Synchronization of Data Between SQLite (Local Database)
and SQL Server (Remote Database)
--Showkat Ahmad Dar and Jan Iqra
Dynamic interactive web applications have a database located on cloud or bigger physical servers for data operations and the modern need is the android or smart applications for such dynamic interactive applications. Development of android applications needs a local database within the application that should be synchronized with the main database later. SQLite is one of the reputed databases for android applications and is based on relational model. This paper aims at the development of synchronization tier of SQLite database that synchronizes the data between local database (SQLite) and SQL server located on physical servers using the concept of web services.

Computer-Aided Analysis and Design of Facility Layout
Using Ant Colony Optimization
--Manash Bhuyan
Locating healthcare services and designing its layout in a community is not an everyday decision for decision makers. The facility must be located and designed to meet both current and future demand and it must be optimized. Designing the facility layout is generally a Quadratic Assignment Problem (QAP). In this paper, it has been proposed to carry out a study of evolutionary models such as Ant Colony Optimization (ACO) for selecting optimal layout design for a healthcare unit. A survey is conducted in Goalpara district, Assam, India. In this paper, only ants or patients are considered who give only one visit to a particular department in the healthcare unit. That is why the number of interdepartmental movements of ant is taken as 1. The proposed layout is finally compared with the existing layout of the healthcare unit and checked for the effectiveness of the proposed layout. The techniques applied under the present investigation will definitely help the decision manager to select the best optimized facility layout for healthcare unit.

Image, Audio and Video Watermarking
Using LSB and DCT
--Gaurav Khare and Vijay Khare
Watermarking is used to verify the identity and authenticity of the owner of a digital image. It is a process in which the information which verifies the owner is embedded into the digital image or signal. These signals could be either videos or pictures or audios. There are two types of watermarking: visible watermarking and invisible watermarking. The two watermarking algorithms are explained with procedure of image, audio and video watermarking. The first algorithm is based on the Discrete Cosine Transform (DCT) (in the frequency domain) and the second algorithm is based on the Least Significant Bit (LSB) replacement (in the spatial domain). The results are compared under different kinds of attacks.

An Analysis of Requirements Prioritization
in Large, Medium and Small Software Organizations
--Sita Devulapalli, O R S Rao and Akhil Khare
Software products and solutions being developed at large, medium and small software organizations go through similar processes. Yet, due to the nature of the software developed, there are variations in the relevant parameters’ influence on requirements prioritization. The paper analyzes the requirements prioritization across 61 organizations with 106 participants. The study focuses on analyzing the common aspects and variations across large, medium and small organizations. The parameters used in practice and the order they used are identified across the organizations.
