The SUMMA Platform Prototype

Hervé Bourlard, Andrei Popescu-Belis, Philip Neil Garner, Nikolaos Pappas, Sibo Tong, Yang Wang, Ahmed Ali, Steve Renals, Lesly Sadiht Miculicich Werlen, Marco Damonte

We present the first prototype of the SUMMA Platform: an integrated platform for multilingual media monitoring. The platform contains a rich suite of low-level and high-level natural language processing technologies: automatic speech recognition of broadca ...

Organocatalytic Nucleophilic Addition of Hydrazones to Imines: Synthesis of Enantioenriched Vicinal Diamines

Qian Wang, Jieping Zhu, Yang Wang

In the presence of a catalytic amount of chiral phosphoric acid, nucleophilic addition of N-monosubstituted hydrazones to N-Boc imines affords differentially protected vicinal diamines in the form of b-amino N,N’-dialkyldiazenes in excellent yields with hi ...

Chiral Phosphoric Acid-Catalyzed Enantioselective Formal [3+2] Cycloaddition of Azomethine Imines with Enecarbamates

Qian Wang, Jieping Zhu, Yang Wang

The first catalytic asymmetric inverse electron demand 1,3-dipolar cycloaddition of azomethine imines with enecarbamates has been developed. Isoquinolinefused pyrazolidines containing two or three contiguous stereogenic centers were obtained in high yields ...

A scalable and inexpensive surface-texturization method for advanced transparent front electrodes in microcrystalline and micromorph thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Mathieu Gérard Boccard, Julien Claude Bailat, Yang Wang, Nils Linus Löfgren

As the thin film silicon solar cell technology reaches a pivotal point to keep competing in the photovoltaic industry where crystalline silicon and other technologies currently dominate, it has become an urgent task to revolutionize some of its state-of-th ...

Charge-transfer-induced structural rearrangements at both sides of organic/metal interfaces

Klaus Kern, Yang Wang, Tzu-Chun Tseng, Alexander Langner

Organic/metal interfaces control the performance of many optoelectronic organic devices, including organic light-emitting diodes or field-effect transistors. Using scanning tunnelling microscopy, low-energy electron diffraction, X-ray photoemission spectro ...

Efficient point location via subdivision walking with application to explicit MPC

Colin Neil Jones, Yang Wang

An explicit (or closed-form) solution to Model Predictive Control (MPC) results in a polyhedral subdivision of the state-space when the system and constraints are linear, and the cost is linear or quadratic. Within each region the optimal control law is an ...
