Reed-Solomon code or RS code is widely used for error corrections of data in transmission and storages. However, it is thought of as insecure for direct implementation in code-based cryptography due to plaintext-known attacks. In recent years, McEliece cryptosystem with enhanced public key security by generalized RS code and Goppa code are discussed for hardware implementation. In this work, from...
This A novel high frequency high voltage (HV) generator with silicon carbide (SiC) power semiconductor devices is proposed in this paper to achieve high energy efficiency, fast HV pulse speed and compact size advantages. The electrical and HV insulation design and analysis high frequency HV transformer and voltage multiplier circuit based on 1.2kV SiC Schottky diode are discussed in details. 1.2kV...
PSS4B stabilizer is a multi-band stabilizer received attention in recent years. The effectiveness of such a stabilizer depends on a number of factors, among them how stabilizer parameters are tuned playing a key role. In this case study, two common parameter tuning methods, the ideal phase curve method and the residue method, are used to determine the parameters of a PSS4B stabilizer and a PSS1A stabilizer...
The tie-line power oscillation of two-area interconnected system after power impact is derived strictly. The dynamic equations before the disturbance and after the disturbance are constructed and the variation of the tie-line power is derived. Based on the theory of distribution of impact power in power systems, the tie-line power of two-area system after power impact is derived. The expressions of...
There are many uncertainties in image segmentation, which should be handled by theories and methods with uncertainty. Cloud model is a kind of effective method to handle uncertainty, which considers fuzziness, randomness and the connection of them. Image segmentation based on one-dimensional cloud model processes the one-dimensional grayscale histogram, and segments images using one-dimensional cloud...
This paper addresses the decision trees induction with uncertain data. In other words, it presents a novel method, called uncertain decision trees (UDT) to handle the uncertainty during the process of inducing decision trees. Here, uncertainty is depicted via cloud model theory, a quantitative-qualitative transforming model with uncertainty, which can well integrate the fuzziness and randomness of...
In this paper, taking the doubly fed induction generator (DFIG) wind turbine as the research object, an electromagnetic transient simulation model is established in PSCAD/EMTDC simulation environment to analyze the active power and reactive power regulation capacity of DFIG wind turbine. Under different wind speed, maximum power point tracing (MPPT) control is implemented to ensure the optimum active...
A new method for transmission line expansion planning using the branch and bound method is presented in this paper. Some candidate alternatives should be chosen in the beginning of planning procedures. To obtain the economical optimal scheme, all of these candidate alternatives should be considered, so this paper gave a concept of the planning set for describing all elements such as the transmission...
This paper presents a marine generator control system which BDFM control winding side is controlled by commercial converter. Two problems of the commercial converter in control system is solved. One is the common commercial converterpsilas output voltage and frequency at constant V/F curve, the other is it canpsilat feedback energy to AC power. Based on generator voltage and frequency loop , we discuss...
