A digital repository can be seen as a combination of services, resources, and policies. One of the fundamental design questions for digital repositories is how to break down the services and resources: who will have responsibility, where they will reside, and how they will interact. There is no single, optimal answer to this question. The most appropriate arrangement depends on many factors tha...

in this study, under the constraint of resource-saving and environment-friendliness objective, based on multi-agent genetic algorithm, multi-objective spatial optimization (moso) model for land use allocation was developed from the view of simulating the biological autonomous adaptability to environment and the competitive-cooperative relationship. the model was applied to solve the practical m...

In the following paper the process of knowledge generation from the Veterans Administration healthcare information system is explored. This inquiry is concerned with predicting length of stay of a subset of the total patient population, specifically those with spinal cord injuries (SCI). Although SCI patients do not present large numbers, they are outliers in the healthcare system due to extend...

The cumulative resource constraints of the resource-constrained project scheduling problem (RCPSP) do not treat the resource demands as geometric rectangles, that is, activities are not necessarily assigned to the same resource units over their processing times. In spite of this fact, most papers on resource-constrained project scheduling mainly in the motivation phase use a strip packing of re...

cultivation of high efficacy crops in resource utilization, especially with higher water and radiation use efficiencies is one of the important strategies to achieve the goals of sustainable agriculture. align with these guidelines and in order to estimate light extinction coefficient and radiation use efficiency of sesame a split plot arrangement of two factors based on randomized complete blo...

It has long been recognized that combined heat and power (CHP) generation can achieve higher end-use efficiencies than conventional systems. By generating electricity at the point of use and utilizing the co-produced heat, CHP generators can achieve net efficiencies in excess of 80%. This nearly doubles the efficiency of our current system, in which large centralized power plants provide electr...

The objective of this study was to determine the economic efficiency of resource utilization in broiler production farms using a nonparametric production function, data envelopment analysis (DEA). Data for the analysis were collected from a cross section of 44 farmers using a multi-stage sampling procedure. In DEA models the farmers that produce their level of output with the least amount of in...

There is no dearth of new robots that provide both generalized and customized platforms for learning and research. Unfortunately as we attempt to adapt existing software components, we are faced with an explosion of device drivers that interface each hardware platform with existing frameworks. We certainly gain the efficiencies of reusing algorithms and tools developed across platforms but only...

Cogeneration of electricity and desalinised water for water production is an accepted principle in many countries. However, there is an opportunity to extend the concept to obtain greater efficiencies by reassessing the desalination paradigm. The new paradigm considers desalination as only part of the saline water processing chain. It looks at value-adding opportunities through further processi...
