Primena informaciono-komunikacionih tehnologija u Biblioteci Arhitektonskog fakulteta u Beogradu - Danica Radovanovic
Get PDFAccelerating developement of Information-Communication Technologies (ICTs) in the last decade, has been influencing on the usage of some internet services (www, mailing lists, discussion groups) and has broaden their scope from academic surroundings on educational-information centers - libraries. Library of Faculty of Architecture has started from the May 2000, to apply and use some of the internet services in purpose of education and animation of their users. This paper describes experience of one academic library in bringing in and applying modern technologies through selective structuring and difusion of information, as well as action of animation users with aim of expanding, inducing digital and information literacy. Therefore, coordinator and author of the project ArchiWeb has put in a small questionnaire , a poll among the users in purpose to understand their need and improving the work of the service
Introducing Mixed Reality for Clinical Uses
No full textThe advent of mixed reality (MR) has revolutionized human activities on a daily basis, striving for augmenting professional and social interactions at all levels. In medicine, MR tools have been developed and tested at an increasing rate over the years, playing a promising role in assisting physicians while improving patient care. In this chapter, the authors present their initial experience in introducing different MR algorithms in routine clinical practice from their implementation in several neurosurgical procedures to their use during the COVID-19 pandemic. A general summary of the current literature on MR in medicine has also been reported
Individual decision making, group decision making and deliberation
Get PDFEach of us makes a number of decisions, from the less important to those with far-reaching consequences. As members of different groups, we are also actors of group decision making. In order to make a rational decision, a choice-making procedure must satisfy a number of assumptions (conditions) of rationality. In addition, when it comes to group decisions, those procedures should also be “fair.” However, it is not possible to define a procedure of choice-making that would transform individual orders of alternatives based on preferences of perfectly rational individuals into a single social order and still meet conditions of rationality and ethics. The theory of deliberative democracy appeared in response to the impossibility of Social Choice theory. The basic assumption of deliberative democracy is that individuals adjust their preferences taking into account interests of the community. They are open for discussion with other group members and are willing to change their attitudes in order to achieve common interests. Ideally, group members come to an agreement during public discussion (deliberation). Still, this concept cannot completely overcome all the difficulties posed by the theory of social choice. Specifically, there is no solution for strategic and manipulative behavior of individuals. Also, the concept of deliberative democracy faces certain problems particular to this approach, such as, to name but a few, problems with the establishment of equality of participants in the debate and their motivation, as well as problems with the organization of public hearings.

Humanizam i humanizmi: (Ra)stezanje pojma
No full textU ovom radu autori nastoje da ponude pregled različitih učenja koja se
svrstavaju pod kapu humanizma. Mada se rad prevashodno usredsređuje na humani-
stičke doktrine, teoriju humanizma često nije jednostavno razlučiti od huma-
nizma u praksi, te će svakako biti referisano na različite praktične programe
humanizma. I u jednom i u drugom slučaju ispostavlja se da je humanizam toliko
razuđen, ako ne i bezobalan pojam, da je možda uputnije govoriti o humanizmima, u
množini. Iako jedan pregledni članak ne može da predoči podrobnu i sveobuhvatnu
istoriju (ideje) humanizma i sve varijacije kroz koje je on prošao i prolazi kod
svojih značajnih zastupnika, autori veruju da čitaocima može pružiti osnov za
razumevanje i okvir za dalja istraživanja i promišljanja humanizma/humanizama.In this paper, the authors have offered an overview of various teachings that fall
under the umbrella of humanism. Although the paper primarily focuses on the humanist
doctrine, it is often not easy to distinguish the theory of humanism from humanism in
practice. In both cases, it turns out that humanism is such a wide-ranging concept that
perhaps it is instructive to talk about humanisms instead. Although a single review article
cannot present a detailed and comprehensive history of (the idea of) humanism and all
the variations it has gone through, the authors believe that this work can provide readers
with a basis for understanding and a framework for further research and reflection on
humanism/humanisms
Optimizing LRU Caching for Variable Document Sizes
No full textWe analyze a class of randomized Least-Recently-Used (LRU) cache replacement algorithms under the independent reference model with generalized Zipf's law request probabilities. The randomization was recently proposed for Web caching as a mechanism that discriminates between different document sizes. In particular, the cache maintains an ordered list of documents in the following way. When a document of size s is requested and found in the cache, then with probability p s it is moved to the front of the cache; otherwise the cache stays unchanged. Similarly, if the requested document of size s is not found in the cache, the algorithm places it with probability p s to the front of the cache or leaves the cache unchanged with the complementary probability (1 p s ). The successive randomized decisions are independent and the corresponding success probabilities p s are completely determined by the size of the currently requested document. In the case of a replacement, the necessary number of documents that are least recently moved to the front of the cache are removed in order to accommodate the newly placed document
Numerical simulation of the influence of stationary louver and coal particle size on distribution of pulverized coal to the feed ducts of a power plant burner
Get PDFOne of the key requirements related to successful utilization of plasma technology as an oil-free backup system for coal ignition and combustion stabilization in power plant boilers is provision of properly regulated pulverized coal distribution to the feed ducts leading the fuel mixture to a burner. Proper regulation of coal distribution is deemed essential for achieving an adequate pulverized coal concentration in the zone where thermal plasma is being introduced The said can be efficiently achieved by installation of stationary louver in the coal-air mixing duct ahead of the feed ducts of a burner. The paper addresses numerical simulation of a two-phase flow of air-pulverized coal mixture in the mixing ducts, analysing the effects of particle size distribution on pulverized coal distribution to the burner feed ducts. Numerical simulation was performed rising the FLUENT 63 commercial code and related poly-dispersed flow module, based on the PSI-CELL approach. Numerical experiments have been performed assuming a mono-dispersed solid phase with particle diameter ranging from 45 mu m to 1200 mu m. Distance between the louver blades and the resulting effect on the flow profile was analysed as well. Results obtained indicate that the size of coal particles considerably influence the overall solid phase distribution. While fine particles, with diameters at the louver end of the above specified range, almost fully follow the streamlines of the continuous phase, coarser particles, which hit the louver blades, deflect towards the thermal plasma zone. In this manner, a desired phase concentration in the considered zone can be reached For the said reason, installation of stationary louver have been deemed a very efficient way to induce phase separation, primarily due to more pronounced impact of the installed louver on discrete phase flow then the impact on the flow of the continuous phase

Open knowledge and education at the new level of web paradigm
Get PDFAs www, and now web 2.0 is growing by the second, it gives us new possibilities of pedagogical forms, and the main following outcomes: resources, implementation, usage, practice. We will re-evaluate and examine new forms of social networking - theoretical and practical knowledge in academia and science: from implemetation of web roots practice, listservs, eBoards, eZines (alternative art and education forms –then), the usage of eResources in academia, education profession to the wider audience: using larger online open archives, Consortias, digital libraries, repositories, to online social networking applications, science and education blogs.
Author uses and presents data from her Master research paper with relevant results about the usage of the precious online resources, electronic publishing materials within Consortia (that are available in science institutions, academia and libraries). More than thousands and thousands available resources are not used because of many factors that the author explained in one of the chapters in master paper. As indicated in outlines, e-tensions play themselves differently in various institutional geographies. Author took empirical research on three geographic points: USA, Europe (UK and Nederlands) and Serbia.
The Scopes are two paradigms: human factor and digital media educational tools (human-computer interaction and its social impacts), that we use in education systems and professional practice. For the first one is indicated open source educational software, applications and tools for giving information and knowledge. We will also give a short notice on the interest and the usage of the aimed groups of those possiblities (at classes, lectures). For the second, in professional practice we will see how those social knowledge tools have impact on larger science commnity groups (science, educational institutes and institutions) as well as the outcome-feedback.
The point will be given on interaction in open knowledge and education, as well as the notice to the audience of the recent exemplar of implementation of social, interactive knowledge into professional practice and educational system - the concept of web of science which founder is the father of World Wide Web Tim Berners- Lee
