Finite Element Model Of Nitrogen Species Transformation And Transport In The Unsaturated Zone, Jagath J. Kaluarachchi, J. C. Parker Nov 1988

Finite Element Model Of Nitrogen Species Transformation And Transport In The Unsaturated Zone, Jagath J. Kaluarachchi, J. C. Parker

Civil and Environmental Engineering Faculty Publications

A two-dimensional finite element model based on Galerkin's weighted residual approach and incorporating an upstream weighting technique was developed to predict the simultaneous transformation and transport of nitrogen species. The nitrogen cycle used in the analyses assumes first-order rate coefficients for nitrification, denitrification, immobilization and mineralization between the nitrogen species NH +4, NO -3, organic-N and denitrified fractions. The NO -3-N component in the soil solution was assumed to have negligible adsorption on exchange sites while adsorption of NH +4 was assumed to be represented by a Freundlich type nonlinear isotherm ( S = kdCp). The accuracy and validity of …

Load And Resistance Factor Design Of Cold-Formed Stainless Steel Statistical Analysis Of Material Properties And Development Of The Lrfd Provisions, Shin-Hua Lin, Wei-Wen Yu, Theodore V. Galambos Oct 1988

Load And Resistance Factor Design Of Cold-Formed Stainless Steel Statistical Analysis Of Material Properties And Development Of The Lrfd Provisions, Shin-Hua Lin, Wei-Wen Yu, Theodore V. Galambos

CCFSS Library (1939 - present)

INTRODUCTION 1.1 General Remarks The "Allowable Stress Design" method has long been used for the design of steel structures in the United States. 1,2,3 Recently, the probability-based load and resistance factor design (LRFD) criteria have been successfully applied to the structural design of hot-rolled steel shapes and built-up members. 4,5,6 The AISI LRFD Specification is being developed as well for the design of structural members cold-formed from carbon and low alloy steels. 7-17 These design criteria can provide a more uniform degree of structural safety to achieve consistent reliability for different design situations. The probability-based design method is developed on …

Development Of A Combined Quantity And Quality Model For Optimal Unsteady Groundwater Management, Richard C. Peralta, J. Solaimanian, C. L. Griffis Oct 1988

Development Of A Combined Quantity And Quality Model For Optimal Unsteady Groundwater Management, Richard C. Peralta, J. Solaimanian, C. L. Griffis

Civil and Environmental Engineering Faculty Publications

Presented are alternative techniques for including conservative solute transport within computer models for optimizing groundwater extraction rates. Unsteady two-dimensional flow and dispersed conservative solute transport are assumed. Comparisons are made of the practicality of including modified forms of implicit and explicit finite difference solute transport equations within optimization models. These equations can be calibrated and subsequently used within a MODCON procedure. The MODCON modelling procedure consists of an integrated series of five optimization or simulation modules. The procedure is applicable for either an entire aquifer system or for a subsystem of a larger system. The first module, A, computes physically …


1988 Usage Rates And Effectiveness Of Safety Belts And Child Safety Seats In Kentucky, Kenneth R. Agent Oct 1988

1988 Usage Rates And Effectiveness Of Safety Belts And Child Safety Seats In Kentucky, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objective of the survey summarized in this report is to establish 1988 safety belt and child safety seat usage rates in Kentucky to compare to those determined from previous surveys. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.

Statewide usage rates in the 19 cities previously surveyed in 1982 through 1986 showed that both driver safety belt usage and child safety seat and safety belt usage increased significantly in 1988 compared to previous years. The statewide usage rate of safety belts by drivers was 20.5 percent in 1988 compared to …


Analysis Of Accident Data In Kentucky (1983-1987), Kenneth R. Agent, Jerry G. Pigman Oct 1988

Analysis Of Accident Data In Kentucky (1983-1987), Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

Kentucky has a systematic procedure to identify locations that have abnormal rates or numbers of accidents. This procedure utilizes average accident rates and numbers. A primary objective of this study was to determine average accident statistics in Kentucky. An annual safety program for Kentucky, which includes the identification, programming, budgeting, and evaluation of safety projects, is prepared each year. The data presented in this report may be included as the problem identification portion of Kentucky's Annual Highway Safety Plan.

Average and critical accident rates were calculated by highway type for rural and urban highways. A summary of results and recommendations …
