Title:	INVESTIGATION STUDY: AN INTENSIVE ANALYSIS FOR MSA LEADING METHODS
Author:	MUHANNAD A. ABU-HASHEM, NUR'AINI ABDUL RASHID, ROSNI ABDULLAH, AWSAN A. HASAN AND ATHEER A. ABDULRAZZAQ
Abstract:	Multiple sequence alignment (MSA) is a cornerstone process in computational biology and bioinformatics and it is necessary for sequence analysis. Through decades of extensive research to solve the MSA problem, numerous methods have been proposed and developed. Dynamic programming-based methods suffer from the high computational cost in building MSA. Therefore researchers tend to solve MSA problem using heuristic methods as they attempt to reach optimal results in a reasonable time. Progressive alignment method is the most used method for constructing MSA. In this paper we present an extensive analysis for the leading methods and top performing methods in MSA. The leading methods of MSA are discussed individually to highlight the differences in methods and techniques they use beside the progressive alignment. Also, we present a critical analysis for MSA leading methods based on experimental results where BaliBASE database is used as a benchmark. Results show that MSAProbs algorithm has the superior accuracy performance over all leading methods while MUSCLE and Clustal W are the fastest. Although numerous algorithms have been proposed for MSA, producing an efficient MSA with high accuracy remains a huge challenge.
Keywords:	Multiple sequence alignment, MSA leading methods, Progressive alignment, Sequence alignment, Guide tree, and Computational biology.

Title:	BANDWIDTH PROVISIONING SCHEME FOR 3D WIRELESS SENSOR NETWORKS
Author:	MANAL A. MIZHER, SALEH H. AL-SHARAEH, RIZA SULAIMAN, MANAR A. MIZHER
Abstract:	Bandwidth (BW) resources are scarce and valuable in Wireless Sensor Networks (WSNs). Managing this scarcity in BW is a key challenge in WSN's environments. Achieving high BW utilization (BWU) will rise the Quality of Service (QoS) that network can guarantee, without the omission of the importance of concurring BWU, with the minimizing of connection blocking (CBP) and dropping (CDP) probabilities. This paper considers attaining high QoS from point of BW scheduling whether WSNs is designed in two or three dimensions, also our scheme studies the effect of existence or the absence of base station blind spot. We have tested WSN under sixteen different cases, which comprised: Two Dimension structure (2D), 3D structure, Indoor space (Is), Outdoor space (Os), without Blind Spot (nBS), with Blind Spot (wBS), using static borrowing mechanism (SBBS), and finally using dynamic borrowing mechanism (DBBS). The results revealed that considering network with using dynamic borrowing scheme and with rate up to 50 connection rate (CR) will have better QoS guarantees. Moreover, we can summarize that 3D space outperforms 2D space in general view. Finally, not considering BS and building network outdoor will have better QoS guarantee in general. In addition, it is worth mentioning that previous results are processed from repetition each situation 2500 times, which make these results high strict and reliable.

Title:	PERFORMANCE ANALYSIS OF RELAY AND COMBINING METHODS IN WIRELESS NETWORKS
Author:	ABDULJALIL SAIF , MAHAMOD ISMAIL, ROSDIADEE NORDIN AND MOHAMMED FADHIL
Abstract:	The quality signal in a wireless transmission occasionally suffers from severe bad channel quality due to effects like fading caused by multi-path propagation. Diversity is one of the methods that used to reduce such effect whereby different samples of the same signal are transferred over essentially independent channels. Cooperative wireless communication it resolves this problem by transmitting a message to a destination with the assistance of a relay. Upon receiving the message from the transmission source, the relay retransmits the message to the destination. Therefore, the combination of the direct and relay transmissions, improves signal reception at the receiver whereby the signal is clearer and better. As such, this paper compares and evaluates the performance of different relays and combining methods in cooperative relay network under noisy and Rayleigh fading channel. This paper examines the Amplify and Forward (AAF) and Decode and Forward (DAF) relay protocols using Maximal-Ratio Combining (MRC), Fixed-Rate Combining (FRC) and Equal-Rate Combining (ERC) methods with BPSK and QPSK modulation based on simulations. The result of the simulations, show that AAF performs better than DAF in terms of Bit Error Rate (BER) without the introduction of error correcting code. Another finding reveals that the relative distances between the relay and the stations affect the performance of BER. The unique of this work is, presented different combining methods with different distance channels between users, distention and relay using different modulation technique. The best performance is achieved when the relay is located in the middle between the source and destination. Finally, the combination of FRC and BPSK shows the best BER performance for SNR up to 20 dB.

Title:	BUILDING A SYSTEM WITH NO SQL APPROACH (CASE STUDY: ENGLISH WRITING APPLICATION)
Author:	Tanty Oktavia , Surya Sujarwo
Abstract:	As the complexity of business process, the need for implementing information systems also grows. A number of companies have built sophisticated system to fulfill operational. To maximize the benefit of the system, the data has to be stored in database for long time period so it can be used for analysis in the future. There are many models Database Management System (DBMS) architecture that can be applied, one of them are NoSQL architecture. NoSQL and relational model are two models that are very different. Relational model concept store data in the table, which consists of column and row. Each table interconnected by using foreign key (FK) which is an attribute. When the developer wants to consolidate data from all existing table, then the developer must combine a table with another table, through a foreign key that has defined in the first time, so it can certainly be combined data. Nowadays it’s often be problem for a developer, given the massive data growth, with a fairly high degree of scalability that will be very difficult for a developer to provide the required data in a short time. Therefore, NoSQL approach comes as a solution. In NoSQL, data will be stored in the form of documents and data integration will be done using programming language format. Each document can be likened to a programming language object that can be used in applications that are built. So that access to the data can be done efficiently and effectively despite the huge amount of data. In this research focuses on implementation NoSQL in English Writing Application based on JavaScript Platform.

Title:	X-TRACT RECODING ALGORITHM FOR MINIMAL HAMMING WEIGHT DIGIT SET CONVERSION
Author:	MIZA MUMTAZ AHMAD, SHARIFAH MD YASIN, RAMLAN MAHMOD, MOHAMAD AFENDEE MOHAMED
Abstract:	Scalar multiplication is the most computational intensive operation in elliptic curve cryptosystem (ECC). Improving the performance of this operation can be achieved by using recoding technique which aims at minimizing the density of nonzero digits in the scalar, also known as its Hamming weight. We proposed X-Tract recoding technique that alters the representation of scalar from binary digit to {-1,0,1,3} digit set in non-adjacent form (NAF). The recoding algorithm can be expressed both mathematically and logically and reduces the Hamming weight of the scalar to 41% in average for 163-bit scalar with balanced bit. X-Tract Recoding algorithm reads every three adjacent bits overlapped by one bit from left-to-right in the input binary scalar to produce each new output digit. We use ANOVA analysis to show that the new recoding technique produces significantly better output with less Hamming weight compared to its counterparts.
