A ray tracing based cellular coverage simulator has been parallelized in order to speed up excecution. The simulator has been developed for accurate prediction of radio wave propagation in urban microcells. It combines a vertical plane model simulating the wave propagation over the buildings and a horizontal plane model simulating the wave propagation in the street canyons between the buildings...

This paper presents a vehicle detection method which can divide overlap vehicles. The proposed method detects vehicles by finding vertical planes above a road plane. At first, two horizontal line segments adjacent vertically are detected in the present frame. Then, corresponding line segments are searched in the previous frame by a correlation matching. If the motion of these horizontal line se...

PURPOSE To analyze the relative position of the mandibular foramina (MnFs) in patients diagnosed with skeletal class III malocclusion. MATERIALS AND METHODS Computed tomography (CT) images were collected from 85 patients. The vertical lengths of each anatomic point from the five horizontal planes passing through the MnF were measured at the coronoid process, sigmoid notch, condyle, and the go...

GABAergic neurons of the thalamic reticular nucleus (nRt) provide thalamocortical relay neurons with feedback inhibition that influences sensory processing and thalamocortical rhythm generation. Mutual interactions between reticular neurons coordinate oscillatory activities developed within the network during normal sleep and in absence epilepsy, but the chemical versus electrical nature of the...

The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...

Coordinate systems are a central issue in computational neuroscience: are they explicitly represented at some reductive level of brain function, and if so, are they only trivial products of associated anatomic geometries? This investigation examined these questions in the neural network that holds eye position, the so-called oculomotor integrator. Since neural activity in the integrator is beha...

Various intra and extracranial cephalometric horizontal reference planes have been used to formulate diagnosis and plan individualized treatment for an integrated correction of the malocclusion. Aim: The aim of this study was to evaluate variability of intracranial reference planes, i.e sella-nasion, basion-nasion, Frankfurt horizontal, functional occlusal, mandibular and maxillary-mandibular b...

Vectorcardiograms were recorded by the Frank lead system in 203 cases of right ventricular hypertrophy (RVH) and 85 cases of posterobasal myocardial infarction (PBMI). Of the RVH cases, 33 were confirmed by autopsy and 135 by cardiac catheterization or surgery. Of the cases of PBMI, 12 were confirmed by autopsy and 48 had definite clinical episodes associated with enzymatic or serial electrocar...

OBJECTIVES The aim of this study was to determine whether the assessment of pursuit eye movements in patients in minimally conscious state (MCS) is influenced by the choice of the visual stimulus (study 1) and by the moving plane (study 2). METHODS Patients with MCS (MCS- and MCS+) in the acute (<1 month post-injury) or chronic (>1 month) setting were assessed. The Coma Recovery Scale-Revised...

The field of infrastructure rehabilitation and development requires a better understanding of soil-structure interactions. The interaction behaviour between soil and structures has mostly been investigated through theoretical and/or numerical analysis. This paper presents a series of experiments performed on an intermediate-scale physical model made of an instrumented silo. In contrast to most ...
