The Danish Ministry of Culture has funded a project to set up a model for costing preservation of digital materials held by national cultural heritage institutions. The overall objective of the project was to increase cost effectiveness of digital preservation activities and to provide a basis for comparing and estimating future cost requirements for digital preservation. In this study we descr...

We present a quantitative approach for IT portfolio management. This is an approach that CMM level 1 organizations can use to obtain a corporate wide impression of the state of their total IT portfolio, how IT costs spent today project into the budgets of tomorrow, how to assess important risks residing in an IT portfolio, and to explore what-if scenarios for future IT investments. Our quantita...

A considerable amount of work has recently been applied to the development of processes to reduce negative environmental impacts of disposal products. Different waste reduction options such as direct reuse, repair, refurbishing, cannibalization, and remanufacturing were introduced to overcome these shortages. This paper studies an integrated system of manufacturing and remanufacturing using a c...

    Background: Hip, vertebral and wrist fractures are the most common consequences of osteoporosis. This study aimed at analyzing the cost-effectiveness of teriparatide (CinnoPar®), compared with alendronate and risedronate, in the treatment of women aged 60 and over with postmenopausal osteoporosis in Iran.    Methods: A decision tree model with a 2-year time hor...

The Peer-to-Peer (P2P) paradigm dictates a distributed network model which enables the sharing of resources between its participants. In many cases, the location of these resources is a non-trivial task with network-wide effects. In this work, we describe the Adaptive Probabilistic Search method (APS) for search in unstructured P2P networks. APS utilizes feedback from previous searches to proba...

Explaining the maintenance of sexual reproduction remains one of the greatest challenges in biology. The theoretical oddity of sex is based on at least three advantages that asexual organisms have over sexual ones: 1Asexuals, by not producing males, have a two fold advantage over sexuals, regarding the number of reproductive individuals; 2Sexuals have an evolutionary disadvantage over asexuals,...

Due to globalization and the growth of international trade, many container terminals are trying to improve performance in order to keep up with demand. One technology that has been proposed is the use of Automated Guided Vehicles (AGVs) in the handling of containers within terminals. Recently, a new generation of AGVs has been developed which makes use of cassettes that can be detached from the...

Some leading e-Commerce sites (B2C) provide customers with over-personalized spaces which do not seem to be necessary. Why do the site providers provide such unnecessary capabilities for customers? Is it an effective marketing strategy? This study proposes the concept of “psychological ownership” for examining the impact of e-Commerce sites’ personalized spaces on customer perception and behavi...

in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...

the purpose of this article is to investigate a two-echelon supply chain inventory problem consisting of a single-vendor and a single-buyer with controllable lead time and investment for quality improvements. this paper presents an integrated vendor-buyer inventory model in order to minimize the sum of the ordering cost, holding cost, setup cost, investment for quality improvement and crashing ...
