BACKGROUND Collision geocoding is the process of assigning geographic descriptors, usually latitude and longitude coordinates, to a traffic collision record. On California police reports, relative collision location is recorded using a highway postmile marker or a street intersection. The objective of this study was to create a geocoded database of all police-reported, fatal and severe injury c...

One of the factors which are usually difficult to be measured in mills is the grindability and distribution of feed under real situation and in a short time. In the condition of achieving a fast and convenient way to determine these parameters, the proper relationship between energy, hardness and particle size distribution can be obtained. Feed hardness is one of the most important factors in g...

frothers havea profoundeffectonbubble size and also flotation efficiency. in present study the effect of type and dosage of frothers on the flotation response of coarse particles of quartz was investigated.  therefore, flotation response of coarse particles using frothers such as mibc, pine oil, poly propylene glycol with concentration of 0, 25, 50 and 75 g/t, was obtained respectively. for all...

One of the most important aspects in interactive virtual environment applications is maintaining interactive frame rates while providing realistic and believable experience. Due to this fact, collision detection for interactive virtual environment applications acts as an important part of the system. However, due to its computationally intensive nature, collision detection can become a bottlene...

Safe physical human-robot interaction gains importance since bringing humans and robots spatially working together provides a high benefit for industry. Here robots can aid humans e.g. as "third hand" or by performing monotonous tasks. To realize this, a certain level of safety has to be ensured. A lightweight design and inherent passive compliance, as present at the BioRobArm, helps to reduce ...

A stochastic droplet collision model (Sommerfeld [9]), based on the creation of a fictitious collision partner is described, taking into account impact efficiencies. The model of O’Rourke [5] is considered to predict the outcome of water-droplet collisions, being grazing or coalescing, and to predict post-collision velocities. The relevance of impact efficiencies is discussed for water droplet ...
