The purpose of this study is to demonstrate methodology for in-use measurement of dieselelectric passenger railroad locomotives using a Portable Emission Measurement System (PEMS). The methodology was developed and demonstrated based on railyard load tests of three locomotives, including one GP40 and two F59s. These locomotives have mechanically governed prime mover engines ranging from 140 to ...

In-Cylinder Pressure Sensors (ICPS) today are close to satisfying the robustness, performance and cost requirements for application to closed loop control and monitoring of production automotive engines. Using the Robust Design framework as a compass, this thesis first checks the evidence for emergence followed by tracking the evolution of the sensor component itself and its application to robu...

In order to have an experience on movers having a nanometer precision, a mover has been fabricated and its performance is tested. In the ILC, range of about 1mm is required to cure the long term drift of the tunnel floor and precision of some nanometers is required during the beam operation in IR (Interaction Region). To achieve these range and precision, the mover has two stages, coarse mover ...

Something very odd was going on in the corner of my patio. An earthworm apparently hovering an inch above ground. Its wriggling did not, however, seem to be generating any levitational force, so how could it have freed itself from gravity? Closer inspection (with reading glasses now on) revealed that this actually no at all, but something far more interesting, and certainly not flying. Iberian ...

As the neurogenerative epithelium of the vertebrate central nervous system expands during embryonic development, nuclei of neural progenitors undergo a process called interkinetic nuclear migration (IKNM). The nuclear movements of IKNM are generally believed to involve gradual migrations from apical to basal and back during the G1 and G2 phases of the cell cycle, respectively. Yet the kinetics ...

This research investigates early mover advantage of a special group of online firms: entrepreneurial etailers that operate on third party eCommerce platforms. The conventional wisdom suggests that early mover advantage would not be substantial when barrier to entry is low. However, this research argues that etailers, even when barrier to entry is low online, can enjoy early mover advantage beca...
