Mārketinga komunikācijas pielietojums auditorijas piesaistei: internetveikalu "AboutYou" un "Membershop" piemēri
2021
Bakalaura darba tēma ir “Mārketinga komunikācijas pielietojums auditorijas piesaistei: internetveikalu “AboutYou” un “Membershop” piemēri". Bakalaura darba ietvaros tiek izpētīts, kāds ir mārketinga komunikācijas pamatuzdevums, kuri mārketinga rīki ir veiksmīgākie, lai piesaistītu auditoriju. Kā arī tiek izanalizēts, cik efektīvs ir internetveikalu “AboutYou” un “Membershop” mārketinga komunikācijas pielietojums auditorijas piesaistei Latvijas tirgū. Darba ietvaros teorētiskajā daļā tiek apskatīta informācija par tēla veidošanu, patērētāju pieņēmumu veidošanos, digitālo mārketingu, mārketinga komunikācijas veidiem, uzņēmuma komunikāciju un sociālajiem tīkliem, jo tie ir kanāli caur kuriem l…
Archeologia dziewiętnastowiecznej pamięci w insurekcyjnym tryptyku Jarosława Iwaszkiewicza ("Noc czerwcowa", "Zarudzie", "Heydenreich")
2013
Three short “insurrection” stories written by Jarosław Iwaszkiewicz in the years 1963–1974 have inspired various interpretations; it seems, however, that there are still many undeciphered codes, references, and allusions. The author’s metatextual comments as well as the implicit poetics of the stories make it possible to consider them as a dialogue with the historical, cultural and aesthetic heritage of the 19th century: as a form of its literary archeology. The article deals with many literary and aesthetic conventions employed in the stories, with the emphasis on the concept of sérénité and on various associations with 19th-century art. Notably, the scope of analysis includes such motifs …

The impact of visual working memory capacity on the filtering efficiency of emotional face distractors.
2018
Emotional faces can serve as distractors for visual working memory (VWM) tasks. An event-related potential called contralateral delay activity (CDA) can measure the filtering efficiency of face distractors. Previous studies have investigated the influence of VWM capacity on filtering efficiency of simple neutral distractors but not of face distractors. We measured the CDA indicative of emotional face filtering during a VWM task related to facial identity. VWM capacity was measured in a separate colour change detection task, and participants were divided to high- and low-capacity groups. The high-capacity group was able to filter out distractors similarly irrespective of its facial emotion. …
Reinforcement learning approach to nonequilibrium quantum thermodynamics
2021
We use a reinforcement learning approach to reduce entropy production in a closed quantum system brought out of equilibrium. Our strategy makes use of an external control Hamiltonian and a policy gradient technique. Our approach bears no dependence on the quantitative tool chosen to characterize the degree of thermodynamic irreversibility induced by the dynamical process being considered, require little knowledge of the dynamics itself and does not need the tracking of the quantum state of the system during the evolution, thus embodying an experimentally non-demanding approach to the control of non-equilibrium quantum thermodynamics. We successfully apply our methods to the case of single- …

Piecewise Affine (PWA) Modeling and Switched Damping Control of Two-Inertia Systems with Backlash
2018
Backlash degrades positioning accuracy and can induce mechanical wear and breakage by collisions. Therefore, a lot of studies have been conducted on backlash compensation. The simplest control method for the impact attenuation is torsional damping addition by feedback of torsional velocity. This paper reveals the advantages and disadvantages of the torsional damping addition. Based on the analyses, a novel switched damping control is proposed to realize the responses with smaller overshoot while attenuating the impact. The mechanical system and the proposed controller are described as piecewise affine systems for analyses. The performance of the proposed method is compared with a linear dam…
Novel multipactor studies in RF satellite payloads: Single-carrier digital modulated signals and ferrite materials
2017
In this work it is reviewed the most novel advances in the multipactor RF breakdown risk assessment devoted to RF satellite microwave passive devices employed in space telecommunication systems. On one side, it is studied the effect of transmitting a single-carrier digital modulated signal in the multipactor RF voltage threshold in a coaxial line. On the other hand, an analysis of the multipactor phenomenon in a parallel-plate waveguide containing a magnetized ferrite slab it is presented.
Fabrication and characterization of low cost Cu 2 O/ZnO:Al solar cells for sustainable photovoltaics with earth abundant materials
2016
Abstract The low cost electrodeposition method was used to grow Cu2O thin films and experimentally determine the optimal absorber layer thickness. Raman scattering studies indicate the presence of solely crystalline Cu2O and SEM images show that the thin films consist of grains with a pyramidal shape. The influence of the thickness of the light absorbing Cu2O layer on the basic characteristic of the heterojunction and their properties have been investigated using reflectivity, current–voltage (J–V), capacitance–voltage (C–V) and the external quantum efficiency (EQE) measurements. The depletion layer, the charge collection length of the minority carrier, and reflectivity are the main factors…
SiC MOSFET vs SiC/Si Cascode short circuit robustness benchmark
2019
Abstract Nowadays, MOSFET SiC semiconductors short circuit capability is a key issue. SiC/Si Cascodes are compound semiconductors that, in some aspects, show a similar MOSFET behaviour. No interlayer dielectric insulation suggests, in theory, Cascode JFETs as more robust devices. The purpose of this paper is to compare the drift and degradation of two commercial devices static parameters by exposing them to different levels of repetitive 1.5 μs short-circuit campaigns at 85% of its breakdown voltage. Short-circuit time has been set experimentally, and longer times result in catastrophic failure of MOSFET devices due to over self-heating. For this purpose, pre- and post-test short circuit ch…
