Kvadrotora sadarbība ar bezvadu sensoru tīklu
2016
Darbs ir par kiberfizikālajām sistēmām, kas ir strauji augoša datorikas apakšnozare. Pēdējos gados kvadrotoru un bezvadu sensoru tīklu tehnoloģijas ir vienas no nozīmīgākajām kiberfizikālajās sistēmās. To attīstības rezultātā ir radusies interese par šo tehnoloģiju apvienošanu vienā lietojumā. Darbā ir izpētīti dažādi kvadrotora un bezvadu sensoru tīkla sadarības piemēri, kā arī nepieciešamās tehnoloģijas to realizācijai. Darbs ir daļa no Artemis R5-COP projekta, un tas ir izstrādāts LUMII Reālā laika sistēmu laboratorijā. Darbā ir apskatītas LUMII pieejamā kvadrotora, bezvadu sensoru tīkla un MATLAB Simulink iespējas un dažādas lokalizācijas metodes. Darba ietvaros ir izstrādāts demonstrāc…
Rīgas Centrālās bibliotēkas bērnu literatūras nodaļas lasītāju grāmatu izvēles kritēriji
2021
Bakalaura darba mērķis ir uzzināt RCB un tās filiālbibliotēku Bērnu literatūras nodaļu lasītāju grāmatu izvēles kritērijus. Pētījuma teorētisko bāzi veido uzticama teorētiskā informācija, kas palīdz noskaidrot bērnu psiholoģiskās attīstības lomu grāmatu lasīšanas kontekstā un filozofijas virziens fenomenoloģija, kas skaidro indivīdu izpratni par kādu fenomenu. Pētījumā, mērķu sasniegšanai, tiek pielietotas divas pētniecības metodes - anketēšana un intervēšana. Anketēšana tiek izmantota, lai uzzinātu respondentu domas un viedokli konkrētos jautājumos. Intervija tiek veidota ar mērķi uzzināt detalizētāku informāciju par lasītāju grāmatu izvēles kritērijiem no bibliotekāru skatu punkta. Tika v…
Lapkoku praulgrauzis Osmoderma barnabita (Motschulsky, 1845) un citas saproksilofāgās vaboles platlapju dobumos parkos un alejās: daudzveidība un iet…
2015
Parki un alejas mūsdienās ir kļuvuši par nozīmīgu biotopu daudzu apdraudētu saproksilofāgo vaboļu sugu saglabāšanai. Šī bakalaura darba mērķis ir izpētīt dažāda mēroga ekoloģisko faktoru ietekmi uz platlapju dobumus apdzīvojošo saproksilofāgo vaboļu daudzveidību un izplatību divu platlapju kokiem bagātu Latvijas reģionu parkos un alejās. Darba ietvaros veicu atsevišķu koku faunas izpēti ar Bārbera lamatām, kā arī izvērtēju muižu apstādījumu kā potenciālo lapkoku praulgrauža dzīvotņu kvalitāti. Konstatēju, ka lielāka saproksilofāgo vaboļu daudzveidība ir lapkoku praulgrauža apdzīvotos kokos un sausos dobumos ar vertikālu atveri. Secināju, ka Unguros ir iespējama perspektīva lapkoku praulgrau…
EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE
2009
The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…
Atlas of the Baltic languages: from idea to pilot project
2015
Atl as of the B a ltic l a ngu a ge s : from idea to pilot project Dialectologists from Latvian Language Institute of the University of Latvia and the Department of Language History and Dialectology of the Institute of the Lithuanian Language, have developed a proposal for a joint project entitled, The Atlas of the Baltic Languages, which is intended to demonstrate the close kinship of these two Baltic languages. A pilot project, supported by a grant from the University of Latvia and Directorate for the Millenium of Lithuania has been carried out between 2006 and 2008 to determine what the form and eventual content of such an atlas might be. In 2009 a summary of work carried out on the pilo…
Atlas of the Baltic languages: plant names of Slavonic origin
2015
Atlas of the Baltic Languages: Plant Names of Slavonic Origin The article investigates Slavonic-derived plant names in dialects of the two surviving Baltic languages – Latvian and Lithuanian. Historically, these Slavonisms were originally adopted by small-scale regional dialects, which are now disappearing. In 2009, a pilot study for the Atlas of the Baltic Languages was published. It comprised 12 geo-linguistic maps with Latvian, Lithuanian and English commentaries. 2012 saw the publication, in CD format, of the Atlas ’s first volume: Lexis 1: Flora . The material analysed concerns names for: (1) wild plants, e.g., cornflower, nettle, waybread, milfoil, dandelion, plantain; (2) cultivated …
Bunker Cave stalagmites: an archive for central European Holocene climate variability
2012
Holocene climate was characterised by variability on multi-centennial to multi-decadal time scales. In central Europe, these fluctuations were most pronounced during winter. Here we present a record of past winter climate variability for the last 10.8 ka based on four speleothems from Bunker Cave, western Germany. Due to its central European location, the cave site is particularly well suited to record changes in precipitation and temperature in response to changes in the North Atlantic realm. We present high-resolution records of &delta;<sup>18</sup>O, &delta;<sup>13</sup>C values and Mg/Ca ratios. Changes in the Mg/Ca ratio are attributed to past meteoric p…
Parasitism of dolfinfhishes, Coryphaena hippurus and Coryphaena equiselis, in the western Mediterranean (Balearic Islands) and central-eastern Atlant…
1999
A total of 648 dolphinfishes were examined for internal and external parasites in western Mediterranean (Balearic Islands) and central-eastern Atlantic (Canary Islands) waters in order to make a comparative study between the two areas. The specimens studied from the Mediterranean Sea was Coryphaena hippurus, with 62 large individuals captured from May to September and 497 juveniles captured from August to December. The specimens studied from the central-eastern Atlantic were 39 adult C. hippurus and 49 adult Coryphaena equiselis. Parasites were found in 70% of the fish examined, and represented a total of nine endoparasitic taxa: six digeneans (Class Trematoda, Subclass Digenea; Dinurus tor…
Design and development of safety and control systems in ATLAS
2021
El gran colisionador de hadrones, o LHC, es el acelerador de partículas más grande y potente del mundo. Ha sido construido por el CERN, la Organización Europea para la Investigación Nuclear, entre 1998 y 2008 en Ginebra, Suiza. Sucesivas mejoras en el LHC supondrán a partir de mediados del 2027 un incremento de la luminosidad, cuando pasará a llamarse High Luminosity LHC (HL-LHC). Esta tesis se divide en dos partes, por una parte la seguridad y operación de la infraestructura y por otra los sistemas de control y toma de datos. La primera parte de la tesis se dedica a la seguridad y operación de la infraestructura. Después de más de 10 años de funcionamiento, el riesgo de posibles fallos en …
Search for pair production of first or second generation leptoquarks in proton-proton collisions at sqrt(s)=7 TeV using the ATLAS detector at the LHC
2011
This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35 pb−1 of proton-proton collision data recorded by the ATLAS detector at √s=7 TeV. Leptoquarks are searched in events with two oppositely-charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. After event selection, the observed yields are consistent with the predicted backgrounds. Leptoquark production is excluded at the 95% CL for masses MLQ<376 (319) GeV and MLQ<422 (362) GeV for first and second generation scalar leptoquarks, respectively, when assuming the branching fraction of a leptoquark…
