In 2006 a consortium of twelve German partners -including some leading providers of industrial robotic technology components (RTCs)teamed up with some research institutes and universities to work on a joint publicly funded four year project called DESIRE. It is focused on service robots, which shall offer their services under unconstrained conditions in immediate proximity of users in everyday ...

Abstract Raw pine wood processing and especially its mechanical constitute a significant share among technological operations leading to obtaining finished product. Stable implementation of machining operations, ensuring long-term repeatable results depends on many factors, such as quality invariability raw material, technical condition equipment, adopted parameters work, qualifications experie...

We find a quantum group structure in two-dimensional motion of nonrelativistic electrons in a uniform magnetic field on a torus. The representation basis of the quantum algebra is composed of the quantum Hall wavefunctions proposed by Haldane-Rezayi at the Landau-level filling factor ν = 1/m (m odd). It is also shown that the quantum group symmetry is relevant to the degenerate Landau states an...

the time-optimal trajectory for an airplane from some starting point to some final point is studied by many authors. here, we consider the extension of robot planer motion of dubins model in three dimensional spaces. in this model, the system has independent bounded control over both the altitude velocity and the turning rate of airplane movement in a non-obstacle space. here, in this paper a g...

The study area is located within two regions. first site in Tikrit city (Tikrit University) represents gypsiferous soils and the second calcareous Erbil Governorate. Two pedons were chosen P1 (rainfed) P2 (cultivated), other P3 P4 ( cultivated) . showed presence of gypsum crystals spindle lenticular type with a length ranging between (0.2 -0.5) mm , pores vughs chamber, while dominance planer i...

La question « À quoi reconnaît-on un être humain ? » fait planer certain doute sur notre capacité à reconnaître la forme humaine dans les multiples apparences que peut revêtir vie. C’est fond de cette inquiétude sceptique, prenant acte du caractère instable, indistinct et pluriel vie humaine, s’élaborent trois anthropologies philosophiques ici mises en dialogue : celle Montaigne, Nietzsche Witt...

Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent var...
