Estimates of the organic aerosol volatility in a boreal forest using two independent methods
(Copernicus Publications on behalf of the European Geosciences Union, 2017)The volatility distribution of secondary organic aerosols that formed and had undergone aging – i.e., the particle mass fractions of semi-volatile, low-volatility and extremely low volatility organic compounds in the ...info:eu-repo/semantics/article

Estimating absorption and scattering in quantitative photoacoustic tomography with an adaptive Monte Carlo method for light transport
(American Institute of Mathematical Sciences, 2024)In this work, the optical inverse problem of quantitative photoacoustic tomography is studied. Maximum a posteriori estimates for absorption and scattering are computed from absorbed energy density, and the reliability of ...

Estimating daytime sleepiness with previous night EEG, EOG and EMG spectrograms in patients with suspected sleep apnea using a convolutional neural network
(Oxford University Press (OUP), 2020)A common symptom of obstructive sleep apnea (OSA) is excessive daytime sleepiness (EDS). The gold standard test for EDS is the multiple sleep latency test (MSLT). However, due to its high cost, MSLT is not routinely conducted ...Tieteelliset aikakauslehtiartikkelit

Estimating forest stand density and structure using Bayesian individual tree detection, stochastic geometry, and distribution matching
(Elsevier BV, 2019)Errors in individual tree detection and delineation affect diameter distribution predictions based on crown attributes extracted from the detected trees. We develop a methodology for circumventing these problems. The method ...Tieteelliset aikakauslehtiartikkelit

Estimating Mechanical Properties of Bovine Knee Ligaments and Tendons with Near Infrared Spectroscopy
(The Optical Society, 2018)In this study, mechanical properties of bovine knee ligament and tendon samples were estimated using near infrared spectroscopy (NIRS). Properties related to sample stress-relaxation characteristics were found to be suitable ...other

Estimating production in ducks : a comparison between ground surveys and unmanned aircraft surveys
(Springer Nature America, Inc, 2018)We tested the use of unmanned aerial systems (UAS) in duck brood surveys in boreal wetlands in Finland. We performed brood surveys at the same wetlands concurrently with ground-based point counts and using a UAS (multicopter; ...Tieteelliset aikakauslehtiartikkelit

Estimation of atmospheric particle formation rates through an analytical formula: validation and application in Hyytiälä and Puijo, Finland
(Copernicus Publications on behalf of the European Geosciences Union, 2017)The formation rates of 3 nm particles were estimated at SMEAR IV, Puijo (Finland), where the continuous measurements extend only down to 7 nm in diameter. We extrapolated the formation rates at 7 nm (J7) down to 3 nm (J3) ...info:eu-repo/semantics/article

Estimation of the high-spatial-resolution variability in extreme wind speeds for forestry applications
(Copernicus GmbH, 2017)The bioeconomy has an increasing role to play in climate change mitigation and the sustainable development of national economies. In Finland, a forested country, over 50 % of the current bioeconomy relies on the sustainable ...info:eu-repo/semantics/article

EURODELTA III exercise: An evaluation of air quality models' capacity to reproduce the carbonaceous aerosols
(Elsevier BV, 2019)The carbonaceous aerosol accounts for an important part of total aerosol mass, affects human health and climate through its effects on physical and chemical properties of the aerosol, yet the understanding of its atmospheric ...Tieteelliset aikakauslehtiartikkelit
