  2. 1. Flood Prediction in data-scarce basins : Maximising the value of limited hydro-meteorological data

    Author : José Eduardo Reynolds Puga; Sven Halldin; Chong-Yu Xu; Jan Seibert; Thomas J. Grabs; Vazken Andréassian; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Floods; data scarcity; value of information; rainfall-runoff modelling; regionalisation; rainfall-forecasts; event-based calibration; climatological day; discharge day; temporal resolution; modelling time-step.; Databrist; flödestoppsbaserad kalibrering; högflöde; informationsvärde; klimatologiskt dygn; nederbörds-avrinningsmodell; modelltidssteg; regionalisering; regnprognos; tids-upplösning; vattenföringsdygn; översvämning.; Inundaciones; falta de datos; valor de información; modelos lluvia escorrentía; regionalización; pronósticos de lluvia; definición del día; resolución temporal; paso de tiempo.;

    Abstract : Floods pose a threat to society that can cause large socio-economic damages and loss of life in many parts of the world. Flood-forecasting models are required to provide simulations at temporal resolutions higher than a day in basins with concentration times smaller than 24 h. READ MORE

  4. 2. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models

    Author : Nasser Mohammadiha; Arne Leijon; W. Bastiaan Kleijn; Cédric Févotte; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech enhancement; noise reduction; nonnegative matrix factorization; hidden Markov model; probabilistic latent component analysis; online dictionary learning; super-Gaussian distribution; MMSE estimator; temporal dependencies; dynamic NMF;

    Abstract : Reducing interference noise in a noisy speech recording has been a challenging task for many years yet has a variety of applications, for example, in handsfree mobile communications, in speech recognition, and in hearing aids. Traditional single-channel noise reduction schemes, such as Wiener filtering, do not work satisfactorily in the presence of non-stationary background noise. READ MORE

  5. 3. Enforcing Temporal Constraints in Embedded Control Systems

    Author : Kristian Sandström; Mälardalens högskola; []
    Keywords : ;

    Abstract : Computer control systems are embedded in a large and growing group of products, ranging from consumer entertainment products to large airliners. Products such as automotive vehicles, aircraft, and industrial robots are equipped with advanced computer control systems and have high requirements of reliable and safe operation. READ MORE

  6. 4. Permeable islands : A contrastive study of Swedish and English adjunct clause extractions

    Author : Christiane Müller; Svenska; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; acceptability judgments; adjunct islands; coherence; filler-gap dependencies; finiteness; Swedish; syntax;

    Abstract : This dissertation is concerned with extraction from adjunct clauses in Swedish and English. The topic is of interest because adjunct clauses are traditionally considered to be strong islands for extraction across languages (the Adjunct Condition). READ MORE

  7. 5. Towards Behavioral Model Fault Isolation for Object Oriented Control Systems

    Author : Dan Lawesson; Ulf Nilsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unified Modeling Language UML ; Maskinelement Servomekanismer Automation; Computer science; Datavetenskap;

    Abstract : We use a system model expressed in a subset of the Unified Modeling Language to perform fault isolation in large object oriented control systems. Due to the severity of the failures considered and the safety critical nature of the system we cannot perform fault isolation online. READ MORE
