Thirty-eight assignments and forty-four final reports submitted by the different business management students enrolled in different semesters were analysed to describe the causes, effects and solutions for the academic writing deficiencies of business management students. It also analysed the different most frequently occurred grammatical errors. Based on the findings, the study recommended a 5-step criterion to measure the adequacy of academic writing of business students. Based on its general applicability to the business students, the criterion is acceptable by any business school offers academic courses in English as a second language. Different demographic variables should be used for the use of this criterion in practice to explore the differences found based on gender, race, ethnicity, background etc. However, the most important use of this 5-step criterion is to evaluate the academic writing deficiencies experienced by a particular group of business students. Therefore, the scope of this study is applicable, but not limited to the business schools professors, business school students, and business schools course designers/developers.

Many routing protocols have been proposed and tested under various traffic loads and speeds for MANETs. However, the simulations of such routing protocols usually do not consider the nomadic velocities of MANET participants witnessed in real-world scenarios, which may have significant impact on the performance of MANET routing protocols. In this paper, we have designed four scenario-based mobility models having various speeds of MANET participants to compare the performance of DSDV and AODV routing protocols. The simulation results indicate that DSDV protocol is suitable for HRM and HWM models under high traffic load.

Most of the time black hole attack occurs in large Ad Hoc networks. The black hole attacks in wireless Ad Hoc network creates misunderstanding in network by introducing error in routing information that

The key to mediator approach is storing and retrieving XML documents in a relational database, providing a user interface for XML manipulation, independent of proprietorship and without doing any modification in its basic structure. After the implementation of the mediator, the RDBMS becomes repository for both XML and relational data simultaneously. The mediator has flexibility to add any proposed more efficient schema-oblivious XML mapping strategy as a new collection. The mediator can also be used as the benchmarking tool for the researchers to compare various schema-oblivious XML mapping strategies after adding them as a new collection. The comparative studies of insertion, retrieval and query performance of these two types of mapping strategies are produced as well

Explicitly parallel programs are multi-dimensionalobjects; the natural representations of a parallel program are annotated directed graphs:data flow graphs, control flow graphs, etc. where the nodes of the graphs are sequentialcomputations. A visually based (directed graph) representation of parallel programs is thusmore natural than a pure text string

The system is first trained by cloud images. In training phase, system reads major principal features of the different cloud images to produce an image space. In testing phase, a new cloud image can be classified by comparing it with the specified image space using the ...

UCD-Generator is an automated system that has vigorous ability to directly interact wit the user. This research paper presents a natural language processing based approach LESSA that is used for automatically understanding the natural language text and extract required information. This information is used to draw the use case diagrams. User writes his interface based preferences in simple English in a few paragraphs and the designed system has conspicuous ability to analyze the given script. After compound analysis and extraction of associated information, the designed system actually draws the use case class diagrams. Other conventional CASE tools require a complete understanding of the intended business scenario and lot of extra time and efforts from the system analyst during the process of creating, arranging, labeling and finishing the USE case diagrams. The designed system provides a quick and reliable way to generate use case diagrams to save the time and budget of both the user and system analyst.

Reusability of software components stands for using the existing design and developed components in new software applications to save the cost and time. Against these persuading facts, some vexing problems also subsist there as to reuse which components and how to search those particular components from the given designed scenario. The newly designed rule based framework is fairly efficient in ...

For such purpose different patterns and data models are used, but most of them deal in few specific situations. Thesis of this research is to identify such pattern that covers most of the business transactions. Hence transaction pattern is
