Simulation of Rarefied Flows in MEMS Devices by Atomistic and Multiscale Methods
… the overlap, DSMC noise, and the number of DSMC time steps is investigated. Significant computational time savings are demonstrated with the coupled method. The coupling of DSMC with compressible Navier-Stokes equations is also developed. It is shown that by using DSMC/Navier-Stokes coupling, the …

The impact of intelligent transportation systems on supply chain management
… levels is compared to a baseline to yield a % time savings. Next, a sensitivity analysis is performed by introducing a random error term which is normally distributed with mean zero and a specified standard deviation. The author concludes that there appears to be a fairly consistent trend in …

Network design for integrated vehicle-sharing and public transportation service
… stations strongly influence the level of travel time savings achieved by the users of the system. Our goal, then, is to select station locations so as to maximize the connectivity with the public transportation system, increase the accessibility to the urban area, reduce travel times, reduce …

An Evaluation of Personal Computer-Based Aviation Flight Instruction
… There was a significant airplane flight time savings to final certification in the experimental group. In all cases, there was positive correlation between student's and instructor's attitudes towards the use of the PCATD, and it was significant in seven of twenty-two pairings.

Moving from conventional bus service towards bus rapid transit : establishing priorities
… variables of each component was based on the time savings and cost associated with their implementation. Time savings were evaluated from a user standpoint as the total travel time, including access time, waiting time, and in-vehicle time. Time savings for the agency were evaluated through …

Development of a Five-Axis Machining Algorithm in Flat End Mill Roughing
… of a mold requires at least 20-30 weeks of lead time. Of those 20-30 weeks 50% is spent in machining. Of that time 50-65% is spent in rough machining. For a mold or die that amounts to 7 to 8 weeks of rough machining. If one could achieve as much as a 10-15% reduction in machining time that would …

Integration of the Transportation Systems Analysis Model for the Small Aircraft Transportation System
… The integrated model allows for faster running times and quicker analysis of the results. The ability to calculate travel time savings for travelers was also included to the final model. The modeling framework developed is known as the Transportation Systems Analysis Model (TSAM).

Accelerated Quantitative Magnetization Transfer (qMT) Imaging
… use of qMT has been hindered by long acquisition times inherent to z-spectrum-based imaging techniques including qMT and chemical exchange saturation transfer (CEST). This thesis uses sparseSENSE, a combined parallel imaging and compressed sensing technique, to accelerate MT-weighted images. In …

Improving operational efficiency of a semiconductor equipment manufacturing warehouse through strategic allocation of parts
… Unit. At Varian, the target part delivery time from the warehouse to the production floor is 24 hours. However, during busy periods, parts are not delivered on time. Late part delivery from the warehouse to the production floor could delay the machine laydown date, which in turn could …

The technology-evoked time use rebound effect and its impact on consumer behaviour in tourism.
… to be sufficient alone. This is because monetary savings caused by energy efficiency improvements can, rather unexpectedly, lead to increased energy demand, the phenomenon known as the rebound effect (RE). Time savings from time efficiency technologies can similarly intensify energy consumption, …

Power system transient stability analysis of stiff systems using the Multirate method
… are complex and can take a substantial amount of time to simulate. The Multirate integration method is one way to speed up simulation studies. This thesis studies the effects of using a type of Multirate simulation method in a software package. In this study, the Multirate method is used mainly on …

Forests and fisheries in the Brazilian Amazon: Understanding incentives to comply with conservation efforts
… is that smallholder land clearing paths over time are affected by assessments of the probability of being caught violating the Forest Code. I develop a dynamic decision model that considers the potential benefits and costs accrued from land clearing through time by a representative smallholder …
