This paper describes the development of a permanent magnet generator for small scale wind turbines. The generator has been designed for ease of manufacture so that it can be made by small mechanical engineering companies with limited electrical engineering knowledge. The generator has also been designed to have no cogging torque so that it can be used with all horizontal and vertical axis turbi...

Nonlinear congruential pseudorandom number generators based on inversions have recently been introduced and analyzed. These generators do not show the lattice structure of the widely used linear congruential method. In the present paper it is proved that the points formed by d consecutive pseudorandom numbers of an inversive congruential generator with prime modulus possess an even stronger pro...

A compact repetitive Marx generator and a High Power Microwave (HPM) source based on a matched reflex triode has been developed and tested. The Marx generator rated at 1 kJ, 300 kV, 12 kA, 10 Hz, is suitable to drive the reflex triode directly. Bipolar charging of the Marx generator has been used to get lower system inductance and consequently faster output rise time with relatively low chargin...

-This paper examines the impact of the network modification produced by the replacement of an existing conventional generator with a high voltage directly connected generator on the adequacy of existing circuit breakers distributed throughout a high voltage transmission network. The significance of generator design changes is assessed by comparing the critical fault types producing maximal circ...

For any finitely generated group Y, u(Y) denotes the Turing degree of the word problem of Y. Let G be any non-Abelian 2-generator group and B an infinite group generated by k > 1 elements. We prove that if t is any Turing degree with t > l.u.b.(co(G), u(ß)} then the unrestricted wreath product W = GWrB has a (k -f l)-generator subgroup H with u(H) = r. If B is also periodic, then W has a /c-gen...

Convolutional codes over rings have been motivated by phase-modulated signals. Some structural properties of the generator matrices of such codes are presented. Successively stronger notions of invertibility of generator matrices are studied, and a new condition for a convolutional code over a ring to be systematic is given and shown to be equivalent to a condition given by Massey and Mittelhol...

In this paper, we study the maintenance of frequent patterns in the context of the generator representation. The generator representation is a concise and lossless representation of frequent patterns. We effectively maintain the generator representation by systematically expanding its Negative Generator Border. According to our literature review, no prior work has studied the maintenance of the...

Sciences (ESFS) staff has conducted a limited, exploratory exercise to demonstrate the feasibility of using Global Positioning System (GPS) technology to distinguish indoor and outdoor environments, with the intent of shutting down portable generator operation when a generator is used indoors. Through a series of experiments, ESFS staff demonstrated that a modified, off-the-shelf, commercially ...

We introduce FlexibleSUSY, a Mathematica and C++ package, which generates a fast, precise C++ spectrum generator for any SUSY model specified by the user. The generated code is designed with both speed and modularity in mind, making it easy to adapt and extend with new features. The model is specified by supplying the superpotential, gauge structure and particle content in a SARAH model file; s...
