  Problem statement: Several efficient algorithms were developed to cope with the popular task of sorting. Improved heap sort is a new variant of heap sort. Basic idea of new algorithm is similar to classical Heap sort algorithm but it builds heap in another way. The improved heap sort algorithm requires nlogn-0.788928n comparisons for worst case and nlogn-n comparisons in average case. This algorithm uses only one comparison at each node. Hardware has impact on performance of an algorithm. Since improved heap sort is a new algorithm, its performance on different hardware is required to be measured. Approach: In this comparative study the mathematical results of improved heap sort were verified experimentally on different hardware. To have some experimental data to sustain this comparison five representative hardware were chosen and code was executed and execution time was noted to verify and analyze the performance. Results: Hardware impact was shown on the performance of improved heap sort algorithm. Performance of algorithm varied for different datasets also. Conclusion: The Improved Heap sort algorithm performance was found better as compared to traditional heap sort on different hardware, but on certain hardware it was found best.

  A major problem in designing a large-scale parallel and distributed system was the construction of an Interconnection Network (IN) to provide inter-processor communication. One of the biggest issues in the development of such a system was the development of an effective architecture and algorithms that have high reliability, give good performance (even in the presence of faults), low cost, low average path length, higher number of passes of request and a simple control. In this study, a new class of Irregular Fault Tolerant Multistage Interconnection Network (MIN) called Improved Four Tree (IFT) is introduced. Algorithms for computing the cost and permutations passable in the presence and absence of fault are developed for the analysis of various networks with proposed network.

  These days, majority of electronic devices work on DC power source, so there was a requirement of a reliable and customized power supply. Generally, the requirements are not too varied, but still they require every time a new hardware designing. The idea presented here is to build a microcontroller controlled power supply[1] that is flexible enough to meet different customer requirements, with minor software changes and no corresponding hardware change. Hardware issues are discussed, with a goal of developing a generalized power supply that has programmable output voltage and current. It is able to recognize faults and take corrective actions to prevent any permanent damage to the system. The system discussed here is capable of functioning independently by its own without any intervention from the user. The system finds application at remote sites to automatically manage primary (AC) and secondary (Battery) power sources to provide smooth uninterrupted power output even during switchovers between AC and DC power sources. It would also be helpful to insurance companies who expect that the products covered by them be reliable, robust and not prone to be damages.
