Effect Of Unitization And Product Types On Readability Of Tagged Packages Of Consumer Goods, Jay A. Singh, R. Holtz, S. P. Singh, K. Saha
Industrial Technology and Packaging
Proper implementation of radio frequency identification (RFID) has the potential to revolutionize supply chain management. This technology provides simultaneous indirect scanning of multiple packages and palletized loads equipped with a RFID tag, transmitting substantially more information than a bar code. Also, stored information on the tag can be updated according to inventory status, thus, eliminating key limitations of barcode technology. This study was designed to address some of the currently known shortcomings of the RFID technology. One of the commonly occurring drawbacks is transmitted signal from RFID antennae is reflected from metal objects or absorbed by water contained in a …

Rfid Research And Testing For Packages Of Apparel, Consumer Goods And Fresh Produce In The Retail Distribution Environment, S. P. Singh, M. Mccartney, Jay Singh, R. Clarke
Industrial Technology and Packaging
Radio frequency identification (RFID) is a term used for any device that can be sensed at a distance by radio frequencies with few problems of obstruction. The origins of the term lie in the invention of tags that reflect or retransmit a radiofrequency signal. According to a recent article by Forrester Research, the minimal ‘Slap and Ship’ approach to RFID compliance will cost an individual company between $2 million and $20 million. Because retailers like Wal-Mart plan to share with their suppliers all the RFID-generated data points (from when a case/pallet enters their distribution centre until it leaves their stockroom), …

Output Feedback Controller For Operation Of Spark Ignition Engines At Lean Conditions Using Neural Networks, Jonathan B. Vance, Brian C. Kaul, Jagannathan Sarangapani, J. A. Drallmeier
Electrical and Computer Engineering Faculty Research & Creative Works
Spark ignition (SI) engines operating at very lean conditions demonstrate significant nonlinear behavior by exhibiting cycle-to-cycle bifurcation of heat release. Past literature suggests that operating an engine under such lean conditions can significantly reduce NO emissions by as much as 30% and improve fuel efficiency by as much as 5%-10%. At lean conditions, the heat release per engine cycle is not close to constant, as it is when these engines operate under stoichiometric conditions where the equivalence ratio is 1.0. A neural network controller employing output feedback has shown ability in simulation to reduce the nonlinear cyclic dispersion observed under …

A Suite Of Robust Controllers For The Manipulation Of Microscale Objects, Qinmin Yang, Jagannathan Sarangapani
A Suite Of Robust Controllers For The Manipulation Of Microscale Objects, Qinmin Yang, Jagannathan Sarangapani
Electrical and Computer Engineering Faculty Research & Creative Works
A suite of novel robust controllers is introduced for the pickup operation of microscale objects in a microelectromechanical system (MEMS). In MEMS, adhesive, surface tension, friction, and van der Waals forces are dominant. Moreover, these forces are typically unknown. The proposed robust controller overcomes the unknown contact dynamics and ensures its performance in the presence of actuator constraints by assuming that the upper bounds on these forces are known. On the other hand, for the robust adaptive critic-based neural network (NN) controller, the unknown dynamic forces are estimated online. It consists of an action NN for compensating the unknown system …

Application Of Design Of Experiments To Flight Test: A Case Study, Aaron A. Tucker, Gregory T. Hutto, Cihan H. Dagli
Engineering Management and Systems Engineering Faculty Research & Creative Works
Modern flight test tends to be a complex, expensive undertaking so any increases in efficiency would result in considerable savings. Design of experiments is a statistical methodology which enables a highly efficient investigation where only the samples needed are collected and analyzed. the application of design of experiments to the design of flight test can result in a significant increase in test efficiency. Increased information is garnered from the data collected while the number of data points required to understand the system is reduced. in this effort, an actual flight test program serves as a case study to compare and …
Engineering Microbial Fuels Cells: Recent Patents And New Directions, Justin C. Biffinger, Bradley R. Ringeisen
Engineering Microbial Fuels Cells: Recent Patents And New Directions, Justin C. Biffinger, Bradley R. Ringeisen
U.S. Navy Research
Fundamental research into how microbes generate electricity within microbial fuel cells (MFCs) has far outweighed the practical application and large scale development of microbial energy harvesting devices. MFCs are considered alternatives to standard commercial polymer electrolyte membrane (PEM) fuel cell technology because the fuel supply does not need to be purified, ambient operating temperatures are maintained with biologically compatible materials, and the biological catalyst is self-regenerating. The generation of electricity during wastewater treatment using MFCs may profoundly affect the approach to anaerobic treatment technologies used in wastewater treatment as a result of developing this energy harvesting technology. However, the materials …

Pseudomonas Aeruginosa Infection Of The Auricular Cartilage Caused By “High Ear Piercing”: A Case Report And Review Of The Literature, Henry H. Rowshan, Karen Keith, Dale Baur, Peter Skidmore
US Army Research
Piercing of various parts of the body has gained tremendous popularity among adolescent and adult populations in recent years. There are no exact statistical reports on the number of body piercings being performed in the United States. One study among 481 college students in New York revealed that 42% of men and 60% of women had body piercing. In the past, the majority of complications of ear piercing were associated with the lobule. Torn ear lobes, localized infection, hypertrophic scars, allergic contact dermatitis, and keloid formations were among the most common, with no significant morbidity. However, “high ear piercing,” defined …

How Do You Interpret A Confidence Interval?, Paul Savory
How Do You Interpret A Confidence Interval?, Paul Savory
Industrial and Management Systems Engineering: Instructional Materials
A confidence interval (CI) is an interval estimate of a population parameter. Instead of estimating the parameter by a single value, a point estimate, an interval likely to cover the parameter is developed. Many student incorrectly interpret the meaning of a confidence interval. This paper offers a quick overview of how to correctly interpret a confidence interval.
Why Divide By (N-1) For Sample Standard Deviation?, Paul Savory
Why Divide By (N-1) For Sample Standard Deviation?, Paul Savory
Industrial and Management Systems Engineering: Instructional Materials
In statistics, the sample standard deviation is a widely used measure of the variability or dispersion of a data set. The standard deviation of a data set is the square root of its variance. In calculating the sample standard deviation, the divisor is the number of samples in the data set minus one (n-1) rather than n. This often confuses students. This paper offers a quick overview of why the divisor is (n-1) for calculating the sample standard deviation.

Faculty of Informatics - Papers (Archive)
This paper examines the underlying logic behind the rules configured in a RFID middleware to support “smart business processes” in one retail supply chain. Through a detailed investigation of the underlying business processes, we will demonstrate how businesses rules can be defined, configured and refined in a RFID middleware. The results confirm that RFID technology is not a “Plug and Play” solution. RFID middleware configuration will require a high level of customization. Finally, this study allows the improvement of our understanding of the real potential of RFID technology in the supply chain context.
Emergence Of Networks In Distance-Constrained Trade, Kumar Venkat, Wayne W. Wakeland
Emergence Of Networks In Distance-Constrained Trade, Kumar Venkat, Wayne W. Wakeland
Systems Science Faculty Publications and Presentations
Long-distance trade has been rapidly increasing in recent years. As traders from around the world exchange goods, they form networks with traders as nodes and transactions as links. We use an agent-based model of a simple artificial economy to examine the emergence of trade networks when the distance between traders matters. Distance can become an issue if fuel for transportation becomes expensive or if greenhouse gas emissions from transportation become a major concern. We model the distance constraint as a transaction cost proportional to the amount of goods traded and the distance that those goods must be transported. We find …
Improved Tabu Search Heuristics For The Dynamic Space Allocation Problem, Alan Mckendall
Improved Tabu Search Heuristics For The Dynamic Space Allocation Problem, Alan Mckendall
Faculty & Staff Scholarship
The dynamic space allocation problem(DSAP) presented in this paper considers the task of assigning items(resources) to locations during a multi-period planning horizon such that the cost of rearranging the items is minimized. Three tabu search heuristics are presented for this problem. The first heuristic is a simple basic tabu search heuristic. The second heuristic adds diversification and intensification strategies to the first, and the third heuristic is a probabilistic tabu search heuristic. To test the performances of the heuristics, a set of test problems from the literature is used in the analysis. The results show that the tabu search heuristics …
Scheduling Maintenance Activities During Planned Outages At Nuclear Power Plants, Alan Mckendall, James Noble, Cerry Klein
Scheduling Maintenance Activities During Planned Outages At Nuclear Power Plants, Alan Mckendall, James Noble, Cerry Klein
Faculty & Staff Scholarship
In order to maintain high production rates, electric power as well as manufacturing plants shut down so that maintenance activities can be performed on machines/equipment. These planned shut downs (outages) usually occur at least once a year and are more frequent for plants with older machines/equipment. The major costs associated with outages are cost of materials, labor cost, and loss of production cost. Due to high cost incurred from loss of production, the objective is to schedule maintenance activities such that outage duration is minimized. Since the resources required to perform maintenance activities are very limited, the problem of scheduling …

Tabu Search Heuristics For The Crane Sequencing Problem, Alan Mckendall
Faculty & Staff Scholarship
Determining the sequence of relocating items (or resources) moved by a crane from existing positions to newly assigned locations during a multiperiod planning horizon is a complex combinatorial optimisation problem, which exists in power plants, shipyards, and warehouses. Therefore, it is essential to develop a good crane route technique to ensure efficient utilisation of the crane as well as to minimize the cost of operating the crane. This problem was defined as the Crane Sequencing Problem (CSP). In this paper, three construction and three improvement algorithms are presented for the CSP. The first improvement heuristic is a simple Tabu Search …

Data was collected from 71 closed projects using a survey composed of closed-ended questions. The data collected was cross tabulated and statistically analyzed using Friedman's test and Spearman's correlation. The results provide evidence of the association of the performance of knowledge transfer across projects with (a) the individual factors of gender and role of key project stakeholders …
The Effects Of Congressional Elections On Future Equity Market Returns, Vincent Louis Ovlia, David Lee Enke, Michael C. Davis
The Effects Of Congressional Elections On Future Equity Market Returns, Vincent Louis Ovlia, David Lee Enke, Michael C. Davis
Engineering Management and Systems Engineering Faculty Research & Creative Works
As the primary entity responsible for new legislation, Congress is capable of enacting legislation that may affect future market returns. To examine potential effects, the percentage of the House of Representatives and Senate controlled by a political party is examined. Additionally, the effect on returns in a change in the percentage of seats gained or lost in Congressional elections is analyzed. To test both theories, a modified “partisan view” model is adopted. Results point to the fact that equity markets perform better in situations in which power is distributed between political parties.

Implementing An Architectural Framework To Define And Deliver Net-Centric Capability To Legacy Military Air Assets Operating Within A System Of Systems, Mark S. Anderson, S. M. Martin, Cihan H. Dagli, Ann K. Miller
Engineering Management and Systems Engineering Faculty Research & Creative Works
The United States Air Force (USAF) is implementing an integrated net-centric system of systems for airborne operations in support of the global war on terror (GWOT). The GWOT demands that a successful architecture framework transforms and delivers net-centric assets to the war-fighter in a timely manner. A critical component of this implementation is the transformation of legacy strategic air platforms into net-centric air power assets operating within a system of systems. The System Architectural (SA) framework, and the Department of Defense Architectural Framework (DoDAF) are ways of managing complexity and organizing information within a system of systems network.

Using Agent Based Simulation And Game Theory Analysis To Study Information Sharing In Organizations – The Infoscape, Richard Donald Jolly, Wayne W. Wakeland
Using Agent Based Simulation And Game Theory Analysis To Study Information Sharing In Organizations – The Infoscape, Richard Donald Jolly, Wayne W. Wakeland
Systems Science Faculty Publications and Presentations
Information sharing in organizations, especially the impact of sharing freely versus not sharing, was studied using game theory and agent based simulation. A game theoretic analysis was performed, and Netlogo simulations were carried out wherein some agents hoarded information while others shared information. As expected, sharing was found to greatly increase the overall amount of information within the organization. Unexpectedly, agents who share acquire more information than hoarders. This is due to the synergy that develops between groups of agents who are sharing with each other. The density of the agents is important-as the density increases, the probability increases that …

Background: Immunization with RTS,S/AS02 consistently protects some vaccinees against malaria infection in experimental challenges and in field trials. A brief immunization schedule against falciparum malaria would be compatible with the Expanded Programme on Immunization, or in combination with other prevention measures, interrupt epidemic malaria or protect individuals upon sudden travel to an endemic area.
Methods: We conducted an open label, Phase 2a trial of two different full dose schedules of RTS,S/AS02 in 40 healthy malaria-naıve adults. Cohort 1 (n = 20) was immunized on a 0, 1, and 3 month schedule and Cohort 2 (n = 20) on a 0, …
Vietnam: Historians At War, Mark Moyar
Vietnam: Historians At War, Mark Moyar
US Army Research
By the early 1990s, when I began studying the Vietnam War, the American public had largely lost interest in the history of that conflict. The Civil War and World War II were the wars that historians were advised to cover if they wanted to reach the public. Among government officials, military officers, and political scientists, Vietnam was considered irrelevant, because the United States would never get caught in protracted counterinsurgency warfare again. Iraq changed all that. Ever since the outbreak of insurgency in the former empire of Saddam Hussein, people of all persuasions have been mining the history of Vietnam …
