The paper will present the application of artificial neural network of Support Vector Machine (SVM) type to the fault location in analog electrical filter. The recognition of fault is based on the measurements of the accessible terminal voltage and current of the network, transformed according to the proposed procedure. The SVM network is applied as the recognizing system and as the classifier....

Kron reduction is used to simplify the analysis of multi-machine power systems under certain steady state assumptions that underly the usage of phasors. Using ideas from behavioral system theory, we show how to perform Kron reduction for a class of electrical networks without steady state assumptions. The reduced models can thus be used to analyze the transient as well as the steady state behav...

This paper describes a computer model for calculating the surge propagation in the winding of electrical machines. The model considers the winding as a combination of a multiconductor transmission line and a network of lumped parameters. The frequency dependence of the winding electrical parameters are calculated and incorporated into the analysis by means of Foster and Cauer circuits. Finally,...

Throughout the ages people have been working in research institutes and industries in machine automation so as to have less involvement of operator in machine operations. In the development of automation controllers the trend has been to move towards soft controllers so as to provide better control, more flexibility and more reliability with intelligent diagnostics of machine faults. So industr...

Yuchi Liu, Yao Xiao Department of Electrical Engineering Stanford University Stanford, CA [email protected] , [email protected] Abstract—Recognizing circuit sketch is very useful for electrical engineers. In this project, we use topology based segmentation method to segment circuit sketch, and classify each component using the Fourier descriptors as feature vector for Support Vector Mach...

The purpose of this study was to compare one-repetition maximum (1-RM) and muscle activity in three chest-press exercises with different stability requirements (Smith machine, barbell, and dumbbells). Twelve healthy, resistance-trained males (age 22.7 ± 1.7 years, body mass 78.6 ± 7.6 kg, stature 1.80 ± 0.06 m) were tested for 1-RM of the three chest-press exercises in counterbalanced order wit...

This paper investigates the electrical machine, which is one of the important parts in the Free Piston Energy Converter (FPEC). In the previous work it was found that one of the best candidate suitable for the FPEC is a Transverse Flux Machine (TFM) due to the very tough requirements on the electrical machine such as a low weight of the translator (movable part in the machine).This paper presen...

In this paper we demonstrate the first real-world cloning attack on a commercial PUF-based RFID tag. The examined commercial PUFs can be attacked by measuring only 4 protocol executions, which takes less than 200 ms. Using a RFID smartcard emulator, it is then possible to impersonate, i.e., “clone” the PUF. While attacking the 4-way PUF used by these tags can be done using traditional machine l...

Ensuring reliability as the electrical grid morphs into the “smart grid” will require innovations in how we assess the state of the grid, for the purpose of proactive maintenance, rather than reactive maintenance – in the future, we will not only react to failures, but also try to anticipate and avoid them using predictive modeling (machine learning) techniques. To help in meeting this challeng...

At present, there are many faults conditioning system for electrical or mechanical machines. In most of the cases, these are easily built as data for training can be collected from one machine
