Seismic design of steel frames according to the Eurocode 8 by utilizing SAP 2000
No full textV diplomski nalogi je bila narejena ocena ustreznosti računalniškega programa SAP 2000 za namen dimenzioniranja jeklenih konstrukcij na potresnih območjih. Vsebinsko se diplomsko delo deli na dva dela. V prvem delu so povzeta splošna pravila in pravila za projektiranje jeklenih stavb v skladu s slovenskim standardom SIST EN 1998-1:2004 (EC8), ki podaja načela in zahteve za potresno odporno načrtovanje stavb. V drugem delu pa so opisani postopek dimenzioniranja s programom SAP 2000 ter ugotovitve v zvezi s skladnostjo standarda EC8 in postopka dimenzioniranja s programom SAP 2000. Sledi dimenzioniranje dvoetažnega jeklenega okvira in primerjava rezultatov z referenčnimi rezultati iz Priročnika za projektiranje gradbenih konstrukcij po standardih Evrokod. Prikazano je tudi delo s programom na konkretnem primeru, vse od začetnega modeliranja konstrukcije, potrebnih nastavitev parametrov za dimenzioniranje do samega dimenzioniranja konstrukcije. Obravnavan je tako ravninski kot prostorski model konstrukcije. Kljub temu da program prihaja iz Združenih držav Amerike, lahko iz primerjave rezultatov sklepamo, da je program povsem primeren za uporabo tudi v Evropi. Proizvajalci programa so tako poleg vseh večjih svetovnih standardov v sistem delovanja programa korektno vključili tudi evropske standarde Evrokod.The adequacy of SAP 2000 software for seismic-resistant design of steel frames was evaluated in the Thesis, which is divided in two parts. In the first part a brief summary of the Slovenian standard SIST EN 1998-1:2004 (Eurocode 8) for design of structures for earthquake resistance is presented, whereas the second part deals with the description of algorithm for capacity design of steel frames, which is implemented in the SAP 2000, and involves an illustrative example of design of two storey steel buildings according to Eurocode 8. Throughout the example building, which was analysed as 2D or 3D building, we demonstrated design process by using SAP 2000 and compared results with those provided by the "Priročnik za projektiranje gradbenih konstrukcij". From comparison we concluded that SAP 2000 is appropriate software for design of steel frames in earthquake prone regions since adequately treats most of capacity design principles prescribed in Eurocode
Boendeutvecklingen för utvecklingsstörda i Sverige 1971-1982
No full textBoendestandarden för utvecklingsstörda i Sverige 1982 har förbättrats betydligt sedan 1971. Detta har förhoppningsvis också medfört betydande framsteg i den sociala intellektuella utvecklingen för utvecklingsstörda. Mycket återstår dock att göra för dem som fortfarande bor på tunga och traditionella institutioner, framhåller i nedanstående artikel Teut Wallner, psykolog vid byrå S 5, Socialstyrelsen
Improved multimer prediction using massive sampling with AlphaFold in CASP15
No full textAlphaFold2 has revolutionized structure prediction by achieving high accuracy comparable to experimentally determined structures. However, there is still room for improvement, especially for challenging cases like multimers. A key to the success of AlphaFold is its ability to assess and rank its own predictions. Our basic idea for the Wallner group in CASP15 was to exploit this excellent scoring function in AlphaFold by massive sampling. To achieve this goal, we conducted AlphaFold runs using six different settings, using templates, without templates, and with an increased number of recycles for both multimer v1 and v2 weights. In all instances, we enabled dropout layers during inference, allowing for sampling of uncertainty and enhancing the diversity of the generated models. In total, 274 289 models were generated for the 38 targets in CASP15, with a median of 4810 models per target. Of these 38 targets, 10 were high quality, 11 were medium quality, 11 were acceptable, and only 6 were incorrect. The improvement over the baseline method, NBIS-AF2-multimer, is substantial, with the mean DockQ increasing from 0.43 to 0.56, with several targets showing a DockQ score increase of +0.6 units. Remarkable, considering Wallner and NBIS-AF2-multimer were using identical input data. The success can be attributed to the diversified sampling using dropout with different settings and, in particular, the use of multimer v1, which is much more susceptible to sampling compared with v2.

Hang On To Your Hats
No full textThis reading textbook from the 80's shows the place fables have had in education recently. Two fables appear. TT (156), adapted by Arthur Yorinks and illustrated by Ronald LeHew, uses simple cartoon figures and presents the turtle's talkativeness as a conscious stance. Flying was so much fun. The turtle had to say something. So he began to talk. He fell into water, said that he thought he talked too much, and did not go anywhere after that. If I was a child, I think I would not be eager to read many more stupid and childish stories of this sort. In WS (178), adapted by Regina Neuman and illustrated by John Wallner, the wind, an arrogant bully, picks out a little girl and asks if the sun can make her take off her green coat. The wind of course claims to be able to do it.This is a hardbound book (hard cover)Regina Neuman et a
