Authors: Harikishan Mandalapu , Sandeep Karanamsetty College: Blekinge Institute of Technology The present report is about the parameter analysis of creep models of Nanocomposites (Isotactic polypropylene and CaCo3).The parametric analysis of the nanocomposites under creep was carried out, and the parameters related to creep model are determined by comparing to the experimental results. The ... Full story

Authors:Woytiuk, Kurt College: Luleå University of Technology The paper summarizes an investigzation into methods for treating sugar cane trash in preparation for combustion in a spreader stoker boiler designed for bagasse and supplementary fuel oil. Due to the herbaceaous nature of sugar cane trash, water leaching was proposed and investigated as a means of reducing ... Full story

Authors: Fowler, Gregory Thomas College: University of Maryland Multi-shot molding is rapidly becoming a viable manufacturing process alternative to traditional injection molding with assembly operations due to potential benefits in both cost and quality of the end products. With these new manufacturing processes comes a need to develop new tools for analyzing products at the conceptual design level ... Full story

Authors: Peng, Tao College: University of Maryland Many industrial applications require accurate and rapid measurement of the 3-D shapes of physical objects. Representative applications of 3-D shape measurement include mechanical reverse engineering, 3-D digital replication, and part inspection. Traditional 3-D measurement techniques, such as coordinate measurement machines (CMM) and laser scanning, provide high accuracy but are ... Full story

Authors: Kleyner, Andre V. College: University of Maryland This work develops a new methodology to minimize the life cycle cost of a product using the decision variables controlled by a reliability/quality professional during a product development process. This methodology incorporates all product dependability-related activities into a comprehensive probabilistic cost model that enables minimization of the product’s life ... Full story

Authors:Tsarev, Alexander Sergeevich College: University of Maryland The U.S. Navy has an interest in researching the movement of obstacles in shallow water due to an explosive detonation. Obstacles that are placed in shallow water on a shoreline can damage vehicles that are attempting to land on shore. The U.S. Navy believes that explosives can be used to clear ... Full story

Authors: Elkouss, Paul College: University of Maryland Kinematic modeling has been shown to be important for the understanding and control of co-rotating twin screw extruders. The residence time distribution (RTD) is often used to characterize the steady-state behavior of an extrusion process. Due to the complex rheological behavior of polymer flow in the extruder, few have felt that ... Full story

Authors: Beratlis, Nikolaos George College: University of Maryland In the present work a numerical study of transitional pulsatile flow through planar and cylindrical constrictions is presented. First, a simulation carefully coordinated with an experiment is carried out for validation purposes and results are in good agreement with the experiment. The parametric space that we adopted is similar to ... Full story

Authors: Pines, Michael Louis College: University of Maryland The need exists to fabricate graded metal-ceramic composite armor specimens consisting of nickel and alumina through powder processing techniques and pressureless sintering for dynamic mechanical characterization. An approach is employed to control the thermal shrinkage of each microstructure during sintering by varying particle sizes of the two powders. Models ... Full story

Authors: McMillin, Timothy Walter College: University of Maryland The challenges and benefits of using a liquid-cooled cold plate to cool a multi-processor circuit board with complex geometry were explored. Two cold plates were designed, fabricated, and tested experimentally. Thermal interface resistance was experimentally discovered and confirmed with numerical simulations. A circuit board simulator was constructed. This simulator ... Full story
