Hardware synthesis from DDL description

The details of digital systems can be conveniently input into the design automation system by means of hardware description language (HDL). The computer aided design and test (CADAT) system at NASA MSFC is used for the LSI design. The digital design language (DDL) was selected as HDL for the CADAT System. DDL translator output can be used for the hardware implementation of the digital design. Problems of selecting the standard cells from the CADAT standard cell library to realize the logic implied by the DDL description of the system are addressed

Caoilte sa Luath-Fhiannaíocht

Sa tráchtas seo, déantar iniúchadh ar ról agus ar fheidhm Chaoilte sa luathFhiannaíocht – ó na samplaí is luaithe go dtí c. 1400. Tá mórfhócas ann ar an léiriú a dhéantar ar Chaoilte in Acallam na Senórach agus i nDuanaire Finn go háirithe, ach tagraítear chomh maith do shamplaí níos déanaí den Fhiannaíocht, de réir mar is gá, chun gnéithe ar leith a léiriú. Téitear amach ar ról Chaoilte mar phearsa thairseachúil, mar fhéinní, mar revenant, mar fhile, mar cheoltóir, mar chleasaí agus mar idirghabhalaí idir an traidisiún réamhChríostaí agus luachanna na sochaí Críostaí agus idir an saol daonna agus an saol osnádúrtha. Déantar roinnt de na tréithe agus de na cáilíochtaí a bhaineann le Caoilte a iniúchadh i bhfianaise litríocht an laochais sa traidisiún Gaelach agus sa litríocht chlasaiceach. Scrúdaítear ról Chaoilte mar sheachadóir seantraidisiúin agus mar urlabhbraí thar ceann saoil atá imithe i bhfianaise teoiricí a bhaineann le staidéar na cuimnhe mar atá léirithe ag Assman, Carruthers, Duby agus scoláirí eile. Déantar misteachas Chaoilte agus na Féinne a iniúchadh faoi sholas scríbhinní van Gennep, Turner, Lévi-Strauss, Lewis agus Eliade inter alia. De bhrí go mbaineann An Leabhar Laighneach le pointe i stair na hÉireann ina raibh athruithe cuimsitheacha ag tarlú maidir le cúrsaí sóisialta, polaitíochta, eaglasta agus liteartha, déantar an t-ábhar ann a bhaineann leis an bhFiannaíocht i gcoitinne agus le Caoilte go háirithe a iniúchadh agus déantar an léargas a fhaightear orthusan sna tréimhsí réamh- agus iar-Normannacha a mheas Cuirtear síos ar chuid den neamhsheasmhacht agus den pharadacsúlacht a bhaineann leis an léiriú a dhéantar ar Chaoilte i bhfoinsí éagsúla ón tréimhse atá faoi staidéar. Áitítear, áfach, go mbaineann seasmhacht agus comhleanúnachas nach beag leis na feidhmeanna agus na rólanna a bhíonn aige, ainneoin éagsúlacht na seánraí agus fhad na tréimhse atá i gceist

Argonne National Laboratory Reports

This report is a user's manual for SYN3D, a computer code which uses single-channel, spatial flux synthesis to calculate approximate solutions to two- and three-dimensional, finite-difference, multi-group neutron diffusion theory equations. SYN3D is designed to run in conjunction with any one of several one- and two-dimensional, finite-difference codes (required to generate the synthesis expansion functions) currently being used in the fast reactor community. The report describes the theory and equations, the use of the code, and the implementation on the IBM 370/195 and CDC 7600 of the version of SYN3D available through the Argonne Code Center

Robotics 2010

Without a doubt, robotics has made an incredible progress over the last decades. The vision of developing, designing and creating technical systems that help humans to achieve hard and complex tasks, has intelligently led to an incredible variety of solutions. There are barely technical fields that could exhibit more interdisciplinary interconnections like robotics. This fact is generated by highly complex challenges imposed by robotic systems, especially the requirement on intelligent and autonomous operation. This book tries to give an insight into the evolutionary process that takes place in robotics. It provides articles covering a wide range of this exciting area. The progress of technical challenges and concepts may illuminate the relationship between developments that seem to be completely different at first sight. The robotics remains an exciting scientific and engineering field. The community looks optimistically ahead and also looks forward for the future challenges and new development
