this study aimsto investigate an aspect of marital interactions, distance. by applying aqualitative method and conducting 43 in-depth semi-structured interviews, including 22women and 21 men, women and men experiences of distance were investigated based on theirown narratives.the results of the study suggested different forms of distance in couples' relationships,which can be classified to...

The optimum road spacing has been studied by many researches. It is an important step of forest road network planning. The goals of this study are determining the optimum road spacing in Kheiroudkenar forest of Nowshahr in Northern Iran and study of effect of kind of skidder on skidding cost and road spacing. Continues time study method was used to determine the production rate of TAF and Timbe...

Cities are structured by roads. Having up to date and detailed maps of these is thus an important challenge for urban planing, civil engineering and transportation. Those maps are traditionally created manually, which represents a massive amount of work, and may discard recent or temporary changes. For these reasons, automated map building has been a long time goal, either for road network reco...

An improved hierarchical fuzzy inference method based on C-measure map-matching algorithm is proposed in this paper, in which the C-measure represents the certainty or probability of the vehicle traveling on the actual road. A strategy is firstly introduced to use historical positioning information to employ curve-curve matching between vehicle trajectories and shapes of candidate roads. It imp...

Executive Summary: In this project our group set out to determine what effect, if any, an air monitor's distance from the roadway had on the measured air pollution levels of carbon monoxide, nitrogen dioxide, and fine particulate matter (PM2.5). The group was also searching to see if we could identify pollution emitters using wind data. "Fine particles," such as those found in smoke and haze, a...

BACKGROUND Road running is a growing sport. OBJECTIVES To determine the prevalence of sports-related dermatoses among road runners. METHODS Cross-sectional study of 76 road runners. Assessment was performed by means of a questionnaire, interview, and clinical examination. The chi-square and linear trend tests were used for analysis. RESULTS Most athletes were men (61%), aged 38±11 years, ...

This paper presents a high accuracy stereovision system for obstacle detection and vehicle environment perception in various driving scenarios. The system detects obstacles of all types, even at high distance, outputting them as a list of cuboids having a position in 3D coordinates, size, speed and orientation. For increasing the robustness of the obstacle detection the non-planar road model is...

the aerodynamics of road vehicles has frequently been studied in simplified geometries to separate the effect of various components on aerodynamic drag and on near wake flow dynamics. in this work, the characteristics of the near wake of a notch-back car model were investigated, using hot-wire anemometer. the main objectives of this study are to gain a better understanding of the flow structure...
