We present a fault-tolerant routing algorithm which requires no virtual channels for mesh networks. Our method employs the concepts of fault rings and fault chains, which were previously used with virtual channels, to facilitate fault-tolerant routing. Typically, the number of faults that can be tolerated in a mesh without virtual channels is very small, or the number of nonfaulty nodes that mu...

Reports and Memoranda No. 332±* t February, z96z Summary. Apparatus is described for the measurement of shock attenuation.in channels of several configurations. A circular-bore channel, a square-bore channel and converging and diverging channels have been investigated. Measurements of hot-flow duration and wall pressure variations in the shock tube have also been made. It is concluded that conv...

Functional studies have shown that the sphingolipid ceramide, self-assembles in phospholipid membranes to form large channels capable of allowing proteins to cross the membrane. Here these channels are visualized by negative stain transmission electron microscopy. The images contain features consistent with stain-filled pores having a roughly circular profile. There is no indication of tilt, an...

We derive the two-user capacity region with and without common information for a Gaussian broadcast channel with intersymbol interference, assuming colored Gaussian noise and an input power constraint. The proof is achieved by rst deening a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for p...

Introduction: A new modelling method suited to the dual circular polarised 2x2 (MIMO) channel applicable to land mobile satellite (LMS) communications in line of sight cases is presented. In this scenario, it is necessary to apply correlated fading to the co-polarised and cross-polarised channels separately in order to model the evident polarization multiplexing in such channels found from meas...

We propose a technique to avoid deadlocks in a system of communicating processes. Our network model is very general. It supports dynamic process and channel creation and the ability to send channel endpoints over channels, thereby allowing arbitrary dynamically configured networks. Deadlocks happen in such networks if there is a cycle created by a set of channels, and processes along the cycle ...

The microchannel heat sink has been recognized as an excellent solution in high-density flux devices for its high efficiency removal with limited spaces; however, the most effective structure of microchannels dissipation is still unknown. In this study, fluid flow and transfer high-temperature wavy various shaped fins, including bare channel, channel circular, square, diamond-shaped are numeric...

The effects of flufenamic acid were investigated on slow waves, follower potentials and pacemaker potentials recorded respectively from circular smooth muscle cells, longitudinal smooth muscle cells and interstitial cells of Cajal distributed in the myenteric layers (ICC-MY) of the guinea-pig stomach antrum. Flufenamic acid (>10(-5) M) inhibited the amplitude and rate of rise of the upstroke ph...
