Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor
2010
Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …
Univariate and multivariate properties of wind velocity time series
2009
We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.
Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …
The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …
2021
The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…
Precision Agriculture: Past, Present and Future
2011
From 1978 the Global Positioning System, needed for sensing the position of military targets (e.g. buildings, machinery), was developed as a pure military system, while in 1983 it was made available also for public use. Therefore, at the beginning of 80s precision agriculture, requiring GPS for sensing the position to which any measured field parameter must be geo-referenced, was implemented for the first time in US. In fact, soil and crop parameters are spatially variable in a field, so that spatially uniform rate crop input applications cause increased environmental impact and crop input waste. In order to reduce the environmental impact and optimise the use of crop inputs, precision agri…
The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts
2017
In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…

Työkykyyn vaikuttavat tekijät opettajien kokemina sekä vuosina 2012–2017 valmistuneiden opettajien kokemuk-sia työelämään siirtymisestä ja koulutuksista saaduista valmiuksista. Liikuntatieteellinen tiedekunta, Jyväskylän yliopisto, liikuntapedagogiikan pro gradu –tutkielma, 92 s, ja 11 liitettä. Tämän tutkimuksen tarkoituksena oli selvittää millaisiksi vuosina 2012¬–2017 valmistuneet liikunnan- ja terveystiedonopettajat kokevat koulutuksestaan saamansa valmiudet ja miten ne vastaavat työssä tarvittuja taitoja sekä miten odotukset työstä olivat kohdanneet todellisuutta siirryttäessä työelämään. …
Reciprocal Relations between Work-Related Authenticity and Intrinsic Motivation, Work Ability and Depressivity: A Two-Wave Study
2017
This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organization in the social sector were analyzed using multilevel structural equation modeling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1. …
Work ability as a determinant of old age disability severity: evidence from the 28-year Finnish Longitudinal Study on Municipal Employees
2012
Background and aims: Lower occupational class correlates with a higher disability risk later in life. However, it is not clear whether the demands made by mental and physical work relative to individual resources in midlife predict well-being in old age. This study investigated prospectively whether work ability in midlife predicts disability severity in activities of everyday living in old age. Methods: Data come from the population-based 28-year follow-up called Finnish Longitudinal Study of Municipal Employees. A total of 2879 occupationally active persons aged 44-58 years answered a questionnaire on work ability at baseline in 1981 and activities of daily living in 2009. At baseline, pe…
Effects of rehabilitative psychotherapy on labour market success: Evaluation of a nationwide programme
2022
Aims: Psychotherapy is a widely used treatment for mental disorders, but whether it also improves employment and other labour market outcomes remains inconclusive. This study examined the effectiveness of a nationwide subsidized psychotherapy programme using extensive register-based data. Methods: The sample consisted of individuals who applied for rehabilitative psychotherapy in Finland in 2009–2012 ( n = 35,083). Prior to 2011, some applications were rejected due to the limited budget that the central government provided for the programme. From 2011, all eligible applicants were granted rehabilitation. We used propensity score matching to create balanced samples of those who received a ne…
