Methods for estimating forest stem volumes by tree species using digital surface model and CIR images taken from light UAS
2012
In this paper we consider methods for estimating forest tree stem volumes by species using images taken from light unmanned aircraft systems (UAS). Instead of using LiDAR and additional multiband imagery a color infrared camera mounted to a light UAS is used to acquire both imagery and the DSM of target area. The goal of this study is to accurately estimate tree stem volumes in three classes. The status of the ongoing work is described and an initial method for delineating and classifying treetops is presented.
Detecting explosive substances by the IR spectrography
2014
Fast and safe detection methods of explosive substances are needed both before and after actualized explosions. This article presents an experiment of the detection of three selected explosives by the ATR FTIR spectrometer and by three different IR hyperspectral imaging devices. The IR spectrometers give accurate analyzing results, whereas hyperspectral imagers can detect and analyze desired samples without touching the unidentified target at all. In the controlled explosion experiment TNT, dynamite and PENO were at first analyzed as pure substances with the ATR FTIR spectrometer and with VNIR, SWIR and MWIR cameras. After three controlled explosions also the residues of TNT, dynamite and P…
The challenges of analysing blood stains with hyperspectral imaging
2014
Hyperspectral imaging is a potential noninvasive technology for detecting, separating and identifying various substances. In the forensic and military medicine and other CBRNE related use it could be a potential method for analyzing blood and for scanning other human based fluids. For example, it would be valuable to easily detect whether some traces of blood are from one or more persons or if there are some irrelevant substances or anomalies in the blood. This article represents an experiment of separating four persons' blood stains on a white cotton fabric with a SWIR hyperspectral camera and FT-NIR spectrometer. Each tested sample includes standardized 75 _l of 100 % blood. The results s…
Democracy, poverty and civil society in Mozambique
2015
National elections were held in Mozambique for the fifth time in October 2014. As a state, Mozambique – like many ‘fourth-wave’ transition countries – fulfils the formal criteria of democracy. But to what extent are the mechanisms of accountability implemented? In Africa, two issues have been identified as key impediments for successful democratic transition: failure to improve the welfare of the poor and the ‘pre-modern’ character of civil society. In Mozambique, robust economic growth has been accompanied by growing inequality, while traditional civil society organisations (CSOs) have become increasingly visible on local level since the political transition in 1994. Based on the analysis …
Device-based physical activity levels among Finnish adolescents with functional limitations
2019
Background Monitoring physical activity among young adolescents with disabilities is a top academic priority. People with disabilities are a diverse group with various abilities in different human functioning. Therefore, we used a novel approach through functional limitations as a marker for disabilities and examined physical activity levels. Objective To investigate the levels and differences in light (LPA) and moderate-to-vigorous (MVPA) intensity physical activity between young adolescents with and without functional limitations. Methods The study included young adolescents (n = 1436) aged 11–15 years olds who attended general schools that were part of the 2016 Finnish School-aged Physic…
Child socioemotional behavior and adult temperament as predictors of physical activity and sedentary behavior in late adulthood
2023
Background Most studies investigating the association of temperament with physical activity and sedentary behavior have examined children or adolescents, employed cross-sectional or longitudinal designs that do not extend from childhood into adulthood, and utilized self- or parent-reported data on physical activity and sedentary behavior. This longitudinal study investigated whether socioemotional behavior in childhood and temperament in middle adulthood predict accelerometer-measured physical activity and sedentary behavior in late adulthood. Methods This study was based on the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). Socioemotional behavior (behavioral ac…
INDAGINE SULL’ IDROREPELLENZA DEL SUOLO DI UNA PINETA ARTIFICIALE MEDITERRANEA
2016
Nell’indagine è stata caratterizzata l’idrorepellenza del suolo di una pineta artificiale Mediterranea utilizzando sia il tradizionale Water Drop Penetration Time (WDPT) test che due indici desunti da esperimenti di infiltrazione condotti con il MiniDisk Infiltrometer (MDI). In particolare, il Repellency Index (RI) è stato calcolato come rapporto tra i valori di sorptività misurati con etanolo e acqua, mentre il Water Repellency Cessation Time (WRCT) è stato ricavato utilizzando l’informazione acquisita nella fase idrofobica e in quella idrofila del processo di infiltrazione con acqua. Tutti gli indici hanno inequivocabilmente indicato che la lettiera di Pinus pinaster è altamente idrofobic…
