Cruise Ship Preliminary Design: The Influence Of Design Features On Profitability, Justin Epstein Dec 2014

Cruise Ship Preliminary Design: The Influence Of Design Features On Profitability, Justin Epstein

LSU New Orleans Theses and Dissertations

This thesis provides a means to estimate the physical and performance characteristics of a preliminary cruise ship design. The techniques utilized to estimate these characteristics are showcased in the user-friendly interface known as the Cruise Ship Analysis Tool (CSAT). Using the CSAT, the implications that design feature decisions in the preliminary design stage have on a cruise ship’s profitability is analyzed. Then, the most profitable design feature assemblage among a finite number of varying design feature combinations is estimated and compared among cruise ship designs with different passenger carrying capacities. Profitability is analyzed using the measure of merit (MOM) known …


Computational Fluid Dynamics Analysis Of An Ideal Anguilliform Swimming Motion, Charles Rogers Dec 2014

Computational Fluid Dynamics Analysis Of An Ideal Anguilliform Swimming Motion, Charles Rogers

LSU New Orleans Theses and Dissertations

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such theory was written by Dr. William Vorus and Dr. Brandon Taravella involving ideal efficiency. It is therefore interesting to test the calculations to see if it is possible to design a motion that can create thrust without necessarily creating vorticity. The computational fluid dynamics software of ANSYS Fluent was used to calculate the resulting flow field of the eel motion to compare with the theoretical values.

Optimised Integration Of Grid-Connected Renewable Energy Technologies For Domestic Application In Ireland, Zhe Li Nov 2014

Optimised Integration Of Grid-Connected Renewable Energy Technologies For Domestic Application In Ireland, Zhe Li

Doctoral

The utilisation of renewable energy resources for electricity and thermal generation is extremely important in Ireland due to the lack of indigenous fossil fuel resources and the high dependence on imported fossil fuels. The release of environmentally-damaging greenhouse gases in the combustion of fossil fuels in electricity and thermal generation is also a major issue. In Ireland, the domestic dwelling is recognised as one of the biggest energy consumers. The use of renewable energy technologies to provide electricity, heating and hotwater can effectively offset the usage of fossil fuels. The aim of this research study was to develop a novel …

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D. Sep 2014

Shock Pulse Filtering Evaluation On Package Size And Cost, Matthew P. Daum Ph.D.

Journal of Applied Packaging Research

Distribution packaging design often relies on cushion curves to determine required material thickness needed for product protection during shipment. The material thickness chosen based on cushion curves establishes overall package size, a key determiner of logistics costs. Cushion curves are constructed by dropping a mass onto a cushion, and interpreting the resulting shock pulse deceleration. The reported deceleration can be highly influenced by applying a “filter” to the shock pulse, a useful standar d prac - tice that removes unwanted high frequency elements superimposed on top of the basic shock pulse shape. Standard test methods for generating cushion curves generally …

Agricultural Industry Advanced Vehicle Technology: Benchmark Study For Reduction In Petroleum Use, Roger M. Hoy, Rodney Rohrer, Adam Liska, Joe D. Luck, Loren Isom, Deepak R. Keshwani

Adam Liska Papers

Diesel use on farms in the United States has remained relatively constant since 1985, decreasing slightly in 2009, which may be attributed to price increases and the economic recession. During this time, the United States’ harvested area also has remained relatively constant at roughly 300 million acres. In 2010, farm diesel use was 5.4% of the total United States diesel use. Crops accounting for an estimated 65% of United States farm diesel use include corn, soybean, wheat, hay, and alfalfa, respectively, based on harvested crop area and a recent analysis of estimated fuel use by crop. Diesel use in these …

Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth Phd. Aug 2014

Optimization Of Acid Production In Food Waste Via Anaerobic Respiration, Charles Daniels, Raymond Red Corn, Abigail S. Engelberth Phd.

The Summer Undergraduate Research Fellowship (SURF) Symposium

According to the Food and Agriculture Organization of the United Nations, one third of all food produced in world is wasted; 1.63 * 109 metric tons of nutrition is lost to transportation, contamination, or neglect every year (FAO 2013). This wasted food, however, could be repurposed as a substrate for microbial conversion into useful chemicals. This research is aimed at finding the optimal conditions for bacterial colonies to generate volatile fatty acids (VFAs): resources that are used as solvents, medicines, and chemical intermediates usually generated from petroleum based resources (Drumright et al., 2000) (Roscher 2000) (Kolt et al., 2007). …

Portable Pneumatic Demonstrator For Stem Education, Joe Chege, Tyler Helmus, John Lumkes

The Summer Undergraduate Research Fellowship (SURF) Symposium

This project involves the development of a compact and portable pneumatic demonstrator. Using two pneumatic actuators and four solenoid valves, we are able to move an arm on both the X and Y-axes; one actuator for each range of motion. The setup also employs an air pump and a tank to maintain pressure for the actuators. On the actuators there is an arm that holds a camera, a stepper motor and an electromagnet. The stepper motor raises and lowers the electromagnet which is used to pick up objects. The camera is used to automatically identify objects for when the demonstrator …


Quantitative Data Extraction Using Spatial Fourier Transform In Inversion Shear Interferometer, Yanzeng Li Aug 2014

Quantitative Data Extraction Using Spatial Fourier Transform In Inversion Shear Interferometer, Yanzeng Li

Graduate Theses - Physics and Optical Engineering

Currently there are many interferometers used for testing wavefront, measuring the quality of optical elements, and detecting refractive index changes in a certain medium. Each interferometer has been constructed for a specific objective. Inversion shear interferometer is one of them. Compared to other interferometers, it has its own advantages, such as only being sensitive to coma aberration, but it has some limitations as well. It does not allow use of phase shifting technique. A novel inversion shear interferometer was invented using holographic lenses. By using the spatial carrier method, phase information of the wavefront was extracted. The breakthrough of the …

Technology, Science, And Environtmental Impact Of A Novel Cu-Ag Core-Shell Solderless Interconnect System, Milea Joy Kammer

Open Access Dissertations

Tin-based solder is ubiquitous in microelectronics manufacturing and plays a critical role in electronic packaging and attachment. While manufacturers of consumer electronics have made the transition to the use of lead-free solder, there are still a variety of reliability issues associated with these lead-free alternatives, particularly for high performance, high reliability applications. Because of these performance short-comings, researchers are still searching for a material, an alloy, or a unique alternative that can meet the thermal, mechanical, and electrical requirements for conventional reflow solder applications. In an effort to produce a more reliable alternative, Kim et al. proposed the low-temperature (200°C) …
