Webcam based display calibration
2012
International audience; We present an automatic method for measuring the tone response curve of display devices based on visual methods, where the eye is replaced by an end-user, uncalibrated camera, such as a webcam. Our approach compares a series of halftoned patches of known covering ratio with a continuous series of tone patches for each ratio. Both patches are shot by a camera that is used as a virtual eye to evaluate the luminance difference. By an iterative process, the continuous tone value is adjusted while compared with the perceived level of the halftoned patch. When the camera does not see any difference between the patches or a minimal difference, the luminance level of the con…
Oppressive Faces of Whiteness in Walter Mosley’s "Devil in a Blue Dress"
2018
Walter Mosley’s Devil in a Blue Dress contributes significantly to the literary debate on the definition of whiteness. The socio-historical construction of whiteness emerging from the novel is amplified by white imagery dovetailing with the claims made about white people directly. For the African American first person narrator, Easy Rawlins, living in post-World War II Los Angeles, whiteness mostly spells terror. The oppressive faces of whiteness consist in the following trajectories: property relations, economic exploitation, labour relations, the legal system, different miens of oppressive white masculinity denigrating blackness, spatial dynamics of post-World War II Los Angeles and the w…
Customer Environmental Values and Their Contribution to Loyalty in Industrial Markets
2016
Concern over the effect of industries on the natural environment is growing on a multitude of levels. This study examines the effects of how perceptions of (a) environmental values, (b) green image and (c) perceived value of industrial customers influence their loyalty towards suppliers in existing relationships, and how the length of B2B relationships may moderate these linkages. A conceptual framework is developed and data are collected from a global sample (N =121) of B2B customers. We find that both green image and perceived value have a direct positive link with customer loyalty and that environmental values are positively linked to the green image of the supplier. Moreover, the effect…
Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review
2018
This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
"On-the-go" multispectral imaging system embedded on a track laying tractor to characterize the vine foliage
2015
Mutispectral imaging systems are widely used in remote sensing for Precision Viticulture. In this work, this technique was applied in the proximal sensing context to characterize vine foliage. A mobile terrestrial experimental system is presented, composed of a GPS receiver, a multi-spectral camera acquiring visible and near infrared images, and a Greenseeker RT-100 which measures the Normalized Difference Vegetative Index (NDVI). This optical system observes vine foliage in the trellis plan, in natural sunlight. The experimental field is planted with Chardonnay, Pinot Noir and Meunier cultivars in a latin squared pattern. In 2013, six datasets were acquired at various phenological stages.S…
Contribution to thermal behaviour study of lithium-ion battery for electric and hybrid electric vehicle
2014
The main objectives of this study are to provide the essential information on the thermal behaviour of the battery cells for automotive purpose especially for EVs and HEVs through experimental work in order to develop an effective 3D electro-thermal model for lithium ion battery cells and pack. The experimental study is focusing on the distribution of temperature at various points of the battery cell surface, impact of different constant discharge rates, and also the importance of cooling system on the battery temperature behaviour. This thesis highlights the battery cell temperature under abuse discharge condition and the impact of stacking the battery cells inside the battery pack. Impact…
Ķermeņa tēla uztvere un fizisko aktivitāšu līmenis saistībā ar subjektīvo labklājību
2019
Bakalaura darba mērķis bija apkopot šobrīd zināmo informāciju par subjektīvo labklājību, fizisko aktivitāti un ķermeņa tēla uztveri. Ne mazāk svarīgi bija izprast fiziskās aktivitātes līmeņa un ķermeņa tēla uztveres ietekmi uz subjektīvo labklājību. Kā arī mērķis bija ievākt datus, izmantojot aptaujas, lai noskaidrotu vai pastāv statistiski nozīmīga saistība starp subjektīvo labklājību un ķermeņa tēla uztveri un fiziskās aktivitātes līmeni. Pētījumā piedalījās 148 brīvprātīgie respondenti vecumā no 16 līdz 53. Visiem respondentiem tika veikti subjektīvās labklājības mērījumi izmantojot Apmierinātības ar dzīvi skalu (SWLS) (Diener et al., 2006). Kā arī katram tika veikti fiziskās aktivitātes…
Joannesa Molanusa recepcja trydenckiego dekretu o obrazach
2020
Joannes Molanus, teolog, rektor Uniwersytetu w Louvain napisał obszerny traktat, który miał być pomocą dla biskupów i księży, w szczegółowym zastosowaniu ogólnego dekretu soborowego o obrazach. Molanus odrzucił te sposoby obrazowania, które nie są oparte na Biblii, a na apokryfach. Zerwał także z niektórymi przedstawieniami alegorycznymi czy wschodnimi. Stworzył teologiczne podstawy pod katolicką sztukę sakralną, która jest obecna w kościołach do dziś. Artykuł przedstawia analizę dekretu Soboru Trydenckiego o obrazach (1), życie i twórczość Molanusa (2), kontekst czasów Reformacji, w których żył Molanus, zwłaszcza w aspekcie obrazoburstwa (3), następnie zostaje omówiony traktat o obrazach M…
