Femme fatale-figuur in Tom Lanoye se Monster-trilogie
No full textThe interest of Flemish author Tom Lanoye in the manifestation of evil in female figures finds expression in his drama Mamma Medea (2001) and his Monster-trilogy consisting of the novels Het goddelijke monster (1997), Zwarte tranen (1999) and Boze tongen (2002). This article interrogates Lanoye’s choice of a postmodernist femme fatale, Katrien Deschryver, as the main protagonist in his Monster-trilogy about the demise of the Deschryver family. The trilogy is a critical investigation into the societal malaise in Belgium at the end of the twentieth century after the atrocities of paedophile Marc Dutroux came to light. In Lanoye’s novels the beautiful Katrien, as the catalyst of a series of disasters that bring her once eminent family to ruin, functions as a convenient projection and scapegoat as Belgian society grapples with more pervasive crises that it is still unable to fathom or express adequately. The monstrous figure of the femme fatale, Katrien Deschryver, serves as the concrete manifestation of ongoing tensions in Belgium as a culturally divided country that was created in 1830 as a safeguard to the balance of power in Europe. It is only when she disfigures her face and literally comes to exemplify the monstrous properties that male dominated society invested in her that Katrien is liberated from her function as a projection of both masculine and more general societal insecurity. The article concludes with a discussion of Katrien as a symbol of Belgium as an artificial and therefore “monstrous” construct that threatens to fall apart as a political entity which, at the same time, is also the unsteady seat of European unity
In Flanders' Fields: Postcolonialism, Multiculturalism And The Limits Of Tolerance
No full textIn his Mwana Kitoko series of paintings Luc Tuymans reflects critically on Belgium’s colonial past. The same critical revisionism is also present in the non-fiction and fiction works written by Lieve Joris and in the history books by Daniel Vangroenweghe. In the recently published and widely acclaimed El Negro en ik by Frank Westerman the author provides an eye-opening overview of the racial thinking in Europe during the 19th and 20th century. Lately however, the confrontation of the European with the other has shifted to Europe. In books such as Los by Tom Naegels, De ontelbaren by Elvis Peeters or Fort Europa. Hooglied van versplintering by Tom Lanoye different perspectives on the multicultural society are provided. Simultaneously Europe is also rediscovering and revaluing its roots. A more nuanced picture of Europe’s colonial past is emerging in the exhibition Het geheugen van Congo. De koloniale tijd or in the novelette De trousse by Leo Pleysier

Desenvolupament d'una tècnica de simulació per a predir el comportament vibratori d'un sòl flotant sobre un sòl estructural flexible
No full text[EN] The installation of floating floors is a widely used practice to mitigate airborne and impact noise in
buildings. Floating floors help mitigate impact noise and vibrations to any adjacent room, especially the
room below, by isolating the impact source in the source room. Generally, during the design, both the
floating floor (FF) and structural floor(SF) are considered rigid, which means that the floating floor is
considered as a single mass supported by springs on a rigid support (structural floor). The system is treated
as a single degree of freedom (SDOF) system and the transmissibility curve is used to predict the sound
and vibration reduction performance of the installed floating floor; in such a system the mitigation starts
at frequencies higher than √2 times the resonance frequency. However, in a lot of cases the floating floor
and the structural floor could be flexible, with considerable bending modes influencing the performance
of the floating floor especially at low frequencies, making the SDOF approach to overestimate the system
performance considerably.
This thesis investigates the low frequency performance of a flexible floating floor installed over a flexible
structural floor by using FEM by means of COMSOL Multiphysics. The effect of the thickness of structural
floor on floating floor is studied and the results show that it can affect the isolation performance of the
floating floor due to the contributions of its bending modes.
The stiffness of the bearings(springs) affects the performance of the floating floor as it does for the
simplified SDOF system and is addressed in the thesis. Increasing the stiffness shifts the SDOF mode as
well as some of the bending modes of the floating floor to higher frequencies and vice versa. Increasing
the stiffness negatively affects the performance by decreasing the insertion loss and vice versa, at
frequencies above the SDOF mode.
The negative effects of the bending modes, especially of the floating floor on the performance of the
floating floor system can be avoided by arranging the bearings in a specific combination. Three such
combinations are studied.
The coincidence of bending modes from floating floor and structural floor can result in prominent negative
effects in the performance of the floating floor and hence should be avoided.
A simplified 3-DOF system is also developed, to predict the behavior of the floating floor with results in
close agreements to those from COMSOL. This simplified system can be used to predict the behavior of
the system with three important resonance modes, using MATLAB instead of COMSOL, allowing to save
computational time.[ES] CDM Stravitec, bajo la supervisión de Patrick Carels y Reinhilde Lanoye, y Andreia Pereira (Univ. Coimbra)
La instalación de suelos flotantes es una práctica ampliamente utilizada para mitigar el ruido aéreo y de impacto en los edificios. Los suelos flotantes ayudan a mitigar el ruido de impacto y las vibraciones a cualquier habitación adyacente, especialmente la habitación de abajo, aislando la fuente de impacto en la habitación de origen. Generalmente, durante el diseño, tanto el suelo flotante (FF) como el suelo estructural (SF) se consideran rígidos, lo que significa que el suelo flotante se considera como una masa única soportada por muelles sobre un soporte rígido (suelo estructural). El sistema se trata como un sistema de un solo grado de libertad (SDOF) y la curva de transmisibilidad se utiliza para predecir el rendimiento de reducción del ruido y las vibraciones del suelo flotante instalado; en un sistema de este tipo, la mitigación comienza a frecuencias superiores a √2 veces la frecuencia de resonancia. Sin embargo, en muchos casos el suelo flotante y el suelo estructural podrían ser flexibles, con modos de flexión considerables que influyen en el rendimiento del suelo flotante, especialmente a bajas frecuencias, haciendo que el enfoque SDOF sobrestime considerablemente el rendimiento del sistema.Esta tesis investiga el comportamiento a bajas frecuencias de un suelo flotante flexible instalado sobre un suelo estructural flexible utilizando el MEF mediante COMSOL Multiphysics. Se estudia el efecto del espesor del suelo estructural sobre el suelo flotante y los resultados muestran que puede afectar al comportamiento del aislamiento del suelo flotante debido a las contribuciones de sus modos de flexión.
La rigidez de los cojinetes (muelles) afecta al rendimiento del suelo flotante, al igual que en el caso del sistema SDOF simplificado, y se aborda en la tesis. El aumento de la rigidez desplaza el modo SDOF, así como algunos de los modos de flexión del piso flotante, a frecuencias más altas y viceversa. El aumento de la rigidez afecta negativamente al rendimiento al disminuir la pérdida de inserción y viceversa, a frecuencias superiores al modo SDOF.
Los efectos negativos de los modos de flexión, especialmente del suelo flotante, sobre el rendimiento del sistema de suelo flotante pueden evitarse disponiendo los cojinetes en una combinación específica. Se estudian tres de estas combinaciones. La coincidencia de los modos de flexión del suelo flotante y del suelo estructural puede tener importantes efectos negativos en el rendimiento del suelo flotante, por lo que debe evitarse.También se ha desarrollado un sistema simplificado de 3DOF para predecir el comportamiento del suelo flotante, con resultados muy similares a los de COMSOL. Este sistema simplificado puede utilizarse para predecir el comportamiento del sistema con tres modos de resonancia importantes, utilizando MATLAB en lugar de COMSOL, lo que permite ahorrar tiempo de cálculo.Ullah, N.

Effect of an abdominal aortic aneurysm on wave reflection in the aorta
No full textDespite extensive attention to abdominal aortic aneurysm (AAA) in the biomedical engineering community, its effect on aortic hemodynamics and arterial wave reflection has not been addressed before. We used experimental and numerical methods, relying on a realistic AAA geometry constructed from patient computer tomography scans (CT-scans), to study this issue. Pressure and flow waves were measured and simulated before and after AAA repair, and wave reflections were analyzed using linear wave separation and wave intensity analysis. With AAA, pronounced reflections were present in the pressure and flow waveforms. The reflection coefficient measured experimentally in the upper aorta was negative with AAA (-0.10) versus 0.47 without AAA. Wave intensity analysis confirmed the presence of a backward expansion wave caused by sudden expansion of the aorta; this was absent without AAA. These results were confirmed using a 1-D numerical model. A parameter study using this model demonstrated that dominant factors are diameter and compliance of the aneurysm, with larger diameters and more compliant AAA generating more negative reflections. Finally, a preliminary noninvasive study in three patients before and after AAA repair demonstrated that AAA-repair increased the reflection coefficient. In conclusion, the presence of AAA significantly alters wave reflection and hemodynamics in the aorta, with apparently measurable effects in humans.LHT
