Integrating Color, Texture, And Geometry For Image Retrieval, Nicholas Howe, Daniel P. Huttenlocher Jan 2000

Integrating Color, Texture, And Geometry For Image Retrieval, Nicholas Howe, Daniel P. Huttenlocher

Computer Science: Faculty Publications

This paper examines the problem of image retrieval from large, heterogeneous image databases. We present a technique that fulfills several needs identified by surveying recent research in the field. This technique fairly integrates a diverse and expandable set of image properties (for example, color, texture, and location) in a retrieval framework, and allows end-users substantial control over their use. We propose a novel set of evaluation methods in addition to applying established tests for image retrieval; our technique proves competitive with state-of-the-art methods in these tests and does better on certain tasks. Furthermore, it improves on many standard image retrieval …

Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar Jan 2000

Effects Of Wheel Traffic Porosity And Compaction Of Soil Profile, Cevdet Şeker, A. Ali̇ Işildar

Turkish Journal of Agriculture and Forestry

The aim of this experimental study was to determine the effect on soil porosity and compaction of the number of the tractor passes on the soil surface. The soil has a sandy loam texture. A tractor passed once, twice, and four times while the water content of soil was near field capacity. Numbers of tractings increased soil bulk density and compaction, and decreased total porosity, void ratio, air porosity and drainage porosity. One and two tractor passes did not markedly affect the percentage of porosity kept at field capacity porosity, but four tractor passes improved it.

Comparison Of The Swelling And Shrinkage Characteristics Of Corcisan Pine (Pinus Nigra Var. Mantima), İlker Usta, Ari̇f Güray Jan 2000

Comparison Of The Swelling And Shrinkage Characteristics Of Corcisan Pine (Pinus Nigra Var. Mantima), İlker Usta, Ari̇f Güray

Turkish Journal of Agriculture and Forestry

The objective of this study was to determine the volumetric swelling and shrinkage characteristics of air-dried Corsican pine in the longitudinal, tangential and radial directions. For this purpose, the swelling of the wood was caused by the wood being increased in water whilst placed in a swelling jig, and the shrinkage made in an oven by drying. The experimental results showed that although the differences in swelling or shrinking occur in the first 5 hours, both swelling and shrinkage are then negligible in the three directions. The values of swelling-shrinkage showed considerable difference among different directions; for instance, swelling-shrinkage in …

Adieu To Electrocution, Deborah W. Denno Jan 2000

Adieu To Electrocution, Deborah W. Denno

Faculty Scholarship

This Article contends that there is no moral or legal reason to retain electrocution, particularly because other execution methods are available. It is clear that at some point soon, electrocution will no longer exist in this country and, as a result, throughout the world. By eliminating this perplexing vestige, the other problems with the death penalty may appear all that more offensive.

A Field Study Of Scour Monitoring Devices For Indiana Streams, Thomas J. Cooper, Huey-Long Chen, Dennis A. Lyn, A. Ramachandra Rao, A. G. Altschaeffl

JTRP Technical Reports

INDOT is considering the deployment of fixed scour-monitoring instrumentation as part of a systematic response to the problem of scour around bridge piers. Fixed-in-place automated scour-monitoring devices measure the depth of scour at the point where they are installed. Unless they are installed at the location where maximum scour occurs, their readings may give a misleading estimate of scour potential. This raises a number of technical issues concerning their effective deployment and the interpretation of the collected data, which should be resolved in order to maximize the benefits to INDOT from using these monitoring devices. These include the location of …

Development Of Closed Loop System Evaluation Equipment And Procedures, Eric J. Nelson, Montasir Abbas, Gary E. Shoup, Darcy M. Bullock

JTRP Technical Reports

Modern traffic control systems are complex entities whose performance should be thoroughly quantified prior to deployment. However, many of the advanced features available with this control equipment, such as preemption and real-time control strategies, are typically proprietary in nature, and therefore not incorporated into standard simulation models. Since it is not desirable for the engineer to learn in a field environment, under live traffic conditions, this research presents a rational procedure for evaluating and validating such control strategies in a laboratory setting. This document explores three aspects of traffic signal systems, which include the advanced control settings for single controller …

Field Implementation Of Bioremediation At Indot Facilities-Phase I, Loring F. Nies, Brett Robert Baldwin, Matthew B. Mesarch

JTRP Technical Reports

Bioremediation is often the most cost-effective and successful technique available for the remediation of soils and groundwater contaminated with organic pollutants (e.g. petroleum). The goal of bioremediation is to stimulate naturally occurring microorganisms to biodegrade the contaminants to harmless products. To be in compliance with EPA regulations all underground fuel storage tanks must have spill, leak and corrosion protection. Many older obsolete tanks had deteriorated to the extent that petroleum products had leaked into the environment. In the past, petroleum contaminated soils were typically excavated, followed by landfilling of the contaminated material. The continued use of landfills for disposal of …

Monitoring Of Long-Term Performance Of Highway Bridge Columns Retrofitted By Advanced Composite Jackets In Indiana, Ming-Hung Teng, Elisa D. Sotelino, Wai-Fah Chen

JTRP Technical Reports

The service life of highway bridges is limited by the deterioration of their substructure components. In the U.S., it is estimated that more than 240,000 (about 40%) of the highway bridges are functionally or structurally deficient. Repairing these deteriorated bridges using traditional methods is usually time-consuming and expensive. Furthermore, these methods are such that they can cause a number of problems, such as being a threat to public safety and severe traffic disruption. Thus, it is important that new safer and more efficient methods be developed. Fiber Reinforced Plastics (FRP) have a great potential to provide such a solution. Due …
