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…
Hyperspectral imaging based biomass and nitrogen content estimations from light-weight UAV
2013
Hyperspectral imaging based precise fertilization is challenge in the northern Europe, because of the cloud conditions. In this paper we will introduce schemes for the biomass and nitrogen content estimations from hyperspectral images. In this research we used the Fabry-Perot interferometer based hypespectral imager that enables hyperspectral imaging from lightweight UAVs. During the summers 2011 and 2012 imaging and flight campaigns were carried out on the Finnish test field. Estimation mehtod uses features from linear and non-linear unmixing and vegetation indices. The results showed that the concept of small hyperspectral imager, UAV and data analysis is ready to operational use.
Coupling high-resolution satellite imagery with ALS-based canopy height model and digital elevation model in object-based boreal forest habitat type …
2014
We developed a classification workflow for boreal forest habitat type mapping. In object-based image analysis framework, Fractal Net Evolution Approach segmentation was combined with random forest classification. High-resolution WorldView-2 imagery was coupled with ALS based canopy height model and digital terrain model. We calculated several features (e.g. spectral, textural and topographic) per image object from the used datasets. We tested different feature set alternatives; a classification accuracy of 78.0 % was obtained when all features were used. The highest classification accuracy (79.1 %) was obtained when the amount of features was reduced from the initial 328 to the 100 most imp…
Hemotransfūzija un taisnās zarnas vēža ķirurģija
2017
Tēmas nosaukums: Hemotransfūzija un taisnās zarnas vēža ķirurģija. Ievads: Taisnās zarnas vēzis daudzus gadus joprojām ir sarežģīta ķirurģiska problēma. Dzīvildzes rādītāju uzlabošanās vērojama 20 gs. deviņdesmitajos gados, lielā mērā pateicoties uzlabotai vietējai kontrolei ieviešot totālu mezorektālu ekscīziju, kā labāko aprūpes praksi un neodajuvantas radioterapijas izmantošanai. Dažos gadījumos pacientiem ar taisnās zarnas vēzi ir nepieciešama asins pārliešana. Bez neliela riska asins pārliešanas laikā pārnest vīrusa infekciju, pastāv citi daži faktori kuri var ietekmēt pacienta veselību un turpmāko dzīvildzi. Viens no šiem pētāmajiem faktoriem ir hemotransfūzijas negatīvā ietekme uz re…
Exploring relations between Big Five personality traits and musical emotions embodied in spontaneous dance
2022
We explored the hypothesis that musical emotions are embodied differentially by people according to their personality. Nine hundred and fifty two individuals completed the Big Five personality inventory. A subset of 60 participants were asked to spontaneously move to 30 short musical stimuli while being recorded with a motion-capture system. The musical stimuli were separately rated for perceived emotions. Embodied musical emotions were evaluated as the correlation between features derived from the motion-capture data and the mean ratings of perceived emotions. Correlations between embodied musical emotions and personality traits provided tentative support for our hypothesis. A series of l…
The Connection of Machiavellianism, Self-control and Induced Emotions with Solving Tasks
2014
The presented research shows that there is a connection between Machiavellianism and the way of solving problem tasks in the situations of inducing chosen emotions. The results obtained in this research show that Machiavellians are characterised by the self-control of the stop type and that the induction of emotions has not such a connection with solving tasks by them as it is in case of people with a low level of Machiavellianism. Moreover, it has been shown that people with high Machiavellianism do not trust other people and are focused on the maximization of profit.
Kun perusopetuksen oppilaat oireilevat psyykkisesti : opettajien kokemuksia
2017
The aim of this study was to examine and interpret teachers’ experiences of pupils with emotional and behavioural disordres in comprehensive schools in Finland. The term ‘pupils with emotional and behavioural disorders’ refers here to children who either cannot or do not want to act according to the general expectations in a school climate. Children live in several social settings that affect their development, of which the most important ones are home and the school. It is known that positive teacher-pupil interaction has an advantageous effect on student adaptation, performance and behavior. However, behavior-related problematics affect the forming of interactive relationships. Educationa…
From social and emotional learning in adolescence to emotional-skill training in teachers = Desde la educación socio-emocional en adolescencia al en…
2019
The idea of introducing social and emotional learning in educational settings is based on the assumption that emotions are an essential element of school life. Emotional competencies are conducive to student learning and well-being, in addition to conveying emotional resources for teachers and educators. The development of such abilities is a prerequisite for students and teachers to engage in productive and enjoyable classroom dynamics. Indeed, well-developed emotional competence enhances students’ psychological adjustment, self-esteem, adaptive coping with stress at school and academic success. However, engaging in disruptive behaviors and school violence (bullying) may be attributed to a…
The effect of perceived school climate and teacher efficacy in behavior management on job satisfaction and burnout: A longitudinal study
2016
Abstract This study investigated how perceived school climate affects teachers' job satisfaction and burnout and how self-efficacy and collective efficacy in behavior management mediate the effect of perceived school climate on job satisfaction and burnout. The questions were answered using longitudinal questionnaire data collected from 642 Finnish lower secondary school teachers. A structural equation model revealed that school climate had a positive effect, partly mediated by self-efficacy, on job satisfaction. Collective efficacy in student discipline did not explain either job satisfaction or burnout. Self-efficacy in managing behavior had a positive effect on job satisfaction and a neg…
