RANKING OF EU COUNTRIES ACCORDING TO INNOVATION POTENTIAL

In a high-tech society, the main factor of economic development are activities related to research and development (R&D). The purpose of the paper is to rank all 27 countries of the European Union (EU) according to selected indicators of innovation potential. The author singled out five relevant indicators from the Eurostat database (section related to innovation) in the assessment of the conditions for innovation development in the EU using the MOORA (Multi-Objective Optimization on the basis of Ratio Analysis) method. Based on the conducted multi-criteria analysis, the author concludes that Germany, Sweden, France and the Netherlands have the best innovation performance, so that these countries are the closest to achieving the goals of a highly competitive economy and sustainable economic development. On the other hand, Romania, Cyprus, Slovakia and Croatia show the weakest innovation potential, followed by other newer EU members

НАКНАДА ШТЕТЕ ЗБОГ НЕОСНОВАНЕ ОСУДЕ И ЛИШЕЊА СЛОБОДЕ У АНГЛОСАКСОНСКОМ ПРАВУ

The paper analyses the institute of compensation for wrongful conviction and deprivation of liberty in the common law legal systems. It points to the basic difference in approach between common law legal systems and civil law legal systems laws on this issue, where the common law regimes are much more restrictive. It analysed the specifics of the rules on compensation for damages in common law, which can have a negative impact on eligibility for damages to wrongfully convicted persons. The paper specially investigated under which conditions it is possible to achieve compensation for wrongful conviction from the state, as a rule, in the regime of non-legally binding payments, and, exceptionally, in a separate legal regime established by law.У раду је анализиран институт накнаде штете због неосноване осуде и неоснованог лишења слободе у англосаксонском праву. Указано је на основну разлику у приступу англосаконских и европскоконтиненталних законодавстава овом питању, где је режим англосаксонског права знатно рестриктивнији. Анализиране су специфичности правила о накнади штете у англосаксонском праву, која имају неповољан утицај на могућност остваривања права на накнаду штете неосновано осуђених лица. Посебно је истражено под којим условима је могуће право на накнаду штете због неосноване осуде остварити у односу на државу, по правилу у режиму правно необавезујућих исплата, те, изузетно, у посебним правним режимима одређеним законом. &nbsp

Posebno je analizirana funkcionalna zavisnost ekonomskih ušteda u gorivu i inputima za operacije distribucije hraniva i zaštite biljaka. Tabelarno je data procena stepena svih očekivanih ušteda za operacije koje se odnose na pet analiziranih kultura.This paper examined the level of savings in the application of modern technical systems for satellite guidance and control over performing agricultural operations throughout the season. The exemplary property was Agricultural Corporation Belgrade (PKB), which covers about 21,000 hectares of arable land. The effects of plot shape and direction of movement of tractor-attachment units in calculating the savings from reduced overlapping of adjacent passes were studied. The analysis was carried out of savings per crop (maize, wheat, soybean, sugar beet and alfalfa) and the operations for each crop separately, based on the manufacturing technology applied to an exemplary property. Comparing the achieved level of savings, the application of guidance for the type of the most economically viable operations was found as well as the needed equipment level of guidance devices and management. In particular, the analysis involved the functional dependence of the economic savings in fuel and inputs for the operations such as mineral fertilizers distribution and chemical plant protection. The estimates for the degree of anticipated savings for operations related to the five analyzed crops are tabulated

An example of an Android-based secure mobile client application is presented which can be used in the described secure m-healthcare model and it is experimentally evaluated. In the paper, we focus on possible optimization of cryptographic algorithms implemented in the secure Android mobile client application. The presented experimental results justify that security operations related to X.509v3 digital certificate generation and XML/WSS digital signature creation/verification are feasible on some current smart phones and justify the use of the proposed optimization techniques for implemented cryptographic algorithms

Optimization of foil consumption for packing deep frozen fruit

Pri pakovanju duboko zamrznutog voća u PVC folije potrošnja folije je velika i računa se po jedinici mase ili po jedinici dužine. Merenje utroška folije podleže grešci usled brojnih tehnološko - tehničkih problema. Optimizacija rešenja za utrošak folije je bazirana na implementaciji enkodera na postojećim mašinama za pakovanje i ključna je za dobijanje relevantnih rezultata. U radu prikazan je novi model mernog sistema utroška folije koji obezbeđuje niže cene pakovanja.In the case of packing deep frozen fruit in PVC foil, the foil consumption is significant and it is calculated per unit of mass or per unit of length. The measurement of foil consumption can become inaccurate because there are many technological and technical problems. The optimization of solutions for foil consumption is based on the application of encoders on existing packing machines and it is the key for obtaining correct results. This paper shows a model of a foil consumption measuring system, which helps provide a lower price for packing

Recent research on ductility of perforated shear connectors

Significant implementation of Perfobond shear connectors in construction of composite steel-concrete structures resluted in development of entirely new type of shear connectors, denoted as perforated shear connectors. Except the shear resistance of this type of shear connector, the overall behaviour of shear connection is strongly influenced by shear connector geometry. Ductility of shear connector, which is strongly influenced by connectors geometry, defines the behaviour of shear connection. The results of resent research on ductility of perforated shear connectors are obtained from numerical models which are calibrated with results of experimental investigation of this type of shear connector. The results of extensive numerical analysis were used for definition of direct relation between connectors ductility and geometry and presented in this paper

Reliability and sensitivity of the field tests for specific wrestling preparedness evaluation

Predmet ove doktorske disertacije predstavlja ispitivanje mogućnosti dijagnostikovanja specifične pripremljenosti rvača primenom terenskih testova. Na osnovu toga, glavni cilj je bio da se utvrdi nivo pouzdanosti i osetljivosti specifičnih terenskih testova za rvače, u funkciji praktične primenljivosti istih. Generalna pouzdanost testova i osetljivost testova u odnosu na ispitivane grupe, utvrđena je pojedinačnom analizom definisanih parametara pripremljenosti, ispoljenih na testu, kao i analizom specifične funkcionalne i metaboličke reakcije organizma na zadato opterećenje u testovima. Takođe su utvrđene i međusobne relacije definisanih parametara, kao i normativne vrednosti parametara pripremljenosti, ali i definisan optimalni test i model procene pripremljenosti. U istraživanju je učestvovao 31 rvač iz Srbije koji se bave grčko-rimskim stilom rvanja, prosečne starosti 21.61±3.36 godina, juniorskog (10 rvača) i seniorskog (21 rvač) takmičarskog uzrasta. U odnosu na primenjene metode, kao osnovni metod u istraživanju je korišćeno terensko testiranje. U cilju definisanja pouzdanosti dva specifično-terenska testa, koristio se test-retest postupak, i to na dva načina: „pokušaj-za-pokušaj“ i „dan-za-dan“. Ispitanici su testirani primenom sledećih procedura merenja: „Specific Wrestling Fitness Test“ (SWFT) - specifični rvački fitnes test se sastoji iz tri segmenta bacanja po 30 sekundi, između kojih je odmor od 20 sekundi; i „Specific Wrestling Performance Test“ (SWPT) - specifični test rvačke performanse se sastoji iz dva segmenta u trajanju od po 3 minuta, koji vremenski simuliraju rundu u borbi, a između kojih je odmor u trajanju od 30 sekundi. Radi relativizovanja opterećenja u testovima su korićene tri rvačke lutke različite težine (22 kg, 27 kg, 32 kg), a tehnika prednji pojas kao standardno bacanje za sve ispitanike. Za merenje frekvencije pulsa korišćen je Polar H7 Heart Rate Sensor, dok je za utvrđivanje nivo laktata u krvi korišćen laktat analizator Lactate Plus NOVA biomedical...diagnosing the specific preparation of wrestlers using field tests. Based on this, the main aim was to determine the level of reliability and sensitivity of the specific field tests for wrestlers, in the function of practical applicability. The overall reliability of the tests and the sensitivity of the tests in relation to the tested groups were determined by the individual analysis of the defined preparedness parameters expressed on the test, as well as the analysis of the specific functional and metabolic response of the organism to the given load in the tests. Also, mutual relations of the defined parameters are determined, as well as the normative values of the parameters of the preparedness, but also the optimal test and model of the assessment of preparedness was defined. The research involved 31 wrestlers from Serbia dealing with the Greco-Roman style of wrestling, the average age of 21.61 ± 3.36 years, junior (10 wrestlers) and senior (21 wrestlers) competitor age. In regard to the applied methods, field testing was used as the basic method in the research. In order to define the reliability of the two specific field tests, a test-retest procedure was used in two ways: "trial-to-trial" and "day-to-day". The subjects were tested using the following measurement procedures: "Specific Wrestling Fitness Test" (SWFT) - consisted of three throwing segments of 30 seconds, with a break of 20 seconds; and "Specific Wrestling Performance Test" (SWPT) - consisted of two 3-minute segments, simulating a round in combat, with a break of 30 seconds. In order to normalize the load in the tests, three weightlifting dolls of different weights (22 kg, 27 kg, 32 kg) were used, and the technique the front belt as a standard throw for all respondents. The Polar H7 Heart Rate Sensor was used to measure the pulse frequency, while the Lactate Plus NOVA biomedical lactate analyzer was used to determine blood lactate levels..

Maketa servosustava za pozicioniranje

U većini tehničkih sutava javlja se potreba za pozicioniranjem. Uređaji za pozicioniranje takvih sustava najćešće se sastoje od automatski reguliranih elektro-mehaničkih komponenti kojima upravlja računalo. U procesu tumačenja principa automatske regulacije sustava vrlo je važno prikazati usporedbu različitih klasičnih i naprednih metoda regulacije, te njihove praktične izvedbe. Eksperimentalni prikaz procesa regulacije na stvarnom sustavu omogućava studentima da lakše razumiju i savladaju teorije upravljanja servosustavima, pri čemu je nužno biti dobro upoznat s radom klasičnog PID regulatora. U ovom radu obrađen je postupak projektiranja makete regulatora pozicije preko kuta zakreta motora te regulatora brzine koja bi služila u nastavne svrhe. Također projektirano je sučelje za mikrokontrolersko upravljanje koje u sebi sadrži digitalni regulator prema zahtjevima regulacije kuta zakreta istosmjernog motora
