A Decision Support System For Real-Time Snow And Ice Control, Hjalmar James Miedema, J. R. Wright Jan 1995

A Decision Support System For Real-Time Snow And Ice Control, Hjalmar James Miedema, J. R. Wright

JTRP Technical Reports

Effective real-time snow and ice control operations require a timely initial call-out. A timely initial call-out is one that mobilizes the workforce slightly prior to the onset of hazardous road conditions. In order to estimate the onset of hazardous road conditions, the snow and ice control decision makers use available physical and meteorological information. New technologies are developed that could provide better information, thereby improving the ability to make timely initial call-outs. A systematic methodology for evaluating the benefit of additional information used in snow and ice control initiation is presented. The purposed methodology compares reduction in the direct and …

Influence Of Blood Flow And Vasoactive Drugs Upon Tissue Temperature Distributions In Local Hyperthermia Therapy, Charles F. Babbs Dec 1994

Influence Of Blood Flow And Vasoactive Drugs Upon Tissue Temperature Distributions In Local Hyperthermia Therapy, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

Effective local hyperthermia for cancer requires selective elevation of intratumoral temperature without overheating of surrounding normal tissues. Temperature elevation depends upon the balance between absorbed power density, which heats the treated tissue, and blood perfusion, which cools it. Selectivity can be achieved by manipulations of vascular physiology to increase blood cooling of normal tissues or to decrease blood cooling of tumor tissue. Creation of a favorable normal-to-tumor blood flow ratio is possible because the small blood vessels supplying most tumors are structurally and functionally different from the microvasculature of normal tissues. Normal arterioles dilate in heated tissues to raise local …

Department of Electrical and Computer Engineering Technical Reports

Each year in the graduate course on "Economic Dispatch and Control of Integrated Power Systems," the students prepare a term project which is assembled into a report. This year, the assigned topic relates to demand side management. This topic appears to be especially timely and, because it relates to the revenue derived by the electric utility. The term demand side management (DSM) refers to modification of power system demand by some means in order to obtain better load factor characteristics. The study of DSM has many unresolved issues - many stem from the fact that the electric utility industry is …

Frequency Offset Compensation And Burst Design In Frequency Flat Fading Channels, Wen-Yi Kuo, Michael P. Fitz

Department of Electrical and Computer Engineering Technical Reports

Capability to combat channel fading and easy implementation have made the pilot symbol assisted modulation (PSAM) of practical interest in mobile communications. However, the operation in burst mode for multiple access purpose has still been a missing part from previous research. This work first examines the burst design problem associated with pilot symbol allocation in a frequency flat fading environment. Explicit relationship between error performance and the design parameters including pilot distribution, frequency offset, Doppler spread, and modulation scheme is exploreti. A new unequal spacing pilot insertion burst architecture is proposed to achieve better error performance. Frequency offset compensation in …

An Experimental Investigation About The Structure Of International Commerce, Ron Ruey Duh, Shyam Sunder Jan 1994

An Experimental Investigation About The Structure Of International Commerce, Ron Ruey Duh, Shyam Sunder

Purdue CIBER Working Papers

Individual behavior in isolation is known to deviate systematically from predictions of the Bayes' Rule when they are intuitively (i.e., without formal computation). Economic settings, rich in incentives, information and learning, may induce Bayesian behavior. Further, it is possible that the aggregate behavior in markets can be predicted accurately by simply assuming that individuals act as Bayesians. Data from laboratory markets suggest that, compared to specific alternative assumptions about individual information processing, Bayes' Rule is a better predictor of market price but not of allocation and efficiency. Improvement in its performance with trader experience suggests that, as a descriptive theoory …


The Mediating Effects Of Pre- And Post-Assignment Activities On The Quality Of Work Life Of Expatriates: Evidence For Managers In The P.R.C., John Hannon, Ing-Chung Huang, Cheng-Chen Lin Jan 1994

The Mediating Effects Of Pre- And Post-Assignment Activities On The Quality Of Work Life Of Expatriates: Evidence For Managers In The P.R.C., John Hannon, Ing-Chung Huang, Cheng-Chen Lin

Purdue CIBER Working Papers

This study investigates how two managerial interventions, pre-assignment training and post-assignmnet support, mediate the relationship between a set of personal & job characteristics and a broad measure of foreign assignment success, quality of work life (QWL). To accomplish this, we studied 199 expatriates posted form the Republic of China (Taiwan) to the People's Republic of China (PRC), a host ocutnry with a similar language, race, and cultural background. Using this setting, we were better able to isolate the mediating effects of these human resource interventions on the assignee's adjustment and success. In the end, it appears that some of the …
