The Cloud storage is the most important issue today. This is due to a rapidly changing needs and a huge mass of varied and important data to back up. In this paper, we describe a work in progress and propose a flexible system architecture for data storage in the Cloud. This system is centered on the Data Manager module. This module provides various functions such as the dispersion of data in fragments, encryption and storage of fragments... etc. This architecture proves to be very relevant. It ensures consistency between different components. On the other hand, it ensures the security and availability of data.

AbstractImportant dynamic processes in mechanobiology remain elusive due to a lack of tools to image the small cellular forces at play with sufficient speed and throughput. Here, we introduce a fast, interference-based force imaging method that uses the illumination of an elastic deformable microcavity with two rapidly alternating wavelengths to map forces. We show real-time acquisition and processing of data, obtain images of mechanical activity while scanning across a cell culture, and investigate sub-second fluctuations of the piconewton forces exerted by macrophage podosomes. We also demonstrate force imaging of beating neonatal cardiomyocytes at 100 fps which reveals mechanical aspects of spontaneous oscillatory contraction waves in between the main contraction cycles. These examples illustrate the wider potential of our technique for monitoring cellular forces with high throughput and excellent temporal resolution.

The high-altitude missile and other special application occasions have requirements on image storage system, such as small size, high storage speed, low temperature resistance, etc. Commonly used image storage system in the market cannot meet such requirement. In the paper, real-time image storage system solutions on missile based on FPGA should be proposed. The system mainly consists of acquisition module and memory reading module. The whole system adopts FPGA as main control chip for mainly completing real-time decoding and acquisition on one path of PAL format video images, reading and writing of NandFlash chipset, erasure, bad block management and so on. The solution has passed various environmental tests with stable performance, large data storage capacity and easy expansion, which has been used in engineering practice.

From the perspective of multivariate intelligences theory innovation in college sports, the innovation of gymnastic specialty tennis teaching system is essential. Gymnastic specialty tennis teaching system should at least include teaching philosophy, teaching objectives, teaching content, teaching methods, teaching evaluation of five parts. The alteration of the teaching concept should attach much importance on the teaching democracy, personalized, and diversified teaching so as to boost comprehensive development of students. Meantime, the teaching should pay attention to cultivate the basic knowledge and basic skills of students, and improve students' health, the pursuit of sustainability and practicality. All of these will meet the objective which based on the needs of expansion body and multivariate intelligences in both training objectives and the tennis teaching process, in order to prepare for the part, basic part and the end part of the contents. All in all, all these will advance the overall development of students and combining with the theory of multivariate intelligence, further concluding the intelligence into the tennis teaching method.
