To improve the thermal design of vehicle-integrated photovoltaic (VIPV) modules, this study clarifies characteristics convective heat transfer coefficient h between vehicle roof surface and surrounding air with respect to speed. Experiments on two types vehicles different body shapes indicate that is strongly affected by speed, it also shape depending position roof. Empirical equations for appr...

Point cloud semantic segmentation has played an important role in the scan-to-BIM process of Ming and Qing Dynasties’ official-style architecture roof. To overcome complexity roof components’ shape scale differences between different component types, a point method for MQDOAs considering construction regulations is proposed this paper. This composed two stages. In first stage, features from rul...

The phenotypic appearance of the head of animal species depends strongly on the shape of the skull. The present study has been carried out on morphological and radiographic characteristics of skull of the Indian Blackbuck. The skull comprised of cranial and facial bones. The cranial bones included occipital, sphenoid, ethmoid, interparietal, parietal, frontal and temporal. The occipital was a s...

We attempted to define the central nervous system (CNS) concomitants of various types of orbital fractures in children by reviewing the records of 95 inpatients with admission diagnoses including orbital fracture who presented to the Children's National Medical Center from 1987 through 1994. Patients were divided into three age groups: group I: 0-5 years; group II: 6-12 years; group III: older ...

The U.S. National Institute for Occupational Safety and Health (NIOSH) conducted a study to determine the effectiveness of a filtered air delivery system to reduce respirable dust exposure of roof bolter operators in underground coal mines. When performing roof bolting operations, roof bolter operators may experience exposure to high levels of respirable dust during a working shift, especially ...

In February 2006, an outbreak of Legionnaires' disease (LD) was identified in Beachlands, a small, isolated east Auckland suburb. It was investigated through case finding, a case-control study, sampling potential sources of infection and by molecular typing (using sequence-based typing (SBT) of all Legionella pneumophila serogroup 1 (Lp1) isolates). Lp1 was isolated from the respiratory tract o...

Laser scanning is a new technology for obtaining Digital Surface Models (DSM) of the earth surface. It is fast method for sampling the earth surface with a high density and high point accuracy. In this paper a procedure for building detection and roof extraction from the DSM is presented. The procedure starts by re-sampling elevation as obtained by laser scanning into regular grid. The core par...

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof residential buildings are investigated based on the simulation of turbulent air flow and natural convect...

In this paper, a methodology is proposed for the geometric refinement of LiDAR building roof contours using high-resolution aerial images and Markov Random Field (MRF) models. The proposed methodology assumes that the 3D description of each building roof reconstructed from the LiDAR data (i.e., a polyhedron) is topologically correct and that it is only necessary to improve its accuracy. Since r...
