The Decline Of Unionism With A Legal Analysis Of The Individual Rights Of Union Members, Maria-Isabel Cubides De Gast

Theses

The American labor movement has been losing power and membership for the last few years. Historical development and several facts have affected American unionism in such a manner that nowadays less than 20% of the labor force belongs to unions.

Among the most important causes of such decline discussed herein, are the following: lack of social role of unions, failure to satisfy new workers' needs, political reality under this Administration, high unemployment rate, and lack of union democracy.

Lack of union democracy is believed to be the most damaging factor for unionism's decline. Therefore it is studied in more detail, …

Deconvolution Techniques With Applications In Cardiovascular Systems Analysis, Lakshminarayan Rajaram

Theses

System characterization by means of Impulse and Frequency Response Functions are well known in classical linear systems analysis. Impulse Response Function is a time domain description of a linear system where as the Frequency Response Function represents the frequency domain counterpart. Linear systems are often characterized in frequency domain. In many biological research applications, it becomes necessary to examine the impulse response function in order to understand the behavior of the system under investigation. One such application is the arterial system in cardiovascular dynamics. It has been shown that although both representations are identical, some aspects of the arterial system …

Dispersion In The Laminar Flow Of Ellis Model Fluids Through Straight Tubes, Yeong-Hua Huang

Theses

Taylor-Aris dispersion theory is extended to the laminar tube flow of Carreau model fluids and Ellis model fluids and the results are compared with those of power law fluids. It is found that Carreau and Ellis models are more appropriate than power-law model, especially at low pressure gradient.

An exact solution to the unsteady convective diffusion equation in fully developed laminar flow in tube is obtained by applying the generalized dispersion theory of Gill and Sankarasubramanian for Ellis model. The results are compared with those obtained by Booras and Krantz for power-law model. The most interesting result of this work …

A Closed Form Image Force Function For Deposition Of Particles In A Cylindrical Tube, Hsi-Chung Chiou

Theses

This study investigated the behavior of charged particles suspended in a laminar steady incompressible flow in a cylindrical tube under the influences of image , inertia , viscous and gravitational forces. A new expression for the image force was obtained by introducing an approximate potential energy function. The velocity profiles employed in the analysis were uniform and parabolic.

The governing equations derived were based on Newton's second law of motion and were solved by a Runge-Kutta numerical method. The results were obtained for different values of Q, a dimensionless inertia-charge parameter. For a value of Q equal to zero the …

Sensitivity Analysis Of Linear Goal Programming On Priority Level Reordering, Fu-Chia Hor

Theses

The purpose of this research is to study on the sensitivity analysis of priority level reordering of a goal programming model. Two approaches are presented in this study to handle this priority level reordering analysis. The first one is an algorithm to generate the solution of a similar problem with different priority level ordering of the original one utilizing the final solution tableau of the original problem. In doing so, calculation steps and time are saved tremendously.

The second approach is based on the fact that some goal programming problem of different priority level ordering has the same solution as …

An Analysis Of Minimum Shift Keying From The Viewpoints Of Quadrature Multiplexed And Multi-H Continuous Phase Modulation Signaling, Alfred Anthony De Seta

Theses

Minimum Shift Keying (MSK) is a bandwidth efficient modulation scheme which offers superior performance over Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK). This paper discusses these modulation techniques from a quadrature multiplexed signaling viewpoint and compares them in terms of error performance, bandwidth properties and bandlimiting and hardlimiting effects. MSK is also considered as a special case of a multi-h Continuous Phase Modulation (CPM) signal and the Viterbi algorithm is presented as an optimal detection scheme for this class of signals. A computer simulation is performed with the VA as the detection mechanism for an …

Analysis Of Compliant Pins Subjected To Plastic Deformation, Lincoln Miller

Theses

An experimental/numerical analysis of two types of compliant pins is presented: dynamic retention pins and cantilever pins. It is shown that there is a trade-off between the performances of both types of pins. For the same range of retention force, the cantilever pin, with a smaller stiffness, is more forgiving and gives a broader range of deflection. The dynamic retention pin is shown to be more reliable with time and replacement frequency, since it exhibits less plastic deformation for the same range of retention force.

Leading The Electronics Industry Into Total Automation, George P. Rossi

Theses

The introduction of an automated PCB facility in today's technological society still includes a people-oriented facility. The main thrust should be to develop Artificial Intelligence, then the incorporation of LANS, CAD, ICAM, and CIM.

The ability to lace all the functions together is by far the biggest obstacle. The hardware of the equipment is not so much the obstacle to the chemical process and knowledge as the software. Software, which is the capability to talk from the computer to the equipment, is the greatest stumbling block because there is no standardization in the language format.

The method which a computer …

Identification Of Material Constants Of Human Bone Using Finite Element Method For Micropolar Elasticity, Sajid Mannan Sayed

Theses

Bone differs from most engineering materials in the composition of its structure. The classical theory of elasticity fails to correctly predict the stress concentration effects in bones with precracked or notched surfaces, and can be applied only to those materials which exhibit more homogeneity and isotropicity than bone. Therefore, generalized continuum theories, which have addditional degrees of freedom, must be used to determine the stress concentration effects in human bone, especially in regions of high strain gradient, such as a hole or an interface.

In this thesis, efforts have been made to identify the material constants of human bone since …
