Authentication and authorization are two tightly coupled and interrelated
concepts which are used to keep transactions secure and help in protecting
confidential information. This paper proposes to evaluate the current
techniques used for authentication and authorization also compares them with
the best practices and universally accepted authentication and authorization
methods. Authentication verifies user identity and provides reusable
credentials while authorization services stores information about user access
levels.

The software industry is successful, if it can draw the complete attention of
the customers towards it. This is achievable if the organization can produce a
high quality product. To identify a product to be of high quality, it should be
free of defects, should be capable of producing expected results. It should be
delivered in an estimated cost, time and be maintainable with minimum effort.
Defect Prevention is the most critical but often neglected component of the
software quality assurance in any project.

This paper addresses the path selection problem from a known sender to the
receiver. The proposed work shows path selection using genetic algorithm(GA)and
simulated annealing (SA) approaches. In genetic algorithm approach, the multi
point crossover and mutation helps in determining the optimal path and also
alternate path if required. The input to both the algorithms is a learnt module
which is a part of the cognitive router that takes care of four QoS
parameters.The aim of the approach is to maximize the bandwidth along the
forward channels and minimize the route length.

The increase in dissipated power per unit area of electronic components sets
higher demands on the performance of the heat sink. Also if we continue at our
current rate of miniaturisation, laptops and other electronic devices can get
heated up tremendously. Hence we require a better heat dissipating system to
overcome the excess heat generating problem of using nanoelectronics, which is
expected to power the next generation of computers.

The main goal of this research is to develop the concepts of a revolutionary
processor system called Functional Processor System. The fairly novel work
carried out in this proposal concentrates on decoding of function pipelines and
distributing it in FPUs as a part of scheduling approach. As the functional
programs are super-level programs that entails requirements only at functional
level, decoding of functions and distribution of functions in the heterogeneous
functional processor units are a challenge.

Defect Prevention is the most critical but most neglected component of the
software quality assurance in any project. If applied at all stages of software
development, it can reduce the time, cost and resources required to engineer a
high quality product. Software inspection has proved to be the most effective
and efficient technique enabling defect detection and prevention. Inspections
carried at all phases of software life cycle have proved to be most beneficial
and value added to the attributes of the software.

Segmentation of medical images using seeded region growing technique is
increasingly becoming a popular method because of its ability to involve
high-level knowledge of anatomical structures in seed selection process. Region
based segmentation of medical images are widely used in varied clinical
applications like visualization, bone detection, tumor detection and
unsupervised image retrieval in clinical databases. As medical images are
mostly fuzzy in nature, segmenting regions based intensity is the most
challenging task.

This paper reviews application of Artificial Neural Networks in Aircraft
Maintenance, Repair and Overhaul (MRO). MRO solutions are designed to
facilitate the authoring and delivery of maintenance and repair information to
the line maintenance technicians who need to improve aircraft repair turn
around time, optimize the efficiency and consistency of fleet maintenance and
ensure regulatory compliance. The technical complexity of aircraft systems,
especially in avionics, has increased to the point at which it poses a
significant troubleshotting and repair challenge for MRO personnel.
