  1. 1. 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

  3. 2. 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

  4. 3. Properties & Stability of Hybrid Pea-Dairy Protein Formulas

    University essay from Lunds universitet/Förpackningslogistik

    Author : Kyriaki-Eirini Moschou; [2023]
    Keywords : properties; stability; hybrid formula; pea-dairy; protein mixtures; development; RTD; Agriculture and Food Sciences;

    Abstract : The aim of this study was to investigate the functional properties and stability of hybrid pea-dairy protein formulas. To achieve this goal, the combination of pea protein isolate (PPI) with dairy proteins such as micellar casein isolate (MCI), sodium caseinate (NaCas), whey protein aggregate (WPA) was evaluated.

  5. 4. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    University essay from KTH/Materialvetenskap

    Author : Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Keywords : ;

    Abstract : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. READ MORE

  6. 5. The effect of material properties on PEM fuel cell catalysts on durable oxidation reduction activity

    University essay from KTH/Kemiteknik

    Author : Xiaoling Jiang; [2023]
    Keywords : PEM fuel cell; catalyst; ORR activity; particle size; degradation; PEM-bränslecell; katalysator; syrgasreduktionsaktivitet; partikelstorlek; åldring;

    Abstract : I detta examensarbete utforskas påverkan av partikelstorleken hos Pt-katalysatorer på kolbärare på syrereduktionen i polymerelektrolytmembran (PEM)-bränsleceller. Den elektrokemiskt aktiva ytarean, aktiviteten för syrereduktion och tillhörande degraderingshastigheter för de undersökta katalysatorerna beräknas och jämförs. READ MORE
