Discharge Headway At Signalized Intersections In Monterrey, Nuevo Leon, Mexico, Luis F. Chapa

Civil Engineering Dissertations - Archive

Driver behavior has been the subject of study for almost 100 years. As a result, driver characteristics have been determined and used in the design of highway elements, both for interrupted and for free flow facilities. Signalized intersections represent the most typical interrupted flow facility, with driver reaction time and aggressiveness playing a key role in signal timing design and also in the assessing of intersection performance. These driver characteristics were first determined in the United States in the late 1940's, identifying an average headway (in seconds) between consecutive vehicles as they react to light change from red to green …

Differences Between Women And Minority Businesses And Nonminority Businesses: A Culture-Based Explanation, Eva Dodd-Walker

Management Dissertations - Archive

As the American workforce is buffeted by industries that are downsizing, requesting pay concessions and relocating production to foreign countries with lower factor costs, politicians and union representatives wave the flag of protectionism and explain the state of affairs in terms of a lack of national competitiveness. Porter (1990) links national competitiveness to the competitiveness of the nation's companies, asserting that this competitiveness is achieved through acts of innovation. According to the Small Business Administration (SBA), small business has become the dominant economic force in the United States again (U.S. SBA, 2000), producing 47 percent of all American sales, 51 …

Investigation Of Breast Tumor Hemodynamics By Near Infrared Spectroscopy: Applications To Cancer Therapy Monitoring, Jae Gwan Kim Dec 2005

Investigation Of Breast Tumor Hemodynamics By Near Infrared Spectroscopy: Applications To Cancer Therapy Monitoring, Jae Gwan Kim

Bioengineering Dissertations - Archive

Hyperoxic gas interventions using carbogen (95% O2 and 5% CO2) or oxygen has been tried to increase the tumor oxygenation since it will enhance the therapeutic effects on the tumors. Others in the laboratory had previously applied near infrared spectroscopy (NIRS) to monitor the changes in tumor blood oxygenation during hyperoxic gas intervention and found that oxyhemoglobin concentration changes (D[HbO2]) during gas intervention can be fitted by a two-exponential equation containing two time constants. Based on the model, they formed a hypothesis that changes in oxygenated hemoglobin concentration result from well perfused and poorly perfused regions of an animal tumor …

Kant On "Why Must I Keep My Promise?", B. Sharon Byrd, Joanchim Hruschka Dec 2005

Kant On "Why Must I Keep My Promise?", B. Sharon Byrd, Joanchim Hruschka

Chicago-Kent Law Review

This Article claims that for Kant a contractual obligation generates a universal right, meaning a right against everyone. Accordingly, a right to performance of a contract is more similar to a right in rem than to a right in personam, and failing to perform a contract is more similar to theft than to moral failure to do as promised. Part I shows that for Kant accepting a promise means taking possession of the promisor's choice to commit an act in the future. Part II explains why it is possible to acquire someone else's choice and how one does so in …

Does Today's International Trade Agreement Bind Tomorrow's Citizen?, Gopal Sreenivasan Dec 2005

Does Today's International Trade Agreement Bind Tomorrow's Citizen?, Gopal Sreenivasan

Chicago-Kent Law Review

Focusing on the example of the General Agreement on Trade in Services (GATS), this Article begins by describing an important analogy between domestic Bills of Rights and enforceable international trade agreements. Both effectively disable the majority in later generations from certain exercises of its domestic legislative power. While there is some kind of democratic presumption against disabling the majority in any generation from exercising domestic legislative power, various argumentative strategies have been employed to defeat this presumption in the domestic constitutional case. This Article reviews these strategies and argues next that they cannot be generalized to the case of international …

Duration And Depth: The Effects Of Leader-Follower Relationship Quality On Observer Ratings Of Leadership Performance, William David Rigdon Dec 2005

Duration And Depth: The Effects Of Leader-Follower Relationship Quality On Observer Ratings Of Leadership Performance, William David Rigdon

Psychology Theses - Archive

Previous research has shown that the duration and depth of the leader-follower relationship influences how followers rate their leaders. However, no studies were found that asked whether this relationship influenced how leader-supervisors rated leaders. This study investigated how the closeness (duration and depth) of the leader-follower relationship affected supervisor ratings. Based on previous research, this study expected to find a negative relationship between leader-follower closeness and supervisor ratings of overall performance, advancement potential and risk of career difficulty. Although the duration of the leader-follower relationship marginally supported this hypothesis, duration and depth together (closeness) did not.

Structural Optimization Using Ansys And Regulated Multiquadric Response Surface Model, Ajaykumar Menon Dec 2005

Structural Optimization Using Ansys And Regulated Multiquadric Response Surface Model, Ajaykumar Menon

Mechanical and Aerospace Engineering Theses - Archive

The high computational expense of large non-linear and complex finite element analysis limits or often prohibits the use of conventional codes in engineering design and multidisciplinary optimization. Consequently alternate methods such as Design of experiments (DOE) and Response surface approximation are commonly used to minimize the computational cost of running such analysis and simulation. The basic approach of such methods is to construct a simplified mathematical approximation of the computationally expensive simulation and analysis code, which is then used in place of the original code to facilitate multidisciplinary optimization, design space exploration, reliability analysis etc. When such codes along with …

Numerical Modeling And Analysis Of Pile Supported Embankments, Krishna Nag Rao Dec 2005

Numerical Modeling And Analysis Of Pile Supported Embankments, Krishna Nag Rao

Civil Engineering Theses - Archive

Very soft clays are often avoided in construction due to their low shear strength and high compressibility. Special construction methods are adopted when embankments are constructed on very soft clay or peat. Design of structures on soft ground, where the structure impose large loads onto the ground raises several concerns on factors like bearing capacity failure, differential settlements, lateral pressures and structural instability. Shallow and deep stabilization of soft ground are most frequently used special construction techniques adopted in geotechnical engineering. Chemical (lime and cement) stabilization has been extensively used in both shallow and deep stabilization in order to improve …
