Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

Impact of RFID Technology on Replenishment Decisions for Multi-Echelon Supply Chains

Creator:: Cavazos Sanchez, Myrna Leticia
Abstract:: Radio frequency identification (RFID) has long been regarded as an automated data collection technology that promises solutions to inefficiencies found in supply chains such as “just-in-case” inventory stock, inventory obsolescence, stockouts, and theft. However, the disappointingly slow return on RFID investment has forced companies to examine and redefine RFID initiatives....

Efficient Algorithms for Solving the Median Problem on Real Road Networks

Creator:: Ghanbartehrani, Saeed
Abstract:: Location theory is a well-established and active research area. The main objective in location theory is to find the best locations for facilities to meet supply and demand constraints and minimize total cost. The median problem (also known as the 1-median problem) is a special case in location analysis that...

Heat treatment effects on CPM-M4 tool steel performance as edged blade material

Creator:: Lian, Sidi
Abstract:: CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...

A framework for assessing and improving the resilience of complex engineered systems during the early design process

Creator:: Mehrpouyan, Hoda
Abstract:: As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of...

An investigation into the electrochemical removal of unwanted residual material protrusions from parts

Creator:: Bingham, Bruce C.
Abstract:: Manuscript I: The removal of residual casting material from gating has traditionally been performed by abrasive grinding techniques. However, high amounts of belt wear can occur when working with high strength alloys, especially those typically seen in the aerospace industry. An alternative machining process called electrochemical machining (ECM) uses electrolysis...

Two-stage flexible flow shop scheduling with blocking constraint and batching machines

Creator:: Panahi, Hadi
Abstract:: In this dissertation, a two stage flexible flow shop scheduling problem is studied, where in stage 1, there are identical batch processors (burnout ovens) and in stage 2, there are identical discrete processors (furnaces). Batch processors perform a pre-heating process on a batch of jobs at a time and discrete...

Modeling and optimization of radio frequency identification networks for inventory management

Creator:: Suriya, Atipong
Abstract:: Stock loss and out-of-stocks are outcomes of poorly designed inventory management systems and can lead to significant revenue losses. Inventory management systems (IMS) based on radio frequency identification (RFID) have the potential to minimize these losses if they are properly designed and deployed. However, the placement of RFID readers to...

Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...
Resource Type:: Masters Thesis

A wireless sensor network approach for estimating individual task time

Creator:: Atichat, Tanawat
Abstract:: Most existing methods for generating individual task time estimates in production systems where jobs move through various manually operated workstations remain tedious and time consuming. For existing systems, average task times may vary considerably from prior estimates causing system inefficiencies, poor scheduling and poor planning decisions. Accurate and up-to-date estimates...
