financial statement of a company is a reflection of the operational and financial position of a company. the comparative analysis of two companies similar in nature, size, work, location and objectives etc., facilitates an understanding of the operational and financial soundness of the companies. the kingdom of saudi arabia is aiming for rapid industrialization in its economy. sahara petrochemi...

I n a recent report that summarizes the reasons that hospitals undertake construction projects, “operational efficiency and patient flow” are cited as the most common objectives (Carpenter 2004). Intuitively, improvements in operating efficiency should flow from more modern and efficient building systems, streamlined clinical and business processes, more appropriate departmental adjacencies, an...

The recent consumer-to-consumer (C2C) Internet auction boom at eBay, Yahoo, Amazon, and other sites has added new theoretical challenges to the science of auctions. This paper uses experiments with economically-motivated human subjects to measure the operational efficiency of decentralized Internet auction mechanisms as they compare to centralized double auction mechanisms. Subjects are recruit...

Improving the efficiency of public transport systems is a critical problem. In order to help implement strategies for improving efficiency, public transport managers and researchers need access to an upto-date information system that fully describes these strategies including data on their quantitative benefits. This research outlines a proposal for developing such a database and how it might b...

1.Introduction Energy efficiency and environmental performance are mainstream issues for ship operators who are aiming through low carbon shipping and cost reductions. Although reducing fuel consumption seems to have priority, environmental considerations also push the shipping industry to operate in more efficient way. Strict legislations on GHG emissions and increasing fuel prices turn the fo...

An abstract argumentation framework and the semantics, often called Dungean semantics, give a general framework for nonmonotonic logics. In the last fifteen years, a great number of papers in computational argumentation adopt Dungean semantics as a fundamental principle for evaluating various kinds of defeasible consequences. Recently, many papers address problems not only with theoretical reas...

Empirical evidence suggests that in practice it is difficult to reach Pareto optimal agreements in negotiations. In this paper, we take a constructive approach to this question in two-party negotiations over continuous issues. A new negotiation procedure is presented that results in Pareto optimal agreements under fairly general assumptions. The procedure uses a mediator who assists the decisio...

The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent on various parameters such as impeller shape, size and speed of impeller, baffle size, residence...
