This paper addresses the problem of correcting visual registration errors in video-based augmented reality systems. Accurate visual registration between real and computergenerated objects in combined images is critically important for conveying the perception that both types of object occupy the same 3-dimensional (3D) space. Previous augmented reality systems concentrated on improving 3D coord...

Drug combination is a critically important therapeutic approach for complex diseases such as cancer and HIV due to its potential for efficacy at lower, less toxic doses and the need to move new therapies rapidly into clinical trials. One of the key issues is to identify which combinations are additive, synergistic, or antagonistic. While the value of multidrug combinations has been well recogni...

This study uses an experimental design comparing 235 offenders assigned either to drug treatment court or treatment as usual. It extends prior analyses of this study sample to examine whether differences observed between drug treatment court subjects and control subjects at one and two years after the start of the program persist after three years, when many of the subjects had ceased active tr...

In the Wundtian paradigm, commonly used in visual science and psychophysics, each new observer is treated as a replication. Any conclusions regarding the processing of visual information can be extended to other observers only by indirect inference from successful replication. Differences between individuals require a new theory for each observer, whereas in the neo-Galtonian paradigm, commonly...

In computerized analysis of chest radiographs is the detection of the lung field boundaries. Once the boundaries of the lung fields are identified, physiological measurements of the lung features are possible. The properties of the boundary are determined by edge detection along with suitable filter algorithms. The aim of proposed work is to develop an experimental system which segmented and an...

Although programs convey an unambiguous meaning, the grammars used in practice to describe their syntax are often ambiguous, and completed with disambiguation rules. Whether these rules achieve to the removal of all the ambiguities while preserving the original intended language can be difficult to ensure. We present an experimental ambiguity detection tool for GNU Bison, and illustrate how it ...

We demonstrate experimentally the possibility of efficiently detecting properties of quantum channels and quantum gates. The experimentally realized quantum channel detection method has been recently proposed theoretically, and allows us to characterize the properties of quantum channels with a much smaller experimental effort than quantum process tomography. Here, the optimal detection scheme ...

background: several landmine detection methods, based on nuclear techniques, have been suggested up to now. neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are the nuclear methods used for landmine detection. in this paper an optimized (safe and effective) moderating structure using an 241am-be neutron source for detecting landmines has been invest...
