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), …

Linear regressions were used to determine if the relationship between OPTEMPO and turnover intentions were significant. When accounting for job satisfaction and organizational commitment the relationship between OPTEMPO and turnover intentions is not significant, this indicated that OPTEMPO and turnover …

Intelligence Surveillance And Reconnaissance Asset Assignment For Optimal Mission Effectiveness, Ryan D. Kappedal

Theses and Dissertations

This research develops mathematical programming techniques to solve an intelligence, surveillance, and reconnaissance sensor assignment problem for USSTRATCOM. The problem as specified is hypothesized to be difficult (i.e. np-hard). With the smallest test cases, the true optimal solution is found using simple optimization techniques, but, due to intractability, the optimal solutions for larger test cases are not found using these same techniques. Instead, heuristic techniques are applied to several test cases in order to determine the best, robust methodologies to find true or near optimal solutions. Specifically, simulated annealing (SA) is tested for convergence properties across several different parameter settings. …

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 …

Engineering Microbial Fuels Cells: Recent Patents And New Directions, Justin C. Biffinger, Bradley R. Ringeisen

United States Navy: Publications

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 …

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 …

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 …

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 …

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

United States Army: Publications

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 …

Influence Of Snow And Ice Crystal Formation And Accumulation On Mercury Deposition To The Arctic, Thomas A. Douglas, Matthew Sturm, William R. Simpson, Joel D. Blum, Laura Alvarez-Aviles, Gerald J. Keeler, Donald K. Perovich, Abir Biswas, Kelsey Johnson

United States Army: Publications

Mercury is deposited to the Polar Regions during springtime atmospheric mercury depletion events (AMDEs) but the relationship between snow and ice crystal formation and mercury deposition is not well understood. The objective of this investigation was to determine if mercury concentrations were related to the type and formation of snow and ice crystals. On the basis of almost three hundred analyses of samples collected in the Alaskan Arctic, we suggest that kinetic crystals growing from the vapor phase, including surface hoar, frost flowers, and diamond dust, yield mercury concentrations that are typically 2-10 times higher than that reported for snow …
