guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

Wireless power transfer is applied to small mobile robots. Since the fluctuation of received voltage a problem in wireless robots, suppression focused. In magnetic resonant coupling method, it necessary match frequency primary side with that secondary side. The high Q value resonator causes due changes load and/or distance. To solve this problem, automatic tuning assist circuit (ATAC) adopted a...

Social media allows people interact to express their thoughts or feelings about different subjects. However, some of users may write offensive twits to other via social media which known as cyber bullying. Successful prevention depends on automatically detecting malicious messages. Automatic detection of bullying in the text of social media by analyzing the text "twits" via one of the machine l...

Automatic fault localization is essential for software engineering. However, suffers from the interactions among multiple faults. Our previous research revealed that fault-coupling effect responsible weakened performance in multiple-fault programs. On basis of this finding, we propose a Test Case Restoration Method based on Genetic Algorithm (TRGA) to search potential coupling test cases and co...

Article history: Received 18 April 2015 Accepted 16 July 2015 Available online 28 July 2015 Editor: M. Cvetič Massive gravity (mGR) describes a dynamical “metric” on a fiducial, background one. We investigate fluctuations of the dynamics about mGR solutions, that is about its “mean field theory”. Analyzing mean field massive gravity (mGR) propagation characteristics is not only equivalent to st...

in order to improve the performance of irrigation networks, provide higher flexibility levels and improve water delivery methods, application of automatic control systems is suggested. in the coarse of the present study, a mathematical model of automatic pivot weir as based on pid control logic in combination with icss hydrodynamic model is developed. the developed model was tested under high f...

Zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (TMVS) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. Then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...
