Bayesian and non-Bayesian methods for the elimination of high-dimensional nuisance parameters KU Leuven
Empirical economics makes increasing use of panel data. To control for unobserved heterogeneity (e.g., heterogeneity in technology across firms, heterogeneity in preferences across consumers, heterogeneity across teachers and students in matched student-teacher data), a common practice is to introduce agent-specific parameters (e.g., additive fixed effects) into panel data models. Such parameters are high-dimensional nuisance parameters and, ...
Inverse characterization of the orthotropic and viscoelastic material properties of lightweight plates using full field guided wave propagation data KU Leuven
With the advent of the 21st century, climate change-related issues began to play a crucial role in consumer decisions as well as in company objectives. To reduce carbon dioxide emission rates and increase sustainability, companies started to invest more in the development and implementation of advanced materials. Nowadays, lightweight materials such as fiber reinforced polymer laminates and wooden panels offer an alternative for metallic ...
Analysis of time varying relationships in multi-country monetary time series. KU Leuven
The main goal of empirical macroeconomics is to understand the relationships between macroeconomic variables, such as the gross domestic product (GDP), inflation and interest rates. This allows for better macroeconomic predictions and helps macroeconomic policy makers to set a sound fiscal and monetary policy. For example, understanding the effect of the short term interest rate on inflation is essential for a central bank, which is ...
On the Multi-scale Vibroacoustic Behavior of Multi-layer Core Topology Systems KU Leuven
In this last decades, honeycomb sandwich panels have been the subject of intensive researches. Indeed, their high mechanical performances combined to a low stiffness to weight ratio result in a reduced acoustic efficiency. Therefore, many designs are usually proposed to overcome this issue. Besides, different methods are developed to model more complex structures using the periodic structure theory to study the wave propagation allowing to ...
Highly efficient perovskite-based multijunction solar cells and modules KU Leuven
With solar panels costs and prices falling rapidly, the major capital cost is nowadays related to the balance-of-system (BOS), which includes inverters, cables, mechanical supports and other area-related costs. Therefore, the photovoltaics (PV) industry has shifted focus from the panel’s costs themselves to the need for higher power conversion efficiencies in order to reduce the cost per watt peak (Wp) installed. Moreover, there is an ...
Synthesis and processing routes of porous materials from Fe-rich slags KU Leuven
The doctoral dissertation will be a part of the SBO project “Geopolymers and Hybrid Cements for Roads and Tunnels” (GHRANTE). The main goal of the project is “to develop innovative, recyclable inorganic polymers-based materials from residues of the non-ferrous metallurgy”. The goals of within those WPs are: WP1: To develop inorganic polymers containing Ca and/or Fe that incorporates the target residues. WP4: To develop a sound absorptive ...
Increasing the range for chickens in use by mobile houses, combined with the production of short rotation coppice Ghent University
Chickens with free-range access often make limited use of their free-range area; a small part of the flock is usually observed outside at any given time, and those that are outside prefer to stay close to their houses. As a consequence, the claimed welfare benefits of free-range use may not be achieved, and nutrient loads in the soil are very high close to the chicken houses. The low range use may have several reasons, such as fear of a ...
Development of Inorganic Polymers for Near-zero Energy Dwellings KU Leuven
Alkali activation has been emerging as a sustainable technology to produce innovative construction materials. Alkali-activated materials have been extensively investigated, but different levels of scientific understanding and industrial implementation can be found among several subgroups of such materials.
The most widely examined alkali-activated materials are commonly known as geopolymers. The scientific knowledge of their reaction ...
Design of automotive sound packages in the mid-frequency range KU Leuven
The pursuit for green, affordable and comfortable cars has pushed the automobile manufacturers to balance the mass, the cost and the performance of every component. This is notably valid for sound packages, which are key components to the interior noise and vibration performance. Their design for the low- and high-frequency range is well established. However, the design for the mid-frequency range (100-1000 Hz) is more difficult, because of ...
