Attēlu saspiešanas algoritmi
2015
Darbā tiek aprakstīti izmantotākie attēlu saspiešanas algoritmi un failu formāti, kas satur dažādos saspiešanas algoritmu kombinācijas. Gan algoritmi, gan attēlu formāti tiek salīdzināti savā starpā ar dažādiem kritērijiem bezzudumu un zudumu algoritmiem. Salīdzināšanai tiek izmantotas autora rakstītas algoritmu realizācijas MATLAB valodā un attēlu apstrādes programma attēlu formātu veidošanā. Tiek veikti secinājumi par algoritmu efektivitāti – ātrdarbību, saspiešanas spējām un attēla kvalitātes izmaiņām.
Latvijas iedzīvotāju subjektīvā labklājība un tās neseno izmaiņu analīze
2020
Katru gadu valsts politikas izstrādē un budžeta līdzekļu pārdalē ir aktuāls jautājums par prioritātēm. Ja valsts politikas stratēģiskais mērķis ir laimīgāki Latvijas iedzīvotāji, tad ir nepieciešams saprast, kādi faktori ietekmē Latvijas iedzīvotāja laimi jeb subjektīvo labklājību, lai pēc iespējas efektīvāk izlietotu budžeta līdzekļus. Balstoties uz Eiropas Savienības Ienākumu un dzīves apstākļu 2013. un 2018. gada apsekojuma rezultātiem par Latvijas iedzīvotājiem, un izmantojot lineārās regresijas mazāko kvadrātu metodi un Stata datorprogrammu, pētījumā tiek identificēti galvenie Latvijas iedzīvotāju laimes (subjektīvās labklājības) faktori. Šie faktori ir veselības stāvoklis, ienākumi un…

Enseñar E/LE a la primera generación de nativos digitales
2017
Resumen: Este artículo trata de la primera generación de verdaderos nativos digitales en Europa, nacidos en torno al año 2000 y que en la actualidad asisten a los institutos de secundaria. Son diferentes a los de generaciones anteriores debido sobre todo al impacto que la tecnología ha tenido en sus vidas, pero la mayoría sigue sistemas educativos desfasados, diseñados para alumnos del siglo pasado. Muchos profesores intentan adaptarse a la nueva situación incorporando las TIC en sus cursos. La autora analiza el proceso de creación de un telediario, actividad realizada en el marco de un proyecto piloto de uso de los Ipad en los cursos de E/LE. Este proyecto obtuvo el Primer Premio del concu…
Diverse societies are more productive: a lesson from ants
2012
The fitness consequences of animal personalities (also known as behavioural syndromes) have recently been studied in several solitary species. However, the adaptive significance of collective personalities in social insects and especially of behavioural variation among group members remains largely unexplored. Although intracolonial behavioural variation is an important component of division of labour, and as such a key feature for the success of societies, empirical links between behavioural variation and fitness are scarce. We investigated aggression, exploration and brood care behaviour in Temnothorax longispinosus ant colonies. We focused on two distinct aspects: intercolonial variabil…
E-Fairs: a Cyber-Physical System for Aggregation and Economy of Scale in e-Commerce
2018
In recent years, the e-commerce arena has deeply changed because of the advent of new business models and the growing weight of huge global actors like Amazon. Some business models create competition between users, and the product price tends to rise (e.g., online auctions); other models, including group-buying, make users cooperate, and the price tends to go down. The present study extends the group-buying model and proposes a cyber-physical system called e-fair, in which both sellers and buyers are grouped to negotiate on a specific product or service. E-fairs minimize the global purchase price and the shipping resources respectively with the aggregation of demand and supply as well as or…
Institutional Functions as a Theoretical Nexus and Measurement Target in Sociology of Education
2017
The paper is devoted to methodological aspects of the study of institutional functions of education as one of the basic theoretical constructs of contemporary sociology of education. The author argues that the elaboration into the function problem also provides a direction for social-practical outputs of this branch of sociology, conceptual ground for its own theoretical, revitalizing its connection with general sociology. Without such elaboration, the author assumes, most of theoretical and empirical studies and measurements conducted by sociologists are doomed to thematic fragmentation, have slim chances to contribute to a shared sociological vision of education, delineate the area of ins…
La inserción laboral de los inmigrantes italianos en Valencia durante la crisis
2018
España ha pasado de una fase de intensa inmigración internacional durante el período de crecimiento económico a otra de re-emigración y retornos de extranjeros (y de emigración de nativos) durante la recesión. En nuestra investigación hemos observado una tendencia opuesta: durante la crisis se ha incrementado significativamente la llegada de inmigrantes procedentes de Italia a la ciudad de Valencia. Se trata de personas económicamente activas, con intención de permanencia, cualificadas y procedentes de regiones con indicadores socioeconómicos superiores a los de la Comunidad Valenciana. Por consiguiente, el análisis de su inserción laboral es clave para explicar las causas de la migración. …
Trait driving anger and driving styles among Colombian professional drivers
2019
Abstract This study analyzes the association between trait driving anger and driving styles in a sample of Colombian professional drivers. Additionally, the internal and external validity of the Deffenbacher's Driving Anger Scale (DAS-14) was examined in the study population. The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent stru…
From Solid Spaces To Liquid Spaces: New Ecologies of Musical Practices.
2019
Purpose: In recent years, the interest in creating new educational spaces has increased substantially, aiming to influence the methods of learning of our students and to adopt new educational strategies. This article highlights the importance of the atmosphere when remodeling musical practices. Methodologically, when transforming a space, we do not only have to improve the physical architectures but also the pedagogical ones, as well as keeping the practices consistent with these changes. The MUSICLAB CR-209 'Sound laboratory' have been built in Valencia (Spain). This is a hybrid space designed especially for collaborative projects -teachers, artists, students and researchers- in which soun…
