Donghua University Shanghai 200051he totally coded method (TCM) reveals the same objective law which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm it is more efficient because figure searching is no longer necessary. The code-series (CS) which are organized from node association table have the holoinformation nature so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.

A case study on the simulation of a local area network (LAN) that has been used at Vrije Universiteit Brissel (VUB) and the University of Bern to illustrate evolution of object-oriented programs, is reported. The study is intended to illustrate modeling support for software evolution. The case consists of an initial version of the simulation program and a series of changes in the specification that require it to evolve. The evolution of the program corresponds to a series of four consecutive requirements at the level of the LAN, which must be incorporated into the simulation program.

This paper contributes to the characterization of synchronous models of distributed computing using topological techniques. We consider a generic synchronous model with send-omission failures and use a topological structure corresponding to a bounded number of rounds of the model. We observe some nice properties of the structure and derive from these properties necessary and sufficient conditions to solve consensus in this model.

In this paper, the performance of turbo coded signals are investigated over Wireless Local Loop (WLL) environment with no side information on the phase noise and no channel state information (CSI). We assume that the transmitter and the receiver are point-to-point microwave links, separated by WLL which is modelled as 1+Dn/Partial Response Microwave Channel (PMRC) with realizable and practical medium parameters. Here, the combined effects of the nonideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered, each modelled by the Rayleigh and Tikhonov distributions respectively. As an example, the jitter performance of turbo coded signals are evaluated over 1+D/PRMC with effective signal-to-noise ratio in the carrier tracking loop, fading parameter, iteration number and frame data block size. The numerical results clearly demonstrate the error performance degradation due to both amplitude fading and phase noise process.

As concurrent software systems become larger, the interaction of their components is becoming more complex. This interaction may limit reuse, making it difficult to validate design and correctness and perhaps forcing reengineering of these systems in order to meet future requirements. In order to reduce this complexity and to build stable and adaptable concurrent software systems, we present an approach that emphasizes the separation of interaction components from the functional components.
