This is not exactly compact modelling, but it's a nice thing to see:

SPICE-aided modelling of dc characteristics of power bipolar transistors with self-heating taken into account

Janusz Zarbski, Krzysztof GóreckiDepartment of Marine Electronics, Gdynia Maritime University, Morska 83, 81-225 Gdynia, Poland

Abstract
This paper deals with the problem of calculations of the dc characteristics of power bipolar transistors (BJTs) with self-heating taken into account. The electrothermal model of the considered devices dedicated for PSPICE is presented. The correctness of the model was verified experimentally in all ranges of the BJT operation. Two transistors - BD285 and 2N3055 - were arbitrarily selected for investigation. A good agreement between the measured and calculated characteristics of these transistors was observed.

Handedness may effect body perception

post from Machines Like Us - Science at the speed of thought on 04 November 2009 05:52:38 PM. © Machines Like Us - Science at the speed of thought

There are areas in the brain devoted to our arms, legs, and various parts of our bodies. The way these areas are distributed throughout the brain are known as "body maps" and there are some significant differences in these maps between left- and right-handed people.

Some robots get all the girls. Not only is ROPID one of the only toy-sized robots that can run and jump, it likes to walk around with a healthy dose of swagger. The latest creation of Japanese robotics guru Tomotaka Takahashi, ROPID has all the cuteness of an anime hero and some of the moves [...]
