Tests and final integration of the ATLAS semiconductor tracker

The Silicon Tracker (SCT) is part of the Inner Detector at the ATLAS experiment at CERN. Its basic building blocks are 5 different types of silicon strip modules. In total more than 15000 p-on-n single-sided silicon strip sensors of an area of about 61 m2 were used to produce 4088 SCT modules. An overall module production yield of 92% could be achieved, where the silicon modules comply with the tight electrical, thermal and mechanical specifications. The macro-assembly of 2112 barrel modules to the four barrel support cylinders was successfully carried out. The nine disks of one endcap are fully populated with 988 modules, and for the second endcap more than 50% of the modules are already mounted. Test results operating complete barrels will be presented as well as a description of the test setup. The different integration steps of the SCT with the surrounding Transition Radiation Tracker (TRT) will be explained. The installation of SCT and TRT into the ATLAS pit will happen during 2006

POF - polymer optical fibres

Tato práce se zaměřuje na polymerová optická vlákna (POF). Jsou v ní popsány základní vlastnosti polymerových optických vláken, materiály pro výrobu a metody výrobních procesů. V dalších kapitolách jsou uvedena jednotlivá vlákna, která se liší rozdílnými indexy lomu a průměrem vlákna. Také jsou rozebrány konektory používané pro spojování. Jako velmi vhodné pro domácí instalaci se hodí řešení bez konektorů Optolock. Dále jsou uvedeny oblasti, kde je možné použít POF. Prosadit se může v automobilovém průmyslu, domácích sítích nebo jako senzor. Praktická část obsahuje návrh měřícího polygonu a návrh FTTH s využitím POF pro rozvod v domě, kde je zvolena topologie P2P. Je také zpracován návrh rozvodu POF v bytě. Pro instalaci v bytě jsou cenově porovnány prvky sítě mezi rozvody POF a UTP cat.6 kabeláží. Z tohoto porovnání vychází mnohonásobně levněji verze s UTP kabeláží. Závěrečná kapitola zhodnocuje náročnost práce s POF. Popisuje přípravu vlákna před komunikací a vytvoření malé experimentální sítě. Celkové poznatky jsou shrnuty v závěru.This work focuses on polymer optical fiber (POF). It describes basic properties of polymer optical fibers, materials for production and methods of manufacturing processes. In following chapters are given individual fibers that vary different refractive indexes and diameter of fiber. Also there are analyse connectors which are used for joining. As very suitable solution for home installation seems to be using the system Optolock without connectors. In the work is also written several areas where it is possible to use the POF. It can break through in automotive industry, home networks or as a sensor. The practical part contains measuring polygon draft and FTTH proposal using POF for distribution system in the house, where P2P topology is choosen. It´s also made a proposal for distribution of POF in the apartment. For installation in the apartment prices of network components are compared between POF distribution and UTP cat.6 cabling. UTP cat.6 is in this comparison many times more cheaply. Final chapter evaluate demands on work with POF fibers. Describes preparation of fiber before communication and creation of small experimental network. Important findings of the work are summarized in the conclusion.

Projektiranje konstrukcije glavnog rebra tankera s dvobokom prema hamoniziranim IACS CSR Pravilima

Kroz ovaj rad provedena je analiza utjecaja dvaju projektnih parametara (razmak uzdužnjaka i razmak okvira) na masu konstrukcije tankera s dvobokom s ciljem dobivanja optimalnog razmještaja uzdužno nosivih elemenata konstrukcije. Na temelju referentnog modela, izrađeno je dodatnih 16 varijanti pri čemu su korištene različite kombinacije razmaka okvira i razmaka uzdužnih elemenata. Kako bi se osigurala relevantnost usporedbe različitih varijanti, nužno je bilo dimenzionirati konstrukcijske elemente tako da svi kriteriji čvrstoće budu zadovoljeni. Dimenzioniranje elemenata konstrukcije provedeno je pomoću programa MARS klasifikacijskog društva BV, prema usuglašenim IACS Pravilima (H-CSR BC&OT) koja su stupila na snagu 01. srpnja 2015. godine. Dobiveni rezultati uspoređeni su s obzirom na postignutu masu konstrukcije, moment otpora i moment tromosti glavnog rebra te postignuti granični moment savijanja, na temelju čega su predloženi optimalni parametri konstrukcije. Ključne riječi: konceptualna faza višekriterijskog projektiranja, brodska konstrukcija, projektni parametri, razmak uzdužnjaka, razmak okvira,granični moment savijanja, tanker s dvobokom, harmonizirana IACS CSR Pravil

Remote Shutdown of Heavy Duty Vehicles

Today, vehicles are equipped with advanced electronics and complex alarm systems but still vehicle and cargo theft is a huge problem around the world. After struggling with this issue for several decades, the government in Brazil finally had enough and voted that all new vehicles manufactured or imported to the country are required to be equipped with an electronic device enabling tracking and immobilization of the vehicle if stolen. Remote immobilization could be a possible solution to prevent vehicle theft and also give the authorities a way to reclaim valuable cargo from stolen vehicles. Since Scania was already developing a telematic unit with the purpose of tracking vehicles and analyzing vehicle data, this thesis was started to investigate if it was possible to use the unit and the current system for remote immobilization as well. Security of the system would be the key issue since a flaw in security could give unauthorized access to stop vehicles and this would certainly be a disaster. A prototype system was created to test the reliability and performance of the system

Potrjevanje neformalnega izobraževanja in priložnostnega učenja z evropske perspektive – povezovanje postopkov potrjevanja z nacionalnim ogrodjem kvalifikacij

The paper analyses European policy on the validation of non-formal and informal learning, which is presented as a “salvation narrative” that can improve the functioning of the labour market, provide a way out from unemployment and strengthen the competitiveness of the economy. Taking as our starting point recent findings in adult education theory on the validation of non-formal and informal learning, we aim to prove the thesis that what European validation policy promotes is above all economic purpose and that it establishes a “Credential/Credit-exchange” model of validation of non-formal and informal learning. We proceed to ecxamine the effect of European VNIL policy in selected European countries where validation arrangements are linked to the qualifications framework. We find that the “Credential/ Credit-exchange” validation model was first established in a few individual European countries and then transferred, as a “successful” model, to the level of common European VNIL policy.V prispevku analiziramo evropsko politiko potrjevanja neformalnega izobraževanja in priložnostnega učenja, ki je predstavljena kot »pripoved odrešitve« za izboljšanje delovanja trga dela, izhod iz brezposelnosti in krepitev konkurenčnosti gospodarstva. Izhajajoč iz sodobnejših spoznanj v teoriji izobraževanja odraslih o vrednotenju neformalnega izobraževanja in priložnostnega učenja, dokazujemo tezo, da evropska politika vrednotenja spodbuja predvsem ekonomski namen, kakor tudi vzpostavlja »kvalifikacijsko/ kreditni« model potrjevanja neformalnega izobraževanja in priložnostnega učenja. V nadaljevanju preučujemo vpliv evropske politike potrjevanja neformalnega izobraževanja in priložnostnega učenja v izbranih evropskih državah na primeru povezovanja postopkov potrjevanja z ogrodjem kvalifikacij ter ugotavljamo, da se je »kvalifikacijsko/kreditni« model potrjevanja uveljavil najprej v določenih evropskih državah in se kot »uspešen« model prenesel na raven skupne evropske politike potrjevanja neformalnega izobraževanja in priložnostnega učenja

Short-Term Study Abroad for Pre-service Teachers: Personal and Professional Growth in Brighton, England

This study examines the personal and professional development of 34 pre-service teachers who participated in a study abroad program for education majors in Brighton, England. The participants completed a variety of assignments and learning activities before, during, and after the program, including 20 hours of observation in area schools. The results indicate that in terms of personal development, the pre-service teachers experienced increased levels of self-confidence, autonomy, tolerance for ambiguity, flexibility and adaptability, and interpersonal skills. Professionally, the participants identified the role of culture in education and pedagogy, described being better equipped to work with diverse learners in the United States, and developed instructional strategies to use in their future classrooms
