2014.This final thesis shows the procedure of constructing jib crane with a winch and the
mechanisms for lifting loads and managing the winch. Transport capacity of jib crane with a
hook is 5 tons, the length of the console is 8 metres while the lifting height reaches 6 metres.
The mechanism for compensation of altercation of the height of the load during the operation
of the mechanism for managing the winch is derived as a scissor type mechanism. The impact
of the scissor type mechanism itself on the operation is compensated with the counterweight.
The introductory part presents several conceptual solutions of constructing the console
crane. The main part deals with the calculation of transport construction, mechanisms for
lifting loads and managing the winch, as well as the calculation of the scissor type
mechanism. The end of the thesis reviews the technical documentation of the constructed
crane.
3D model and the technical documentation were made in the program package called

Digital Shadows of Mental States: Exploring the Behaviour of Large Language Models with Representation Engineering
No full textLarge Language Models (LLMs) have emerged as powerful tools at the intersection of artificial intelligence and cognitive science, demonstrating remarkable capabilities in language understanding, generation, and human-like cognitive behaviours. Recent advances in LLM technology have opened new possibilities for modeling complex psychological phenomena, including mental health conditions such as depression. This study investigates the capacity of LLMs to simulate depressive cognitive states and their responses to psychological interventions. Specifically, we examine how representation engineering techniques can be used to model and modify psychological states in LLMs, focusing on the differential effects of intrinsic versus extrinsic goal interventions based on self-determination theory. We employed a three-stage methodology: (1) fine-tuning a Mistral-7B-Instruct model on a curated dataset derived from the Psych 8K corpus to create a “depressed” baseline state; (2) applying representation engineering techniques to generate and implement psychological intervention vectors based on intrinsic and extrinsic goal frameworks; and (3) evaluating the model’s responses using quantitative mood assessments and behavioral analysis. The study suggested observable differences between intrinsic and extrinsic goal interventions on the LLM’s simulated psychological state. Intrinsic goal interventions (self-acceptance, personal growth, community feeling) appeared to show greater positive trends on the model’s reported mood and cognitive patterns compared to extrinsic goal interventions (financial success, social recognition, appealing appearance). Community and engagement emerged among the highest-performing interventions in the tested approaches. These findings contribute to the growing body of work suggesting LLMs may serve as computational models for psychological research, showing patterns that align with established psychological principles such as the differential impact of intrinsic versus extrinsic motivations on well-being. The results support the use of LLMs as cost-effective tools for piloting psychological experiments and exploring therapeutic mechanisms before resource-intensive human trials
Electronic properties and phase transitions of strongly correlated systems : organic conductors and manganites
No full textU fokusu ove doktorske disertacije su sustavi s bogatim faznim dijagramima, jakim elektronskim korelacijama i dimenzionalnosti od 3D do kvazi-1D: 3D manganiti La1−xCaxMnO3 (x > 0.5) kod kojih se pojavljuje faza uređenja naboja (CO), 2D organski vodiči α-(BEDT-TTF)2I3 koji pokazuje CO s nabojnim prugama i κ-(BEDT-TTF)2Cu2(CN)3 gdje faza CO vjerojatno ne postoji te kvazi-1D organski vodič TTF-TCNQ karakterističan po uzastopnim faznim prijelazima u stanje vala gustoće naboja. Uzorci su karakterizirani uglavnom magnetotransportnim tehnikama (otpornost, magnetootpor, anizotropija magnetootpora i Hallov efekt). U manganitima su detektirani fazni prijelazi iz paramagnetske u CO fazu, prisustvo mehanizma vodljivosti preskakanjem (VRH) ovisnog o spinu i koncentraciji x u CO fazi te smanjivanje magnetootpora i anizotropije magnetootpora s povećanjem x. Ovi rezultati su interpretirani pomoću koegzistencije feromagnetske i antiferomagnetske faze za 0, 5 0.5) with a charge order phase (CO), quasi-2D organic conductors α-(BEDT-TTF)2I3 which has a CO phase with charge stripes and κ-(BEDT-TTF)2Cu2(CN)3 where a CO phase probably does not exist and quasi-1D organic conductor TTF-TCNQ known for successive phase transitions to a charge density wave state. The samples were characterized by magnetotransport techniques (resistivity, magnetoresistance, anisotropy of magnetoresistance and Hall effect). In manganites we detected phase transitions from a paramagnetic to the CO phase, the presence of spin and concentration x dependent variable range hopping mechanism (VRH) and decreasing of magnetoresistance and anisotropy of magnetoresistance with increasing x. These results were interpreted by a coexistence of a ferromagnetic and an antiferromagnetic phase for 0, 5 < x ≤ 0, 58. Our results, like many others, show that there are no phase transitions in κ-(BEDT-TTF)2Cu2(CN)3. We proposed 2D VRH mechanism whose origin is ascribed to disorder in the anion network. In α-(BEDT-TTF)2I3 our results show the presence of the CO phase, the dominance of holes in the semimetalic state and the absence of VRH mechanism below the CO phase transition. Hall effect results in TTF-TCNQ were obtained for the first time at low temperatures and they showed the presence of all three phase transitions. We resolved open questions of old results and suggested that at high temperatures electrons and holes equally contribute to the conductivit

The Reception of Jacques Maritain in Croatia During the Twentieth Century
No full textU radu se prikazuje i analizira recepcija francuskog filozofa Jacquesa Maritaina (1882 – 1973) u Hrvatskoj tijekom 20. stoljeća. Prate se prijevodi njegovih članaka i knjiga, članci o Maritainu i njegovim djelima te utjecaj nekih Maritainovih ideja na hrvatske mislioce.
Na prve odjeke njegove misli nailazimo početkom 1920-ih. Već pri prvom spomenu Maritaina 1921. godine Matija Petlić ga predstavlja kao velikog i značajnog filozofa, osobito za katoličku misao. Maritain se u filozofskom smislu intenzivnije prihvaća tijekom 1930-tih kao najznačajniji neotomist i jedan od predvodnika personalističkog pokreta, kad dobiva epitete: »katolički vođa u filozofskim idejama«, »najjači predstavnik kršćanske filozofije«, »uvažen filozof i obraćenik«, filozofski autoritet«, »slavni francuski filozof« i slično. U tome prednjače katolički časopisi Nova revija, Život, Vrhbosna, Luč i Duhovni život.
U 1930-im pojavljuju se i prvi prijevodi njegovih djela: Religija i kultura (1935) i Anđeoski naučitelj (1936). Ovo drugo djelo pružilo je povod žestokoj polemici o tomizmu kao jedinom ispravnom filozofskom katoličkom pogledu na svijet između dominikanca Hijacinta Boškovića i franjevca Karla Balića. Njihov sukob zasjenio je sva druga razmatranja o Maritainu, iako je bilo vrijednih prinosa, osobito u radovima Đure Gračanina, Stjepana Zimmermanna, Dušana Žanka i Bogdana Radice.
Nakon Drugoga svjetskog rata uslijedila je represija prema svima koji nisu prihvaćali proklamirani marksistički pogled na svijet, a za takvu ideologiju Maritain je bio nepoželjan mislilac. U ocjenama neotomizma i personalizma beogradski marksistički filozofi Dragan Jeremić i Radmila Šajković prikazuju Maritainovu misao u negativnom svjetlu, ali značajnija filozofska kritika izostaje. Maritain se u poratnom dobu rijetko spominje, a iznimka su personalističko-neotomistički časopisi hrvatske emigracije, osobito Osoba i duh i Glas sv. Antuna. U njihovim člancima, osobito Hijacinta Eterovića, dominira tematika Maritainove političke filozofije i filozofije prava.
Slabljenjem krutog poratnog ideološkog stava i svojevrsnom liberalizacijom bivše Jugoslavije u 1960-tima i na području kulture i filozofije događaju se ograničeni demokratski pomaci. Sredinom 1960-ih, osobito u razdoblju Drugoga vatikanskog koncila, Maritain je sve prisutniji u oživljenom katoličkom tisku, dok ga marksistička misao prešućuje ili spominje uzgredno. Prvi sustavniji poslijeratni članak o Maritainovoj misli objavljuje Andrija Bonifačić 1966. godine, a kasnije ga u svojim radovima izrazitije tematiziraju i spominju Tomo Vereš, Ante Kusić i Radovan Grgec.
U razdoblju 1989–1995 objavljeni su prijevodi četiriju njegovih djela: Cjeloviti humanizam (1989), Filozofija povijesti (1990), Čovjek i država (1992) i Tri reformatora: Luther, Descartes, Rousseau (1995). S propašću socijalizma ne dolazi do nove kvalitete u recepciji Maritaina. Iako je bilo očekivano da u društvu i državi koja mijenja državni i društveno-politički status pitanja o demokršćanskoj orijentaciji, europskim integracijama i ljudskim pravima rezultiraju ozbiljnijim raspravama, a koje ne bi bile moguće bez poziva na Maritaina, to se nije dogodilo. Maritain se i dalje učestalo usputno spominje na marginama ili u bilješkama različitih tekstova, a očit je nedostatak sintetičkih radova o njegovoj misli. Malo je prevedenih djela iz njegova bogatog opusa, a Maritain je samo djelomično poznat na nekim, a uglavnom nepoznat na mnogim područjima svog djelovanja. Iako je razvidna tendencija, za koju bi se moglo tvrditi da je i konstanta u Hrvatskoj, da se Maritain prenaglašava tamo gdje ne treba, a ne spominje tamo gdje treba, razni se mislioci izjašnjavaju o njegovoj nespornoj veličini.This article examines the reception of the French philosopher Jacques Maritain (1882–1973) in Croatia during the twentieth century, including Croatian translations of Maritain’s books and essays, articles on Maritain and his work, as well as the influence of some of his ideas on Croatian philosophers and other thinkers.
The reception of Maritain’s thought in Croatia may be traced from the beginning of the 1920s. Matija Petlić introduced him in 1921 as a major and important philosopher, especially for the Catholic thought. Philosophical reception of Maritain gained in prominence in the 1930s, when, as a leading neo-Thomist and one of the distinguished figures of the personalistic movement, he was recognised as “Catholic leader in philosophical ideas,” “the most prominent exponent of Christian philosophy,” “foremost philosopher and convert,” “philosophical authority,” “famous French philosopher,” and the like, mainly by the Catholic journals Nova revija, Život, Vrhbosna, Luč and Duhovni život.
In the 1930s, two of Maritain’s books saw their Croatian translations: Religija i kultura [Religion and Culture] in 1935, and Anđeoski naučitelj [The Angelic Doctor: The Life and Thought of Saint Thomas Aquinas] in 1936. The latter incited vehement polemics on Thomism as the only true Catholic philosophical worldview between the Dominican Hijacint Bošković and Franciscan Karlo Balić. Their dispute overshadowed all other research of Maritain’s philosophy and some valuable contributions, especially in the works of Đuro Gračanin, Stjepan Zimmermann, Dušan Žanko, and Bogdan Radica.
The period after WWII was marked by repression against all those who refused to accept the generally proclaimed Marxist worldview, and from the standpoint of that ideology, Maritain was an ‘undesirable’ thinker. In their assessments of Neo-Thomism and personalism, Belgrade Marxist philosophers Dragan Jeremić and Radmila Šajković present Maritain’s philosophy in a negative light, failing to provide a more significant philosopical criticism. In the post-War period Maritain was rarely mentioned, with the exception of personalistic and neo-Thomist journals of Croatian emigration, especially Osoba i duh and Glas sv. Antuna. In their articles, particularly those of Hijacint Eterović, dominates the theme of Maritain’s political philosophy and philosophy of law.
By the 1960s, the rigid ideological framework characteristic of the post-War Yugoslavia gradually gave way to more democratic, though limited, changes in the field of culture and philosophy. In the mid-1960s, in the revived Catholic press, especially since the Second Vatican Council, Maritain appears more often, while the Marxist philosophers either ignored him or referred to him randomly. The first post-War systematic article dealing with Maritain’s thought was published by Andrija Bonifačić in 1966, and the philosophers and editors who in their works draw more attention to Maritain are Tomo Vereš, Ante Kusić, and Radovan Grgec.
In the period 1989–1995, the translations of four of his works were published: Cjeloviti humanizam [Integral Humanism] (1989), Filozofija povijesti [On the Philosophy of History] (1990), Čovjek i država [Man and the State] (1992), and Tri reformatora: Luther, Descartes, Rousseau [Three Reformers: Luther, Descartes, Rousseau] (1995).
The downfall of socialism and dismemberment of Yugoslavia brought no new quality to the reception of Maritain in Croatia. Given the circumstances, it may have been expected that in a state and society that was changing its sovereign frame and socio-political status issues such as Demochristian orientation, European integration and human rights should result in serious discussions, in which Maritain would
definitely have his place, that, however, was not the case. Maritain is still frequently mentioned, though in cursory remarks and in the footnotes of various texts, with a more than evident absence of comprehensive works on his thought. Merely a few books from his rich opus have been translated. Only a few fields of Maritain’s broad scope of activity have been partially highlighted. Despite an apparent tendency, which may rightly be described as a constant in Croatia, to attach more importance to Maritain where it is inappropriate and not mention him at all where appropriate, various thinkers continue to acknowledge his indisputable greatness
The Influence of Personalism on Croatian Chatolic Social Thinkers in the 1930s
No full textFrancuski personalizam utjecao je na katoličke socijalne mislioce u Hrvatskoj tijekom 1930-tih, naročito na Milana Ivšića, Jurja Šćetinca i Bonifacija Perovića, predvodnike katoličke socijalne misli tog doba. Oni kritikom postojećih sustava pokušavaju graditi sustav temeljen na kršćanskim vrijednostima osobe i vlastitog narodnog duha.
Milan Ivšić detaljno istražuje ekonomske teorije, njihovu povijest i metodologiju, kao i aktualne gospodarske prakse, vodeći se idejama dostojanstva ljudske osobe i brige za pravednost pa ga autor stoga svrstava u preteče ekonomskog personalizma. Prihvaćajući katolički solidarizam i razvijajući zadrugarsku ideju Ivšić se zalaže za promjenu postojećeg društvenog i pravnog poretka u skladu s načelima personalizma, ali ističe i uvjet da taj poredak mora odgovarati povijesnom društvenom ustroju hrvatskog naroda.
Na Ivšićevu tragu nastaje djelo Jurja Šćetinca, koje se temelji na personalističkoj kritici individualističko-liberalne ekonomije kapitalističke epohe. Zauzimajući se za uravnotežen odnos rada i kapitala, razvoj osobe i zaštitu ljudskog dostojanstva Šćetinec u svojim spisima o korporativizmu daje prednost svim gospodarskim i političkim organizacijama ili uređenjima koja zastupaju takav stav.
Bonifacije Perović najizrazitiji je predstavnik personalističkog smjera u hrvatskoj katoličkoj socijalnoj misli. U 1930-im i kasnije u više navrata on ne samo da ističe utjecaj personalizma na hrvatsku katoličku misao nego i tvrdi da je personalizam kretanje u okviru katoličkog socijalnog pokreta. Perović razvija kritiku kapitalizma, marksizma, formalne demokracije, uvijek ističući potrebu za izgradnjom novog sustava, koji je ukorijenjen u čovjeku kao osobi i u svom narodu. Svoj nauk izložen u brojnim prijeratnim i poslijeratnim tekstovima zaokružuje u trilogiji o sadašnjosti i budućnosti hrvatskog društva (1971–1979), gdje je polazište svih rasprava – čovjek kao osoba.In his work, the author is questioning the influence of French personalism on Croatian catholic social thinkers, especially those active during the 1930s. This influence is particularly noticeable in the work of Milan Ivšić, Juraj Šćetinec and Bonifacije Perović, leaders of the social thought of that time. By criticizing the existing system, they were trying to create the new one based on Christian personal values and personal national spirit.
The author recognizes Milan Ivšić to be a forerunner of so called economic personalism because of his detalied research of economic theory, history and methodology, as well as, at that time, contemporary business practices in the light of human dignity and justice. By accepting christian solidarity and developing the co-operative idea, Ivšić advocated the change of the existing social and legal system to be more in line with the principles of personalism but taking into account hystoric and social values of Croatian people. Along the same lines, we can find work of Juraj Šćetinac in search for personalists values in economic life criticizing the individual and liberal attributes of capitalism. Šćetinac pleaded for a balanced relationship between labor and capital, personal development and protection of human dignity.
According to the author, the most prominent representative of personalism in Croatian catholic social thought is Bonifacije Perović, who, in several occasions starting in the 1930s, emphasises that not only personalism influenced Croatian catholic thougth but personalism was a kind of movement within the catholic social movement. Perović developes his critique of capitalism, marxism, formal democracy and searches for a new system with foundations rooted in the man and in the people. His work, pre- and postwar, was rounded in a trilogy on the present and the future of Croatian society where the starting point is a human beeing as a person
Test driven development in programming language PHP
No full textAgilni razvoj (eng. agile development) je metodologija razvoja softvera koja se sve više koristi. Temelji te metodologije bez kojih agilni razvoj nije moguć su: razvoj vođen testiranjem (eng. Test Driven Development - TDD), refaktoriranje (eng. refactoring), jednostavni dizajn (eng. simple design) i programiranje u paru (eng. pair programming). U ovom radu fokus je na razvoju vođenom testiranjem jer bez njega nije moguće ili je vrlo teško provoditi refaktoriranje, a bez refaktoriranja teško je postići jednostavni dizajn. Iako je fokus rada TDD, u radu su ukratko opisane i vezane discipline kao što su: refaktoriranje, uzorci dizajna, programiranje u paru i sl. Kako bi se programerima približilo način funkcioniranja TDD u praksi, dan je primjer korištenja TDD-a u razvoju jednog segmenta web aplikacije u programskom jeziku PHP. No bez obzira što se u primjerima koristi PHP koncepti TDD-a primjenjivi su na bilo kojem drugom programskom jeziku
Personalistička vizija čovjeka i hrvatskoga društva Bonifacija Perovića u vremenu od 1941. do 1979.
No full textThis paper examines the thought of Bonifacije Perović through three distinct periods of his life — during World War II (1941–1945), and during his life after having emigrated to Argentina (1947–1968) and then Italy (1968–1979). The author analyzes Perović’s work and doctrine based on the personalism, especially on the man as a person, battle against all totalitarian regimes, the primacy of the spiritual over the material, the economy in the favour of man and the priority of labor over capital. Perović was strongly influenced by Jacques Maritan, Emmanuel Mounier and Nikolai Berdyaev. Perović emphasized the centrality of person for philosophical thought and developed an entire doctrine of a person and Croatian society with a broad personalist’s view. These works make him the most prominent Croatian personalist thinkers.U ovom se radu istražuje misao Bonifacija Perovića nakon tridesetih godina prošlog stoljeća i to kroz tri razdoblja — tijekom Drugoga svjetskog rata (1941.–1945.), u emigraciji u Argentini (1947.–1968.) te u Italiji (1968.–1979.). Sagledavaju se i analiziraju njegova djela i nauk u svjetlu personalizma, filozofskoga pravca kojemu je središnji pojam osoba. Pri tome se osobito ukazuje na Perovićeve stavove o čovjeku kao osobi, borbi protiv totalitarnih režima, primatu duhovnog nad materijalnim, ekonomiji u službi čovjeka i prvenstvu rada nad kapitalom, iz kojih je vidljiv snažan utjecaj personalistā Jacquesa Maritaina, Emmanuela Mouniera i Nikolaja Berdjajeva. Kako je Bonifacije Perović izgradio cjelovit i opsežan nauk o čovjeku i hrvatskome društvu s personalističkih stajališta, zaključuje se da je Perović najizrazitiji hrvatski mislilac personalističkoga usmjerenja
Russian émigré thinkers and French personalism
No full textIzmeđu dva svjetska rata Pariz je postao središte umjetničkog, kulturnog i znanstvenog života, a ruski emigrantski mislioci i umjetnici značajno su tome pridonijeli. Pripadali su uglavnom personalizmu, filozofskom pravcu koji je rezultirao i stvaranjem više pokreta koji su pokušavali dati odgovore na složena onodobna kulturna, socijalna i filozofska pitanja. U radu se analiziraju pojam personalizma i njegova izvorišta, prikazuje se francuski personalizam i personalizam ruskih mislilaca te se ukazuje na njihove susrete i druženja. Iako je na francuske mislioce snažno utjecao neotomizam, a na ruske pravoslavna misao, naglašava se kompatibilnost i sličnost njihovih promišljanja, njihovo zajedničko djelovanje u razdoblju prije Drugoga svjetskog rata, koje je kasnije rezultiralo afirmacijom koncepta čovjeka kao osobe, ljudskog dostojanstva, ljudskih prava pa u konačnici i ujedinjenja Europe. Zaključuje se kako u ovom slučaju uspješno uključivanje emigranata u kulturni život nove postojbine i njihovo sinergijsko djelovanje znači i svojevrsni ekumenizam prije ekumenizma. Ostaje upitno koliko je personalistička misao, koja se može shvatiti kao simbioza neotomizma i ruske religijske misli, vratila kršćansku misao u središte europske misli, ali je nesporno da je zauzela značajno mjesto u suvremenoj raspravi o idejama.Between the two world wars, Paris turned into the center of artistic, cultural and scientific life, and Russian emigrant thinkers and artists contributed significantly to this. They belonged mainly to the personalism, a philosophical way which creation of several movements representing the common response to the complex questions of cultural, social and philosophical issues of the time. The paper analyzes the concept and sources of personalism, introduces the French and personalism of Russian thinkers and points to their encounters and socializing. Although French thinkers were strongly influenced by neotomism and Russian thinkers by Orthodox thought, the author emphasizes the compatibility and similarity of their thinking and chronicles their joint action in the period before the Second World War, which later resulted in the affirmation of the concept of a man as a person, human dignity, human rights, and ultimately the unification of Europe. The author concludes that in this particular case, the successful inclusion of emigrants in the cultural life of the new homeland and their synergistic action also signifies a kind of \u27ecumenism before ecumenism\u27. It is still ambiguous to what extent personalistic thought, presumed as a symbiosis of neotomism and Russian religious thought, has brought Christian thought back to the center european tought, but it is indisputable that it has taken a significant place in the contemporary discussion of ideas
