Enhancing Digital Skills of Early Childhood Teachers Through Online Science, Technology, Engineering, Art, Math Training Programs in Estonia

2022

Teacher professional development programs, including mid- and long-term Science, Technology, Engineering, Art, Math (STEAM) courses, have recently moved from in person learning at university premises to an online environment. Whether it is a temporary change in learning methods caused by the COVID-19 restrictions or whether it will become a new normal is currently under discussion in many teacher training institutions around the world. The aim of this study was to design and implement time- and money-saving synchronous online teacher training format for conducting co-design courses for early childhood teachers in the theme of STEAM integrated learning activities. Based on Tallinn University…

Sulfonēta poliēterēterketona elektrisko īpašību pētīšana ar plūsmas potenciāla mērījumiem

2022

Darba ietvaros ir izgatavotas sulfonētas poliēterēteraketona membrānas ar dažādām sulfonēšanas pakāpēm. Patieso sulfonēšanas pakāpi ieguva, izmantojot titrēšanas metodi. Virsmas dzeta potenciāla noteikšanai izmantoja plūsmas potenciāla mērījumus. Izmantojot SurPASS™ 3 instrumentu, dzeta potenciālu aprēķināja no eksperimentu laikā izmērītajām spiediena un plūsmas potenciāla izmaiņām.

Improvement of BEST (Beerkan Estimation of Soil Transfer parameters) method for soil hydraulic characterization

Interpreting and modeling soil hydrological processes require the determination of the soil hydraulic characteristic curves, i.e. the relationships between volumetric soil water content, pressure head, and hydraulic conductivity. Using traditional methods to determine these properties is expensive and time consuming. Haverkamp et al. (1996) pioneered a specific method for soil hydraulic characterization known as the “Beerkan method”. An improved version of this methodology, called the Beerkan Estimation of Soil Transfer parameters (BEST) procedure, was developed by Lassabatère et al. (2006) to simplify soil hydraulic characterization. BEST considers certain analytic formulae for hydraulic c…

Optimal Buffer Resource Allocation in Wireless Caching Networks

2019

Wireless caching systems have been exhaustively investigated in recent years. Due to limited buffer capacity, and unbalanced arrival and service rates, the backlogs may exist in the caching node and even cause buffer overflow. In this paper, we first investigate the relationship among backlogs, buffer capacity, data arrival rate and service rate, utilizing the martingale theory which is flexible in handling any arrival and service processes. Then given a target buffer overflow probability, the minimal required buffer portion is determined. If the devoted buffer capacity can fulfill all serving users' minimal buffer requirements, an optimization problem is constructed with the objective to m…

A method for skin malformation classification by combining multispectral and skin autofluorescence imaging

2018

As the incidence of skin cancer is still increasing worldwide, there is a high demand for early, non-invasive and inexpensive skin lesion diagnostics. In this article we describe and combine two skin imaging methods: skin autofluorescence (AF) and multispectral criterion p’. To develop this method, we used custom made prototype with 405 nm, 526 nm, 663 nm and 964 nm LED illuminations, perpendicular positioned linear polarizers, 515 nm filter and IDS camera. Our aim is to develop a skin lesion diagnostic device for primary care physicians who do not have experience in dermatology or skin oncology. In this study we included such common benign lesion groups as seborrheic keratosis, hyperkerato…

Tra decorazione e grafica. Il corpus di Ugo Zovetti nel Gabinetto dei Disegni e delle Stampe della Fondazione Giorgio Cini

2020

Il contributo è dedicato a Ugo Zovetti (Curzola, 1879 - Milano, 1974), figura poliedrica di grande interesse che ha attraversato con originalità le arti del XX secolo distinguendosi tra i protagonisti della decorazione del libro come autore di pregevoli carte decorate. Ugo Zovetti fu un esponente della Secessione Viennese che ebbe larga parte nella diffusione del gusto secessionista e della Wiener Werkstätte in Italia, dove si affermò nel campo della decorazione durante gli anni dedicati all’insegnamento nella sede dell’ISIA di Monza. Nella prospettiva di una lettura della sua produzione tra grafica e decorazione, viene per la prima volta preso in esame e pubblicato l’inedito corpus di sue …

Mechanics and self-organization in tissue development

2021

Self-organization is an all-important feature of living systems that provides the means to achieve specialization and functionality at distinct spatio-temporal scales. Herein, we review this concept by addressing the packing organization of cells, the sorting/compartmentalization phenomenon of cell populations, and the propagation of organizing cues at the tissue level through traveling waves. We elaborate on how different theoretical models and tools from Topology, Physics, and Dynamical Systems have improved the understanding of self-organization by shedding light on the role played by mechanics as a driver of morphogenesis. Altogether, by providing a historical perspective, we show how i…

Neural Mechanisms Underlying Human Auditory Evoked Responses Revealed By Human Neocortical Neurosolver

2022

Funding Information: This study was supported by National Institutes of Health (Grant Nos. NIBIB RO1 EB022889, NIMH RO1 MH106174). Publisher Copyright: © 2021, The Author(s). Auditory evoked fields (AEFs) are commonly studied, yet their underlying neural mechanisms remain poorly understood. Here, we used the biophysical modelling software Human Neocortical Neurosolver (HNN) whose foundation is a canonical neocortical circuit model to interpret the cell and network mechanisms contributing to macroscale AEFs elicited by a simple tone, measured with magnetoencephalography. We found that AEFs can be reproduced by activating the neocortical circuit through a layer specific sequence of feedforwar…
