The present work is aimed at presenting the data, methods and criteria that are being used for the assessment of ecosystem collapse risk in Italy.

Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.

2020

As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…

"Absolut ingen rädsla utan nyfikenhet" : tidigareläggning av finska – Case Nykarleby

2018

Nykarleby är en av de tvåspråkiga kommunerna som våren 2017 erhöll statens specialunderstöd för att tidigarelägga språkundervisningen i finska. Finskundervisningen i staden tidigarelades år 2016 till årskurs 1 men denna har redan konstaterats vara otillräcklig i en starkt svenskspråkig miljö. Därför har man under läsåret 2017–2018 planerat Kielistigen, ett språkprogram med målsättningen att stärka den kommunikativa finskan genom att börja med barn i femårsåldern samt integrera språket som en naturlig del av verksamheten från småbarnspedagogiken till grundskolan där språket integreras i övrig undervisning. nonPeerReviewed

Improving statistical classification methods and ecological status assessment for river macroinvertebrates

2016

Aquatic ecosystems are facing a growing number of human-induced stressors and the need to implement more biomonitoring to assess the ecological status of water bodies is eminent. This dissertation aims at providing tools to reduce the costs and improve the accuracy of freshwater benthic macroinvertebrate biomonitoring. To improve the cost-e ciency, we consider automated classi cation and develop a novel classi er suitable for complex macroinvertebrate image data. To enhance the accuracy of macroinvertebrate biomonitoring, we study the statistical properties of the Percent Model A nity index crucial to current Finnish biomonitoring and the factors a ecting these statistics. Finally, we perfo…

Tieto, valta ja vastuu erityislasten hoidossa

2016

Artikkelissa tarkastelen sitä, kuinka erityislasten vanhempien tieto ja asiantuntemus lasta koskevissa asioissa rakentuu ja kuinka siihen suhtaudutaan auttamistyön tilanteissa. Aineistoni koostuu vanhempien kokemuskertomuksista, joissa he kuvaavat erityislapsen vanhemmuuteen kasvua sekä kohtaamisia ammattilaisten kanssa auttamistyön kentillä. Tutkimukseni rakentaa kuvan epäsymmetriselle vallalle perustuvasta vuorovaikutuksesta, jossa ammattilaisen ja asiakkaan roolia määrittelevät kulttuuriset kategoriat vaikuttavat vanhempien mahdollisuuksiin osallistua auttamistyön neuvotteluihin. Näiden kategorioiden mukaan asiakkaan roolina on olla tiedon ja avun vastaanottaja, minkä seurauksena heidän …

Applying Semiautomatic Generation of Conceptual Models to Decision Support Systems Domain

2009

This paper presents a decision support system specification in the form of business use cases and a stereotyped conceptual model based on the specification. The use cases are based on generic user requirements and address cognitive biases. The specification can be used to set fixed and common terms among the project participants. Semiautomatic generation of the conceptual model is demonstrated with mixed results. While there are some shortcomings in the parsing and the result is dependent on the phrasing conventions used in the use cases, the conceptual model highlights the most essential entities in the domain and provides a base for further development phases. peerReviewed

A Study on the Assessment of Introductory Computational Thinking via Scratch Programming in Primary Schools

2018

Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to i…

Estimation of the Time-Variant Velocity of a Single Walking Person in Two-Dimensional Non-Stationary Indoor Environments Using Radio-Frequency Techni…

2020

Accurate estimation of the time-variant (TV) velocity of moving persons/objects in indoor spaces is of crucial importance for numerous wireless indoor applications. This article introduces a novel iterative procedure to estimate the TV velocity, i.e., TV speed and TV angle-of-motion (AOM), of a single moving person in 2D indoor environments by using radio-frequency (RF) techniques. The indoor area is equipped with a distributed 2 × 2 multiple-input multiple-output (MIMO) system. The proposed method is divided into two parts. In the first part, we estimate the path gains and the instantaneous Doppler frequencies by fitting the exact spectrograms of the complex channel gains of a 2D no…
