Speciālās leksikas tulkošanas problēmas galda lomu spēlē ''Dungeons and Dragons''

2018

Maģistra darbā “Speciālās leksikas tulkošanas problēmas galda lomu spēlē Dungeons & Dragons” aplūkota spēlē Dungeons & Dragons sastopamā speciālā leksika un ar tās tulkošanu saistītās problēmas. Darba teorētiskajā daļā ir apkopota informācija par jēdzienu “spēle” un vairākiem spēļu veidiem, sniegts ieskats spēles Dungeons & Dragons vēsturē un tās galvenajos elementos, kā arī apkopota informācija par speciālo leksiku un tai atbilstošajām tulkošanas stratēģijām. Darba praktiskajā daļā ir analizēts autores piedāvātais spēlētāja tēla raksturojuma terminu tulkojums un aprakstītas darba gaitā novērotās tulkošanas problēmas.

How to boost clusters and regional change through cooperative social innovation

2020

The aim of this paper is to illustrate how social innovation is promoted and spread by cooperative clusters in order to develop regional change. This paper focuses on the main drivers of the spreading and exaptation processes of social innovation. The cooperative cluster model, the exaptation concept, the top-down approach, the meso-institutions concept and the meso-level perspective are used to capture the strategic approach of spreading social innovation. The study analyses two successful clusters: Mondragon, made up of industrial SMEs, and Anecoop, an agricultural cooperative group, both leading clusters in their respective region. Qualitative methodology is used to compare both case stu…

Take-off aerodynamics in ski jumping

2001

The effect of aerodynamic forces on the force-time characteristics of the simulated ski jumping take-off was examined in a wind tunnel. Vertical and horizontal ground reaction forces were recorded with a force plate installed under the wind tunnel floor. The jumpers performed take-offs in non-wind conditions and in various wind conditions (21-33 m s(-1)). EMGs of the important take-off muscles were recorded from one jumper. The dramatic decrease in take-off time found in all jumpers can be considered as the result of the influence of aerodynamic lift. The loss in impulse due to the shorter force production time with the same take-off force is compensated with the increase in lift force, res…

A preliminary method for the numerical prediction of the behavior of air bubbles in the design of Air Cavity Ships

2016

Air-cavity ships (ACS) are advanced marine vehicles that use air injection under hull to improve the vessel’s hydrodynamic characteristics. Although the concept of drag reduction by supplying gas under the ship’s bottom was proposed in the 19th century by Froude and Laval, at this time there are not many systematic studies on this subject. This paper is a preliminary work with the purpose of being a basic tool for the design of the ACS with computational fluid dynamic methods. The study aims to conduct a series of computational tests to compare the numerical models of bubble with experimental data. The first step of this study was to investigate the behavior of free bubble in water, conside…

CFD simulations of dense sloid-liquid suspensions in baffled stirred tanks: Prediction of suspension curves

2011

Mixing of solid particles into liquids within contactors mechanically agitated by stirrers is a topic of primary importance for several industrial applications. A great research effort has been devoted to the assessment of the minimum impeller speed (Njs) able to guarantee the suspension of all particles. Conversely, only little attention has been paid so far to the evaluation of the amount of solid particles that are suspended at impeller speeds lower than Njs. In some cases the loss in available interfacial area between particles and liquid could be reasonably counterbalanced by a decreased mechanical power, making it of interest to evaluate the percentage of suspended solids at different…

UAQ4 Levitating Train: Italian Maglev Transportation System

2014

This article illustrates the University of L'Aquila model 4 (UAQ4) Italian maglev train, a transportation system with zero motion resistance (except aerodynamic drag) and greatly reduced energy consumption, approaching zero at a low constant speed. The project is the result of more than 40 years of research in the field of nonconventional highspeed transportation systems. Its technological feasibility has been tested in the laboratory at the University of L'Aquila, Italy.
