The use of joint properties and mapping techniques are key for fall ground management in underground mining. This paper outlines the probabilistic design approach addressing potential falls ground, based on identified keyblocks. A shallow chrome mine was used as a case study to identify causes with aim improving existing system. system comprises visual observations, Ground Penetrating Radar (GP...

Replication of human hand motions on anthropomorphic robotic hands is typically treated in literature as the combination two sub-problems: measurement motions, and mapping such hand. In this letter we focus second one. Different approaches have been proposed to deal with problem, but none them preserves both master finger shapes fingertip positions hand, i.e. ensuring predictability natural mot...

aim: abnormal joint mobility is an important factor in movement dysfunction and physical disability. a general lack of descriptive details exists for measurements of hip rotation range of motion (rom). this study was designed to establish the influence of hip position on active and passive range of motion of the hip in external and internal rotation(ext & int rot). material & methods: ...

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...

abstract   background: sacroiliac joint (sij) dysfunction is a widely known but poorly defined   cause of low back pain. to our knowledge, few published studies have been   conducted to evaluate systematically the prevalence and significance of concomitant   sacroiliac joint dysfunction in patients with herniated lumbar discs. as concomitant   sij dysfunction in low back pain patients is likely...

A feedforward spiking network represents a nonlinear transformation that maps a set of input spikes to a set of output spikes. This mapping transforms the joint probability distribution of incoming spikes into a joint distribution of output spikes. We present an algorithm for synaptic adaptation that aims to maximize the entropy of this output distribution, thereby creating a model for the join...

The classic mapping metaphor posits that children learn a word by mapping it onto a concept of an object or event. However, we believe that a mapping metaphor cannot account for word learning, because even though children focus attention on objects, they do not necessarily remember the connection between the word and the referent unless it is framed pragmatically, that is, within a task. Our th...

During emergency response, individuals observe only part of the picture, sharing of information is needed to get the required complete picture. The aim of our study is to get insight in the collaborative mapping process in order to derive requirements for a map-sharing tool. First, we analyzed the domain to assess the mapping processes, to identify general problem areas of the assessed processe...
