In 2018, the Student Scientific Conference was held on April 18, 2018, in 16 sections covering biology and ecology, chemistry, physics, geography, mathematics, computer science, and their subject didactics. There were 110 registered contributions from bachelor's and master's students. Additionally, eight high school students participated outside of the competition; these students already visit our alma mater at a young age, work in our laboratories, and prepare for further studies under the guidance of our enthusiastic teachers. The day also included a programming competition and the IHRA competition in three categories, where students from PF UPJŠ competed alongside pupils from elementary and secondary schools.

The abstracts of the Student Scientific Conference contributions convincingly demonstrate that PF UPJŠ students study their field not only theoretically but also actively engage in solving partial scientific problems that are part of the research goals at PF UPJŠ institutes. This collection provides an overview of scientific activity at the faculty, which we believe will be interesting for the broader public as well.

V tomto učebnom texte sú spracované základy fenomenologickej termodynamiky v rozsahu, ktorý je prednášaný v štandardných kurzoch teoretickej fyziky na bakalárskom stupni študijného programu Fyzika. Mierne zredukovaný rozsah sa prednáša tiež na všetkých medziodborových študijných programoch v kombinácii s fyzikou. Časová dotácia pre jednotlivé kurzy bola v posledných rokoch mierne zredukovaná, čomu zodpovedá náš výber a rozsah jednotlivých tém. Našou primárnou snahou bolo dostatočne fundovane vysvetliť kľúčové pojmy a zákony termodynamiky, ktoré sú nutné pre zvládnutie ďalších teoretických fyzikálnych kurzov na magisterskom stupni štúdia (napr. Štatistická fyzika, Fyzika kondenzovaných látok, Kvantová teória tuhých látok, Kvantová teória magnetizmu atp.). Kniha tiež prestavuje nutné minimum vedomostí, ktoré sú nevyhnutné pre štúdium ďalších aplikácií termodynamiky v biofyzike, biológii, chémii, prípadne v inžinierskych odboroch. Porozumenie jednotlivých častí, ale aj textu ako celku vyžaduje ovládanie základných pojmov termodynamiky na úrovni kurzu Všeobecnej fyziky a znalosti v rozsahu štandardného univerzitného kurzu matematiky. Jednotlivé témy sú spracované s maximálnym dôrazom na koncepčnosť a matematickú rigoróznosť. Tak ako v iných teoretických disciplínach, aj v termodynamike vyžaduje pochopenie kľúčových pojmov a zákonov paralelné riešenie praktických úloh k jednotlivým témam, čo sa prirodzene deje na numerických cvičeniach, ktoré sú súčasťou kurzu. Pre čitateľov, ktorí nie sú univerzitnými študentami odporúčame ako cvičebnicu knihu R. Kubo: Thermodynamics, North Holland Publishing Company (1968). Tak ako každá kniha, aj tento text nie je dokonalý a určite sa v ňom nájdu nedostatky rôzneho charakteru. Budeme preto vďační každému čitateľovi za konštruktívne obsahové i formálne pripomienky. Na záver chceme poďakovať Janke Jaščurovej za jazykové korekcie a Ing. Mgr. Viliamovi Štubňovi za technickú podporu pri spracovaní obázkov v tomto učebnom texte a tiež za korekcie textu.

Machine learning addresses the issues of how computer programs recognize complex patterns and make decisions based on data. In these university textbooks, we focus on theoretical knowledge in the field of machine learning in which we present the creation of concepts for objects, the preparation of concepts, hypotheses and the process of learning from examples. We describe Boolean formulas and their representations, probabilistic learning, linear and logistic regression, linear modeling and classification. Clustering and the Bayesian approach to machine learning conclude this publication.

University textbooks are intended for students of master's degree programs in computer science.

Organic chemistry is the chemistry of carbon. Organic compounds in the form of large molecules (macromolecules), such as nucleic acids, proteins, carbohydrates, and lipids are the basic elements of living organisms. This study material is created for non-chemistry students, especially students of biology. Most of these students have little or no knowledge of organic chemistry. Therefore, we proceed from the basic principles of organic chemistry to biochemistry.

The basic principles of organic chemistry and biochemistry are briefly summarized in individual chapters, but the main content consists of tasks for practising basic knowledge. To check the correctness of solving the tasks, the correct solutions are also given. The importance of this study material lies in the fact that students will get additional study material that they will use in studying the subject Basics of Chemistry.

The structure of the animal body is extremely varied. Each species has its distinctive morphological features, which bears as a testimony to long-term development and belonging to the developmental lineage. At the same time, the body has been tested for a long time by natural conditions, resulting in unique adaptations to the environment and life strategy. Despite this admirable variety - which includes both recent and fossil animals and which we have far from mapped – a comparison of body parts brings knowledge we can generalize: the main building principles, and boundaries within which phenotypic diversity is realized.

Comparative animal morphology today uses the latest methodological material and knowledge from other disciplines, from genetics, molecular biology and experimental embryology, through progressive imaging methods (e.g. electron microscopy, computer micro-tomography) and the possibilities of subsequent software processing of image material (measurement, staining, etc.) to the view of physics, chemistry, statics and geometry on the structures (to nanostructures) of the living body. Detailed knowledge of historical and contemporary conditions on Earth is an important interpretative context in the study of animal morphology. Surprisingly, the knowledge accumulated after centuries of research is now rapidly supplemented by new knowledge, and often the traditional knowledge is subsequently reinterpreted. Finally, and no less important, in studying animal (and human) morphology, we learn surprising knowledge about ourselves.

The author of the presented textbook had the ambition in a simplified form to introduce the reader, especially the student of biological studies, into a dynamic and fascinating scientific discipline, as the current comparative animal morphology is.

The present textbook deals with exactly solved models and their diverse applications in several branches of physics such as mathematical physics, statistical physics, condensed matter physics and so on. Exactly soluble models are currently considered as an inspiring research field in its own right, which regrettably requires a considerable knowledge of sophisticated mathematics. Accordingly, my primary ambition was to provide an intro- ductory course for undergraduate students that would cover the simplest exactly solved models, whose rigorous solutions are available even after modest calculation. The present textbook should be therefore regarded as an auxiliary graduate-level textbook, which should serve as the student’s guide on this beautiful but surely intricate subject.

Even although I attempted to write largely self-contained textbook for undergraduate students, it is worthy of notice that the course on Exactly Solvable Models in Statistical Physics demands essential knowledges from the quantum mechanics, statistical physics, phase transitions and critical phenomena, which are its indispensable prerequisities. The most crucial fundamentals of these theories are briefly recalled in introductory remarks just for remembering and not for substituting those comprehensive courses. The rest of this textbook is entirely devoted to exactly solved lattice-statistical models with the main emphasis laid on their possible applications in the condensed matter physics. It is the author’s hope that the presented exact solutions are detailed enough in order to be easily followed by undergraduate students even without a support of tedious proofs, cumbersome theorems, longer argumentations, or obvious facts. This rather necessary compromise has of course a certain unadvisable impact on ’exactness’ of the presented solutions.

Finally, it is worthwhile to remark that the present textbook makes just a slight introduction into the simplest exactly solvable models and thus, the interested reader is referred for the follow-up study to several excellent books on exactly solved models quoted in the bibliography list on the next page. Note that the listed books were the major knowledge sources used by creating this textbook and they might be regarded as more advanced literature on this exciting research field.

In the presented university textbooks, so-called satellite-based augmentation systems (SBAS, from the English Satellite Based Augmentation Systems, in Slovak Systémy rozširujúce základné satelitné systémy) are also discussed. These systems enhance, expand, or refine the basic satellite navigation systems. They are supportive satellite systems for GNSS (Global Navigation Satellite Systems). Currently, the long-operational American GPS and Russian GLONASS systems, as well as the partially operational European Galileo system (since December 2016), have and will continue to have broad applications in various fields of human activity, both professional and personal.

The university textbook Globálne navigačné satelitné systémy (Global Navigation Satellite Systems) reflects the current progressive development in the technological and instrumental principles and components of such satellite navigation systems. It presents the state of these satellite technologies from their historical origins and development to the present. The rapid advancements, particularly in the instrumental base of satellite navigation systems, will require updates on their current state in future editions of these university textbooks.
