Cubesat Adcs Validation And Testing Apparatus, Jacob Stevens

Honors Theses

The WALI team at Western Michigan University requested a test environment to validate their CubeSat’s de-tumbling control system and hardware. The test environment required a Helmholtz cage and spherical air bearing. The Helmholtz cage provides an adjustable magnetic field to simulate low earth orbit; the spherical air bearing simulates the friction free environment the CubeSat will experience in space. In conjunction, the two components create an adjustable system that simulates a satellite in low earth orbit.

I-94 Advanced Bridge Replacement, Saleem Alsharari

Honors Theses

The Michigan Department of Transportation has always felt the need of improving and increasing the capacity of the most critical highway in the state of Michigan, I-94. Part of the improvement plan is to increase the capacity of a 6-mile segment along a corridor of I-94 from French Avenue to Trumbull Avenue which is in a suburban neighborhood of Detroit. There are eight bridges built in the 1950’s that need to be re-constructed for a capacity increase. Vehicular and non-motorized traffic must be accounted for in the design of these bridges. The project is intended to increase the service life …

Total Bridge Replacement Of M-13 Over Cheboyganing Creek, Daniel Burns

Honors Theses

The Michigan Department of Transportation sought a proposal consisting of design and construction engineering services for the total bridge replacement of M-13 over Cheboyganing Creek. The M-13 Bridge Project is located on M-13 over Cheboyganing Creek on the Saginaw River in Portsmouth Township, Bay County, Michigan.

Several components of the existing bridge have been rated in poor or serious condition on the National Bridge Inventory rating scale. A total bridge replacement is required and aligns with MDOT strategies to address critical infrastructure needs in the state as well as the Bay Region's five-year plan for managing bridge and culvert infrastructure. …

Extended Gamut Printing In Flexographic Packaging And The Impact Of Brand Management, Andrew Bogan

Honors Theses

Flexography is the dominant print process in regards to the reproduction of packaging products. Packaging, particular the color and graphics, is an essential tangible element for brand owners striving for brand management. Extended gamut printing is a printing technique that can produce high color saturations on packaging samples, which can have positive implications for brand management. Currently, most information on extended gamut printing is proprietary, making it very difficult for non-print industry members to obtain and utilize information relating to the benefits of extended gamut printing. The aim of this study was to provide evidence that packaging samples with extended …

The Comparison Of Effectiveness Between Print Media & Electronic Media In Terms Of Promotion And Recruitment, Katherine Dayton

Honors Theses

This research project’s objective was to determine whether print media such as brochures and booklets are more or less effective than electronic media such as e-mails and webpage advertisements in attracting consumers. A special interest was taken in higher education recruitment and the research was completed by advertising to high school students who are in the process of choosing a school for their higher education experience. The research featured an advertising campaign launched through both print and electronic platforms, directing the consumers to an online survey they were able to take to provide feedback about the experience. This project led …

Least Cost Analysis For Solar Photovoltaic Maintenance Of The Wmu Miller Auditorium Array, Kelsey Pitschel

Honors Theses

The solar photovoltaic array at Miller Auditorium is a 50 kW DC system that has relied on five seasonal angle adjustments and no cleaning measures to reach an average of 64.7 MWh annual energy generation since 2012 1 . This amount of energy generation yields $7,046 in annual energy savings based on current market pricing for end use electricity of $0.1089/kWh 2 . The current adjustment schedule based on seasonal tilts accounts for an annual costs between $760 and $848, but actual adjustments have historically not taken place according to the existing schedule. The analysis focuses on optimizing net energy …

Solar Tracking And Lighting Design For A Multimedia Sculpture, Alexandra Ferguson

Honors Theses

A lighting system utilizing solar energy was built to illuminate a wireframe multimedia sculpture. Increased power generation from the solar cells was achieved using a solar tracking mechanism. Color-selectable light emitting diodes were used to provide the user with unlimited customization options. A digital control system was designed using an Arduino® microcontroller to configure the color of the lights and the positioning of the solar panel. The sculpture will create a sense of community and sustainability among students at the school.

Modeling Product Cooling For Baked And Snack Crackers, Jenna Hagenloch

Honors Theses

The cooling of snack crackers, after the baking process is an important step prior to packaging. A model was developed for cooling the crackers. The model allows for the adjustment of multiple operating conditions, such as temperature, depth of the crackers, and the speed of the line. The completed model provides the user with the ability to predict cooling requirements and to validate pre-existing equipment operating conditions. The model will aid in the design of new equipment as well as modifications to improve existing installations to operate within the desired specifications for each process.

The United States Aviation Industry And The Professional Pilot Training Environment, Andrew Marvin

Honors Theses

This study provides background and analysis of the legislation enacted following the crash of Colgan Air 3407, and the impact that the more stringent qualifications have had on aspiring professional pilots. Participants in the study include professional pilots and aspiring professional pilots, governmental law-making agencies such as the United States (U.S.) Congress and the Federal Aviation Administration (FAA), major and regional airlines, and collegiate flight training programs. The study drew from the National Transportation Safety Board investigation (NTSB) of Colgan Air 3407, federal regulations regarding pilot training and certification standards, and current airline hiring and training programs.

Findings of this …

Human-Assisted Fluid Power Vehicle, Aaron Huntoon

Honors Theses

The rising cost of energy has prompted industrial and technology companies to research and implement renewable or green energy sources in every aspect of their business. This green technology can consist of sources such as: solar, wind, fluid, or others to create energy from renewable sources. The use of these various sources reduces the pollution associated with standard methods of energy development, and it will ultimately drive costs down to benefit the general population. One of the largest benefactors to the use of renewable energy sources is the transportation industry. Billions of people rely on various modes of transportation every …

Designing An Accessible Hall Effect Thruster, Matthew Baird

Honors Theses

A group of three Mechanical Engineering students have selected to design a 200 W Hall Effect Thruster to fulfill the Mechanical and Aeronautical Engineering senior design project. Preliminary studies were performed on the theory behind electric propulsion and plasma physics. The group designed the Western Hall Thruster and used COMSOL Multiphysics® simulation software to refine the magnetic circuit. The group then fabricated and performed magnetic testing of their thruster in Western Michigan University’s Aerospace Laboratory for Plasma Experiments. This testing will seek to prove that a standard research HET can be built by universities without substantial financial resources.

An Analysis Of Preflight Inspection Practices In The Collegiate Training Environment, Seth Laws

Honors Theses

Preflight inspections are a crucial part of flight operations and are required by the Federal Aviation Administration prior to flight. A properly performed preflight by an educated and experienced pilot follows a standard procedure and permits detection of conditions that render an aircraft un-airworthy. A study at Western Michigan University was conducted to determine the effectiveness of this normal procedure in the collegiate training environment. Results indicate the standard procedures for preflight inspections and good supporting habits are in place, but some complacency and a lack of understanding of the standard procedure prevents it from being totally effective among less …
