JVLMA bibliotēkas Fotogrāfiju un attēlu datubāzes izstrāde: satura aspekts
2017
Bakalaura darbā pētīta Jāzepa Vītola Latvijas Mūzikas akadēmijas bibliotēkas Fotogrāfiju un attēlu datubāzes kvalitāte satura aspektā. Vairākus gadus datubāze nav papildināta vai apsekota, trūkst informācijas par tās izstrādes principiem. Pētījuma mērķis ir izpētīt esošo situāciju, lai uzlabotu datubāzes kvalitāti nākotnē. Darba teorētisko bāzi veido pragmatisma pieeja, “Holistiskais DB novērtēšanas modelis” un digitālo kolekciju izstrādes vadlīniju ieteikumi satura atlasē un metadatu pievienošanā. Izmantojot interviju un kontentanalīzi, noskaidroti satura atlases kritēriji un novērtēti aprakstošie metadati. Rezultāti atklāj, ka atlasē svarīga ir objektu saistība ar Mūzikas akadēmiju, savuk…
Atlas construction and image analysis using statistical cardiac models
2010
International audience; This paper presents a brief overview of current trends in the construction of population and multi-modal heart atlases in our group and their application to atlas-based cardiac image analysis. The technical challenges around the construction of these atlases are organized around two main axes: groupwise image registration of anatomical, motion and fiber images and construction of statistical shape models. Application-wise, this paper focuses on the extraction of atlas-based biomarkers for the detection of local shape or motion abnormalities, addressing several cardiac applications where the extracted information is used to study and grade different pathologies. The p…
Influence of geometric variations on LV activation times: A study on an atlas-based virtual population
2010
We present the fully automated pipeline we have developed to obtain electrophysiological simulations of the heart on a large atlas-based virtual population. This virtual population was generated from a statistical model of left ventricular geometry, represented by a surface model. Correspondence between tetrahedralized volumetric meshes was obtained using Thin Plate Spline warps. Simulations are based on the fast solving of Eikonal equations, and stimulation sites correspond to physiological activation. We report variations of total activation time introduced by geometry, as well as variations in the location of last activation. The obtained results suggest that the total activation time ha…

Electron and photon performance measurements with the ATLAS detector using the 2015-2017 LHC proton-proton collision data
2019
This paper describes the reconstruction of electrons and photons with the ATLAS detector, employed for measurements and searches exploiting the complete LHC Run 2 dataset. An improved energy clustering algorithm is introduced, and its implications for the measurement and identification of prompt electrons and photons are discussed in detail. Corrections and calibrations that affect performance, including energy calibration, identification and isolation efficiencies, and the measurement of the charge of reconstructed electron candidates are determined using up to 81 fb−1 of proton-proton collision data collected at √s=13 TeV between 2015 and 2017.
An Atlas of the Mediterranean Waterfronts: An Instrument for Knowledge and Direction
2016
In order to design the renewal for urban fluidity, the Atlas for Mediterranean Waterfronts is not only an instrument for knowledge, but it is the tool in which we can analyse the contemporary relation between nature and culture. The chapter explains the duality-based atlas that mirrors the condition in city-port urban management and it defines the structure of the Atlas that is founded on urban clusters identities as research field.

Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energ…
2013
A search has been performed for the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transverse momentum. Such a final state may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon and a gravitino while the other decays into a Higgs boson and a gravitino. The search is performed using the full dataset of 7 TeV proton–proton collisions recorded with the ATLAS detector at the LHC in 2011, corresponding to an integrated luminosity of 4.7 fb−1. A total of 7 candidate events are o…
Study of the Contribution of Research into Women Entrepreneurship : A Meta-analysis of Discourses in the Literature using ATLAS.ti
2015
Abstract: In this paper, we have analyzed how existing literature contributes to women entrepreneurship research in terms of theoretical, methodological and practical ways of understanding. Based on relevant contents and discourses, a main line within the trend of development can be seen as women entrepreneurship shifting from a marginalized discipline to a more multi-dimensional research concept. Certain representative issues evoke development or are even being left as “atheoretical” at some point; the “alternative” angle is accordingly significant for an in-depth exploration through the relevant materials. The literature resources are chosen with close attention to the keywords “women ent…
