PURPOSE To explore the benefit of using 4D multimodal visualization and interaction techniques for defined radiotherapy planning tasks over a treatment planning system used in clinical routine (C-TPS) without dedicated 4D visualization. METHODS We developed a 4D visualization system (4D-VS) with dedicated rendering and fusion of 4D multimodal imaging data based on a list of requirements devel...

Defining a location parameter as a generalization of the median, a robust test is proposed for (a) the nonparametric Behrens-Fisher problem, where the underlying distributions may have different scales and could be skewed, and (b) the generalized Behrens-Fisher problem, where the distributions may even have different shapes. We propose to bootstrap a signed rank statistic based on differences o...

This paper introduces a new point estimation algorithm, with particular focus on coherent noise suppression, given several measurements of the device under test where it is assumed that 1) the noise is first-order stationery and 2) the device under test is linear and time-invariant. The algorithm exploits the robustness of the Pitman estimator of the Cauchy location parameter through the initia...

The structure of modern cities is characterized by the uneven spatial distribution people and activities. Contrary to economic theory, it neither evenly distributed nor entirely monocentric. observed reality result various feedbacks in context interactions attraction repulsion. Heretofore, there no agreement concerning means measuring dimensions these interactions, framework for explaining them...

This paper proposes a parallel approach for the Vector Quantization (VQ) problem in image processing. VQ deals with codebook generation from the input training data set and replacement of any arbitrary data with the nearest codevector. Most of the efforts in VQ have been directed towards designing parallel search algorithms for the codebook, and little has hitherto been done in evolving a paral...

The performance of listening tests can be a laborious process and requires significant preparation and control to ensure good data quality . This is particularly true for sm all impairment listening tes ts perform ed in accordance to recommendation ITU-R BS.1116-1 [ 1] in dedicated listening rooms under calibrated conditions. The us age of s uch central location testing (CLT) methods is time co...
