  2. 16. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers

    Author : Mohammad Anowar Masud; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LNA; MMIC; FinFET; CMOS; HEMT; GaAs; WLP; VGA; BCB;

    Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE

  4. 17. Automated CtP Calibration for Offset Printing : Dot gain compensation, register variation and trapping evaluation

    Author : Shahram Hauck; Sasan Gooran; Björn Kruse; Peter Nussbaum; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Although offset printing has been and still is the most common printing technology for color print productions, its print productions are subject to variations due to environmental and process parameters. Therefore, it is very important to frequently control the print production quality criteria in order to make the process predictable, reproducible and stable. READ MORE

  5. 18. Millimeter-Wave High-Gain Antenna for 5G Backhauling with Auto-beam-tracking Function

    Author : Enlin Wang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gap waveguide; auto-beam-tracking; 5G backhaul; Ultra-high-gain antenna; me- chanical movement;

    Abstract : As microwave links are increasingly deployed within the millimeter-wave frequency range, E-band (70/80 GHz) links have been installed on a global scale. One major technological challenge in this high-frequency spectrum is the significant increase in path loss between receivers and transmitters. READ MORE

  6. 19. Cognitive training in young and old adults : Transfer, long-term effects, and predictors of gain

    Author : Petra Sandberg; Anna Stigsdotter Neeyl; Michael Rönnlund; Boo Johansson; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive training; aging; old adults; executive function; life-span; individual differences; episodic memory; inhibition; shifting; updating; cognitive control; strategy training; mnemonics; predictors; Psychology; psykologi;

    Abstract : Aging, also in the absence of pathological conditions, is associated with cognitivedecline, especially in so called fluid abilities, such as episodic memory andexecutive functions. Due to an ongoing demographic shift, a larger part of thepopulation will reach higher ages, and more people will be affected by age-relatedcognitive decline. READ MORE

  7. 20. Channel Gain Prediction for Cooperative Multi-Agent Systems

    Author : Markus Fröhle; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; channel prediction; multi-agent systems; spatial correlation; wireless ad-hoc networks; parameter learning; distributed algorithms;

    Abstract : In a cooperative multi-agent system (MAS), agents communicate with each other using the wireless medium. As agents move in the environment in order to fulfill the MAS' higher level task, their location changes and so does the wireless communication channel they experience. READ MORE
