the first and second laws of thermodynamics have been employed to evaluate energy and exergetic efficiency of the single effect absorption chiller which is used for air conditioning purpose. the performance analysis has been carried out by developing a computer program in ees and modeling the chiller and its components. to evaluate entropy of the water/lithium bromide solution at any point, an ...

This paper proposes an evolutionary approach to solve the problem of assigning cells to switches in the planning phase of mobile cellular networks. Well-known in the literature as an NP-hard combinatorial optimization problem, this problem requires the recourse to heuristic methods, which can practically lead to good feasible solutions, not necessarily optimal, the objective being rather to red...

Recently proposed multiple input multiple output radars based on matrix completion (MIMO-MC) employ sparse sampling to reduce the amount of data that need to be forwarded to the radar fusion center, and as such enable savings in communication power and bandwidth. This paper proposes designs that optimize the sharing of spectrum between a MIMO-MC radar and a communication system, so that the lat...

To face the challenges of industrial revolution 4.0 and society 5.0, Indonesian nation must continue to prepare quality future generations through education. Educational institutions are required realize human resources who have creative thinking, critical thinking problem solving, communicating, collaborating called 4C. This study aims get an overview implementation interactive conceptual inst...

The road side infrastructure plays a vital role for any Vehicular Ad-hoc Network for implementing a rich set of applications like traffic monitoring and management, road disaster mitigation etc. This is the reason that efficient communication between the vehicles and the road side infrastructure is required. The application under consideration is providing a zero traffic lane (Z-Lane) for an am...

– As parallel library standards make it easier to use networks of workstations for large computational jobs, concentration must be placed on the underlying communication mechanism used by the library. Also, with dynamic resource allocation schemes and task migration, it is now possible to move tasks in mid–execution to exploit architectures that offer faster communication networks. This paper d...

In modern world of communication systems, various new methods have developed to replace the previous conventional techniques that provide data communication with high speed. As wireless communication guidelines were developed it became necessary to develop new techniques like Orthogonal Frequency Division Multiplexing (OFDM) for data security and reliability while data transmission. Idea behind...

Decentralized Partially Observable Markov Decision Processes (Dec-POMDPs) provide powerful modeling tools for multiagent decision-making in the face of uncertainty, but solving these models comes at a very high computational cost. Two avenues for side-stepping the computational burden can be identified: structured interactions between agents and intra-agent communication. In this paper, we focu...

We deal with compiler support for parallelizing perfectly nested loops for coarse-grain distributed memory machines. The relatively high communication start-up costs in these machines renders frequent communication very expensive. We study the eeect of clustering communication and the ensuing loss of parallelism on performance and propose a method for aggregating a number of loop iterations int...
