  1. 1. Improved building energy simulations and verifications by regression

    Författare :Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Sammanfattning : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

  3. 2. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    Författare :Karl Lundengård; Sergei Silvestrov; Dietrich von Rosen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.

  4. 3. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation

    Författare :Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. LÄS MER

  5. 4. Sound perception and design in multimodal environments

    Författare :PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. LÄS MER

  7. 5. Essays on Empirical applications of Real Estate Economics and Finance

    Författare :Mo Zheng; Han-Suck Song; Mats Wilhelmsson; Fredrik Armerin; Shahiduzzaman Quoreshi; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Real Estate Economics and Finance; Hedonic regression; Spatial econometrics; Residential market; Housing index; GARCH; Volatility forecasting; COVID-19; Value-at-Risk; Extreme Value Theory; Fastighetsekonomi och finans; Hedonisk regression; Spatial ekonometri; Bostadsmarknad; Bostadsindex; GARCH; Volatilitetsprognoser; COVID-19; Value-at-Risk; Extreme Value Theory; Fastigheter och byggande; Real Estate and Construction Management;

    Sammanfattning : This doctoral thesis is a collection of four essays that utilize cross-sectional and time-series econometric methods in real estate economics and finance. The first two essays apply econometric modeling to the residential market focusing on hedonic regression analysis, while the other two essays apply financial econometric modeling on an index of listed real estate stocks, and house price index indices.
