  4. 2. Lean, mean sleep machine? : Effects and experiences of a sleep robot intervention for adults with insomnia

    Author : Siri Jakobsson Støre; Annika Norell-Clarke; Maria Tillfors; Børge Sivertsen; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; anxiety; depression; hyperarousal; insomnia; robot; sleep; Psykologi; Psychology;

    Abstract : Many adults suffer from insomnia disorder, struggling to fall asleep, stay asleep, or with early morning awakenings. Hyperarousal is an important predisposing, precipitating and perpetuating factor to insomnia. Anxiety, depression and ADHD are common comorbid disorders, with shared cognitive, behavioral, genetic, and neurological features. READ MORE

  5. 3. Induction Machine Speed Estimation - Observations on Observers

    Author : Bo Peterson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; Elektronik och elektroteknik; Electronics and Electrical technology; estimation; sensorless control; observer; induction machine; Automatiska system; robotteknik; reglerteknik;

    Abstract : This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. READ MORE

    Author : Minghui Tu; Ulf Olofsson; Teresa Moreno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne particles; railway; underground platform; particle concentration; effect factor; Luftburna partiklar; järnväg; underjordisk plattform; partikelkoncentration; effektfaktor; Machine Design; Maskinkonstruktion;

    Abstract : Urban railways have become an essential part of the transportation network of cities due to their convenience and high capacity. To make full use of urban space, many urban railway platforms are built underground. READ MORE

  7. 5. Understanding and Managing Non-functional Requirements for Machine Learning Systems

    Author : Khan Mohammad Habibullah; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Requirements Engineering; Quality Requirements; Machine Learning; NFRs; Non-functional Requirements; Non-functional Requirements; NFRs; Machine Learning; Quality Requirements; Requirements Engineering;

    Abstract : Background: Machine Learning (ML) systems learn using big data and solve a wide range of prediction and decision making problems that would be difficult to solve with traditional systems. However, increasing use of ML in complex and safety-critical systems has raised concerns about quality requirements, which are defined as Non-Functional requirements (NFRs). READ MORE
