Informācijas sistēmas papildinājums telpisko objektu meklēšanai

2021

Kvalifikācijas darbā izstrādāts ģeogrāfiskās informācijas sistēmas papildinājums telpisko objektu meklēšanai. Sistēmas papildinājuma mērķis - atvieglot sistēmas lietotāju darbu, kā arī paaugstināt produktivitāti, ieekonomējot laiku objektu meklēšanai. Sistēmas papildinājuma galvenās funkcijas ir atrast tuvāko telpisko objektu noteiktajās koordinātēs, piemēram, transformatoru, balstu vai elektrolīniju, izdrukāt atrastā objekta atrašanās vietas koordinātes, kā arī objekta identifikatora numuru. Sistēmas papildinājums ir radīts AS “Latvenergo” elektrisko sadales tīklu ģeogrāfisko informāciju sistēmai un to izmantos ĢIS lietotāji un pieslēgumu plānošanas inženieri.

Quantitative Data on Petunia Embryogenesis: Mitotic Activity and Characteristics of the Cell Cycles

1988

The studies on the embryonal development of Angiosperms are essentially descriptive and some quantitative data are only available at the present time. Within Dicotyledons, one must mentioned the works of Rietsema and al. (1955) on the growth of ovules and embryos of Datura stramonium, the interesting comparison between the growth of Capsella and Gossypium embryos effected by Pollock and Jensen (1964), the studies of Simoncioli (1974) and Tykarska (1980) on two Brassicaceae, respectively Diplotaxis erucoides and Brassica napus, and the work of Gray and al. (1984) on the embryo development of Daucus carota.

Some qualitative properties for the total variation flow

2002

We prove the existence of a finite extinction time for the solutions of the Dirichlet problem for the total variation flow. For the Neumann problem, we prove that the solutions reach the average of its initial datum in finite time. The asymptotic profile of the solutions of the Dirichlet problem is also studied. It is shown that the profiles are nonzero solutions of an eigenvalue-type problem that seems to be unexplored in the previous literature. The propagation of the support is analyzed in the radial case showing a behaviour entirely different to the case of the problem associated with the p-Laplacian operator. Finally, the study of the radially symmetric case allows us to point out othe…

Elliptic equations having a singular quadratic gradient term and a changing sign datum

2012

In this paper we study a singular elliptic problem whose model is \begin{eqnarray*} - \Delta u= \frac{|\nabla u|^2}{|u|^\theta}+f(x), in \Omega\\ u = 0, on \partial \Omega; \end{eqnarray*} where $\theta\in (0,1)$ and $f \in L^m (\Omega)$, with $m\geq \frac{N}{2}$. We do not assume any sign condition on the lower order term, nor assume the datum $f$ has a constant sign. We carefully define the meaning of solution to this problem giving sense to the gradient term where $u=0$, and prove the existence of such a solution. We also discuss related questions as the existence of solutions when the datum $f$ is less regular or the boundedness of the solutions when the datum $f \in L^m (\Omega)$ with …

Symmetrization for singular semilinear elliptic equations

2012

In this paper, we prove some comparison results for the solution to a Dirichlet problem associated with a singular elliptic equation and we study how the summability of such a solution varies depending on the summability of the datum f. © 2012 Fondazione Annali di Matematica Pura ed Applicata and Springer-Verlag.

Existence and comparison results for a singular semilinear elliptic equation with a lower order term

2014

This paper deals with the homogeneous Dirichlet problem for a singular semilinear elliptic equation with a first order term. When the datum is bounded we prove an existence result and we show that any solution can be compared with the solution to a suitable symmetrized problem.

Nomination for inscription on the World Heritage List Unesco. Arab-Norman Palermo and cathedral churches of Cefalù and Monreale

2012

Il dossier di candidatura per l'iscrizione nella WHL rappresentano l’insieme degli edifici costituenti l’itinerario arabo normanno rappresentano un eccezionale valore universale come esempio di convivenza e interazione tra diverse componenti culturali di provenienza storica e geografica eterogenea (sincretismo culturale). Tale fenomeno ha generato uno stile architettonico originale in cui sono mirabilmente fusi elementi bizantini, islamici e romanici, capace di volta in volta di prodursi in combinazioni uniche, di eccelso valore artistico e straordinariamente unitarie
