In this paper the performance evaluation has been done for combinatorial code for different system and code parameters under noisy optical channel conditions for potentially increasing number of users for optical code division multiple access system. It has been observed that code weight and effective power from each user are two main factors to decide the system performance. KeywordsOptical Co...

Credit scoring has been regarded as a core appraisal tool of different institutions during the last few decades, and has been widely investigated in different areas, such as finance and accounting. Different scoring techniques are being used in areas of classification and prediction, where statistical techniques have conventionally been used. Both sophisticated and traditional techniques, as we...

PERFORMANCE EVALUATION FOR COMMUNICATION SYSTEMS WITH RECEIVE DIVERSITY AND INTERFERENCE

Performance, performance and performance used to be the three things that really mattered in database research. Most of our published works indeed include an experimental evaluation of the proposed techniques. However, such evaluations are sometimes seen as a ”must-have” eating up the valuable space where one could describe new ideas. The experimental evaluations end up being short, lacking imp...

StarBED is a network testbed begun in 2002 focused on running actual program code for software and hardware implementations. As hardware technologies develops, its facilities such as PCs and network equipments have been updated and we additionally developed SpringOS, a software support suite consisting of numerous program modules. The performance of StarBED and SpringOS increases as their equip...

Academic writing, whether individual or cooperative, is an essential skill for today's graduates. However, motivating and helping students to learn to write effectively, either in cooperative or individual scenarios, poses many challenges, many of which can be overcome by technical means. The aim of this study is to investigate the effect of using cooperative and individual weblogs to enhance w...

We identify the tunable parameters of iSCSI and TCP that affect the performance characteristics for local, metropolitan, and wide area networks. Through measurements, we determine the effect of these parameters on the throughput. We conclude that with the appropriate tuning of those parameters, iSCSI and TCP protocols maintain a good level of throughput for all types of networks.

The goal of this study is to evaluate the accuracy of the Portuguese thermal regulation simplified methodology for existing buildings and to assess the influence of different parameters on the building final energy performance evaluation. Simple “in-situ” measurement techniques were carried out to calibrate the input data in this methodology. The results obtained with the simplified methodology...
