Hybridilämmitysjärjestelmän tiedonkeruu ja -analysointi omakotitalokohteelle
2013
Opinnäytetyössä suunniteltiin ja toteutettiin tiedonkeruujärjestelmä omakotitalon lämmitysjärjestelmälle, jonka muodostavat maalämpöpumppu, aurinkokeräimistö ja vesikiertoinen kamina. Lämminvesivaraajan ja tilojen lämmityksen lisäksi aurinkokeräimistö ja kamina pystyvät esilämmittämään maalämpöpumpun keruunestettä ja lämmittämään lämpöpumpun maapiiriä. Tiedonkeruun avulla saadun datan ja lähdekirjallisuuden avulla järjestelmän toimivuutta ja optimaalista käyttöä arvioitiin. Työn tarkoituksena oli myös selvittää vastasivatko aurinkokeräimelle ja kaminalle ilmoitetut hyötysuhteet mitattuja. Työn pohjaksi käytiin läpi suomalaisen pientalon lämmöntarvetta. Toteutettu tiedonkeruujärjetelmä on ka…
Isometric force-time parameters in monitoring of strength training : with special reference to acute responses to different loading resistances
2017
The aim of the present series of studies was to investigate acute neuromuscular responses to (1) different strength training loadings and using (2) different external resistances. In addition, chronic adaptations and dynamic performances were compared to (3) the changes in isometric force-time parameters at the group level, and to (4) the individual timing of the improvement in the rate of force development (RFD) due to hypertrophic or maximum strength followed by power strength training periods. The latter one was achieved by systematic, repeated monitoring. Sixty-nine physically active men (20-35 yrs), but not experienced in resistance training, took part in the present series of studies.…
Reliability and validity of time domain heart rate variability during daily rout¡ne activities : an alternative to the morning orthostatic test?
2017
Summary Study aim: To determine the reliability and validity of a time domain heart rate variability (HRV) index during free-living physical activity (FLPA). Material and methods: Eight white-collar workers participated in this study. RR intervals (time between consecutive R-peaks of the PQRS complex) were recorded using the Polar V800 heart rate (HR) monitor upon awakening and at work on 16 different days. A total of 127 cycles of sitting periods followed by walking breaks were included for consecutive pairwise analysis for reliability. The HR values from the orthostatic test (OT) were compared with the corresponding values at work. Results: The HR values showed high levels of repeatabilit…
Do testate amoebae communities recover in concordance with vegetation after restoration of drained peatlands?
2016
The environmental importance of peatlands has stimulated efforts to restore their specific ecosystem structure and functions. Monitoring and assessment of the ecological state of the peatland is fundamental in restoration programmes. Most studies have focused on the responses of vegetation and, to a lesser extent, on testate amoebae (TA). To our knowledge, none have investigated whether these two groups show concordance in the context of restoration of drained peatland. Here we assess community concordance between TA and vegetation in boreal peatlands belonging to four different land use management classes (natural, drained, restored 3–7 years ago, and restored 9–12 years ago). TA and veget…

Maternal homework assistance and children's task-persistent behavior in elementary school
2018
The present study used a sample of 365 children to investigate the longitudinal associations between maternal homework assistance (i.e., help, monitoring, and autonomy granting) and children's task-persistent behavior in learning situations from grade 2 to grade 4 of elementary school. Also, the extent to which task-persistent behavior plays a role in the links between parental homework assistance and children's academic performance was examined. The results showed that the more autonomy granting mothers reported, the more task-persistent behavior children exhibited; and more task-persistent behavior children exhibited, the more autonomy their mothers granted. In contrast, the more mothers …
Understanding evolving organisational issues in social media
2017
The aim of this dissertation is to better understand the spread of issues in social media, a relatively new phenomenon that is not fully understood in academia. The phenomenon has also captured the interest of organisations, as it may cause or coincide with organisational crises. Following issue spread is not easy, as issues emerge in dynamic interaction amongst many actors who are engaged in voluminous debate within varying media environments. This research was based on insights from different disciplines – in particular, communication sciences and information systems. It utilised quantitative, qualitative and mixed methods. Literature reviews provided a solid basis, whereas various cases …
Communication in turbulent times : exploring issue arenas and crisis communication to enhance organisational resilience
2017
This book is characterised by a broad approach towards corporate communication, emphasising change and crisis. The focus is not on crises as an exceptional situation but rather on broader volatility in the environment. The purpose of this book is to increase the understanding of multi- stakeholder communication concerning organisational issues and crises. From the perspective of organisational management, this book clarifies how communication contributes to organisational resilience—the ability to adapt to a changing environment and mitigate emergency crises. In todays’ world, change is not the exception but a constant presence. Moreover, issues and risks occur that may grow to become crise…
Practices and Infrastructures for Machine Learning Systems : An Interview Study in Finnish Organizations
2022
Using interviews, we investigated the practices and toolchains for machine learning (ML)-enabled systems from 16 organizations across various domains in Finland. We observed some well-established artificial intelligence engineering approaches, but practices and tools are still needed for the testing and monitoring of ML-enabled systems. Peer reviewed
Hydrogeologinen WSN-ympäristömonitorointi : tapaustutkimus Kaitforsin patoalueen pohjavesien korkeusseurannan pilottijärjestelmästä
2017
Tämän pro gradu -tutkielman tavoitteena on selvittää Kaitforsin patoalueelle toteutetun pohjavesien monitorointiin Kokkolan yliopistokeskus Chydeniuksessa kehitetyn pilottijärjestelmän näkökulmasta, millaisin menetelmin vedenkorkeuksien ja veden laadun monitorointia voidaan IoT:n ja langattomien sensoriverkkojen asettamista lähtökohdista automatisoidusti suorittaa. Tämän lisäksi tutkimuksen tavoitteena on selvittää automatisoidun ympäristömonitoroinnin nykytilaa ja siihen kytkeytyviä kehityssuuntauksia. Tutkimuksessa perehdytään myös Kaitforsin patoalueelle asennetun pilottijärjestelmän IEEE 802.15.4 -standardiin perustuvaan langattoman sensoriverkon toimintaan ja siihen kytkeytyneiden sens…
