The project described in this report aims to construct a web interface for a multi-purpose transmitter (MPT). The MPT is a submodule that is meant to be used in future chromatography systems. This bachelor thesis project is done at Cytiva in Uppsala. The MPT uses the Azure RTOS development suite with ThreadX as the RTOS, FileX as the file system, and NetX for the TCP/IP protocol stack implementation. The Azure RTOS platform facilitates development for deeply embedded systems and comes with extensive documentation for their services. The web interface consists of 5 web pages with 5 different use cases: Overview for visualization of basic data; Data for visualization, recording, and filtering of all data; Update page for firmware update and file management; Log for development logging purposes; and Config for modifying parameters and running module diagnostic tests. Development of the front end was done in Visual Studio Code. The workflow was streamlined by developing a tool at the beginning of the project that combines the files for the front-end code into variables stored in C source files. Testing of new features was aided by a Python Flask server developed in parallel to the main back end. It embodies the same functionality as the main back end, aside from being hosted on a local computer. The web interface will mainly be used by customers and service personnel. This requires the interface to have two different access levels. The Overview page can be accessed without any authorization while the other pages require the user to be authenticated via username and password. / Vid tillverkning och forskning inom Life Science krävs det väldigt noggranna och välkalibrerade instrument. Dessa instrument behöver också underhållas, dels då de riskerar att gå sönder och för att säkerställa att de är korrekt kalibrerade. För att underlätta servicearbetet av Life Science-instrument har vi i detta projekt utvecklat ett webbgränssnitt.Ett webbgränssnitt är en hemsida som är möjlig att nå i en webbläsare för att kunna interagera med en modul. Arbetet har utförts på Cytiva, som är ett världsledande företag inom Life Science. Projektet består till viss del av utvärdering av alternativa lösningar, detta inkluderar val av dataformat, kommunikationsprotokoll, bibliotek, ramverk och metod för datauppdatering. Denna utvärdering baserades huvudsakligen på följande aspekter: minnesavtryck, robusthet och prestanda. Webbservern är skriven i programmeringsspråket C och använder sig av utvecklingsplatformen Azure RTOS. Det innehåller ett realtidsoperativsystem ThreadX, ett filhanteringssystem FileX och en nätverksstack NetX.  För att lättare kunna testa uppdateringar skapade vi en utvecklingsserver parallellt med vår webbserver i C. Denna server är skriven i Python med hjälp av ramverket Flask. Den har samma funktionalitet som MPT webbservern och kan köras lokalt på datorn.  Slutliga webbgränssnittet har fem olika sidor med fem olika funktioner: Overview för att visualisera grundläggande data, Data för att visualisera och filtrera all data på modulen, Update för filhantering och för att kunna uppdatera modulens mjukvara, Log för loggning vid utveckling och slutligen Config för att kunna justera parametrar och utföra diagnostik på modulen. Det som visas i webbläsaren, front end, är skrivet i programmeringsspråken HTML, CSS och JavaScript. Användandet av ramverk och bibliotek utvärderades men slutsatsen av det är att behovet för det inte övervägde ökningen i minnesavtryck. Koderna från de olika språken vävdes samman med hjälp av ett verktyg som utvecklades för att underlätta skapandet av gränssnittet. Verktyget är skrivet i Python och gör utvecklingen både snabbare och enklare genom att möjliggöra front-end utveckling i programutvecklingsmiljön Visual Studio Code.

Disasters are characterized by large numbers of victims and required resources, overwhelming the available resources. Disaster response involves various entities like Incident Commanders, dispatch centers, emergency operations centers, area command and hospitals. An effective emergency response system should facilitate coordination between these various entities. Victim triage, emergency resource allocation and victim dispatch to hospitals form an important part of an emergency response system. In this present research effort, an emergency response system with the aforementioned components is developed. Triage is the process of prioritizing mass casualty victims based on severity of injuries. The system presented in this thesis is a low-cost victim triage system with RFID tags that aggregate all victim information within a database. It will allow first responders' movements to be tracked using GPS. A web-based real time resource allocation tool that can assist the Incident Commanders in resource allocation and transportation for multiple simultaneous incidents has been developed. This tool ensures that high priority resources at emergency sites are received in least possible time. This web-based tool also computes the patient dispatch schedule from each disaster site to each hospital. Patients are allocated to nearest hospitals with available medical facilities. This tool can also assist resource managers in emergency resource planning by computing the time taken to receive required resources from the nearest depots using Google Maps. These web-based tools complements emergency response systems by providing decision-making capabilities.

The Pier Portal marine monitoring system is an internet controlled underwater camera that will enable students, researchers, and the general public the ability to monitor underwater marine life and ocean conditions. Installed at Cal Poly’s Center for Coastal Marine Science pier at Avila Beach, California, the camera can be commanded in real-time to raise or lower to any position between the top of the pier and the bottom of the ocean floor, while providing a live-stream video to the operator and general public. This thesis effort focused on the integration of the various subsystem components through software, and the development of an online interface to allow the remote control of the system and the ability to view the live-stream video from the camera. Missing or damaged mechanical and electrical components were successfully redesigned and replaced, and a more compact and serviceable winch and sheave system was designed and partially manufactured. A software set was written in Python, JavaScript, HTML, and IEC 61131-6 successfully connecting the system’s control server, the winch’s industrial PLC, the cameras inside the underwater pod, and the front-facing webserver. The system’s internal network has been designed to allow internal components to communicate, and to allow external users the ability to securely control the system and view the video feed. Due to campus closure in early 2020, the final system was unable to be installed and tested, however, this document contains the entire system design and the next steps required to fully implement the system.

This thesis investigates the issues of creating a publicly accessible Web interface to a remote autonomous robot: the Bradford Robotic Telescope. The robot is situated on Mount Teide, on the island of Tenerife, Spain. Its mission is to provide interactive access to the stars to people who would otherwise not be able to appreciate the wonders of the night sky due to light pollution. Whenever weather and darkness permits, the robot processes the observation requests submitted by users via the Internet, operating all the hardware including the dome, telescope mount and cameras. The question of how to enable a content rich high quality dialogue between one robot and thousands of users is explored and divided into seven areas of research. How to design a Web site enabling high quality interaction with the user, how to enable users to request service from a robot, how to store and manage all the user and robot generated data, how to enable communication between the Web interface and the robot, how to schedule many observation requests in the best order, how to support a constant dialogue between the robot and users to engage users in the robot's work, and how to present and display users' completed observations. These seven areas of research are investigated; solutions are presented and their implementations examined and evaluated for their suitability and performance with the Bradford Robotic Telescope, and for how they might perform for any job-based remote robot.

Atualmente, a forma mais usual de comunicação direta entre as organizações e seus (possíveis) clientes é através de aplicações baseadas na Web. Entre as vantagens deste tipo de aplicação estão a disponibilidade em tempo integral (24/7/365) e a facilidade de acesso, tendo em vista que o requisito inicial é apenas um computador com acesso à Internet. No contexto da disciplina de Engenharia de Software, as aplicações Web possuem características específicas que as diferem de aplicações tradicionais, especialmente no que se refere à interação com os usuários, e que devem ser consideradas adequadamente no processo de desenvolvimento. Entretanto, os processos de software tradicionais são dirigidos à funcionalidade e a parte do sistema responsável pela interação com os usuários é tratada com menor ênfase usualmente apenas na etapa de Implementação, ocasionando deficiências no produto e insatisfação dos usuários quanto ao uso do sistema. Neste cenário, este trabalho apresenta o método WE4UIV (Web Engineering User Interaction View), dirigido a modelos e baseado em componentes, cujo propósito é tratar os aspectos relacionados à visão de interação com os usuários de aplicações Web, nos níveis de análise e projeto, de modo a fornecer subsídios para orientar a etapa de Implementação. Além disso, visando acelerar e tornar menos manual a etapa de Implementação, este trabalho também apresenta uma ferramenta integrada a um ambiente de desenvolvimento para geração de código fonte a partir de artefatos de projeto descritos em UML. A abordagem apresentada neste trabalho pressupõe melhorias quantitativas no processo de desenvolvimento da visão de interação com os usuários, especificamente redução do tempo da etapa de Implementação e do índice de trabalho adicional causado por solicitações de mudança. A abordagem proposta é validada através de um processo de experimentação no contexto de um projeto real de desenvolvimento de software

The purpose of this study is to explore the representation of national political freedom on web interface design by using power distance, one of the culture dimensions identified by Geert Hofstede, as a measurement. This study also aims to determine if there are any differences between government-based websites and business-oriented websites in representing national political freedom. A pilot study was conducted to validate ten power distance indicators identified from previous research on cultural dimensions with the intent of establishing a measurement for determining a country's national political freedom on web content and interface design. The result showed that six out of ten proposed indicators are valid power distance indicators. The seventh indicator, symmetric layout, demonstrated that its Web representation correlates with national political freedom level. Consequently, the principal research applied these seven indicators in coding 312 websites selected from 39 countries and analyzed national political freedom represented on these websites with content analysis method. The result of two-way analysis of variance (ANOVA) indicated that large differences exist in web interface design, which in turn reflects the aforementioned national political freedom. The research showed that the mean effect of freedom level between free-country group, partly-free-country group and not-free-country group was statistically significant (p = .003). So was the mean effect of website type between government-based and business-oriented websites (p = .000). Furthermore, the interaction between the freedom level and website type was also significant (p = .041). Therefore, we conclude that web interface design represents a country's political freedom and government-based websites embody more of a nation's authority and supremacy than business-oriented websites do. It is expected that this study furthers our exploration in culture dimensions on web interface design and advances our knowledge in sociological and cultural studies of the web.

In the age of Big data and exponential digitalization, data visualization is becoming a ubiquitous tool to understand trends, patterns and identify deviations that better help in decision making. The purpose of this thesis is to explore how a scalable data visualization interface can be designed with the open-source web library D3.js. The interface is designed to display a range of patients’ physiological measurements to help healthcare professionals with Covid-19 diagnosis. Several prerequisites were identified through a qualitative study, which proved to alleviate the implementation process, such as choosing a robust model that can support visualizations despite discontinuous and incomplete datasets. Since faulty visualizations may lead to potential harm in the highly sensitive medical setting, a dedicated risk analysis was deemed beneficial and thus formulated. The design of the interface also revealed functionality that could be considered when implementing any visualization interface, such as the rendering of different views and features that can further assist the user in interpreting the visualizations. / I en tid med Big Data och en exponentiellt växande digitalisering, blir datavisualisering ett mer förekommande verktyg för att förstå trender, mönster och identifiera avvikelser för att underlätta beslutsfattande. Syftet med studien är att utforska hur ett skalbart datavisualiseringsgränssnitt kan utformas med hjälp av det webbaserade biblioteket D3.js. Gränssnittet är utformat för att visa ett omfång av patienters fysiologiska mätvärden med syftet att hjälpa sjukvårdspersonal med diagnostiken av Covid-19. Flera förutsättningar kunde upptäckas med hjälp av en kvalitativ förstudie. Denna studie visade sig underlätta implementeringsprocessen, där bland annat en robust modell som stödjer visualiseringar trots diskontinuerliga och ofullständiga dataserier identifierades. Eftersom felaktiga, eller delvis fungerande visualiseringar kan leda till potentiell skada i den mycket känsliga medicinska miljön, ansågs en riskanalys vara fördelaktig. Därför utformades en sådan analys, som dessutom visade sig sedan kunna vara användbar i flera sammanhang. Gränssnittets design visade också på gemensam funktionalitet som kan övervägas vid implementeringen av andra visualiseringsgränssnitt, bland annat hur vyer renderas men även funktioner som vägleder användaren till att lättare kunna tolka de olika visualiseringarna.
