Title:	DOCUMENT SIMILARITY DETECTION USING SYNONYMS FACTOR AND PARALLEL PROCESSING
Author:	KEMAL ADE SEKARWATI, LINTANG YUNIAR BANOWOSARI, I WAYAN S. WICAKSANA, ANA KURNIAWATI
Abstract:	Research regarding Indonesian language document similarity measurement has not yet broad to do. Mostly those researches using Karp Rabin algorithm and string matching method, and the documents used in the form of abstracts and articles which only has one page. This study focused on measuring similarity detection of Indonesian language documents using synonyms factor for more than one page document and the processing speed measurement. The system developed is to measure the similarity of existing documents with other documents that are stored in an internal database. Similarity calculation results in the form of a percentage of the document similarity comparison. The measurement results of document processing speed in the form of speed detection in processing the documents. The calculation of the similarity detection measurement and its detection speed is performed using the following steps: (i) examine the documents title, (ii) Distribution of work, (iii) the document similarity measurement and (iv) speed measurement of document similarity detection process. Tests carried out using Indonesian documents that are larger than one page. Documents that have been tested were 15 documents. Test results to calculate document similarities and detection speed conducted on four types of documents. This study has shown that the algorithm used can check the similarity of documents with the maximum number of pages is 56 pages. From the speed of the detection process shows that the speed measurement in detection process algorithm is also said to be successful.

Title:	EDGE DETECTION ALGORITHM FOR COLOR IMAGE BASED ON QUANTUM SUPERPOSITION PRINCIPLE
Author:	DINI SUNDANI, A. BENNY MUTIARA, ASEP JUARNA, DEWI AGUSHINTA R
Abstract:	Edge detection is first stage of image analysis. Edge can produce information of an image used for pattern recognition or image retrieval. A problem encountered in the process of edge detection is the edge was not detected properly. This happens because the color image was being transformed into gray image. The development of method or edge detection algorithms has been carried out with the aim to obtain a clear and perfect edge. However, the development of algorithms performed by classical computing, where data is calculated in parallel. This paper proposed a development of edge detection algorithm on color images with transformation into gray image and without transformation where data is processed at each channel based on the RGB color space. Both are done based on the principles of quantum superposition. Superposition is one of the properties owned in quantum computing, where data can be calculated simultaneously which is the probability of the states. Stages of research are initiated by image enhancement to reduce noise or get a smoothing area. The second stage is to determine superposition of edge strength (magnitude value) using Sobel operator. The last stage is the edge localization to determine the exact location expressed as edge or to detect the edge where the detected edges must be close as the actual edge.

Title:	TRANSACTION LEVEL MODELS’ STRUCTURING: FROM IDIOMS TO TLM-2
Author:	SALAHEDDINE HAMZA SFAR, IMED BENNOUR, RACHED TOURKI
Abstract:	A system on chip (SoC) designing cost is not only dependent on the manufacturing process but also on the used design methodologies and tools. Transaction level modelling (TLM) has emerged as an efficient methodology of electronic system level (ESL) design, with an acceptable simulation speed and modelling accuracy. During the last decade, the research efforts were to define the various TLM abstraction levels, TLM taxonomies, and TLM programming languages. The result was the definition and the standardization of the SystemC language, the TLM-2 library and a set of coding styles. The further step toward an efficient TL modelling methodology consists in structuring the various TL models. This paper firstly reviews the most important steps in the evolution of the TLM methodology and secondly it presents an efficient structuring of the TL models based on TLM-2 library.

Title:	OPTIMIZATION OF DEVICES AND LIGHT COUPLING BASED ON PHOTONIC BIDIMENSIONNELS CRYSTALS
Author:	RACHIDA. HEDARA, AICHA. FLITTI, DJAMEL-EDDINE. KALAIDJI
Abstract:	The research high lights the value of using photonic crystals for integrated optics. These materials, whose dielectric constant varies periodically across the wavelength, have the particularity to present photonic bandgap prohibiting light propagation in the structure. The use of this effect bandgap opens the way for the realization of many optical functions such as guide. Usually the guide in photonic crystals is accomplished by creating the linear defects in the lattice constant. Our studies were conducted largely through simulations using executable 2D FDTD software. The choice of the FDTD numerical method (Finite- Difference- Time- Domain) is due to its universality and its simplicity of the use and the implementation. To know the spectral response of this type of periodic as well as field distributions in structures of finite dimensions system, we used the most common 2D FDTD numerical method.

Title:	SOFTWARE TAMPERING DETECTION IN EMBEDDED SYSTEMS – A SYSTEMATIC LITERATURE REVIEW
Author:	ABDO ALI ABDULLAH AL-WOSABI, ZARINA SHUKUR
Abstract:	Embedded systems (ES) become available anywhere and anytime as an established part of our daily routines. Their usage in sense, store, process, and transfer our personal and private data, such as ATM card, modern cars system, mobile phones, and etc., become irreplaceable. Developers of these systems face significant challenges in code and information security. Whereas, software tampering is one of these challenges, code integrity detection is one of the main approaches used to defeat it. Checking code integrity achieves tamper proofing by method of identification of unauthorized alteration to recognize any tampered code is executed or tampered data are used. For the purpose of this paper, we perform a research methodology based on systematic literature reviews in-order to present different techniques/approaches of code integrity checking in embedded systems. We briefly survey a number of research studies (specifically between 2008 and 2014) related to this issue and present their proposed solutions. Obviously, there is no complete solution, and our aim by conducting this review is to contribute (even a modest effort) on fighting against software tampering.

Title:	RACARP: A ROBUSTNESS AWARE ROUTING PROTOCOL FOR COGNITIVE RADIO AD HOC NETWORKS
Author:	ZAMREE CHE-ARON, AISHA HASSAN ABDALLA, KHAIZURAN ABDULLAH, WAN HASLINA HASSAN, MD. ARAFATUR RAHMAN
Abstract:	Cognitive Radio (CR) is a new paradigm which offers a viable solution to deal with the spectrum shortage problem and enhances the spectrum utilization in wireless communication systems. In Cognitive Radio Ad Hoc Networks (CRAHNs), data routing is one of the most challenging tasks due to varying link-quality, frequent topology changes and intermittent connectivity caused by the activities of Primary Users (PUs). This paper proposes a robustness aware routing protocol for CRAHNs, referred to the Robustness Aware Cognitive Ad-hoc Routing Protocol (RACARP), with an aim to provide robust transmission path and offer fast route recovery in presence of PU activities during data delivery. The Expected Path Delay (EPD) routing metric used in the protocol for path decision is also introduced. The protocol avoids creating a transmission path that uses PU’s channel in PU regions in order to counteract the impact of PU activity. Moreover, for the purpose of fast route recovery, the multi-path multi-channel routes are given by utilizing the joint path and spectrum diversity in routing. The performance evaluations are conducted through simulations using NS-2 simulator. The simulation results obviously demonstrate that the RACARP protocol can significantly achieve better performance in terms of average throughput, packet loss, average end-to-end delay, and average jitter as compared to the recently proposed D2CARP protocol in identical scenarios.

Author:	P. MICHAEL PREETAM RAJ, HARI KISHORE KAKARLA, RAKESH TIRUPATHI, P.SALEEM AKRAM, T.ANJI REDDY
Abstract:	Automatic water pumping system is extremely required for effective usage of water resources in various areas such as irrigation for crops. In this paper, an Automatic Irrigator (AI) system which can save water wastage by controlled water pumping thus provides very high energy efficiency is presented. The system has its ability to automatically control the turning on and off of the motor, based on the water level, thus maintaining a controlled water level. The stunning feature of this system can be to provide solutions for the varying water requirements of the crops at different stages during the growth process by considering a micro-controller based approach to automatically maintain the varying levels of waters as per requirements. Also several other applications of this proposed system exists such as water level control in water tanks, maintaining ground water level, etc., thus usable for multiple applications, by making slight modifications to the system. The proposed system based on EDR201A05 makes use of only a single 5V DC supply to control, based on the conductive property of water, a motor which can pump water. The proposed system is also extremely attractive because of its simplicity, controllability, and low cost. This system can also automatically sends the pumping motors into idle state during rainy days saving power and water.
