The illusion of control refers to a phenomenon whereby people believe their chances of success at a task are greater than would be warranted by objective analysis. This article raises two questions. First, how robust is the illusion of control? Second, how might the illusion be 'shattered?' Previous experimental demonstrations involved situations that can be likened to unique or single-shot gam...

INTRODUCTION Single-shot Echo-Planar Imaging (EPI) is the sequence most commonly used for fMRI experiments. At high field, e.g. 7T, magnetic field inhomogeneities cause spins to become out of phase quickly, and distortion and signal dropout become severe [1]. Consequently, single-shot EPI fMRI suffers technical limitations at high field. Here we consider two alternatives to EPI for high field f...

Shot peening applies a residual compressive stress field (RCSF) on the surface of parts. It also shifts “crack nucleation sites” to sub-surface locations. A nondestructive method of measuring the stresses, Sin2ψ was utilized here and the stress values introduced to Ansys software. For this purpose, uniform stress in all directions was applied on the con rod. Loading on the rod in Ansys had thre...

In a previous research project [5], we found there are several disadvantages of the current Linux scheduler. So we employed a alternative scheduler, Resource-Based Earliest Deadline First scheduler(RB-EDF), to solve these problems. Though RB-EDF performs better than the Linux scheduler in handling soft realtime processes, it can not enforce resource usages smaller than 1 tick(10ms) using the re...

We report on tests of an x-ray beam size monitor based on coded aperture imaging[1]. This technique uses a mask pattern to modulate incoming photons, with the resulting image being deconvolved through the mask and detector responses, including the effects of diffraction and attenuation materials in the path, over the spectral and angular distribution of the synchrotron radiation generated by th...

In th i s paper we present a novel improvement to existing schemes for a b r u p t shot change detection. Existing schemes declare a shot change whenever t h e f rame to f rame histogram difference (FFD) value is above a particular threshold. In such a n approach, a high value for t h e threshold results in a small number of false a larms a n d a large number of missed detections while a low va...

Prediction of future values of a shot noise process observed on a discrete lattice of points is considered. The shot magnitudes are assumed to be independent and identically distributed and arrive via a Poisson process; the eeect of each shot dissipates and/or accumulates according to a known shot function. Conditional mean and linear point predictors of future process values are developed. Dis...

The behavior of power-law shot noise, for which the associated impulse response functions assume a decaying power-law form, is explored. Expressions are obtained for the moments, moment generating functions, amplitude probability density functions, autoCorrelation functions, and power spectral densities for a variety of parameters of the process. For certain parameters the power spectral densit...

Suicide bombings are the leading cause of death from terrorism in Israel. Counterterror tactics, such as the targeted killings or preemptive arrests of terror leaders or suspects, are meant to prevent such attacks. To investigate whether these tactics are successful, we estimated via maximum likelihood a family of shot-noise models from monthly data covering 2001 through 2003 to see whether we ...
