This paper establishes five new facts about instructional costs in higher education using department-level data from a broad range of institutions. Costs vary widely across fields, ranging ele...

This paper focuses on the importance of decoupling recurrent supply risk and disruption risk when planning appropriate mitigation strategies. We show that bundling the two uncertainties leads a manager to underutilize a reliable source while over utilizing a cheaper but less reliable supplier. As in Dada, Petruzzi and Schwarz [6], we show that increasing quantity from a cheaper but less reliabl...

Crowdsourcing provides a popular paradigm for data collection at scale. We study the problem of selecting subsets of workers from a given worker pool to maximize the accuracy under a budget constraint. One natural question is whether we should hire as many workers as the budget allows, or restrict on a small number of topquality workers. By theoretically analyzing the error rate of a typical se...

We study the problem of Non-Rigid Registration (NRR) for intra-operative recovery of brain shift during image-guided neurosurgery. Time-critical nature of the tumour resection procedure presents a major obstacle to the routine clinical use of many available NRR approaches. In this paper, we utilise the resources of a single multicore workstation with an advanced graphics card to parallelise and...

Vertical kilometer foot races consist of a 1,000-m elevation gain in <5,000 m of overall distance, and the inclines of the fastest courses are ∼30°. Previous uphill locomotion studies have focused on much shallower angles. We aimed to quantify the metabolic costs of walking and running on very steep angles and to biomechanically distinguish walking from running. Fifteen runners (10 male, 5 fema...

A tightly focused beam of light can attract and trap micron-sized dielectric particles whose refractive index exceeds that of the surrounding medium. Although single-beam optical traps were developed only in 1986, they have already proven their worth in making possible an increasing number of experiments. Optical traps have found particular use in biophysics, where they allow one to manipulate ...

In designing software applications, the enduring process faces realistic business challenges to overcome the restricted time, limited resources, and quality constraint in engineering paradigm. Overemphasizing the three engineering limitations upsets the balance of producing highest quality, shortest time, and lowest budget cost during product development lifecycle at the highest efficient mode....

The use of reverse auctions for procurement activities has grown tremendously over the last several years. The majority of these auctions use a single dimension (price) format while providing constraints on non-price attributes such as quality and lead time. In this research, we present an auction mechanism for a buyer whose utility function is known and dependent on three attributes: price, qu...

Determining management’s information needs is historically one of the most time consuming and errorprone activities in designing and building information systems. Most managers spend half their time obtaining needed information, either informally through meetings, phone conversations, or reading; or formally through organizational computer-based information systems. During this process they hav...

This paper discusses results from the MATTER project (MATerials Technologies for greenhouse gas Emission Reduction). The goal of the project is to provide more insight into the potentials to reduce greenhouse gas (GHG) emissions in Western Europe through changes in the production of materials and the use of materials. GHG emission reduction is one of the key environmental problems for the susta...
