  1. 1. Anaerobic digestion in continuous stirred tank reactors and plug flow reactors: : Comparison study concerning process performance

    Master-uppsats, KTH/Kemiteknik

    Författare :Zeko Kocak; [2022]
    Nyckelord :Anaerobic digestion; municipal waste; continuous stirred tank reactor; plug flow reactor; biogas; Anaerob rötning; kommunalt avfall; kontinuerlig omrörd tankreaktor; pluggflödesreaktor; biogas;

    Sammanfattning : Användningen av kommunalt avfall för att producera förnybar energi, huvudsaklig biogas, uppfyller 8 av Sveriges 16 miljökvalitetsmål. Två typer av rötningsprocesser som används är kontinuerligt omrörda tankreaktorer (CSTR) och pluggflödesreaktorer (PFR). LÄS MER

  3. 2. Multi-Task Convolutional Learning for Flame Characterization

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Obaid Ur Rehman; [2020]
    Nyckelord :Multi task learning; multi task convolutional learning; transfer learning; VGG16; CNN; convolutional neural networks; MTL; MTL CNN;

    Sammanfattning : This thesis explores multi-task learning for combustion flame characterization i.e to learn different characteristics of the combustion flame. We propose a multi-task convolutional neural network for two tasks i.e. LÄS MER

  4. 3. Optimal steady-state design of bioreactors in series with Monod growth kinetics

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Molin Hanna; [2018]
    Nyckelord :bioreactor; CSTR; PFR; optimization; modelling; Monod kinetics; decay rate; bioreaktorer; CSTR; PFR; optimering; modellering; Monod-kinetik; avdödningshastighet;

    Sammanfattning : Bioreactors are used to carry out bioprocesses and are commonly used in e.g. biogas production and wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). LÄS MER

  5. 4. µHDS system for desulfurization of logistic fuels for fuel cell applications

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Johan Karstensson; Nicklas Jönsson; [2016]
    Nyckelord :Jet fuel; DBT; thiophene; HDS; catalysis; kemiteknik; chemical engineering; Jet A1; Technology and Engineering;

    Sammanfattning : Logistic fuels such as diesel and petrol, in which Jet A1 is included, are sulfur-containing fuels used for transports. The main problem with logistic fuels, when used in fuel cell (FC) applications, is their relatively high concentration of sulfur compounds. LÄS MER

  7. 5. A comparative analysis of Cisco Performance Routing (PfR) and other performance enhancing techniques - Cisco QoS and Path Control

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Muhammad Younas; [2011]
    Nyckelord :Network performance enhancing techniques; comparative analysis; Cisco PfR; QoS; Path Control;

    Sammanfattning : Eleven years ago Cisco introduced three types of applications on the same converged network and named it AVVID (Architecture for Voice, Video and Integrated Data). In spite of the initial interest and hype surrounding AVVID, the feature was and still is unable to confront problems such as: data priority, load balancing and network congestion. LÄS MER
