This paper presents an effective modeling methodology for Ultra-wideband (UWB) antennas. The methodology is based on augmenting an existing narrow-band model with a macro-model while simultaneously perturbing component values of the narrow-band model. The narrow-band model is an empirical-based circuit and the macro-model described by rational functions is determined using data fitting approach...

A matched case-control design is a common approach used to assess diseaseexposure relationships, and is often a more efficient method than an unmatched design. However, for the valid analysis of such an approach, a modeling technique that incorporates the matched nature of the data is needed. This prohibits the use of a standard unconditional logistic regression analysis generally available in ...

Traditional TCP traffic modeling has focused on “micro-scale” modeling of TCP, i.e., detailed modeling of a single TCP flow. While micro-scale models of TCP are suitable for understanding the precise behavior of individual flows, they are not well suited to the situation when a large number of TCP flows interact with each other as is the case in realistic networks. In this survey, we present se...

Agile Modeling (AM) provides a set of best practices of “lightweight” modeling to support the modeling process on a macro level within the agile development teams. At the core of AM is close collaboration with stakeholders which is similar to participative Enterprise Modeling (EM). Hence, the objective of this paper is to analyze the potential of using EM in agile development projects to addres...

ORGANIZATIONAL CULTURE, MACRO AND MICRO EMPOWERMENT DIMENSIONS, AND JOB SATISFACTION: AN APPLICATION OF CONCURRENT MIXED AND MULTI-LEVEL METHODS IN THE FEDERAL SECTOR Timothy L. Bailey, Ph.D. Touro University International 2009 This dissertation examined the interrelationship of organizational culture; macro (structural) and micro (psychological) empowerment; and job satisfaction. Specifically,...

Although the range expansion and inter-cell interference coordination (ICIC) have been shown to successfully enhance the capacity and load balancing in the heterogeneous network (HetNet), their impacts on the handover performance are not fully understood in existing studies. In this paper, a novel measurement-based approach is adopted to investigate these issues, where the real measured data of...

The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...

This paper introduces the possibilities of multi-agent system application for the modeling and intelligent control in the case of coarse ceramics burning process. It consists of technological description of this process, its decomposition into agents and macro-model of the decision system. Then multi-agent system modeling tools, such as alternating-time temporal logic and alternating transition...

This paper focuses on the development of a novel approach for modeling the behavior of agents in the RoboCup Rescue Agent Simulation Competition. A two layered approach is developed, with a macro-level behavior responsible for the strategic, high level decisions and a micro-level behavior dealing with the local particularities of the competition. The micro-level behavior was implemented using a...
