The constrained geometry of structures : optimization methods for inverse form-finding design
… This dissertation shows how the design of constrained structural systems is better solved by an inverse form-finding process, where the parameters and initial conditions of the direct form-finding process are automatically adjusted to match the design intent. By defining a general framework …

Synthesis of Early Transition Metal Complexes Supported by Pyrrolyl and Indolyl Based Ligands
… stability due to the chelate effect. Frequently, Constrained Geometry Catalysts (CGC) are comprised of early transition metals supported by chelating ligands. The chelating CGC ligands usually contain an η5-dienyl moiety tethered to anionic donor. The pendent donor conventionally is an amide or …

Zweikernkomplexe multifunktioneller Pyrazolatliganden als bimetallische Analoga von N-Chelatkomplexen : Synthese, Koordinationschemie, Eigenschaften
… (sog. Komplexe mit eingeschränkter Geometrie, 'constrained geometry'). Innerhalb der Arbeit gelang die Synthese und die Untersuchung des Koordinationsverhaltens verschiedener neuartiger, präorganisierter Kompartiment-Ligandsysteme. Die strukturellen und physikalisch-chemischen Eigenschaften der …

Incorporation of Polar Comonomers Into High Density Polyethylene With a Cyclopentadienyl-Amido Titanium Catalyst
… purpose of this research was to synthesize the constrained geometry catalyst Ti[(C5Me4)SiMe2(tBuN)]Cl2 (1) with MAO as a cocatalyst for ethylene homopolymerization and copolymerizations with 1-TMSO-alkenes to produce a copolymer with polar functionality. Three 1-alkenols of varying length were …

Low Temperature Solder Demountable Joints for Non-Insulated, High Temperature Superconducting Fusion Magnets
… HTS in a non-insulated coil, a highly adaptable geometry presents itself for the inclusion of hundreds of demountable joints between coil turns. The joints have stringent requirements; they must be low resistance to minimize power dissipation, and to reduce the non-insulated coil radial current …

Shape Estimation under General Reflectance and Transparency
… complex, a pixel's scatter trace has a highly-constrained geometry that reveals the direct surface reflection, and leads to a simple ``Scatter-trace stereo'' algorithm for computing the exterior surface geometry. Finally, we develop a reconstruction system for scenes with reflectance properties …
