As cellular packet data services become widely deployed by the rollout of the networks such as General Packet Radio Service (GPRS) and 3G cellular networks, packet-switched voice service such as voice over IP (VoIP) can soon be expected to be offered as an alternative to circuit-switched voice service. While circuit-switched voice offers better quality, packet-switched voice offers better resou...

Tolerances of electronic circuit parameters play an important role in our judgement of circuit functionality. They must be considered both at the circuit design and testing stages. This paper discusses a problem of tolerances in a symbolic network analysis. Using topological analysis combined with operations on discrete random variables, we can predict behavior of a circuit with toleranced para...

This paper proposes a new high-speed network architecture DBTN(Dynamic burst transfer time-slot-base network), which is based on circuit-switched network technology. A routing tag is attached to a burst at an ingress edge node and the burst is selfrouted in a DBTN network by creating a circuit dynamically. The routing tag, which is called time-slots-relay, is a series of link identifiers to the...

In this paper we discusses solution of Linear Programming problems through neural network. Without having location restriction this network uses only simple hardware. Here we proved to be completely stable to exact solution without any multipliers. Moreover using this network we can solved linear programming problems and its dual simultaneously. These linear programming problems uses circuit im...

It is a difficult problem that using cellular neural network to make up of analog signal processing circuit. This paper presented the architecture of new cellular neural network SCCNN for analog signal processing circuits, designed the neural cell circuit, and developed the evolutionary design method of the SCCNN based on selfadapting genetic algorithm. In the architecture of new cellular neura...

We develop a method for non-trivially restricting fanout in a circuit. We study the complexity of the Circuit Value problem and a new problem, Network Stability, when fanout is limited. This leads to new classes of problems within P. We conjecture that the new classes are different from P and incomparable to JVC. One of these classes, CC, contains several natural complete problems, including Ci...

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
