Head Tracking via Robust Registration in Texture Map Images.
1998
A novel method for 3D head tracking in the presence of large head rotations and facial expression changes is described. Tracking is formulated in terms of color image registration in the texture map of a 3D surface model. Model appearance is recursively updated via image mosaicking in the texture map as the head orientation varies. The resulting dynamic texture map provides a stabilized view of the face that can be used as input to many existing 2D techniques for face recognition, facial expressions analysis, lip reading, and eye tracking. Parameters are estimated via a robust minimization procedure; this provides robustness to occlusions, wrinkles, shadows and specular highlights. The syst…
Effects of apomorphine on orienting reaction in the rat
2009
Aim of the research was to study the possible relationship between rapid apomorphine-induced modifications of midbrain dopaminergic neuron activity and rapid modifications of a motor response triggered by sensory stimuli (sensory-motor integration. Following apomorphine administration, ANOVA test revealed significant decrease of head turning latency and duration. A change on dopamine release, leading to an inhibition or facilitation of dopamine-mediated responses to environmental stimuli, may be hypothesized.
Categorization in Discourse and Grammar
2016
This collection of papers addresses new trends in Cognitive Linguistics. Three parts of the book focus on Conceptual Metaphor Theory and Integration Network Analysis. Both the theoretical contributions and the empirical case studies stress the importance of contextual factors in the meaning making processes. They employ qualitative methods to analyze the use of metaphor in political discourse and in the conceptualization of emotions. The data sets include multimodal data, sign languages and co-speech gestures. The fourth part of the book contains two corpus-based studies. The fifth part concentrates on the grammatical categories of passive voice and aspect. One contribution discusses the pr…
Governing Performance in the Nordic Universities: Where Are We Heading and What Have We Learned?
2019
AbstractIn this final chapter, we revisit the overall aims of the volume and discuss the findings and implications for theory, policy, and practice. The general aim of the project has been to study the effects of the changing conditions of the environment under which Nordic higher education institutions operated during the period 2003–2013. A conceptual framework inspired by a typology developed by Johan P. Olsen was applied, focusing on various aspects of governance of universities and also stressing the ability of universities—as institutions—to resist, adapt, and respond to change initiatives from external and internal actors. Based on rich sources of data, including statistics, intervie…
On Optic Aphasia and Visual Agnosia
1991
Abstract The following is a translation from a paper by Freund published in two parts almost exactly 100 years ago. It is based on a talk he gave on February 23rd, 1888 at a meeting, chaired by Wernicke, of the Society of East German Psychiatrists at Breslau. A brief report of the proceedings of the meeting appeared in the same year under the title Einige Grenzfalle zwischen Aphasie und Seelenblindheit (Some borderline cases between aphasia and agnosia) (Freund, 1888). This is presumably why the first part, published in 1889, has the heading II before its title Ueber optische Aphasie und Seelenblindheit.
Crisis, Continuity, and Change in European Union Institutions: An Introduction
2020
This section offers an overview of how EU institutions have been affected by crises and how they have coped with them. The section finds that EU institutions have responded to polycrisis mainly by “muddling through” based on familiar ways of governing and by introducing incremental changes, and in some cases, also heading forward with new institutional arrangements or structures. The section hardly finds evidence of institutional breakdown or even of minor reductions in the role of EU institutions—either vis-a-vis other EU institutions or vis-a-vis member state institutions. To the contrary—the EU institutions have proven to be resilient and able to deal with crises by drawing on their alre…
Crisis and EU Foreign and Security Policy: An Introduction
2020
This chapter sums up the main findings in the four papers discussing the impact of various external crises on the development of the EU’s Common Foreign and Security Policy, the CFSP. Chapters discuss the EU’s foreign and security policy responses to the Russian annexation of Crimea and the ongoing war in Ukraine, the EU’s crisis management capacities, and the impact of crises on EU–US relations. Despite member states’ traditional reluctance to integrate further in this domain of EU policy, the CFSP is not breaking down. Instead, all the chapters suggest that the EU is able to cope with crises and that overall, crises and increased uncertainty have led to a strengthening of the CFSP mainly …
Development and validation in a group of industry workers, of an application for audiometric screening: A solution for social distance during COVID-1…
2020
In the context of the global COVID-19 pandemic, companies and institutions all over the world are trying to find the best ways to reorganize their activity, minimizing the contagion risk among their employees, so as to protect their health and prevent internal SARS-COV-2 outbreaks. The recent development of new communication technologies, such as smartphones and tablets, has paved the way for the development and implementation of different applications. Starting with the above issues, in this study, we wanted to investigate the efficacy of iAudiometry application developed by our research team for the detection of deficits in the auditory system. Furthermore, we analyzed the precision in de…
Synthetic individual binaural audio delivery by pinna image processing
2014
Purpose – The purpose of this paper is to present a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener’s pinna. Design/methodology/approach – The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener’s head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source. Findings – A preliminary localization test shows that the model is able to statically render the elevation of a vi…
Gaistošo organisko savienojumu emisijas no kuņģa vēža audiem un to potenciālā bioloģiskā saistība
2018
Gaistošā organiskā savienojuma (VOC) emisija, ko var novērot izelpā, ir strauji augoša diagnostikas metode audzēju izmeklēšanā. VOC ir savienojums, kam istabas temperatūrā ir augsts tvaika spiediens, kas veicina tā iztvaikošanu gāzes formā. Šo gāzi var noteikt cilvēka audos un šķidrumos.( Haick et al 2014) Galvenokārt ir pētīta VOC saistība ar plaušu vēzi. Taču aizvien vairāk tiek veikti pētījumi, lai noteiktu, kādas ir iespējas VOC pielietot arī kuņģa audzēja gadījumā. Tā kā VOC molekula spēj mijiedarboties ar šūnu metabolītiem, apkārtējo vido, mikrobiem u.c., ir grūti saprast tā rašanās vietu. Šajā pētījumā tiks izmeklētas potenciālās savienojuma vietas, no kurām tas cēlies. Ir dažādi vie…
