Support Vector Machines in R

Karatzoglou, Alexandros, Meyer, David, Hornik, Kurt January 2005 (has links) (PDF)
Being among the most popular and efficient classification and regression methods currently available, implementations of support vector machines exist in almost every popular programming language. Currently four R packages contain SVM related software. The purpose of this paper is to present and compare these implementations.

Analysis and simulation of faults in squirrel cage motors

Stavrou, Andreas January 1994 (has links)
Condition based maintenance of electrical machines offers significant advantages for industry. A large part of the research effort in this area is directed towards the evaluation of fault conditions. This thesis is concerned with analysing and modelling faults in induction motors. A method for evaluating the performance of induction machines with static and dynamic eccentricity is developed, using harmonic analysis of the air gap permeance. Models able to simulate eccentricity are presented. The slip ring model equations are obtained and then used to obtain the commutator models transformed to a single reference frame. A variety of effects accompanying these fault conditions are analysed, for example variation of the eccentricity level due to unbalanced magnetic pull and the possibilities of additional vibration harmonics examined. Damping of eccentricity fields due to current redistribution, saturation and slotting are discussed. Some general steady state calculations are also presented which show that the performance of the machine need not be changed over the operating range, due to such a fault. The characteristics of combined static and dynamic eccentricity are examined and it is shown that the combined asymmetry generates additional harmonic components which are not related to those which occur when the two asymmetries take place in isolation. The development of a simulation model of machines with broken rotor bars, based on the variation in rotor parameters is presented. Experimental investigations focus mainly on observable differences in the torque transient characteristics, due to such a condition. The possibilities for using current monitoring to identify inter-turn short circuits are investigated.

Living machine

Guo, Hao January 2009 (has links)
"In terms of what they are capable of, it seems to me, when you have the distance narrowing between humans and machines in the sense that if we are becoming more machine-like, it's easier to see the machine as more human-like. I don't want to be overly dramatic about it, but I think more and more people wonder, is this living or are we just going through the motions? What's happening? Is everything being leached out of life? Are the whole texture and values and everything kind of draining away? Well, that would take many other lectures, but it's not so much the actual advance of the technology: If machines can be human, humans can be machines. The truly scary point is the narrowing of the distance between the two".In John Zerza’s talk ‘Against Technology’ at Stanford University, he observed that when you have the distance between humans and machines narrowing then in a sense we are becoming more machine-like, and it’s easier to see the machine as more human like. These views are similar to the views I have been considering for some time in my art practice.My research paper attempts to chart the relationship between my art practice and personal and global circumstances as an international student from Beijing studying at an art school in Melbourne.Living Machines also finds expressions of these ideas in the theories of Michel Focault, Gilles Deleuze, Jacques Lacan and Harold Pinter. The artists I have been investigating include Marcel Duchamp, Ai WeiWei, Ang Lee, Tom Friedman and A Constructed World .The informal nature of the writing attempts to articulate my philosophical stance taken in the studio-based research. My studio research practice comprises collaboration and installations where I construct objects from found materials, and use video, animation, and performance to explore material and spatial equivalences to the concept of body as machine.
