An Efficient Lower Bound Algorithm For Channel Routing, Heng Yi Chao, Mary P. Harper
An Efficient Lower Bound Algorithm For Channel Routing, Heng Yi Chao, Mary P. Harper
Department of Electrical and Computer Engineering Technical Reports
Channel routing plays a central role in the physical design of VLSI chips. For two-layer dogleg-free channel routing, dm,, and v,,, are the two traditional lower bounds. In this paper, we present two efficient algorithms for computing a tighter lower bound for the channel routing problem. Our algorithms succe:j~fullyc ompute a lower bound of 26 for Deutsch's Difficult Example (DDE). The experiment on some large-scale randomly generated channel routing problems sholws that our lower bound algorithms are much tighter than the traditional lower bounds, and are much more efficient than Pals' algorithm [20] while obtaining similar (sometimes better) results.

A Difficult Channel Routing Generator, Heng Yi Chao, Mary P. Harper
Department of Electrical and Computer Engineering Technical Reports
For channel routing problems, Deutsch's examples were used extensively as benchmarks for testing new algorithms. However, it is also extremely important to test the performance of channel routing algorithms on a wider variety of difficult examples. In this paper, we present a random channel routing generator which can generate difficult channel routing instances of arbitrary size.

Behavior Of Concrete Bridge Decks And Slabs Reinforced With Epoxy Coated Steel, Hendy Oetih Hasan, J. A. Ramirez
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 …
Use Of Time Domain Reflectometry For Determination Of Water Content An Density Of Soil, Shafiqul I. Siddiqui, Vincent P. Drnevich
Use Of Time Domain Reflectometry For Determination Of Water Content An Density Of Soil, Shafiqul I. Siddiqui, Vincent P. Drnevich
JTRP Technical Reports
A new method is developed for measuring in-place density and moisture content of soil using the technique of Time Domain Reflectometry (TDR). The method is applicable for construction control of earthworks. The method is extended for measuring moisture content of soil in the laboratory and in the field for various other geotechnical purposes. Laboratory uses include measuring moisture content of soil in compaction molds; field uses include measuring moisture content of soil in Shelby tubes and soil retrieved during drilling and sampling operations. In the course of achieving these goals, this study develops the principles of TDR probe design, test …

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 …
An Evaluation Of Lane Closure Strategies For Interstate Work Zones, Raktim Pal, Kumares C. Sinha
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
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 …
Concrete Pavement Crack And Seat Performance Overlay Design, Haiming Huang, Thomas D. White
Concrete Pavement Crack And Seat Performance Overlay Design, Haiming Huang, Thomas D. White
JTRP Technical Reports
The objective of this study is to develop guidelines and criteria for design and construction of overlays on cracked and seated concrete pavements. The main factors which are investigated in this study include number of the seated roller pass, weight of seating roller pass, weight of seating roller, thickness of overlay, fiber content and fiber layer location. Eleven test sections were constructed on I-65 and twenty two test sections were constructed on US-31. An extensive investigation was conducted involving both field and laboratory testing. Field investigations included pavement condition survey and non destructive testing (NDT) of the pavements using FWD …
Development Of Annual Permit Procedure For Overweight Trucks On Indiana Highways, Robert K. Whitford, David P. Moffett
Development Of Annual Permit Procedure For Overweight Trucks On Indiana Highways, Robert K. Whitford, David P. Moffett
JTRP Technical Reports
Overweight truck permitting in Indiana is presently done on a per trip basis. This study evaluated alternatives to each trip having to make a call to the INDOT permit office to gain a permit. The study was originally requested by the Indiana State Legislature under P.L. 122-1993 section 7 in response to delays in getting permits. The report’s six chapters are 1. Introduction and Summary 2. Review of Other States’ Permitting Systems 3. Framework for Policy Evaluation 4. Permits for Michigan Truck-Trains 5. Overweight and Overweight/Oversized Trucks 6. Implementation Suggestions – PLUS -- 7. Appendices. A Michigan Truck-Train is a …
Fatigue Strength Of Girders With Tapered Covered Plates, Ahmed Farouk Hassan, Mark D. Bowman
Fatigue Strength Of Girders With Tapered Covered Plates, Ahmed Farouk Hassan, Mark D. Bowman
JTRP Technical Reports
This report represents results from a study to determine the fatigue strength of steel beams with welded partial-length cover plates. Results of an experimental investigation that examined the fatigue strength of various cracked cover plate end details that were subsequently repaired are presented. The repair methods investigated included a slip-critical bolted splice plate connection, air-hammer peening, and a combination of the previous two called a partial bolted splice connection. Also, an analytical model was developed to predict the fatigue behavior of a cover plate and detail that is repaired using one of the three repair methods investigated and which contains …
