Abstract:

If we look at the construction industry, particularly the modular single-family construction industry, we often see that the design stage is distinctly separate from the construction and fabrication stages. This separation has been occurring for some time now, however, there is often a noticeable lack of understanding of the constraints in linking architectural design to modular construction for single-family housing. In addition, no framework exists which seeks to support overcoming these constraints for the architectural design process while simultaneously bringing knowledge of fabrication,

Abstract:

This dissertation describes the development of temperature and pH-responsive interfaces, where the emphasis is placed on tuning the responsivities within a physiological temperature range. This tuning is achieved through the utilization of polymeric building blocks, where each component is specifically synthesized to have a unique responsivity. The assembly of these components onto surfaces permits the fabrication of stimuli-responsive interfaces. In addition, this dissertation explores the use of a self-assembling peptide as a modular building block to modify the interface of hydrogel micropa

Abstract:

Double-sided module exhibits electrical and thermal characteristics that are superior to wire-bonded counterpart. Such structure, however, induces more than twice the thermo-mechanical stress in a single-layer structure. Compressive posts have been developed and integrated into the double-sided module to reduce the stress to a level acceptable by silicon dice. For a 14 mm x 21 mm module carrying 6.6 mm x 6.6 mm die, finite-element simulation suggested an optimal design having four posts located 1 mm from the die; the z-direction stress at the chip was reduced from 17 MPa to 0.6 MPa.<br>Ph.

Un nombre de sujets concernant la microrobotique numérique ont été abordés dans le cadre de cette the` se. Une nouvelle génération du microrobot numérique ”DiMiBot” a e´ te´ proposé ce qui rend le DiMiBot plus précis, plus contrôlable et plus petit. La nouvelle structure est formée de deux modules multistables seulement, ce qui ajoute des fonctionnalités´ s importantes comme l’augmentation du nombre de positions avec une taille plus réduite et la capacité´ de réaliser des trajectoires complexes dans l’espace de travail. Le principe du nouveau module multistable combine les avantages des microa

Abstract:

L’objectif de cette thèse est la fabrication de membranes polymères pouvant être complexées à un textile pour améliorer le confort thermique ressenti. Celles-ci doivent être capables de moduler dynamiquement leurs propriétés optiques dans le moyen infrarouge (MIR) en fonction de leur environnement.La première partie de ce travail présente les notions théoriques liées au confort thermique et mécanismes physiques de transferts hydrique et thermique à travers les membranes textiles. Un état de l’art permet d’identifier les technologies existantes. Il introduit le concept des cristaux photoniques

Abstract:

<p>When the amorphous silicon (a-Si) dangling bonds are bonded to hydrogen the concentration of the dangling bond is decreased. The resulting film is called hydrogenated amorphous silicon (a-Si:H). The reduction in the dangling bonds concentration improves the optoelectrical properties of the film. The improved properties of a-Si:H makes it possible to manufacture electronic devices including a solar cell. A solar cell device based on the hydrogenated amorphous silicon (a-Si:H) was fabricated using the Hot-Wire Chemical Vapour Deposition (HWCVD). When an n-i-p solar cell configuration is grown

Abstract:

Le nitrure de gallium (GaN) constitue le meilleur candidat pour la réalisation de transistors de type HEMT de puissance fonctionnant à haute fréquence. A l’heure actuelle, en raison de la faible disponibilité de substrats GaN, la plupart des dispositifs sont fabriqués par hétéro-épitaxie sur des substrats Si, SiC, ou saphir. Jusqu'à présent, aucun de ces substrats n’a permis la croissance directe de GaN de haute qualité cristalline. Par conséquent, le développement de ces technologies doit faire face à de nombreux défauts (densités de dislocations de l’ordre de 108-1010cm-2) et à des contraint
