Optimality of Increasing Stability for an Inverse Boundary Value Problem
2021
In this work we study the optimality of increasing stability of the inverse boundary value problem (IBVP) for the Schrödinger equation. The rigorous justification of increasing stability for the IBVP for the Schrödinger equation were established by Isakov [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and by Isakov et al. [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141]. In [Discrete Contin. Dyn. Syst. Ser. S, 4 (2011), pp. 631--640] and [Inverse Problems and Applications, Contemp. Math. 615, American Math Society, Providence, RI, 2014, pp. 131--141], the authors showed that the stability of this IBVP increases …
Can Individual Movement Characteristics Across Different Throwing Disciplines Be Identified in High-Performance Decathletes?
2020
Although the individuality of whole-body movements has been suspected for years, the scientific proof and systematic investigation that individuals possess unique movement patterns did not manifest until the introduction of the criteria of uniqueness and persistence from the field of forensic science. Applying the criteria of uniqueness and persistence to the individuality of motor learning processes requires complex strategies due to the problem of persistence in the learning processes. One approach is to examine the learning process of different movements. For this purpose, it is necessary to differentiate between two components of movement patterns: the individual-specific component and …
Unique continuation results for certain generalized ray transforms of symmetric tensor fields
2022
Let $I_{m}$ denote the Euclidean ray transform acting on compactly supported symmetric $m$-tensor field distributions $f$, and $I_{m}^{*}$ be its formal $L^2$ adjoint. We study a unique continuation result for the normal operator $N_{m}=I_{m}^{*}I_{m}$. More precisely, we show that if $N_{m}$ vanishes to infinite order at a point $x_0$ and if the Saint-Venant operator $W$ acting on $f$ vanishes on an open set containing $x_0$, then $f$ is a potential tensor field. This generalizes two recent works of Ilmavirta and M\"onkk\"onen who proved such unique continuation results for the ray transform of functions and vector fields/1-forms. One of the main contributions of this work is identifying t…

4.klašu skolēnu matemātisko prasmju pilnveide integrētā mācību procesā
2019
Baklaura darba tēma “4.klašu skolēnu matemātisko prsmju pilnveide integrētā mācību procesā”. Darba autore Sigita Kalmača, darba vadītāja profesore Dr.paed. Anita Petere. Bakalaura darbā ir 6 lapaspuses, 32 avoti, 5 attēli, 10 tabulas. Baklaura darba mērķis ir teorētiski izzināt un praktiski pārbaudīt matemātisko prasmju pilnveides iespējas integrētā mācību procesā. Lai sasniegtu bakalaura darba mērķi, darba autore veica pedagoģiskās un psiholoģiskās literatūras analīzi un praktiskā pētījumā, veidojot skolēniem integrētu mācību stundu modeļus, pētīja 4.klases skolēnu matemātisko prasmju pilnveides iespējas. Praktiskā pētījuma rezultātā bakalaura darba autore secina, ka, ja sākumskolas skolēn…
Granice wiedzy o literaturze. Słowo o kilku nowych ujęciach interdyscyplinarności (z dodatkiem jednego przykładu)
2015
The paper consists of the review of a number of academic approaches to interdisciplinary research as represented by the Polish theorists of literature (Andrzej Hejmej, Michał P. Markowski, Ryszard Nycz). On the example taken from Tadeusz Nowak’s novel A jak królem, a jak katem będziesz, the author attempts to identify the nature of the close relations between anthropological and literary discourses, where the border line between them lies, and, consequently, what benefits for literary studies stem from anthropological readings.

Varas/valdnieka tēls mūsdienu krievu folkloras tekstos: konstruēšanas mehānismi un recepcijas problēma.
2021
Bakalaura darbs ir veltīts varas un valdnieka tēla izpētei mūsdienu krievu folkloras tekstos. Tiek pētīti varas un valdnieka konstruēšanas mehānismi un recepcijas problemātika, analizējot valdnieka un varas tēlus, kas ir rādīti oficiālajos mediju platformās, gan folkloru, kas ir rādīts kā atbildes reakcija. Tiek vērsta uzmanība pie izmantotiem politiskā mīta veidosānas mehanismiem un rituāliem, to atspoguļošanu masu medijos un ofisiālajos valsts avotos. Kā arī tiek vērsta uzmanība pie mūsdienu interneta folkloras kā atbildes materiāls uz oficiālājiem medijiem. Pētījums var interesēt folkloristus un filologus, kas nodarbojas ar valdības/ valdnieka tēlu un to reprezentāciju mūsdienu tekstos. …
Partial data inverse problems and simultaneous recovery of boundary and coefficients for semilinear elliptic equations
2021
We study various partial data inverse boundary value problems for the semilinear elliptic equation $\Delta u+ a(x,u)=0$ in a domain in $\mathbb R^n$ by using the higher order linearization technique introduced in [LLS 19, FO19]. We show that the Dirichlet-to-Neumann map of the above equation determines the Taylor series of $a(x,z)$ at $z=0$ under general assumptions on $a(x,z)$. The determination of the Taylor series can be done in parallel with the detection of an unknown cavity inside the domain or an unknown part of the boundary of the domain. The method relies on the solution of the linearized partial data Calder\'on problem [FKSU09], and implies the solution of partial data problems fo…
