Simple flume with a central baffle
2016
Abstract In this paper the stage-discharge relationship of a flume with a central baffle is theoretically deduced using the Buckingham-Theorem of the dimensional analysis and the self-similarity theory. The new stage-discharge equation is calibrated by the measurements carried out by Peruginelli and Bonacci using a baffle having a given throat length and five different values of the contraction ratio. Finally, for a given throat length, a relationship linking the discharge with the upstream water depth, the contraction ratio and the contracted width is deduced.
Palvelusta hyödykkeeksi : taiteen käsitteen merkityksen kehittyminen taide- ja kulttuuripoliittisissa selonteoissa 1978-2010
2014
Tutkimuksen lähtökohtana ja aineistona ovat vuosien 1978-2010 välillä hallituksen eduskunnalle antamat neljä taide- ja kulttuuripoliittista selontekoa. Tutkimuksessa tarkastellaan taiteen käsitteen kehittymistä edellä mainituissa poliittisissa asiakirjoissa. Keskeisiä tutkimuskysymyksiä ovat: Mitä ja miten taide on taide- ja kulttuuripoliittisissa selonteoissa 1978–2010? Miten taide käsitteenä on muuttunut selonteoissa ja mitkä tekijät ovat sitä muuttaneet? Keitä selontekojen valmistelutyössä on ollut mukana ja millaisia asiantuntijoita työn eri vaiheissa on kuultu? Työ on toteutettu aineistolähtöisesti diskurssianalyysinä. Tutkimuksen taustoittavissa luvuissa käsitellään tutkimuksen keskei…
Review article: recommended reading list of early publications on atomic layer deposition - outcome of the "virtual Project on the History of ALD"
2017
Atomic layer deposition (ALD), a gas-phase thin film deposition technique based on repeated, self-terminating gas-solid reactions, has become the method of choice in semiconductor manufacturing and many other technological areas for depositing thin conformal inorganic material layers for various applications. ALD has been discovered and developed independently, at least twice, under different names: atomic layer epitaxy (ALE) and molecular layering. ALE, dating back to 1974 in Finland, has been commonly known as the origin of ALD, while work done since the 1960s in the Soviet Union under the name "molecular layering" (and sometimes other names) has remained much less known. The virtual proj…

Reflectance Measurement Method Based on Sensor Fusion of Frame-Based Hyperspectral Imager and Time-of-Flight Depth Camera
2022
Hyperspectral imaging and distance data have previously been used in aerial, forestry, agricultural, and medical imaging applications. Extracting meaningful information from a combination of different imaging modalities is difficult, as the image sensor fusion requires knowing the optical properties of the sensors, selecting the right optics and finding the sensors’ mutual reference frame through calibration. In this research we demonstrate a method for fusing data from Fabry–Perot interferometer hyperspectral camera and a Kinect V2 time-of-flight depth sensing camera. We created an experimental application to demonstrate utilizing the depth augmented hyperspectral data to measu…
Sex-specific signatures of intrinsic hippocampal networks and regional integrity underlying cognitive status in multiple sclerosis
2021
Abstract The hippocampus is an anatomically compartmentalized structure embedded in highly wired networks that are essential for cognitive functions. The hippocampal vulnerability has been postulated in acute and chronic neuroinflammation in multiple sclerosis, while the patterns of occurring inflammation, neurodegeneration or compensation have not yet been described. Besides focal damage to hippocampal tissue, network disruption is an important contributor to cognitive decline in multiple sclerosis patients. We postulate sex-specific trajectories in hippocampal network reorganization and regional integrity and address their relationship to markers of neuroinflammation, cognitive/memory per…
Effect of the Si doping on the properties of AZO/SiC/Si heterojunctions grown by low temperature pulsed laser deposition
2020
Abstract The structural and photoelectrical properties of Al-doped ZnO (AZO)/SiC/p-Si and AZO/SiC/n-Si heterojunctions, fabricated at low temperature by pulsed laser deposition, were investigated by means of a number of techniques. Raman analysis indicates that SiC layers have the cubic 3C-SiC phase, whilst X-ray diffraction measurements show that AZO films exhibit a hexagonal wurtzite structure, highly textured along the c-axis, with average crystallites size of 35.1 nm and lattice parameter c of 0.518 nm. The homogeneous and dense surface morphology observed by scanning electron microscopy was confirmed by atomic force microscopy images. Moreover, UV–Vis-NIR spectra indicated a high trans…
Localized surface plasmon resonance in silver nanoparticles: Atomistic first-principles time-dependent density-functional theory calculations
2015
We observe using ab initio methods that localized surface plasmon resonances in icosahedral silver nanoparticles enter the asymptotic region already between diameters of 1 and 2 nm, converging close to the classical quasistatic limit around 3.4 eV. We base the observation on time-dependent density-functional theory simulations of the icosahedral silver clusters Ag$_{55}$ (1.06 nm), Ag$_{147}$ (1.60 nm), Ag$_{309}$ (2.14 nm), and Ag$_{561}$ (2.68 nm). The simulation method combines the adiabatic GLLB-SC exchange-correlation functional with real time propagation in an atomic orbital basis set using the projector-augmented wave method. The method has been implemented for the electron structure…
Depresijas simptomu novērtējums klīniskā un neklīniskā izlasē
2021
Šī pētījuma mērķis ir noskaidrot, kādi ir depresijas simptomu profili mērījumos starp klīnisko un neklīnisko (vispārējo) izlasi. Pētījuma galvenais jautājums bija, kādi būs indivīdiem novērojami depresijas simptomu profili jeb kāda būs depresijas simptomu heterogenitāte? Pētījumā piedalījās 292 respondenti. Pētījuma dalībnieki bija vecumā no 14 līdz 53 gadiem (M = 34,27; SD = 11,12; sievietes 75,3%; vīrieši 24,7%). Pētījuma ietvaros tika izveidotas divas izlases – neklīniskā jeb vispārējā izlase un klīniskā izlase. Vispārējo izlasi veidoja 262 respondenti, savukārt klīnisko izlasi veidoja 30 respondenti.
