Data service platform for sentinel-2 surface reflectance and value-added products: System use and examples
2016
This technical note presents the first Sentinel-2 data service platform for obtaining atmospherically-corrected images and generating the corresponding value-added products for any land surface on Earth (http://s2.boku.eodc.eu/). Using the European Space Agency’s (ESA) Sen2Cor algorithm, the platform processes ESA’s Level-1C top-of-atmosphere reflectance to atmospherically-corrected bottom-of-atmosphere (BoA) reflectance (Level-2A). The processing runs on-demand, with a global coverage, on the Earth Observation Data Centre (EODC), which is a public-private collaborative IT infrastructure in Vienna (Austria) for archiving, processing, and distributing Earth observation (EO) data (http://www.…

Kognitīvās funkcijas normatīvi veseliem bērniem, bērniem ar CSWS sindromu un citiem epilepsijas traucējumiem
2021
Šajā darbā ir apskatītas kognitīvās funkcijas, kurās ietilpst atmiņa, uzmanība, uztvere, vadības funkcijas un valoda, kā arī plašāk apskatīta epilepsija, tās ārstēšana, CSWS sindroms (epilepsija ar nepārtrauktiem smailajiem viļņiem miega laikā), kā arī epilepsijas saistība ar kognitīvajām funkcijām un UDHS (uzmanības deficīta un hiperaktivitātes sindroms). Šī pētījuma mērķis un uzdevums ir izprast un izzināt, vai bērniem ar CSWS sindromu un citiem epilepsijas traucējumiem vizuālās uzmanības, vizuālās un verbālās darba atmiņas, uztveres, vadības un motoro funkciju līmeņi tiek prognozēti zemāki, vai būs izteiktākas uzvedības problēmas, īpaši agresivitāte un hiperaktivitāte, kā arī, vai būs iz…

Facebook lietošanas un personības iezīmju sakarības
2019
Bakalaura darba tēma ir: Personības iezīmju un Facebook lietošanas sakarības. Darbs sastāv no teorētiskās un empīriskās daļas. Darba teorētiskajā daļā tiek raksturots jēdziens personības iezīmes, tiešsaistes sociālais tīkls Facebook, kā arī tiek analizēts personības iezīmju un Facebook lietošanas intensitātes sakarību novērtējums zinātniskajos pētījumos. Empīriskajā daļā tiek aprakstīta pētījuma metode, kā arī tiek analizēti un interpretēti dati, kuri iegūti izmantojot Facebook lietošanas intensitātes aptauju (Facebook Intensity Scale, Ellison, Steinfield, Lampe, 2007; Latvijā aptauju adaptējusi D.Piļka, 2017) un Lielā Piecinieka aptauju (The Big Five Inventory; John & Srivastava, 1999; lat…
Assessment of the Mass and Surface Area of the Scots Pine (Pinus sylvestris L.) Needles
2022
The assessment of the surface area of all leaves from a tree crown is regarded as one of the key parameters in scaling ecophysiological processes, such as growth, carbon budget, and water management. The purpose of this study was to investigate the variation of the mass and surface area of Scots pine needles, obtained from trees growing in the same habitat conditions but at different stock densities, therefore occupying different biosocial positions. The mass of needles and the leaf area index (LAI) were determined for an even-aged 33-year-old Scots pine stand located at a fresh mixed coniferous forest site in southwest Poland (50°32′ N; 17°42′ E). The needles, collected…

Factors associated with first- versus second-generation long-acting antipsychotics prescribed under ordinary clinical practice in Italy
2018
Background For many years, long-acting intramuscular (LAI) antipsychotics have been prescribed predominantly to chronic and severe patients, as a last resort when other treatments failed. Recently, a broader and earlier use of LAIs, particularly second-generation LAIs, has been emphasized. To date, few studies attempted to frame how this change in prescribing took place in real-world practice. Therefore, this study aimed to describe the clinical features of patients prescribed with LAIs, and to explore possible prescribing differences between first- and second-generations LAIs under ordinary clinical practice in Italy. Methods The STAR Network "Depot" Study is an observational, longitudinal…
Monitoring peatland water table depth with optical and radar satellite imagery
2022
Peatland water table depth (WTD) and wetness have widely been monitored with optical and synthetic aperture radar (SAR) remote sensing but there is a lack of studies that have used multi-sensor data, i.e., combination of optical and SAR data. We assessed how well WTD can be monitored with remote sensing data, whether multi-sensor approach boosts explanatory capacity and whether there are differences in regression performance between data and peatland types. Our data consisted of continuous multiannual WTD data from altogether 50 restored and undrained Finnish peatlands, and optical (Landsat 5–8, Sentinel-2) and Sentinel-1 C-band SAR data processed in Google Earth Engine. We calculated rando…
