Cortical networks show characteristic recruitment patterns after somatosensory stimulation by pneumatically evoked repetitive hand movements in newbo…
2022
Abstract Controlled assessment of functional cortical networks is an unmet need in the clinical research of noncooperative subjects, such as infants. We developed an automated, pneumatic stimulation method to actuate naturalistic movements of an infant’s hand, as well as an analysis pipeline for assessing the elicited electroencephalography (EEG) responses and related cortical networks. Twenty newborn infants with perinatal asphyxia were recruited, including 7 with mild-to-moderate hypoxic–ischemic encephalopathy (HIE). Statistically significant corticokinematic coherence (CKC) was observed between repetitive hand movements and EEG in all infants, peaking near the contralateral sensorimotor…

Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
Biogas composition and upgrading to biomethane
2009
Saija Rasin tutkimus osoittaa, että jätteistä tai energiakasveista tuotettua biokaasua voidaan hyödyntää sähkön ja lämmön tuotantoon. Biokaasua voidaan käyttää jalostettuna myös korkealaatuista polttoainetta vaativissa kohteissa, kuten ajoneuvoissa ja polttokennoissa. Fossiilisten polttoaineiden korvaaminen uusiutuvilla polttoaineilla, esimerkiksi biokaasulla, vähentää merkittävästi kasvihuone- ja muita haitallisia päästöjä. Biokaasun pääkomponentit ovat metaani ja hiilidioksidi, ja lisäksi se voi sisältää pieniä pitoisuuksia energiakäyttöä haittaavia yhdisteitä, joiden määrä ja laatu vaihtelevat. Nämä yhdisteet voivat esimerkiksi estää koko teknologian käytön tai lyhentää laitteistojen huo…
Embodied Meter Revisited : Entrainment, Musical Content, and Genre in Music-Induced Movement
2022
Previous research has shown that humans tend to embody musical meter at multiple beat levels during spontaneous dance. This work that been based on identifying typical periodic movement patterns, or eigenmovements, and has relied on time-domain analyses. The current study: 1) presents a novel method of using time-frequency analysis in conjunction with group-level tensor decomposition; 2) compares its results to time-domain analysis, and 3) investigates how the amplitude of eigenmovements depends on musical content and genre. Data comprised three-dimensional motion capture of 72 participants’ spontaneous dance movements to 16 stimuli including eight different genres. Each trial was subjected…
Segmentation boundaries in accelerometer data of arm motion induced by music : online computation and perceptual assessment
2022
Segmentation is a cognitive process involved in the understanding of information perceived through the senses. Likewise, the automatic segmentation of data captured by sensors may be used for the identification of patterns. This study is concerned with the segmentation of dancing motion captured by accelerometry and its possible applications, such as pattern learning and recognition, or gestural control of devices. To that effect, an automatic segmentation system was formulated and tested. Two participants were asked to ‘dance with one arm’ while their motion was measured by an accelerometer. The performances were recorded on video, and manually segmented by six annotators later. The annota…
International Student Migration in Finland
2021
There is increasing attention on the retention of international students with many stakeholders desiring to keep international students for long-term economic growth. This study examines the factors affecting international students to stay in Finland five years after initial enrolment with particular focus on the role graduation plays in students staying or leaving. Tracking 11 (years) entering cohorts for five years across national (Finland) data registries, we found evidence of an inverse relationship between graduation, degree type, and the probability of staying; higher the degree level of graduation, the decrease in probability an international student stays. We conclude that while gra…
Organisational Drivers and Challenges in Circular Economy Implementation : An Issue Life Cycle Approach
2022
Business is a significant cause of various global sustainability challenges addressed by the Circular Economy (CE), making companies instrumental in the transition from a linear economic model to a circular one. While drivers and challenges in corporate CE implementation have been researched on an organisational level, a more detailed understanding is needed regarding their contextual nature and interplay with the evolution of CE implementation in a company. Utilising issue life cycle theory, this study contributes to the literature on CE implementation in business by displaying differences in corporate CE implementation drivers and challenges, relating to the time since starting, and the …

Control and management of multi-access wireless networks
2005
Eero Wallenius tutki väitöskirjassaan langattomiin monipääsy- ja monipalveluverkkoihin liittyviä kysymyksiä. Hän selvitti 3/4G ja WLAN -verkkojen palvelun laadun laskutuksen säätöä ja hallintaa sekä esitti laskutus- ja säätömalleja analyysien ja simulointien avulla.Palvelun laadun ja laskutuksen suhdetta on jo aikaisemmin tutkittu. Tutkimuksen tulokset ovat helposti sovellettavissa langattomiin 3/4G ja WLAN -verkkoihin. Wallenius tutki myös tilaajan hyväksymissuhdetta palvelun hinnoitteluun. Hän esitti operaattorien tarpeisiin luodun hallintamallin verkkopalvelujen hinnoitteluun ja käyttöön verkon kuormituksen säädöllä. Hän loi myös dynaamisen mallin verkkopalvelujen hinnoittelun optimointi…
