Municipal Integrated Coastal Management Facilitation in Latvia: Piloting Public Multi-Thematical Monitoring
2021
This paper contains a pilot study on coastal values and potential means of determining and characterising them in the terms of coastal planning and management. The research case study took place in the coastal region of North East Latvia – in the municipality of Salacgriva. The municipality coast is very diverse: coastal access, landscape and the whole biogeography is changing very much along the whole 54 km, being also rich in various natural and cultural heritage assets. Such great coastal variety in the limits of one administrative territory does require very selective governance approaches and dynamic management to be realized by local administration, which has very limited necessary ca…
Estrategias emocionales en educación física a través del aprendizaje servicio: aplicación del programa siente jugando en alumnado de primaria
2019
Las emociones, la inteligencia emocional y la competencia socioemocional son algunos de los contenidos transversales que podemos desarrollar desde la Educación Física escolar. El juego motor es una fuente de estímulos y vivencias que favorece el desarrollo de las estructuras físicas y cerebrales que el alumnado de Primaria utilizará en su presente y futuro. El objeto de este estudio fue analizar las estrategias utilizadas para la resolución de conflictos tras la puesta en práctica de un programa de intervención denominado “Siente Jugando”, haciendo uso de la metodología Aprendizaje Servicio. La muestra estuvo formada por 93 participantes de Educación Primaria Obligatoria (EPO), de edades co…
Deep Completion Autoencoders for Radio Map Estimation
2022
Radio maps provide metrics such as power spectral density for every location in a geographic area and find numerous applications such as UAV communications, interference control, spectrum management, resource allocation, and network planning to name a few. Radio maps are constructed from measurements collected by spectrum sensors distributed across space. Since radio maps are complicated functions of the spatial coordinates due to the nature of electromagnetic wave propagation, model-free approaches are strongly motivated. Nevertheless, all existing schemes for radio occupancy map estimation rely on interpolation algorithms unable to learn from experience. In contrast, this paper proposes a…
Adapting to Dynamic LEO-B5G Systems : Meta-Critic Learning Based Efficient Resource Scheduling
2022
Low earth orbit (LEO) satellite-assisted communications have been considered as one of key elements in beyond 5G systems to provide wide coverage and cost-efficient data services. Such dynamic space-terrestrial topologies impose exponential increase in the degrees of freedom in network management. In this paper, we address two practical issues for an over-loaded LEO-terrestrial system. The first challenge is how to efficiently schedule resources to serve the massive number of connected users, such that more data and users can be delivered/served. The second challenge is how to make the algorithmic solution more resilient in adapting to dynamic wireless environments.To address them, we first…
Network-Assisted Resource Allocation with Quality and Conflict Constraints for V2V Communications
2018
The 3rd Generation Partnership Project (3GPP) has recently established in Rel. 14 a network-assisted resource allocation scheme for vehicular broadcast communications. Such novel paradigm is known as vehicle--to--vehicle (V2V) \textit{mode-3} and consists in eNodeBs engaging only in the distribution of sidelink subchannels among vehicles in coverage. Thereupon, without further intervention of the former, vehicles will broadcast their respective signals directly to their counterparts. Because the allotment of subchannels takes place intermittently to reduce signaling, it must primarily be conflict-free in order not to jeopardize the reception of signals. We have identified four pivotal types…
Data-Driven Spectrum Cartography via Deep Completion Autoencoders
2019
Spectrum maps, which provide RF spectrum metrics such as power spectral density for every location in a geographic area, find numerous applications in wireless communications such as interference control, spectrum management, resource allocation, and network planning to name a few. Spectrum cartography techniques construct these maps from a collection of measurements collected by spatially distributed sensors. Due to the nature of the propagation of electromagnetic waves, spectrum maps are complicated functions of the spatial coordinates. For this reason, model-free approaches have been preferred. However, all existing schemes rely on some interpolation algorithm unable to learn from data. …
On the Fidelity of IEEE 802.11 commercial cards
2006
The IEEE 802.11 D CF protocol is known to be fair in terms of long-term resource repartition among the contending stations. However, when considering real scenarios, where commercial 802.11 cards interact, very unpredictable as well as sometimes surprising behaviors emerge. Motivation of this paper is to investigate the reasons of the very evident disagreement between the theoretical IEEE 802.11 DCF protocol models and its practical implementations. Inparticular, we try to characterize the card behavior not only in terms of perceived throughput, but also in terms of low-level channel access operations. In fact, the simple throughput analysis does not allow to identify what affecting paramet…
Co-digestion of grass silage and cow manure in a CSTR by re-circulation of alkali treated solids of the digestate.
2008
Three laboratory, continuously stirred tank reactors (CSTRs) co-digesting grass silage and cow manure (forming 30% and 70% of substrate volatile solids (VS), respectively) were operated to evaluate the effects of re-circulating an alkali-treated and untreated solid fraction of the digestate back to the reactors. The CSTRs were operated at an organic loading rate (OLR) of 2 kg VS m(-3) day(-1) and hydraulic retention time (HRT) of 20 days with a semi-continuous mode of feeding. The feasibility of co-digestion with substrate VS containing 30% VS of crop was reinforced, resulting in average specific methane yield of about 180-185 1 CH4 kg(-1) VS. Re-circulation of the solid fraction of digesta…
Meaningful learning in business through serious games
2017
Purpose: The requirements of a business executive include the talent and creativity to solve problems and adapt to continuous changes presented by the economic and social environment. However, the university does not often prepare students in these skills. Businesses simulations are didactic tools in which participants assume a role and make decisions which affect the results of the company. This paper aims to provide empirical evidence on the effectiveness of business simulations in university teaching. Design/methodology: We have implemented business simulations in a course in the College of Economics at the University of Valencia, during the 2015-2016 academic year. Questionnaires were u…
Los archivos de distrito en Portugal: memoria administrativa, histórica y social
2018
Se presenta un análisis de la evolución histórico-jurídi ca de los Archivos de Distrito (AD) portugueses, como instituciones que asumen la salvaguarda del patrimo nio público-administrativo del país. Para ello se revisa la bibliografía más relevante sobre el tema, así como la documentación histórica, legal y política, describien do su historia desde sus orígenes y los nuevos caminos que se van trazando, en relación con el aumento de la accesibilidad a la documentación que gestionan y a las nuevas estrategias de difusión de la información entre la ciudadanía. Todo ello en el marco de las distintas ini ciativas de modernización administrativa y las nuevas tecnologías disponibles.
