Understanding Computational Costs of Cellular-Level Brain Tissue Simulations Through Analytical Performance Models

Felix Schürmann, Francesco Cremonesi

Computational modeling and simulation have become essential tools in the quest to better understand the brain's makeup and to decipher the causal interrelations of its components. The breadth of biochemical and biophysical processes and structures in the b ...

Simulation of silicon KOH and dry etching methods for micromould fabrication

Laurène Tribolet

The purpose of this project is to investigate the suitability of wet etching methods such as KOH etching for silicon micromoulds fabrication. Those moulds are intended for preceramic polymer (PCP) casting and specific requirements regarding the profile of ...

Output-Capacitance Hysteresis Losses of Field-Effect Transistors

Elison de Nazareth Matioli, Armin Jafari, Luca Nela, Palliyage Srilak Nirmana Perera, Georgios Kampitsis

Resonant-type power converters are supposed to generate zero switching losses during soft-switching operation. In recent research, unexpected switching losses were reported in these converters, which were attributed to a large-signal hysteresis observed in ...

Adaptive HTAP through Elastic Resource Scheduling

Anastasia Ailamaki, Periklis Chrysogelos, Angelos Christos Anadiotis, Syed Mohammad Aunn Raza

Modern Hybrid Transactional/Analytical Processing (HTAP) systems use an integrated data processing engine that performs analytics on fresh data, which are ingested from a transactional engine. HTAP systems typically consider data freshness at design time, ...

Linking simulation and synthesis of nickel oxide hole-selective contacts for silicon heterojunction solar cells

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Angela Nicole Fioretti, Rachel Emma Woods-Robinson

In silicon heterojunction (SHJ) solar cells, one factor limiting efficiency is "parasitic absorption" from amorphous silicon (a-Si) at the front surface. Thus, discovery of a transparent hole-selective contact to replace p-type a-Si is a promising area of ...

Moiré effects produced by superpositions of micro-lens arrays

Thomas Walger

Moiré effects result from the superimposition of repetitive structures. The beauty of these moirés comes from the fact that macroscopic shapes seem to appear from the superposition of layers containing microscopic patterns. In addition, the moirés are dyna ...

Physical Safety in Collisions Between Robots and Pedestrians

Aude Billard, Diego Felipe Paez Granados, David Julian Gonon, Pericle Salvini

The widespread deployment of mobile service robots in public environments and the growing use of autonomy as control modality will increase the exposure to hazards for people simply sharing the robot floor. The need to ensure safety becomes an ethical and ...

Study of Deactivation in Suzuki Reaction of Polymer-Stabilized Pd Nanocatalysts

Lioubov Kiwi

This work is addressed to the phenomenon of catalyst deactivation taking place during the repeated uses in the reaction of Suzuki-Miyaura (S-M) cross-coupling, which is widely applied in industry for C-C bond formation. Ligandless catalysts based on Pd(0) ...
