  1. 1. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : Aravin Chakravarthi; Lunds universitet.; Lund University.; [2017-05]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Abstract : Popular Science AbstractHow well bees can see the world?aBees such as bumblebees and honeybees are some of the most important pollinators. They pollinate by using different sensory cues from the flowers, primarily vision and olfaction. READ MORE

  2. 2. Spatial vision in diverse invertebrates

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : John Kirwan; Lunds universitet.; Lund University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vision; visual ecology; invertebrates; spatial resolution; behaviour;

    Abstract : Förmågan att uppfatta ljus och vilken riktning det kommer från är utomordentligt användbart för djur. Därför är det inte förvånande att denna förmåga återfinns hos i stort sett varje större djurgrupp, även bland de som anses enkla, såsom koraller och spolmaskar. READ MORE

  3. 3. Spatial Vision in Birds: Anatomical investigation of spatial resolving power

    Abstract : Popular Abstract in Swedish Fåglar har fascinerat människor i århundraden. Färgen på deras fjädrar, deras flyghöjd och deras förmåga att fånga små byten har skapat den allmänna uppfattningen att fåglar har en fantastisk syn. READ MORE

  4. 4. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    University dissertation from Medical Radiation Physics, Lund University

    Author : Mark Ruschin; Lunds universitet.; Lund University.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE

  5. 5. Spatial distribution and conservation planning of seabed biological diversity

    University dissertation from Medical Radiation Physics, Lund University

    Author : Genoveva Gonzalez-Mirelis; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Abstract : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.
