Temperature Measurement of Photovoltaic Modules Using Non-Contact Infrared System

Jovanovic, Ugljesa,Mancic, Dragan,Jovanovic, Igor,Petrusic, Zoran The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.12 No.2

This paper presents temperature measurement of solar photovoltaic modules using the custom-made system composed of an infrared temperature sensor and a microcontroller. The obtained measurement results are processed, displayed and stored on a PC using the custom-made virtual instrument. The proposed system overcomes some of the problems related to the contact sensor application, and at the same time offers accurate readings and better flexibility. The proposed system is especially suitable for applications where the cost is a limiting factor in the choice of measuring system. The conducted analysis and the obtained results have shown an excellent accuracy of the proposed system in comparison to a high quality thermal imaging camera used as the reference instrument.

Local vs. Global Location of Firms and Industries

Jovanovic´, Miroslav N. 세종대학교 국제경제연구소 2003 Journal of Economic Integration Vol.18 No.1

Where economic activity will locate in the future is one of the most important questions in economics. Even though advances in technology have reduced the cost of rtansport, communication and information gathering and processing, hence curtailing the 'distance penalty', local proximity (clusters) of firms that produce similar, competing and/or related products together with supporting institutions still matter. Economies of scale, activity-specific vackward and forward linkages (indivisible production), accumulated knowledge and skills, innovation, existence of sophisticated customers and a fall in transportation costs play relevant roles in the 'protection' of clusters and absolute locationsal advantages of certain locations, 'Globlal'competitiveness often depends on highly concentrated 'local'knowledge, capabilities and common tacit codes of behaviour which can be found in a geographical concentration (cluster) of firms.

Where are the Limits to the Enlargement of the European Union?

Jovanovic´, Miroslav M. 세종대학교 국제경제연구소 1999 Journal of Economic Integration Vol.14 No.3

Protection of the Single Market, monetary integration, institutional and policy reform, as well as enlargement are hot topics in the European Union. This article considers only the economic dimension of the enlargement. Five countries with economies in transition (the Czech Republic, Estonia, Hungary, Poland and Slovenia), and one market economy (Cyprus) negotiate full membership with the European union. Although there are general grounds for the enlargement of the European Union, the process will be much slower that expected by the politicians in both the European Union and the acceding countries. The reasons for such conclusion include high standards that come from the ever growing acquis communautaire which are costly to introduce, implement and enforce. (JEL Classification: F15)

pH control of magnetic properties in precipitation-hydrothermal-derived CoFe₂O₄

Jovanovic, S.,Spreitzer, M.,Otonicar, M.,Jeon, J.H.,Suvorov, D. Elsevier Sequoia 2014 JOURNAL OF ALLOYS AND COMPOUNDS Vol.589 No.-

Cobalt ferrite nanoparticles (CFO NPs) were synthesized using precipitation followed by a hydrothermal treatment. The conditions for precipitation were kept constant, while the pH, the temperature and the synthesis time for the hydrothermal treatment were systematically varied. The results show that the pH plays the dominant role in the formation, growth and crystallization of the desired phase. Furthermore, by controlling the pH the magnetic properties, such as the magnetization and the coercivity of the CFO NPs, can be tuned. An increase in the temperature induced both particle growth and a change of the morphology. The variation of the synthesis time indicated that the hydrothermal reaction proceeds for up to 8h; however, a further prolongation of the synthesis time does not affect the structural and magnetic properties to any significant extent.

Реченичне структуре у роману Време смрти Добрице Ћосића

Jelena Jovanovic Simic,Ivana Jovanovic, 한국슬라브어학회 2023 슬라브어연구 Vol.28 No.1

The paper investigates the syntactic aspects of the composition of the novel Time of Death (first and second books) by Dobrica Ćosić, from the standpoint of theoretical-methodological postulates of text theory, linguistic composition and verbatology. Intra-sentence relationships in statements are discussed, with special reference to verb and noun rection, as well as their mutual relationship. The authors first recognize and describe the ability of language units to influence the form of dependent units that are combined with them, i.e. rectional structures, and based on the analysis of this type of structural cohesion – the research results are presented as determining and describing: appositional constructions in the organization of sentence structures; appositive or dislocated subcategorical determinatives; and attributive provisions with a classification meaning. Therefore, the subject of research are: (1) all forms of connection in appositional constructions – noun, pronoun and adjective and (2) all syntactic procedures of form expansion by adding new elements – apposition, adlocation, collocation, prosthesis, structural expansion. It was determined that in the novel Time of Death by Dobrica Ćosić there are two formal ways of building the structure: (a) congruent and more dominant – most often as three-part sentence structures with a conjunction and a predicate or with a semi-conjunction and a predicate, and (b) a reaction type of structure – with a conjunction and a predicate. On the basis of these findings, two regularities were established: the rules of linear distribution of consecutive sentences and the rules of structural repartition of the meaning pivots of the sentence. The authors conclude that Ćosić's sentence in Time of Death is characterized by linear discursiveness, most often as a connection of consecutive units, in which the syntactic mechanisms of conjunction, adjunction, interjunction and disjunction are particularly activated. Ćosić's syntactic procedure in this novel is defined as 'parable' – i.e. as a procedure with a distinct tendency and ability to build a complex structure by combining comparable microstructures, in the result of which the verbatological and stylistic value of successive constructions is revealed.

Reflections on Human Resources Management in Globalization: Some Critical Aspects

Mica Jovanovic,Ana Langovic Milicevic,Tanja Cvetkovski 동아대학교 동아시아연구원 2011 동아시아 : 비교와 전망 Vol.9 No.3

The paper deals with necessity and importance of human resources management of especially those MNCs operating in global context of cultural diversity and complexity. This is conditio sine qua non for corporate leadership experienced and versed in different languages, religions, beliefs, value system, etc. Further it is stressed that MNCs and managers have to develop conative capability along with trajectories of flexible intercultural management and communication system rooted in different values and traditions.

Environmental Variable and Global Competition for Talent : The Case of Serbia

Mica Jovanovic,Ana Langovic Milicevic,Tanja Cvetkovski 동아대학교 동아시아연구원 2012 동아시아 : 비교와 전망 Vol.11 No.1

Many theorists argue that literature is becoming less and less relevant to the education of young managers. They believe that genuine knowledge is gained by those who "work" since modern environment imposes global business which changes the traditional approach to education. Companies strive to expand their operations abroad, manage "talent" in a more strategic way and change traditional bureaucratic structures. Business communications is becoming intercultural, virtual and horizontal. The situation poses a dilemma- Does the literature appropriately follow these changes? In fact, bridging the gap of academic approach, that is, theory and practice–is the way to create a high-quality manager in the business world. The essential question is- Why does the gap exist? In fact, several studies have shown that managers rarely publish their business practices that can be analyzed from theoretical aspects as well and become useful for the future generations of managers. Some say that is because managers and theoreticians observe the problem from different aspects. Whatever the reason is, if the scholars do researches for themselves, there is the danger that the researches will exclude real world of business. In today's business world where changes are rapid, large and unpredictable, it seems more important than ever for academics to bridge the gap and establish cooperation with the people from practice. The reasons for this are very clear. Firstly, business people, that is, practitioners, can benefit from the theoretical knowledge management. Secondly, scientists will conduct better researches and convey the required knowledge to students and provide them with better understanding of the modern business environment and actions faced by practitioners. And thirdly, bridging this gap is likely to increase our credibility with the business community. The purpose of this research is to provide a brief overview of the forces that shape the environment, including changes that are manifested in the governance of business systems, but in the first place in human resource management.

Нека нерешена питања око пређашњих времена

Jelena Jovanovic Simic,Ivana Jovanovic 한국슬라브어학회 2019 슬라브어연구 Vol.24 No.1

There is extensive literature on aorist and imperfect, whose review would require a much wider space than that of a scientific article, and it does not appear to give us a clearer insight into the nature of the two verbal forms we want to discuss. So for now we have limited ourselves to learning about the meaning of the previous forms, i.e. about Maretić’s idea of ’narrating’, ’reporting’, etc., about Musić’s narration and conversation and about the so-called. ’Experience’, as well as the conclusions that come out of them and which seem to us to contradict the essence of ’past ’.

Вербатолошко-жанровске и прагматичко-семантичке карактеристике пословица као микротекстова

Jelena Jovanovic Simic,Ivana Jovanovic, 한국슬라브어학회 2021 슬라브어연구 Vol.26 No.1

As our analysis has shown, it is a very rich and diverse verbatological registry of paremisational forms and pragmatic functions. We found that relatively often the aesthetic form of proverbs can be seen as a verbatological act. The pragmatic and verbatological dimension of the proverb confirms that speech does not have only a cognitive aspect – redecorate: DESCRIPTIVE, EV ALUA TIVE, DEFINITIVE, HYPOTHETICAL, ASSERTIVE, PERMISSIVE, IDEALIVE, INDICATIVE, etc., which enables to mark or describe the world or determine the facts of reality, is also determined by its function of building interpersonal relationships – redecorate: APPEAL, MALEDICTIVE, RHETORICAL FORMS, EDUCATIVE, CONNOTATIVE, CURSED FORMULAS, SWORN FORMULAS, INSTRUCTIVE, DIALOG FORMS, etc. .
