1. 6. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Karnsinee Viriyayudhakorn; [2023]
   Nyckelord :human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

   Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER

3. 7. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök

   Uppsats för yrkesexamina på avancerad nivå,

   Författare :Frida Aronsson; [2023]
   Nyckelord :contaminated soil; arsenic; zero-value iron; mZVI; pilot test; pilot study; förorenad mark; arsenik; nollvärt järn; mZVI; pilotförsök; pilotstudie;

   Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER

4. 8. Biodiversity Monitoring Using Machine Learning for Animal Detection and Tracking

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Qian Zhou; [2023]
   Nyckelord :Small Target Detection; Target Tracking; YOLOv5; DeepSORT; Attention Mechanism; Loss Function; Feature Extraction and Fusion Network; Detektering Av små sål; sålspårning; YOLOv5; DeepSORT; uppmärksamhetsmekanism; förlustfunktion; fusionsnätverk;

   Sammanfattning : As an important indicator of biodiversity and ecological environment in a region, the number and distribution of animals has been given more and more attention by agencies such as nature reserves, wetland parks, and animal protection supervision departments. To protect biodiversity, we need to be able to detect and track the movement of animals to understand which animals are visiting the space. LÄS MER

5. 9. Sitting on a Goldmine : Exploring Institutional Enablement for Real Estate Market Data Accessibility in Ghana.

   Master-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

   Författare :Naa Kwaamah Otoo-Ankrah; [2023]
   Nyckelord :real estate market data; transaction costs; institutions; information asymmetry; valuation; valuers;

   Sammanfattning : The Ghanaian real estate market, though thriving, grapples with insufficient market data. The lack of data renders the market nontransparent and increases transaction costs. Considering the market performance over the past few years, great potential lies for even more growth if this problem is addressed. LÄS MER

7. 10. Over-the-Air Federated Learning with Compressed Sensing

   Master-uppsats, Linköpings universitet/Kommunikationssystem

   Författare :Adrian Edin; [2023]
   Nyckelord :machine learning; ML; Federated Learning; FL; Over-the-air; Over-the-air computation; OtA; OtA computation; AirComp; Compressed sensing; CS; Iterative Hard thresholding; IHT;

   Sammanfattning : The rapid progress with machine learning (ML) technology has solved previously unsolved problems, but training these ML models requires ever larger datasets and increasing amounts of computational resources. One potential solution is to enable parallelization of the computations and allow local processing of training data in distributed nodes, such as Federated Learning (FL). LÄS MER
