    Abstract : Popular Abstract in Swedish Växters fenologi påverkar ekosystemens funktion och tjänster, och återkopplar till klimatet genom att påverka utbytet av kol, vatten och energi mellan atmosfär och ekosystem. Under de senaste decennierna har växternas fenologi studerats i allt större omfattning, men fortfarande är osäkerheten stor och enighet saknas om klimatets inverkan på fenologi och förändringar över tiden.

    Abstract : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

  3. 3. Fourier transform and Vernier spectroscopy using optical frequency combs

    University dissertation from Umeå : Umeå University

    Author : Amir Khodabakhsh; Umeå universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical frequency comb spectroscopy; molecular absorption; resonant cavity; Fourier transform spectroscopy; Vernier spectroscopy; fysik; Physics;

    Abstract : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

  4. 4. Sampling visual space: topography, colour vision and visually guided predator avoidance in fiddler crabs (Uca vomeris)

    University dissertation from Research School of Biological Sciences, The Australian National University

    Author : Jochen Smolka; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Many animals use vision to guide their behaviour and to collect relevant information about their environment. The diversity of visual environments and of visually guided tasks has led to a large variety of specialisations of eyes and visual systems. READ MORE

    Abstract : Popular Abstract in Swedish Eld och kontroll av denna samt dess användning anses vara en av människans äldsta och mest betydelsefulla teknologier som hjälpt till att bana väg för vår väsentliga framgång från stenåldern ända fram till vårt nutida samhälle. Det är därför inte konstigt att vi idag lever i en värld där mer än 90 % av vårt dagliga energibehov täcks genom förbränning av fossila och förnyelsebara bränslen. READ MORE
