Classification of Heart Sounds Using Convolutional Neural Network
2020
Heart sounds play an important role in the diagnosis of cardiac conditions. Due to the low signal-to-noise ratio (SNR), it is problematic and time-consuming for experts to discriminate different kinds of heart sounds. Thus, objective classification of heart sounds is essential. In this study, we combined a conventional feature engineering method with deep learning algorithms to automatically classify normal and abnormal heart sounds. First, 497 features were extracted from eight domains. Then, we fed these features into the designed convolutional neural network (CNN), in which the fully connected layers that are usually used before the classification layer were replaced with a global averag…
Automatic Content Analysis of Computer-Supported Collaborative Inquiry-Based Learning Using Deep Networks and Attention Mechanisms
2020
Computer-supported collaborative inquiry-based learning (CSCIL) represents a form of active learning in which students jointly pose questions and investigate them in technology-enhanced settings. Scaffolds can enhance CSCIL processes so that students can complete more challenging problems than they could without scaffolds. Scaffolding CSCIL, however, would optimally adapt to the needs of a specific context, group, and stage of the group's learning process. In CSCIL, the stage of the learning process can be characterized by the inquiry-based learning (IBL) phase (orientation, conceptualization, investigation, conclusion, and discussion). In this presentation, we illustrate the potential of a…
A symmetric Galerkin boundary/domain element method for finite elastic deformations
2000
Abstract The Symmetric Galerkin Boundary Element Method (SGBEM) is reformulated for problems of finite elasticity with hyperelastic material and incompressibility, using fundamental solutions related to a (fictitious) homogeneous isotropic and compressible linear elastic material. The proposed formulation contains, besides the standard boundary integrals, domain integrals which account for the problem's nonlinearities through some (fictitious) initial strain and stress fields required to satisfy appropriate “consistency” equations. The boundary/domain integral equation problem so obtained is shown to admit a stationarity principle (a consequence of the Hu-Washizu one), which covers a number…
Angstens filosofi
2003
Angst har vært et viktig tema i nyere filosofi. Etter en kort introduksjon til fenomenologisk metode, gis det i denne artikkelen en presentasjon av Søren Kierkegaards, Martin Heideggers og Jean-Paul Sartres bidrag til angstens filosofi. Her relateres angstfølelsen til erfaring av intethet og til den grunnleggende eksistensielle friheten. Med utgangspunkt i denne filosofiske teorien gis en drøfting av hvordan angsten kan oppfattes som et uttrykk for en indre spenning. Til slutt vises det hvordan den filosofiske angstteorien kan relateres til konkrete angstformer og angstlidelser.
Rudolf Kassner et l'art de l'essai à Vienne (1900-1906)
2017
International audience; Rudolf Kassner (1873-1959) fréquente à la fin des années 1890 les milieux artistiques et intellectuels tant à Vienne qu'à Londres ou à Paris. Il noue alors des contacts avec de nombreux écrivains et artistes de son époque comme Hofmannsthal, Gide ou plus tard Rilke. Il décide d'écrire "sur la culture" et publie plusieurs ouvrages ainsi qu'une série d'essais consacrés la littérature, à l'esthétique ou à la philosophie. Influencé par ses lectures variées et cosmopolites, et porté par son admiration pour Nietzsche ou Kierkegaard, Kassner s'est imposé comme un commentateur attentif et clairvoyant des courants artistiques de son époque, en particulier de toutes les tendan…

The development of mobile banking services in a large Finnish financial organization
2018
The chapter, based on an ongoing qualitative study, provides answers to the following questions: what are the case organizations’ rationales in developing mobile banking services? how are customer perspectives considered in developing them? and what are the implications of digitalization and m-banking for the bank and the client? Based on the findings, m-banking is seen to allow ubiquitous availability and efficiency of service provision, offering a sound rationale for their development. The flipside is that digital and m-banking services dilute the human interaction, which challenges the rationale of improving the customer experience. The service development follows the software industry m…

Genetic-based evaluation of management units for sustainable vendace (Coregonus albula) fisheries in a large lake system
2022
The goal of the processing industry, trade and consumers is to get eco-labelled freshwater fish products from sustainable fisheries into the market as soon as possible. The fourth largest natural lake system in Europe, the Saimaa lake system supports a fishery for vendace (Coregonus albula). Certification of the fishery requires an understanding of population structure to help determine the number and spatial extent of management units. In this study, we analysed the genetic diversity of local vendace populations in the Saimaa lake system and aimed to identify the conservation and management units of vendace. Within the Saimaa, the genetic divergence between local populations of vendace was…
