A classical NP-hard problem is the Minimum Edge Clique Cover (minECC) problem, which is concerned with covering the edges of a network (graph) with the minimum number of cliques. There are many real-life applications of this problem, such as in food science, computational biology, efficient representation of pairwise information, and so on. Borrowi...

Triangles are an essential part of network analysis, representing metrics such as transitivity and clustering coefficient. Using the correspondence between sparse adjacency matrices and graphs, linear algebraic methods have been developed for triangle counting and enumeration, where the main computational kernel is sparse matrix-matrix multiplicati...

The Edge Clique Cover (ECC) problem is concerned with covering edges of a graph with the minimum number of cliques, which is an NP-hard problem. This problem has many real-life applications, such as, in computational biology, food science, efficient representation of pairwise information, and so on. In this work we propose using a compact represent...

A prime concern of a Shortest-Path problem is to handle any real edge weight values whether it is positive or negative with the feature of negative weight cycle detection if exists. Number of single source shortest-path algorithms are available that can handle negative weight cycle, where the most stable algorithm till date executes with polynomial...

Traffic congestion is a common scenario in the metropolitan areas specially in developing countries like Bangladesh where people lose valuable time of their busy schedule by getting trapped in heavy traffic. Moreover, reliable traffic congestion avoidance or prediction mechanism for providing real-time traffic jam information and route selection is...

Bangladesh is one of the most densely populated countries in the world, where a significant number of populations are suffering eye health and visionary problems. Over the last decade, a rapid growth of ICT uses has shown in Bangladesh. Thus ICT based health services would be an effective solution for providing the better health services to the cit...

People spend a lot of time at their workplace, for example in office environment. After consuming breakfast or lunch during the recess periods, one may feel lazy both physically and mentally. Thus, gaining extra calories may lower the working progress. To motivate individuals for healthier behavior, we designed, executed and tested an application f...

In comparative genomics, a common issue is to find the shortest course of operations for the transformation of one genome into another. During rejoining the blocks, inverted block interchange, a more distinct form of block interchange, gives the option to the blocks to reverse their orientation. In this particular paper, we have presented an improv...

Floorplanning is an important problem in very large scale integrated-circuit (VLSI) design automation as it determines the performance, size, yield, and reliability of VLSI chips. It is an important step of VLSI design methodology. It gives answer to the different question of VLSI design such as shape of modules, location of modules etc. The floorp...

A classic problem in comparative genomics is to find a shortest sequence of evolutionary operations that transform one genome into another. There are different types of genome rearrangement operators such as reversals, transpositions, translocations, block interchange, double cut and join (DCJ) etc. In this paper we consider reversals and block-int...

Stirling engine is an external combustion engine that can successively replace conventional fuel by means of alternative fuel (low grade fuel or renewable energy such solar thermal energy) for power generation. The proposed system improves the total output by maximum utilization of available photovoltaic output and maximum utilization of the durati...

This research paper carries out a realistic experimental approach to enhance the solar output power to a significant level with the application of solar concentrator and tracking system and also proposes a fuzzy based control system for the utilization of the duration for which solar power is available. By using only a solar panel, the theoretical...

A novel concept for fuzzy based switching controlled solar energy powered irrigation system is proposed. Superior to existing systems, increasing the water output for same PV capacity, while reducing capital cost for same water output. The proposed system improves the total output of water by maximum utilization of available photovoltaic output and...
