1. 11. Lekfull matematikundervisning i förskoleklass-lärarnas perspektiv

   M1-uppsats, Luleå tekniska universitet/Pedagogik, språk och Ämnesdidaktik

   Författare :Nina Säisä; [2020]
   Nyckelord :Matematik; lek; lekfull undervisning; material;

   Sammanfattning : Syftet med den här studien är att undersöka hur eleverna får lära sig matematik på ett lekfullt sätt i förskoleklassen utifrån lärarnas perspektiv. Syftet konkretiseras genom frågeställningarna: Vilka metoder använder lärarna i sin undervisning? Vilket material används i undervisningen? Slutligen hur lärarna upplever de lekfulla undervisningssituationerna? Studien genomfördes genom semistrukturerade intervjuer med lärare som tidigare har arbetat eller arbetar i en förskoleklass inom samma kommun. LÄS MER

3. 12. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Evangelos Oikonomopoulos; [2020]
   Nyckelord :Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

   Sammanfattning : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. LÄS MER

4. 13. Ashish Vivekar (2020) Evaluation of methodology for estimating crop yield from multispectral UAV images : a case study at Lönnstorp, Sweden

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Ashish Vivekar; [2020]
   Nyckelord :Physical Geography and Ecosystem analysis; Multispectral Sensor; Radiometric Correction; Reflection calibration; Phenology; GEM; Earth and Environmental Sciences;

   Sammanfattning : Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. LÄS MER

5. 14. Reconstruction of Genome-Scale Metabolic Models with Concomitant Constraint-Based Modelling for Flux Prediction – a Case Study of Syngas Consuming Hydrogenophaga pseudoflava

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi

   Författare :Cristopher Ollagnier Widén; [2020]
   Nyckelord :Applied Microbiology; flux-balance analysis FBA ; genome-scale metabolic model GEM ; Hydrogenophaga pseudoflava DSM 1084; KEGG; metabolic engineering; metabolic modelling; metabolic network reconstruction; RAVEN; syngas; systems biology; Technology and Engineering;

   Sammanfattning : Metabolic modelling coupled with flux-balance analysis (FBA) has become a popular tool in systems biology for quantitative predictions of metabolic processes in silico, and as an aid in metabolic engineering. Drawing upon gene-protein-reaction associations deducible from information on the genome-level, so-called genome-scale metabolic models (GEMs) are unequalled in their scope as they attempt to encapsulate the entire reactome of a species or cell type.

7. 15. Unit commitment model development for hydropower on the Day-Ahead spot market.

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Romain Radulesco; [2020]
   Nyckelord :Unit Commitment Problem; Hydropower; Electricity Exchange; Spot Market; Mixed Integer Linear Programming; Optimization; GAMS; Water Value; Water Transfer; Multi-reservoir;

   Sammanfattning : In the aftermath of the liberalization of European Energy Markets in the 2000s, Power Exchange platforms have constantly evolved towards more integrated and competitive designs, where quality forecasts and effective optimization strategies play decisive roles. This study presents the development of a hydropower scheduling optimization algorithm for the Day-Ahead spot market using Mixed Integer Linear Programming (MILP). LÄS MER
