Selection Of Temperature Measuring Sensors Using The Analytic Hierarchy Process, Shadi Mohammad Al-B'Ool

Systems Science and Industrial Engineering Faculty Scholarship

This study presents an analytic hierarchy process (AHP) method to objectively select the best temperature sensor from among different alternative sensors in a certain industrial application. The underlying decision method based on AHP methodology, ranks temperature sensors with different features with a score resulting from the synthesis of relative preferences of each alternative with respect to the others at different levels considering independent evaluation criteria and sub-criteria. At each level, relative preferences of each candidate alternative with respect to the upper immediate level are calculated from pair-wise comparisons among the candidate alternative sensors with respect to a selected application. Pair-wise …

Innovative Sources Of Non-Aviation Revenue At Small, Non-Hub Airports, Brandon D. Frisbie

MPA Capstone Projects 2006 - 2015

The Greater Binghamton Airport (BGM) in Maine, New York is owned by Broome County and operated under the authority of the Broome County Department of Aviation. The purpose of this capstone project is to identify innovative sources of non-aviation revenue that are viable at small, non-hub airports, like BGM. The Departments of Aviation would like to increase non-aviation revenue at BGM in order to achieve lower station costs for airlines and to preserve the airport's self-sustainability capability.

Running Head: Analysis Of The Just In Time Inventory System At Uhs Wilson Medical Center, Kyle P. Roeber

MPA Capstone Projects 2006 - 2015

In November 2007, United Health Services Materials Management implemented a Just in Time Inventory system to have a tighter control of their supply chain. This project examines the accuracy of the par levels currently employed by the United Health Services and the financial impact of operating a Just in Time inventory system using inaccurate inventory and par levels. In addition, the project researches other hospitals using JIT inventory management systems to compare implementation and management practices of JIT process.

A Large-Stroke Electrostatic Micro-Actuator, Shahrzad Towfighian, Abdulrahman Seleim, Eihab Abdel-Rahman, Glenn Heppler

Mechanical Engineering Faculty Scholarship

Voltage-driven parallel-plate electrostatic actuators suffer from an operation range limit of 30% of the electrostatic gap; this has restrained their application in microelectromechanical systems. In this paper, the travel range of an electrostatic actuator made of a micro-cantilever beam above a fixed electrode is extended quasi-statically to 90% of the capacitor gap by introducing a voltage regulator (controller) circuit designed for low-frequency actuation. The voltage regulator reduces the actuator input voltage, and therefore the electrostatic force, as the beam approaches the fixed electrode so that balance is maintained between the mechanical restoring force and the electrostatic force. The low-frequency actuator …

Testing And Characterization Of Second-Order Differential Microphones, Joshua H. Merlis

Graduate Dissertations and Theses

The focus of this thesis is the testing and characterizing of directional microphones, designed based on the ear of the fly Ormia ochracea. The response of these microphones is modeled as a linear combination of the gradients of the sound field. A least squares approach is employed in order to determine the transfer functions between the response and these gradients. Knowledge of these complex transfer functions is crucial in understanding the nature and quality of the response of these microphones.

Once determined, these transfer functions are used to simulate the plane wave response of differential microphones. This process is invaluable …
