In signal processing, four functions of one variable are commonly used. They are the signal in time, the spectrum, the auto-correlation function of the signal, and the auto-correlation function of the spectrum. The variables of these functions are denoted, respectively, as time, frequency, lag, and doppler. In time-frequency analysis, these functions of one variable are extended to quadratic fu...
in this paper, the problem of finite time stabilization for guidance system is investigated and a novel nonlinear guidance law against maneuvering targets is proposed based on the principles of parallel navigation. the proposed law is developed using two variable structure control techniques. by applying finite time integral sliding mode and combining it with terminal sliding mode, a new guidan...
Abstract We study minimization of a structured objective function, being the sum smooth function and composition weakly convex with linear operator. Applications include image reconstruction problems regularizers that introduce less bias than standard regularizers. develop variable smoothing algorithm, based on Moreau envelope decreasing sequence parameters, prove complexity $${\mathcal {O}}(\e...
Literature review related to nonrenewable resources shows that technological improvements have considerable effects on resource depletion and decreasing operational cost. Therefore it is assumed that technology is the most important and influential variables in the production function and utilization cost of these resources. In this study, we assess the long term effect of technology diffusion...
ANFIS systems have been much considered due to their acceptable performance in terms of creation of fuzzy classifier and training. One main challenge in designing an ANFIS system is to achieve an efficient method with high accuracy and appropriate interpreting capability. Undoubtedly, type and location of membership functions and the way an ANFIS network is trained are of considerable effect on...
