This paper presents kinematic control problem of In this paper we propose to treat SSMR a as system skid-steering mobile robot using practical smooth and timesubjected to non ideal nonintegrable constraint. Next, we varying stabilizer. The stability result is proved using Lyapunov formulate kinematic control law based on tunable oscillator analysis and takes into account both input signal satur...

Techniques of prevention locomotive wheelsets skidding were analyzed. The relevance using object modeling techniques to automate the design devices prevent is shown. main task solution which devoted article synthesis model technical solutions such devices, calculation and compilation matrices measures for inclusion, intersection similarity. As a result modeling, closest (prototype) was chosen, ...

The southeastern United States has a promising source for renewable energy in the form of woody biomass. To meet the energy needs, energy plantations will likely be utilized. These plantations will contain a high density of small-stem pine trees. Since the stems are relatively small when compared with traditional product removal, the harvesting costs will increase. The purpose of this research ...

Nacrtak In Italy, where conventional forests have a protective rather than productive purpose, some silvicultural operations as first and second thinning could be carried out in an economic way adopting systems based on small scale mechanization. Authors tested a system based on small scale mechanization for bunching and skidding operations, using an All Terrain Vehicle (ATV), a compact, agile ...

Osteochondral lesions are drilled with the aim of stimulating the growth of new cartilage to cover the defect (Pnidie 1959). This may be performed at arthrotomy or anthroscopically, but arthroscopic drilling is far from standard practice. Performed percutaneously, arthroscopic drilling by Kirschner wire can be hindered by difficulty with accurate placement, skidding off sclerotic bone and entan...
