Ergonyms of Educational and Cultural spheres in two of Baltic States cities
2020
Daugavpils (Latvia) and Narva (Estonia) are cities in the Baltic States and signifi cant cultural and economic centres of their respective countries. These cities are characterized by a minority of nationals (19.8% of residents of Daugavpils are Latvian, 4% of residents of Narva are Estonian) and a similar linguistic situation: there is a dominance of Russian in the press, television and radio, but the state language prevails in the urban language signs.The aim of the study is to analyse the linguistic and extralinguistic means used for the creation of ergonyms of educational and cultural spheres. The main criteria for the analysis are: language choice, grammatical structures, sources of pr…
A comparison study of evolutive algorithms for solving the partitioning problem in distributed virtual environment systems
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad hoc heuristic proposed in the literature. Performance evaluation results show that some…
Theatrical virtual acoustic rendering with head movement interaction
2019
AbstractNowadays, the use of virtual reality/virtual acoustics (VR/VA) in archaeology for rendering lost buildings is an important topic in the cultural heritage field. Moreover, the addition of additional senses apart from the sight increases the feeling of immersion in virtual environments. The aim of this paper is to show the interaction work developed in a VA system, based on Unity and FMOD, the graphical and acoustical reconstruction of an ancient building and the development of a VR goggles with headphones to render 3D audio and video interactively. This system has been implemented to render auralizations in a binaural system and has been applied to the renderization of an old and los…
A Comparison Study of Modern Heuristics for Solving the Partitioning Problem in Distributed Virtual Environment Systems
2003
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad-hoc heuristic proposed in the literature. Performance evaluation results show that som…
Combined Endo- and Exoscopic Semi-robotic Manipulator System for Image Guided Operations
2006
This paper describes the development of a robotic assistance system for image guided operations. To minimize operation time, a multimodal user interface enables freehand robotic manipulation of an extracorporeal stereoscopic digital camera (exoscope) and an endoscope. The surgeon thereby wears a head-mounted unit with a binocular display, a head tracker, a microphone and earphones. Different view positioning and adjustment modes can be selected by voice and controlled by head rotation while pressing a miniature confirmation button with a finger. Initial studies focused on the evaluation and optimization of the intuitiveness, comfort and precision of different modes of operation, including a…
The origin, definition and nature of the transconscious in the spirituality of Father Stăniloae
2022
In his important work, Orthodox Spirituality , Father Dumitru Staniloae considers that, besides the real existence of the subconscious, there exists in man another reality as well, comprising the superior divine energies found in the human heart and which he defined by using the modern notion of transconscious or supraconscious. Contribution: The present study emphasises on the origin, definitions and content of this concept in the work of Father Staniloae and its great importance in defining a way to know God and his salvation works, from the perspective of an anchorite and Christian mystic, engaged in the existential tension of communion with God.
PRUDENTE GOBIERNO: LA PRUDENCIA EN EL GOBERNANTE
2019
Partiendo de las fuentes filosoficas y literarias, la Prudencia es considerada la principal virtud que debe poseer todo gobernante. Esta relacion propicio la interaccion visual entre la figura del gobernante y la imagen de la Prudencia. De este modo, en ocasiones, la Prudencia, adquiere atributos propios del gobernante, asi como este adquiere los de la Prudencia, retratandose incluso como esta virtud.
CHA on CDK2: a way to identify the best pharmacophore model for the virtual screening of new inhibitors
2018
Cyclin-dependent kinase-2 (CDK2) is a member of serine/threonine protein kinases family. It plays an important role in the regulation events of the eukaryotic cell division cycle, especially during the G1 to S phase transition. Experimental evidences indicate that excessive expression of CDK2 should cause abnormal cell cycle regulation. Therefore, CDK2 has been considered a potential therapeutic target for cancer therapy. In this work, we used a modelling approach that incorporates flexibility based on extensive MD simulations of protein−ligand complexes into structure-based pharmacophore modeling and virtual screening to identify new CDK2 inhibitors. One-hundred and forty-nine CDK2-inhibit…
Cnoty jako dyspozycje psychiczne i ich wpływ na jakość życia współczesnego człowieka
2015
his paper explores the problem of virtue, understood as a mental disposition and its impact on the existence of human subject. The concepts of virtues developed by philosophers over the different eras are now the inspiration for psychology, mostly positive psychology. The aim of this analysis is to verify the hypothesis of a relationship between the possession of specific virtues and a sense of the quality of life. The research method is based on an analysis of the literature. The research material consists of the latest publications of leading psychologists, experts in the field of positive psychology, Polish and foreign, and an extensive literature in the field of philosophy. Based on the…
Research-based reflections about character education: myths, challenges and international perspectives
2018
At present, youngsters’ character and virtue education issues are widely discussed in Latvia and in English-speaking academic environment. Given the existing criticism of these concepts, the research question was: what are the main misunderstandings about the nature of character and virtue education? After clarifying the neo-Aristotelian understanding of these concepts, recent research in the field of character education and virtues is presented for deconstructing some of the myths related to it, due to conceptual, historical, moral and political misunderstandings (Kristjánsson, 2013). Real problems (historical, methodological and practical) faced by character education programs in mainstre…
