Cloud computing is based on cloud storage. Cloud storage through a variety of technical storage device abstraction into virtual storage resource pool. Compared with the traditional way of storage, it has the scalability and high performance, low cost and other advantages. Different cloud storage systems have different technical architecture and characteristics. From the perspective of metadata if there is a center node, with and without the typical cloud storage system to do a simple introduction and mainly for open source without Gluster center system are analyzed in focus. © (2014) Trans Tech Publications, Switzerland.

SuperSpeed bus, also known as USB3.0 bus or SuperSpeed USB bus, is the newest USB bus technology. This paper presents an innovative DMA transfer method called Multi-thread Chain DMA for SuperSpeed bus video data transmissions. The maximum 5Gbps giant data rate of SuperSpeed bus demands a high speed and high reliability DMA method. However, traditional DMA method can not achieve this required data rate due to its separate data transmission and reception. Unlike traditional DMA method, utilizing a novel designed mechanism, Multi-thread Chain DMA transfer method transmits and receives data concurrently, achieves SuperSpeed data rate and guarantees no data loss. Furthermore, one communication protocol for SuperSpeed video transmission is designed and implemented to comply with USB Video Class (UVC) standard. The field trial has demonstrated Multi-thread Chain DMA transfer method and SuperSpeed video communication protocol in the article are feasible and rich in value of research. © (2014) Trans Tech Publications, Switzerland.

As a result of linear matrix inequality (LMI) and its good nature of mathematics as well as the breakthrough of solution method, many control problems can be transformed into a standard LMI problem to solve. Linear matrix inequality has received widely attention and applications in control system analysis and design. This paper introduces some of the basic content of LMI, such as the general description, the relevant algorithms and software. The controller will be designed using LMI such that the closed-loop system is asymptotically stable, and simulation will be given using Matlab. Finally, the population model will be given and analyzed. © (2014) Trans Tech Publications, Switzerland.

B4C-coated diamond (diamond@B4C) particles are used to improve the interfacial bonding and thermal properties of diamond/Cu composites. Scanning electron microscopy, x-ray diffraction, and x-ray photoelectron spectroscopy were applied to characterize the formed B 4C coating on diamond particles. It is found that the B4C coating strongly improves the interfacial bonding between the Cu matrix and diamond particles. The resulting diamond@B4C/Cu composites show high thermal conductivity of 665 W/mK and low coefficient of thermal expansion of 7.5 × 10-6/K at 60% diamond volume fraction, which are significantly superior to those of the composites with uncoated diamond particles. The experimental thermal conductivity is also theoretically analyzed to account for the thermal resistance at the diamond@B4C-Cu interface boundary. © 2013 ASM International.

The control theory has widely application in many fields such as industrial and agricultural. A class of see-saw system model will be studied in this paper. Using the theory of pole assignment, we will design the state feedback controller, such that the closed-loop system is asymptotically stable. At the same time, using the tool of MATLAB, the model of closed see-saw system will be simulated and analyzed. It reveals the state regularity of see-saw system. © (2014) Trans Tech Publications, Switzerland.
