The performance of a type of fuzzy sliding mode control is researched by considering the nonlinear characteristic of a missile-target interception problem to obtain a robust interception process. The variable boundary layer by using fuzzy logic is proposed to reduce the chattering around the switching surface then is applied to the interception model which was derived. The performances of the s...

this research was carried out in order to quantify throughfall (tf) and interception loss (i) and to compare the chemical composition of tf, i.e. lead (pb) and cadmium (cd) as well as electrical conductivity (ec) and ph beneath pinus eldarica and cupressus arizonica plantations and the open field rainfall. the research was accomplished in the chitgar forest park, a semi-arid polluted urban area...

In this paper, a solution is presented for a robotic manipulation problem in industrial settings. The problem is sensing objects on a conveyor belt, identifying the target, planning and tracking an interception trajectory between end effector and the target. Such a problem could be formulated as combining object recognition, tracking and interception. For this purpose, we integrated a vision sy...

one of the main components affecting the ecohydrology is interception or loss of rainfall by plant canopy. interception of reduced effective precipitation and dry areas to prevent soil moisture. low level of abstraction is considered as important factors in managing rangeland resources. in this study, the vegetative form, some broad-leaved plants and plant selection and method of abstraction in...

Communications Interception is an essential part of law enforcement used by authorised government agencies to investigate criminal activities. With the growth of IP based applications and new IP technologies such as mobile IP, Internet Service Providers (ISPs) will find themselves increasingly obliged to provide interception capabilities. IP interception is usually done with expensive hardware ...

An interception model that links the temporal variability of rainfall with the storm-based description of the interception process is derived. Analytical formulae for long-term interception loss are obtained for precipitation with statistical characteristics derived from observations. The analysis of the results indicates that the point interception loss is controlled primarily by three time sc...

Eye movements aid visual perception and guide actions such as reaching or grasping. Most previous work on eye-hand coordination has focused on saccadic eye movements. Here we show that smooth pursuit eye movement accuracy strongly predicts both interception accuracy and the strategy used to intercept a moving object. We developed a naturalistic task in which participants (n = 42 varsity basebal...

in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...
