How Effective Is The Union Title Vii Grievance Procedures, Yu-Wen Liu

Theses

Title VII forbids certain kinds of discrimination in employment and establishes a federal forum to enforce employee's rights. It means an employer discriminates against any individual in hiring or discharging, because of such individual's race, color, religion, sex, or national origin.

It has been a long time to use Title VII in unlawful practice employment. Therefore, in my thesis, I investigate the development of labor law, special for the development of Title VII of the Civil Right Act of 1964. Secondly, I emphasize on the individual and union that they can effectively make use of their rights under Title VII. …

Optimization On Isdn In Multihop Radio Networks Through Genetic Algorithm, Prashant H. Pahade

Theses

Integrated service of voice and data on a single network has received considerable attention recently. Various techniques have been proposed and analysed for multiplexing voice and data over a large bandwidth channel. Efficient channel allocation for voice and data on multihop radio network is what we are most concerned about. In this paper, we address the problem of determining optimal access policies for a tandem ISDN network by using Genetic Algorithm. Computer Simulation shows that this leads to the decision which is beneficial to the services of both voice and data in the network.

Holographic Photo-Induced Electrochemical Etching Of Diffraction Grating In N-Inp, Pei-Chen Pien

Theses

Maskless laser-induced etching and plating is a novel technology for etching a three dimensional profile on semiconductor wafers. Using this technique, we may avoid the contaminating mask stage and achieve in-situ monitoring of the on-going process. In this thesis, we have presented findings on light diffraction from an etched pattern in a thin-film cell configuration. We suggest that the etched pattern develops mostly linearly in time with this arrangement, although indirect monitoring of the reaction process such as by light diffraction, should be carefully interpreted. In-situ light diffraction monitoring appear as if light was scattered from an etched pattern developed …

Experimental Study On Filterability Of Leukocytes, Qi Wang

Theses

The filterability of leukocytes treated with A23187, Cytochalasin B, PAF and FMLP and pumped through 5 µm polycarbonate filters at a constant flow rate was examined. The concentration of the four agents was systematically varied. The filtration pressure was continuously recorded for data analysis. The pressure-time curves generally showed multiphasic components, following a small jump step at the beginning of the filtration process. The pressure rise was initially fast (initial faster increased phase, IP) and then rose more slowly (later slower increased phase, LP). The leukocytes treated with A23187 showed increased IP and higher LP values; those which were treated …

Electron Field Emission Through A Very Thin Oxide Layer, Guang Yang

Theses

Field Emission of an emitter covered with a very thin oxide layer is modeled and calculated numerically. The additional barrier due to the oxide layer is included in the tunnelling problem by using the standard WKB method and tunnelling transmission matrix method. The following physical parameters are considered: the oxide barrier height, the oxide conduction band edge electron effective mass, and the oxide dielectric constant. Compared with the Fowler-Nordheim equation, which was derived for a clean metallic emitter, the calculation of this work shows a reduction of the emission current density from an emitter covered with an oxide layer a …

Simulation Study Of Monolithic 8-12 Micron Gaas/Algaas Multiple Quantum Well Infrared Image Sensor, Ye Zhu

Theses

The design of a monolithic 8-12 micron GaAs/AlGaAs multiple quantum well infrared image sensor has been tested by computer simulation using PISCES-IIB and SPICE3B.1 software packages. The device structure is in the form of a monolithic GaAs/AlGaAs multiple quantum well (MQW) photoconductor integrated with a GaAs MESFET readout circuit. The readout MESFET's are located in the top layer of the MQW so that a relatively standard GaAs MESFET design and processing technology can be used. The theoretical feasibility of such a vertically integrated structure and the processing compatibility of GaAs/AlGaAs MQW and GaAs MESFET's were investigated in this work.

A Transistor Delay Model Based On Charge Conservation, Bharatsingh K. Bisen

Theses

Delay information of a circuit is often used in the areas of timing verification, timing analysis, race detection and circuit optimization. Given a circuit its delay can be estimated by various simulation techniques. SPICE is one of the simulation techniques, but it is seen that with the increase in the complexity of the circuit the SPICE circuit simulation technique to obtain delay information become cumbersome and computationally too expensive. So as to overcome the above disadvantages of the circuit simulation technique to obtain delay information various timing delay models were developed. However general survey of most of these timing delay …
