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…
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…

Sensory modalities and mental content in product experience
2015
Contemporary research in human-technology interaction emphasises the need to focus on what people experience when they interact with technological artefacts. Understanding how people experience products requires detailed investigation of how physical design properties are mentally represented, and the theorisation of how people represent information obtained through different modalities still needs work. The objective of this study is to investigate how people experience modality-related affective aspects of products, using the psychological concept of mental content. For this purpose, we adopt the framework of user psychology, which is the sub-area of psychology involved with investigating…
Fall Detection Using Location Sensors and Accelerometers
2015
The rapid aging of the world's population is driving the development of pervasive solutions for elder care. These solutions, which often involve fall detection with accelerometers, are accurate in laboratory conditions but can fail in some real-life situations. To overcome this, the authors present the Confidence system, which detects falls mainly with location sensors. A user wears one to four tags. By detecting tag locations with sensors, the system can recognize the user's activity, such as falling and then lying down afterward, as well as the context in terms of the location in the home. The authors used a scenario consisting of events difficult to recognize as falls or nonfalls to comp…
Simplicity and the art of something more: A cognitive-semiotic approach to simplicity and complexity in human-technology interaction and design exper…
2018
In human–technology interaction, the balance between simplicity and complexity has been much discussed. Emphasis is placed on the value of simplicity when designing for usability. Often simplicity is interpreted as reductionism, which compromises both the affective nature of the design and usability itself. This paper takes a cognitive–semiotic approach toward understanding the dynamics between the utilitarian benefits of simplicity in design and the art of something more: considerate complexity. The cognitive–semiotic approach to human–technology design experience is a vehicle for explaining the relationship between simplicity and complexity, and this relationship’s multisensory character …
