Tiled stove as the unique heating source for single house
Full text linkTitle of the thesis is provocative nature. I wrote it as a response to an article published on 8 July 2016 in the daily newspaper Dnevnik (in annex). Author Marjeta Kralj named it "Iz stanovanj bo treba zmetati neustrezne peči, kamine in štedilnike", which roughly translates to "furnaces, stoves and fireplaces need to be thrown out of houses. The article states the problem of carbon oxides and flotation of fine dust particles PM10 and PM2,5. In the introductory chapters I talk about stovemaking industry in Slovenia. These beginnings date as far as Emona villa and its hypocaust heating system which can be seen even today\ud
in Ljubljana archeology park. I continue by describing the possible execution of different smaller burning devices and their combinations (for example: an extra separated furnace one floor above). The percentage yield of tiled stove are above 75% and when you install a heat exchanger this percentage increases substantially. In this thesis I have also made a simple case on how to heat single-room house with an tiled stove with the appropriate size for heating losses not excieding 8 kW. Before that I have thoroughly considered theoretical bases of calculations which I have derived from standard SIST EN 15544:2009 and documented them. I am putting large emphacies on wood as an energy source, which is highly available and close by to Slovenians. It is coal neutral and as such energy source of the future. I have also researched the possibilities of low emission burnout in small heating appliances. I was\ud
fascinated by the fact that on Slovenian market already sell filters which purify the air of most harmful gasses and dust particles. Among the products there is a smart device "Florian" made by a company named ATech, which automatically calibrates the suction of smoke gasses in chimney pipes. The device increases percentage yield up to 20 %[14]
The efficiency of the pulse ventilation
Full text linkV velikih samopostrežnih trgovinah je problem vzdrževati željene parametre notranjega ugodja. Obravnavan trgovinski center v Ljubljani je velik in ima posebej obremenjene cone z velikimi hladilnimi ali toplotnimi obremenitvami. Te obremenitve še dodatno onemogočajo ustvarjanje željenega ugodja. Povzročajo temperaturno nehomogenost in stratifikacijo, ter višje hitrosti zraka v bivalni coni oziroma prepih. Obravnavan inovativen sistem pulznega prezračevanja omogoča vzpostavitev boljših razmer v prostoru, pri zmanjšani rabi energije. Elementi za difuzijo zraka so enostavni pločevinasti perforirani kanali, ki s svojo patentirano tehnologijo ustvarijo visoko stopnjo indukcije prostorskega zraka, s tem pa učinkovito mešanje celotnega zraka v prostoru, brez večjih lokalnih hitrosti zraka, kot smo jih navajeni pri običajnih difuzorjih. Zaradi indukcije prostorskega zraka lahko zmanjšamo tudi količino svežega vtočnega zraka, to pa prinese velike prihranke energije na dovodnem ventilatorju. Kanali za odtok zraka v prostoru niso potrebni, zato se zmanjšajo stroški namestitve, ter zmanjša raba energije na odvodnem ventilatorju, zaradi zmanjšanja tlačnega padca. Sistem pulznega prezračevanja prinese višje investicijske stroške, vendar velike prihranke energije, ki upravičijo vračilno dobo investicije.In large self-service shops, the problem is to maintain the desired parameters of interior comfort. The discussed trade center in Ljubljana is large and has particularly heavy zones with high cooling or heat loads. These loads make it even more difficult to create the desired comfort. They cause temperature non-homogeneity and stratification, and higher air speeds in the living zone and drafts. The innovative system of pulsed ventilation allows to achieve better room conditions, with reduced energy consumption. The elements for air diffusion are simple perforated sheet metal tubes with patented technology, which create a high rate of induction of the ambient air, and establish effectively mixing the whole air in the room, without high local air velocities, as using regular diffusers. Due to the induction of ambient air, the amount of fresh air can also be reduced, which leads to high energy savings on the feed fan. There is no need for exhaust air ducts in the room, which reduces installation costs and reduces the use of energy in the exhaust fan due to a decrease in the pressure drop. The pulse ventilation system brings higher investment costs, but great energy savings that justify the return period on investment
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
