Valsts papīru spiestuve un naudas kaltuve (1919-1940): izveidošana, darbība un loma poligrāfijas nozarē Latvijā
2017
Valsts papīru spiestuve un naudas kaltuve tika izveidota 1919. gadā, lai nodrošinātu Latvijas valsti ar nepieciešamajiem vērtspapīriem. Maģistra darba mērķis ir izpētīt spiestuves darbību no 1919.-1940. gadam un aprakstīt līdz šim nepētītu Latvijas vēstures jautājumu. Maģistra darba pirmajā nodaļā apskatīti valsts pirmie vērtspapīru pasūtījumi, Valstspapīru spiestuves izveidošana un pirmie tās darbības gadi. Darba otrajā nodaļā apskatīti problēmjautājumi, kas saistīti ar spiestuves darbību laika posmā no 1921. gada līdz 1940. gadam. Trešajā nodaļā analizēta Valstspapīru spiestuves loma starp valsts un privātajām spiestuvēm. Darba rezultātā tika izpētīta un aprakstīta Valstspapīru spiestuves…
One size hardly fits all
2013
This paper casts recent accomplishments in the field of Wireless MAC programmability into the emerging Software Defined Networking perspective. We argue that an abstract (but formal) description of the MAC protocol logic in terms of extensible finite state machines appears a convenient and viable data-plane programming compromise for modeling and deploying realistic MAC protocol logics. Our approach is shown to comply with existing control frameworks, and entails the ability to dynamically change the MAC protocol operation based on context and scenario conditions; in essence, move from the traditional idea of "one-size-fits-all" MAC protocol stack to the innovative paradigm of opportunistic…
Zoe Porphyrogenita and the Varangians
2019
Głównym celem tego artykułu jest przedstawienie relacji cesarzowej Zoe Porfirogenetki (978–1050) ze światem Waregów – z punktu widzenia źródeł bizantyńskich i skandynawskich. Zoe była jedną ze spadkobierczyń dynastii macedońskiej, która odcisnęła swoje piętno na historii Bizancjum w IX-XI w. Najczęściej jej związki ze Skandynawią przedstawiane są w korelacji z bytnością Haralda Hardrady, króla Norwegii w Cesarstwie Bizantyńskim. Ten punkt widzenia zawdzięczamy głównie sagom, które nie są tak wiarygodne jak materiały pisane przez bizantyńkich autorów z XI wieku, a zwłaszcza: Michała Psellosa, Michała Attaliatesa, Jana Skylitzesa – oraz Kekaumenosa. Relacje tych autorów zostały skonfrontowane…

Analytical Solution of the Richards Equation under Gravity-Driven Infiltration and Constant Rainfall Intensity
2020
In the field of soil hydrology, the Richards equation is commonly used to model water flow in unsaturated soils. The high nonlinearity of the Richards equation makes it very challenging to solve analytically for situations that are meaningful in practical applications. In this paper, an exact and simple analytical solution of the Richards equation under gravity-driven infiltration and constant rainfall intensity is derived. First, the solution is presented under Torricelli's law, which mimics the soil hydraulic conductivity function and describes the emptying or filling process of a nonlinear water reservoir. Then, following a similar approach, the solution is extended to the Brooks and Cor…
Photoinduced Modifications of the Structure and Microhardness of Fullerite C60
2004
The wavelength dependence, temperature limits, time and depth evolution of the photoinduced hardening of C60 crystals in air have been investigated by microindentation and dislocation mobility methods. Two photopolymerized phases, which differ in the hardness and thermal stability, are found to appear. We suggest that formation of fullerene dimers (ie. C120) in pristine fullerite and growth of C120O phase in oxygenated fullerite via [2+2] photoaddition reaction is responsible for it. It has been found from depth distribution data of the hardness that the C120O phase is located in oxygen-contaminated subsurface layer of 0.8–1 μm and appears under illumination at 290–330 K.
Gaussian quadrature rule for arbitrary weight function and interval
2005
Abstract A program for calculating abscissas and weights of Gaussian quadrature rules for arbitrary weight functions and intervals is reported. The program is written in Mathematica. The only requirement is that the moments of the weight function can be evaluated analytically in Mathematica. The result is a FORTRAN subroutine ready to be utilized for quadrature.

Ireland Computer for which the program is designed and others on which it has been tested: Computers: Pentium IV 1.7 GHz processor Ins…
City gates of Augustodunum and their architectural models (Gaul, Italy, Western Provinces of the Roman Empire)
2012
Augustodunum, civitas Aeduorum, roman city founded under the reign of Augustus, was equipped with four roman city gates : the gate of Arroux and the gate of Saint André, both well preserved, the gate of Saint Andoche which sole remaining part is a flanking tower, and the gate of Rome, destroyed long ago.The heart of this study lies in the stratigraphic reading of those gates structure and in thoughts about the building site of Autun’s city gates operating process. Moreover, since the 16th century, antiquaries, travelers and artists have described in many ways their visits to the roman city gates of Autun. These accounts constitute a major documentary collection of written and iconographical…
Sensory and chemical drivers of wine minerality aroma: An application to Chablis wines
2017
The goal of this work was to evaluate the effect of vineyard position on the minerality of wines and to establish relationships between minerality scores, sensory descriptors and chemical composition. Sensory analyses included minerality rating and free description performed by wine professionals under two conditions: orthonasal olfaction alone and global tasting. Chemical characterization included analysis of major and minor volatile compounds, volatile sulphur compounds, mercaptans, metals, anions and cations. Results showed a significant effect of the river bank on wine minerality scores only in the orthonasal olfaction condition, samples from the left being more mineral than those from …
