Under unbalanced supply condition low order harmonics will appear at the input and output terminals of the PWM AC to DC converter. Based on the positive and negative sequence components, an unbalanced transfer matrix in terms of the input phase voltages is derived. An on-line method using a neural network (NN) is used to implement this transfer matrix. It is shown that by using an additional lo...

A block cipher is a bijective function that transforms a plaintext to a ciphertext. A block cipher is a principle component in a cryptosystem because the security of a cryptosystem depends on the security of a block cipher. A Feistel network is the most widely used method to construct a block cipher. This structure has a property such that it can transform a function to a bijective function. Bu...

We propose a novel architecture, a Combined Input-CrosspointOutput Buffered (CIXOB-k, where k is the size of the crosspoint buffer) Switch. CIXOB-k architecture provides 100% throughput under uniform and unbalanced traffic. It also provides timing relaxation and scalability. CIXOB-k is based on a switch with Combined Input-Crosspoint Buffering (CIXB-k) and round-robin arbitration. CIXB-k has a ...

This paper investigates the efficiency of unbalanced versus balanced multiwavelets in stereo correspondence matching. A multiwavelet transform is first applied to a pair of stereo images to decorrelate them into a number of subbands. Information in the approximation subbands of an unbalanced multiwavelet carries different spectral content of the input image while the balanced multiwavelet appro...

In this article, an improved space vector pulsewidth modulation strategy for matrix converter is proposed under unbalanced input voltages. First, to obtain the higher output voltage, two novel strategies based on linear superimposition principle are presented by modifying magnitude of reference voltage and current vectors. Second, in order evaluate performance strategy, harmonic characteristics...

The design of membrane-based Schottky planar diode frequency triplers to 1.9 THz is discussed. Both, balanced and unbalanced circuit designs are proposed and compared. The simulations show that with 2.5 to 3.5 mW of input power the balanced triplers can produce sufficient power to pump hot electron bolometer mixers. However, if the available input power is limited to 1 mW then the unbalanced de...

Reactive power in balanced and unbalanced lines constitutes the main problem that is examined in this article. We will describe a balanced line as a line with differential input and output signals. Unbalanced lines, such as the SWER scheme, have to cope with the reactive power problem. However, this problem does not exist in the one wire balanced B-Line scheme. In addition, various methods of g...
