The Effects Of A User Interface On Productivity The Whiteboard Lms, Jeremiah Jackson, Dr. Barry Mark Lunt Sep 2013

The Effects Of A User Interface On Productivity The Whiteboard Lms, Jeremiah Jackson, Dr. Barry Mark Lunt

Journal of Undergraduate Research

Common among modern universities, BYU included, is usage of Learning Management Systems, commonly known as LMS. LMS are electronic classrooms, often online, that allow for the learning process to continue outside of the traditional classroom setting. For several years, BYU has strived to use the Blackboard LMS to enhance the student experience. Unfortunately, many students and teachers dislike the program, and only use it sparingly, if at all. Initial interviews with students and teachers revealed that the problem behind Blackboard was that it has a poor user interface. Without proper training and/or experience using it, the features of Blackboard can …

Thermal Management Of Lithium Iron-Phosphate Batteries, Nicholas V. Riedel, Perry Carter Sep 2013

Thermal Management Of Lithium Iron-Phosphate Batteries, Nicholas V. Riedel, Perry Carter

Journal of Undergraduate Research

The BYU Electric Vehicle Competition Team (EVCT) elected to use Lithium-iron phosphate batteries as the power source for their streamlined electric race car. This car will be used to attempt a land speed record for electric vehicles under 1800 lbs at the Bonneville Salt Flats in August 2008. These batteries were chosen because they were light-weight and relatively durable. However, there was some concern about using them in place of a more durable battery, like lead acid, because of the extreme temperatures and high electrical loads which the batteries would experience during a run.

A Model Worth A Thousand Pictures, Tyson Triplett, Paul Skaggs Sep 2013

A Model Worth A Thousand Pictures, Tyson Triplett, Paul Skaggs

Journal of Undergraduate Research

Model-making is an essential part of the Industrial Design profession. An idea, no matter how good, is only as valuable as you are able to present it to others. Model-making can be seen as a language by which we share and validate our ideas as designers. More than that, it is a universal language that everyone understands no matter origin, education, or level of understanding. For this reason, we spend more time learning to convince others of our concepts than generating those ideas. A common saying around the department is: “If a picture is worth a thousand words then a …

A Model For Transforming Engineering Education Through Group Learning, Shannon Chance, Gavin Duffy, Brian Bowe, Mike Murphy, Tony Duggan Sep 2013

A Model For Transforming Engineering Education Through Group Learning, Shannon Chance, Gavin Duffy, Brian Bowe, Mike Murphy, Tony Duggan

Conference papers

Electrical engineering educators at Technological University Dublin (DIT) have successfully implemented pedagogical change. They now use group-based, student-centered and inquiry-driven approaches to teach emerging engineers. The objective of this was to foster students’ personal as well as professional skills (i.e., teamwork, communication, self-directed learning, etc.). This paper explores how such change was achieved and provides graphic models that draw from prior phenomenological studies and incorporates aspects of Rogers’ (1962) product adoption curve and Lowe’s (2012) interpretations of it.

Family Tree Mapper: Designing A User Interface For Online Mapping Of Genealogical Data, Craig Fryer, Richard Helps Aug 2013

Family Tree Mapper: Designing A User Interface For Online Mapping Of Genealogical Data, Craig Fryer, Richard Helps

Journal of Undergraduate Research

Designing and Implementing a web service for promoting genealogy and family history work requires a complex process of working with potential end users, designing a product that meets their needs, and testing it with the end users. I found that the greatest challenge to this process was including the end users in every step of the process. Developers tend to make assumptions regarding what is best for the users. These assumptions are often proven wrong when presented to the end user of the product. To circumvent this error, I used the following process.

Plastics For Designers, Colburn L. Jones Aug 2013

Plastics For Designers, Colburn L. Jones

Journal of Undergraduate Research

Plastics for Designers is a basic survey of the industry of plastics specifically written to address the questions and needs of the industrial designer. It is interesting that most people understand and are much more familiar with materials such as wood, metal, glass, stone, etc., than they are with plastics. This is quite amazing when we consider how much we surround ourselves with the very substance of which we are so ignorant. For the industrial designer this unfamiliarity with plastics is an especially vulnerable position as the number of products specifying the use of plastic grows exponentially. It is therefore …

The Size Range Of Bubbles That Produce Ash During Explosive Volcanic Eruptions, Kimberly Genareau, Gopal K. Mulukutla, Alexander A. Proussevitch, Adam J. Durant, William I. Rose, Dork L. Sahagian

Department of Geological and Mining Engineering and Sciences Publications

Volcanic eruptions can produce ash particles with a range of sizes and morphologies. Here we morphologically distinguish two textural types: Simple (generally smaller) ash particles, where the observable surface displays a single measureable bubble because there is at most one vesicle imprint preserved on each facet of the particle; and complex ash particles, which display multiple vesicle imprints on their surfaces for measurement and may contain complete, unfragmented vesicles in their interiors. Digital elevation models from stereo-scanning electron microscopic images of complex ash particles from the 14 October 1974 sub-Plinian eruption of Volcán Fuego, Guatemala and the 18 May 1980 …

Thermal Protection For Extreme Labor, Christopher Hanks, Dave Morgan Aug 2013

Thermal Protection For Extreme Labor, Christopher Hanks, Dave Morgan

Journal of Undergraduate Research

Many people died when temperatures rose to 115°F in Southeastern Europe in July of 2000(Blumberg). The Sahara Desert exceeds 120°F, creating a nearly inhospitable environment. The temperature off of the Phoenix Airport runway was reported at 150°F the summer of 2009. This very same environment is the workplace of ramp agents who lift and load heavy luggage into passenger in, and day out. Through researching methods of heat transfer, and interviewing workers, I have conceptualized a number of cooling solutions which will protect workers from the heat.

Investigation Of Sound Transmission Through An Open Window Into A Room, Caleb F. Sieck Aug 2013

Investigation Of Sound Transmission Through An Open Window Into A Room, Caleb F. Sieck

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

In recent decades, noise levels in cities and the associated annoyance and health consequences have become regular topics of discussion. As a result, the assessment of environmental noise transmitting into buildings has received much attention. Current models of sound transmission through open windows have either neglected their thickness or the presence of a room behind on one side. The objectives of the present work were to (1) develop an accurate analytical model of sound transmission through an open window of finite thickness into a room, (2) verify the analytical model using a finite element model and experimental measurements, and (3) …

The Role Of Personality And Team-Based Product Dissection On Fixation Effects, Christine A. Toh, Scarlett R. Miller, Gül E. Okudan Kremer Jul 2013

The Role Of Personality And Team-Based Product Dissection On Fixation Effects, Christine A. Toh, Scarlett R. Miller, Gül E. Okudan Kremer

Interdisciplinary Informatics Faculty Publications

D esign fixation has been found to be complex in its definition and expression, but it plays an important role in design idea generation. Identifying the factors that influence fixation is crucial in understanding how to enhance the design process and reduce the negative effects of fixation. One way to potentially mitigate fixation is through product dissection activities since this activity has been shown to increase creativity and design space exploration in engineering design. However, product dissection has not been studied in the context of design fixation, so it is unclear if, or how, this type of activity influences fixation. …

Industry Based Multimedia Education, Cameron Wilson, Dr. Geoffrey Wright Jun 2013

Industry Based Multimedia Education, Cameron Wilson, Dr. Geoffrey Wright

Journal of Undergraduate Research

My goal was to study how the cinematographic industry teaches multimedia and digital production, and compare that with how Utah schools teach multimedia and digital production. The outcome was somewhat of a surprise to me. I thought that public school teachers, having proper pedagogical training, and all having graduated from college would be able to provide the students with an adequate learning environment. I found this to be wrong. The students at the Industry based schools overall were much more prepared to go out in the world and be successful in the industry of multimedia. The findings are backed by …

Modular Containerized Provisional Habitations For Emergency Disaster Relief, Matthew Butler, Brian Capt Jun 2013

Modular Containerized Provisional Habitations For Emergency Disaster Relief, Matthew Butler, Brian Capt

Journal of Undergraduate Research

Perhaps the greatest challenge to this project was determining which materials to use in the construction of the modules. There are a multitude of materials that could have been used for the project, many of which might have worked well for the designated use. The shelters have a specific set of criteria that required several different properties that the material had to fill, including: (a) price—it needed to be fairly inexpensive to purchase and ship to a shipping container assembly area, (b) durability—the panels that make up the module must be made from a material that can support itself, the …
