The Legal Status Of Strikers And Replacement Workers, Chun-Shu Su

Theses

On labor-management dispute, each party to the negotiation seeks to protect its economic interests by extracting concession from the other. Both union and management back up their demands with the threat of pressure tactics which would inflict economic harm upon the other party. If the negotiations reach an impasse, a labor union's most powerful weapon at the bargaining table is the credible threat of a strike, a protected right under the National Labor Relations Act. On the other hand, the management may use lockouts or hire new employees to replace those striking workers to force concessions.

Hiring permanent replacements has …

At the conclusion of the paper is an Organized Method Approach to MAP network design and installation that could serve as a …

Effective Disciplinary Process In Management, Ying-Lung Teng

Theses

The application of discipline is the punitive behavior by the employer to suppress the employee's undesired behavior in the work place. However, there are many considerations have to be concerned when applied discipline.

An organization has to support the supervisor when applying discipline because it gives the supervisor the great power in dealing with problem workers. Organizational policy has to specify the degree of discipline and timing of discipline in order to make the supervisor and the employee have an idea about discipline.

The employee becomes satisfied with supervision when the supervisor uses good leadership skills to manage. In order …

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 …

A Proposed Model For Comparing The Performance Of Neural Networks And Statistical Approaches In Predicting Project Profits Of An Asphalt Paving Company, Josephine Giaimo

Theses

It is currently assumed that the performance of a model for predicting project profits of an asphalt paving company varies with an unknown number of parameters. An earlier study indicates that the parameters are not well understood (Berry, 1990). A search of the literature suggests that the available models usually are described by those who develop and use them as universally reliable and valid tools for solving complex problem (Allman, 1989; Bumke, 1988; Clark, 1988; Cohen & Howe, 1988; Fillon, 1989; Kling, 1990; Lawrence, Petterson, & Hartzberg, 1990; Marose, 1990; Pollak, 1988; Reynolds, 1988; Sullivan & Reeve, 1988; Thurber, 1988). …

How Affirmative Is Affirmative?, Shu-Fen Hsu

Theses

Since January 1989, the US Supreme Court has launched a major offensive on affirmative action and civil rights law. The biggest target of the attack is Title VII of the 1964 Civil Rights Act, which bars employment discrimination. As a result, access to private and public contracts for all but the largest black businesses will virtually be nonexistent. For black means decreasing employment and mobility opportunities in the workplace. In addition, complainants will have a more difficult time bringing forth and winning discrimination suits. Racial tension now has a stronger - although subtler - presence in the US. The ascent …

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.

These computer design stations require proper training to be used cost effectively. Consequently, training …

Collage And Installations: Between The Sky And The Earth, Misun Hong

Theses

My work comes from my feelings about abortion. It is a difficult situation for all involved. It is a painful decision for a woman to make, one which not only affects her life but also that of a fetus and other people close to her. I wanted to inform others about the chaotic and complicated sadness that abortion brings to one experiencing it. A woman may ask, "Why do I have to make this decision? I have always tried to be a good person. Why me? Why woman? Why not men? Who's fault is this? I feel trapped, but in …

American Dreams, Mark Lyons

Theses

The intention of this thesis is to investigate metaphorical narratives about experiences in American life. The commentaries depict cultural ironies and satirical imagery of everyday activity. The vessel is used as a stage for these metaphors. I used various glazes, stains, and atmospheres in firing, multiple techniques in construction, and a collection of common historical and personal imagery in each piece. A narrative environment appeared to be the best mechanism to convey statements in the vessels. This body of work reflects many of the experiences I had as a child. These experiences translate into many of the values our society …

Analysis Of Umberger's Theory For Subtractive Color Reproduction, Paul R. Bartel

Theses

A method, proposed by Umberger, for the identification of additive stimuli representative of the red, green, and blue primaries controlled by dyes obeying Beer's law was examined. The primary stability study suggests that for a set of colors created of various dye concentrations, the pattern of Umberger's primary distribution is a translation of the original colors on a chromaticity diagram. Results of a theoretical color reproduction study where the colormatching functions of Umberger's primaries were assumed as the color reproduction system's spectral sensitivities indicate an increase in metric chroma of reproduced colors. Color reproduction errors for a large number of …

The Dynamics Of Bicycling : An Analytical And Experimental Investigation To Determine The Principles Of Design, Sylvester Yen

Theses

Bicycles have existed in working order for a century. They are mechanical products whose dynamic characteristics are highly nonlinear. This has to some extent prevented detailed analysis and for the most part design has been made from practical experience. The advent of computers has markedly changed the techniques and procedures used to calculate the performance of a bicycle. Bicycling began long ago, and since the first bicycle was demonstrated, bicyclists, scientists and engineers have designed thousands of different bicycles considering safety, comfort to ride and ease of control. Nonetheless, nobody claims to fully understand bicycling. If the fundamental principles exist, …

Photo-Induced Electrochemical Etching Of Inp Semiconductor In A Thin Film Cell, Bungsu Iskandar

Theses

The Photo-Induced Electrochemical Etching of n-InP wafer in aqueous solution is investigated for both reservoir and capillary systems. A sinusoidal spatial variation of light intensity pattern is directly illuminated and promoting etching on an InP semiconductor wafer. The etching process is time-efficient, and produces highly isotropical and a promising high resolution pattern. It gives a good reproducibility and has less contaminating features. Its features may be explained by a non-linear relationship between the electrolyte concentration and the photo-generated holes density at the interaction surface. An optimal reaction rate is determined by the ratio of the reactivity to ionic diffusion, either …

Aggression And Symbols Of Power, Karen Kuhn

Theses

Weapons are one of the oldest and most significant forms of artifacts, occurring in virtually all human cultures. Weapons and their technology often determine power structures, not only by brute force of arms, but by long standing respect to ritual aggression. In many cultures, weapons have become abstracted and formalized to become symbols of power and authority, as in a ruler 's scepter, which is a glorified war club. Jewelry functions in much the same manner, proclaiming the social status of the wearer, although in the western world, we have lost most of the symbolic meaning of our jewelry; for …

International Technology Transfer : America Via China, Lijie Dong

Theses

Momentous changes continue to occur in China. The high priorities now accorded economic modernization and improved global relations present a sharp contrast to the years of the Cultural Revolution and earlier. But what happened last year, the June 4 Tiananmen Square massacre, brought about great confusion and uncertainty over China's future course. China may be a constructive trading and strategic partner, or it may choose a more divergent path. U.S. decisions on technology transfer will be an important determinant of which path is followed and the implications for the world.

Landmark-Based Partial Shape Recognition By A Two-Stage Bam Neural Network, Xianjun Liu

Theses

In this thesis, we develop a Bitfirectional Associative Memory (BAM) based neural network to achieve partial shape recognition. To recognize objects which are partially occluded, we represent each object by a set of landmarks. The landmarks of an object are points of interest relative to the object that have important shape attributes. To achieve recognition, feature values (landmark values) of each model object are trained and stored in the network. Each memory cell is trained to store landmark values of a model object for all possible positions. Given a scene which may consist of several objects, landmarks in the scene …

Characteristic Shape Recognition With Fuzzy Dustering, Kalpesh J. Patel

Theses

The problem of shape detection has been treated as one of clustering. A fuzzy-shell clustering(FSC) has been formulated as non linear least squares with fuzzy memberships as weights. An improved FSC algorithm has been proposed based on this formulation to partition the input feature vectors into hyper-spheres. To illustrate the usefulness of improved FSC we have provided numerous examples in 2-D space. The idea has been extended to fuzzy ellipsoidal-shell clustering (rESC). A FESC algorithm has been proposed to partition the input feature vectors into ellipsoidal patterns. To substantiate our claims regarding usefulness of this algorithm we have provided many …

Emergency Preparedness : Disaster Planning For Health Facilities, Narendra R. Patel

Theses

There seems little that can be done to eradicate or even control natural disasters, considering the current state-of-the-art. If nothing can be done to prevent them, we must be prepared to cope with them whenever they do occur.

One possibility for greater assurance that hospital will properly accomplish its post disaster mission is an up-to-date, well-thought-out " Hospital Emergency Preparedness Plan." A well written and rehearsed disaster plan is essential for the proper and timely care of casualties arising from an internal or external disaster.

This thesis attempts to bring together many widely dispersed studies, disaster experiences and principles that …

Microengineered Silicon Beam Switch For Fiber Optics, Hsu-Nien Yang

Theses

A novel microelectromechanical actuator has been designed for moving an optical input fiber into alignment with one of three stationary output fibers. This switching device thus can connect an input optical port to one of 3 selected optical ports. The actuation force is created by a vertical-drive armature measuring 0.5x2.7 mm² mechanically tethered to the input optical fiber. A force of 2.33 mN is obtained from the linear acturator when the vertical stator armature gap is one micron and the applied three phase voltage is 140 Volts. The required force is a function of the input fiber length, e.g. …

The complete process for separating Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Polypropylene (PP), Polystyrene (PS), Polyurethane (PU), and Polyethylene Terephthalate (PET) from a mixture of postconsumer plastics materials was presented. The driving forces considered to achieve separation were different densities and selective solubility of plastics in specific solvents.

The proposed process separates Polyurethane and Polystyrene by using aqueous solutions of different densities. On the other hand, the other five plastics are separated using solvents.

Diagrams showing streams and plastics separation in each unit were discussed. Individual material balances for each step were performed for a …

Max/Min : A Novel Rank Order Based Filter Family, Raafat E. Kamel

Theses

In the early development of signal and image processing, linear filters were the primary tools. Their mathematical simplicity made them easy to design and implement. They also offered satisfactory performance in many applications. However, they show poor performance in other cases, such as image processing.

Nonlinear filtering offered a solution to these problems. Nonlinear filtering has undergone a lot development for a long time. Among the first known nonlinear filters was the median filter, which was proposed by Tukey. Median filter preserves signal or image details better compared to a linear filter. Later other nonlinear filters were developed, including median …

A better approach to meet this requirement is to have a distributed system linked all together with a high capacity LAN using an efficient integration method.

This thesis begins by studying the characteristic feature and suitability of Queued Packet & Synchronous Exchange (QPSX) network architecture. The network models are simulated for QPSX, Ethernet and Token Bus networks for …

Ligament Reconstruction : A Biomechanical Cadaveric Test Of Autogenous Repairs And The In Vivo Evaluation Of Synthetic Scaffold Materials, Anne Marie Daly

Theses

The knee joint is the largest and one of the most complex joints in the human body. The anterior cruciate ligament (ACL) is one of the major intra-articular ligaments responsible for controlling and guiding the knee through most of its range of motion and its rupture alters normal joint mechanics.

One objective of this thesis was to determine if two autogenous tissue ACL reconstruction methods were biomechanically equivalent. The first method using the central one-third of the patellar tendon has been used clinically since the early 1960s. The second method utilizes portions of both the semitendinosus and the iliotibial band. …
