“…The continuity requirement refers to the continuity of the two-cutting trajectory of the shearer before and after, which is height difference of two sampling points along the feed direction of the shearer (above or below) before and after the cutting trace. It is also the requirement of maximum amount of adjustment along the feed direction before and after the shearer cutting height [14].…”

In order to solve the current situation that under geological change, the shearer cannot self-adaptively adjust to the memory of the cutting track, thereby reducing the efficiency of the coal shearer, an adaptive 3D fine geologic model based on the method of complex geological structures is proposed. In the study, a mathematical model of the cutting trajectory of the shearer drum is set up by three coordinate transformations, and the relatively high precision of the cutting trajectory of the shearer drum is obtained. Then, the circular coordinate transformation method is used to plan the cutting path of the shearer, and the calculation formula of the adjustment and the angle of the pitch angle for every shearer of the shearer is derived. In the end, according to the requirements of the mining technology of the shearer, the correction method of the theoretical planning path of the shearer based on the interpolation algorithm and the cyclic coordinate transformation algorithm is put forward. The research shows that the method proposed in this paper can not only adapt to complicated geological structures such as folds, but it also can achieve greater recovery rate.

“…The improving map that reduces task scheduling and micro-partitioning mechanism was proposed by the authors of article [14] for mobile cloud multimedia services. The authors of article [15] proposed a dual mode self-adaption handoff mechanism for multimedia services in mobile cloud computing environment to improve handoff quality and minimize utilized bandwidth. An adaptive modulation coding technique with cross-layer mapper module is proposed in article [16] for enhancing the quality of service, which is used to realize the main bottleneck parameters for the multimedia applications such as bandwidth, delay, and throughput.…”

In order to improve the quality of multimedia communication and experience, we proposed a crowd service cooperation control protocol based on the opportunistic wavelet model. Firstly, in order to provide real-time and reliable guarantee for mobile multimedia services, we analyze the delay, jitter, and distortion of wireless multimedia streams transmission based on wavelet model. The method of video frame resolution analysis and wavelet scale space is combined to establish a wavelet multimedia mobile analysis model. Secondly, the crowd service plan was proposed to correctly decode and compensate the video frame in the mobile multimedia receiver. Finally, the cooperative control of crowd services was proposed to address the distortion competition problems of the video frame sequence. A set of experimental results demonstrate the capability of video frame quality assurance for mobile multimedia crowd service cooperation control protocol. Another group of comparative analysis of the experiment results fully demonstrate the mobile multimedia crowd service cooperative control protocol can provide the higher system throughput and smaller delay compared with the guarantee mechanism of multimedia quality of service based on wavelet analysis.
