With the increased use and advances in the field of wireless networking, many issues are being confronted. One major issue is the transmission of video and audio over wireless networks. In wireless mobile networks, the range of possible scenarios, and the traffic load generated by their typical applications give principal key aspects that make challenges to(More)
This paper presents a new approach to support evaluating a set of objects on a hierarchy of qualitative criteria. Evaluating an object on a node with respect to its evaluations on the sub-nodes is formulated as a multicriteria classification problem where the levels of the node's scale correspond to the ordered classes. Different multicriteria(More)
The effects of milling asmachining process and a post-machining treatment bywire-brush hammering, on the near surface layer characteristics of AA 5083-H111were investigated. Surface texture, work-hardening and residual stress profiles were determined by roughness measurement, scanning electron microscope (SEM)examinations,microhardness andX-raydiffraction(More)
Machining defects as rebuilt material and dislodgement were often induced by cutting of difficult to machining AISI 304 stainless steel. Their density increases with a decreasing of cutting speed. The effect of these defects on surface topography and residual stress was evaluated by roughness and X-ray diffraction measurements coupled with numerical(More)
