Human mobility is a complex pattern of movements and activities that are based on some underlying semantics of human behavior. In order to construct accurate models of human mobility, this semantic behavior needs to be unearthed from the data sensed as a human being moves around and visits certain classes of locations such as home, work, mall, theater, restaurant etc. The ideal data for underst...

This correspondence deals with the problem of determining the source coherency structure and estimation of directions of arrival in the presence of coherent signals. The method is closely related to the smoothed rank profile (SRP) algorithm presented in [3], which Manuscript received July 20, 1987; revised October 3, 1988. This work was supported by the Naval Physical and Oceanographic Laborato...

Neuropsychological and psychophysical studies report controversial results regarding local-global visual processing and motion perception in autism. Here, we investigate contour integration and motion perception in an accurately diagnosed sample of autistic children, using low-level psychophysical tasks. We measured detection thresholds for a closed chain of Gabor patches, for different values ...

We present a new approach to display High Dynamic Range (HDR) video using gradient based high dynamic range compression. To obtain HDR video, we utilize the split aperture camera. We apply a spatio-temporal gradient based video integration algorithm for fast and accurate integration of the three input HDR videos into a low dynamic range video, which is suitable for display. The spatiotemporal v...

This letter propose a new method based on covariance sparse target recovery for Direction of Departure (DOD) and Direction of Arrival (DOA) in bistatic multi -input multi-output radar. The letter use this property that the number of target in the space is low. In this paper we recover the power of incident signal as a diagonal matrix which its diagonal element are corresponding to the impinging...

Abstract Complex stress states due to torsion lead dislocation structures characteristic for the chosen axis. The formation mechanism of these and link overall plastic deformation are unclear. Experiments allow analysis cross sections only ex situ or limited in spacial resolution which prohibits identification substructures form within volume. Discrete dynamics simulations give full access stru...

Recent measurement and simulation studies have revealed that wide area network traffic has complex statistical—possibly multifractal—characteristics on short timescales, and is self-similar on long timescales. In this paper, using measured TCP traces and queueing simulations, we show that the fine timescale features can affect performance substantially at low and intermediate utilizations, whil...
