چکیده
Current oo-line electronic cash systems are often too complex to implement. In this paper, we propose an eecient oo-line digital cash payment system that still maintains basic security features such as double-spending detection and client anonymity. Using a one-way hash function chain, our method veriies the clients to perform one single online computation (response) for the whole payment.

A Novel Algorithm for Digital Distance Relaying
Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...

AE is a serious medical condition in which the immune system attacks the brain, impairing function. With rapid diagnosis and appropriate treatment, many patients recover most or all functions. However, not all patients experience full recovery; with approximately 6% mortality and other patients who never regain significant brain and/or bodily functions. Autoimmune encephalitis can pro...
متن کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملDigital Distance Relaying
Increasing interest is being shown in the use of microprocessor for protection, switching and data acquisition required in modern high voltage substations. One of the most difficult functions to fulfill is that of transmission line distance protection employing samples of the voltage and current waveform taken from high voltage transducer equipment at the usual relaying point. This paper examin...
