Amino-functionalised β-diketiminate ligands (N-nacnacs): Synthesis and coordination chemistry with Main Group elements by Huan, D

“…The establishment of a library of germylenes and stannylenes bearing different N-bound aromatic substituents with varying degrees of steric bulk allows for a systematic study of the steric effects of the flanking aryl groups on the overall molecular metrics of these complexes. …”

Scheduling and resource optimization in rail operations : models and algorithms by Birhade, Mahendra Pandharinath

“…Railway resources such as tracks, overhead equipment, locomotives, passenger and freight cars require huge capital investments and long lead time for procurement and installation. …”

Stability improvement and control optimization of isolated two-stage AC-DC-DC converter systems by Feng, Fan

“…The analysis results offer instructive implications to fine-tune the design rules of the DAB converters. Bearing the mind that the impedance model of the DAB converter is closely related to the modulation schemes, the impacts of three typical modulation methods on the DAB impedances are analyzed and compared. …”

Topochemical fluorination of some Ruddlesden-Popper phases by Zhang, R

“…The introduction of a cooperative octahedral tilt around the crystallographic z-axis leads to a local breaking of the inversion symmetry of the host lattice on fluorination, although the global inversion symmetry of the lattice is retained due to an alternation in the z-tilt direction in adjacent perovskite sheets.</p> <p>The substitution of Sr²⁺ with Ca²⁺ cations in YSr₂Mn₂O₇ led to an increasing distortion of the metal-oxide framework, resulting in the formation of an orthorhombic symmetry in space group <em>Pnnm</em> adopted by YSr_0.5Ca_1.5Mn₂O₇. …”

Towards robust sensing and recognition : from statistical learning to transfer learning by Yang, Jianfei

“…Secondly, current domain adaptation methods require careful manual hyper-parameter tuning, which is not realistic for unmanned systems such as smart cars. To stabilize the training of adversarial domain adaptation, Max-margin Domain-Adversarial Training (MDAT) is developed in this thesis to realize stable convergence without cumbersome manuals. …”
