  1. 6. 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. 7. Multivariate Aspects of Phylogenetic Comparative Methods

    Författare :Krzysztof Bartoszek; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER

  4. 8. A regression approach for assessment of building energy performance

    Författare :Jimmy Vesterberg; Thomas Olofsson; Mohsen Soleimani-Mohseni; Björn Reidar Sörensen; Sofia Lidelöw; Umeå universitet; []
    Nyckelord :building energy simulation; measurements; regression; calibration parameters;

    Sammanfattning : Reliable evaluation methods is needed to ensure that investments in energy conservation measures (ECMs) and the construction of new energy efficient buildings lives up to the promised and expected performance.This thesis presents and evaluates a regression method for estimation of influential building parameters: transmission losses above ground (including air leakage), ground heat loss, and overall heat loss coefficient.

  5. 9. Semantic regression in finance

    Författare :Henrik Talborn; Handelshögskolan i Stockholm; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : "Conditionally decomposed sLDA for characteristics decomposition and company classification" presents an extended topic model which address the problem to uncover subtle patterns related to company characteristics in text. “A method for semantic regression” proposes a method where interpretable clusters of sentences constitute the approximation of the semantic structure and hence allow for qualitative in-depth analysis of the relation between text and company characteristics.

  7. 10. Progression and Regression. Aspects of Advanced Swedish Students' Competence in English Grammar

    Författare :Monica Karlsson; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; Engelska språk och litteratur ; English language and literature; error gravity; proper noun; identification frame; genericness; the zero article; ‘idiomatic’ prepositional use; ‘systematic’ prepositional use; ‘basic’ prepositional use; non-contiguous subject-verb construction; contiguous subject-verb construction; subject-verb concord; fossilisation; restructuring of information; automatisation; interlanguage; cognitive second language acquisition theory; U-curve development; regression; progression; developmental pattern; relative frequency; error score; potential error; developmental continuum; advanced learner; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik; Applied linguistics; foreign languages teaching; sociolinguistics; Tillämpad lingvistik; undervisning i främmande språk; sociolingvistik;

    Sammanfattning : This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. LÄS MER
