First-principle modelling of plasmas in General Relativity KU Leuven

Rony Keppens
Plasma-astrophysics, Universiteit van Amsterdam

It is an exciting moment for astrophysical research: for the very first time, we can directly observe the black hole that lies at the centre of our Galaxy. Such mysterious objects do not emit any light; what we can detect is only the radiation due to the surrounding plasma, i.e. a tenuous gas of charged particles accelerated to extremely high energies. The mechanisms behind our observations can be studied with simulations, i.e. computer ...

Trafficmodels and general relativity Ghent University

Pieter Audenaert
Department of Information technology

Driving used to enable people to travel quickly. However, traffic congestion has become a major problem and it is still getting worse. The last years, the total congestion time increased enormously, e.g. in Flanders on average with 10% annually. People that get stuck in traffic jams lose valuable time, but congestion also increases the fuel consumption, the carbon footprint and it deteriorates the air quality.

While we will not be ...

Strategic Research Programme: Conceptual Density Functional Theory: Towards a general treatment of chemical reactivity and design of molecules with optimal reactivity properties (SRP9) Vrije Universiteit Brussel

Frank De Proft, Paul Geerlings
Chemistry
Focusses on (1) Development and/or implementation of reactivity indices, (2) Use and study of reactivity indices within the framework of principles, such as Hard and Soft Acids and Bases principle, the principle of maximum hardness or the principle of electronegativity equalization, (3) use of concepts and principles in application in organic and inorganic chemistry, catalysis, biochemistry, and nanochemistry

On the simulation of supernovae and their gravitational wave emission in numerical relativity KU Leuven

Tjonnie Li
Theoretical Physics, Department of Electrical Engineering (ESAT)

According to general relativity, gravitational waves can be emitted by a supernova. The expected waveform from such an event can be simulated in the framework of numerical relativity. However, the complete simulation of a supernova is a challenge, since it involves not only general relativity and plasma physics, but also neutrino interactions. I investigate how we can improve existing simulation schemes to obtain ...

Addressing alcohol use in general practice - a community-oriented approach KU Leuven

Mieke Vermandere, Bert Aertgeerts
Academic Center for General Practice

Background

Even though often socially accepted, alcohol is one of the leading risk factors for poor health and death in the world. Therefore, the world health organization (WHO) promotes the integration of alcohol-related early identification and brief intervention (EIBI) in general practice as one of the most cost-effective strategies to address this burden. However, implementation of EIBI in general practice ...

Optimalisation of the interRAI Suite of Instruments as a tool for assessing and facilitating oral health and evaluation of its relation to general health of frail older persons. KU Leuven

Joke Duyck
Population Studies in Oral Health, TRANSFORM, Leuven Biostatistics and Statistical Bioinformatics Centre (L-BioStat), Academic Center for General Practice
The generally poor oral health in frail elderly can be optimised by using the interRAI Suite of Instruments (interRAI-SoI), designed to assess an older persons need for care. The instrument consists of a questionnaire on important health as-pects. Algorithms translate the data into alerts that trigger assessment protocols, which in turn lead to individual care paths. The interRAI-SoI also includes non-vali-dated basic oral health related ...

Psychological Contract Breaches, Organizational Citizenship Behavior, and Identification Mechanisms: Insights from the perspective of general employees and ethnic minority employees KU Leuven

Karel De Witte
Work, Organisational and Personnel Psychology

SUMMARY

Psychological contract breaches, organizational citizenship behavior, and identification mechanisms: Insights from the perspective of general and ethnic minority employees.

PhD researcher: Pinar Tufan

Supervisors: Professor Karel De Witte and Professor Hein Wendt

 

A psychological contract (PC) framework may offer powerful insights into contemporary employment relationships (Guest & Conway, ...

Reasoning between theories. A general framework for doing epistemology with logic. (FWOTM465) Vrije Universiteit Brussel

Patrick Allo
Philosophy - Moral Sciences
3 ABSTRACTION Admittedly, and contrary to the above claim that epistemic logic needs to be augmented with adequate bridgeprinciples, the theorems of these logical systems are often defended by interpreting them as models of the knowledge or belief only idealised agents have, or as capturing norms for what it means for agents to be rational (for a critical assessment, see Stalnaker (1991)). Yet, this is not sufficient to avoid the slippery slope ...

GENERAL ASPECTS ABOUT STOCHASTIC THERMODYNAMICS: STOCHASTIC IMPEDANCE AND THERMODYNAMICS OF BROWNIAN PARTICLES. (R-11130) Hasselt University

Theory lab, University of Sao Paulo
This PhD project aims at studying distinct innovative and relevant aspects about stochastic thermodynamics. In the first work package, we consider the use of entropy production as a tool for characterizing phase transitions. Although promising, this study still requires further studies, including an extension for systems with different symmetries and properties and for the analysis of other quantities. We intend to verify/establish whether phase ...
