FPV dronu konfigurācija
2021
Bakalaura darbs “FPV Dronu Konfigurācija” izstrādāts ar mērķi izpētīt un dokumentēt FPV dro-na konfigurācijas procesu. Autors aplūkoja drona konfigurēšanās valdošos nosacījumus un šīs procedūras posmus, bakalaura darbā norādot autora ieskatā labāko drona konfigurēšanās shēmu. Autors, pievēršot uzmanību tādām programmām kā “OpenTX”, “OpenTX Configurator”, “Express LRS”, “ExpressLRS Configurator”, “Betaflight”, “Betaflight Configurator”, konstatē kā minētās programmas ir drona un radio raidītāja jeb kontrollera sastāvdaļas. Tāpat autors aplū-koja tādas drona sastāvdaļas kā ātruma kontrolleris, motors, lidojuma kontrolleris, rāmis, video raidītājs, propelleri un kamera. Tādējādi bakalaura darb…
Deep and Meaningful E-Learning with Social Virtual Reality Environments in Higher Education: A Systematic Literature Review
2021
Deep and meaningful learning (DML) in distant education should be an essential outcome of quality education. In this literature review, we focus on e-learning effectiveness along with the factors and conditions leading to DML when using social virtual reality environments (SVREs) in distance mode higher education (HE). Hence, a systematic literature review was conducted summarizing the findings from thirty-three empirical studies in HE between 2004 (appearance of VR) and 2019 (before coronavirus appearance). We searched for the cognitive, social, and affective aspects of DML in a research framework and studied their weight in SVREs. The findings suggest that the use of SVREs can provide aut…
The Joint SLR (Optical Range) and Radar-VLBI Satellite Observations using VIRAC Radio Telescope RT32, RT16 and SLR Station Riga
2020
Abstract Joint VLBI and SLR satellite tracking is a novel tracking approach to explore potential applications and to work out common procedures to coordinate observations between astronomical observatories in Latvia. Global Navigation Satellite System (GNSS) satellites equipped with laser retroreflectors have been chosen as test targets because they are accessible by both measuring techniques – satellite laser ranging (SLR) and Very Long Base Interferometry (VLBI). The first Joint SLR and VLBI observations of selected GNSS satellites using three of Latvian large-scale astronomical utilities – VIRAC radio telescopes RT32 and RT16 (Ventspils International Radio Astronomy Centre of Ventspils U…
DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY
2015
The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…
