Context-awareness for multi-sensor data fusion in smart environments
2016
Multi-sensor data fusion is extensively used to merge data collected by heterogeneous sensors deployed in smart environments. However, data coming from sensors are often noisy and inaccurate, and thus probabilistic techniques, such as Dynamic Bayesian Networks, are often adopted to explicitly model the noise and uncertainty of data. This work proposes to improve the accuracy of probabilistic inference systems by including context information, and proves the suitability of such an approach in the application scenario of user activity recognition in a smart home environment. However, the selection of the most convenient set of context information to be considered is not a trivial task. To thi…
Automatic defect localization in VLSI circuits: A fusion approach based on the Dempster-Shafer theory
2017
Defect localization in Very Large Integration Cir-cuits (VLSI) requires to use multi-sensor information such aselectrical waveforms, emission microscopy images and frequencymapping in order to detect, localize and identify the failure. Eachsensor provides a specific kind of feature modeling the evidence.Thus, the defect localization in VLSI can be summarized asa problem of data fusion with heterogeneous and impreciseinformation. This study illustrates how to reproduce the humandecision for modeling and fusing the different multi-sensorfeatures by using the Demspter-Shafer theory. We propose notonly an automatic decision rule for mass functions computingbut also confidence intervals to quantif…
Multi-sensorie uzdevumi angļu valodas apguvei pirmsskolā
2016
Diplomdarba autore ir angļu valodas skolotāja pirmsskolā, un ir izveidojusi angļu valodas mācību programmu "Happy Child". 2015.gadā četri skolotāji mācīja angļu valodu saskaņā ar šo programmu piecās pirmsskolas izglītības iestādēs Latvijā. Vēlme pilnveidot angļu valodas mācību programmu ir mudinājusi izmēģināt dažādas pedagoģiskās pieejas, lai uzlabotu pirmsskolas vecuma bērnu angļu valodas vārdu krājuma apguvi; kā viens no risinājumiem ir rasts multi-sensoro uzdevumu izmantojums angļu valodas stundās. Par noslēguma darba formu tika izvēlēts diplomdarbs, lai veiktu pētījumu par multi-sensorajiem uzdevumiem saistībā ar pirmsskolas vecuma bērnu angļu valodas vārdu krājuma apguvi. Diplomdarba …
In Defense of Cities : On Negative Presentation of Urban Areas in Environmental Preference Studies
2019
This paper critiques a common research method, image-based studies, in assessing environmental preferences. The method is used, in particular, in the fields of environmental psychology, landscape studies, and health studies, here called empirical environmental preference studies or EEP studies. I argue that the established view in the EEP field that nature is inherently experienced as more aesthetically appealing and restorative than urban environments may be biased because of the image-based method. This paper presents a literature review of EEP studies, discussing them in a framework of environmental and everyday aesthetics. The conclusion is that EEP studies may strip cities of their phy…
Le traitement des expressions faciales au cours de la première année : développement et rôle de l'olfaction
2015
The first year of life is critical for the development of the abilities to process facial expressions. Olfaction and expressions are both strongly linked to each other, and it is well known that infants are able to multisensorially integrate their environment as early as birth. However, most of the studies interested in multisensory processing of facial expressions are restricted to the investigation of audio-visual interactions.In this thesis, we firstly aimed to resolve different issues concerning the ontogenesis of infants’ ability to process facial expressions. Our results allowed to specify the development of visual exploratory strategies of facial emotions along the first year of life…
Modern Multispectral Sensors Help Track Explosive Eruptions
2013
Due to its massive air traffic impact, the 2010 eruption of Eyjafjallajokull was felt by millions of people and cost airlines more than U.S. $1.7 billion. The event has, thus, become widely cited in renewed efforts to improve real-time tracking of volcanic plumes, as witnessed by special sections published last year in Journal of Geophysical Research, (117, issues D20 and B9).
Multisensorā pieeja veidojot bērnu rakstīt un lasītprasmes angļu valodas stundās
2016
Iemācīt pirmskolas vecuma bērniem lasītprasmi un rakstītprasmi ir svarīgs izaicinājums ikvienam skolotājam. Skolotāja izvēlētā pieejai, mācot bērnus, ir svarīga loma un tā var ietekmēt bērna panākumus lasīšanā un rakstīšanā nākotnē. Diplomdarba mērķis bija izpētīt multi-sensoro pieeju angļu valodas (kā svešvalodas) stundās, lai attīstītu bērna rakstītprasmi un lasītprasmi. Par pētījuma metodi tika izvēlēts gadījuma pētījums, kurš tika veikts 9 nedēļas Rīgas 234. Pirmsskolas izglītības iestādē. Diplomdarbā tika izmantotas sekojošas pētīšanas metodes: aptauja un novērošana. Diplomdarba autore novēroja 20 bērnus, kuri apmeklēja angļu valodas stundas, lai izpētītu viņu mācīšanās metodes un angļ…
Apperception as a Multisensory Process in Material Experience
2015
Visual perspective has dominated experience research in humantechnology interaction for decades now. The neglect of other sensory modalities is gradually being addressed by scholars and designers, who investigate user experience based on touch, smell, taste, sound and even expressive bodily interactions. In cognitive and affective processes, user experience is always multi-modal, not just regarding perceived multi-sensory information, but also while perceiving through one modality we mentally construct information relevant to the other senses. This article reports the results of an experiment, where participants (N = 52) appraised materials either only by touching them or only by seeing. Th…
