This paper aims at describing a new framework which allows for the quantitative combination of different edge detectors based on the correspondence between the outcomes of a pre-selected set of operators. This is inspired from the problem that despite the enormous amount of literature on edge detection techniques, there is no single one that performs well in every possible image context. The so...

The use of simulations has become increasingly frequent in the study and the performance evaluation of network systems. The simulation environment deeply influences the behaviour of results, so a model that simulates a realistic movement of the nodes is necessary for the study of wireless networks. Simple mobility models do not provide realistic scenarios. Often movements are completely random,...

The simTD (Safe and Intelligent Mobility: Test Field Germany) research project is another step towards bringing Car-to-X technology to marketability. One of its envisioned applications is a Traffic Information System (TIS) based on selfgenerated maps for vehicles not equipped with digital maps. To assure reliable operation, the function itself, its performance and the effect of its input parame...

Multisensor signal-level image fusion has attracted considerable research attention recently. Whereas it is relatively straightforward to obtain a fused image, e.g. a simple but crude method is to average the input signals, assessing the performance of fusion algorithms is much harder in practice. This is particularly true in widespread “fusion for display” applications where multisensor images...

OBJECTIVE The aim of this study was to determine how strongly the performance of navigation tasks is affected by changing electronic map interfaces and by individual differences in spatial ability. BACKGROUND Electronic map interfaces have two common configurations, north up and track up. Research suggests that north-up maps benefit some navigational tasks and track-up maps benefit others. Ho...

[naeini1] one of the biggest organizational challenges in deployment of strategies is the time lag between the cause-and-effect relations according to a lag between indicators of strategic objectives. with adding the time factor, the strategic objectives at different times have a causal relationship with each other. the causal relationships between strategic objectives are essential. in this pa...

The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbomachines and a combustion system. This tutorial addresses the basic characteristics of each of the components, and defines the rules under which they interact, as well as typical control limits and control concepts. Important nondimensional characteristics such as Mach number and ...

A growing community of researchers applies the concept map for elicitation and representation individual’s knowledge structure especially within knowledge-intensive processes in organizations. As an extension of prior works on concept map, this study aims to explore a new indicator of structural properties of concept map from an information entropy perspective to predict an individual’s problem...

Localization and mapping are essential capabilities of virtually all mobile robots. These topics have been the focus of a great deal of research, but it is not always easy to tell which methods are best. This paper discusses performance evaluation for an important sub-problem of robot mapping, map optimization. We explore aspects underlying the evaluation of map optimization such as the quality...
