In this paper, we present a new technique to improve the reliability of SRAMs used in space radiation environments. This technique deals with the SRAM power-bus monitoring by using Built-In Current Sensor (BICS) circuits that detect abnormal current dissipation in the memory power-bus. This abnormal current is the result of a single-event upset (SEU) in the memory and it is generated during the...

It gives a new type of multi-channel temperature acquisition system that is equipped with Samsung S3C2440 and combined the Can bus communications technology. This system implements the acquisition, management and displaying printing of the multi-channel temperature data on the industry site. According to the control information, it collects multi-channel temperature, then passes the temperature...

This paper presents a protocol proposal that makes Ethernet suitable for supporting modern real-time systems. Applications that could benefit from the proposed protocol are mainly those composed of heterogeneous distributed components, which are specified in terms of both hard and soft timing constraints. Indeed, using the proposed protocol, hard and soft real-time tasks can efficiently and pre...

As technology scales, increasing clock rates, decreasing interconnect pitch and the introduction of low-k dielectrics have made self-heating of the global interconnects an important issue in VLSI design. Further, high bus temperatures have had a negative impact on the delay and reliability of on-chip interconnects. Energy and thermal models are used to characterise the effects of self-heating o...

Abstract: The public transit system are essential services to the sustainability and livability of any city. Transit agencies are consistently trying to improve service reliability and attract passengers by applying various strategies. In this paper, we present an approach to mining the temporal behavior of the passengers in a public transportation system, which may help the transport operators...

Proposed Probabilistic Load Flow (PLF) approach, based on the method of cumulants, is used for bus voltage security assessment. The work accurately estimates the unknown probability distribution and density function of the involved complex random variables (CRV’s). With the help of these distributions a fast and accurate contingency ranking for security assessment is made possible. The advantag...

-----------------------------------------------------------ABSTRACT----------------------------------------------------------It is very important to maintain supply reliability under the deregulated environment. The transient stability problem is one of the major concerns in studies of planning and operation of power systems. Although the equalarea criterion method is useful in determining the ...

This paper presents a synchronized phasor measurement-based wide-area backup protection scheme which uses the magnitude of sequence voltages of buses at a system protection centre to identify the faulted bus closest to the fault and faulted line. The technique is tested for various faults including simultaneous faults in various systems with interconnections. The scheme is found to be accurate ...

This paper presents a multi-objective transmission expansion planning (TEP) framework. Rather than using the conventional deterministic reliability criterion, a risk component based on the probabilistic reliability criterion is incorporated into the TEP objectives. This risk component can capture the stochastic nature of power systems, such as load and wind power output variations, component av...

This paper presents a method in expansion planning of transmission systems using the AC optimal power flow (AC-OPF). The AC-OPF provides a more accurate picture of power flow in the network compared to the DC optimal power flow (DC-OPF) that is usually considered in the literature for transmission expansion planning (TEP). While the AC-OPF-based TEP is a mixed-integer nonlinear programming prob...
