One of the major practices of cloud computing is the storage service that it offers. In spite of its many creditable advantages, it also has some disadvantages like data security and data availability. These two are the main issues that a user face. Many models have been proposed to solve these issues. These models use cryptographic methods to secure the data and data redundancy method to ensure data availability. Both these methods solved the issues at the cost of extra storage space and increased time consumption both at the user and at the server side. This paper recommends a model PCSP (Protected Cloud Service Provider) which solves these issues in a novel way. The model uses light weight techniques which does not employ cryptographic methods. PCSP uses a layered approach, with three entities – the user, the PCSP, and the vendor. Due to the use of light weight techniques, the execution time is reduced by 80% and the storage needed is also reduced by 60%. Thus, there is still more reduction in the storage space. The implementation and analysis serve as the proof of concept [ABSTRACT FROM AUTHOR]

Test data generation is challenging in software testing. Huge amount of generated test data is used to expose faults in the software. Test data generated inefficiently leads extra efforts. In path testing different independent paths generated from Control Flow Graph (CFG) are forced to traverse by test data. In the present paper, we proposed a novel technique to dynamically reduce test data based on Equivalence partitioning of output domain. Paths which are functionally meaningful are considered for test data generation. Experiments are performed on benchmark programs. [ABSTRACT FROM AUTHOR]

Component-Based Software Development (CBSD) process is broadly being adopted by the academicians and industry for the development of software. The industry largely accepted Unified Modeling Language (UML) as the standard for developing for software modeling notations and diagrams. Traditionally, software development methodologies were used with conventional approaches that followed, for example, waterfall process model, etc. After that moved towards object-oriented abstractions, which were finally supported by object-oriented methodologies. The software development process system has three different views-structural view, behavioral view and interactional view. This paper proposes a UML class model for developing a component-based software. Activity diagram and sequence diagram are also designed for the component-based software. [ABSTRACT FROM AUTHOR]

India is a vast country which is rich in culture and diversity. We can see great variations in culture and religion within a state. Nearly two-thirds of the Indian population lives in rural areas. This group of population is largely poor and needs support for development in various areas such as education, agriculture and craft. The need of the hour is to work towards the growth and development of the country in the field of education. This paper proposes a model using Unified Modeling Language (UML) class diagram, activity diagram and sequence diagram for the Indian Educational System (IES). The author also discusses the challenges and gives suggestions for providing quality education to the rural community. [ABSTRACT FROM AUTHOR]

The present paper deals with an effective approach to modeling--UML modeling for the design of an aircraft system. Aircraft contains a large number of generic components, which need to be modeled for effective and efficient functioning of the aircraft system. The class and object diagrams are designed for all generic components of the aircraft system and the sequence diagram is also given for the functioning of the aircraft system. On the basis of the presented model, performance estimation is also done for the efficient working of the aircraft system model. [ABSTRACT FROM AUTHOR]
