Fotogrammetrijas metode mikrofosīliju 3D modeļu izveidei

2019

Ješkins J. 2019. Fotogrammetrijas metode mikrofosīliju 3D modeļu izveidei. Maģistra darbs. Pētījuma mērķis ir izstrādāt mikrofosīliju 3D rekonstrukcijas metodi, izmantojot fotogrammetrijas principu. Autors piedāvā inovatīvu 3D modeļu izveides metodi, pielietojot attēlu iegūšanu ar optiskās mikroskopijas palīdzību un attēlu fotogrammetrisko apstrādi. Izstrādātā metode ir aprobēta uz dažāda vecuma, izmēra, minerālā un ķīmiskā sastāva mikrofosīlijām, un tiek rekomendēta kā alternatīva esošajām metodēm. Izstrādāta metode var tikt pielietota zinātniskiem nolūkiem pētnieku komandās, kurām nav pieejamas citas, komplicētas un dārgas metodes 3D rekonstrukciju veikšanai. Pētījuma diskusijā autors pie…

An Oral History of Programming Practices: Gender and Age Dynamics and Digital (Dis)Engagement Among Computer Programmers in Finland

2015

Since the 1980s, educational policies in many countries have aimed at improving the computer literacy and programming competencies of the population. Over the same period, the possibilities that people have seen regarding programming and everyday programming practices have emerged as an area of strong interest within historical scholarship. The paper contributes to these discussions by drawing on techniques of oral history to focus on programming hobbies and practices in Finland. Examining data from a massive survey of computer hobbyists (N = 1,453) and their recollections about personal computer use (largely during the 1980s), the paper gathers new information on what leads to people’s pur…

Mathematical and Coding Lessons Based on Creative Origami Activities

2019

AbstractThis paper considers how creativity and creative activities can be encouraged in regular mathematical classes by combining different teaching approaches and academic disciplines. We combined origami and paper folding with fractals and their mathematical properties as well as with coding in Scratch in order to facilitate learning mathematics and computer science. We conducted a case study experiment in a Serbian school with 15 high school students and applied different strategies for learning profound mathematical and coding concepts such as fractals dimension and recursion. The goal of the study was to employ creative activities and examine students’ activities during this process i…

The nature of the syllabic neighbourhood effect in French

2006

International audience; We investigated whether and how sublexical units such as phonological syllables mediate access to the lexicon in French visual word recognition. To do so, two lexical decision task (LDT) experiments examined the nature of the syllabic neighbourhood effect. In Experiments 1a and b, the number of higher frequency syllabic neighbours was manipulated while controlling for the first bigram. The results failed to show a pure syllabic neighbourhood effect. In Experiments 2a and b, syllabic neighbourhood and bigram frequency were factorially manipulated. The interaction showed that the syllabic neighbourhood effect was inhibitory when bigram frequency was high, whereas it wa…

Pulsating B and Be stars in the Small Magellanic Cloud

2008

Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B spectral domain at very low metallicities. As the metallicity of the SMC is lower than Z=0.005, it constitutes a very suitable object to test these predictions. Aims: The main objective is to investigate the existence of B-type pulsators at low metallicities, searching for short-term periodic variability in absorption-line B and Be stars in the SMC. The analysis has been performed in a sample of 313 B and Be stars with fundamental astrophysical parameters accurately determined from high-res…

Asymptotic Lipschitz regularity for tug-of-war games with varying probabilities

2018

We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in $\Omega\subset \mathbb R^n$. The method of the proof is based on a game-theoretic idea to estimate the value of a related game defined in $\Omega\times \Omega$ via couplings.
