Log breakdown using dynamic programming and 3-D log shape

Creator:: Zeng, Yimin
Abstract:: A log breakdown model, SAW3D, was developed to optimize lumber recovery from logs of any shape in 3- dimensional space. The program uses a polygonal cross section representation of logs; three nested dynamic programming (DP) algorithms to optimize log breakdown, flitch and cant edging, and trimming operations; and a simple...

Development of a process for fabricating high-aspect-ratio, meso-scale geometries in stainless steel

Creator:: Walker, Benjamin A.
Abstract:: Miniature energy and chemical systems (MECS) are miniature thermal, fluid, and chemical devices in the mesoscale size range between a sugar cube and a human fist. MECS take advantage of improved rates of mass and heat transfer that have been observed at the microscale. There are many potential applications for...

Analysis and modeling of multi-mode effects in coplanar waveguide bends

Creator:: Senguttuvan, Rajarajan
Abstract:: A novel method for modeling bends in coplanar waveguides (CPWs) is described. The CPW can be viewed as a pair of parallel coupled quasi-slot lines. Bends in the CPW are modeled as a non-uniform coupled line system in terms of their even- and odd- mode characteristics. This modeling approach is...

Analysis of iteration schemes for deterministic transport in binary Markovian mixtures

Creator:: Ching, Brenton S.
Abstract:: The Adams-Larsen-Pomraning coupled transport model has been used to describe neutral particle transport in binary stochastic mixtures. Here, the mixing statistics are considered to be homogeneous Markovian processes. While the model is robust, the convergence behavior and efficiency of this coupled model have not been addressed. Countless iterative methods could...

Investigating socio-technical factors in short-term continuous improvement project effectiveness

Creator:: Stelson, Paul Martinez
Abstract:: Lean manufacturing, or more generally continuous improvement (CI), has been the methodology behind significant improvements in quality, work in process inventory reductions, lead time reduction and cost reduction while conversely being associated with failed implementations and occasionally with unpopular work practices. This research focused on promoting understanding of CI methodology...

Image pre-processing algorithms for isolation of defects in Douglas-fir veneer

Creator:: Forrer, Johannes Barry
Abstract:: The goal of this research is to develop automatic techniques for identifying defects in Douglas-fir veneer. To achieve this goal, computer vision techniques, in particular image-processing, will be applied. Several pre-processing steps may be required to enhance images in making further analysis easier, faster, and more reliable. Pre-processing is often...

An examination of relationships between hunting participation, family relations, and adolescent self-concept

Creator:: Baas, John M.
Abstract:: Recreation benefits are improved personal and social conditions which are thought to occur as a result of recreation participation. If these improved conditions can be adequately identified and measured, then they can be applied to recreation policy and planning decisions. Little research has been done on recreation benefits. Much of...

Void fraction variations in a fractal-like branching channel network

Creator:: Cullion, Rebecca
Abstract:: Two-phase flow in a fractal-like branching microchannel heat sink may have enhanced heat transfer capabilities over single phase flow in the same branching channel network. In order to exploit this potential, a complete understanding of flow boiling in this geometry is required. The fractal-like geometry is similar to that of...

Kinetic and modeling investigations of the anaerobic reductive dechlorination of chlorinated ethylenes using single and binary mixed cultures and silicon-based organic compounds as slow-release substrates

Creator:: Yu, Seungho
Abstract:: This study investigated complete reductive dechlorination of chlorinated aliphatic hydrocarbons (CAHs) over a broad range of concentrations. Tetrabutoxysilane (TBOS), as a slow-release anaerobic substrate, was studied for enhanced reductive dechlorination of tetrachioroethylene (PCE) present as a dense non-aqueous liquid (DNAPL). Four different site-mixed cultures were used in the study: Site-300...
