Cognitive Process of Comprehension in Requirement Analysis in IT Applications

Requirement Analysis is an important phase in software development which deals with understanding the customers requirements. It includes the collection of information from the customer, which is regarding the customers requirements and what he expects from the software which is to be developed. By doing so, you can have a better understanding of what the customer actually needs and hence can deliver the output as per the customers requirements. Studies are being carried out to bring about improvements in the process of requirement analysis so that errors in software development could be minimized and hence improved and reliable products could be delivered.

GPRS Based Intranet Remote Administration GIRA

In a world of increasing mobility, there is a growing need for people to communicate with each other and have timely access to information regardless of the location of the individuals or the information. With the advent of moblle technology, the way of communication has changed. The gira system is basically a mobile phone technology service. In this paper we discuss about a novel local area network control system called gprs based Intranet Remote Administration gira. This system finds application in a mobile handset. With this system, a network administrator will have an effective remote control over the network. gira system is developed using gprs, gcf Generic Connection Framework of j2me, sockets and rmi technologies

Quantifying the Deign Quality of Object Oriented System The metric based rules and heuristic

The design structure of OO software has decisive impact on its quality. The design must be strongly correlated with quality characteristics like analyzability, changeability, stability and testability, which are important for maintaining the system. But due to the diversity and complexity of the design properties of OO system e.g. Polymorphism, encapsulation, coupling it becomes cumbersome.

Performance Analysis of View Maintenance Techniques for DW

A Data Warehouse stores integrated information as materialized views over data from one or more remote sources. These materialized views must be maintained in response to actual relation updates in the remote sources. The data warehouse view maintenance techniques are classified into four major categories self maintainable recomputation, not self maintainable recomputation, self maintainable incremental maintenance, and not self maintainable incremental maintenance. This paper provides a comprehensive comparison of the techniques in these four categories in terms of the data warehouse space usage and number of rows accessed in order to propagate an update from a remote data source to a target materialized view in the data warehouse.

IT in Power Sector A KPCL Implementation

In this paper we investigate the extent of Information Technology penetration in Power sector, taking KPCL, Karnataka Power Corporation Ltd., a premier power generating, a state owned public sector organization as an example. Any organization to flourish, adoption of Information Technology is inevitable in the days of fast changing technological advancements. It is not merely the investment on IT which helps but adoption of right IT solutions and the optimum use of the same does matter and becomes most critical. A strong infrastructure coupled with modern technical and management concepts has helped KPCL to meet the challenges of the rising energy demands of Karnataka.

Relaxation Control of Packet Arrival Rate in the Neighborhood of the Destination in Concentric Sensor Networks

One of the challenges in the wireless sensor applications which are gaining much attention is the real-time transmission of continuous data packets across the network. Though advances in communication in sensor networks are providing guaranteed quality data packet delivery they still have some drawbacks. One such drawback is transmission of incessant data packets over high speed networks. Here in this paper we have designed a concentric sensor network having buffer just not at the sink but also in selected intermediate nodes to minimize the packet loss caused due to congestion. This approach results in haggle congestion and less packet loss in the designed network.

Software Metrics Evaluation Based on Entropy

Software engineering activities in the Industry has come a long way with various improve- ments brought in various stages of the software development life cycle. The complexity of modern software, the commercial constraints and the expectation for high quality products demand the accurate fault prediction based on OO design metrics in the class level in the early stages of software development. The object oriented class metrics are used as quality predictors in the entire OO software development life cycle even when a highly iterative, incremental model or agile software process is employed. Recent research has shown some of the OO design metrics are useful for predicting fault-proneness of classes. In this paper the empirical validation of a set of metrics proposed by Chidamber and Kemerer is performed to assess their ability in predicting the software quality in terms of fault proneness and degradation. We have also proposed the design complexity of object-oriented software with Weighted Methods per Class metric (WMC-CK metric) expressed in terms of Shannon entropy, and error proneness.

Estimation of Defect proneness Using Design complexity Measurements in Object- Oriented Software

Software engineering is continuously facing the challenges of growing complexity of software packages and increased level of data on defects and drawbacks from software production process. This makes a clarion call for inventions and methods which can enable a more reusable, reliable, easily maintainable and high quality software systems with deeper control on software generation process. Quality and productivity are indeed the two most important parameters for controlling any industrial process. Implementation of a successful control system requires some means of measurement. Software metrics play an important role in the management aspects of the software development process such as better planning, assessment of improvements, resource allocation and reduction of unpredictability. The process involving early detection of potential problems, productivity evaluation and evaluating external quality factors such as reusability, maintainability, defect proneness and complexity are of utmost importance. Here we discuss the application of CK metrics and estimation model to predict the external quality parameters for optimizing the design process and production process for desired levels of quality. Estimation of defect-proneness in object-oriented system at design level is developed using a novel methodology where models of relationship between CK metrics and defect-proneness index is achieved. A multifunctional estimation approach captures the correlation between CK metrics and defect proneness level of software modules.
