Prospective designs of microwave power amplifiers for on-board equipment service systems are considered, in which the problem minimizing area occupied by them on a thermally stabilized plate spacecraft is solved. Microwave provide good heat dissipation and require degree redundancy. Each included redundant amplifier made boards located perpendicular to heat-stabilized fixed one or both sides. T...

In Automonous Decentralized Systems (ADS), there is a high degree of uncertainty, especially in global state information and the performance and reliability of various resoufces. W e model a distributed computer system of local and shared global servers, each of which can process jobs. The local servers insure a degree of autonomy and the global servers provide added computational power and red...

In order to improve the ability of gradual learning on the training set gotten in batches of Naive Bayesian classifier, an incremental Naïve Bayesian learning algorithm is improved with the research on the existing incremental Naïve Bayesian learning algorithms. Aiming at the problems with the existing incremental amending sample selection strategy, the paper introduced the concept of sample Cl...

One of the main issues in securing multicast communication is the source authentication service. In this work we address the multicast stream authentication problem when the communication channel is under the control of an opponent who can drop, reorder or inject data. In such a network model, packet overhead, computing efficiency and robustness against packet loss are important parameters to b...

Mobile manipulators are of high interest to industry because of the increased flexibility and effectiveness they offer. The combination and coordination of the mobility provided by a mobile platform and of the manipulation capabilities provided by a robot arm leads to complex analytical problems for research. These problems can be studied very well on the KUKA youBot, a mobile manipulator desig...

Due to the manufacturing process, the shrinking of electronic devices will inevitably introduce a growing number of defects and even make these devices more sensitive to external influences. It is, therefore, likely that the emerging nanometer-scale devices will eventually suffer from more errors than classical silicon devices in large scale integrated circuits. In order to make systems based o...

With the increase of power transaction business, traditional data interaction models cannot fully meet needs interaction. The model conforming to architecture plays an important role. Data requirements Chinese electricity market business are analyzed, and specific method description is given in IEC-61970 protocol standard. Also a common information (CIM) for trans-action built that conforms arc...

Finding motifs in biological sequences is one of the most intriguing problems for string algorithms designers due to, on the one hand, the numerous applications of this problem in molecular biology and, on the other hand, the challenging aspects of the computational problem. Indeed, when dealing with biological sequences it is necessary to work with approximations (that is, to identify fragment...

The manipulator with a large degree of redundancy is useful for realizing multiple tasks such as maneuvering the robotic arms in the constrained workspace, e.g. the task of maneuvering the end-effector of the manipulator along a pre-specified path into a window. This paper presents an online technique based on a posture generation rule to compute a null-space joint velocity vector in a singular...
