Item Enesekontrolli- ja eksamitestid kursusele „Introduction to programming“(Tartu Ülikool, 2024) Joala, Kersti; Suviste, Reelika, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutThe University of Tartu course „Introduction to programming“ gives students their first knowledge about programming. The purpose of this bachelor's thesis was to create new selfassessment tests and exam tests for the course. A total of eight self-assessment tests and five exam tests were created. The direct feedback helps students to understand their mistakes, learn from their mistakes, and motivates them to improve their knowledge. Updating the tests reduces the probability that the questions and answers will spread among students. The selfassessment tests were created based on the ADDIE model for creating e-learning tools. The questions in the exam tests are similar to the questions in the self-assessment tests. The tests were created in Moodle and are in English. Students were asked to give free-form feedback to the self-assessment tests and it was largely positive. The feedback received from the students was that the self-assessment tests were helpful.Item Creation of Materials to Teach Data Science via Self-Driving(Tartu Ülikool, 2024) Kreegipuu, Artur; Tampuu, Ardi, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutAndmeteaduse projektides esineb tihti kitsaskohti, millega õpilased võivad olla teoreetiliselt tuttavad, kuid puuduvad praktiliselt kogemused. Sageli esinevaid probleeme saab demonst-reerida isejuhtivate mudelautode abil. Praktiliste ülesannete kaudu saavad õpilased kogeda, kuidas isejuhtivate närvivõrkude arendamise etapis tehtavad andmeteaduslikud vead mõju-tavad isejuhtiva mudeli sooritusvõimet. Lõputöö raames loodi isejuhtivate mudelautode abil praktilised õppematerjalid eesmärgiga panna õpilased mõistma, ära tundma ja ennetama andmeteaduses laialdaselt levinud probleeme. Selleks loodi probleeme demonstreerivad praktilised ülesanded, mille käigus tuleb õpilastel koguda andmeid, treenida isejuhtivaid närvivõrke ja katsetada loodud mudeleid rajal. Kõik ülesanded lahendati testimise eesmärgil erinevates valgusoludes ja iga ülesande eeldatud tulemist filmiti video. Loodud õppemater-jalidele koguti tagasisidet kahelt masinõppe eksperdilt.Item Veebipõhise Linuxi käsurea õppekeskkonna tootestamine(Tartu Ülikool, 2024) Eistre, Taavi; Peets, Alo, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkond; Tartu Ülikool. Arvutiteaduse instituutLinux and its command line are one of the main topics of the University of Tartu courses “Operating Systems” and “Computer Security”. In order to improve the ways of teaching Linux, Joonas Halapuu created a web-based Linux command-line learning environment prototype as part of his bachelor’s thesis in 2022. This prototype was used in the courses for a duration of two years. Several concerns about the stability and the need for further development of the learning environment emerged during its use. The aim of this thesis was to further develop, improve and migrate the existing environment to cloud technology to ensure better stability, scalability and accessibility. The thesis describes the shortcomings and potential enhancements of the previous environment, the requirements and objectives of the new application, the technologies used, the completed application and the results of testing the application in a cloud-based environment. The web-based Linux learning environment developed as part of the thesis can be found and used in Estonian or English at https://lingid.ee/kasurida.Item Veebirakenduse loomine ettevõttele Tööleidja(Tartu Ülikool, 2024) Leppik, Rando; Leping, Vambola, juhendaja; Tartu Ülikool.

Ajust mõõdetud andmete kontekstis see annab meile võimaluse saada erinevate stiimulite esindusi ajus ning võrrelda neid esindusi erinevate aju alade, erinevate loomuliikide ja erinevate modaalsuste vahel. Erinevate modaalsuste kaudu kogutud andmete võrdlemine on eriti raske neuroteaduse ülesanne sest see vajab meilt mingil viisil seostada neid moodalsusi omavahel, mis mõnikord võib olla ebatriviaalne ülesanne. Ajust kogutud andmete arvutusliku või käitumise mudelitega võib olla veelgi raskem. RSA tegeleb mainitud probleemidega. Üks küsimus mis tekkib on kui palju lineaarsed korrelatsioonid muutuvad pärast RSA kasutamist, mis on selles tööd uuritud. Meie vaatleme detailselt kuidas korrelatsioonid kahe algmassiivi vahel mõjutavad korrelatsioone vastavate esinduste vahel pärast RSA kasutamist. Tulemused näitavad, et kõigil juthudel järgu korrelatsioonid töödeldud andmetel on väiksem või samad kui lineaarsed korrelatsioonid algandmetes. See effekt on eritiv nähtav kui lineaarne korrelatsioon kuulub vahepealsete väärtuste hulka (0.3-0.6). Järeldus on see, et RSA hindab alla lineaarseid korrelatsioone algandmetes. Teistes sõnades, korrelatsioonid algandmetes on tavaliselt suurem või samad võrreldes RSA kaudu arvutatud korrelatsioonidega. Sellepärast, et mõned aju uuritused mis kasutavad RSA teevad järeldusi sõltuvuse struktuurist võrreldes arvutatud representatsioone, teadmine sellest, kuidas tegelik korrelatsioonide struktuur moonutatakse oleks väga kasulik. Laiemas perspektiivis, see võib mõjutada meie arusaamist sellest, mis on suur või väike korrelatsioon RSA kontekstis ning millal korrelatsioon on piisavalt märkimisväärne selleks, et järeldada et kaks andmete massiivi are omavahel sõltuvad.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.

The software provides the ability to process customer inquiries and manage contracts/agreements.Item Predicting Speci c Protein Abundances and Translation E ciency in Yeast(Tartu Ülikool, 2020) Kerner, Mark; Parts, Leopold, 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.
