  1. 1. Code Generation for Accelerating Data Flow : Enhancing Pentaho Data Integration Performance

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alexander Svensson; [2023]
    Nyckelord :;

    Sammanfattning : Pentaho Data Integration, called Kettle, is an ETL tool that functions as a no-code program. The tool, implemented in Java, enables users to create data flow structures via a graphical user interface and store them as XML files, which can be edited or executed. LÄS MER

  3. 2. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Aya Ali; [2022]
    Nyckelord :in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Sammanfattning : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. LÄS MER

  4. 3. Replacing batch-based data extraction withevent streaming with Apache Kafka : A comparative study

    M1-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Richard Axelsson; [2022]
    Nyckelord :etl; kafka connect; resource consumption; sql server;

    Sammanfattning : For growing organisations that have built their data flow around a monolithic database server, anever-increasing number of applications and an ever-increasing demand for data freshness willeventually push the existing system to its limits, prompting either hardware upgrades or anupdated data architecture. Switching from an approach of full extractions of data at regularintervals to an approach where only changes are extracted, resource consumption couldpotentially be decreased, while simultaneously increasing data freshness.

  5. 4. Conforming building models derived in Esri's environment to the Swedish national specification for 3D data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Gudrun Jensdóttir; [2021]
    Nyckelord :Geomatics; GIS; 3D building models; 3D city models; conversion; Esri FileGDB; spatial ETL; FME; MultiPatch; national standard; NS building; transformation; Earth and Environmental Sciences;

    Sammanfattning : Three-dimensional (3D) city models are increasingly utilized among stakeholders of different sectors, particularly those dealing with building information. 3D city models are a three-dimensional digital representation of urban structures, most prominently buildings. LÄS MER

  7. 5. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Nagaraju Gorella; [2021]
    Nyckelord :Perovskites; Solar Cell; SEM; AFM; c-AFM; Photoluminescence; Electroluminescence; Solar simulator.;

    Sammanfattning : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. LÄS MER
