Item Praktikavõimalused IT-ettevõtetes Eestis tudengite ja ettevõtete perspektiivist: pilootuuring(Tartu Ülikool, 2020) Rist, Allan; Rozgonjuk, Dmitri, juhendaja; Paales, Mirjam, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutInformation technology is an important branch of the economy that has developed rapidly. The need for employees in the IT sector has risen faster than the educational system could adapt. During the research, students from the University of Tartu and companies which participated in a project called "Vali-IT" were questioned. The goal of the research was to study students' experience in an internship and companies' suggestions, experiences, and goals for internships. The present pilot study gathered input for the following research by collecting information about patterns, satisfaction, and suggestions from students and companies. Students' sample size was 125 of which 47 people had participated in an internship and their answers could be analysed. Companies' questionnaire was sent to 47 companies of which 7 responded. The results showed that the best-known internship was Playtech's. 20 (42%) students started working in the company they interned for, meanwhile only 7 (15%) students interned without a wage. The biggest expectation for students was to get hired and earn wages. 32 (68%) students found that interning increased their interest in the field. It appeared that COVID-19 had made organising an internship and being chosen as an intern more difficult compared to last year. Companies' main purpose in organising an internship was to recruit new employees. The results of the research brought attention to growth opportunities which could be made better. Although, before applying any changes, more research is needed.Item Eesti e-õpikute ülevaade(Tartu Ülikool, 2020) Pärkson, Ingrid; Feklistova, Lidia, juhendaja; Tartu Ülikool.

Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutProtein abundances and production rates differ by several orders of magnitude among protein-coding genes. We show that speci c protein abundances can be modeled as a function of mRNA abundances, translation efficiency and protein turnover. We then match RNA sequence motifs of 21 RBPs on the untranslated regions of 774 target transcripts. We determine that the RNA sequence motifs on target transcripts untranslated regions do not predict variability in translation efficiency of these transcripts. We use yeast Saccharomyces cerevisiae as the model organism.Item Blockchain Voting: A Systematic Literature Review(Tartu Ülikool, 2020) Dengo, Marianne; Milani, Fredrik P., juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutThe aim of the thesis is to study blockchain-based voting and its methods. In doing so, it is determined how blockchain-based voting works, which types of voting blockchain technology can be used for, and what are the advantages and disadvantages of doing so. A systematic literature review is carried out to study and compare different solutions. The purpose of the systematic literature review is to identify relevant research papers and use them to find and analyze different voting methods that utilize the blockchain. As a result, a framework is compiled summarizing the advantages, disadvantages, components, and possible areas of use of different solutions.Item Projekti “Household of the future virtual reality” arendus ja juhtimine Scrum meetodil COVID-19 pandeemia ajal(Tartu Ülikool, 2020) Kaljas, Hanna-Marii; Villems, Anne, juhendaja; Tartu Ülikool.

Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutThe feedback given by the students in Moodle to the course LTAT.03.001 Computer programming of the University of Tartu is very extensive. The collected data include start quiz, weekly quizzes, tests and final exam surveys. The answers are received in several different formats: single- or multiple-choice answers, a rating scale and free-form text. To analyze the feedbacks of years 2018 and 2019 a dedicated analysis environment was created. The analysis environment takes the survey data from several years as it input and creates a comprehensive summary of the answers to each survey question using various filters and calculation methods. The main part of the results is provided in the form of tables and figures. Free-form responses are processed using word clouds, where main problems and suggestions have been identified. As an end result the analysis environment creates a hundred different tables, figures and word pictures, which give a very good overview of the feedback of the whole course.Item A Systematic Review of Wireless Infrared Communication(Tartu Ülikool, 2020) Kruusi, Mihkel; Paršovs, Arnis, juhendaja; Morgan, Danielle Melissa, juhendaja; Tartu Ülikool.

The algorithm follows the style of the illustrations in the La mémoire de l'eau (Water Memory) graphic novel. Implementation is carried out in Maya Non-Photorealistic Rendering Framework (MNPR), which is a framework for the 3D computer graphics software Autodesk Maya. The devised algorithm consists of edge detection using difference of Gaussians for stylized lines and color smudging. The output of the devised algorithm is compared to the source material and potential future improvements are offered.Item Defining Business Process Models with Natural Language Processing and Speech Recognition(Tartu Ülikool, 2020) Balder, Karl Johannes; Maggi, Fabrizio Maria, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutProposed approaches for modeling unstructured business processes include declarative, constraint-based solutions, which meet halfway between support and flexibility. A noteworthy example is the Declare framework, which is equipped with a graphical declarative language whose semantics can be expressed with multiple logic-based formalisms. So far, the practical use of Declare constraints has been mostly hampered by the difficulty of modeling them: the formal notation of Declare represents a steep learning curve for users lacking an understanding of temporal logic, while the graphical notation has proven to be unintuitive. As such, this work presents and assesses an analysis toolkit which tries to circumvent this issue by providing the user with a possibility to model Declare constraints by using their own way of expression. The toolkit includes a Declare modeler supplied with a speech recognition mechanism, which accepts a user’s vocal statement as input and converts it into the closest Declare constraint(s) by combining voice recognition, natural language processing and business rule extraction technologies. The constraints cover the entire Multi-Perspective extension of Declare (MP-Declare), complementing control-flow constraints with data and temporal perspectives. Even though this thesis focuses on Declare, it represents the first attempt at testing the practicability of speech recognition in business process modeling altogether.Item KaiOS Application For Listening Podcasts(Tartu Ülikool, 2020) Arro, Fredi; Jaanuska, Ljubov, juhendaja; Tartu Ülikool.
