Under a WHO collaborative study, the Chandigarh center monitored two geographically defined populations over a 2-year period. Using helping-agency-coverage and other methods along with a set of specified criteria, 268 first-onset potentially schizophrenic cases were actively identified. Of these, 232 cases could be assessed in detail which included 209(More)
BACKGROUND AND THE PURPOSE OF THE STUDY Itraconazole is a poorly water soluble drug which results in its insufficient bioavailability. The purpose of the present study was to formulate Itraconazole in a nanosuspension to increase the aqueous solubility and to improve its formulation related parameters, dissolution and hence oral bioavailability. METHODS(More)
With the growth of IT and software industry there has been a shift in the software development paradigm from traditional techniques based to object-oriented and component-based development techniques. Due to this shift dynamic changes occur in the technology, environment and many other qualitative/quantitative factors, leading to increased maintenance(More)
Although a number of nature inspired algorithms exist in literature to solve optimization problems, yet there is always a need of new algorithm which can search for optimum solution in minimum time. This paper proposes a new optimization algorithm for solving optimization problems. Proposed algorithm has been compared with existing algorithm like Genetic(More)
PGP (Pretty Good Privacy) is most widely used standard in the world for securing electronic mails. It promises for confidentiality, integrity and authentication to its users. These security services are provided at a cost of various cryptographic algorithms. Given a data, choosing particular algorithms for its security, according to the user requirements,(More)
Regression testing is an expensive and frequently executed maintenance process used to revalidate modified software. Various problems are associated with regression testing such as regression test selection problem, coverage identification problem, test case execution problem, test case maintenance problem etc. In test selection problem, appropriate and(More)
Natural phenomenon can be used to solve complex optimization problems with its excellent facts, functions, and phenomenon. In this paper, a survey on physics-based algorithm is done to show how these inspirations led to the solution of well-known optimization problem. The survey is focused on inspirations that are originated from physics, their formulation(More)
Software estimation accuracy is one of the most difficult tasks for software developers. Defining the project estimated cost, duration and maintenance effort early in the development life cycle is greatest challenge to be achieved for software projects. Formal effort estimation models, like Constructive Cost Model (COCOMO) are limited by their inability to(More)
Many real life problems require optimization of more than one objective functions, these problems are known as multi-objective optimization problems. Although many algorithms are available in literature to solve these types of problems [2, 3, 4, 5, 21] but they treat every objective function equally. Sometimes, on the basis of problem to be optimized,(More)
Establishing trust in a distributed computing environment is one of the most challenging and important aspects of cluster computing. Achieving optimal performance in clusters forces the migration of processes to other nodes. This is where trust comes into play. A secure trusted environment is needed in order to ascertain the credibility of the participating(More)
