SingleChannelNet : A model for automatic sleep stage classification with raw single-channel EEG
2022
In diagnosing sleep disorders, sleep stage classification is a very essential yet time-consuming process. Various existing state-of-the-art approaches rely on hand-crafted features and multi-modality polysomnography (PSG) data, where prior knowledge is compulsory and high computation cost can be expected. Besides, it is a big challenge to handle the task with raw single-channel electroencephalogram (EEG). To overcome these shortcomings, this paper proposes an end-to-end framework with a deep neural network, namely SingleChannelNet, for automatic sleep stage classification based on raw single-channel EEG. The proposed model utilizes a 90s epoch as the textual input and employs two multi-conv…
Image inpainting using directional wavelet packets originating from polynomial splines
2020
The paper presents a new algorithm for the image inpainting problem. The algorithm is using a recently designed versatile library of quasi-analytic complex-valued wavelet packets (qWPs) which originate from polynomial splines of arbitrary orders. Tensor products of 1D qWPs provide a diversity of 2D qWPs oriented in multiple directions. For example, a set of the fourth-level qWPs comprises 62 different directions. The properties of the presented qWPs such as refined frequency resolution, directionality of waveforms with unlimited number of orientations, (anti-)symmetry of waveforms and windowed oscillating structure of waveforms with a variety of frequencies, make them efficient in image pro…
Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions
2020
Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.
Milk Thistle (Silybum Marianum L.) as a Novel Multipurpose Crop for Agriculture in Marginal Environments: A Review
2022
Milk thistle (Silybum marianum (L.) Gaertn.) is a versatile crop that has adapted to the broadly different soil and environmental conditions throughout all continents. To date, the fruits (“seeds”) of the plant are the only reliable source of silymarin, which, given its recognized therapeutic effects and its many present and potential uses, has led to a significant re-discovery and enhancement of the crop in recent years. Overall, although many studies have been carried out globally on the bioactivity, phytochemistry, and genetics of milk thistle, few and discontinuous research activity has been conducted on its basic agronomy as well as on the farm opportunities offered by the cultivation …
Constructing co-presence through shared VR gameplay
2021
This study analyzes how participants playing VR games construct co-presence and shared gameplay. The analysis focuses on instances of play where one person is wearing the VR equipment, and other participants are located nearby without the ability to directly interact with the game. We first show how the active player using the VR equipment draws on talk and embodied activity to signal their presence in the shared physical environment, while simultaneously conducting actions in the virtual space, and thus creates spaces for the other participants to take part in gameplay. Second, we describe how other participants draw on the contextual configurations of the moment in displaying co-presen…
Sosiaalityö ja lasten pahoinpitely : kuka puhuu lasten pahoinpitelystä asiantuntijana?
2008
Tutkielmani aiheena on lasten pahoinpitely, jota lähestyn sosiaalityön näkökulmasta tarkastellen miten lasten pahoinpitelyä sosiaalityön erilaisilla professionaalisilla kentillä määritellään ja kenen näkökulmasta ongelmaa lähestytään. Tutkimuksen kohteena ovat niin sosiaalityön viranomaiskäytännöissä elävät puhe- ja toimintatavat kuin sosiaalityön tutkimuksen tapa nimetä ja tulkinta ongelmaa. Tutkimustavoitteenani on vastata kysymykseen ketkä puhuvat lasten pahoinpitelystä asiantuntijana. Konstruktionistinen tutkimusote kulkee läpi koko tutkimukseni kuvaten sitä, miten lasten pahoinpitelystä on ylipäätään tullut sosiaalinen ongelma. Tutkielman teoreettisen viitekehyksen muodostaa lasten pah…
Eläköitymisen vaikutukset sukupolvien välisiin hyvinvointieroihin limittäisten sukupolvien malleissa : kjallisuuskatsaus malleihin ja aiempiin tutkim…
2015
Tämän työn tarkoitus on esitellä limittäisten sukupolvimallien ja kuluttajan käyttäytymisen teoreettiset perusteet sekä arvioida eläköitymisen merkitystä sukupolvien välisen hyvinvoinnin jakautumisessa aiemman empiirisentutkimuksen ja kirjallisuuden pohjalta. Eläköitymisen kokonaistaloudellisten muutosten tutkiminen edellyttää sukupolvittaista jaottelua. Tässä työssä tähän jaotteluun käytetyt menetelmät koostuvat sukupolvitilinpidosta ja numeerisista limittäisten sukupolvien malleista. Erityisesti limittäisten sukupolvien mallit kykenevät arvioimaan harjoitetun finanssipolitiikan kestävyyttä sukupolvien välisen hyvinvoinnin näkökulmasta. Mallien laskelmat ottavat huomioon eläköitymisen väli…

About the reinterpretation of the Ghosh model as a price model
2001
The Ghosh model assumes that, in an input-output framework, each commodity is sold to each sector in fixed proportions. This model is strongly criticized because it seems implausible in the traditional input-output field. To answer to these critics, Dietzenbacher stresses that it can be reinterpreted as a price model: the Leontief price model is equivalent to the Ghosh model when this one is interpreted as a price model. This paper shows that the interpretation of the Ghosh model as a price model cannot be accepted because Dietzenbacher makes a strong assumption, dichotomy, while the Ghosh model does not determine prices...
T9+HUD: Physical Keypad and HUD can Improve Driving Performance while Typing and Driving
2016
We introduce T9+HUD, a text entry method designed to decrease visual distraction while driving and typing. T9+HUD combines a physical 3x4 keypad on the steering wheel with a head-up-display (HUD) for projecting output on the windshield. Previous work suggests this may be a visually less demanding way to type while driving than the popular case which requires shifts of visual attention away from the road. We present a prototype design and report first results from a controlled evaluation in a driving simulator. While driving, the T9+HUD text entry rate was equal compared to a dashboard-mounted touchscreen device, but it reduced lane deviations by 70%. Furthermore, there was no significant di…
