Redesigning The Walker: A More Durable & Dignified Device, Gianna M. Curcio

Honors Capstone Projects - All

Aging and Rehabilitation Engineering is a prominent field with ample room for development of and improvement upon existing options. Surveying city sidewalks, family gatherings, hospital waiting rooms it becomes apparent that the need for mobility aids is abundant. My proposal for Capstone is to redesign the walker from both my mechanical engineering and sculptural perspectives. A walker is meant to improve the quality of life for those who are unable to walk unassisted, but should not come at the cost of the user’s dignity. The way we carry ourselves says a lot about us (i.e. character, will, and level of …

Process Capability In A Computer Integrated Manufacturing Cell, Andrew Austin

Masters Theses & Specialist Projects

With the rise of automation in traditional manufacturing processes, more companies are beginning to integrate computer integrated manufacturing (CIM) cells on their production floors. Through CIM cell integration, companies have the ability to reduce process time and increase production. One of the problems created with CIM cell automation is caused by the dependency the sequential steps have on one another. Dependency created by the previous step increases the probability that a process error could occur due to previous variation. One way to eliminate this dependency is through the use of an in-process measuring device such as a Renishaw spindle probe …

Paint Book System Development, Dale Boynton

Undergraduate Research Symposium

Jarraff Industries has a current Paint Book System which is out of date. The current system is simply pictures of the parts and part numbers for them. It has old versions of parts in it. This creates confusion when the current parts show up and look different. Also, new pictures have to be taken every time a new part is made, which creates a delay in the process to update the books. For a solution three different samples for new Paint Books were made to distribute to users and get feedback on what they liked and did not like about …

Simulation Of An Intake Manifold Pre-Heater For Cold Diesel Engine Startup, Patrick K. Kreun

Masters Theses

Ensuring consistent, reliable diesel engine startups in cold temperatures is of utmost importance in a number of applications. Under extreme temperatures, the use of glow plugs is complemented by intake manifold heaters. In these, the energy released from combustion increases the intake air temperature before the air enters the main combustion chamber. Since the process also alters the stoichiometry of the fuel-air mixture at the intake ports, the preheater operation must be optimized in order to guarantee successful and reliable in-cylinder combustion during engine startups. This paper describes the development of an intake manifold model incorporating an air pre-heater for …

A Control-Chart Based Method For Solder Joint Crack Detection - Conference Proceeding, Jianbiao Pan

Industrial and Manufacturing Engineering

Many researchers have used different failure criteria in the published solder joint reliability studies. Since the reported time-to-failure would be different if different failure criteria were used, it would be difficult to compare the reported reliability life of solder joints from one study to another. The purpose of this study is to evaluate the effect of failure criteria on the reported thermal fatigue life and find out which failure criterion can detect failure sooner. First, the application of the control-chart based method in a thermal cycling reliability study is described. The reported time-to-failure data were then compared based on four …
