  1. 1. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Camilla Lane; [2023]
    Keywords : Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

    Abstract : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

  3. 2. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  4. 3. VISUAL DETECTION OF PERSONAL PROTECTIVE EQUIPMENT & SAFETY GEAR ON INDUSTRY WORKERS

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Fredrik Strand; Jonathan Karlsson; [2022]
    Keywords : Machine learning; yolo; yolov4; cnn; ppe; personal protective equipment; object detection; computer vision; deep learning; artificial intelligence; ai; real-time object detection; real-time; safety; construction; workers; industry; face recognition;

    Abstract : Workplace injuries are common in today's society due to a lack of adequately worn safety equipment. A system that only admits appropriately equipped personnel can be created to improve working conditions and worker safety. The goal is thus to develop a system that will improve construction workers' safety. READ MORE

  5. 4. Drone navigation and license plate recognition for vehicle search and classification

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Moa Arvidsson; Sithichot Sawirot; [2022]
    Keywords : ;

    Abstract : This thesis explores the progress of creating a system for detecting license plates and navigating through a garage environment with onboard computing on the nano-drone CrazyFlie 2.1. The system uses the deep learning network MobileNetv2 to classify real-time images from the built-in camera to detect license plates in its immediate environment. READ MORE

  6. 5. Urban infrastructure inundation risk from permanent sea-level rise scenarios in London (UK), Bangkok (Thailand) and Mumbai (India): A comparative analysis

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shawn Pace; [2021]
    Keywords : Geography; GIS; Climate Change; Sea-Level Rise; Urban Infrastructure; DEM; London; Mumbai; Bangkok; Earth and Environmental Sciences;

    Abstract : Due to anthropogenically created climate change, global cities are facing inundation by rising sea levels. This study aimed to fill knowledge gaps in understanding the exposure of urban infrastructure such as roads, railways, buildings and parks to sea-level rise (SLR) scenarios, and how this would affect local populations.
