Identifying Past and Current Trends in Technology Education in Finland
2021
Technology education makes a unique contribution to the development of all young people by providing them a wide range of knowledge and skills. It has a role in shaping future debates and discourses by developing students’ technological literacy and by raising awareness of various dimensions of technology. In order to understand technology education in Finnish basic education, it is necessary to consider it within the subject of craft, particularly the domain of technical craft activities. However, the role of technology education has been and still is undefined in Finland. Thus, we need strategic planning and research in order to develop the necessary procedures and operations to achieve i…

Experimental generalized quantum suppression law in Sylvester interferometers
2017
Photonic interference is a key quantum resource for optical quantum computation, and in particular for so-called boson sampling machines. In interferometers with certain symmetries, genuine multiphoton quantum interference effectively suppresses certain sets of events, as in the original Hong-Ou-Mandel effect. Recently, it was shown that some classical and semi-classical models could be ruled out by identifying such suppressions in Fourier interferometers. Here we propose a suppression law suitable for random-input experiments in multimode Sylvester interferometers, and verify it experimentally using 4- and 8-mode integrated interferometers. The observed suppression is stronger than what is…
Thin Film CIGS Solar Cells, Photovoltaic Modules, and the Problems of Modeling
2013
Starting from the results regarding a nonvacuum technique to fabricate CIGS thin films for solar cells by means of single-step electrodeposition, we focus on the methodological problems of modeling at cell structure and photovoltaic module levels. As a matter of fact, electrodeposition is known as a practical alternative to costly vacuum-based technologies for semiconductor processing in the photovoltaic device sector, but it can lead to quite different structural and electrical properties. For this reason, a greater effort is required to ensure that the perspectives of the electrical engineer and the material scientist are given an opportunity for a closer comparison and a common language.…
Extending the Power Range of a Solar Inverter
2018
Solar inverters feature a minimum and maximum limit of the maximum power point voltage. Overcoming these limits leads to a disconnection of the power equipment, thus wasting the solar energy. In this paper, a solution to extend the power range of a solar inverter is presented. The proposed solution extends he minimum maximum power point limit of a commercial solar inverter by means of a battery energy storage system, including a DC/DC power converter. The battery energy storage system is connected in series to the photovoltaic module. If the photovoltaic module voltage drops below the minimum maximum power point limit, the battery energy storage system is enabled thus boosting the input vol…
The Fuzzy Concept of Idiom and What It Might Mean for Bilingual Dictionaries
2019
Linguistic categories were developed as tools for describing language systems and making them easier to learn. However, like many theoretical concepts and systems, they do not fully represent the real world and, in some cases, seek to imprison linguistic units within a well-ordered system – a procrustean bed as it were. Besides, although the most general categories are universal, the lower-ranking ones are often language-specific. Idiom (or phraseologism) is a very unclear linguistic concept, subject to never-ending debate. However, a strict adherence to categorisation is observable in practical bilingual lexicography and phraseography. This may lead to unwanted compartmentalisation and a…
Problem-Based Learning in Professional Studies from the Physiotherapy Students’ Perspective
2018
The aim of the study was to investigate how physiotherapy students using a problem-based learning approach develop into experts during higher education, and answers the question: How do physiotherapy students at bachelor’s level understand the problem-based learning approach while learning to become professionals? PBL is examined using interpretative phenomenological analysis (IPA) of longitudinal data written by 15 voluntary students from two different higher education institutions and collected during 3.5 years. The main results on the new way of learning strengthen earlier conceptions of the importance of reflection in the learning process. The PBL method activates a reflection process b…
