In this paper the Space Vector Control Scheme is implemented for a Wind Energy System using Three Level Impedance Source Inverter (ZSI). The wind energy system uses a Self Excited Induction generator (SEIG) which is the most emerging application in the field of Wind Energy Conversion System (WECS). The proposed system is modelled with a generator-side Diode Bridge Rectifier and a Stand-Alone si...

The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...

The Shrinking Generator, presented at Crypto'93, is a LFSR-based pseudorandom generator suitable for the implementation of additive stream ciphers. It is particularly simple and has attractive security properties. (The reader is referred to [1] for the definition of the generator and its properties). Although the algorithm was originally intended for hardware implementation, here we will focus ...

Steganography over real-time streaming media is a novel and promising research subject. This paper performs steganography over a typical streaming media, Voice over IP (VoIP), and suggests a new covert communication scheme for interactive secret messages. To resist the statistical detection, a sophisticated compounded pseudorandom sequence, produced by a compounded pseudorandom number generator...

Testing has its obvious place in any software development project cycle and is the most important technique to verify correctness of software implementations. This Master’s thesis will explain several techniques used today to test software systems, followed by a presentation of how an automatic test generator ordered by Ericsson Radio Systems has been designed and implemented as a part of this ...

To understand the behaviour of search methods (including GAs), it is useful to understand the nature of the landscapes they search. What makes a landscape complex to search? Since there are an infinite number of landscapes, with an infinite number of characteristics, this is a difficult question. Therefore, it is interesting to consider parameterised landscape generators, if the parameters they...

Background: Hot lab is a specially designed room in a nuclear medicine hospital where the radiopharmaceuticals are delivered, stored and prepared for dispensing. 99Mo/99mTc-generator is the major source in the hot lab used for various medical imaging. It is important to maintain a standard for hot lab procedures to optimize the patient care and minimize radiation exposure to all nuclear medicin...
