Accurate passive acoustic (ASW) performance modeling requires high-fidelity environmental inputs, accurate acoustic propagation and noise modeling as well as the integration of the statistics of the detection of quiet signals in a dynamic environment. In this paper we present the combination of Parabolic Equation modeling with state of the art statistical signal processing to be able to incorpo...

The web has experienced phenomenal growth and has become an important element of the information infrastructure of many organizations. Web performance and around-the-clock availability are the major concerns of Webmasters of sites that support mission critical applications, such as electronic commerce. Web sites are complex computer systems consisting of many interconnected computers, networks,...

Performance measurement and analysis is crucial for steering the organization to realizing its strategic and operational goals. Relevant performance indicators and their relationships to goals and activities need to be determined and analyzed. Current organization modeling approaches do not reflect this in an adequate way. This paper attempts to fill the gap by presenting a framework for modeli...

Performance evaluation and analysis are of key importance to obtain deep understanding of cognitive radio networks. Some effects have been made to model and analyze the performance of cognitive radio networks. In the literature, there are two methodologies: queuing theory/Markov chain-based analysis and stochastic network calculus-based analysis. These two methodologies rely on different mathem...

In recent years, with the improvement of computer processing power and the development of sophisticated visualisation software, the traditional static views of geological maps, cross-sections, and other analogue representations have been replaced by digital, three dimensional (3D) models. Building these 3D models involves the assembly of many previously isolated and disparate datasets into a si...

Crucial to the t ransformat ion of computers into intel l igent mul t imed ia systems is the abi l i ty to access, manipulate and manage visual informat ion . In part icular , video data is becoming a prevalent source of such in format ion. Our Multiple Perspective Interactive Video (MPIVideo), project integrates a variety of visual comput ing operations w i t h model ing and interact ion techn...

Trust is a broad and multidimensional concept that has been widely studied in many disciplines, such as psychology, sociology, and management. In addition to interpersonal relations trust also plays a significant role when technology acceptance is concerned. Information technology (IT) is not an exception but there is a growing interest for understanding the mechanisms of trust formation as wel...

Perfectionism is a personality characteristic that has been found to predict sports performance in athletes. To date, however, research has exclusively examined this relationship at an individual level (i.e., athletes’ perfectionism predicting their personal performance). The current study extends this research to team sports by examining whether, when manifested at team level, perfectionism pr...

The capability to store data about business processes execution in so-called Event Logs has brought to the diffusion of tools for the analysis of process executions and for the assessment of the goodness of a process model. Nonetheless, these tools are often very rigid in dealing with with Event Logs that include incomplete information about the process execution. Thus, while the ability of han...

The field of service innovation strategy has been criticized for its lack of a solid theoretical foundation. To address this issue, we investigate a configuration approach with the prevailing universalistic or contingency perspectives in exploring the effects of service innovation strategies on firm performance. Based on a service-oriented view, we begin by identifying three service innovation ...
