Parallelization of adaptive MC integrators

1997

Monte Carlo (MC) methods for numerical integration seem to be embarassingly parallel on first sight. When adaptive schemes are applied in order to enhance convergence however, the seemingly most natural way of replicating the whole job on each processor can potentially ruin the adaptive behaviour. Using the popular VEGAS-Algorithm as an example an economic method of semi-micro parallelization with variable grain-size is presented and contrasted with another straightforward approach of macro-parallelization. A portable implementation of this semi-micro parallelization is used in the xloops-project and is made publicly available.

Uzvedības maiņas metožu pielietojums Zero-Waste dzīvesveida aktualizēšanā

2020

Cilvēku ikdienas izvēļu un darbību rezultātā atkritumu daudzums un vides piesārņojums nepārtraukti palielinās. Tā rezultātā notiek izmaiņas ekosistēmās, tiek samazināta bioloģiskā daudzveidība, veicināta slimību, kaitēkļu un invazīvo sugu izplatība, kā arī tiek apdraudēta daudzu sugu eksistence un veicinātas klimata pārmaiņas. Zero waste stratēģija ir viens no iespējamiem risinājumiem. Tā vērsta uz resursu patēriņa samazināšanu, sabiedrības virzīšanu uz ekoloģiski atbildīgāku un ilgtspējīgāku dzīvesveidu, kā arī cilvēku negatīvās ietekmes uz vidi maksimālu samazināšanu. Bakalaura darba mērķis ir analizēt uzvedības maiņas metožu ietekmi uz bezatkritumu dzīvesveida stratēģijas izplatību sabie…

Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes.

2021

The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey con…

Associations between private speech, behavioral self-regulation, and cognitive abilities

2014

We examined the associations between 5-year-old children’s private speech, behavioural self-regulation, and cognitive abilities. Behavioural self-regulation was assessed using parental and preschool teacher questionnaires. Cognitive abilities (i.e., language, inhibition, planning and fluency, and memory) were assessed with neurocognitive tests, and the effectiveness of private speech (i.e., whether the child performs better when using speech than when not using speech) with the Hammer Task. About 43% of the children used private speech spontaneously, and about 76% performed better on the Hammer Task when they used speech. Associations between behavioural self-regulation and speech effectiv…

Development of pre-academic skills and motivation in kindergarten : a subgroup analysis between classroom quality profiles

2017

AbstractThe present study extends research on classroom quality profiles by examining the differences between profiles with respect to children’s development in pre-academic skills and motivation across the kindergarten year. Teacher–child interactions were observed in 49 Finnish kindergarten classrooms using the CLASS Pre-K instrument. Based on prior identification of latent profiles of classroom quality, subgroup analyses on children’s data were carried out on three profiles representing high Emotional Support and Classroom Organisation and intermediate Instructional Support (Profile 1), higher-intermediate Emotional Support and Classroom Organisation and lower-intermediate Instructional …

Modelling the Water Retention Domain of a Compacted Scaly Clay

2012

A body of experimental data on the water retention behaviour of compacted samples of an Italian scaly clay is analysed. The mechanical and the hydraulic behaviour of compacted samples of this clay are governed by multi-scale arrangement of scales and aggregates, which characterises the compacted clay fabric. At least two different pore networks, namely intra-aggregate and inter-aggregate, may be identified, which interact one with the other along coupled hydro-mechanical paths. The retention behaviour is interpreted in the framework of a comprehensive multi-scale modelling approach recently proposed for compacted clays of low and medium activity, which proves to be able to account for the i…

Two interconnected functional systems in the amygdala of amniote vertebrates.

2008

The amygdala shows ventropallial and lateropallial derivatives that can be compared among vertebrates according to their topological position, either superficial (cortical amygdala) or deep (basolateral amygdala and amygdalo-hippocampal area), connections and histochemical features. On the other hand, the subpallial amygdala, also called extended amygdala, is composed of medial and central divisions. In mammals, both divisions consist of an intra-amygdaloid portion and a part of the bed nucleus of the stria terminalis. In non-mammals, the intratelencephalic trajectory of the stria terminalis is short and both poles of the extended amygdala are close together. Like its mammalian counterpart,…

Walking tourism in Malaga: a pilot survey to explore tourism behaviours with a GPS approach

2018

Walking tourism in urban destinations can be defined as a sequence of day visits and/or a sequence of walking tours. In this work, GPS tracking data on spatio-temporal behaviour of walking tourists in Malaga are reported as case study. Malaga is a booming tourist destination characterized by a city centre, particularly suitable for a pedestrian visit. From 22nd January to 19th March 2018 for a total period of 41 days, a survey was carried out with a specific protocol: 103 interviews were conducted and 101 GPS valid tracks were collected. Walking tourists were systematically sampled, starting from the population of all tourists staying in the surveying day at some selected hotels in the city…
