Utilization Of Evolutionary Algorithms To Improve Engineering Decision - Making, Robert Gerhart
Utilization Of Evolutionary Algorithms To Improve Engineering Decision - Making, Robert Gerhart
Culminating Projects in Mechanical and Manufacturing Engineering
While genetic algorithms have been explored academically, and in at least two known cases, commercialized, they still seem to be an underutilized technique for solving engineering management problems. One of the reasons for this is the general lack of awareness and understanding about genetic algorithms. Another reason is that genetic algorithms have generally been viewed as being too costly in terms of computing resources to implement for complex problems. This paper examines an example management problem and an example genetic algorithm that was developed to solve it in order to illustrate the applicability of such algorithms to similar or more …
Design Of Meta-Materials Outside The Homogenization Limit Using Multiscale Analysis And Topology Optimization, Christopher Czech
Design Of Meta-Materials Outside The Homogenization Limit Using Multiscale Analysis And Topology Optimization, Christopher Czech
All Dissertations
The field of meta-materials engineering has largely expanded mechanical design possibilities over the last two decades; some notable design advances include the systematic engineering of negative Poisson's ratio materials and functionally graded materials, materials designed for optimal electronic and thermo-mechanical performances, and the design of materials under uncertainty. With these innovations, the systematic engineering of materials for design-specific uses is becoming more common in industrial and military uses. The motivation for this body of research is the design of the shear beam for a non-pneumatic wheel. Previously, a design optimization of a finite element model of the non-pneumatic wheel was …

Development Of Novel Solar Tracking And Heat Extracting Technologies, Hassan Latif Hassan
Electronic Thesis and Dissertation Repository
The global energy and water crises are looming due to the exponential population growth and the shrinking reserves of conventional fossil fuels and fresh water. The present research is aimed at the development of novel components/technologies that would lead to efficient and affordable concentrated solar thermal systems. A novel dual-axis solar tracking system has been developed, built and extensively tested on a field parabolic dish solar collector model. The tracker has two main novel components; active dual axis tracker; and load compensator. The tracker is characterized with simplicity and reliability. Two geometries of novel conical thermal receivers were designed, constructed …
Temperature And Strain Controlled Optimization Of Stabilization Of Polyacrylonitrile Precursor Fibers, Mark Parr Taylor
Temperature And Strain Controlled Optimization Of Stabilization Of Polyacrylonitrile Precursor Fibers, Mark Parr Taylor
Theses and Dissertations--Mechanical Engineering
Carbon fiber is one of the leading materials for high strength and modulus, and light weight applications. Improvements in carbon fiber properties are directly dependent on all aspects of manufacture, especially the process of stabilization. Therefore, it is the goal of this thesis to study the effects of the temperature and strain profile of the stabilization process, and the resulting carbon fiber tensile properties. In addition, the precursor fibers used were spun under two different draw ratios, to study the effects of the spinning parameters. Results indicated through DMA studies that completeness of stabilization reactions can be gauged by the …
Feasibility Analysis Of Estrification Systems With Entrainers, Kang Wook Lee
Feasibility Analysis Of Estrification Systems With Entrainers, Kang Wook Lee
Dissertations and Theses
(Ethyl Acetate) and IPA (Isopropyl Acetate) production systems are studied in terms of the feasibility analysis. It is not feasible to retrieve pure products by a simple reactive distillation for IPA production system because CCR (Critical Composition Region) covers the entire desired binary edge for IPA system. On the other hand, even though CCR does not cover the entire desired binary edge of the EA system completely, internal reflux ratio (IRR) analysis does not allow the production of the pure product via reactive distillation for EA production system. To overcome the restraints, external entrainers are utilized to take advantage of …
