We propose non-stationary spectral kernels for Gaussian process regression. Wepropose to model the spectral density of a non-stationary kernel function as amixture of input-dependent Gaussian process frequency density surfaces. Wesolve the generalised Fourier transform with such a model, and present a familyof non-stationary and non-monotonic kernels that can learn input-depende...

This article explores the existence of periodic solutions for nonautonomous impulsive semi-ratio-dependent predator-prey systems on time scales. Based on a continuous theorem in coincidence degree theory, sharp sufficient and necessary conditions are derived in which most popular monotonic, non-monotonic and predator functional responses are applicable. This article extends the work in [6, 10, ...

This paper considers identical parallel machines scheduling problem with past-sequence-dependent setup times, deteriorating jobs and learning effects, in which the actual processing time of a job on each machine is given as a function of the processing times of the jobs already processed and its scheduled position on the corresponding machine. In addition, the setup time of a job on each machin...

The single machine coupled task scheduling problem includes a set of jobs, each with two separated tasks, and there is an exact delay between the tasks. We investigate objective minimizing makespan under identical processing time for first period all time-dependent setting second task. Certain healthcare appointment problems can be modeled as problem. Also, incorporation lets human resource fat...

this paper presents the design procedure and implementation results of a proposed hardware which performs different satellite image compressions using fpga xilinx board. first, the method is described and then vhdl code is written and synthesized by ise software of xilinx company. the results show that it is easy and useful to design, develop and implement the hardware image compressor using ne...
