A Statecharts-Based Approach for WSN Application Development
2020
Wireless Sensor Network (WSN) software development challenges developers in two main ways: through system programming, which requires expertise in hardware and network management
Alkuvaiheen S2-oppijoiden käsityksiä puheen ymmärtämisen vaikeuksista ja kompensaatiostrategioista
2015
This article examines adult L2 Finnish learners’ perceptions of listening difficulties and compensatory strategies in everyday situations. The data consist of questionnaire answers (N = 202) and five semi-structured interviews. The answers were grouped according to the reasons why listening difficulties were experienced. The number of times each reason was mentioned was calculated in order to find out to what extent the reasons were shared by the group. The interviews were used as a complementary resource for analysing the questionnaire answers. The results suggest that listening difficulties were most commonly attributed to speech rate, colloquial language and unfamiliar words, and it is a…
Monitoring of stress distribution in damaged small-scale masonry walls by using two innovative sensors
2023
Structural Health Monitoring (SHM) represents a strategic solution for the preservation of cultural heritage buildings. Existing masonry structures often suffer reductions in mechanical performances due to physiological aging of material constituents, external actions, and effect of catastrophic natural events. In many cases, the prompt prediction of damage in masonry elements is difficult and it can cause sudden collapses, compromising the safety of people. The proposed experimental study examines the effectiveness of two low-cost and innovative stress sensors, i.e. piezoelectric and capacitive stress sensors, for SHM of masonry structures. To this scope, the sensors were embedded in the m…
Sensorimotoro funkciju novērtēšana cilindra un stūra testā pelēm pēc modelēta insulta
2021
Insults ir akūta neiroloģiska disfunkcija, kas izraisa neiroloģiskas, sensorimotoras un uzvedības izmaiņas. Lai izprastu insulta patoloģiskos mehānismus un izstrādātu jaunas terapijas, insults tiek modelēts eksperimentāli. Stūra un cilindra uzvedības testus izmanto, lai novērtētu sensorimotorās funkcijas grauzējiem. Maģistra darba mērķis ir izvērtēt cilindra un stūra testa pielietojumu modelēta insulta gadījumā pelēm divu mēnešu periodā. Pētījumā secināts - lai mazinātu peļu pierašanu un neaktivitāti, cilindra un stūra testus ieteicams veikt pārmaiņus, kā arī ne pārāk bieži. Pētījuma sākumā ieteicams veikt pirms operācijas griešanās preferences novērtēšanu. Precīzākai novērtēšanai ieteicams…
Multiskilled in many ways : Ghanaian Female Journalists Between Job and Home
2020
In Ghana, feminisation of journalism profession has become a fact: more girls are entering journalism programmes in the Universities, and the number of women employees are growing in the newsrooms. The problem of balancing worktime arrangements (e.g. irregular and unpredictable work schedules, weekend work and long working hours) with equally important domestic obligations are familiar to most female journalists around the globe. Even in countries with well-developed social support structures, and well-defined labour laws, the current nature of journalism worktime arrangements impedes many female journalists to achieve work–life balance. For most Ghanaian female journalists, the culturally …
Spherical Top Theory and Molecular Spectra
2011
In this article, we present an overview of the present state of the art of the theory of high-resolution spherical-top spectra in the framework of the effective Hamiltonian approach. We describe the specific features of this class of molecules to explain the basic concepts of the theoretical methods used for the analysis (line positions and intensities) and the simulation of absorption (including pure rotation) and Raman spectra of such species. The non conventional formalism that we use is essentially based on irreducible tensor methods and is especially adapted to computational treatments and global analyses of complex interacting band systems. We give examples concerning mainly methane (…
Vertikaalihypyn korkeuden arviointi 3D-kiihtyvyysanturilla ja lajinomaisen kuormituksen vaikutukset hyppyyn
2016
Sensoreihin perustuvat menetelmät ovat yleistyneet urheilutestauksessa viime vuosina. Tarkoituksena oli selvittää hyppääjän kenkään kiinnitettävään 3D-kiihtyvyysanturiin perustuvan menetelmän validiteettia vertikaalihypyn korkeuden arvioinnissa. Voimalevyn lentoaikamenetelmää käytettiin kiihtyvyysanturimenetelmän validiteettianalyysissä ja lajikohtaisten kuormitusasetelman vertikaalihypyt arvioitiin kiihtyvyysanturimenetelmällä. Hyppysarjojen korkeimmat hypyt arvioitiin lisäksi voimalevyn lähtönopeusmenetelmällä. Kiihtyvyysanturimenetelmässä käytettiin urheilijan kenkään kiinnitettävää The Stride Sensor Bluetooth® Smart (Polar Electro Oy, Kempele, Suomi) -sensoria. Hyppytestit suoritettiin …
Characterizing a dc-SQUID and a Mo/TiW/Cu -trilayer transition-edge sensor array
2017
Tutkielmassa määritettiin uuden suprajohtavan kvantti-interferenssilaitteen ja 256 pikseliä sisältävän sirun transitioreunailmaisimien ominaisuuksia. Komponentit vaativat erittäin matalia lämpötiloja ja suojauksen suurilta magneettikentiltä muuttuakseen suprajohtaviksi. Tärkeimmät mitatut ominaisuudet olivat suprajohtavan kvantti-interferenssilaitteen signaalin vahvistuskerroin sekä kohina ja transitioreunailmaisimen transitiolämpötila, normaalitilan vastus, virta-jännite-käyttäytyminen, sekä kohina. Motivaationa tutkimukselle oli etsiä käytetyn mittalaite kokonaisuuden herkkyyden rajat sekä pyrkiä sovittamaan teoreettista mallia transitioreunailmaisimen kohinan ymmärtämiseksi. Korkean taaj…
Sensors for the monitoring of analytes in the sweat
In the last decade, can be found an exceptional growth in research activity relating to the development of wearable devices, capable of continuously monitoring the health conditions of the wearer by analyzing body fluids such as blood, urine, saliva, tears and sweat. Among the body fluids available, sweat is a biofluid of particular interest, as it allows a non-invasive, continuous and comfortable collection. Human sweat contains useful information on the health of an individual and therefore is an excellent biofluid for the detection of specific analytes. The most abundant ions in the sweat are Na+ and Cl- (10 - 100 mM), and their monitoring is useful in patients with cystic fibrosis. Othe…
Application of Periodic Frames to Image Restoration
2014
In this chapter, we present examples of image restoration using periodic frames. Images to be restored were degraded by blurring, aggravated by random noise and random loss of significant number of pixels. The images are transformed by periodic frames designed in Sects. 17.2 and 17.4, which are extended to the 2D setting in a standard tensor product way. In the presented experiments, performances of different tight and semi-tight frames are compared between each other in identical conditions.
