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 ...

Targeting Net Zero Energy At Marine Corps Air Station Miramar: Assessment And Recommendations, Samuel Booth, John Barnett, Kari Burman, Joshua Hambrick, Michael S. Helwig, Robert Westby

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 ...


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 2010 University of Pennsylvania

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 ...

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

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 ...

Technical Reports (ESE)

We report on the design and development of X-RHex, a hexapedal robot with a single actuator per leg, intended for real-world mobile applications. X-RHex is an updated version of the RHex platform, designed to offer substantial improvements in power, run-time, payload size, durability, and terrain negotiation, with a smaller physical volume and a comparable footprint and weight. Furthermore, X-RHex is designed to be easier to build and maintain by using a variety of commercial off-the-shelf (COTS) components for a majority of its internals. This document describes the X-RHex architecture and design, with a particular focus on the new ability of ...


Heavy Traffic Analysis Of A Simple Closed-Loop Supply Chain, Arka P. Ghosh, Sarah M. Ryan, Lizhi Wang, Ananda Weerasinghe 2010 Iowa State University

Heavy Traffic Analysis Of A Simple Closed-Loop Supply Chain, Arka P. Ghosh, Sarah M. Ryan, Lizhi Wang, Ananda Weerasinghe

Industrial and Manufacturing Systems Engineering Publications

We consider a closed-loop supply chain where new products are produced to order and returned products are refurbished for reselling. The solution to aprice-setting problem enforces the heavy traffic condition, under which we address the production rate control problem for two types of cost functions. Wesolve a drift-control problem for an approximate system driven by a correlated two-dimensional Brownian motion. The solutions to this system are then used to obtain asymptotically optimal control policies. We also conduct a numerical study to explore the effects of different parameters on the optimal production rates and the resulting costs.


The Effect Of Sinusoidal Rolling Ground Motion On Lifting Biomechanics, Xiaopeng Ning, Gary A. Mirka 2010 Iowa State University

The Effect Of Sinusoidal Rolling Ground Motion On Lifting Biomechanics, Xiaopeng Ning, Gary A. Mirka

Industrial and Manufacturing Systems Engineering Publications

The objective of this study was to quantify the effects of ground surface motion on the biomechanical responses of a person performing a lifting task. A boat motion simulator (BMS) was built to provide a sinusoidal ground motion (simultaneous vertical linear translation and a roll angular displacement) that simulates the deck motion on a small fishing boat. Sixteen participants performed lifting, lowering and static holding tasks under conditions of two levels of mass (5 and 10 kg) and five ground moving conditions. Each ground moving condition was specified by its ground angular displacement and instantaneous vertical acceleration: A): +6°, −0 ...

The Impact Of Employee Trust On The Perceptions Of Organizational Safety And Quality, Gretchen A. Mosher, Nir Keren, Steven A. Freeman 2010 Iowa State University

The Impact Of Employee Trust On The Perceptions Of Organizational Safety And Quality, Gretchen A. Mosher, Nir Keren, Steven A. Freeman

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Human factors play an important, but often overlooked, role in the management of safety and quality in the work environment. One of these factors is the level of trust employees have in their supervisor and the management of the organization. Anecdotal evidence has linked a stronger safety climate with a more robust quality climate as both programs depend on teamoriented employees who can spot potential issues and correct them on the job. An increased understanding of factors influencing employee perceptions of the priority of safety and quality within the organization is an important consideration when planning safety and quality educational ...


Delivery Of An Online Quality Management Course For Adult Learners, Gretchen A. Mosher, Steven A. Freeman 2010 Iowa State University

Delivery Of An Online Quality Management Course For Adult Learners, Gretchen A. Mosher, Steven A. Freeman

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

The introduction of quality management systems in the workplace offers strategies for process improvement, strategic organizational change, and continuous quality improvement. Opportunities to learn these concepts in an online format allows for an efficient and cost effective delivery method. However, adult learners often do not have the comfort level with online learning that college-aged students take for granted. This presentation will describe the process which was used to develop and deliver an online non-credit course in quality management systems for adult students. Strategies used to encourage online discussion and student interaction will also be discussed.


Measurement And Analysis Of Safety And Quality Decision-Making In The Workplace, Gretchen A. Mosher 2010 Iowa State University

Measurement And Analysis Of Safety And Quality Decision-Making In The Workplace, Gretchen A. Mosher

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Human factors play an important, but often overlooked, role in the management of safety and quality in the work environment. One of these factors is trust. Little research has been done to explore the linkages between trust and safety or quality workplace outcomes. Safety and quality programs depend heavily on the decisions employees make on the job, therefore, an increased understanding of factors influencing their decision-making process is an important component of safety and quality educational intervention.
