Unapređenje metodologije procene bezbednosti i zdravlja na radu za slučaj snežnih lavina izazvanih zemljotresom / Improving the methodology for assessing occupational safety and health in the case ofearthquake-induced snow avalanches

Bajić Senka 22 March 2019 (has links)
<p>Snežne lavine izazvane zemljotresima su fenomen koji se jo&scaron; uvek istražuje, iako je prisutan u skoro svim planinskim regionima &scaron;irom sveta. U okviru ove doktorske disertacije razvijena je i unapređena metoda procene bezbednosti i zdravlja na radu za slučaj snežnih lavina izazvanih zemljotresom. Osnovni cilj unapređene metode je smanjenje rizika na najmanji mogući nivo, odnosno prihvatanje najmanjeg mogućeg rezidualnog rizika, čije dalje smanjenje ili uklanjanje ne bi bilo isplativo. Unapređena metoda uzima u obzir niz faktora (duboku geologiju, sastav stena, visinu snežnog pokrivača, rasprostranjenost kritičnih nagiba, itd.) koji mogu da utiču na pojavu snežnih lavina uzrokovanih zemljotresom. Za verifikaciju metode uzet je skija&scaron;ki centar Kopaonik, koji nije dovoljno istražen, iako je jedan od najvećih centara u jugoistočnom delu Evrope.</p> / <p>Snow avalanches caused by earthquakes are a subject of many researches, even<br />though this phenomenon is present in mountain regions around the world. In this<br />doctoral dissertation, an improved method of assessing occupational health and safety<br />in cases of earthquake-induced snow avalanches has also been developed. The main<br />goal of the improved method is to reduce the risk to the smallest possible level, i.e. to<br />accept the least possible residual risk, the further reduction or removal of which would<br />not be profitable. This method takes into account a number of factors (deep geology,<br />rock composition, snow cover height, critical inclination distribution, etc.) that can affect<br />the occurrence of the earthquake-induced snow avalanches. For the verification of the<br />method, the ski center Kopaonik was analyzed, which has not been sufficiently<br />explored, although it is one of the largest ski centers in south-eastern part of Europe.</p>

Simulace CMOS VLSI obvodů / CMOS VLSI Circuits Simulation

Šťastná, Hilda January 2017 (has links)
This diploma thesis deals with processes of electrical circuits calculations in the last years' worldwide standards like Dymola, MATLAB, Maple or SPICE applications. Circuits calculations are linked with methods for solving linear differential equations, used in this work also by verification of functionality of designed models for CMOS inverter, CMOS NAND, CMOS NOR. Numerical integration method in combination with Taylor series is a suitable method also for parallel calculations of CMOS VLSI circuits. CMOS circuits simulation was implemented with this method in applications in MATLAB language, solving circuits, represented by differential equations. Functionality of the applications was verified by some real examples. Significant acceleration of calculations using Taylor series compared to other methods is an important factor in choosing methods used in circuit simulations.

Revitalizacija i sagorevanje otpadnih transformatorskih i motornih ulja u funkciji zaštite životne sredine / Revitalization and combustion of waste transformer and motor oils in the function of environmental protection

Đorđić Dragiša 10 June 2020 (has links)
<p>U doktorskoj disertaciji je realizovano ispitivanje revitalizacije, parametara sagorevanja i emisije otpadnih transformatorskih i motornih ulja, kao i njihovih dizel me&scaron;avina. Dobijeni eksperimentalni rezultati ukazuju da se nakon revitalizacionog tretmana značajno pobolj&scaron;avaju izolaciona svojstva transformatorskog ulja, &scaron;to je veoma važno za bezbedan rad transformatora, za&scaron;titu životne i radne sredine. Pored toga, rezultati eksperimentalnog ispitivanja procesa sagorevanja ukazuju da se otpadna transformatorska i motorna ulja i njihove me&scaron;avine sa dizelom mogu koristiti kao gorivo u generatorima toplote male snage i u raznim granama procesne industrije, te mogu smanjiti probleme u vezi sa za&scaron;titom životne sredine.</p> / <p>The doctoral thesis cover the testing of revitalization, combustion parameters and emissions of waste transformer and motor oils, as well as their diesel mixtures. The experimental results obtained indicate that after the revitalization treatment, the insulating properties of the transformer oil are significantly improved, which is very important for the safe operation of transformer, environmental protection and work environment. In addition, the results of an experimental test of the combustion process indicate that waste transformer and motor oils and their mixtures with diesel can be used as fuel in low power heat generators and in various branches of the process industry, and can reduce environmental issues.</p>

However, it is (yet not</p><p>completely) a part of some major Serbian<br />dialect dictionaries (from Rječnik, a dictionary<br />by Vuk Stefanović Karadžić to Dictionary of<br />Serbian Vojvodina Speech) as well as the<br />range of general dictionaries.<br />The research implied the semantic field<br />theory developed by Russian ethno-linguist<br />Nikita Tolstoy, which is commonly applied<br />approach in our region. Lexico-semantic and<br />word-formation analysis as well as<br />lexicographic processing were performed<br />applying descriptive and linguo-geographic<br />methods.<br />Sixteen semantic fields were analyzed:<br />Foodstuffs; Meals; Food Preparation; Winter<br />Stores; Milk; Dairy Products and Dishes; Soups<br />and Stocks; Pasta and Savory Dishes; Egg<br />Dishes; Meat Dishes; Meat Products; Meat<br />Types and Cuts; Sauces; Vegetable Dishes;<br />Cakes, Cookies and Sweets; Drinks and<br />Beverages; Festive Foods. The material was<br />lexicographically edited and cartographed.</p>
