In recent years, the scanning of real-world physical objects using 3d acquisition devices has become an everyday task. Such 3d scanners output a set of three-dimensional points, called point cloud, sampling the surface of an object. These samples are typically subject to imperfections like noise, holes and outliers. In computer graphics, the field of surface reconstruction is concerned with the...

In every production parallel processing environment, the set of resources potentially available to an application uctuate due to changes in the load on the system. This is true for clusters of workstations which are an increasingly popular platform for parallel computing. Today's parallel programming environments have largely succeeded in making the communication aspect of parallel programming ...

In this chapter we investigate the role of motor cortex in adapting movements to novel dynamic environments. We present results from two experiments in which monkey or human subjects learned to make two-dimensional reaching movements while holding a robotic manipulandum that applied a predictable pattern of forces (a curl field) to their hand. In the first study, we analyzed electrophysiologica...

This paper describes the simulation setup applied in an introductory study in connection with implementation of subsea processing equipment at an already operating gas and oil field. The primary aim of the subsea processing equipment is to increase the oil recovery, but it is also considered as an important technological step forward. A subsea separation and boosting station is planned installe...

Heterogeneous and resource-constrained sensors, computational and communication latencies, variable geospatial deployment and diversity of applications set challenges for sensor network middleware. RESTful architecture principles have been widely applied in middleware design. The new Computational REST architecture offers additional set of principles. In Computational REST, computations are see...

abstract the character element, as the main construction fund of every story, plays a significant role in the procedure of processing the plot, shaping the events and moving forward in any narrative text. the book of “al-avasef” written by gibran contains some short stories in which the author considers and cares about character element and methods of its processing. in the present study, with ...

Executive cognitive functions have been postulated to include both dynamic behavioral selection and strategic goal-setting or response preparation. To investigate the relation between these aspects of executive processing, we embedded an event-related oddball paradigm within a blocked design. Subjects responded to infrequent targets presented within a series of standard stimuli that required no...

Coded ultrafast optical pulses can be treated as onedimensional (1-D) images in the time domain. We have converted space-domain images into time-domain images using diffraction from dynamic holograms inside a Fourier pulse shaper, with photorefractive quantum wells (QW’s) used as the dynamic holographic medium. We present several examples, in which amplitude or phase modulation of the hologram ...

Progressive processing plans allow systems to tradeoff computational resources against the quality of service by specifying alternative ways in which to accomplish each step. When the structure of a plan is known in advance, it can be optimally scheduled by solving a corresponding Markov decision process. This paper extends this approach to dynamic scheduling of plans that can be constantly mod...

HighlY constrained backPRojection (HYPR) is a promising image-processing strategy with widespread application in time-resolved MRI that is also well suited for PET applications requiring time series data. The HYPR technique involves the creation of a composite image from the entire time series. The individual time frames then provide the basis for weighting matrices of the composite. The signal...
