Neural networks can be utilized for an ever widening selection of tasks. In this thesis the most common optimization algorithms underlying neural networks are investigated: classical momentum, Nesterov momentum, AdaGrad, AdaDelta, RMSprop, Adam, AdaMax, and Nadam. The underlying mathematics that these algorithms are based on is described. There is a summary of key components of a neural network—ac

The European Union (EU) taxonomy regulation marked a milestone in the sustainable finance agenda. The taxonomy aims to accelerate the mobilisation of public and private finance to support the transition to a net-zero economy. The EU’s taxonomy regulation established a classification system of environmentally sustainable economic activities to provide financiers clarity on what to consider a sustai

Under åren 1965-1974 genomfördes en omfattande bostadsproduktion i Sverige som betecknas miljonprogrammet. Då byggdes en miljon bostäder runtom i landet. Idag finns behov av att renovera dessa bostäder. I samband med det kan energisparåtgärder genomföras för att minska energianvändningen. Detta kan uppfyllas genom att åtgärda otäta väggar och byta ut äldre fönster som medför oönskade värmeförlusteIn order to maintain a good indoor environment, air pollutants such as moisture need to be removed by the ventilation. Among the Swedish Public Health Agency's general advices for ventilation and indoor environment, 3 g/m3 is a guideline value for moisture excess during winter months to not pose a risk to human health. The indoor climate parameters moisture excess, relative humidity and air va

In this paper, the viability of integrating solar power with an already running wind power plant is examined. The study, conducted in cooperation with Eolus, takes place in Anneberg, Sweden, home to three wind turbines with a combined capacity of 10.8 MW. This study examines whether or not it would be profitable to integrate an additional intermittent power source to the wind power plant’s existin

Syftet med detta examensarbete var att undersöka och öka kunskapen om hur olika parametrar påverkar de dynamiska egenskaperna hos balkbroar i stål som används för gångtrafik. Stålbroar används ofta på grund av sin höga hållfasthet och låga vikt. På grund av de lägre statiska lasterna som orsakas av fotgängare är de dynamiska lasterna vanligtvis dimensionerande. För lätta broar med ett lågt förhålThe aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. Due to the lower static loads caused by pedestrians, the dynamic loads are usually decisive. For lightweight bridges with a low

This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. The handheld nanoparticle detector Partec

Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. The aim of this work was to develop a chemical analysis method that enables identification of short-chain fatty acids (SCFA´s) and medium-chain fatty acids (MCFA´s) in a commercial f

Detta är ett undersökande examensprojekt där jag vill översätta kunskap om goda lekmiljöer till fysisk form. I sökandet efter vad som definierar en god lekmiljö har jag formulerat följande frågeställning: ”Hur kan lekmiljöer gestaltas som samspelar med barns fantasi, uppmuntrar tankefrihet, är tillgänglig för alla barn och inte styrande i sin användning?” Jag har genomfört litteraturstudie och erfThis is an exploratory master’s thesis, where I want to translate theoretical and empirical knowledge of sound play environments to physical form. In the search of what defines a sound play environment, I have formulated the following question: ” How can play environments be shaped to enhance the interaction with children’s imagination, encourage freedom of thought, create accessibility to all chi

The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax. Pneumothorax can be life-

Varje år publicerar Socialstyrelsen en kartläggning av den svenska förlossningsvården. Kartläggningen heter “Statistik om graviditeter, förlossningar och nyfödda barn” och beskriver, bland annat, hur ofta den födande drabbas av en allvarliga bristning. Statistiken för hur ofta en allvarlig bristning uppstår i varje svensk region har skiljt sig mellan regionerna sedan 1990. Socialstyrelsen själva uEvery year the National Board of Health and Welfare (NBHW) publishes a survey of Swedish maternity care. The survey is called "Statistics on pregnancies, births and newborn children" and describes, among other things, how often complications in the form of severe tares affect women giving birth in Sweden. The statistics for how often a severe tares occurs in each Swedish region have diff
