Two Tales Of Bundling, Bruce H. Kobayashi

George Mason University School of Law Working Papers Series

The economic literature on bundling has made many theoretical advances. However, several omissions reveal themselves. The advances have largely been on the theoretical side. These models contain restrictive assumptions regarding the existence of monopoly in some markets, and the nature of rivalry in others. The models generally ignore obvious and ubiquitous reasons firms may use bundled discounts. These models have not been subject to robustness checks, nor have their assumptions been tested empirically. As a result, the literature that shows the possibility of anticompetitive harm does not provide a reliable way to gauge whether the potential for harm would outweigh …

Guide To Nebraska’S Wetlands And Their Conservation Needs: Second Edition, 2005, Ted Lagrange

Nebraska Game and Parks Commission: Publications

Wetlands — a source of great interest, and at times conflict. Wetlands represent different things to different people. At times they’re viewed as shallow, muddy nuisances while at other times they’re viewed as wonderful, varied and productive assets. This is because wetlands take on many roles as part of a complex and dynamic system. Understanding wetlands and wetland issues requires understanding the complex and varying roles that wetlands can play. To aid in this understanding, this guide defines wetlands, discusses their importance and dynamics, identifies threats and losses, describes conservation programs, and takes an in-depth look at Nebraska’s regional wetland …

The Relationship Between Student Perceptions Of Parental Involvement And Grade Eight Reading And Math Achievement In A Rural Georgia Middle School, Wayne A. Hickman

Doctoral Dissertations and Projects

The purpose of this study was to examine the relationship between students' perceptions of parental involvement and grade 8 reading and math achievement as measured by the Georgia Criterion Reference Competency Test (CRCT). This study relied on a theoretical framework developed by Epstein (1987). This framework includes a six-part categorization of parent involvement typologies (Type 1—parenting, Type 2—communication, Type 3—volunteering, Type 4—learning at home, Type 5—decision-making, and Type 6—collaborating), which were used as the basis for data collection and analysis. The High School and Family Partnerships: Questionnaires for Teachers, Parents, and Students were developed by Epstein and Salinas (1993) for …

An Artificial Neural Network That Utilizes Hip Joint Actuations To Control Bifurcations And Chaos In A Passive Dynamic Bipedal Walking Model, Max J. Kurz, Nikolaos Stergiou

Journal Articles

Chaos is a central feature of human locomotion and has been suggested to be a window to the control mechanisms of locomotion. In this investigation, we explored how the principles of chaos can be used to control locomotion with a passive dynamic bipedal walking model that has a chaotic gait pattern. Our control scheme was based on the scientific evidence that slight perturbations to the unstable manifolds of points in a chaotic system will promote the transition to new stable behaviors embedded in the rich chaotic attractor. Here we demonstrate that hip joint actuations during the swing phase can provide …

Partial Adjustable Autonomy In Multi-Agent Environment And Its Application To Military Logistics, Hoong Chuin Lau, Lucas Agussurja, Ramesh Thangarajoo

Research Collection School Of Computing and Information Systems

In a rapidly changing environment, the behavior and decision-making power of agents may have to be adaptive with respect to a fluctuating autonomy. In this paper, a centralized fuzzy approach is proposed to sense changes in environmental conditions and translate them to changes in agent autonomy. A distributed coalition formation scheme is then applied to allow agents in the new autonomy to renegotiate to establish schedule consistency. The proposed framework is applied to a real-time logistics control of a military hazardous material storage facility under peace-to-war transition.

Mobile technology extends computing and the Internet into the wireless medium, and provides greater flexibility in communication, collaboration, and information sharing. In this research, we used the ‘Value-Focused Thinking’ approach to examine the strategic implications of mobile technology in a leading publishing company. The result is a means-ends objective network that depicts the fundamental objectives of using mobile technology and how the fundamental objectives can be achieved through means objectives. The research findings suggest three main strategic implications of mobile technology: (1) improve working process; (2) increase internal communication and knowledge sharing; and (3) enhance sales and marketing effectiveness.

Dispatching Continuous Moves, David Ronen

Journal of Transportation Management

Continuous Moves (CM) is a term coined by the trucking industry. This paper defines CM’s, classifies them and discusses their economies. A unifying mathematical optimization model for dispatching orders is then presented. The model selects the best way to dispatch each and every order, whether as a part of a CM or not. However, the model does consider all the feasible types of CM’s. Practical aspects associated with implementing CM’s are also discussed.

Discrete Approximations Of Differential Inclusions In Infinite-Dimensional Spaces, Boris S. Mordukhovich

Mathematics Research Reports

In this paper we study discrete approximations of continuous-time evolution systems governed by differential inclusions with nonconvex compact values in infinite-dimensional spaces. Our crucial result ensures the possibility of a strong Sobolev space approximation of every feasible solution to the continuous-time inclusion by its discrete-time counterparts extended as Euler's "broken lines." This result allows us to establish the value and strong solution convergences of discrete approximations of the Bolza problem for constrained infinite-dimensional differential/evolution inclusions under natural assumptions on the initial data.

Improving Large-Scale Network Traffic Simulation With Multi-Resolution Models, Guanhua Yan

Dartmouth College Ph.D Dissertations

Simulating a large-scale network like the Internet is a challenging undertaking because of the sheer volume of its traffic. Packet-oriented representation provides high-fidelity details but is computationally expensive; fluid-oriented representation offers high simulation efficiency at the price of losing packet-level details. Multi-resolution modeling techniques exploit the advantages of both representations by integrating them in the same simulation framework. This dissertation presents solutions to the problems regarding the efficiency, accuracy, and scalability of the traffic simulation models in this framework. The ``ripple effect'' is a well-known problem inherent in event-driven fluid-oriented traffic simulation, causing explosion of fluid rate changes. Integrating multi-resolution …

Essays in Education

This article provides a brief history of the formation of Temple College in the late 19th century and its official recognition as a university during the early years of the 20th century. The institution evolved from very humble origins of private tutoring sessions in a Baptist pastor’s office. In only a few decades, the institution attracted faculty with reputable academic credentials, offered undergraduate degrees in practical and scholarly fields, and provided graduate and professional education to men and women of the working class, various racial and national heritages, and wealthy families. Despite numerous obstacles, Temple’s founder, Russell Conwell, turned his …

A Prediction Code For The Thrust Performance Of Two-Dimensional, Non-Axisynnetric, Converging Diverging Nozzles, Angela M. Geatz

Theses and Dissertations

The objective of this research is to develop a prediction code for the Air Force Research Laboratory Propulsion Directorate that can accurately determine the gross thrust coefficient for a user defined nonaxisymmetric two-dimensional converging diverging nozzle. The code includes the effects of friction, angularity, and expansion losses on nozzle efficiency. To demonstrate the prediction method, the generated computational results were compared to experimental data, as well as computational results from other existing nozzle performance codes, for a number of different nozzle geometries. The nozzle internal performance prediction code showed excellent agreement with experimental data in predicting the gross thrust performance …

Nonlinear Regression Methods For Estimation, Eric B. Nelson

Theses and Dissertations

Regression techniques are developed for batch estimation and applied to three specific areas, namely, ballistic trajectory launch point estimation, adaptive flight control, and radio-frequency target triangulation. Specifically, linear regression with an intercept is considered in detail. An augmentation formulation is developed. Extensions of theory are applied to nonlinear regression as well. The intercept parameter estimate within the linear regression is used to identify the effects of trim change that are associated with the occurrence of a control surface failure. These estimates are used to adjust the inner loop control gains via a feed-forward command, hence providing an automatic reconfigurable retrim …

Establishment Of A System Operating Characteristic For Autonomous Wide Area Search Vehicles, Brian A. Kish

Theses and Dissertations

The optimal employment of autonomous search and destroy vehicles is addressed. The results apply to air, land, or water vehicles with 1, k, or infinite warheads. The specific scenarios considered involve an air vehicle searching a battle space for stationary targets in the presence of false targets. Encounters are modeled with uniform, Poisson, and normal distributions. Linear and circular search patterns are examined. All relevant parameters are extracted from intelligence information, the sensor performance specification, and the air vehicle performance specification. Analytic system effectiveness measures are derived using applied probability theory. The effectiveness measures derived in this dissertation handle time-varying …

Rate Dependence And Short Term Creep Behavior Of Pmr-15 Neat Resin At 23 And 288°C, Candice M. Westberry

Theses and Dissertations

This research focuses on experimental investigation of rate-dependent behavior and short-term creep of PMR-15 neat resin at 23 and 288°C. Effect of loading rate on monotonic stress-strain behavior was explored in monotonic tests at constant stress rates of 0.75, 0.075, and 0.0075 MPa/s at 23 and 288°C. In addition, effect of prior stress rate on creep behavior was explored in creep tests preceded by uninterrupted loading to a target stress. At each temperature three creep tests were conducted for a given stress level, where loading rate was changed from test to test. Creep stress levels were 30 and 25 MPa …

Investigation Of The Performance Characteristics Of Re-Entry Vehicles, Charles A. Bilbey Jr.

Theses and Dissertations

When a non-US spacecraft reenters the Earth's atmosphere, having the ability to accurately determine its performance characteristics is a primary concern. This study investigated the atmospheric re-entry profiles of a maneuverable re-entry vehicle. The re-entry vehicle was modeled as a point mass with aerodynamic properties. Equations of motion were numerically integrated, giving the time histories of position, velocity and flight path angle. The algorithm is able to generate a complete and feasible entry trajectory of a approximately 25-minute flight time in about 5 to 10 seconds on a desktop computer, given the entry conditions and values of constraint parameters. This …

Liquid Crystal On Silicon Non-Mechanical Steering Of A Laser Vibrometer System, Kevin S. Kuciapinski
