A moving window technique for the finite element time domain (FETD) method is developed to simulate the propagation of electromagnetic waves induced by the transit of a charged particle beam inside large and long structures. The window moving along with the beam in the computational domain adopts high-order finite-element basis functions through p refinement and/or a high-resolution mesh throug...

We measured the microvascular response to histamine in guinea pig skin. Histamine (40 mg ml(-1)) was given either as a skin prick test or applied topically onto a skin window. The skin window was prepared by applying suction and gentle warming to the skin so that a blister was formed, and by removing the top of the blister. The microvascular response was measured as the accumulation of radiolab...

The combination of postextraction ridge resorption [1] and pneumatization of the maxillary sinus [2, 3] often limits the bone available for implant placement in the posterior maxilla. Fortunately, the lateral and transcrestal approaches to sinus floor elevation (SFE) and augmentation can reproduce adequate subantral bone volumes for implant-supported rehabilitation in this region. The lateral w...

The possibility of using window comparators for the on-chip evaluation of signals in the analogue circuit part has been demonstrated and is shortly summarised. One of the problems is the lot-to-lot variation of the comparator window. An automatic window repositioning technique is detailed that allows to compensate the window shift. The components for the implementation comprising a reference co...

Abstract—In signal processing, there are mainly two types of filters exist and the are Finite Impulse Response(FIR) filter and Infinite Impulse Response(IIR) filter. Finite Impulse Response(FIR) filter can be designed form Infinite Impulse Response(IIR) filter by various techniques. The widely used technique is the window technique. In this paper, the designing analysis of FIR filter are shown ...

OBJECTIVES Accurate mu maps are important for quantitative image reconstruction in SPECT. The Compton scatter energy window (CSW) technique has been proposed to define the outline of objects. In this technique, a lower energy window image is acquired in addition to the main photo-peak energy window. The image of the lower energy window is used to estimate the edge of the scanned object to produ...

This report describes a novel window matching technique. We perform window matching by transforming image data into sparse features, and apply a computationally efficient matching technique in the sparse feature space. The gain in execution time for the matching is roughly 10 times compared to full window matching techniques such as SSD, but the total execution time for the matching also involv...

AIM The aim of this study was to investigate the influence of calcium hydroxide dressing on the filling of simulated lateral canals by different obturation techniques. MATERIALS AND METHODS Sixty single-root-premolars were instrumented. Simulated lateral canals were drilled on each third of the roots. The teeth were divided into four groups: no dressing and obturation by lateral condensation ...
