Komplexní řešení prodeje zboží / A Complex Solution for Selling Merchandise

Krhovský, Patrik January 2020 (has links)
The aim of this thesis is to analyze, design and implement solution for selling merchandise, which sellers can be used with commonly used hardware, free in basic package and they should be able to handle system setup. As a result, sellers can avoid new operating costs. The system will run as a service on Heroku servers. The front-end and back-end is implemented in JavaScript, front-end also uses React. GraphQL is used for communication between frontend and back-end. The data is stored in the PostgreSQL relational database, but also is used the Redis database, which runs tasks in the background.

Prestanda i en expanderande meddelandeorienterad arkitektur : En jämförande studie av Apache Kafka och RabbitMQ / Performance in an expanding message-oriented architecture : A comparative study of Apache Kafka and RabbitMQ

Svensson, Anton January 2021 (has links)
Människors levnadsstandarder förbättras ständigt tack vare nya innovativa system som möjliggörs genom att sensorer kopplas upp mot internet för att i realtid producera och analysera stora mängder viktiga data om den verkliga världens tillstånd. Luftkvalitet förvärras i världen och genom datainsamling och dataanalys kan realtidsvarningar erbjudas. Meddelandemäklare introduceras i systemarkitekturer för att samla in, lagra och strukturera datamängder på ett felsäkert sätt. Problemet är att meddelandemäklare måste kunna hantera många distribuerade luftkvalitetssensorer för att tillgodose behovet av exakt representation av luftkvalitet. Kafka och RabbitMQ sattes upp med hjälp av Docker för att under experiment undersöka vilken meddelandemäklare som tillhandahöll bäst prestanda när antalet sensorer ökade. En containeriserad webbapplikation utvecklades för att i ett gränssnitt kunna definiera exekverbara experiment. Containeriserade tjänster startades under exekvering upp. Genomsnittliga data aggregerades varje sekund till en mätpunkt för realtidspresentation i webbgränssnittet. Kafka tillhandahöll lägst latens och högst genomströmningshastighet när antalet sensorer ökade. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p>

MySQL och MongoDB operationer med Node.sj som ramverk / MySQL and MongoDB operations with Node.js used as framework

Zsambokrety Eliason, Adam January 2023 (has links)
Data används i stora mängder i dagens samhälle. Sjukvården är inget undantag och i den branschen kan analyser av data rädda liv eller uppfinna läkemedel. För att kunna bruka data i modern tid måste ett databassystem användas. Att välja rätt databassystem kan vara svårt och kräver att man vet varför man väljer den ena över den andra. Här jämförs två databaser för att generera data på om det skilljer sig mellan operationstiderna hos en relationsdatabas och en dokumentbaserad databas. Studien har valt att göra ett tekniskt experiment där MySQL brukas som relationsdatabas medans MongoDB används som dokumentbaserad databas. Node.js används som ramverk för att skapa applikationer där testning sker. Data är hämtad från U.S. Department of Health &amp; Human Services (2023) och representerar sjukvårdsdata från COVID. Operationstyperna INSERT och SELECT är de två som undersöks i denna studien. Resultatet bevisar att båda de framlagda hypoteserna stämmer. MongoDB var i båda testerna mer effektiv och producerade lägre operationstider för INSERT och SELECT. / <p>Stavningskorrigerad titel: MySQL och MongoDB operationer med Node.js som ramverk</p>

Using Web Technologies to adapt Data Visualizations for Mobile Devices : A use case in Eco Visualizations

Musliu, Arlind January 2016 (has links)
Visualizations, web technologies and mobile devices are subjects which are trending nowadays in the world of technology and many research projects are tackling different issues. The originality of the thesis is in the aspect of bringing all these mentioned subjects together and providing findings that will help web designers when implementing visualizations for mobile phones. The thesis explores the use of web technologies for the visualization of complex data for mobile devices, both looking at the technical state of the art and capabilities, and at the difference in information needs for users in a mobile usage context. The first part deals with an in-depth research of the existing projects that deal with similar issues, analyzing the official documentation of the technologies and the community of developers. The other part of the research is focused on providing insights on the required changes for adapting to the needs of mobile device users by doing a usability testing on a specific visualization. The results provide information valuable for adapting visualizations, such as font sizes, color combinations, animation complexity and data simplicity. The use case that is used for feeding the visualizations with data belongs to the domain of eco visualizations, in particular dealing with sustainable food consumption.

Peer-to-peer distribution of web content using WebRTC within a web browser

Ersson, Kerstin, Siri, Persson January 2015 (has links)
The aim of this project was to investigate if it is possible to host websites using the BitTorrent protocol, a protocol for distribution of data on the web. This was done using several Node.js modules, small clusters of code written in JavaScript, such as Browserify and a modified version of WebTorrent. In these modules, technologies like websockets and WebRTC are implemented. The project resulted in a working WebTorrent module, implemented on the website www.peerweb.io. However, the module still needs optimization concerning the time it takes to set up a WebRTC peer connection. With these modifications, we believe that hosting websites via peer-to-peer network will be the future of the web.

Přenos a zobrazení videa v prohlížeči pro záznam pracovní plochy / Processing and Streaming Video in Browser for Screen Recording

Svačina, Lukáš January 2016 (has links)
Aim of the thesis is to design and implement unique service based on the newest technologies in web apps fi eld which allows screen recording followed by P2P distribution between participating users using web browser only. Thesis deals with the analysis of modern and coming technologies which allow practical implementation of such a service. It involves obtaining access to the screen source data, its recording, transforming and transmission over the network followed by playing on the other side. Recorded videos are adapted for part by part use in a player with seeking capability. Distributed architecture for data exchange between peers using peer-to-peer connection based on hybrid P2P VoD network provides scalability of the solution. The player allows obtaining the necessary parts of the videos from the current watchers with smooth video playback experience during ongoing transmissions whilst allowing arbitrary video shifting. In consideration of early stages of development or experimental support for some of the APIs needed for this work, research into browsers' support with discussion on realistic applicability nowadays is always performed.

Herní engine pro ITIL trenažér / An ITIL Simulator Game Engine

Pučálka, Martin January 2018 (has links)
This master's thesis is focused on Information Technology Infrastructure Library (ITIL). Objective of the project was to analyze, design and implement a game engine, which would provide simulation of IT service operation in real or accelerated time or in turns. Basic part of the engine is a creators mode, which allows users to create custom IT services and specify their behaviour during operation, like the service would be used in real. Another part of the engine is a players mode and simple service desk. In this mode, players can take care of fluent operation of their services. Thanks to this, they can learn and train practices, which are described in ITIL.

Kryptografie a ochrana soukromí / Cryptography and Privacy Protection

Malík, Ondrej January 2021 (has links)
The main goal of this diploma thesis was to create web applications for issuer, verifier and revocation authority of revocable keyed-verification anonymous credentials system. Applications created in this thesis provide functions for all tasks, that are performed by each entity. Using these applications a global management of RKVAC system is possible. Authentication module created in verifier’s app is universaly usable for access control to any web service. Both issuer’s and revocation authority’s app are compatible with whole RKVAC system and are therefor applicable as central elements of systems.
