A Nitrided-Oxide Dielectric For Epitaxial Lateral Overgrowth Applications, William W. Fultz, Gerold W. Neudeck
A Nitrided-Oxide Dielectric For Epitaxial Lateral Overgrowth Applications, William W. Fultz, Gerold W. Neudeck
Department of Electrical and Computer Engineering Technical Reports
Polyoxide gate dielectric degradation problems were encountered during the process development of a three-dimensional CMOS structure. In prior studies, the gate dielectric degradation was found to occur when the polyoxide was exposed to the oxygen deficient, low pressure silicon rich epitaxial lateral overgrowth (ELO) ambient . The durability of thin polyoxide dielectrics is essential to three-dimensional process, allowing bottom gate control of the vertically stacked PMOS load device. The previous process had approximately a 1000 A minimum thickness limit on the bottom gate dielectric, unacceptable when compared to modern day CMOS technology. This research was directed at developing a durable …

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

An Evaluation Of Lane Closure Strategies For Interstate Work Zones, Raktim Pal, Kumares C. Sinha
JTRP Technical Reports
A systematic procedure was developed in the present study that can be used to make a decision regarding the appropriate lane closure strategy at a particular interstate work zone. Four criteria were identified which influence such a decision, namely user travel time and vehicle operating cost, traffic control cost, safety, and contractors’ convenience. The influences of these criteria were aggregated using the Analytic Hierarchy Approach. The procedure developed in the present study is systematic in nature, simple to use and sensitive to the policy adopted by a transportation agency. A computer program, LANECLOSE, was developed which can be readily used …

Asphalt Mix Design And Performance, Shakor Ramat Badaruddin, Thomas D. White
JTRP Technical Reports
Premature flexible pavement distress became a major concern in Indiana. As a result, a study was conducted investigating the major underlying factors. Pavement sections were investigated based on a factorial study with four factors comprised of climate, truck traffic, pavement base type, and wheel path. The distresses evaluated were rutting, thermal cracking and stripping. All were evaluated against control sections with zero distress. The pavement condition of each section was determined. Laboratory tests of field sample included physical properties, dynamic creep and recompaction. Results of the study indicate that the Asphalt Institute mix design criteria identify an asphalt content that …

Behavior Of Concrete Bridge Decks And Slabs Reinforced With Epoxy Coated Steel, Hendy Oetih Hasan, J. A. Ramirez
JTRP Technical Reports
Thirty-four slab specimens with splices and transverse steel were tested in the laboratory to evaluate the structural performance of concrete bridge decks reinforced with epoxy-coated steel. Thirty specimens were tested under fatigue loading, and four were tested monotonically. Evaluations were made by comparing the performance of uncoated bar concrete specimens with that of epoxy-coated specimens under service and ultimate load conditions. In addition, a field evaluation of six bridges was conducted to assess the in-service condition of concrete bridge decks reinforced with epoxy-coated steel in Indiana. The laboratory results indicated fewer but wider cracks in specimens with epoxy-coated reinforcement. No …

Improved Strategies For Deploying Vehicle-Actuated Control At Isolated Signalized Intersections, Michael J. Cassidy, Yu-Hao Chuang, Jeffrey Dunn Vitale
Improved Strategies For Deploying Vehicle-Actuated Control At Isolated Signalized Intersections, Michael J. Cassidy, Yu-Hao Chuang, Jeffrey Dunn Vitale
JTRP Technical Reports
This research has sought to demonstrate potential benefits from deploying enhanced vehicle actuation strategies at isolated signalized intersections. The work has exploited microscopic, stochastic simulation to evaluate impacts of enhanced vehicle-actuated (VA) control schemes for an array of operating conditions. Simulated outcomes (i.e. average vehicle delays) generated under the enhanced strategies were compared with outcomes resulting from more “conventional VA control policies. Findings from this work suggest that substantial delay reduction generally occurs by exploiting VA strategies which seek to 1) facilitate the use of the clearance interval by discharging vehicles, 2) shorten the duration of the required clearance interval …

Effects Of Salt And Trace Minerals For Bituminous Pavement Literature Review, Information Gathering, And Research Plan Development, Robert Allan Pittenger, Terry R. West
Effects Of Salt And Trace Minerals For Bituminous Pavement Literature Review, Information Gathering, And Research Plan Development, Robert Allan Pittenger, Terry R. West
JTRP Technical Reports
A review of current literature on the effects of deicing salt and trace minerals, such as sulfate, on aggregate deterioration was conducted. Such deterioration in both Portland cement concrete, and bituminous pavements was reviewed. For Portland cement concrete, it was determined that current research on the effects of moisture and deicing salt on aggregates concrete matrix durability, with little discussion on the effects on aggregates. The effects of trace minerals in deicing salt are also rarely discussed. Pore size distribution, insoluble residue, absorption, and susceptibility to alkali-silica reaction all appear to affect aggregate durability in the presence of moisture of …
