2014 Evans Student Research Fellowship Program
Through a generous donation from ONU alumnus, Mr. Tom Evans, BSCE ’45, the College of Engineering has established the Evans Student Research Fellowship program, which will provide students in the college the opportunity to work with faculty over the summer on undergraduate research projects. This program will provide funding for 10 weeks of work during the summer at the ONU research rate of $13.36 per hour. Two students will be selected as Evans Fellows to work with faculty on one of two research projects. The two projects are listed below. Please complete the webform at the bottom of this page to apply to become an Evans Fellow.
All applications are due to be submitted by Friday, March 28th.

For the last few years, increases in clock frequency (and hence performance in general) have leveled off for microprocessor chips. The leveling off resulted from those chips reaching their upper limits for operating temperature and power consumption. Although power-aware design can reduce the average power consumption of a processor chip, it does not necessarily reduce the operating temperature and hotspots, which are associated with the high cooling costs. In this project we aim to apply thermal models that use finite-element analysis (FEA) to study the relationship between processor architecture techniques and chip thermal distribution. We then aim to find novel cooling and architecture techniques to reduce hotspots and increase processor performance.
Measuring Characteristics of Recycled Asphalt Pavement Self-Consolidating Concrete
Dr. Ahmed Abdel-Mohti and Dr. Hui Shen
Self-consolidating concrete (SCC) is currently used in many of concrete construction projects. SCC has superior characteristics such as a low yield, considerable viscosity, and does not segregate, which makes it very attractive to contractors. Also, SCC is used when there is no access to vibrators or when it is difficult to vibrate to consolidate the concrete in the event of having heaving and complex reinforcements. SCC can consolidate itself under the effect of its self-weight without the need for mechanical compaction. The aggregates that are used in SCC provide the needed volume, but typically are not made from renewable material. Therefore, the use of waste materials such as Recycled Asphalt Pavement (RAP) to replace a percentage of conventional aggregates can result in a more cost-effective and sustainable concrete solution. The objective of this study is to investigate the fresh and hardened properties of SCC that contains RAP. A large number of concrete mixtures will be developed. A conventional control SCC mixture with targeted properties will be developed and its properties will then be altered to produce the remaining RAP concrete mixtures. The concrete mixtures will have similar properties to the control concrete mixtures, but the percentage of coarse aggregates that will be replaced by RAP will vary. After the fresh and hardened properties and durability of SCC are measured experimentally, a set of recommendations will be presented to assist engineers to determine the suitable percentage by which coarse aggregates can be replaced by RAP.
