Pristup zasnovan na performansama u projektovanju prostornih struktura slobodne forme

This paper is related to the fact that use of computational tools for form generation, analysis and digital fabrication (CAD/CAM/CAE) in an efficient way enables accurate representation of ideas, simulation of diverse impact and production of rational design solutions. Application of geometrical and numerical computational methods and adoption of performance based priorities enables formal exploration in constrained conditions and improvement of architectural engineering design process. Implementation of advanced technologies in 3D digital design process facilitates production of unconventional complex designs, their verification by construction of physical models and experimental diagnostics, as phase preceding construction of real structure. Within this work concept that provides design of non-standard, context-specific, freeform structure using rapid prototyping technology and 3D optical measurement will be reviewed. The analyzed design solution of roof structure above atrium of National Museum in Belgrade has a function to demonstrate the effectiveness of this approach.Rad je povezan sa činjenicom da je korišćenjem alata za generisanje forme, analizu i digitalnu proizvodnju (CAD/CAM/CAE) na efikasan način omogućena precizna prezentacija ideja, simulacija različitih uticaja i produkcija racionalnih projektnih rešenja. Primena geometrijskih i numeričkih kompjuterskih metoda i usvajanja prioriteta zasnovanih na performansama omogućava formalna istraživanja u ograničenim uslovima i unapređenje procesa projektovanja u oblasti arhitektonskog inženjerstva. Implementacija naprednih digitalnih tehnologija u 3D proces projektovanja omogućava produkciju nekonvencionalnih kompleksnih oblika, njihovu verifikaciju konstrukcijom fizičkih modela i eksperimentalnu dijagnostiku, kao faze koja prethode izgradnji realne strukture. U okvirima ovog rada razmatraće se koncepti koji omogućavaju projektovanje nestandardne, kontekstualno specifične strukture slobodne forme primenom tehnologije brze proizvodnje prototipova i 3D optičkog merenje. Analizirano projektno rešenje krova iznad atrijuma Narodnog Muzeja u Beogradu u funkciji je potvrđivanja efikasnosti ovakvog pristupa

Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

Meta-analyses from a collaborative project in mobile lifelong learning

This paper focuses on the use of mobile technologies in relation to the aims of the European Union’s Lifelong Learning programme. First, we explain the background to the notion of mobile lifelong learning. We then present a methodological framework to analyse and identify good practices in mobile lifelong learning, based on the outcomes of the MOTILL project (“Mobile Technologies in Lifelong Learning: best practices”). In particular, we give an account of the methodology adopted to carry out meta-analyses of published literature and accounts of mobile learning experiences. Furthermore, we present the results of an implementation of our Evaluation Grid and the implications arising from it in terms of management, pedagogy, policies and ethical issues. Finally we discuss lessons learnt and future work

Towards the 3D Web with Open Simulator

Continuing advances and reduced costs in computational power, graphics processors and network bandwidth have led to 3D immersive multi-user virtual worlds becoming increasingly accessible while offering an improved and engaging Quality of Experience. At the same time the functionality of the World Wide Web continues to expand alongside the computing infrastructure it runs on and pages can now routinely accommodate many forms of interactive multimedia components as standard features - streaming video for example. Inevitably there is an emerging expectation that the Web will expand further to incorporate immersive 3D environments. This is exciting because humans are well adapted to operating in 3D environments and it is challenging because existing software and skill sets are focused around competencies in 2D Web applications. Open Simulator (OpenSim) is a freely available open source tool-kit that empowers users to create and deploy their own 3D environments in the same way that anyone can create and deploy a Web site. Its characteristics can be seen as a set of references as to how the 3D Web could be instantiated. This paper describes experiments carried out with OpenSim to better understand network and system issues, and presents experience in using OpenSim to develop and deliver applications for education and cultural heritage. Evaluation is based upon observations of these applications in use and measurements of systems both in the lab and in the wild.Postprin
