Experimental Investigation Of Hard And Brittle Materials Machining Using Micro Rotary Ultrasonic Machining, Amey V. Patwardhan

Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

The demand for miniaturized device and components is rapidly increasing in fields of aerospace, energy, optics, electronics and communication, automation and medical. Rotary Ultrasonic Machining (RUM) is capable of machining hard and brittle materials such as advanced ceramics, glass and silicon used in many industries. Rotary Ultrasonic Machining (RUM) is a hybrid machining process in which material is removed by conventional grinding and ultrasonic machining. Micro RUM is a downscaled version of a macro RUM and is similar to micro Ultrasonic Machining (micro USM), where the vibration takes place in work piece instead of tool.

A Software Application For The Selection Of Temperature Measuring Sensors Using The Analytic Hierarchy Process (Ahp), Tarek Al-Hawari, Shadi Mohammad Al-B'Ool, Amer Momani

Systems Science and Industrial Engineering Student Scholarship

This study presents a software application that applies the Analytic Hierarchy Process (AHP) to objectively select the best temperature sensors. Three industrial applications and seven sensor alternatives are considered. The developed application performs the selection process in a computerised, easy–to–use graphical user interface. The underlying decision method ranks temperature sensors with scores resulting from the synthesis of relative preferences of each alternative at different levels considering independent evaluation criteria. Pair–wise relative comparison matrices collected from experts are embedded and are retrieved according to user specifications. A case study is conducted which involves selecting the best sensor for an automotive catalytic …
