Computerized path planning, not constrained to transportation networks, may be useful in a range of settings, from search and rescue to archaeology. This paper develops a method for general path plann...
Recently, due to the increased penetration of smart devices and the development of geographic information system (GIS) technology, various route guidance services for pedestrians have been developed. ...
GIS applications in the commercial sector have by large been concentrated on location query, optimal product routing and distribution. There is a scarcity of research and implementation of the geo-inf...
For Paul Torrens, wintry weather is less about sledding and more about testing out models of human behavior.Torrens, a geographer at the University of Maryland, studies how snow and icy conditions aff...
This study presents a newly developed simple and cordless system, that consists of a gyro sensor and is connected to a small easily wearable personal computer (WPC) of a wrist watch type. The lithium ...
Potential influences on explaining walking distance from home to access public transport are investigated, including trip and demographic characteristics and public transport supply. In Sydney, Austra...
Annually, in Australia, 10–15% of all road-related fatalities involve pedestrians. Of those pedestrians fatally injured, approximately 45% were walking while intoxicated or ‘drink walking’. Drink walk...
Dynamically adapt to uneven ground locomotion is a crucial ability for humanoid robots utilized in human environments. However, because of the effect of current pattern generation method, adapting to ...
Recent literature on walking robots deals predominantly with multi-degrees-of-freedom leg mechanisms and machines capable of adopting several gaits. This paper explores the other end of the spectrum s...
More and more biological evidences have been found that neural networks in the spinal cord, referred to as “central pattern generators” (CPGs), govern locomotion. CPGs are capable of producing rhythmi...

Historical maps, aerial images and other historic documents are finding their way into the digital world. This offers new possibilities but also requires adapted technologies and interdisciplinary app...
阐述了自走式棉秆联合收获机的基本结构及工作原理,对总体结构、底盘配置及喂入切碎机构进行了设计和参数计算,采用纵向对称配置、简化喂入机构、交错对称布置切碎滚筒动刀等方法,实现了棉秆收割、切碎、集箱、自卸的一体化。试验结果表明作业流程安排合理,适用性较好,是棉秆资源规模化工业利用的适用设备。
To assess the design of walking infrastructure such as transfer stations, shopping malls, sport stadiums, etc., as well as to support planning of timetables for public transit, tools to aid the design...
提出了基于改进随机Hough变换(RHT)的收获机器人行走目标直线检测算法。将摄像机安装在联合收获机的顶部,在收获过程中采集农田场景图像。根据已收获区域、未收获区域和非农田区域的不同颜色特征,利用统计分析和边缘检测,确定行走目标直线的终点位置以及直线方向上的候选点。以候选点为点集,采用改进RHT完成直线检测。与传统的RHT相比,避免了无效采样和累积问题。经过对多幅图片的处理,证明算法能够有效检测出...
