متن کاملThermal Dileptons as Fireball Thermometer and Chronometer
Thermal dilepton radiation from the hot fireballs created in high-energy heavy-ion collisions provides unique insights into the properties of the produced medium. We first show how the predictions of hadronic many-body theory for a melting ρ meson, coupled with quark-gluon plasma emission utilizing a modern lattice-QCD based equation of state, yield a quantitative description of dilepton spectr...
متن کاملReliability and validity testing of an archery chronometer.
Keeping the arrow velocity constant during consecutive shots and responding to "clicker's fall "are considered to be an important feature of archery performance. A specially designed device called an archery chronometer was developed to measure the reaction time of an archer to clicker's fall, arrow velocity, and external factors that may affect arrow velocity. The purposes of this study were t...
متن کاملOn the Special Properties of Graphic and Co-graphic Bondgraphs
The special combinatorial properties of graphic and co-graphic bondgraphs are analysed. A graphic bondgraph is one which has an associated graph, meaning that the two represent the same combinatorial information, expressed in thej’unctions of the bondgraph or the cycles of the graph. Dually a co-graphic bondgraph is one whose dual bondgraph has an associated graph. The combinatorial basis for c...
متن کاملGraphic Matroids
Matroid theory was first formalized in 1935 by Whitney [5] who introduced the notion as an attempt to study the properties of vector spaces in an abstract manner. Since then, matroids have proven to have numerous applications in a wide variety of fields including combinatorics and graph theory. Today we will briefly survey matroid representation and then discuss some problems in matroid optimiz...
