Confronted with issues, whose (socioeconomic) causes cannot be resolved through the modification of the built environment, architectural interventions may often inadvertently aid the reproduction of the problems they seek to resolve. In eliminating symptoms of social inequality, alienation and marginalization, architecture can legitimize the social order out of which they arise. In such situations, architects’ attempts to concern themselves with narrowly practical concerns are insufficient even to their own aims, and in order to properly address the issues facing it, architecture must simultaneously operate as a vehicle for social critique and political emancipation. In the work of philosopher Slavoj Žižek, a critical-emancipatory intervention corresponds to an emphasis of a constitutive tension and discord (“the gap”) within what is commonly perceived as a stable, neutral background. Critique strives not to explicitly reveal existing problems. Instead, it reveals an inherent inconsistency within an implicit, ideological fantasy of order and harmony that allows us to naturalize these problems. Consequently, the critical-emancipatory potential of architecture resides not in its programmatic content nor in its representational image, but in its capacity to disrupt the reassuring affective texture of ideology. Critique resides in a formally subtle (concerning architecture in its narrowest definition as an affective structure), yet politically radical shift in how problems of everyday life are interpreted and processed; re-introducing a minimal sense of disquietude that is both critical and emancipatory. The disquietude, that marks an absence of a fantasy of order and harmony, can, paradoxically, only be sustained as a product of a formally (representationally) ordered and harmonious appearance. The critical-emancipatory disquietude is not a compromise of the order and harmony, but rather a reflection of its uncompromisingly egalitarian nature.

Wie die tschechische Historiographie überhaupt, so ist auch die tschechische Musikhistoriographie lange Zeit von Stereotypen beherrscht worden, die mit wissenschaftlicher Objektivität wenig zu tun hatten. Daher ist jeder Blick 'von außen' notwendig und willkommen, weil er uns auf die Klischees, aber auch die Lücken in unserer tschechischen Musikgeschichte nicht nur hinweist, sondern uns auch, wie Helmut Loos es in seinem Artikel 'Religiosität bei Smetana und Dvořák' getan hat, dazu veranlasst, unsere Standpunkte unter neuen Fragestellungen zu überdenken.

1 English abstract: Villa Müller versus Villa Tugendhat - A Comparison of Two Different Restoration Projects of Modernist Buildings. The work compares two successful restorations of interwar Czechoslovak avant-garde buildings realized between 1995 and 2012. At first, the respective histories of both buildings are compared since their creation through two totalitarian regimes up to their restoration. The fates of builders and architects of both villas are also described. From the point of view of historic preservation the work describes the state of both buildings before the commencement of restoration. The errors committed by the original designers are also described here. The methodology of restoration of both villas stemming from the professional points of view and relevant laws governing heritage protection is also treated in detail. The emphasis is given on preparation works preceding the design phase - the historic-structural survey, which, in both cases, was conceived as above-standard. Due to their span, these surveys have marked a key moment in relation to the modern cultural heritage within the Czech context. In the last part of the work links and comparisons are given to similar modern cultural heritage objects abroad. The work also documents the influence these two restorations have had on...

Cette thèse présente une nouvelle extension d’onduleur multiniveaux, appelé ‘Multi Neutral Point’ (MNP). Cet onduleur est déduit des topologies des structures multiniveaux ‘Neutral Point Clamped’ (NPC) et ‘Multi Point Clamped’ (MPC). Les intérêts de cette extension sont: l’absence de diodes de bouclage, la possibilité de disposer de tous les nombres de niveaux, pairs et impairs et possibilité de fonctionner en mode dégradé. Nous avons élaboré une commande rapprochée simple des transistors de puissance, d’abord pour un MNP à 3 niveaux, ensuite pour les nombres de niveaux supérieurs. Nous avons comparé les pertes de puissance d’un onduleur MNP et d’un onduleur NPC. Les pertes de l’onduleur MNP sont largement inférieures à celles de l’onduleur NPC. Dans l’optique de contrôler en courant l’onduleur MNP, une stratégie nouvelle par régulateur PID d’ordre fractionnaire est également développée. Ce contrôle permet de diminuer nettement les erreurs d’amplitude et de phase entre le courant de référence et le courant de charge. La méthode nécessite le réglage des différents paramètres de contrôle en utilisant le principe d'optimisation ‘’multi-objectif’’. Le fonctionnement de l’ensemble convertisseur-contrôle-commande est enfin largement validé par simulation et par expérimentation / This thesis presents a new extension of multilevel inverters, called 'Multi Neutral Point' (MNP). This topology is deduced from Neutral Point Clamped (NPC) and Multi Point Clamped (MPC) structures. The advantage of this extension is twofold: the absence of clamping diodes and the possibility of operating on all the numbers of levels (even and odd). We have developed a simple command; we first present the command strategy for a three levels MNP, then for a five level MNP. We have compared the power losses in the power switches of an MNP and an NPC. The power losses for an MNP are far below those of the NPC inverter. For this inverter model, we have chosen a robust current control by a fractional PID controller. This control strategy can sharply reduce the amplitude and the phase errors between the reference current and the load one. This method requires the setting of various control parameters thanks to the principle of ‘’multiobjective optimization.'' In the end the set of converter-control command is validated by simulation and experimentation; the simulated and experimental results match very well
