This paper presents the design of a hybrid excited flux switching Vernier machine. machine is designed to serve in renewable energy conversion applications, such as wind turbine generator, or tidal generator. After introducing this original structure, based on finite element models conducted. The specifications correspond relatively low power direct drive applications. rated set 10 kW, with spe...

The security of many cryptographic schemes and protocols rests on the conjectured computational intractability of the discrete logarithm problem in some group 〈g〉 of prime order. Such schemes and protocols require domain parameters that specify 〈g〉 and a specific generator g. In this paper we consider the problem of computing information on the domain parameters from public keys selected unifor...
