  1. 1. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Tamina Kabir; [2023-03-08]
    Keywords : ;

    Abstract : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. READ MORE

  3. 2. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Anton Rolseth; [2023]
    Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

  4. 3. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Louise Westin; [2023]
    Keywords : Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

    Abstract : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. READ MORE

  5. 4. Optimization of concrete recipe made with crushed aggregate

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Jonathan Lindekrantz; Pontus Axelsson; [2023]
    Keywords : ;

    Abstract : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. READ MORE

  6. 5. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lukas Jonasson; [2023]
    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE
