The fractional cosine and sine transforms – closely related to the fractional Fourier transform, which is now actively used in optics and signal processing – are introduced and their main properties and possible applications are discussed.

Compressing the image causes less memory to be used store images. images increases transmission speed of compressed in network. Vector quantization (VQ) is one compression methods. The challenge vector method for non-optimization codebooks. Codebook optimization quality and reduces volume Various methods swarm intelligence meta-heuristics are improve algorithm, but using meta-heuristic based on...

In order to maintain the power quality, parameters of harmonic and sub-inter-harmonic components in signal must be estimated accurately with less computational complexity. systems, value fundamental frequency changes between 49.5Hz 50.5Hz this situation causes other change. make efficient amplitude phase estimation, initially, frequencies properly. study, Sine Cosine Algorithm is applied for es...

In recent times, renewable energy sources are essential for generating low-cost, pollution-free power. Since the last two decades, hydrothermal coordination system has been used to fulfill demand The traditional model's biggest flaws high generation cost and excessive fossil fuel emission. proposed work, process of scheduling (HTS) improved by integrating wind–solar energy. To overcome current ...

China consumes significant amount of natural gas in winter. The integrated community energy utilization system (ICEUS) cannot stabilize the output electricity and heat if there is a shortage gas. operation cost still needs improvement. An supply structure using garbage power as core ICEUS was established study. optimal dispatching model regulating characteristic load. sine-cosine algorithm (SCA...

The optimal performance of a wireless mesh network (WMN) can be greatly improved by strategically placing routers. As result, it is crucial to optimally locate the WMN routers for better coverage and connectivity. Besides placement, congestion due overlaying has taken into consideration. These issues have become motivation researchers identify variety approaches optimize performance. Multiple m...

It is a classical problem in Fourier analysis to give conditions for a single sine or cosine series to be uniformly convergent. Several authors gave conditions for this problem supposing that the coefficients are monotone, non-negative or more recently, general monotone. There are also results for the regular convergence of double sine series to be uniform in case the coefficients are monotone ...

This paper studies the heat transfer analysis caused due to free convection in a vertically oscillating cylinder. Exact solutions are determined by applying the Laplace and finite Hankel transforms. Expressions for temperature distribution and velocity field corresponding to cosine and sine oscillations are obtained. The solutions that have been obtained for velocity are presented in the forms ...
