In order to improve the ability of users to share data within and across organizations, enterprises can move their data from user-managed devices to data centers accessible via cloud computing services. Such a transition in data storage, access, and management raises technical issues that are not addressed by current operating system, tagging, and configuration and control management technologies. In this paper we describe the notion of a cloud control environment in which cloud services automatically enforce multi-schema-based rules on the organization and manipulation of data objects.

Over the past decade, withthe increasing applications of wireless sensor networks, coordination of a group of mobile robots, autonomous vehicle formation and so on, various cooperative control problems such as consensus, flocking, and formation of multi-agent systems have attracted intensive attention. In this talk, we will describe a framework for handling various control problems for a multi-agent system. this framework will be called the cooperated output regulation problem. the core of this framework includes the establishment of the concepts of the distributed observer, and the distributed internal model. On one hand, we will show that this framework will set a stage for solving the asymptotic tracking and disturbance rejection problem in an uncertain multi-agent system via a distributed control approach. On the other hand, we will show that this framework contains many control problems of multi-agent systems such as consensus, synchronization, and formation as special cases, thus leading to a unified solution to several different control problems of multi-agent systems.

A multiple optimization algorithm, the Cultural Algorithm based on Particle Swarm Optimization (CAPSO) was applied to flight control law clearance. the algorithm provides a more accurate performance in function optimization when compared withthe traditional Particle Swarm Optimization (PSO). A short-period of longitudinal flight control system for a certain aircraft was designed before the validation. Two representative linear criterions were considered. the results indicate that the proposed algorithm provides an effective approach in search for worst combinations of parametric model uncertainties during process of flight clearance.
In this paper we present the design of our wireless mesh network testbed (CentMesh), which facilitates experimentation as a service. CentMesh differs from other testbeds in terms of its modular, flexible and extensibl...

An adaptive trajectory tracking method based on the kinematics model is proposed in this paper to solve the non-holonomic restriction problem of trajectory tracking of the wheeled mobile robot. After analyzing the course statement of the trajectory tracking control, the idea of the artificial field is introduced to improve the effect of the trajectory tracking, which takes the posture error of the robot into account to navigate the mobile robot. Withthe analysis of the controller's uniformly asymptotically stability and the simulations in MATLAB, the controller is proven to be practical and effective.

To solve the problem of traditional stream ciphers can not transmit through the public channel and the construction of high-strength cipher key generator, the paper presents the minimum power clock function driven by a parallel clock-control sequence and chaotic cascade function made of multiple Logistic function, which are used to built the self-reference model and chaotic module; it designs an adapt controller independent of the key generator and encrypt module, achieve controlling encryption and transmission process by multi-threaded code; it makes a high-strength key generator with sure differential transformation and pseudo-random horizontal level disturbance wheel key method of AES and S-box of Camellia, which makes the sub-key and the key generator's internal station become vogue and uncertain within controlled area that does not depend on the secret channel, the model achieves an exponential growth in the key space and the same application scope of traditional stream cipher model. the new protocol model features can be seen under the actual operation of modifying RC4 and real-time RC5 algorithm.

As an emerging portable service platform, OSGi is now taking a more and more important role in Ubiquitous computing environment. As a module management framework, OSGi provides the functions of dynamic loading and unloading software modules at runtime. But its use is limited because it is centralized and single programming language supported. In this paper we present LIR-OSGi, an extended framework of OSGi, which is designed to add the distribution and programming language independence to OSGi. Meanwhile it is easy to use for developers because of the transparence of service invocation and automation of distribution. Not like OSGi which can be applied only on the Java platform, LIR-OSGi makes programs which may be written in different programming languages be able to call each other transparently so that it can be applied in many different platforms such as DotNet Framework and so on. this brings much convenience to the program development in a distributed and heterogeneous environment.

A multi-input/multi-output (MIMO) furnace control system based on the PID control and the fuzzy radical basis functions neural network(FRBFNN) control is presented, in this paper. In addition, the structure models and relative learning algorithms of the FRBFNN controller are gived. At last, simulation and experiment results based on an application of the MIMO furnace control system are provided to show that FRBFNN-control system has more robustness than the PIDcontrol system especially in reducing noise and overcoming non linearities.
