The assessment of the level and content of consciousness in brain-damaged patients relies to a large extent on behavioral assessment techniques. The limited behavioral repertoire displayed by vegetative and minimally conscious states requires the use of highly sensitive and reliable behavioral assessment methods, allowing the detection of subtle changes in behavior and associated level of consc...

This paper addresses the implementation of a 2-D Discrete Wavelet Transform on general-purpose microprocessors, focusing on both memory hierarchy and SIMD parallelization issues. Both topics are somewhat related, since SIMD extensions are only useful if the memory hierarchy is efficiently exploited. In this work, locality has been significantly improved by means of a novel approach called pipel...

In this paper we present techniques for the efficient generation of a level-of-detail (LOD) data structure for large scale point-based surface representation and rendering. Our approach generates a spatial partitioning hierarchy of irregular point samples in 3D space, and we provide an efficient point-octree LOD generation algorithm. Using the concept of transformation-invariant homogeneous cov...

Dimension hierarchies represent a substantial part of the data warehouse model. Indeed they allow decision makers to examine data at different levels of detail with On-Line Analytical Processing (OLAP) operators such as drill-down and roll-up. The granularity levels which compose a dimension hierarchy are usually fixed during the design step of the data warehouse, according to the identified an...

This research applies formal dataflow analysis and techniques to high-level DFT. Our proposed approach improves testability of the behavioral-level circuit description (such as in VHDL) based on propagation of the value ranges of variables through the circuit’s Control-Data Flow Graph (CDFG). The resulting testable circuit is accomplished via controllability and observability computations from ...

Objective: The present study aims at investigating the effects of behavioral therapy techniques through operant conditioning and observational learning on children’s aggression aged 4-6 years.  Methods: To this end, a pretest-posttest quasi-experimental study with two experimental groups and a control group was designed. We used non-probability purposive sampling method to select 45...
