  1. 11. Building Orientation and Non-Image Forming Effects of Light. Connecting Simulation and reality in the case of Iggesund School.

    University essay from KTH/Ljusdesign

    Author : Gregor Ruta; [2022]
    Keywords : Alfa-Opic Metrics; Spectral Diet; OWL – Occupant Well-being through Lighting; Chronobiology; Daylight; Circadian Rhythmes; Melatonin; Vision;

    Abstract : In recent years there has been an increase in the number of apartments in Sweden. The officials are estimating that approximately 1000 primary schools need to be built to meet the 20% increase in students. Facing the rising demand; my thesis makes a contribution to sustainable school design via optimisation of the building orientation. READ MORE

  2. 12. Turing's model for pattern formation

    University essay from KTH/Fysik

    Author : Oskar Forsström; Oskar Falgén Nikula; [2022]
    Keywords : Reaction-diffusion; Turing pattern; morphogen; Grier-Meinhardt; Schnakenberg; numerical analysis; minimum energy control;

    Abstract : In an attempt to describe how patterns emerge in biological systems, Alan Turing proposed a mathematical model encapsulating the properties of such processes. It details a partial differential equation governing the dynamics of two or more substances, called morphogens, reacting and diffusing in a specific manner, in turn generating what has now come to be denoted as Turing patterns.

  3. 13. Assessing the impact of post-fire restoration interventions using spectral vegetation indices: A case study in El Bruc, Spain

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Bernat Dorado Guerrero; [2022]
    Keywords : geography; GIS; restoration intervention; drylands; monitoring; BACI; spectral vegetation indices; Earth and Environmental Sciences;

    Abstract : Ecological restoration has become an increasingly used practice to revert degraded land and mitigate the effects of extreme events in vulnerable biomes such as drylands. Methods to improve the assessment of these restoration interventions are essential to ensure their success, optimize resources and identify improvement aspects for future interventions. READ MORE

  4. 14. Dye sensitzation effects on lanthanide upconversion nanoparticles

    University essay from KTH/Fysik

    Author : Dag Albin Bäck; Andreas Jörgensen; [2022]
    Keywords : Dye sensitization; lanthanide upconversion nanoparticles; upconversion nanoparticles; UCNP; IR806;

    Abstract : In this report we studied the properties of the dye IR806 and possible mechanisms of the dye sensitization effect on ytterbium-erbium co-doped upconversion nanoparticles. We found that the dye IR806 has two primary emission peaks in the NIR spectral range at around 850 nm and at around 950 nm. READ MORE

  5. 15. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    University essay from SLU/Dept. of Ecology

    Author : Bina Johansson; [2022]
    Keywords : volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Abstract : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. READ MORE
