The various generations of Silicon Vertex Detectors (SVX, SVX', SVXII) for Collider Detector at Fermilab (CDF) at the Fermilab Tevatron have been fundamental tools for heavy-flavor tagging via secondary vertex detection. The CDF Run IIb Silicon Vertex Detector (SVXIIb) has been designed to be a radiation-tolerant replacement for the currently installed SVXII because SVXII was not expected to survive the Tevatron luminosity anticipated for Run IIb. One major change in the new design is the use of a single mechanical and electrical element throughout the array. This element, called a stave, carries six single-sided silicon sensors on each side and …


Secure Group Communication Using Robust Contributory Key Agreement, Y. Amir, Y. Kim, C. Nita-Rotaru, J. L. Schultz, J. Stanton, G. Tsudik Jan 2004

Secure Group Communication Using Robust Contributory Key Agreement, Y. Amir, Y. Kim, C. Nita-Rotaru, J. L. Schultz, J. Stanton, G. Tsudik

Department of Physics and Astronomy Faculty Publications

Contributory group key agreement protocols generate group keys based on contributions of all group members. Particularly appropriate for relatively small collaborative peer groups, these protocols are resilient to many types of attacks. Unlike most group key distribution protocols, contributory group key agreement protocols offer strong security properties such as key independence and perfect forward secrecy. This paper presents the first robust contributory key agreement protocol resilient to any sequence of group changes. The protocol, based on the Group Diffie-Hellman contributory key agreement, uses the services of a group communication system supporting Virtual Synchrony semantics. We prove that it provides both …

Analysis Of A Phase Change Energy Storage System For Pulsed Power Dissipation, S Krishnan, S V. Garimella

CTRC Research Publications

The melting of a phase change material in a container of rectangular cross-section with multiple discrete heat sources mounted on one side is investigated for electronics cooling by latent heat energy storage. This numerical study focuses on the thermal management issues that arise when electronic components experience sudden surges in power dissipation. The transient response of the energy storage system to short pulses in power dissipation is studied. Convective cooling using air-cooled heat sinks on the sides of the containment remote from the heat sources provides for heat rejection to ambient air. The analysis is performed under different pulse frequencies. …

Optimization Of Thermal Interface Materials For Electronics Cooling Applications, Vishal Singhal, Thomas Siegmund, Suresh V. Garimella Jan 2004

Optimization Of Thermal Interface Materials For Electronics Cooling Applications, Vishal Singhal, Thomas Siegmund, Suresh V. Garimella

School of Mechanical Engineering Faculty Publications

Thermal interface materials (TIMs) are used in electronics cooling applications to decrease the thermal contact resistance between surfaces in contact. A methodology to determine the optimal volume fraction of filler particles in TIMs for minimizing the thermal contact resistance is presented. The method uses finite element analysis to solve the coupled thermo-mechanical problem. It is shown that there exists an optimal filler volume fraction which depends not only on the distribution of the filler particles in a TIM but also on the thickness of the TIM layer, the contact pressure and the shape and the size of the filler particles. …

2004 Rosabeth Moss Kanter Award For Excellence In Work-Family Research Publication, Shelley M. Macdermid

Center for Families Publications

Over the past few decades there has been an explosion of research on the relationships between work and non-work life. Researchers studying these issues come from many disciplines and professions, resulting in fragmented awareness of one another's work. In addition, exchanges of research information among scholars, consultants and corporate practitioners are limited. Many research studies are not well-grounded in theory, slowing the generation of new knowledge. As a result, it has been difficult to develop shared standards for research quality and to avoid redundance in the research literature. Some excellent studies have failed to have impact because of lack of …

JTRP Technical Reports

This study is a continuation and the final phase of the SPR-2338 project that involves monitoring the ambient air quality levels adjacent to the Borman Expressway. The purpose of this phase was to classify the traffic conditions along the Borman Expressway in terms of ambient air quality levels. The duration of the phase was from April 1, 2002 to April 30, 2004. The study has shown that, in a close proximity to the Borman Expressway, air quality levels mirror the dynamic nature of traffic along the Borman, despite being surrounded by major industrial stationary sources. Therefore, a descriptive model was …


A Highway Travel Information System: Forecasting And Publicizing Delays In The Indiana State Highway Network, Shu-Ling Yu, Jon D. Fricker Jan 2004

A Highway Travel Information System: Forecasting And Publicizing Delays In The Indiana State Highway Network, Shu-Ling Yu, Jon D. Fricker

JTRP Technical Reports

The Highway Travel Information System (HTIS) is a long-term pre-trip information system providing information about expected events, such as road construction. The HTIS can be beneficial to both highway travelers and roadway project schedulers. Project schedulers can use the HTIS to check the forecasted traffic impacts of a proposed construction project schedule. If the schedule would cause unacceptable delays, a scheduler can try new schedules to reduce the delay. Travelers who have flexible schedules and would like to do pre-trip planning can obtain knowledge of traffic conditions in the near future from HTIS to avoid unnecessary delays. An approach called …

An Analysis Of Cost Overruns And Time Delays Of Indot Projects, Claire Bordat, Bob G. Mccullouch, Samuel Labi, Kumares C. Sinha

JTRP Technical Reports

A commonality among state Departments of Transportation is the inability to complete projects on time and within budget. This project assessed the extent of the problem of cost overruns, time delays, and change orders associated with Indiana Department of Transportation (INDOT) construction projects, identified the reasons for such problems, and finally developed a set of recommendations aimed at their future reduction. For comparison purposes, data from other states were collected and studied using a questionnaire instrument. The analysis of the cost overrun, time delay and change order data was done using an array of statistical methods. The literature review and …

The Development Of A Highway Tort Liability Management System For The Indiana Department Of Transportation, Thomas Giraud, Vorasett Chovichien, Samuel -1962 Labi, Kumares C. Sinha

JTRP Technical Reports

The loss of states’ sovereign immunity in the 1970’s opened the gates for highway-related tort liability suits against the states. Between January 2001 and September 2002, the State of Indiana investigated and settled hundreds of highwayrelated tort cases, involving several millions of dollars in taxpayers’ money. There is a need to assess the frequency of occurrence and financial impacts of such claims, and to examine how the growth of highway tort claims could be arrested. This study aimed at reviewing existing highway tort liability risk management practices at other states for possible applicability to INDOT, developing a framework for managing …
