Successive Reduction of Arms in Multi-Armed Bandits
2011
The relevance of the multi-armed bandit problem has risen in the past few years with the need for online optimization techniques in Internet systems, such as online advertisement and news article recommendation. At the same time, these applications reveal that state-of-the-art solution schemes do not scale well with the number of bandit arms. In this paper, we present two types of Successive Reduction (SR) strategies - 1) Successive Reduction Hoeffding (SRH) and 2) Successive Reduction Order Statistics (SRO). Both use an Order Statistics based Thompson Sampling method for arm selection, and then successively eliminate bandit arms from consideration based on a confidence threshold. While SRH…
Regioninės kultūros samprata rengiant mokytojus Latvijoje, Lietuvoje ir Norvegijoje: lyginamoji atvejo analizė.
2019
Straipsnyje nagrinėjama regionų kultūra, regioninių tradicijų svarba, siekiant šalies kultūrinio tvarumo. Vis dėlto regioninių tradicijų puoselėjimas dažnai laikomas kliūtimi globalizacijai ir daugiakultūriškumui. Kyla klausimas: kaip apsaugoti ir plėtoti regionų kultūrinę įvairovę, kultūros paveldą? Mokytojų rengimui tenka svarbi misija ‒ plėtoti idėjas apie regioninės kultūros svarbą, inicijuoti jos išsaugojimą bei ieškoti jungčių tarp regioninio ir globalaus konteksto. Tyrimu siekiama nustatyti, kokie faktoriai skatina arba trukdo plėtoti būsimųjų mokytojų kompetencijas, kurios leistų sėkmingai ugdyti pradinės mokyklos mokinių regioninės kultūros supratimą. Lyginamoji trijų šalių (Latvij…

The status of dental caries and related factors in a sample of Iranian adolescents.
2010
Objective: To describe the status of dental caries in a sample of Iranian adolescents aged 14 to 18 years in Qazvin, and to identify caries-related factors affecting this group. Study design: Qazvin was divided into three zones according to socio-economic status. The sampling procedure used was a stratified cluster sampling technique; incorporating 3 stratified zones, for each of which a cluster of school children were recruited from randomly selected high schools. The adolescents agreed to participate in the study and to complete a questionnaire. Dental caries status was assessed in terms of decayed teeth (DT), filled teeth (FT) and decayed, missing and filled teeth (DMFT). A multivariate …
Quantitative Estimation of Major and Trace Elements in Coals of the Benue Trough, Nigeria
2013
The concentrations of major and trace elements in ash residues of coals of the Benue Trough, Nigeria have been determined by electron microprobe and laser ablation-inductively coupled plasma-mass spectrometry, respectively. Major and trace element determination in rocks by fusion on an iridium strip heater followed by electron microprobe and laser ablation-inductively coupled plasma-mass spectrometry is extended here to coal ash, and the accuracy of the method is evaluated by including an Argonne Premium Coal reference sample in each analysis program. Si and Al are the major elements detected in the coal ashes. An assessment using worldwide concentration ranges of trace elements in coal ash…
Reliability results of straylight measurements using the C-Quant
2008
Purpose Assessment of repeatability and reproducibility of straylight measures with the C-Quant straylightmeter (Oculus AG, Germany), effect of age on reliability measures and correlation of measures determined with new methods of scatter determination. Methods Results from different studies will be presented. For repeatability assessment, 20 eyes (age 26.9±2.7 years) were examined with the C-Quant, taking 10 consecutive readings. 5 subjects were also examined on 5 consecutive days to assess reproducibility. Repeated measures from 84 subjects, age range 19-86 years, were analysed to assess the effect of patient’s age. Software was developed to quantify scatter from centroid patterns obtaine…
Trace analysis by ion mobility spectrometry: From conventional to smart sample preconcentration methods. A review.
2018
Ion mobility spectrometry (IMS) is a rapid and high sensitive technique widely used in security and forensic areas. However, a lack of selectivity is usually observed in the analysis of complex samples due to the scarce resolution of the technique. The literature concerning the use of conventional and novel smart materials in the pretreatment and preconcentration of samples previous to IMS determinations has been critically reviewed. The most relevant strategies to enhance selectivity and sensitivity of IMS determinations have been widely discussed, based in the use of smart materials, as immunosorbents, aptamers, molecularly imprinted polymers (MIPs), ionic liquids (ILs) and nanomaterial. …
The rationality of acceptance in a nuclear community: analysing residents' opinions on the expansion of the SNF repository in the municipality of Eur…
2010
The project to build a final disposal repository for Spent Nuclear Fuel (SNF) in the municipality of Eurajoki, Finland, is approaching its 2012 deadline for the application of a construction licence. At the same time, the nuclear waste company Posiva is already planning to expand the disposal capacity of the repository. This paper addresses the question of acceptance among the residents of Eurajoki regarding the repository's expansion, and examines what aspects should be taken into consideration when explaining local opinions. The local acceptance figures for Eurajoki are analysed in relation to assumptions of the six common explanation types. The relationship between information deficit, s…

Architettura termoelettrica. L’immaginario e il progetto nella centrale di Giuseppe Samonà ad Augusta
2016
Nel 2015, ha avuto inizio il processo di dismissione della centrale termolelettrica progettata a Augusta (Sicilia) da Giuseppe Samonà. Inquadrando l'origine dell'architettura delle centrali elettriche all'interno della relazione antinomica e simbolica tra la macchina, l'elettricità, la fabbrica e l'arte che l'Europa occidentale ha elaborato a partire dalla fine del XX secolo, questo articolo discute quindi i principali caratteri architettonici delle Centrale di Augusta. Poi, considera le nuove prospettive da affrontare per le centrali termoelettriche nella transizione verso i nuovi principi della sostenibilità. Ogni potenziale di queste zone di produzione dovrebbe essere riconsiderato, e tu…
