This experiment is concerned with sampling submicrometer
particles in near sonic and supersonic flows.
The study employed a high volume condensation aerosol
generator to produce stearic acid particles having a
geomet ...
The objective of this research project was to identify the limitations associated
with schedule-based Material Requirements Planning (SBMRP) and to
present a knowledge-based expert system (KBES) approach to solve these ...
The problem of scheduling jobs to minimize total weighted tardiness in flowshops,
with the possibility of evolving into hybrid flowshops in the future, is investigated in
this paper. As this research is guided by a rea ...
In February 1994, EPA proposed to "refine" its carbon monoxide (CO) hot spot model,
CAL3QHC, to increase its accuracy and reliability. Currently, this proposal includes
using hourly meteorological data recorded at airp ...
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 ...

In this research we address a sequence-dependent group scheduling problem on a set of unrelated-parallel machines where the run time of each job differs on different machines. To benefit both producer and customers we at ...
For some decades, the assembly of printed circuit boards (PCB), had been thought to be an ordinary example of mass production systems. However, technological factors and competitive pressures have currently forced PCB ma ...
This thesis investigates a simple dynamic model of the hind leg
of a beetle during initiation of a step. The primary assumption was
that the full load of the body was carried on the hind leg during
this time. That is, ...
A method was sought to predict the flight paths and collisions for closely spaced ink droplets of various sizes as a design aid for ink-jet printing development. Computational fluid dynamics models of two rigid aligned s ...
Automated storage and Retrieval (AS/R) systems have had
a significant impact on storage and retrieval of finished
goods, work-in-process, and raw materials and supplies. A
microcomputer-based simulation model was deve ...
A comparative study of three six-axis force sensors selected after an extensive literature survey is presented. A sensor to measure ground contact force at each foot of a walking machine is recommended.
Principles of fo ...
The sketching software developed in this thesis, is aimed to serve as an
intelligent design tool for the conceptual design stage of the mechanical design
process.
This sketching software, Sketch Pad for Windows, close ...
A calorimeter capable of measuring the heat capacity of 1 mg size samples from
4.2 to greater than 100 K has been designed, constructed, and tested. The sample is
bonded to the end of a 0.002 inch diameter, 0.5 cm long ...
During the operation of phase-change ink-jet printers a bubble formation
phenomenon often occurs. These bubbles are detrimental to the operation of
the printer and substantial efforts are made to remove them. The objec ...
Droplet formation in inkjet cartridges has been studied for several
decades to improve print qualities. Currents and rigid nozzle plates are used
inside the cartridge to fix the size of droplets exiting the chamber. Th ...
Capacitor discharge welding (CDW) is a rapid solidification joining process under
the influence of one-dimensional thermal gradients. Although CDW is useful for joining
small parts and dissimilar metals, CD welded join ...
The properties of polyurethane impregnated Kevlar 29 bed were determined
using Woven Fabric Micromechanics (WFM.) These properties were used to perform a
linear static analysis on loaded coal-beds to compare maximum ve ...
The purpose of this study is to provide the necessary technical
background and data for the development of a suspension system for a
recumbent bicycle. For this reason, the customer requirements-design
criteria for th ...
Literature reports have indicated that application of
sonic pressure waves enhances the rate of impregnation of
preservatives in wood. However, these studies have been
limited and inconclusive. The technique or proces ...
