Displaying cliques in graph drawings

Yamamoto, Yosuke 19 September 2010
Relational information represented by graphs can be found in various areas. Understanding completely connected groups of items is useful in studying relational information. However, when displayed in the form of a graph drawing, completely connected graphs contain quadratically many edges relative to the number of their vertices. This may increase the difficulty in identifying useful information, such as maximal cliques, in the graph. This thesis attempts to display the maximal cliques and the cliques contained in two or more maximal cliques in a given graph in an explicit and clear fashion. In order to achieve the goal, the thesis defines two models, the clique-star and the reduced-clique-star, that represent given input graphs. Both representations reduce the number of edges of the original graphs while maintaining the information about the maximal cliques. This thesis shows that six classes of graphs that can be represented by planar clique-star representations, and four classes of graphs that can be represented by planar reduced-clique-star representations. It also empirically shows that small graphs or either very sparse or very dense graphs maybe beneficially represented by planar clique-star or planar reduced-clique-star representations.

Výroba mělkého výtažku pryží / The manufacturing of shallow drawing part by rubber

Klepáč, Patrik January 2008 (has links)
An object of this master thesis is the proposal of variants solving a manufacturing of required part and the selection right technology for single part production of required part from stainless steel 17240 (DIN 1.4301). At the first part of this thesis is briefly reviewed conventional forming and at rest of this thesis is closely reviewed the technology using the elastic tools (rubber, urethane), hydroforming technology and design of proper tool for required part. At the end of this work will be release economics estimation of fine technology and designed tool.

INVERKAN VID VAL AV DRAGSKIVETYP & DRAGSKIVEVINKEL PÅ YT- OCH MATERIALEGENSKAPER AV ETT USKILJNINGSHÄRDBART ROSTFRITT STÅL / The influences of type of drawing die & approach angle on surface and material properties of a precipitation hardenable stainless steel

Bergström, Emma, Hansson, Sara January 2012 (has links)
Detta projekt har haft till syfte att få en ökad förståelse för materialet och dess egenskaper vid dragning. Det har utförts sex olika försök, vilka har genomförts med två olika ingångsvinklar, 12° och 18°, hos sten, liten nibs samt stor nibs. Försöken har genomförts i produktion där prover har tagits ut för att sedan ha analyserats i labb. Resultat från dragprov, hårdhetsprofil, martensithalts- samt smörjmedelsmängdsmätning har studerats och lett fram till slutsatser. Slutsatserna som dragits visar på att ytan på tråden dragen med ingångsvinkel 12° hade färre defekter än tråd som var dragen med 18°. Defekter som hittades på tråd dragen med stor nibs 18° bestod till stor del av tvärsprickor. Över lag såg resultaten liknande ut i samtliga tester för både 12° och 18°, dock var resultatet av tråd dragen med liten nibs 12° avvikande vid flera tester efter första draget. / This project has been designed to get a better understanding of the material and its properties in wire drawing. There have been six different experiments which were conducted with two different drawing angles of three different kinds of drawing dies; regular drawing die, smaller nib and bigger nib. The experiments have been through the beginning of the production where samples have been taken out and then be analyzed in the lab. Results from tensile tests, hardness profile, martensite- and lubrication quantity measurements has been studied and led to the conclusions. The conclusion shows that the surface of the wire drawn with the drawing angle 12° had fewer defects than the wire drawn with 18°. Defects that were found on the wire drawn with the bigger nib 18° consisted largely of transverse cracks. Generally the results were similar in all tests for both 12° and 18°, however, the results was diverge on several tests for the smaller nib 12° after the drawing die.
