There is an increasing need for the ship design process to take account of environmental issues such as the emission of greenhouse gases and the likely extension of a carbon dioxide charging mechanism to international shipping. These issues, together with the need for economic viability, provide further incentives to improve the efficiency of propulsion of ships. The main components of powering...

The thesis focuses on evaluating and improving the transport efficiency of two types of logistics operations in the supply chain. One research area is the production of raw material in heavy construction operations, which takes place early in the construction supply chain. The production of raw material, specifically earthmoving operations, involves the moving and processing of the soil surface...

We employ ratio-based, deterministic, and stochastic frontier approaches to investigate fuel efficiency among 15 large jet operators (mainline airlines) in the U.S. Given the hub-andspoke routing structure and the consequent affiliation between mainline and regional carriers, we consider not only fuel efficiency of individual mainline airlines, but also the joint efficiency of each mainline and...

Selecting a minimal-cost team from a set of agents, with associated costs, to complete a given set of tasks is a common and important multiagent systems problem. Some degree of fault-tolerance in such teams is often required which enables the team to continue to complete all tasks even if a subset of the agents are incapacitated. A k-robust team is one that is capable of completing all assigned...

A comparison of 10 most popular Multiple Sequence Alignment (MSA) tools, namely, MUSCLE, MAFFT(L-INS-i), MAFFT (FFT-NS-2), T-Coffee, ProbCons, SATe, Clustal Omega, Kalign, Multalin, and Dialign-TX is presented. We also focused on the significance of some implementations embedded in algorithm of each tool. Based on 10 simulated trees of different number of taxa generated by R, 400 known alignmen...

PURPOSE Genomic technologies make it increasingly possible to identify patients most likely to benefit from a molecularly targeted drug. This creates the opportunity to conduct targeted clinical trials with eligibility restricted to patients predicted to be responsive to the drug. EXPERIMENTAL DESIGN We evaluated the relative efficiency of a targeted clinical trial design to an untargeted des...

Text mining refers to the process of deriving high quality information from text. It is also known as knowledge discovery from text (KDT), deals with the machine supported analysis of text. It is used in various areas such as information retrieval, marketing, information extraction, natural language processing, document similarity, and so on. Document Similarity is one of the important techniqu...

radial models of dea to measure the efficiency of dmus assumed an inefficient unit to be efficient must decrease (increase) proportional all inputs (outputs) as the same. this assumption is absolutely false, unnecessary and unrealistic, therefore, to address this deficiency, and raise awareness of how to use resources, it is so realistic that expect the various inputs have different efficiency....
