Best Practices For Winter Maintenance Roadway Deicer Applications In The State Of Nebraska, Tregan Pd Albers Ii
Best Practices For Winter Maintenance Roadway Deicer Applications In The State Of Nebraska, Tregan Pd Albers Ii
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
The cost of deicing chemicals is a significant part of the Nebraska Department of Road’s winter maintenance budget. The objectives of this research are to review literature to determine current winter maintenance practices, analyze and present information gathered in a survey of winter maintenance professionals across Nebraska, and correlate this information with data obtained via MDSS (Maintenance Decision Support System) software to determine current practices being used in the state of Nebraska. Best practices for winter maintenance deicer applications for rural city and county officials in Nebraska are recommended. An explanation of the development of the survey that winter maintenance …

Books/Book Chapters
This book chapter discusses the syntheses of various nanomaterials, for green nanotechnology applications in detail. Special attention is given to the development of emerging areas, such as environmental as well as energy materials. Various approaches for preparing nanostructured photocatalysts, such as titanium dioxide, zinc oxide, iron oxide, and metal sulfides, different conventional methods and novel methods, including sol-gel methods, hydrothermal methods, microwave-assisted methods and sonochemical methods are introduced. The use of nanomaterials as photocatalysts, supporting materials for solar cells, and disinfectants is reported for environmental remediation and energy applications. Advanced applications of nanomaterials for water detoxification, air purification, and the …

Sparse Equation-Eigen Solvers For Symmetric/Unsymmetric Positive-Negative-Indefinite Matrices With Finite Element And Linear Programming Applications, Hakakizumwami Birali Runesha
Civil & Environmental Engineering Theses & Dissertations
Vectorized sparse solvers for direct solutions of positive-negative-indefinite symmetric systems of linear equations and eigen-equations are developed. Sparse storage schemes, re-ordering, symbolic factorization and numerical factorization algorithms are discussed. Loop unrolling techniques are also incorporated in the coding to enhance the vector speed. In the indefinite solver, which employs various pivoting strategies, a simple rotation matrix is introduced to simplify the computer implementation. Efficient usage of the incore memory is accomplished by the proposed "restart memory management" schemes. A sparse version of the Interior Point Method, IPM, has also been implemented that incorporates the developed indefinite sparse solver for linear …
