Achieving Ultrafine Grains In Mg Az31b-O Alloy By Cryogenic Friction Stir Processing And Machining, Anwaruddin Mohammed 2011 University of Kentucky

Achieving Ultrafine Grains In Mg Az31b-O Alloy By Cryogenic Friction Stir Processing And Machining, Anwaruddin Mohammed

Theses and Dissertations--Manufacturing Systems Engineering

This thesis presents results from the application of cryogenic cooling on multiple-pass friction stir processing and the subsequent orthogonal machining on friction stir processed and as-received Mg AZ31B-O disks, and shows their combined effects on microstructure and microhardness values. A simple friction stir tool, a specially designed fixture and liquid nitrogen are used to perform multiple-pass friction stir processing experiments on Mg AZ31B-O alloy. The friction stir processed and as-received sheets are then made into disks for the orthogonal machining experiments. This study analyzes the microhardness, microstructure changes by cryogenic friction stir processing and the effect of machining conditions such ...

Evaluating The Impact Of Patient Arrival Patterns In The Performance Of Appointment Scheduling Rules, Alcides Santander-Mercado, Jose Zayas-Castro, Laila Cure, Ali Yalcin 2010 University of South Florida

Evaluating The Impact Of Patient Arrival Patterns In The Performance Of Appointment Scheduling Rules, Alcides Santander-Mercado, Jose Zayas-Castro, Laila Cure, Ali Yalcin

Laila Cure

This paper evaluates the ability of commonly used Appointment Scheduling Rules (ASRs) in smoothing the effect of environmental factors in the performance of an outpatient scheduling system. ASRs have been widely implemented in outpatient clinics to improve performance measures such as staff idle time, patient waiting time, and facility congestion. However, the successful implementation of an ASR depends on its ability in dealing with the environmental factors affecting the system. Factors such as no-shows, variability of consultation times, patient unpunctuality, walk-in patient arrivals and the number of admitted patients per session affect the performance of the clinics in terms of ...

The Best Selection Of Strategic Plans In Balanced Scorecard Using Multi-Objective Decision Making Model, J Dodangeh 2010 Selected Works

The Best Selection Of Strategic Plans In Balanced Scorecard Using Multi-Objective Decision Making Model, J Dodangeh

Jay Daniel

In an increasingly competitive business environment, many organizations have adopted the strategic planning approach in an attempt to achieve excellence in business. Implementation of appropriate strategies plays an important role for organizations' success. Balanced scorecard is an appropriate tool used for designing operational strategies. However, one of the balanced scorecard problems is its selection in strategic plans' performance. In this paper, a model was established for the selection of strategic plans in “balanced scorecard” using “goal programming model” which is one of the multi objective decision making models. So, using the consensus of organizations’ managers and experts' opinions, the measures ...

An Improved Ant Colony System For A Real Time Routing Strategy, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati, Napsiah Ismail 2010 Mazandaran University of Science and Technology, Department of Industrial Engineering

An Improved Ant Colony System For A Real Time Routing Strategy, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati, Napsiah Ismail

Hannaneh Rashidi-Bajgan

There is a large number of literatures about routing and dispatching plans for automated guided vehicle system (AGVS), however a small fraction of these works dealt with dynamic characteristic of this kind of scheduling problems. Current paper surveys a real time strategy to responding requests for supposed material handling system in the plant. We arranged this designing on a preplanned system where all data are known before the constructing routes. An improved ant colony optimization (ACO) is applied in order to find the shortest route path as new solicitations happened. We explore ACO initially for static version of the problem ...


On The Comparative Analysis Of Locomotory Systems With Vertical Travel, G. C. Haynes, Daniel E. Koditschek 2010 University of Pennsylvania

On The Comparative Analysis Of Locomotory Systems With Vertical Travel, G. C. Haynes, Daniel E. Koditschek

Departmental Papers (ESE)

This paper revisits the concept of specific resistance, a dimensionless measure of locomotive efficiency often used to compare the transport cost of vehicles (Gabrielli & von Karman 1950), and extends its use to the vertical domain. As specific resistance is designed for comparing horizontal locomotion, we introduce a compensation term in order to offset the gravitational potential gained or lost during locomotion. We observe that this modification requires an additional, experimentally fitted model estimating the efficiency at which a system is able to transfer energy to and from gravitational potential. This paper introduces a family of such models, thus introducing methods ...

Characterization Of Dynamic Behaviors In A Hexapod Robot, Haldun Komsuoglu, Anirudha Majumdar, Yasemin Aydin, Daniel E. Koditschek

Departmental Papers (ESE)

This paper investigates the relationship between energetic effi- ciency and the dynamical structure of a legged robot’s gait. We present an experimental data set collected from an untethered dynamic hexapod, EduBot [1] (a RHex-class [2] machine), operating in four distinct manually selected gaits. We study the robot’s single tripod stance dynamics of the robot which are identified by a purely jointspace-driven estimation method introduced in this paper. Our results establish a strong relationship between energetic efficiency (simultaneous reduction in power consumption and in- crease in speed) and the dynamical structure of an alternating tripod gait as measured by ...

Industrial and Manufacturing Systems Engineering Technical Reports and White Papers

In 2008, the Department of Defense (DoD) and Department of Energy (DOE) defined a joint initiative to address military energy use by identifying specific actions to reduce energy demand and increase use of renewable energy on DoD installations. A Task Force comprised of representatives from the Office of the Secretary of Defense (OSD), the four military Services, DOE’s Federal Energy Management Program (FEMP), and the National Renewable Energy Laboratory (NREL) was established. In light of DoD priorities, early attention was given to the possibility of net zero energy military installations (NZEI), that is, installations that would meet their energy ...


Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, Sergio Ricardo Pereira Perillo 2010 University of Tennessee - Knoxville

Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, Sergio Ricardo Pereira Perillo

Doctoral Dissertations

This dissertation focused on the IRIS design since this will likely be one of the designs of choice for future deployment in the U.S and developing countries. With a net 335 MWe output IRIS novel design falls in the “medium” size category and it is a potential candidate for the so called modular reactors, which may be appropriate for base load electricity generation, especially in regions with smaller electricity grids, but especially well suited for more specialized non-electrical energy applications such as district heating and process steam for desalination. The first objective of this dissertation is to evaluate and ...

Closing The Gap Between The Industry And Higher Education Institutions- Case Examples From East African Region, Deogratias Harorimana Mr 2010 The University of the South Pacific

Closing The Gap Between The Industry And Higher Education Institutions- Case Examples From East African Region, Deogratias Harorimana Mr

Dr Deogratias Harorimana

Much complained about is the quality of graduates Universities put on the labour market. Less talked about however is why knowledge institutions seems to be bad knowledge managers. In this presentation I argue that DIRECT collaborative relationship between Industry,Governments and Higher Education Institutions is a per-requisite.Good relationship is key to building such a successful knowledge transfer strategies between Industries and Educational and Research Institutions. This paper explores what makes a good Knowledge Transfer Partnership Strategy and highlights some key lessons for businesses, Universities and Government bodies. This paper was a Key note presentation to the Annual International Conference ...
