Noise Control And Speech Intelligibility Improvement Of A Toll Plaza, Luc Mongeau, Robert J. Bernhard, Jeffery P. Feist Jan 2002

Noise Control And Speech Intelligibility Improvement Of A Toll Plaza, Luc Mongeau, Robert J. Bernhard, Jeffery P. Feist

JTRP Technical Reports

Vehicular toll roads are one component of many municipal transportation systems. Open communication windows, often used in tollbooths, facilitate essential communication and monetary transactions. However, the vehicle noise generated outside the booth is easily transmitted into the booth via the open window. Personnel working at toll collection plazas are exposed to extended, continuous traffic noise. Sustained noise levels of this nature may cause hearing loss, induce fatigue or stress, and reduce worker productivity. The annoyance and discomfort related to continuous noise exposure may create an unpleasant working condition and may affect the hospitality of the tollbooth operators and their attitude …


Performance-Related Specifications For Concrete Bridge Superstructures, Volume 1: Performance Parameters And Related Procedure For Concrete Bridge Superstructures, J. A. Ramirez, Jhon Paul Smith Jan 2002

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 1: Performance Parameters And Related Procedure For Concrete Bridge Superstructures, J. A. Ramirez, Jhon Paul Smith

JTRP Technical Reports

In Volume 1 of the final report, the identification of performance levels and parameters, and the development of acceptance criteria, have been addressed. Emphasis has been placed on the development of a methodology for a Performance Related Specification, PRS, for concrete bridge superstructures. The implementation of the methodology, presented in the form of a user-friendly computer program, is project specific. It requires the mean and standard deviation (or definition of a probability distribution) of the input parameters for the performance predictive models. This is done for both the as-designed condition and the as-built condition of the structure. The contractor is …


Performance-Related Specifications For Concrete Bridge Superstructures, Volume 4: Bond Of Epoxy-Coated Bars With Thicker Coatings, J. A. Ramirez, Michael K. Appelhans Jan 2002

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 4: Bond Of Epoxy-Coated Bars With Thicker Coatings, J. A. Ramirez, Michael K. Appelhans

JTRP Technical Reports

In Volume 4 of the final report, the results of an evaluation of the bond performance of epoxy-coated bars with a coating thickness up to 18 mils are presented. The experimental work on the bond performance of epoxy-coated bars with thickness up to 18 mils indicates that the current AASHTO requirements for development length of epoxy-coated bars up to #8 could be safely extended to coating thickness of up to 18 mils. Thus, no change to the bond specifications is recommended in order to implement the use of bars with diameters up to a #8 with epoxy-coating thickness up to …


Performance-Related Specifications For Concrete Bridge Superstructures, Volume 3: Nonmetallic Reinforcement, Robert J. Frosch, Christopher P. Mosley, Ahmet Koray Tureyen Jan 2002

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 3: Nonmetallic Reinforcement, Robert J. Frosch, Christopher P. Mosley, Ahmet Koray Tureyen

JTRP Technical Reports

In Volume 3 of the final report, research work conducted to investigate the behavior of fiber reinforced polymer (FRP) reinforcement is summarized. This study focused on the behavior of FRP reinforced concrete structures with an emphasis on bond and shear. For the bond investigation, three series of beam splice tests were performed on specimens reinforced with steel, glass FRP, and aramid FRP to determine the effect of the different types of reinforcement on bond, cracking, and deflections. The test results indicate that the use of FRP reinforcement leads to lower bond strengths and, therefore, require longer development lengths. The specimen …


Physics Conference Proceedings And The Electronic Environment—An Investigation Of New Dissemination Patterns., Michael Fosmire Dec 2001

Physics Conference Proceedings And The Electronic Environment—An Investigation Of New Dissemination Patterns., Michael Fosmire

Libraries Research Publications

The electronic publication of articles from physics conference proceedings on the arXive preprint server and on dedicated conference web sites is investigated. Several subdisciplines within physics were sampled. Except for high-energy theory conferences, and to a lesser extent astrophysics, there is almost no publication of proceedings articles on the preprint server. Only one conference out of all those sampled had a web site with conference presentations on it. That web site contained audio files of the presentations and images of the overheads used and thus had much different content than the published proceedings.


Bibliographic Instruction In Physics Libraries: A Survey Of Current Practice And Tips For Marketing Bi, Michael Fosmire Dec 2001

Bibliographic Instruction In Physics Libraries: A Survey Of Current Practice And Tips For Marketing Bi, Michael Fosmire

Libraries Research Publications

A survey of physics librarians reveals that undergraduate physics majors rarely receive formal bibliographic instruction, despite a perception that those students are using many kinds of library resources. In addition, less than half of the responding institutions gave any formal instruction to graduate students. Some institutions have been successful in creating library instruction programs in physics, however. The kinds of instruction given are described, and tips from respondents of how to maximize the chances of obtaining instruction opportunities from faculty are shared.


New Techniques For The Design Of Diffractive Optical Devices For Optical Communications And Networking, Pojamarn Pojanasomboon, Okay K. Ersoy Dec 2001

New Techniques For The Design Of Diffractive Optical Devices For Optical Communications And Networking, Pojamarn Pojanasomboon, Okay K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

Three new techniques are proposed for the design of optical devices for various applications in optical communications and networking. The first algorithm shows that the nonperiodic grating-assisted directional coupler design can achieve not only the complete power transfer but also superior performances over the conventional periodic grating-assisted directional coupler in nonsynchronous waveguides. The second method is the newly proposed angular spectrum and beam propagation methods using the continuous and discrete sine transforms. This alternative approach is useful especially when the boundary conditions need to be zeroes, for example at the dielectric-metal interfaces. Lastly, the ranked phased-array method @PAM) helps achieve …

Language, Vagueness, And Social Communication, Colin B. Grant Dec 2001

Language, Vagueness, And Social Communication, Colin B. Grant

CLCWeb: Comparative Literature and Culture

In his paper, "Language, Vagueness, and Social Communication," Colin B. Grant adopts an interdisciplinary approach to an interrelated complex of language, communication, and society. Grant operates with a modified concept of vagueness as a pragmatic property and attempts to establish a link between pragmatic vagueness and contingency in communication. This communicative contingency takes the form of improbabilities (entropy). Grant observes that the challenge lies in modelling communication as porous networks which nonetheless enable society to function. In this sense, contingency in communication must not be confused with arbitrariness just as cognitive closure cannot be confused with solipsism. This line of …

A Study Of The Effect Of Reception Of Works Of Art Through An Interactive Cd-Rom, László Halász, Károly Hantos, Balázs Faa Sep 2001

A Study Of The Effect Of Reception Of Works Of Art Through An Interactive Cd-Rom, László Halász, Károly Hantos, Balázs Faa

CLCWeb: Comparative Literature and Culture

In their article, "A Study of the Effect of Reception of Works of Art through an Interactive CD-ROM," Halász, Hantos, and Faa collected data on the aesthetic impact of art objects through multimedia. They constructed a CD-ROM out of various images, sounds and text. Items were offered to 135 secondary school subjects in the framework of directed interactive polychrome variations. The effect was studied partly by measuring viewing (reading) times for each item, and partly by semantic differential and attitude scales. The data for viewing time and phases, and of items of the semantic differential and attitude scales were analyzed …

Literary Careers: Breaks And Stalls, W. Ray Crozier Sep 2001

Literary Careers: Breaks And Stalls, W. Ray Crozier

CLCWeb: Comparative Literature and Culture

In his article, "Literary Careers: Breaks and Stalls," W. Ray Crozier argues that biographical evidence points to considerable individual variation in writers' output over the life span even when allowance is made for longevity and length of writing career. This issue has been neglected by psychological accounts of creativity. Crozier outlines a theoretical framework for understanding variation in terms of an "artistic career." This is conceptualised as a sequence of projects, the success of which are influenced by intra-project factors such as the rewardingness and difficulties of literary projects and extra-project factors such as work pressures, poverty, and competing demands …
