  1. 1. CMOS Data Converters for Closed-Loop mmWave Transmitters

    Author : Victor Åberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; SAR ADC; IQ-modulator; Data converter; mmWave; RF-DAC;

    Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.

  2. 2. Source-channel coding for closed-loop control

    Author : Lei Bao; Mikael Skoglund; Karl Henrik Johansson; Fredrik Gunnarssson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal control; joint source--channel coding; source-channel coding; joint coding and control; certainty equivalence; linear quadratic control; stochastic control; wireless sensor network; Telecommunication; Telekommunikation;

    Abstract : Networked embedded control systems are present almost everywhere. A recent trend is to introduce wireless sensor networks in these systems, to take advantage of the added mobility and flexibility offered by wireless solutions. In such networks, the sensor observations are typically quantized and transmitted over noisy links. READ MORE

  3. 3. Negotiated knowledge positions : communication in trauma teams

    Author : Maria Härgestam; Maritha Jacobsson; Christine Brulin; Magnus Hultin; Eric Carlström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; communication; discourse psychology; ideological dilemma; interpretative repertoires; leadership; non-verbal communication; position; power; team work; time; trauma team; trauma team training; silence;

    Abstract : Background Within trauma teams, effective communication is necessary to ensure safe and secure care of the patient. Deficiencies in communication are one of the most important factors leading to patient harm. Time is an essential factor for rapid and efficient disposal of trauma teams to increase patients’ survival and prevent morbidity. READ MORE

  4. 4. Circuit Design Techniques for Implantable Closed-Loop Neural Interfaces

    Author : Nikola Ivanisevic; Ana Rusu; Saul Rodriguez; Angel Rodriguez Vazquez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural interface; ECoG; high-resolution; ADC; recording; delta-sigma modulator; system identification; impedance measurements; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Implantable neural interfaces are microelectronic systems, which have the potential to enable a wide range of applications, such as diagnosis and treatment of neurological disorders. These applications depend on neural interfaces to accurately record electrical activity from the surface of the brain, referred to as electrocorticography (ECoG), and provide controlled electrical stimulation as feedback.

  5. 5. Creating clarity and managing complexity through co-operation and communication : The case of Swedish icebreaker operations

    Author : Magnus Boström; Jesper Andreasson; Cecilia Österman; Carl Hult; Johan Karltun; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maritime safety; organization; human factors; closed-loop communication; Standard Marine Communication Phrases; misunderstanding; other-initiated repair; Sjöfartsvetenskap; Maritime Science;

    Abstract : Sea transportation is vital for the global economy, and the amount of seaborne trade is expected to increase in the future. In some areas, icebreakers are necessary for maintaining open shipping lanes all-year round and ensuring safe navigation. READ MORE
