Development of a location-based taxi service : using open-source tools

Maechel, Lars January 2016 (has links)
The aim of this project is to develop a component able to retrieve taxi providers in Sweden, based on input of coordinates and a search radius. The result should be available in a well-structured and accessible way through an RESTful web service. The study is conducted based on a customer inquiry stating that the component should be built using open-source tools and be developed in such a way that allows the component, or parts of the component, to be integrated in a larger system. Therefore, a preliminary study was conducted in order to find suitable open-source tools that are able to solve the specific customer requirements. The component uses an ad hoc company search engine to retrieve the taxi providers, contact information and coordinates. Additional information needed for determining the correctness of the taxi providers are retrieved from external resources and a filtering process is then performed before they are saved in persistent store. The project is successful in solving the main purpose and most of the customer requirements, while the RESTful service is unable too fully meet the requirement stating that the component should be able to handle multiple concurrent clients while still maintain responsiveness. This, is mainly due to the decision not to use an ad hoc framework in handling geospatial data structures and calculations and was a trade-off to ensure re-usability and integration of the component in a larger system. / Avsikten med denna studie är att bygga en komponent som kan returnera taxiföretag i Sverige baserat på koordinater och en sökradie. Resultatet skall presenteras för användare eller andra tjänster på ett välstrukturerat och tillgängligt sätt via en RESTbaserat webbtjänst. Projektet är ett resultat av en kundförfrågan i vilken det även specificeras att komponenten skall använda sig av data eller verktyg som är fritt tillgängliga och att den skall vara byggd på ett sådant sätt att det går att använda hela, eller delar av, komponenten i ett större system. En kortare förstudie genomfördes med syfte att hitta lämpliga verktyg som bygger på öppen källkod för att lösa de specifika krav kunden ställt på komponenten. Komponenten använder sig av en sökmotor för företag-sök där resultaten görs tillgängliga via ett RESTbaserat API. Varje företag genomgår sedan en filtreringsprocess innan de sparas i databas för att avgöra om det uppfyller de kriterier som är uppsatta. Denna filtrering baseras på information som inhämtats genom en automatiserad process. Denna studie har varit framgångsrik i avseendet att bygga en komponent som kan returnera företag inom ett visst område baserat på koordinater och en given sökradie. Den uppfyller även de allra flesta av de krav kunden har satt upp, med undantag för det krav som efterfrågar en responsiv hantering av många samtidiga användare. Detta beror främst på valet att inte använda sig av ett ramverk avsett för hantering av geospatial data. Detta var en avvägning som gjordes för att försäkra sig om att komponenten skulle vara återanvändbar i ett större system.

Load profiling and customer segmentation for demand-side management

Baril, Anne January 2023 (has links)
The energy transition is accompanied by massive electrification of uses and sectors such as transport. As a result, the pressure on the electricity grid is increasing, and the time to connect to the power system is lengthening. Deploying new infrastructure is a laborious and expensive process but there are alternatives to exploit the flexibility of the power grid. The deployment of smart meters opens the door to many applications related to flexibility on the consumer side, to reduce peak loads that threaten grid capacity. Targeting the right consumers for Demand-Side Management (DSM) is a prerequisite to maximizing the chances of success of such programs. This degree project replicates and adapts the method developed in [14] to segment residential customers. It consists of encoding Daily Load Curves (DLC) using a dictionary of Typical Load Profiles (TLP) and grouping consumers according to the distribution of their TLP. A temporal analysis of the main TLP reveals different consumption behaviors. Customers are segmented into groups that reflect the degree of volatility of their consumption. This enables a classification based on the potential for Energy Efficiency (EE) or Demand Response (D/R) programs. We address the issue of attribute detection using the distribution of TLP of customers. In particular, several classification algorithms are compared to detect TLP characteristic of Electric Vehicle (EV). The obtained load shapes show consumption peaks at night, which may correspond to the charging time of EV. The method is discussed, especially the choice of the number of load profiles to be included in the dictionary of TLP. It proves to be useful to group consumers with similar consumption profiles and opens the door to applications such as individual household consumption forecasting. / Energiomställningen kräver en massiv elektrifiering av användningsområden och sektorer som t.ex. transportsektorn. Detta leder till att trycket på elnätet ökar och att tiden för att ansluta sig till elnätet blir allt längre. Att bygga ut ny infrastruktur är en mödosam och dyr process, men det finns alternativ för att utnyttja elnätets flexibilitet. Utplaceringen av smarta mätare öppnar dörren för många tillämpningar som rör flexibilitet på konsumentsidan, för att minska toppbelastningar som hotar nätkapaciteten. Att rikta in sig på rätt konsumenter för DSM är en förutsättning för att maximera chanserna att lyckas med sådana program. I detta examensarbete replikeras och anpassas den metod som utvecklats i [14] för att segmentera hushållskunder. Den består av att koda DLC med hjälp av ett lexikon av TLP och gruppera konsumenter enligt fördelningen av deras TLP. En tidsmässig analys av de viktigaste TLP avslöjar olika konsumtionsbeteenden. Kunderna delas in i grupper som återspeglar graden av volatilitet i deras konsumtion. Detta möjliggör en klassificering baserad på potentialen för EE eller D/R-program. Vi tar upp frågan om attributdetektering med hjälp av fördelningen av TLP hos kunderna. I synnerhet jämförs flera klassificeringsalgoritmer för att upptäcka TLP som är karakteristiska för EV. De erhållna belastningsformerna visar konsumtionstoppar på natten, vilket kan motsvara laddningstiden för EV. Metoden diskuteras, särskilt valet av antalet belastningsprofiler som ska ingå i ordlistan för TLP. Metoden visar sig vara användbar för att gruppera konsumenter med liknande förbrukningsprofiler och öppnar dörren för tillämpningar som prognostisering av enskilda hushålls förbrukning.

Extramural English Activities in the Swedish ESL Classroom / Fritidsengelska  i engelska undervisningen

Aychan, Ibrahim January 2021 (has links)
This literature review explores the use of Extramural English in the classroom and its effects on students’ language acquisition. Through a systematic analysis of different studies on EE activities such as video games, the Internet, gaming, and other activities, this paper will investigate the possible positive or negative effects of EE activities on students’ performance. The results of this literature review show that students who are more exposed to EE activities have a better result with regard to the acquisition of English than their peers because the language of communication in Extramural activities is mainly English.  The results also show that by incorporating EE in the classroom, teachers will be able to define the student’s strengths and weaknesses through eliciting the learning evidence when learning English as a second language.

Implementing a telemedicine system for remote medical consultation

Enlund, Simon, Jourkovski, Alexander January 2016 (has links)
Telemedicine is the combination of information technology (IT) and health care and is an area that has seen increase during the last few decades due to breakthroughs in IT. Today there are still parts of the health care system that can be counterproductive with regards to the time and commitment necessary. One such part is medical consultations for private individuals where many of the simpler ones are still carried out in-person. Presented in this thesis is the implementation of a prototype telemedicine system that could be used as a substitute for in-person doctor-patient consultation. Necessary 3rd party components and their implementations into one system are described on a general use level. The result is a web application that supports login and payment via trusted sources, booking of meetings and carrying them out with video and audio. The prototype is a continuation of a telemedicine web application idea that was put on ice by a company that already provides solutions for health controls and blood analysis. / Telemedicin är kombinationen av informationsteknik (IT) och hälsovård och är ett område som har sett en ökning de senaste årtiondena på grund av genombrott inom IT. Idag finns det fortfarande delar av hälsovården som kan vara kontraproduktiva med avseende på den tid och det åtagandet som krävs. En sådan del är medicinska konsultationer för privatpersoner där många av de simplare mötena fortfarande sker i person. Presenterat i denna avhandling är implementationen av ett distribuerat telemedicinsystem som kan användas som ett substitut för de konsultationer mellan doktor och patient som sker i person. Nödvändiga tredjeparts komponenter och deras implementationer in ett system är beskrivna på en allmän användningsnivå. Resultatet är en webbapplikation som stödjer login och betalning via en pålitligt källa, bokning av möten och utförandet av dem med bild och ljud. Den presenterade prototypen är en fortsättning på en telemedicinsk webbapplikationsidé som lagts på is av ett företag som redan erbjuder lösningar för hälsokontroll och blodanalys.

Increasing productivity in software testing : Visualizing and managingarbitrarily structured messages and message queues to increase productivity andusability

Pedersen, Jakob January 2015 (has links)
This thesis investigates how data sources, message queues, and messages can be generalized in such way that it allows for easy configuration and setup in a frontend visualization application. It also includes increasing the productivity of the application testers and the usability of the user interface. An analysis of one of Dewire’s test tools gave insightful information to identify what was needed in the proof-of-concept application and resulted in a list of requirements. The information gained from Dewire also indicated what technologies to use and resulted in a research phase. Different design proposals were presented and one was chosen to be implemented. An agile approach was chosen as method for the implementation phase to emphasize flexibility. It was set to be iterative and in close communication with people at Dewire. The implementation resulted in a proof-of-concept application with a GUI that allows user to configure data sources, message queues and messages. The messages are uploaded in XML format and the GUI allows for modification through HTML forms which mir-rors the XML files. The user is also able to send these messages as JMS mes-sages. Responses to these JMS messages are also shown in the GUI and saved in a database. The results suggest that accomplishing the common task to select a connection tree and send a message takes 45% less time in the proof-of-concept application compared to Dewire’s tool. To accomplish the common task to alter a message and send it takes 79% less time in the proof-of-concept appli-cation compared to Dewire’s tool. The results also suggest that theory of com-puter-human interaction have been applied during the implementation to ac-complisha usable UI. It is assessed that data sources, message queues and mes-sage can be easy configured in a GUI. Further, it is assessed that the productivi-ty has been increased compared to the former tool used.

Blénessy, Tibor January 2011 (has links)
Title: Support for Enterprise Applications in SOFA 2 Author: Tibor Blénessy Department: Department of Distributed and Dependable Systems Supervisor of the master thesis: RNDr. Tomáš Bureš, Ph.D. Abstract: Industry standards defining various aspects of enterprise systems were developed in order to make development of such systems faster and to increase interoperability. For systems created with Java platform, these standards are contained under Java Enterprise Edition. SOFA 2 component system provides a solid base for development of ex- tensive component oriented systems. Goal of this work is to propose and empirically verify the possibility of integration of existing industry standards for enterprise applications in SOFA 2. Proposed solution extends SOFA 2 with components for web user in- terfaces based on Java Servlet API standard and with components for persisting data into relational databases based on Java Peristence API. In addition, it integrates core technologies from the Java Enterprise Edition platform, which should make integration of further standards easier. Keywords: enteprise applications, component system, SOFA 2, Java EE
