This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...

conclusions the dominant side scapula of asymptomatic racquet players showed increased external rotation and elevation as compared to the non-dominant side. also, reduced shoulder internal rotation, extension and adduction and gain in shoulder external rotation was observed on the dominant side of racquet players when compared to the control group. materials and methods 46 asymptomatic professi...

toluidine blue o (tbo) is a cationic dye which is extensively used in the industries. in the present paper a simple and efficient wet chemical method was introduced for removal of tbo from waste aqueous solution. magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

in the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. the cranial cervical ganglion was found beneath the mandibular salivary gland. it was located ventromedial to tympanic bulla and ventrally to atlantic fossa. in three out of eight animals it wa...

the architectural education along the way of creativity has often involved with the formal and physical aspects of design as an effort to read architectural artifacts through its mere external appearances. this article, however, aims to step beyond the manifestation of conventional perspectives on visual aspects of built environment. that is, an act of interpreting the architectural spaces thro...

knowledge is one of the most important accomplishments of human being in confrontation with phenomena and facts whichhe acquires through his cognitive faculties. throughout the history of philosophy, there was always this confusion that whether or not beliefs are influenced by his non-epistemic areas and external elements, and if so, is it epistemically acceptable or the agent should avoid thes...

Software reuse can lower costs and increase the flexibility of the software development process. Despite a large body of research focused on technical factors, there is still limited research on how companies reuse exiting components. In this study, we analyzed the reuse of external software components by taking a contingency approach. Using a survey of IT managers in the software industry, we ...
