In this paper we detail techniques that can be used to analyze and attack an AES implementation on an FPGA from the primary (i.e., external) side of a switched-mode power supply. Our attack only requires measurements of the duty cycle of the power supply, and then increases the signal-to-noise ratio (SNR) though averaging, deconvolution and wavelet based detrending. The result is an exploitable...

Power Management DesignLine (03/16/2005 2:58 PM EST) The power supply is the backbone of any electronic device, and its performance is especially critical in the growing mobile consumer market, where not only accuracy but also power efficiency is crucial, which explains why switching supply circuits have enjoyed such popularity. For the safety, performance, and feedback control of these switch...

In this thesis we seek to develop smaller, less expensive, and more efficient power electronics. We also investigate emerging applications where the proper implementation of these new types of power converters can have a significant impact on the overall system performance. We have developed a new two-stage dc-dc converter architecture suitable for low-voltage CMOS power delivery. The architect...

The sinewave generators based the switched-capacitor (SC) technologies are implemented in transistor level. This analogue sinewave generator consists of two parts: an approximate sinewave generator and a filter. The structure of this generator is robust and easily-controlled, in which an approximate sinewave is firstly generated based on SC circuits and then filter the harmonics. The main advan...

primary endpoint, but also the secondary endpoints that should corroborate the primary endpoint, will stand. This approach is based on the Prentice principle, which states that a result has a higher probability of being truly positive if other related endpoints are also positive 1. An advantage in progression-free survival (pfs) has more chance of being true if a statistically significant advan...

In this paper, synchronization control of switched linearly coupled delayed neural networks is investigated by using the Lyapunov functional method, synchronization manifold and linear matrix inequality (LMI) approach. A sufficient condition is derived to ensure the global synchronization of switched linearly coupled complex neural networks, which are controlled by some designed controllers. co...

Prominent harmonics in IT offices are essentially due to the presence of SMPS in computers large numbers. In a three-phase, fourwire system, current harmonics leads to flow zero sequence current in neutral conductor, increased losses in motors, false tripping of circuit breakers. In this paper, VSI is designed as a compensator based instantaneous reactive power theory. And is used to mitigate t...

Switched Ethernet has been considered as a promising network technology for real-time communications required by process control, factory automation and other real-time applications. The switched Ethernet has many features for real-time communications such as providing a large amount of bandwidth, micro-segmentation of traffic, and full-duplex links, but to provide the hard real-time communicat...

The use and potential benefits of self-adaptive mutation operators are well-known within evolutionary computing. In this paper we begin by examining the use of self-adaptive mutation in Learning Classifier Systems. We implement the operator in the simple ZCS classifier and examine its performance in two maze environments. It is shown that, although no significant increase in performance is seen...

The great interest raised by the advantages of using Ethernet technology to support real-time communications has led to various proposals in the literature, involving both Shared and Switched Ethernet, to obtain predictable behavior. However, to reduce application-to-application transfer time, latency within the end-nodes has to be addressed too. This paper illustrates a solution to improve the...
