Watching videos with subtitles in the original language is one of the most effective ways of learning a foreign language. Highlighting words at the moment they are pronounced helps to synchronize visual and auditory perception and increases learning efficiency. The method for aligning orthographic transcriptions to audio recordings is known as forced alignment. This work implements a tool for aligning transcript of YouTube videos with the speech in their audio recording, providing a web user interface with video player presenting the results. It integrates two state-of-the-art forced aligners based on Kaldi, first using standard HMM approach, second based on neural networks and compares their accuracy. Integrated aligners also provide a phone level alignment, which can be used for training statistical models in further speech recognition research. Work describes implementation and architectural concepts the tool is based on, which can be used in various software projects. 1

Applikationer kan idag med hjälp av olika tekniker utvecklas på flera olika sätt. På senare århar tekniken progressiva webbapplikationer blivit ett allt mer vanligt inslag i sammanhanget.Faktum är att progressiva webbapplikationer anses av många vara framtiden inomapplikationsutveckling. Det var dock otroligt svårt att hitta information om i vilkenutsträckning tekniken användes i Sverige eller i andra länder. Inför det här arbetet misstänktevi att tekniken med progressiva webbapplikationer inte användes i den utsträckning som denhade potential för , och att den förtjänade att uppmärksammas mer.I det här arbetet kommer du som läsare få en inblick i hur vanligt förekommandeprogressiva webbapplikationer var bland de svenska företagens hemsidor i allmänhet.Arbetet undersökte även vilka erfarenheter och kunskaper svenska applikationsutvecklarehade av tekniken. Ett antal intervjuer med svenska utvecklare har genomförts där resultatettalade för att det fanns mer att önska vad gällande utvecklarnas kunskaper och erfarenheterom tekniken. Indikationen om att de svenska utvecklarna hade begränsade kunskaper ocherfarenheter om progressiva webbapplikationer, återspeglades även i hur väl svenska företag iallmänhet använde tekniken. / Today, applications can be developed in a variety of ways using various techniques. In recentyears, the technology progressive web applications have become an increasingly commonfeature in this context. In fact, progressive web applications are considered by many to be thefuture of application development. However, it was incredibly difficult to find information onthe extent to which the technology was used in Sweden or in other countries. Prior to thiswork, we suspected that the technology of progressive web applications was not used to theextent that it had potential to, and it deserved to be paid more attention.In this thesis, you as a reader will gain an insight into how common progressive webapplications were among Swedish companies' websites in general. The work also examinedwhat experiences and knowledge Swedish application developers had of the technology. Anumber of interviews with Swedish developers were conducted where the results indicatedthat there was more to be desired regarding the developers' knowledge and experience aboutthe technology. The indication that Swedish developers had limited knowledge andexperience of progressive web applications was also reflected in how well Swedishcompanies generally used the technology.

Injektionsattack är den mest kritiska säkerhetsapplikationen för webbapplikationer, och SQL-injektion (SQLi) -attack är den mest rapporterade injektionsattacken på webbapplikationer. I denna avhandling har vi identifierat angreppsteknikerna som används av angripare och vi ger också riktlinjer så att programmerarna kan skriva webbapplikationskoder på ett säkert sätt för att förhindra SQLi-attackerna.Metoden som tillämpas för forskningen är litteraturstudie och vi använde vägen bevis genom demonstration för att få den tydliga bilden. Det första steget var att ta reda på kodningsfelen, då utformade vi riktlinjer som kan hjälpa till att skydda webbapplikationer från SQLi-attacker. Denna avhandling kommer att hjälpa programmerarna att förstå de olika kodningsbristerna och hur dessa kodningsfel kan förhindras och för detta har vi använt bevis genom demonstration. Denna avhandling kommer också att bidra till den allmänna medvetenheten om SQLi-attacker, attacker och riktlinjer för programmerare som designar, utvecklar och testar webbapplikationer. / Injection attack is the most critical web application security risk, and SQL-injection (SQLi) attack is the most reported injection attack on web applications. In this thesis, we have identified the attacking techniques used by attackers and we are also providing guidelines so that the programmers can write web application code in a secure way, to prevent the SQLi attacks.The methodology applied for the research is literature study and we used the way proof by demonstration to get the clear picture. The first step was to find out the coding flaws, then we designed guidelines that can help to protect web applications from SQLi attacks. This thesis will help the programmers to understand the various coding flaws and how those coding flaws can be prevented and for this, we have used proof by demonstration. This thesis will also contribute to the general awareness of SQLi attacks, attack types and guidelines for the programmers who are designing, developing and testing web applications.

Migration av data innebär att data flyttas från en databas till en annan. Denna åtgärd kan företag behöva av olika skäl, till exempel för att ändra språk eller förnya befintlig databas. Något som diskuteras är hur denna process ska ske och hur data migreras på bästa smidigaste sätt. Ett av IT företagen som var i behov av svaren är XLENT Sundsvall. XLENT har en webbshop där gränssnittet är föråldrat, samt i behov av en bättre serverlösning ur ett förvaltningsperspektiv. Den här studien syftar till att se över möjligheterna att flytta över den befintliga hemsidan till en modern e-handelslösning. Titta på vilket bästa sätt är att migrera datan till en ny databas som är mer lämplig för hemsidan. De metoderna som ska jämföras är en export-import möjlighet och Extract Transform Load ( ETL) verktyg. Export-import metoden visade sig vara den mest lämpade processen för en databas med våra egenskaper, och en migration med valda processen genomfördes. Till migrationsprocessen hör även städning av data. Ett viktigt steg då databasen bestod av redundant data. En jämförelse mellan den nya och gamla databasen visade att städningen vara en lyckad process då den redundanta datan reducerades med 24 procent. Export-import processen valdes då metoden passade bäst för databas egenskaperna. Då databasen hade varit mycket större eller vara skrivet i ett annat SQL språk så vore metoden inte helt optimalt längre. Då skulle ETL verktyget vara med önskvärt. Vid fortsatt arbete så skulle det vara intressant att göra en mer teoretisk jämförelse. Testa att migrera på de olika sätten, med databaser med olika egenskaper för att få en mer övergripande blick av vilken som passar bäst i olika fall. / Data migration means the transfer of data from one database to another. This is something that more and more companies need to do. for various reasons, for example to change the language or renew the existing database. Something that is discussed is how this process should take place and how data is migrated in the best and most flexible way. One of the IT companies that was in need of the answers is XLENT Sundsvall. XLENT has an online shop where the interface is outdated, and in need of a better server solution from a management perspective. This study aims to review the possibilities of moving over the existing website to a more modern solution. Look at the best way to migrate the data to a new database that is more suitable for the website. The methods to be compared are an export-import method and Extract Transform Load (ETL) tool. The export-import method proved to be the most suitable process for a database with our properties, and a migration with the selected process was performed. The migration process also includes cleaning of data. An important step as the database consisted of redundant data. A comparison between the new and old databases showed that cleaning was a successful process as the redundant data was reduced by 24 percent. The export-import process was chosen as the method best suited the characteristics of the existing database. With a database being much larger or being written in another SQL language, it might not be the most optimal solution anymore. Then the the ETL tool would be better. With continued work, it would be interesting to make more than a theoretical comparison. Try migrating with many different databases with different properties to get a more comprehensive look of which one is best suited in different cases.
