  2. 21. Design Space Exploration of Digital Circuits for Ultra-low Energy Dissipation

    Author : Syed Muhammad Yasser Sherazi; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; ultra low-voltage; ultra low-energy; subthreshold sub-VT ; body biasing; pipelining; unfolding; half-band digital filter.;

    Abstract : The ever expanding market of ultra portable electronic products is compelling the designer to invest major efforts in the development of small and low energy electronic devices. The driving force and benefactors of such devices are (but not limited to) e-health system, sensor network applications, security systems, environmental applications, and home automation systems.

  4. 22. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain

    Author : Faming Wang; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal manikin; clothing ensemble; evaporative resistance; localised evaporative resistance; thermophysiological response; heat stress; heat strain; the Predicted Heat Strain PHS model;

    Abstract : Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. READ MORE

  5. 23. Studies of artificial mass bias in isotopic measurements by inductively coupled plasma mass spectrometry

    Author : Henrik Andrén; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Mass spectrometry, and especially inductively coupled plasma mass spectrometry (ICP-MS), suffers heavily from mass bias, or instrumental mass discrimination. The nett result of this effect is the preferential transmission, most often of heavier ions through the mass spectrometer. READ MORE

  6. 24. Turbulent Structure of the Marine Atmospheric Boundary Layer and Its Implications for the Inertial Dissipation Method

    Author : Anna Sjöblom; Jørgen Højstrup; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Abstract : In order to improve climate- and weather forecasting models, a better knowledge of the physical processes taking place in the lowest part of the atmosphere over the oceans is essential. In these models it is often assumed that the atmospheric boundary layer over sea behaves in the same way as that over land. READ MORE

  7. 25. Cryogenic Ultra-Low Noise InP High Electron Mobility Transistors

    Author : Joel Schleeh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MMIC; LNA; cryogenic; low noise; DC power dissipation; ALD; GaAs MHEMT; gain fluctuations; InP HEMT;

    Abstract : Indium phosphide high electron mobility transistors (InP HEMTs), are today the best transistors for cryogenic low noise amplifiers at microwave frequencies. Record noise temperatures below 2 K using InP HEMT equipped cryogenic low noise amplifiers (LNAs) were demonstrated already a decade ago. READ MORE
