1. 1. Performance Assessment of Electrical Motor for Electric Aircraft Propulsion Applications : Evaluation of the Permanent Magnet Motor and its Limitations in Aircraft Propulsion

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Mathias Beckman; Alex Christy Gerald Volden; [2019]
   Keywords : Electric Aircraft; Permanent Magnet Electrical Motor; Losses; Hybrid-Electric Propulsion System; Environment; Global Warming; Aircraft Emission;

   Abstract : This thesis project will evaluate which kind of electrical motor is best suited for aircraft propulsion and which parameters effect the efficiency. An economic analysis was conducted, comparing the fuel price (Jet A1) for a gas turbine and the electricity price for an electric motor of 1MW. READ MORE

3. 2. Carbon footprint and packaging logistics within freight transports: a case study

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Anna-Karin Andersson; [2016]
   Keywords : Freight transport; environmental impact; carbon footprint; load factor; packaging logistics; Earth and Environmental Sciences;

   Abstract : The emissions from the global freight transport sector are continuously growing in a rapid pace. The rise in the transport sector has increased competition and many industries today operate with a just-in-time practise. This has led to a decline in load factor and an increase of empty transports. READ MORE

4. 3. Developing a Semi-Automatised Tool for Grading Brain Tumours with Susceptibility-Weighted MRI

   University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Radiofysik; Umeå universitet/Centrum för medicinsk teknik och fysik (CMTF)

   Author : Maria Duvaldt; [2015]
   Keywords : Glioma grading; astrocytoma; suceptibility-weighted imaging; SWI; local image variance; intratumoural susceptibility signal; ITSS;

   Abstract : Gliomas are a common type of brain tumour and for the treatment of a patient it is important to determine the tumour’s grade of malignancy. This is done today by a biopsy, a histopathological analysis of the tumourous tissue, that is classified by the World Health Organization on a malignancy scale from I to IV. READ MORE

5. 4. Spatial variation of radio frequency magnetic field exposure from clinical pulse sequences in 1.5T MRI

   University essay from Umeå universitet/Institutionen för fysik

   Author : Andreas Forsberg; [2014]
   Keywords : magnetic resonance; exposure; rf; magnetic field strength; crawford cell; magnetisk resonanstomografi; exponering; rf; magnetisk fältstyrka; crawford cell;

   Abstract : Cell biological exposure studies in magnetic resonance imaging (MRI) environment, where a complex mixture of strong magnetic fields are present, have attracted considerable interest in recent years. The outcome of such studies might depend strongly on the conditions, for example exposure parameters and spatial variations of exposure. READ MORE

6. 5. The effect of push-pull management and different fertilization strategies on maize crop yield in central Kenya

   University essay from SLU/Swedish Biodiversity Centre

   Author : Peterson Newton Muchiri Njeru; [2009]
   Keywords : Soil fertility; central Kenya highlands; manure; fodders; fertilizer; smallholder farmers; ‘push-pull’; monoculture; Kenya;

   Abstract : The high population pressure in central Kenya has lead to continuous cultivation with minimal application of nutrient, resulting in nutrient depletion. A study was conducted to determine the effect of 'Push-pull' (intercropping maize with desmodium and napier grass) strategy management and nitrogen application on maize grain yield and soil fertility on smallholder farmer’s fields in three districts of central Kenya highlands.
