Development Of Load And Resistance Factor Design For Ultimate And Serviceability Limit States Of Transportation Structure Foundations, Rodrigo Salgado, Sang Inn Woo, Dongwook Kim

JTRP Technical Reports

Most foundation solutions for transportation structures rely on deep foundations, often on pile foundations configured in a way most suitable to the problem at hand. Design of pile foundation solutions can best be pursued by clearly defining limit states and then configuring the piles in such a way as to prevent the attainment of these limit states. The present report develops methods for load and resistance factor design (LRFD) of piles, both nondisplacement and displacement piles, in sand and clay. With the exception of the method for design of displacement piles in sand, all the methods are based on rigorous …

Analysis Of Indot Current Hydraulic Policies, Venkatesh Merwade, Sanjiv Kumar

JTRP Technical Reports

Hydraulic design often tends to be on a conservative side for safety reasons. Hydraulic structures are typically oversized with the goal being reduced future maintenance costs, and to reduce the risk of property owner complaints. This approach leads to a conservative design with higher construction costs. Therefore, there is a need to quantify the cost-benefit aspect of this conservative approach. Accordingly, the overall objective of this project is to compare hydraulic design policies of Indiana Department of Transportation (INDOT) with that of other states, and perform cost-benefit analysis of large versus smaller hydraulic structures in terms of capital and maintenance …

Analysis Of Change Orders In Geotechnical Engineering Work At Indot, Varenya Kumar Duvvuru Mohan, Monica Prezzi, Bob Mccullouch

JTRP Technical Reports

Change orders represent a cost to the State and to tax payers that often extremely large because contractors tend to charge very large amounts to any additional work that deviates from the work that was originally planned. Therefore, efforts must be made to reduce the occurrence of change orders in order to provide significant cost savings to the state of Indiana and save taxpayer dollars. The proposed research, in this context, developed a set of guidelines to allow the geotechnical office of the Indiana Department of Transportation (INDOT) to minimize the probability of having geotechnical change orders, based on analysis …

Procurement Procedures And Specifications For Performance Measure Capable Traffic Infrastructure Data Collection Systems, Christopher M. Day, Thomas M. Brennan Jr., Joseph M. Ernst, Jim Sturdevant, Darcy M. Bullock

JTRP Technical Reports

Traffic signal systems represent a substantial component of the highway transportation network in the United States. It is challenging for most agencies to find engineering resources to properly update signal policies and timing plans to accommodate changing traffic demands. Upgrading existing systems can achieve incremental benefits, but do not address the fundamental problem that information about system performance is not communicated to the agency in a meaningful or systematic way. This project developed a collaborative pilot deployment partnership between a large public agency, university, and commercial equipment manufacturers to define an architecture for a centralized traffic signal management system that …

Recovering Full Repair Costs Of Indot Infrastructure Damaged By Motor Vehicle Crashes, Grant D. Farnsworth, Thomas M. Brennan Jr., Darcy M. Bullock

JTRP Technical Reports

There are approximately 4,000 instances per year where state property located along Indiana Department of Transportation (INDOT) maintained right-of-way needs to be replaced or repaired due to motor vehicle crashes. INDOT incurs significant financial losses to repair state property damage that is not recovered from the responsible driver because responsible parties can not be identified and invoices do not reflect the fully-loaded cost of the repair. This study’s objective is to identify enhanced management procedures to decrease the financial burden of the state by identifying best practices supporting the following four goals: 1) increasing the percent of invoices collected, 2) …

Identification And Behavior Of Collapsible Soils, Alain El Howayek, Pao-Tsung Huang, Rachael Bisnett, Maria C. Santagata

JTRP Technical Reports

Loess is a soil that can exhibit large deformations upon wetting. Cases of wetting induced collapse in loess have been documented for natural deposits and man-made fills. These issues are of concern to the Indiana DOT due to the growth of the state’s infrastructure in regions with significant loess deposits.

The research reviewed the existing literature on loess, focusing on index properties, structure, mineralogy, criteria used for quantifying collapsibility, methods for measuring collapse potential, and, in particular, the collapsibility of compacted loess. Additionally, available documentation on loess deposits in Indiana was reviewed and summarized.

This research also included experimental work …

Truck Travel Characteristics As An Indicator Of System Condition And Performance, Anwaar Ahmed, Mathew Volovski, Daniel Van Boxel, Samuel Labi, Kumares C. Sinha

JTRP Technical Reports

The effect of trucks on the level of service is determined by considering passenger car equivalents (PCE) of trucks. The Highway Capacity Manual (HCM) uses a single PCE value for all tucks combined. However, the composition of truck traffic varies from location to location; therefore a single PCE-value for all trucks may not correctly represent the impact of truck traffic at specific locations. Consequently, the Indiana Department of Transportation wanted to develop separate PCE values for single-unit and combination trucks to replace the single value provided in the HCM. Traditionally, equivalent delay and microscopic simulations have been used to estimate …

Post-Processing Techniques To Enhance Reliability Of Assignment Algorithm Based Performance Measures, Srinivas Peeta, Amit Kumar, Sushant Sharma

JTRP Technical Reports

This study develops an enhanced transportation planning framework by augmenting the sequential four-step planning process with post-processing techniques. The post-processing techniques are incorporated through a feedback mechanism and aim to improve the stability and convergence properties of the solution, thereby improving the reliability of the planning process. There are three building blocks of the proposed post-processing module: slope-based multi-path algorithm or SMPA, perturbation assignment, and O-D prioritization technique. SMPA is the most important part of the module and it can be used as both a post-processing algorithm and an independent static traffic assignment algorithm. In addition to SMPA, the post-processing …

High Performance Concrete Pavement In Indiana, Tommy E. Nantung

JTRP Technical Reports

Until the early 1990s, curling and warping of Portland cement concrete pavement did not concern pavement engineers in many transportation agencies. Since beginning construction of the interstate system in the United States in the late 1950s through the late 1980s, the performance of Portland cement concrete pavement has been associated with properties of concrete as a pavement material. In those years developed standards and design guidelines emphasized better concrete materials and construction control. At the time, combining curling and loading stresses was quite controversial due to the nature of the load-carrying capacity of concrete pavement and the occurrence of types …

Long-Term Behavior Of Integral Abutment Bridges, Robert J. Frosch, Matthew D. Lovell

JTRP Technical Reports

Integral abutment (IA) construction has become the preferred method over conventional construction for use with typical highway bridges. However, the use of these structures is limited due to state mandated length and skew limitations. To expand their applicability, studies were implemented to define limitations supported by rational analysis rather than simply engineering judgment. Previous research investigations have resulted in larger length limits and an overall better understanding of these structures. However, questions still remain regarding IA behavior; specifically questions regarding long-term behavior and effects of skew. To better define the behavior of these structures, a study was implemented to specifically …

The Genesis Of The Gats (General Agreement On Trade In Services), Juan A. Marchetti, Petros C. Mavroidis

Faculty Scholarship

The Uruguay Round services negotiations saw the light of day amidst pressures from lobbies in developed countries, unilateral retaliatory actions, and ideological struggle in the developing world. The final outcome, the GATS, certainly characterized by a complex structure and awkward drafting here and there, is not optimal but is an important first step towards the liberalization of trade in services. This article traces the GATS negotiating history, from its very beginning in the late 1970s, paying particular attention to the main forces that brought the services dossier to the multilateral trading system (governments, industries, and academics), and the interaction between …

The I Of The Beholder, Grady B. Manus

Theses

The essay that follows is an overview of some of the writers and schools of poetics that have influenced my poetry and writing process. A writer's voice echoes their philosophy about the art and the voices of those whose work they most appreciate. I have tried to credit those influences and describe, in brief, my approach to poetry.

My belief is that all art should be exercises in experimentation. Stretching strengthens a poet's work and the art. Poetry is a living thing and it must move and breathe and grow or it will simply cease to be a viable force. …

Using A Flow-Chart To Reduce Juror's Pre-Existing Biases In Cases Utilizing The Insanity Defense, Lauren M. Schlumper

College of Graduate Studies: Theses & Dissertations

Many people believe that the insanity defense is used to avoid responsibility for committing a crime and that it returns dangerous individuals back to the streets. Due to the fact that it is difficult to separate such pre-existing attitudes from evidence presented throughout the trial, many jurors use their attitudes to assist them when deciding a verdict and punishment. For example, Steblay, Hosch, Culhane & McWethy (2006) found that not only is it difficult for jurors to disregard information that is not relevant or presented during trial, but that pre-trial information and attitudes can actually influence their verdict. The present …

Full-Newton-Step Interior-Point Method For The Linear Complementarity Problems, H.K. Pubudu Kaluarachchi

College of Graduate Studies: Theses & Dissertations

In this thesis, we present a new Interior-Point Method (IPM) for monotone Linear Complementarity Problem (LPC). The advantage of the method is that it uses full Newton-steps, thus, avoiding the calculation of the step size at each iteration. However, by suitable choice of parameters the iterates are forced to stay in the neighborhood of the central path, hence, still guaranteeing the global convergence of the method under strict feasibility assumption. The number of iterations necessary to find 2-approximate solution of the problem matches the best known iteration bounds for these types of methods. The preliminary implementation of the method and …

The preliminary investigations of the project focused on the combustion performance and thermal efficiency of peanut FAME and its …

Drift And The Risk-Free Rate, Anda Gadidov, M. C. Spruill

Faculty Articles

It is proven, under a set of assumptions differing from the usual ones in the unboundedness of the time interval, that, in an economy in equilibrium consisting of a risk-free cash account and an equity whose price process is a geometric Brownian motion on [0,∞), the drift rate must be close to the risk-free rate; if the drift rate μ and the risk-free rate r are constants, then r = μ and the price process is the same under both empirical and risk neutral measures. Contributing in some degree perhaps to interest in this mathematical curiosity is the fact, based …

Gender Recognition And Appearance Description In Unconstrained Images Of Human Body, Qin Wu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gender recognition has many useful applications, ranging from business intelligence, through to image search and social activity analysis. Traditional research on gender recognition focuses on face images in a constrained environment. In this work, we propose a novel problem of gender recognition in articulated human body images acquired from an unconstrained environment in the real world. Our empirical study answers the question of whether gender recognition can be performed in articulated body images, and discovers important issues such as which body parts are informative, how many body parts are needed to combine together, and what representations are good for articulated …

And I want to thank Paul for bringing me back …

Secret Inventions, Jonas Anderson

Scholarly Articles in Law Reviews & Journals

Patent law - and innovation policy more generally - has traditionally been conceptualized as antithetical to secrecy. Not only does the patent system require inventors to publicly disclose their inventions in order to receive a patent, but various patent doctrines are designed to encourage inventors to forego trade secrecy. This Article offers a critique of the law’s preference for patents. In particular, this Article examines whether and under what circumstances the law should prefer patents over secrets, and vice versa.

As an initial step towards a theoretically-supported system of inventor incentives, this Article constructs a framework that attempts to balance …

Interpretation Of Well Test Data From Two Hydraulically Communicating Reservoirs, Bander Ibrahim Al Quaimi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Naturally fractured reservoirs (NFR) have been receiving more attention than ever since the beginning of the last decade due to various reasons. The current understanding is not sufficient to achieve a favorable recovery factor due to the complexity associated with the fracture characterization and the dynamic behavior of the fractured system. The majority of the fractured reservoirs are developed. Therefore, before proceeding into secondary or possibly tertiary recovery processes a thorough understanding must be reached to avoid undesirable results. The huge reserve volume present in fractured oil and gas reservoirs motivate engineers, researchers, and geoscientists to exert additional efforts to …

Impact Of Gas Desorption On Production From Multiply Fractured Horizontal Well In Shale, Abdallah O. Arwishad

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, the exploitation of unconventional gas reservoirs has become increasingly important to North American energy supply. Unconventional gas development depends on effective stimulation of low permeability reservoir by creating multiple hydraulic fractures which connects massive reservoir area to the wellbore. Hydraulic fracturing and horizontal drilling are primary techniques to obtain economical production from the shale gas reservoir. In addition to that, gas desorption can be a significant source of gas production in shale gas reservoirs.;This research will illustrate the impact of gas desorption on production from multiply fractured horizontal well in shale by using a reservoir model. This …

Merger Simulation In An Administrative Context, Jonathan Baker

Scholarly Articles in Law Reviews & Journals

This article addresses the application of the economic literature on merger simulation to the practical context of antitrust enforcement. It highlights the value of simple simulations as a basis for creating screens and presumptions – particularly the gross upward pricing pressure index for the preliminary review of unilateral effects among sellers of branded consumer products and a presumption based on identifying mavericks for the analysis of coordinated effects – in order to provide guidance to merging firms and judges, who may not have specialized competition policy expertise. The article explains why antitrust agencies should rely on these approaches to identify …
