The Conversion of a General Motors Cadillac SRX to Drive-By-Wire Status

Leppin, Leiann Kirkland 26 January 2006 (has links)
In the fall of 2004, the High Speed Autonomous Vehicle Team, a group of 16 students took on the goal of converting a vehicle to drive-by-wire status. The main goal of this project was to convert a Cadillac SRX donated by General Motors, to fully by-wire control. This thesis presents the HSAVT brake-by-wire and the steer-by-wire solution. In addition, the results of a literary search on drive-by-wire systems are presented. The results of the project proved that the team came up with a solid, effective drive-by-wire vehicle and that the project met all of the primary goals of the project. / Master of Science

Evaluation of fisheries by-catch and by-product meals in diets for red drum (Sciaenops ocellatus)

Whiteman, Kasey 12 April 2006 (has links)
By-catch and wastes from processed fish and shrimp constitute a sizeable portion of commercial fishery landings. This discarded material is potentially valuable, for its content of fish meals and other substances. Fish meals, in particular, are increasingly in short supply for the manufacture of animal feeds, including feeds for farmed fish. Therefore, in this study, various by-catch and by-product meals of marine origin were evaluated with red drum (Sciaenops ocellatus), a carnivorous fish species native to the Gulf of Mexico that has been cultured over the past two decades for stock enhancement as well as for food. Four different kinds of by-catch or by-product meals [shrimp by-catch meal, shrimp processing waste meal, red salmon (Oncorhynchus nerka) head meal, and Pacific whiting (Merluccius productus) meal] were substituted for Special Select™ menhaden fish meal at two different levels (33% or 67% of crude protein) in prepared diets for red drum. Another treatment consisted of shrimp processing waste meal formulated on a digestible-protein basis to replace 33% of the protein from menhaden fish meal. Levels of calcium carbonate were reduced in two additional diets containing Pacific whiting, to evaluate the effects of ash content. Diets were formulated to contain 40% crude protein, 12% lipid, and 3.5 kcal digestible energy/g. Each diet was fed to triplicate groups of juvenile red drum in 38-l aquaria containing brackish water (7 ± 1 ppt) in two separate 6-week feeding trials. Survival, weight gain, feed efficiency, protein efficiency ratio and body composition responses were measured in each trial. Fish fed the by-catch meal at either level of substitution performed as well as fish fed the control diet containing protein solely from menhaden fish meal; whereas, fish fed the shrimp processing waste meal diets did significantly (P ≤ 0.05) worse than the controls, even when fed a diet formulated to be equivalent on a digestible-protein basis. Fish fed the red salmon head meal diet fared poorly, probably owing to an excessive amount of lipid in the diet that tended to become rancid. Overall, by-catch meal associated with shrimp trawling appears to be a very suitable protein feedstuff for red drum.

The study of change process targeting privatization in Taiwan Tobacco and Liquor Corporation

Ye, Li-Na 04 August 2003 (has links)
Abstract While Taiwan Tobacco and Wine Bureau transformed into Taiwan Tobacco and Liquor Corporation, the first presidency was selected publicly to account for privatization by Executive Yuan. The new president proposed ¡u123¡vobjectives to be the targets and visions in privatization process. This study observed the influences of the emergent events during change process, analyzed the elements that influenced the objectives, finally proposed some management implications. Thus, there are three stages in this case study: (1) elected critical events in the change process, (2) build the model that influenced the objectives, (3) explored the feasible management action. We divided the change process into different phases, including initiating change , forming top level managers, proposing objectives of management, communicating the vision, creating new competitive advantages, launching new products and implementing social responsibilities. In the wake of 11 critical process events, the¡u123¡vobjectives was becoming impossible. We analyzed the influencing model which composed by three elements: (1) Executive and Legislative Yuan, (2) social and market, (3) employees and union. Furthermore, by in-depth interviewing with selected employees, we found that the success of privatizing transformation and the improvement of competitive advantage not only depend on management by objectives but also rely on the management by value. In summary, from external perspective, the real meaningful management action should focus on building the legitimacy and competitive advantages of corporation. On the other side, from the internal perspective, we suggest the participating management by objective and deep structural management by transferring the value of employee. To effective change management of privatization, we recommend that (1) predict and control only work for short term objectives, (2) the role of leader is the player of context, (3) the change of value is the critical factor of privatization.

Flying qualities and flight control system design for a fly-by-wire transport aircraft

Gautrey, Jim January 1998 (has links)
Fly-by-wire flight control systems are becoming more common in both civil and military aircraft. These systems give many benefits, but also present a new set of problems due to their increased complexity compared to conventional systems and the larger choice of options that they provide. The work presented here considers the application of fly-by-wire to a generic regional transport aircraft. The flying qualities criteria used for typical flying qualities evaluations are described briefly followed by analysis of several past transport aircraft flying qualities programmes against these criteria. From these results, some control law independent design requirements are formulated for a civil aircraft for the approach and landing task. These control law independent flying qualities criteria are intended to be used with any generic rate-like control law for a transport aircraft and enabled a number of different control laws to be designed. The results of a number of flying qualities evaluations are presented. Both an ILS approach task and a formation flying task were used. The effects of windshear were also considered. It was found that control laws which maintain flight path are suitable for the ILS approach task, while most rate-like response characteristics give good flying qualities for the formation flying task. Finally, the conclusions drawn from these evaluations are presented, and both the Civil and Military current airworthiness requirements are assessed. In addition to the flying qualities work, a study is made of the management issues associated with fly-by-wire design. A fly-by-wire aircraft design programme was proposed and the project management issues associated with this were considered. A timescale was proposed for the design process for a generic regional aircraft, and the critical path for this process is presented.

Acid stabilization of autolyzed fish : storage and nutritional characteristics

Culbertson, Jeffry Dean 10 March 1978 (has links)
The effects of ambient temperature storage on the chemical and nutritional characteristics of phosphoric and sorbic acid-stabilized fish autolysates were determined. Variations in sample composition due to autolysis, deboning, and acidification were also evaluated. Autolysates of English sole (Parophrys vetulus), true cod (Gadus macrocephalus), Dover sole (Microstomus pacificus), and orange rockfish (Sebastodes pinniger) carcass wastes, whole Pacific hake (Merluccius productus) and dogfish shark (Squalis acanthias), and a hake/tuna viscera (70/30 wt/wt) mixture were utilized in the investigation. Samples were acidified to ca. pH 3.25 with phosphoric acid (85% w/v) and contained potassium sorbate at the 0.2% (wt/wt) level. Screen separation of bone reduced the ash levels of samples, with the exception of dogfish shark. Loss of bone minerals, specifically calcium and phosphorus, was responsible. Phosphoric acid addition elevated ash and phosphorus contents to higher levels than for raw materials. Acid-stabilized autolysates were stable to microbial outgrowth throughout 8 months of ambient temperature storage. Slight increases in pH levels were generally observed. Sorbate levels decreased at an apparently exponential rate with respect to time (r=-.9146, P [greater than or equal to] .005). Hydrolytic rancidity did not proceed during storage. Stability towards microbial outgrowth, inactivation of endogenous lipases during pasteurization, and maintenance of acidic environmental conditions enhanced fat stability. Oxidative rancidity, as measured by 2-thiobarbituric acid (TBA) numbers, progressed during storage. Carcass wastes showed higher rates and overall levels of oxidation. Initial free fatty acid levels correlated in a linear manner with 0 and 4 month TBA numbers (r=.9548, P [greater than or equal to] .005; r=.9187, P [greater than or equal to] .005, respectively). The regression of TBA numbers at 4 months on zero time values increased in a linear manner (r=.9346, P [greater than or equal to] .005). Proteolysis during storage, as monitored by free amino groups, was not detected. Inactivation of native proteases during processing and the microbial stability of samples were responsible. Levels of available e-amino lysine and tryptophan were stable throughout storage. The protein quality of acidified hake, dogfish shark, orange rockfish, and English sole autolysates, stored for 0, 4, and 8 months, was evaluated using protein efficiency ratio (PER) determinations. Protein quality was not affected by storage in samples of acidified hake, English sole, and orange rockfish (P=.05). Ratios for all samples of hake and the 0 and 8 month samples of dogfish shark did not vary significantly (P=.05) from the casein control. English sole and orange rockfish samples yielded PER values that were inferior to casein and round fish samples (P=.05). The regression of feed consumption and PER values on TBA numbers decreased in a linear manner (r=-.7999, P [greater than or equal to] .005; r=-.8424, P [greater than or equal to] .005, respectively). Higher contents of nutritionally inferior visceral proteins and increased rates of oxidative rancidity in the carcass waste samples probably were responsible for their reduced protein qualities. / Graduation date: 1978
