Today, the presence of disturbing loads in low, medium and also directly in high voltage networks is producing a growing presence of harmonics and unbalance in transmission levels. Economic reasons difficult the installation of harmonic measurement devices in all the buses of the system. Instead, it would be possible to install harmonic measurement equipment in selected buses, in a fraction of ...

In this paper, we report our experiences and findings on the design of a fault-tolerant bus architecture comprised of two COTS buses, the IEEE 1394 and the I2C. This fault-tolerant bus is the backbone system bus for the avionics architecture of the X2000 program at the Jet Propulsion Laboratory. COTS buses are attractive because of the availability of low cost commercial products. However, they...

There is significant confusion in the space industry today over the terms used to describe satellite bus architectures. Terms such as “standard bus” (or “common bus”), “modular bus” and “plug-and-play bus” are often used with little understanding of what the terms actually mean, and even less understanding of what the differences in these space architectures mean. It may seem that these terms a...

Research Needs: Greenhouse gas (GHG) emissions from the transportation sector account for about 27% of the total GHG emissions in the United States. Due to increased travel demand and limited improvement in fuel efficiency, the GHG emissions from transportation have increased by 16% since 1990 (USEPA, 2015). About 80% of transit buses are currently powered by diesel engines, which are a primary...

Various augmenting mechanisms have been proposed to enhance the communication e ciency of mesh-connected computers (MCC's). One major approach is to add noncon gurable buses for improved broadcasting. A typical example is the mesh-connected computer with multiple buses (MMB). In this paper, we propose a new class of generalized MMB's, the improved generalized MMB's (IMMB's). Each processor in a...

This paper shows an effective partitioning of static global row/column buses for tightly coupled 2D mesh-connected small processor arrays (“mesh”, for short). With additional O(n/m (n/m + log m)) time slowdown, it enables the mesh of size m×m with static row/column buses to simulate the mesh of the larger size n×n with reconfigurable row/column buses (m ≤ n). This means that if a problem can be...

INTRODUCTION Considerable progress has been made in recent years in improving health and safety at work. For many people work does not take place in a fixed location but involves a large number of tasks associated with the control of a vehicle and exposed to all the hazards of a heavily trafficked environment. For those who drive lorries and buses there has been a deterioration over the last 20...
