Visual Representations Of Queried Database Results Using Google's Mapping Technologies, Steven Michael Kilbert

Industrial and Manufacturing Engineering

Database queries have been used in business applications throughout the world to filter out specific information which is often used as a basis for making a decision. Despite the broad use of queries, there are only a limited number of ways to represent results, the most common being a dynaset, or results table. This paper describes the investigation of methods to create more visual representations of results using maps to show queried geospatial data. From these methods, applications were successfully developed to create customized maps in Google Earth and Google Maps based on queried geographical data from Microsoft Access databases. …

We have therefore witnessed the establishment of many M&S organizations in the last two decades especially in the more developed world. Less developed countries are starting to recognize the need for such capability especially that the problems they face are not less complex. In this paper, we present a preliminary study towards a business plan for establishing a scientific center for Modeling, Analysis, Simulation and Animation in Jordan (JoSAMA) and …

Development Of A Framework To Evaluate Human Risk Towards Sustainable Risk Management, Ra'ed M. Jaradat, Rani A. Kady, C. Ariel Pinto

Engineering Management & Systems Engineering Faculty Publications

Risk managers are constantly faced with the challenge of making decisions at various levels of their organizations. One of the challenges, which often times is unavoidable, lies in assigning a monetary value to human risks. Such challenge necessitates engineering managers to make educated decisions on the level of risk that the organizations and businesses should accept when it comes to human. The purpose of this study is to suggest a suitable framework that captures this aspect of engineering Risk Management in order to make rational and sustainable decisions about such assessed risk. This will be accomplished by exploring the tools, …

Development Of A Contingency Capillary Wastewater Management Device, Evan A. Thomas

Mechanical and Materials Engineering Faculty Publications and Presentations

The personal body-attached liquid liquidator (PBALL) is conceived as a passive, capillary-driven, contingency wastewater disposal device. In this contingency scenario, the airflow system on the NASA crew exploration vehicle is assumed to have failed, leaving only passive hardware and vacuum vent to dispose of wastewater. To meet these needs, the PBALL was conceived to rely on capillary action and urine wetting conditions from 0° < θadv ∼ 90°, be adaptable for both male and female use, collect and retain up to 1 L of urine, minimize splash-back, and allow continuous draining of the wastewater to vacuum while minimizing cabin air loss. A subscale PBALL test article, which was tested on NASA's reduced-gravity aircraft in April 2010, successfully demonstrated key components of this design.

Detection Of Explosive Threats By Using Embedded Wireless Sensor Based Networks, Jake Daniel Hertenstein

Masters Theses

"This thesis focuses on the development of novel schemes for the detection of unintended electromagnetic emissions (UEE) from passive radio frequency (RF) receivers and chemical and biological (CB) agents for the purpose of locating explosive threats (ET) to improve survivability for equipment and personnel in the surrounding environment. The methods and architectures used in this work were developed for use with wireless sensor networks (WSNs). While previous work has shown that highly sensitive equipment is capable of long-range detection of UEE the intention of this work is to develop a network of small, low cost smart sensor nodes (SSNs) capable …

Synergy Between Biology And Systems Resilience, Ashik Chandra

Masters Theses

"Resilient systems have the ability to endure and successfully recover from disturbances by identifying problems and mobilizing the available resources to cope with the disturbance. Resiliency lets a system recover from disruptions, variations, and a degradation of expected working conditions. Biological systems are resilient. Immune systems are highly adaptive and scalable, with the ability to cope with multiple data sources, fuse information together, makes decisions, have multiple interacting agents, operate in a distributed manner over a multiple scales, and have a memory structure to facilitate learning. Ecosystems are resilient since they have the capacity to absorb disturbance and are able …

Improving Resiliency Using Graph Based Evolutionary Algorithms, Jayakanth Jayachandran

Masters Theses

"Resiliency is an important characteristic of any system. It signifies the ability of a system to survive and recover from unprecedented disruptions. Various characteristics exist that indicate the level of resiliency in a system. One of these attributes is the adaptability of the system. This adaptability can be enhanced by redundancy present within the system. In the context of system design, redundancy can be achieved by having a diverse set of good designs for that particular system. Evolutionary algorithms are widely used in creating designs for engineering systems, as they perform well on discontinuous and/or high dimensional problems. One method …

Fusion Of Imprecise Qualitative Information, Florentin Smarandache, Xinde Li, Xianzhong Dai, Jean Dezert

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper, we present a new 2-tuple linguistic representation model, i.e. Distribution Function Model (DFM), for combining imprecise qualitative information using fusion rules drawn from Dezert-Smarandache Theory (DSmT) framework. Such new approach allows to preserve the precision and efficiency of the combination of linguistic information in the case of either equidistant or unbalanced label model. Some basic operators on imprecise 2-tuple labels are presented together with their extensions for imprecise 2-tuple labels. We also give simple examples to show how precise and imprecise qualitative information can be combined for reasoning under uncertainty. It is concluded that DSmT can deal …

Project And Risk Management: A Systematic Approach, Baqer Alali, C. Ariel Pinto, Andreas Tolk, Rafael Landaeta

Engineering Management & Systems Engineering Faculty Publications

The main purpose of this paper is to discuss three related topics of project management, systems management, and risk management. The issue that would be addressed in this paper is how risks are addressed in project and systems management, and how risks are propagated between projects and systems. A framework is proposed to overcome the problem of risk propagation from project to the systems. It was shown that the proposed framework can be deployed to existing risk management process with reasonable interventions (e.g. process prescribed by PMI). Finally a proof-of-concept application shows potential of the framework for various types of …

E.J. Gallo Winery Spirit-Makers Facility, Aaron Pickar

Industrial and Manufacturing Engineering

With growing demand for E.J. Gallo spirit brands, the cramped and cluttered facility allocated to the spirit-makers does not provide an adequate work environment to design and test new hard alcohols. E.J. Gallo Winery wants to relocate the spirit-makers to a new facility located near the brandy production floor for under 200,000 dollars. In order to do this, a revised systematic approach to facility design is used.

In this process, the departments are first defined, then the relationships between these departments and the space requirements are documented. Once these planning steps are complete, alternative layouts are constructed and analyzed until …

Implementing Rfid To Improve Animal Shelter Inventory And Allocation, Adam Mach

Industrial and Manufacturing Engineering

The purpose of this project is to observe the best way to incorporate Radio Frequency Identification (RFID) technology into the animal inventory system present in animal shelters, while also observing the benefits of implementing this system. The Woods Humane Society was used in this project as a sample animal care facility that could benefit from this application.

Many RFID systems can be observed in other industries, but very few examples this technology exist in animal shelters or smaller animal care facilities. Part of the reason for that is because funds are scarce at most animal care facilities, like the Woods …
