little is known about survival, longevity, dispersal, and social organisation of tree weta in the wild (Trewick and Morgan-Richards, 1995). Their relatively large size for an insect allows tree weta to be easily tagged. This, plus their flightlessness, potentially makes them ideal species for mark-recapture studies. The mountain stone weta, Hemideina maori (Pictet and Saussure), is unusual for ...
This paper focuses on the probabilistic numerical solution of the problems in mining, machine industry and biomechanics. Theory and applications of the Simulation-Based Reliability Assessment (SBRA) method are presented in the solution of the hard rock (ore) disintegration process (i.e. the bit moves into the ore and subsequently disintegrates it, the results are compared with experiments, new ...
The hard rock stratum will seriously affect the efficiency of deep-sea drilling and greatly increase cost operations due to its complexity. In ocean operations, design bit is critical. Therefore, core should be able drill in a variety formations, especially stratum, with function reducing need change formation changes improving efficiency. this paper, three different bits were designed accordin...
As parallelism in microprocessors becomes mainstream, new programming languages and environments are emerging to meet the challenges of parallel programming. To support research on these languages, we are developing a lowlevel language infrastructure called Pillar (derived from Parallel Implementation Language). Although Pillar programs are intended to be automatically generated from source pro...
