Digital storage oscilloscope (DSO) is, with applied far going, high sampling frequency and measuring accuracy, a common testing instrument in signal acquisition and processing. While many DSOs are used together to measure multi-channels of signals, there exist some problems in synchronous comparing, acquisition, storage and plots of different signals. In order to solve these problems, the features...
Any activity in a computer-supported cooperative working environment produces a set of traces. In a collaborative working context, such traces may be very voluminous and heterogeneous. They reflect all the interactive actions among the actors themselves and between the actors and the system. This paper examines what is required to exploit traces in the context of a collaborative working environment...
In paper[1], Yang proposed a dynamic auction algorithm under price rigidities for item allocation. The problem under consideration is a very difficult one in the sense that it is NP-Complete. The algorithm is based on a specific allocation rule and a rationing system of Rn. In this paper, we discuss a practical implementation of the algorithm and present a computer program using binary operations...
The importance and effect of artillery servo system in all kinds of automated weapons are narrated. The requirements of type approval test for artillery servo system are introduced. A new kind of distributed measurement and control system based on CAN bus is put forward, which is used in type approval test of artillery servo system to accomplish four measurement and control tasks: driving servo system...
With the popularization of computers and social development, it is become more and more common the personal remote office and electronic office. The question is becoming that how to synchronization of large amounts of files between multiple computers. In this paper, the mechanisms of metadata is used to directory synchronization and control file version. According one of the properties of the cloud...
Personal high performance computer (PHPC) requires lower cost and high performance. The Teraflops PHPC systems with special accelerator units like GPGPU have been presented, but they have difficulties in programming, compatibility and applicability. In this paper, we present HPP-PHPC, a hybrid architecture of heterogeneous processors connected by non-coherent off-chip system bus. The performance of...
The layout problem of weighted circles is a class of layout optimization problems with behavior constraints. Aiming at this NP-hard problem, this paper puts forward a fast heuristic ant colony approach(FHACA). This approach obtains the heuristic information from weighted matrix and uses it to construct the better ants and design parameters of ant colony optimization. The layout schemes of some ants...
