Security term in mobile ad hoc networks has several aspects because of the special specification of these networks. In this paper a distributed architecture was proposed in which each node performed intrusion detection based on its own and its neighbors’ data. Fuzzy-neural interface was used that is the composition of learning ability of neural network and fuzzy Ratiocination of fuzzy system as...
In this study, the formation of the Al3Ti intermetallic compound at the junction interface of aluminum-titanium was investigated during deposition and annealing. The results illustrated that during the deposition process, one thin layer of Ti3Al2 intermetallic compound was created at the junction interface. During the annealing at 550 °C, this layer was transformed to the Al3Ti interm...

Robot teleoperation systems face a common set of challenges including latency, low-dimensional user commands, and asymmetric control inputs. User control with BrainComputer Interfaces (BCIs) exacerbates these problems through especially noisy and erratic low-dimensional motion commands due to the difficulty in decoding neural activity. We introduce a general framework to address these challenge...
Brain-computer interfaces (BCIs) allow a user to directly control devices such as cursors and robots using brain signals. Non-invasive BCIs, e.g., those based on electroencephalographic (EEG) signals recorded from the scalp, suffer from low signalto-noise ratio which limits the bandwidth of control. Invasive BCIs allow fine-grained control but can leave users exhausted since control is typicall...
This study aimed to investigate the effect of electron beam welding parameters on the microstructural characteristics and mechanical properties of the dissimilar joint between 17-4PH precipitation hardening stainless steel and Ti6Al4V alloy. For this purpose, the welding of these two alloys was done without an interlayer and with an interlayer of copper with a thickness of 0.8 mm. Two different...
In this article, we investigate the redistribution of implanted As+ ion and effect of it on the rate of oxide growth during steam oxidation of Si wafers at 900oC. Our results show that a highly enriched, thin layer of Arsenic forms at the interface between the oxide and the underlying Si. Also, the oxidation rate was found to increase depending on the depth distribution and dose of the implant...
introduction - les impuretes, meme en faibles teneurs, modifient beaucoup les proprietes physiques des metaux. ainsi, pour une etude profonde de ces proprie, tes , on a besion d'un metal extremement pur. la methode de la zone fondue a permis cette realisation . principe - dans la methode de purification dite de la «zone fondue» decouverte par pfann en 1952, une courte zone liquide est depl...
