In this paper, the charge and discharge strategies were conducted for a future battery energy storage system (BESS) at the National Penghu University of Science and Technology. OpenDSS software was used to establish the power distribution system. A probabilistic neural network model was used to predict the daily load and photovoltaic (PV) generation curve for controlling the charge-discharge of the...
Electricity markets in countries around the world are being restructured in pursuit of economic efficiency through competition. However, unpredictability in electricity prices and previous occurrences of market failure have indicated a need to better understand the complex interactions between the various market participants as well as to design market rules that maximizes efficiency and security...
With the focus on India-Israel Defense relations three modeling aspects - Multiple Regression on EV/EBTIDA multiple, Projections of share price by Monte Carlo Simulation and Rank Correlation (current year) are being utilized for the study. The result suggested that the contribution in multiple (based on MLR) is more from debt and intercept in the companies of Israel and USA. Indian companies are not...
This paper presents the results of a comprehensive literature survey and a web based survey on the use of Scrum in offshore software development (OSD) in Sri Lankan context. The trend in the recent software development industry is to move towards OSD. Issues and challenges related to OSD have to be solved to gain success. Scrum has gained a significant attention due to its flexible approach to managing...
Joint use rental rates on utility poles are generally determined by the amount of space utilized by each of the parties attached to the pole. However, another very important aspect of joint use on poles is structural strength. With more and larger communication cables, this issue has become more of a concern. Could rental rates be based on structural strength? What happens if a past attacher has caused...
Context-aware e-Services offer entirely new opportunities for application developers and for end users by gathering context data and offering e-services solutions that are adapted to their context. In this paper, using a scenario, we argue for the need for an e-services framework that supports decision-making during fault management process in electricity distribution networks. Then we discuss the...
SMEs are major contributors to the Malaysia's economic growth. They constitute about 99.2% of registered companies in Malaysia. E-business is believed could help to increase the SMEs competitiveness by venturing into global and virtual marketplace. However, it is reported that only 20% of SMEs have an Internet presence but not fully e-business. Among the limitations that the SMEs faced are lack of...
As world populations increase, the demand for non-renewable resources forces organizations to pursue mega projects in sparsely or non populated regions. Worldwide trends towards urbanization make it increasingly difficult to attract and hold skilled workers in these less attractive locations. As well, the skill sets required to design and build the large projects may not be required within the organization...
Measures need to be in place during the construction phase to insure that the final project design adheres to the contract specifications and that the project progress is in line with the contract document and that the resources are managed accordingly. This is where information technology would benefit the project management aspect of construction and provide information integration throughout all...
Enhance the efficiency of energy usage and lower energy costs have gained attention in the recent years. Prior research has neglected the transaction structure of energy management service. This study investigated the ex ante and ex post transaction costs with respect the contracting between Energy Service Company (ESCOs) and energy demanders. Combined with the internal control mechanisms and the...
Poor project governance is the main cause of project failures for complex projects. Historically, formal contracting has been the mainstay of project governance for outsourced projects. However, subsequent studies found that reliance on formal contracting typically results in adversarial relationship between clients and contractors in large construction projects, which exacerbates chances of project...
Gathering time spent data on IT Maintenance work can burden your officers with a significant amount of manual records keeping for time they spent on individual calls and other activities. This paper describes how we eased the burden on the officers, but still were able to gather detailed data regarding their time spent for most of the activities performed by them, and thus were able to collect valuable...
Regionalization of software and hardware engineering in international project business is a key driver for the success of multinational companies. These companies usually act as prime contractors and therefore have to execute large engineering projects across several countries. This requires a shift of the whole or at least a portion of their engineering value chain to a foreign country (regionalization)...

An Optimistic fair exchange (OFE) protocol is a protocol for fairly exchanging items between two parties. First in 2008, Huang et al. introduced the concept of ambiguous OFE in which the partial signature is ambiguous but the full one is not. Qu et al. in 2012, proposed a shceme with ambiguity for the full signature but not for the partial one. We solve the problem of both schemes by proposing the...
Negotiation is a fundamental mechanism in multi-agent systems since it allows self-interested agents to come to mutual agreements and to distribute resources efficiently and effectively. However, in competitive situations, the agents need to negotiate repeatedly with one another, thus developing mechanisms that are effective over repeated interactions is a key challenge. At present, few research work...
