Muon-capture strength functions in intermediate nuclei of 0νββ decays
2019
Capture rates of ordinary muon capture (OMC) to the intermediate nuclei of neutrinoless double beta (0νββ) decays of current experimental interest are computed. The corresponding OMC (capture-rate) strength functions have been analyzed in terms of multipole decompositions. The computed low-energy OMC-rate distribution to 76 As is compared with the available data of Zinatulina et al. [Phys. Rev. C 99, 024327 (2019)]. The present OMC computations are performed using the Morita-Fujii formalism by extending the original formalism beyond the leading order. The participant nuclear wave functions are obtained in extended no-core single-particle model spaces using the spherical version of proton-ne…

Nuorten salibandypelaajien nuuskan käyttö ja siihen yhteydessä olevat tekijät
2017
Suomalaisten nuorten tupakointi on vähentynyt, kun taas nuuskakokeilut ja nuuskan käyttö ovat lisääntyneet. Aiempien tutkimusten mukaan nuuskan käyttö on yleistä myös urheilijoiden keskuudessa. Tässä tutkimuksessa tarkasteltiin nuorten salibandypelaajien nuuskakokeiluja ja nuuskan käyttöä sekä siihen yhteydessä olevia tekijöitä. Tutkimusaineisto kerättiin sähköisellä kyselylomakkeella joulukuun 2016 ja tammikuun 2017 välisellä ajalla. Kyselyyn vastasi 449 pelaajaa (poikia 302, tyttöjä 147, keski-ikä 16,7 vuotta). Aineiston analysoinnissa hyödynnettiin ristiintaulukointeja ja khiin neliö-testiä sekä logistista regressioanalyysia. Salibandya pelaavista 13–20-vuotiaista nuorista 39 prosenttia …
Convergence Analysis of Extended Kalman Filter for Sensorless Control of Induction Motor
2015
This paper deals with convergence analysis of the extended Kalman filters (EKFs) for sensorless motion control systems with induction motor (IM). An EKF is tuned according to a six-order discrete-time model of the IM, affected by system and measurement noises, obtained by applying a first-order Euler discretization to a six-order continuous-time model. Some properties of the discrete-time model have been explored. Among these properties, the observability property is relevant, which leads to conditions that can be directly linked with the working conditions of the machine. Starting from these properties, the convergence of the stochastic state estimation process, in mean square sense, has b…

wytwarzania energii elektrycznej z substancji odpadowych, jak i technologii oczyszczania ścieków. Ogniwa te charakteryzują się niskimi kosztami inwestycyjnymi. Ze względu na znakomite własności katalityczne, w wysokowydajnych ogniwach paliwowych (np. wodorowo-tlenowych), jako katalizator stosowana jest platyna. Jednak koszt platyny praktycznie uniemożliwia stosowanie jej w MFC. Z tego względu należy poszukiwać innych katalizatorów nie zawierających metali szlachetnych. W mikrobiologicznych ogniwach paliwowych najczęściej stosuje się elektrody grafitowe. Praca przedstawia analizę możliwości wykorzystania stali nierdzewnej oraz stopu Cu-B jako katalizatora elektrody paliwowej w mikrobiologicz…

Virtual Slovak : insight into learning Slovak in an e-learning environment
2015
This paper offers insight into learning Slovak in an e-learning environment. The need to reach distance-learners of Slovak led to the implementation of a web-based course on Slovak language and culture in 2008–2010. The pedagogical basis of the course, called Virtual Slovak, is the socioconstructivist approach to teaching and learning, in which the focus is on the development of learners’ communicative competence. This teaching experiment led to a study in which the focus was on learners’ beliefs and experiences regarding learning Slovak in an e-learning environment. The results showed that this particular learning environment had a positive impact on the development of learners’ agency. Th…
FREE SPACE OPTICS LINKS AFFECTED BY OPTICAL TURBULENCE: CHANNEL MODELING, MEASUREMENTS AND CODING TECHNIQUES FOR ERROR MITIGATION
2014
FSO is an optical wireless line-of-sight communication system able to offer good broadband performance, electromagnetic interference immunity, high security, license-free operation, low power consumption, ease of relocation, and straightforward installation. It represents a modern technology, significantly functional when it is impossible, expensive or complex to use physical connections or radio links. Unfortunately, since the transmission medium in a terrestrial FSO link is the air, these communications are strongly dependent on various atmospheric phenomena (e.g., rain, snow, optical turbulence and, especially, fog) that can cause losses and fading. Therefore, in worst-case conditions, i…
Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
2020
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
