Predicting valuable forest habitats using an indicator species for biodiversity
2020
Intensive management of boreal forests impairs forest biodiversity and species of old-growth forest. Effective measures to support biodiversity require detection of locations valuable for conservation. We applied species distribution models (SDMs) to a species of mature forest, the northern goshawk (Accipiter gentilis, goshawk), that is often associated with hotspots of forest biodiversity. We located optimal sites for the goshawk on a landscape scale, assessed their state under intensified logging operations and identified characteristics of goshawks' nesting sites in boreal forests. Optimal sites for the goshawk covered only 3.4% of the boreal landscape and were mostly located outside pro…
Ķīnas politiskā un ekonomiskā interese Baltijas jūras reģionā
2020
Bakalaura darba tēma ir “Ķīnas politiskā un ekonomiskā interese Baltijas jūras reģionā”. Darba mērķis ir izpētīt Ķīnas politiskās un ekonomiskās intereses Baltijas jūras reģionā, kā arī aplūkot kādi iekšēji un ārēji faktori varētu būt vadījuši līdzšinējo Ķīnas pieeju šajā reģionā. Par darba teorētisko bāzi tiks izmantota sinerģija starp defensīvā neoreālisma un konstruktīvisma teorijām, autoram tā cenšoties parādīt gan materiālos, gan ideoloģiskos apsvērumus Ķīnas rīcībai un interesēm.
FREE SPACE OPTICS LINKS AFFECTED BY OPTICAL TURBULENCE: CHANNEL MODELING, MEASUREMENTS AND CODING TECHNIQUES FOR ERROR MITIGATION
2014
FSO is an optical wireless line-of-sight communication system able to offer good broadband performance, electromagnetic interference immunity, high security, license-free operation, low power consumption, ease of relocation, and straightforward installation. It represents a modern technology, significantly functional when it is impossible, expensive or complex to use physical connections or radio links. Unfortunately, since the transmission medium in a terrestrial FSO link is the air, these communications are strongly dependent on various atmospheric phenomena (e.g., rain, snow, optical turbulence and, especially, fog) that can cause losses and fading. Therefore, in worst-case conditions, i…
