determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولSOlt POTASH-POTASH INVESTIGATION-POTASH DEFICIENCIES
It is in this connection that it becomes very difficult at times for the agricultural scientist and practical agriculturist to meet on common ground, for very often a popular version of scientific reasoning may appear ambiguous, and in this case it would appear better to sacrifice the facile version (since the layman can always get an interpreter to explain if he is sufficiently interested) tha...
متن کاملSuitable measures against the pollution of the Rhine by chloride discharge from the Alsatian potash mines.
A great number of organic and inorganic substances pollute the water of the Rhine. The greatest concentration is formed by the chlorides, as their quantity exceeds that of the suiphates by about 50 per cent. At the German—Dutch frontier, the mean annual value of the chloride charge of the river amounts to approximately 350 kg/s C1. About 40 per cent, or 130 kg/s, of this quantity are residual s...
متن کاملDevelopment experience of ore extraction and traffic simulation system in potash mines – bundled software “Рудопоток”
Development experience of ore traffic and extraction simulation system in underground part of potash mines is reviewed. Distinctive features of suggested simulation model (combine complex extraction, using conveyor transport and transfer point in continuous ore traffic simulation) are represented. Implementation features of bundled software ”Рудопоток” are considered.
