Artificial intelligence is increasingly transforming how students learn, including their approach to mathematics and problem-solving, by offering additional support and assistance—a trend that continues to attract research interest. One line of research focuses on helping students prepare for math competitions by solving more complex mathematical problems. In addition to regular national math competitions, which allow students to progress to international mathematical Olympiads, there are als...

U ovoj doktorskoj disertaciji definisani su i istraženi karakteristični re- peri duž krivih u prostorima Minkovskog. Uveden je Bišopov reper (reper sa svojstvom minimalne rotacije) pseudo nul krive i parcijalno nul krive u prostor- vremenu Minkovskog E41 . Izvedene su jednačine Bišopovog repera i dobijena je od- govarajuća relacija između Freneovog i Bišopovog repera. Pomoću geometrijske algebre prostor-vremena, određeni su Darbuovi bivektori Freneovog i Bišopovog repera pseudo nul kri...

У дисертацији су приказани резултати сопственог експерименталног истраживања три врсте биокомпозита који су засновани на млевеном окласку кукуруза, пиљевини и гранулама експандираног полистирена као агрегата док се као везиво користи мешавина креча и гипса. На предметним мешавинама испитани су одређени параметри као што су порозност, упијање воде, чврстоће при притиску и савијању, отпор протока ваздуха, коефицијент топлотне проводљивости, специфични топлотни капацитет и фактор отпора д...

The paper primarily dealt with the topic of forgiveness in Bernhard Schlink’s novel The Reader. Forgiveness has been discussed from the perspectives of the victims and the perpetrators. A multidisciplinary approach has been applied in the research, namely the moral philosophy has been applied to a particular literary work. The theoretical framework consisted of the following works: Forgiveness and Christian Ethics by Anthony Bash, On Cosmopolitanism and forgiveness by Jacques Derrida, Forgive...

La ricerca si concentra sull’analisi del trasferimento linguistico nella produzione scritta degli studenti che apprendono l’italiano come seconda lingua straniera e la cui prima lingua straniera è il francese o lo spagnolo. Gli aspetti chiave della ricerca riguardano gli errori fatti nelle produzioni scritte, ovvero i trasferimenti linguistici, che possono essere positivi, facilitando l’apprendimento grazie alle somiglianze tra le lingue, o negativi, causando errori a causa delle differenze l...

Using contrastive analysis, the paper compares the original meaning of Germanisms with their meaning in Serbian as the recipient language. The Germanisms were analysed from the point of view of the synchronic linguistic approach. Based on semantic criteria, the corpus was extracted from the Vukajlija Internet service, originally designed as a slang dictionary. The goal of the paper was to analyse the meaning of loanwords originating from the German language and their meaning in Serbian, as th...

Contemporary literature often classifies categorically diverse lexemes into adverbial intensifiers. The paper presents the results of independent corpus analyses of two languages. The largest available electronic corpora are used here: Corpus of Contemporary American English (COCA) and Korpus savremenog srpskog jezika 2013 (KSSJ). A semasiological approach is used to identify adverbs signifying (in)sufficiency of the degree expressed by comparatives and positives. The contrastive analyses exp...

Besides the modern non-metallic materials, which can successfully replace metallic materials in certain fields, steel materials are still largely present in technical practice. That trend will remain for many years to come. That is why there is a need to develop new types of steel, that possess better properties, in addition to the existing ones. The Cr-Mo steels, with a high vanadium content, belong to a group of newer steels with relatively high values of hardness and toughness. The X180CrM...

Simulation of concrete structures behavior is very popular in engineering design, as the concrete is the most used the material in the world. The possibilities are related to the development of Finite Element Method (FEM) based software and the possibility to implement advanced constitutive models or computational mechanics methods which can provide satisfying results. The most popular concrete constitutive model available in many FEM software is Concrete Damage Plasticity (CDP) model which t...
