Near Future

Embedded platforms are projected to integrate hundreds of cores in the near future, and expanding the interconnection network remains a key challenge. We propose SNet, a new Scalable NETwork paradigm that extends the NoCs area to include a software/hardware dynamic routing mechanism. To design routing pathways among communicating processes, it uses a distributed, adaptive, non-supervised routing method based on the ACO algorithm (Ant Colony Optimization). A small footprint hardware unit called DMC speeds up data transfer (Direct Management of Communications). SNet has the benefit of being extremely versatile, allowing for the creation of a broad range of routing topologies to meet the needs of various applications. We provide the DMC module in this work and assess SNet performance by executing a large number of test cases.

Представлены подходы к повышению устойчивости функционирования информационно-телекоммуникационной сети, которые способствуют оптимизации процесса передачи данных среди обменников информации за счет повышения быстродействия и нахождения оптимального пути передачи данных. Отмечается, что сокращение времени обмена информацией между абонентами будет происходит по наиболее короткому пути и это должно существенно повлиять на качество информации,ее важность и необходимость при ведении боевых действий в условиях радиоэлектронного противодействия противника. Various approaches to improving the stability of telecommunications networks, which lead to optimizing the data transfer process by increasing the speed and finding the most optimal data transfer path, are presented. It is noted that the reduction of the data exchange time between subscribers will occur along the shortest path, which will significantly affect the quality of information, its importance, and the need for conducting combat operations in the condition of electronic counteraction of the enemy.

Delay Tolerant

Delay Tolerant Networks (DTN) has been widely used in challenge networks as an emerging network architecture. Among all studies , routing mechanism is the key problem in DTN. Because of high latency and low data rate, the traditional network routing algorithm can not apply to DTN. This paper proposed a DTN routing mechanism based on area dipartition. The mechanism divided the space into several regions, and calculated the probability of occurrence of each node in each region to determine data transfer path according to the probability. Finally, the simulation results show that the mechanism can significantly enhance the message delivery probability and reduce the packet loss rate.

Electron crystallography is an emerging field for structure determination as evidenced by a number of membrane proteins that have been solved to near-atomic resolution. Advances in specimen preparation and in data acquisition with a 400kV microscope by computer controlled spot scanning mean that our ability to record electron image data will outstrip our capacity to analyze it. The computed fourier transform of these images must be processed in order to provide a direct measurement of amplitudes and phases needed for 3-D reconstruction.In anticipation of this processing bottleneck, we have written a program that incorporates a menu-and mouse-driven procedure for auto-indexing and refining the reciprocal lattice parameters in the computed transform from an image of a crystal. It is linked to subsequent steps of image processing by a system of data bases and spawned child processes; data transfer between different program modules no longer requires manual data entry. The progress of the reciprocal lattice refinement is monitored visually and quantitatively. If desired, the processing is carried through the lattice distortion correction (unbending) steps automatically.

A drug information system (DARIS) has been created for handling reports on suspected drug reactions. The system is suitable for being run on desktop computers with a minimum of hardware requirements: 187 K read/write memory, flexible or hard disc drive and a thermal printer. The data base (DRUG) uses the QUERY and IMAGE programming capabilities for data entry and search. The data base to statistics link program (DBSTAT) enables data transfer from the data base into a file for statistical analysis and signalling suspected adverse drug reactions.The operational, medical and statistical aspects of the general population voluntary adverse drug reaction monitoring programme—recently initiated in the State of Kuwait—are described.

End To End

SKK Migas plans to apply end-to-end security based on Web Services Security (WS-Security) for Sistem Operasi Terpadu (SOT). However, there are no prototype or simulation results that can support the plan that has already been communicated to many parties. This paper proposes an experiment that performs PRODML data transfer using WS-Security by altering the WSDL to include encryption and digital signature. The experiment utilizes SoapUI, and successfully loaded PRODML WSDL that had been altered with WSP-Policy based on X.509 to transfer a SOAP message.
