Title:	LOSSLESS IMAGE COMPRESSION METHOD USING REVERSIBLE LOW CONTRAST MAPPING (RLCM)
Author:	HENDRA MESRA, HANDAYANI TJANDRASA, CHASTINE FATICHAH
Abstract:	This research introduces a new lossless image compression method by a transform function named a Reversible Low Contrast Mapping (RLCM). This function was successful to be implemented as a reversible watermarking method. This proposed method divides an image into fixed-size blocks and groups the blocks into watermark blocks and host blocks. Furthermore, the watermark blocks are embedded in the host blocks. The proposed method does not use any other lossless compression method in its algorithm. Nevertheless, the proposed method can still be combined with other methods. On all the testing images, the compression ratio of the proposed method achieves 1.19 on average. As a comparison, the Huffman compression ratio is 1.08. By combining the method using the Differential coding and the Golomb encoding, the compression ratio of the proposed method increases to 1.32 on average.

Title:	A NEW STRUCTURAL SIMILARITY MEASURE FOR CLUSTERING MULTI-STRUCTURED DOCUMENTS
Author:	ALI IDARROU, DRISS MAMMASS
Abstract:	Traditional methods of document comparison are based on the similarities called "surfaces": a model of similarity based on descriptive properties of objects without considering the relationships between these properties. We have proposed a new structural measure, based on sub-graph isomorphism, taking into account the distribution (order, position, etc) of components of the documents compared and the relationships between these components (preserve more sense). Our measure reflects both the contextual and structural aspects of documents compared. In this work, we will show in detail our similarity measure and study the impact of the similarity threshold (a parameter fixed previously) on generated clusters. We evaluate our approach on a corpus of multimedia documents extracted randomly from the INEX 2007 corpus and the corpus of descriptive records of books in XML format from the library of the University of Toulouse 1 Capitole.

Title:	INVESTIGATION ON THE EFFECT OF USER’S EXPERIENCE TO MOTIVATE PLAYING ONLINE GAMES
Author:	RYAN RANDY SURYONO, APOL PRIBADI SUBRIADI
Abstract:	Internet technology has been growing and become one of the options for people to interact with others. Now days, one of the most famous usage of the internet was as an entertainment. Online game was a sample. For this reason, therefore the online business games also growth among the public. As someone frequently play the online games, interaction with other users could increase, which would lead for more users to join the game’s community. In this community, users might perform specific roles (role-playing), social interaction and exchange of information. People who did interaction can create their own virtual world. This was a new phenomenon in the human life among gamers. Meanwhile, previous studies have not been sufficient to explain the question why did people tend to play the games, entry to the virtual world, and brought it to the real life. The aims of this study was to find out the motivation that drives someone to play the game. This study also find out the effects of experiences and user interaction as motivation to play online games. Furthermore, Massively Multiplayer Online Role-Playing Games (MMORPG) was chosen as an object. The method of research proposed was qualitative study. The result of research could show that it was very important to know the deeper effect on the attitudes of players typologies constructed when people play the game. This typology could explained the motivation of people for playing games.

Title:	ESTIMATION OF THE DEGREE OF SIMILARITY OF SENTENCES IN A NATURAL LANGUAGE BASED ON USING THE LINK GRAMMAR PARSER PROGRAM SYSTEM
Author:	YERIMBETOVA A.S., MURZIN F.A. , BATURA T.V. , SAGNAYEVA S.K., SEMICH D.F., BAKIYEVA A.M
Abstract:	Our main goal is to construct the algorithms that can estimate the document relevance on the basis of the text structure analysis. It is important that this estimate should be based on the context of the search query and not limited only by keywords, their similarity or frequency. The semantic-syntactical relations between words built by the program system Link Grammar Parser (developed in Carnegie Mellon University, USA) can be used to solve these problems. They allow us to develop the methods of comparison of the sentences in a natural language and introduce certain measures of the closeness (similarity) between the sentences. These measures take into account both lexical and syntactic relations between words. Experiments with different types of sentences and links took almost one year. It was observed that there is no need to use too many links. First, the use of some links leads us to the analysis of diagrams which correspond badly to intuition and principles of classical linguistics, and it is not clear what we can do with them further. Second, there is also a complexity aspect. If there are fewer links, the algorithm works faster. Therefore, a compromise is necessary. The minimum variant giving good results is when only eight connectors (links) are used. One of the problems we solve in the current time is the development of a parser like Link Grammar Parser for Turkic languages most frequent in the Internet, such as Kazakh, Uzbek (Cyrillic and Roman alphabets), and Turkish. The results of our research are planned to be used in different information retrieval systems.

Abstract:	The article describes the issues of building models of documentary and factographic search in multilingual scientific and educational information systems, working with documents of rather free structure. A model of information system document classification is proposed based on the use of tolerance relation, taking into account possible absence of a priori defined classifiers. Particular attention is paid to formation of feature space, taking into account the morphology of the document language. The article contains an overview of morphological text analyzers that can be used to determine the normal form of word. The features of application of morphological analyzers are described; their advantages and disadvantages are listed. The rules for normalization of words of the Kazakh and the algorithm to handle both vocabulary and non-vocabulary (including non-existent) words are developed. A multilingual thesaurus of scientific and technical concepts (terms) on information technology in English, Russian and Kazakh is developed. The system of term normalization and interlingual compliance is implemented for it.
Keywords:	factographic search, educational information systems, document classification, tolerance relation, morphology, morphological text analyzers.

Abstract:	Medical Ultrasound Imaging is a rapidly growing allied field of Imaging Technology which is widely used around the world for diagnosis by clinicians. Non ionizing radiation is what makes ultrasound imaging safe for non-invasive imaging of human tissues. However, visual quality of ultrasound images poses a challenge for the medical practitioner due to multiple reflections of ultrasound signals. Numerous attempts have been made previously to improve the visual quality of the ultrasound images. The paper presents a novel, structured visual quality improvement mechanism based on daubechies (db) wavelet transform. In the proposed methodology, the segmentation of the ultrasound medical image is carried out with the help of active contour technique. The segmented image and the original image are transformed into wavelet domain. Selected wavelet coefficients are combined to improve the visual quality in terms of contrast and edges enhancements. Visual quality enhancement is emphasized with experimentation on medical ultrasound images obtained from AMMA Hospital radiology scanning center in India. Usefulness of the proposed algorithm is judged against denoising algorithms such as empirical mode decomposition (EMD), linear filtering (LF), median filtering (MF), wiener filtering (WF), wavelet based hard and soft thresholding and wavelet block based soft and hard thresholding. Visual quality metrics computed are peak signal to noise ratio (PSNR), normalized cross correlation (NCC), edge strength (ES), image quality index (IQI) and structured similarity index (SSI). Simulations demonstrate that the proposed enhancement algorithm outperformed the existing de-noising algorithms, instigating for actual medical application.

Title:	APPLICATION OF NEURO-FUZZY METHOD FOR PREDICTION OF VEHICLE FUEL CONSUMPTION
Author:	RAMADONI SYAHPUTRA
Abstract:	This paper presents the application of neuro-fuzzy method for prediction of vehicle fuel consumption prediction. Prediction motor vehicle fuel consumption has become a strategic issue, because it is not only related to the issue of availability of fuel but also the problem of the environmental impact caused. This study used automobile data, i.e. number of cylinders, displacement, horsepower, weight, acceleration, and model year, while the output variable to be predicted is the fuel consumption in MPG (miles per gallon). 'Weight' and 'Year' are selected as the best two input variables. The training and checking errors are getting distinguished, indicating the outset of overfitting. The results of this research are expressed in three dimension input-output surface graph of the best two-input ANFIS model for MPG prediction. It is a nonlinear and monotonic surface, in which the predicted MPG increases with the increase in 'Weight' and decrease in 'Year'. The training RMSE is 2.767; the checking RMSE is 2.996. The greater the weight of the motor vehicle, the greater the amount of fuel needed to travel the same distance. In comparison, a simple linear regression using all input candidates results in a training RMSE of 3.453, and a checking RMSE of 3.445.

Title:	MODIFIED DYNAMIC NETWORK SELECTION ALGORITHM FOR HETEROGENEOUS OVERLAID NETWORKS
Author:	V.BHARATHI, L. NITHYANANDAN
Abstract:	To meet wide expectation and growing demand of mobile users, operators have started to deploy different overlapping radio access network technologies. In heterogonous overlaid networks, network selection decision is delegated to mobile users to avoid processing and signaling overhead. In user centric network selection, users select the network selfishly to maximize their utility and cause undesirable network states. Selecting optimal network to meet user experience with enhancement in network performance under dynamically varying network environment is a real challenge. The existing online dynamic network selection algorithm (DNSA) selects network only by considering change in user demand type to meet user experience. Network assisted selection is another existing algorithm which selects network based on dynamic change in network state and improves network performance. In this paper modified dynamic network selection algorithm (m-DNSA) is proposed which learns network state using Boltzmann-Gibb’s reinforcement algorithm, dynamic change in user demand type using Markov Decision Process and selects optimal network. The m-DNSA also considers cost of handover between different networks for selecting network. Hence, it jointly improves performance of network and user experience. The proposed algorithm is investigated in UMTS-WiMAX-WLAN overlaid networks with different type of services and various economical categories of users. Simulation results show that the proposed m-DNSA improves QoS of the users and also increases throughputs of individual network compared with existing DNSA.

Title:	A NEW TOMOGRAPHIC BASED KEYPOINT DESCRIPTOR USING HEURISTIC GENETIC ALGORITHM
Author:	S.HADI YAGHOUBYAN, MOHD AIZAINI MAAROF, ANAZIDA ZAINAL, MAHDI MAKTABDAR OGHAZ
Abstract:	Keypoint descriptor is a fundamental component in many computer vision applications. Considering both computational complexity and discriminative power, SURF descriptor among non-binary and BRISK among binary descriptors are the prominent techniques in the field. Although, these descriptors have shown remarkable performance, but they are still suffering weaknesses such as lack of robustness against image transformations and distortions, especially blur, JPEG compression and lightening variation. To address this matter, a new and robust keypoint descriptor is proposed in this research which is adapted from Tomographic-Image-Reconstruction technique. Convolution of associated image patch and predefined Gaussian smoothed sensitivity maps yield a matrix whose entities demonstrate the average intensity of the pixels at the convolved pixels in the image patch. The initial descriptor vector is built by calculating the absolute differences of all possible pairs of matrix. Then, the most discriminative features of this initial descriptor vector are detected by Heuristic Genetic Algorithm (GA). The Experimental result showed that proposed keypoint descriptor outperformed some existing techniques especially in blur, JPEG compression and illumination variation while it has reasonable performance in other image transformations.
