  1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  2. 2. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  3. 3. Phase Change Material : Potential for increased fire resistance in concrete

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : William Toivanen; [2023]
    Keywords : Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

    Abstract : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. READ MORE

  4. 4. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Tapas Das; [2023]
    Keywords : Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Abstract : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. READ MORE

  5. 5. Root-cause analysis with data-driven methods and machine learning in lithium-ion battery tests : Master's thesis about detecting deviations with PCA
