Self-Calibration Of Parallel-Link Mechanisms, Lixin. Liu Jan 1997

Self-Calibration Of Parallel-Link Mechanisms, Lixin. Liu

Electronic Theses and Dissertations 1990 - 1999

Self-calibration is a desirable feature for an intelligent machine such as a robot that must function outside of controlled laboratory conditions. This is because it is inevitable that variations in the kinematic model arise from imperfections in the manufacturing process and changes of environment conditions. Self-calibration has the potential of (a) removing the dependence on external pose sensing, (b) producing high accuracy measurement data over the entire workspace of the system with an extremely fast measurement rate, (c) being automated and completely non invasive, (d) facilitating on-line accuracy compensation, and (e) being cost effective. This dissertation concentrates on the study …

Senescent And Early Diagenetic Changes In Chlorophyll, Jie Li Jan 1997

Senescent And Early Diagenetic Changes In Chlorophyll, Jie Li

Electronic Theses and Dissertations 1990 - 1999

Aged unispecific cultures and environmental samples have been analyzed using HPLC-PDA in order to reveal chlorophyll-a degradation processes. Unispecific aging studies showed that alteration of chlorophyll occurred during senescence, and revealed that chlorophyll-a breakdown differs amongst various groups (i.e. species specificity). Sediment trap and sediment studies reveal that a variety of precursor chlorophyll-a derivatives are present, and that senescence and geochemistry, per se, overlap strongly. Many of the reactions in the Treibs' scheme occur before and during deposition. Intracellular senescence and diagenetic pathways have been examined in this work. Comparison of aged unispecific cultures and environmental samples strongly suggests major …

Active-Vision-Based Method For Autonomous Navigation, Erkut Erhan Ergen Jan 1997

Active-Vision-Based Method For Autonomous Navigation, Erkut Erhan Ergen

Electronic Theses and Dissertations 1990 - 1999

This research explores the existing active-vision-based algorithms employed in today's autonomous navigation systems. Some of the popular range finding algorithms are introduced and presented with examples. In light of the existing methods, an active-vision-based method, which extracts visual cues from a sequence of 2D images, is proposed for autonomous navigation. The proposed algorithm merges the method titled 'Visual Threat Cues (VTCs) for Autonomous Navigation' developed by Kundur (1), with the structured-light-based methods. By combining these methods, a more practical and a simpler method for indoors autonomous navigation tasks is developed. A textured-pattern, which is projected onto the object surface by …

All The Kaiser's Men: German Volunteers And The Great War, 1914-1918, Michael Brian Petersen Jan 1997

All The Kaiser's Men: German Volunteers And The Great War, 1914-1918, Michael Brian Petersen

Electronic Theses and Dissertations 1990 - 1999

Since its end, scholars and historians have viewed World War I primarily in terms of its impact upon the military and diplomatic spheres of European life and have also made attempts to determine responsibility for starting the war. What has been largely ignored is the plight of those who did the fighting--especially German volunteer soldiers. These young men enlisted in the war effort because of a concrete set of assumptions that were later radicalized during the war experience, which was characterized by seemingly endless labor and episodic periods of extreme violence. This transformation of beliefs had a profound impact upon …

Applications Of Evolutionary Algorithms In Mechanical Engineering, Kevin M. Nelson Jan 1997

Applications Of Evolutionary Algorithms In Mechanical Engineering, Kevin M. Nelson

Electronic Theses and Dissertations 1990 - 1999

Many complex engineering designs have conflicting requirements that must be compromised to effect a successful product. Traditionally, the engineering approach breaks up the complex problem into smaller sub-components in known areas of study. Tradeoffs occur between the conflicting requirements and a sub-optimal design results. A new computational approach based on the evolutionary processes observed in nature is explored in this dissertation. Evolutionary algorithms provide methods to solve complex engineering problems by optimizing the entire system, rather than sub-components of the system. Three standard forms of evolutionary algorithms have been developed: evolutionary programming, genetic algorithms and evolution strategies. Mathematical and algorithmic …

Balanced Hypercube: A Versatile Cube-Based Multicomputer System, Ke. Huang Jan 1997

Balanced Hypercube: A Versatile Cube-Based Multicomputer System, Ke. Huang

Electronic Theses and Dissertations 1990 - 1999

We propose the balanced hypercube (BH), which is a variant of the standard hypercube (Q), as a multicomputer topological structure. An n-dimensional balanced hypercube BHn has the same desirable topological properties of the 2n-dimensional standard hypercube Q2n such as size (2^2n nodes and n2^2n edges), regularity and symmetry, connectivity (2n node-disjoint pathes between any pair of nodes), and diameter (2n when n = 1 or n is even). Moreover, BHn has smaller diameter (2n-1) than Qn's (2n) when n is odd other than 1. In addition, BHn is load balanced, i.e., for every node v of BHn, there exists another …

Calibration Of Seepage From Steady State Simulation For Water Budget Estimation, Angela Alvarez Prymas Jan 1997

Calibration Of Seepage From Steady State Simulation For Water Budget Estimation, Angela Alvarez Prymas

Electronic Theses and Dissertations 1990 - 1999

Water gain/loss through seepage in the Everglades Nutrient Removal (ENR) project is a major component of the water budget. Seepage is the most difficult component to evaluate because most of its constituents cannot be directly measured. For this reason simulations from models or equations are the common procedure to estimate seepage. These procedures involve a series of assumptions and simplifications (i.e., geometry, soil parameters), which can be validated with a calibration-verification process. The accuracy of the water budget for this wetland treatment is very important because it will help to clarify and quantify, together with the nutrient mass budgets, the …
