computation due to the limitations posed at the nanoscale size. In view of this the International Technology Roadmap for Semiconductors (ITRS) has indicated several new technologies that are likely to replace the transistor based computation in the near future. Some of these include Resonant Tunneling Diodes (RTDs), Single Electron Tunneling (SET), Quantum Cellular Automata (QCA), and Tunneling Phase Logic (TPL). Among these, QCA seems to be the most promising emerging technology, as a viable alternative to CMOS. In this paper an effort has been made to present the review of the work carried out in QCA till date, from the time of its invention in 1940.

Authors: JIRAPUN DAENGDEJ , MOHAMMAD RAVA

Abstract: Test Case reuse is known as a prominent solution for reducing the cost of testing while increasing the test reliability and productivity. There are many methodologies presented that concentrate on generating reusable test cases, however there are very few that concentrate on measuring how reusable a test case is based on internal and external characteristics. This research investigated several metrics for measuring test case reusability and selected two that were most prominent. The two metrics are then combined and result a measurement model for measuring test case reusability. The prominent characteristic of this model is that it can serve as a template for test case reusability as it will allow for further metric factors to join and expand upon it.

Authors: AYOOB A.AYOOB , GHAIDAA M. ABDULSAHIB , MUAMER N. MOHAMMED , NORROZILA SULAIMAN , OSAMAH I. KHALAF

Abstract: Many routing protocol methods have been proposed in Mobile Ad-Hoc Network but still the challenges are to improve the routing performance. In small or medium ad hoc networks flat protocols can be used but in case of large networks more complicated routing protocols are needed to be used in order to be suitable with them. Since the Ad-hoc networks have many constrains in bandwidth and battery life so the routing protocol which is used must be done its work correctly without using much resources of network by its overhead traffic. This paper, focus on investigation the performance analysis of four important routing protocols in mobile Ad hoc networks such as AODV (Ad- Hoc On-Demand Distance Vector), DSR (Dynamic Source Routing Protocol), DSDV (Destination Sequenced Distance-Vector), and OLSR (Optimized Link State Routing Protocol). The analysis of performance is made on QoS parameters such as the basis packet delivery ratio, throughput, and end-to-end delay, the simulator used is NS-2.

20. A PHYSICAL MEASUREMENT-BASED SYBIL NODES DETECTION MECHANISM IN VANETS

Authors: JOOSEOK SONG , DONGXU JIN , FEI SHI

Abstract: In traffic safety applications of Vehicular Ad-hoc Networks (VANETs), security is a very important issue. Sybil attack is a particular attack where the attacker illegitimately claims multiple identities. In the past, several approaches have been proposed to solve this problem. They are categorized into PKI-based, infrastructure-based, observer-based, and resource-testing-based schemes. In this paper, existing protocols are analyzed, and a novel scheme for detecting the Sybil nodes in VANETs is presented, reducing the effect of a Sybil attack. The proposed Sybil nodes-detection scheme, Physical Measurement-Based Sybil Nodes Detection Mechanism in VANETs (PMSD), takes advantage of physical measurements of the beacon message instead of key-based materials, which not only solves the Sybil attack problem, but also reduces the overhead of detection. The proposed scheme has no fixed infrastructure, which makes it easier to implement. The simulation results show a 95% detection rate of Sybil n

22. A RFID YOKING PROOF PROTOCOL TO PRESERVE AN OFFLINE VERIFICATION USING THE COMMITMENT DISCLOSURE

Authors: JOOSEOK SONG , HYOUNGMIN HAM

Abstract: A RFID (Radio Frequency Identification) yoking-proof provides a verification manner that a pair of RFID tags is scanned simultaneously by one reader device to guarantee the physical proximity of multiple objects. However, the previous studies provide the verification that requires the online verifier. The connectivity between a reader and a verifier limits the practicality of a yoking proof. In this paper, we propose an offline yoking proof protocol to preserve the offline verification that does not require the online verifier. In addition, the protocol for a pair of tags is easily extended to the one for multiple tags without additional expensive devices. Our analysis shows that the proposed protocol provides offline verification securely and effectively.

23. CLASSIFICATION OF CLUSTERING SCHEMES IN VANETS

Authors: JOOSEOK SONG , INHWAN KIM

Abstract: The emergence of Vehicular Ad-hoc Networks (VANETs) provides drivers and passengers with safer and more convenient services. However special characteristics of VANETs such as high mobility, movement constraint, and signal blocking hinder the wide propagation of it. One good way to alleviate those unique characteristics of VANETs is clustering. Even though there are many clustering techniques, few investigations to understand them are conducted. In this paper, we examine some cluster based approaches in VANETs carefully and classify them into two categories based on the property of cluster; that is, stationary cluster and mobile cluster. Finally, the advantages and disadvantages of both will be illustrated. We hope that researchers who design the new clustering mechanism in VANETs could facilitate this classification to make theirs more suitable for their purpose.

Authors: ASIM R. ALDHAHERI , ERAN A. EDIRISINGHE

Abstract: In this paper we present a new method for detecting and classifying moving objects into humans and vehicles from a video surveillance scene. In this approach, the moving objects are firstly detected from the background using a background subtraction technique. Background subtraction algorithms are implemented in a MATLAB environment. A comparison for all the algorithms was made to determine which background subtractionalgorithm performs better with the proposed classifying algorithm. The algorithms were then tested using more than a video and many frames of the video was tested. Secondly, edge detection of moving objects was performed using Canny or Prewitt operations, while bounding boxes were implemented over the moving objects. Edge detection and bounding boxes were used before the classification step to simplify the classification.Finally, classifying the moving object into humans and vehicles was accomplished by finding the height-width ratio of the bounding box around the moving

Authors: JAEHO CHOI , SCOTT UK-JIN LEE

Abstract: HTML5 is not a new version of the existing mark-up language, but a new paradigm for developing web and mobile applications where various new concepts are introduced to improve compatibility and usability. Web-Storage is the one of new features in HTML5 that enables effective client-side storage and retrieval of the frequently used data. However, it has significant security problems which need to solve for providing safe web and mobile environment. Currently, there is lack of analysis and research to detect and prevent attacks on web storage and this can causes critical security threats to web and mobile application developed using HTML5. In this paper, we are going to practically study and analyze possible attacks on web storage as a first step towards ensuring the safety of web and mobile applications based on HTML5.

Abstract: With the rapid growth of reviews, ratings, recommendations and other forms of online expression, online opinion has turned into a kind of virtual currency for businesses looking to market their products, identify new opportunities and manage their reputations. Sentiment analysis extracts, identifies and measures the sentiment or opinion of documents as well as the topics within these documents. The Naïve Bayes algorithm performs a boolean classification i.e. it classifies a document as either positive or negative according to its sentiment. We have already seen by Sayeedunnisa et al [1], that the application of Naïve Bayes trained on high value features, extracted from a bag-of-words model, yields an accuracy of 89.2%. This paper studies the application of Naïve Bayes technique for sentiment analysis by including training of bigram features to improve accuracy and the overall performance of the classifier. We also evaluate the impact of selecting low vs. high value features, calculated

Authors: A. MASOUMI VERKI , M. RASTEGARAN , S. B. BEHESHTI AVAL

Abstract: The collapse probability of structures is determined through two approaches of probability of exceedance in terms of EDP-Based and IM-Based approaches. Pertaining to characteristics of structure and types of excitations, these two values may evaluate the probability of collapse in lower and upper estimation. In this study, through combining these two estimations, a precise measure of collapse probability is exhibited. To evaluate collapse capacity of structures and implementation of probabilistic scheme in structure performance assessment, incremental dynamic analysis (IDA) and fragility curves are used. The systematic view of two approaches of collapse probability consists of engineering demand (EDP-Based) and intensity measure (IM-Based) are considered in series forms. The study results show that the combination of these two aforementioned schemes exhibit comprehensive vision of collapse probability of structures which are very important in performance evaluation of structures.

Authors: BIMAL SARANGI , S. C.PANIGRAHI

Abstract: Production of particle reinforced composites is still in the development stage and investigations are in progress to devise techniques to uniformly distribute the reinforcing particles in the matrix so as to get the best properties. The cause of non-uniform distribution is the density difference and non-wetting behavior of the liquid metal and the particles. Random rotation of the mold is used in the present study to distribute redmud particles in an aluminum matrix. Red mud is a waste produced in the production of alumina and unless disposed properly cause environmental problems. A laboratory ball mill used for mineral processing was modified to suit the requirement. The castings were made in the ball mill with the molds rotating randomly. The microstructure of the samples showed uniform distribution of particles in the matrix. Variants in the mold designs tried and microstructures obtained are reported in the paper. It is observed that upto 25% of redmud can be added to aluminium suc
