Seasonal Changes in Urban PM2.5 Hotspots and Sources from Low-Cost Sensors

2022

PM2.5 concentrations in urban areas are highly variable, both spatially and seasonally. To assess these patterns and the underlying sources, we conducted PM2.5 exposure measurements at the adult breath level (1.6 m) along three ~5 km routes in urban districts of Mainz (Germany) using portable low-cost Alphasense OPC-N3 sensors. The survey took place on five consecutive days including four runs each day (38 in total) in September 2020 and March 2021. While the between-sensor accuracy was tested to be good (R² = 0.98), the recorded PM2.5 values underestimated the official measurement station data by up to 25 µg/m3. The collected data showed no consistent PM2.5 hotspots between September and M…

APPLICAZIONE DI CRITERI E INDICATORI DELLA CERTIFICAZIONE PEFC DI GESTIONE FORESTALE SOSTENIBILE: DUE CASI STUDIO A CONFRONTO NEL TERRITORIO SICILIANO

2018

La Sicilia non ha ancora complessi forestali la cui gestione sostenibile sia stata certificata. Questo lavoro è volto a analizzare la possibilità di applicare i criteri e indicatori di certificazione di GFS secondo lo schema PEFC a due casi studio: i boschi del comune di Bivona (AG) e una foresta situata sulle Madonie (PA). Entrambi sono rappresentativi di ambienti ecologici diversi e importanti dell’isola. L’analisi pone in luce le criticità più significative della gestione attualmente adottata e la mancanza di comunicazione con i portatori d’interesse. Application of Criteria and Indicators of Sustainable Forest Management PEFC Certification: two case studies in Sicily Sicily currently ha…

Radio environment map estimation based on communication cost modeling for heterogeneous networks

2017

Los mapas del entorno radioeléctrico pueden ser una poderosa herramienta para lograr una asignación de recursos eficiente y consciente del contexto en las redes heterogéneas 5G. En este trabajo, consideramos una red heterogénea formada por una red celular tradicional y una red de sensores inalámbricos. El papel de la red de sensores inalámbricos es estimar el mapa del entorno radioeléctrico de la célula utilizando una técnica de interpolación geoestadística denominada Kriging. En un trabajo anterior se propuso un algoritmo de agrupación distribuida de sensores para reducir la complejidad de la estimación. En nuestra contribución, el proceso de formación de clústeres se modifica para incluir…

Distributed radio map reconstruction for 5G automotive

2018

Se espera que los mapas de entorno radio sean una herramienta esencial para la optimización y gestión de recursos del 5G en vehículos. En este trabajo, consideramos el problema de la reconstrucción del mapa de entorno radio utilizando una red de sensores inalámbricos formada por nodos sensores en vehículos, nodos de acceso de una infraestructura de ciudad inteligente, etc. Debido a las limitaciones de recursos en las redes de sensores, es crucial seleccionar un pequeño número de mediciones de los sensores para reconstruir el campo. En este contexto, presentamos un novedoso algoritmo distribuido basado en el método de regresión Kriging para la reconstrucción del mapa de entorno radio en térm…

Aprendizaje móvil de lenguas basado en criterios pedagógicos

2015

[ES] El MALL (Mobile Assisted Language Learning) aporta una inmensa cantidad de aplicaciones de aprendizaje de lenguas. En este contexto es necesario que el triple proceso de análisis, evaluación y desarrollo de aplicaciones de MALL cumpla con dos premisas fundamentales. En primer lugar, debe llevarse a cabo a partir de criterios pedagógicos específicos del aprendizaje de lenguas. En segundo lugar, debe apoyarse en modelos teóricos que consideren el proceso de enseñanza-aprendizaje de lenguas. Este trabajo se enmarca dentro de una investigación más general que propone una metodología para el análisis, evaluación y desarrollo pedagógico de aplicaciones móviles de aprendizaje de lenguas, segú…

High precision measurement of Gamma(Z->bbbar)/Gamma(Z->hadrons) with the DELPHI detector at LEP collider

1997

Entre las medidas disponibles a la energía en centro de masas correspondiente al polo del bosón Z, la fracción de la anchura parcial a pares de quarks bbbar y su anchura parcial hadrónica, Rb0 = Gamma(Z -> bbbar) / Gamma(Z -> hadrones),tiene actualmente un especial interés. Prácticamente todas las correcciones radiativas electrodébiles y de QCD cancelan al realizar el cociente, de forma que Rb0 es esencialmente sensible sólo a las correcciones al vértice Z -> bbbar, como el fuerte acoplamiento CKM al quark top. Dado el excelente acuerdo entre el Modelo Estándar y la mayor parte de las observaciones de precisión, junto con el reciente descubrimiento del quark top y la determinación directa d…

"Mani gadi uz mani neattiecas": Jura Cālīša jubilejas izstāde

2019

Lai atzīmētu nozīmīgo dzīves jubileju un apzinātu Jura Cālīša personības plašumu, Latvijas Universitātes Bibliotēka izveidoja Jura Cālīša jubilejas izstādi. Izstādes radošā komanda izskatīja 240 publikācijas, kurās izskanējušas Jura Cālīša domas par dažādiem tematiem. Paralēli bibliogrāfijai klasiskā izpratnē tapa domu un atziņu bibliogrāfija, kas materializējusies izstādē. Darba gaitā izkristalizējās četras ietilpīgas tēmas – dzīve, cilvēks, ticība un mīlestība, kas ļāva sagrupēt domu graudus. Kopumā tika atlasīti 99 citāti, kas atspoguļoti ne tikai planšetēs, bet arī grāmatzīmēs

Efficacy of an internet-based psychological intervention for problem gambling and gambling disorder: study protocol for a randomized controlled trial

2021

Gambling Disorder is a prevalent non-substance use disorder, which contrasts with the low number of people requesting treatment. Information and Communication Technologies (ICT) could help to enhance the dissemination of evidence-based treatments and considerably reduce the costs. The current study seeks to assess the efficacy of an online psychological intervention for people suffering from gambling problems in Spain. The proposed study will be a two-arm, parallel-group, randomized controlled trial. A total of 134 participants (problem and pathological gamblers) will be randomly allocated to a waiting list control group (N = 67) or an intervention group (N = 67). The intervention program i…
