Tectonometamorphic evolution of high-pressure rocks from the island of Amorgos (Central Aegean, Greece)
2007
Structural and metamorphic data from the island of Amorgos (central Aegean Sea) show evidence for the existence of two distinct high-pressure units, the Metabasite Unit and the Basal Conglomerate Unit. These are exposed at the base of a thick marble sequence and overlying flysch deposits. The Metabasite Unit is characterized by a mineral assemblage of blue amphibole, garnet and clinopyroxene, indicating P – T conditions of 500–600 °C and >13 kbar. It is juxtaposed below carpholite-bearing metaconglomerates and quartz-rich micaschists of the Basal Conglomerate Unit, for which metamorphic conditions of 300–450 °C and 10–14 kbar are estimated. The contact between the two units is interpreted a…
The assessment of detachment among university students: Validation of the Recovery Experience Questionnaire in educational contexts
2017
El objetivo de este estudio fue adaptar y validar el Cuestionario de Experiencias de Recuperación (Recovery Experience Questionnaire) para su uso en un contexto educativo. Hasta el momento, la evaluación del detach- ment o distanciamiento psicológico ha sido utilizada fundamentalmente en contextos laborales. El estudio tuvo como objetivo verificar la validez fac- torial y la validez de criterio, a través de la correlación con variables como la autorregulación, el compromiso (engagement), las estrategias de afrontamien- to, y las dimensiones de la personalidad contempladas en el modelo de los cinco grandes factores (Big Five Model) en una muestra de 468 estudiantes universitarios españoles. …
Modeling and Simulation of Network-on-Chip Systems with DEVS and DEUS
2013
Networks on-chip (NoCs) provide enhanced performance, scalability, modularity, and design productivity as compared with previous communication architectures for VLSI systems on-chip (SoCs), such as buses and dedicated signal wires. Since the NoC design space is very large and high dimensional, evaluation methodologies rely heavily on analytical modeling and simulation. Unfortunately, there is no standard modeling framework. In this paper we illustrate how to design and evaluate NoCs by integrating the Discrete Event System Specification (DEVS) modeling framework and the simulation environment called DEUS. The advantage of such an approach is that both DEVS and DEUS support modularity—the fo…
Levy targeting and the principle of detailed balance
2011
We investigate confining mechanisms for Lévy flights under premises of the principle of detailed balance. In this case, the master equation of the jump-type process admits a transformation to the Lévy-Schrödinger semigroup dynamics akin to a mapping of the Fokker-Planck equation into the generalized diffusion equation. This sets a correspondence between above two stochastic dynamical systems, within which we address a (stochastic) targeting problem for an arbitrary stability index μ ε (0,2) of symmetric Lévy drivers. Namely, given a probability density function, specify the semigroup potential, and thence the jump-type dynamics for which this PDF is actually a long-time asymptotic (target) …
Results of a literature review on methods for estimating buildings energy demand at district level
2019
Abstract In the framework of distributed energy planning, evaluating reliable energy profiles of different sectors has a prominent role. At the same time, it is a quite challenging task, since the availability of actual energy profiles of buildings at the district level is not widespread. A survey of over 70 studies in scientific literature has been accomplished and a set of criteria has been defined for classifying the selected contributions based on the energy demand data features, source and/or estimation methods, highlighting the ones adopting hourly energy profiles. As final results, tables summarizing the main methods characteristics and a selection of studies providing directly useab…

Ocular manifestations are rare in this infection. We describe the case of a man complaining of an intense retro-orbital headache, fever, arthralgia, and bilateral loss of vision, who showed an anterior uveitis accompanied by exudative bilateral inferior retinal detachment and optic disk edema. At the beginning, a Vogt–Koyanag…
Quality evaluation of grapes for mechanical harvest using vis NIR spectroscopy
2019
Mechanical harvest of grapes is one of the operations that mostly influence the quality of the future wine. The shaking frequency of the harvesting machine is usually adjusted on the basis of the grape berry characteristics in order to limit grape juice production that is a potential cause of uncontrolled fermentations. These evaluations usually require time, personnel and laboratory analyses. The introduction of a vis NIR system to rapidly and reliably evaluate the berry properties in field before mechanical harvest could be a good alternative. The aim of this study was to evaluate the feasibility of applying vis NIR spectroscopy as a non-destructive technique on grapes cv. Syrah and Chard…
Green LAI Mapping and Cloud Gap-Filling Using Gaussian Process Regression in Google Earth Engine
2021
For the last decade, Gaussian process regression (GPR) proved to be a competitive machine learning regression algorithm for Earth observation applications, with attractive unique properties such as band relevance ranking and uncertainty estimates. More recently, GPR also proved to be a proficient time series processor to fill up gaps in optical imagery, typically due to cloud cover. This makes GPR perfectly suited for large-scale spatiotemporal processing of satellite imageries into cloud-free products of biophysical variables. With the advent of the Google Earth Engine (GEE) cloud platform, new opportunities emerged to process local-to-planetary scale satellite data using advanced machine …
Pašnodarbināto menedžments
2021
Esošie pētījumi par jauno paaudžu īpašo motivāciju nosacītas nodarbinātības apstākļos ir visai ierobežoti. Tāpēc ir vajadzīga turpmāka izpēte, lai izvērtētu iemeslus viņu gatavībai pievienoties pastāvīgai nodarbinātībai, kā arī īpašos instrumentus viņu motivēšanai. Esošā zinātniskā literatūra, statistiski un primāri dati tika apkopoti un analizēti, lai izpētītu specifiskus faktorus, kas varētu ietekmēt jauniešu motivāciju nosacītājos amatos. Tādējādi, jauniešu nodrošināšana ar pietiekamu atalgojuma līmeni ir izrādījusies visefektīvākais motivācijas instruments, ko uzņēmumi varētu izmantot jaunu nosacītu darbinieku motivēšanai.
Exploring the future: Runtime scenario selection for complex and time-bound decisions
2015
Abstract Scenarios are designed to support decision-makers in gaining a better understanding of the consequences of decisions. Despite their popularity in IT for Foresight, a major obstacle is the complexity of strategic decisions and the resulting multitude of scenarios. Therefore choices need to be made, which scenarios to fully work out, by which experts and in which level of detail. This paper presents an approach to support making these trade-offs between accuracy and resources spent by prioritising scenarios based on their significance for the decision even on the basis of incomplete information. This approach combines theoretical findings in decision theory with results that were eli…
