Statistics is defined as a scientific discipline based on learning from data and on finding, controlling, and presenting uncertainty. In these university textbooks we present the history of statistics, basic concepts of statistical modeling, measurement of dependencies, regression models, analysis of variance. We describe simple sorting, multiple comparisons, assumptions of the ANOVA model, Kruskal-Wallis test.

University textbooks are suitable for students of mathematics and computer science at the first and second level of universities. Study materials are also suitable for students of non-informatics disciplines with a view to improving their knowledge and practical experience in the fields of informatics and provide an opportunity for students to apply in IT companies in solving practical tasks.

Zriadenie cvičebne fyziológie rastlín na Katedre botaniky PF UPJŠ v Košiciach v roku 1969 bolo spojené s menom Ing. Štefana Kocúrika, CSc. (1923 - 2006), ktorý spracoval aj prvé „Návody na cvičenia z fyziológie rastlín“ (Košice 1972, 1976). Od roku 1980 sa využívala príručka doc. RNDr. Karola Erdelského, CSc. a Ing. Fridricha Friča, DrSc. „Praktikum a analytické metódy vo fyziológii rastlín“ (Bratislava 1980).
Po zvýšení počtu študentov, sa v roku 1991 ukázalo aktuálnym vydať „Návody na cvičenia z fyziológie rastlín“ v záujme lepšej prípravy a efektívnej organizácie práce na cvičeniach. Doc. RNDr. A. Košturiak, CSc. svojimi podnetnými radami prispel k podstatnému rozšíreniu úvodnej časti návodov, za čo sú mu autori zaviazaní vďakou.
Pre štvrté vydanie sme inovovali a modernizovali niektoré úlohy a zohľadnili sme možnosti inovovanej praktikárne. Výber úloh sme prispôsobili aktuálnemu rozsahu cvičení jednotlivých predmetov fyziológie rastlín v bakalárskych a magisterských študijných programoch biológie a ekológie. Ide o predmety: Fyziológia rastlín, Metabolizmus rastlín, Minerálna výživa rastlín, Rast a vývin rastlín a Ekológia rastlín. Niektoré úlohy sú vhodné tiež pre stredoškolské pokusy. Výber tém ovplyvnila výskumná orientácia nášho pracoviska na sekundárny metabolizmus, ekofyziológiu a liečivé rastliny. V návodoch sa spravidla pridržiavame jednotiek SI sústavy, niekedy uvádzame iné zaužívané jednotky.

The first chapter is devoted to the basics of domain theory, including the history of domain observation and the specification of different types of energies in ferromagnetic body. The second chapter presents the relationship between domain structure and magnetisation processes in ferromagnetic materials The third chapter describes the different types of domain-wall interactions with the defect. The fourth chapter illustrates examples of domain structure in selected ferromagnetic body such as grain oriented and non-grain oriented electrical steels, amorphous and nanocrystalline ribbons. The fifth chapter summarises an overview of the different experimental methods used to visualise the domain structure and their advantages or disadvantages with respect to the structure of ferromagnetic materials. The last two chapters, the sixth and the seventh, are devoted to specific experimental tasks for observing the domain structure of a selected polycrystalline sample using the optical microscope Bitter powder method and the MFM (magnetic force microscopy) method. During the preparation of this undergraduate text, its individual parts were developed using the foreign language literature listed in the recommended references.

The textbook is designed to prepare students who will engage in the experimental study of the properties of condensed matter. It demonstrates that a contemporary experimental physicist must not only possess sufficiently detailed knowledge of the physical processes occurring within the object under study but also understand the methods for creating the experimental conditions in which the experiment is conducted. Active knowledge of the functioning of the entire experimental setup can be of fundamental importance in the implementation or potential modification of the measurement methodology used.
