  2. 2. Variational Inference of Dynamic Factor Models

    Author : Erik Spånberg; Pär Stockhammar; Gebrenegus Ghilagaber; Sune Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic factor models; variational inference; missing data; nowcasting; expectation maximization; statistik; Statistics;

    Abstract : When we make difficult and crucial decisions, forecasts are powerful and important tools. For that purpose, statistical models can be our most effective aid. Ideally, these models can incorporate large sets of multifaceted data. READ MORE

  3. 3. Epidemiological and statistical basis for detection and prediction of influenza epidemics

    Author : Armin Spreco; Toomas Timpka; Olle Eriksson; Örjan Dahlström; Jonas Ludvigsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : A large number of emerging infectious diseases (including influenza epidemics) has been identified during the last century. The emergence and re-emergence of infectious diseases have a negative impact on global health. Influenza epidemics alone cause between 3 and 5 million cases of severe illness annually, and between 250,000 and 500,000 deaths. READ MORE

  4. 4. Advanced Analog MMICs for mm-wave Communication and Remote Sensing in 0.15µm mHEMT Technology

    Author : Marcus Gavell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GaAs; Point-To-Point; E-band; Modulators; HEMT; Receiver; microwave; Mixers; Geostationary; mm-wave;

    Abstract : Multi-Gigabit per second wireless communication and atmospheric remote sensing for weather forecasts are new applications in the mm-wave frequency spectra. The High Electron Mobility Transistor is an excellent technology for high frequency mm-wave applications. Its low noise and linear performance makes a 0. READ MORE

  5. 5. A Challenge-driven Framework for Innovations in Railways

    Author : Veronica Jägare; Ramin Karim; Per-Olof Larsson-Kråik; Ulla Juntti; Mirka Kans; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway; Innovation; Implementation; Digitalisation; Maintenance; Data governance; Cross-organisation; eMaintenance; Industrial AI; Maintenance contracts; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The railway is often perceived as an industry where new technology is not utilised to its full potential. However, the future of the railway and its ability to respond to future transportation demands lies in its ability to adopt, adapt, implement, and integrate emerging technology. These technologies are expected to lead to, e.g. READ MORE
