Strain-based analysis on the influence of local undercut geometry on fatigue crack initiation life

Alain Nussbaumer, Heikki Tapani Remes, Abinab Niraula

The local undercut defects at the weld toe provide a potential initiation site for fatigue cracks and significantly impact the structure's fatigue strength. The influence of continuous undercut depth on fatigue performance is widely studied, but the resear ...

Study of Potential Factors and their Interaction in Dielectric Elastomer based Cell Stretcher

Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Florian Fernand Hartmann, Simon Holzer, Fatma Öz

Dielectric elastomer actuators (DEAs) offer a high degree of stretchability along with biocompatibility, making them valuable for biomedical applications. However, in order to effectively control the desired strain response of the DEA, it is crucial to ide ...

A Unified Experiment Design Approach for Cyclic and Acyclic Causal Models

Negar Kiyavash, Ehsan Mokhtarian, Saber Salehkaleybar

We study experiment design for unique identification of the causal graph of a system where the graph may contain cycles. The presence of cycles in the structure introduces major challenges for experiment design as, unlike acyclic graphs, learning the skele ...

Discretization Uncertainties of Flow and Fatigue Damage Simulations of a Reversible Francis Pump-Turbine at Off-Design Operation in Turbine Mode

Drazen Dujic, Daniel Biner, Philippe Alexandre Bontemps

In the framework of the XFLEX HYDRO H2020 European Project, a 5 MW reversible Francis pump-turbine prototype, equipped with an industrial full size frequency converter, is investigated to demonstrate enhanced grid regulation capacities of variable speed hy ...

Prediction of the reaction forces of spiral-groove gas journal bearings by artificial neural network regression models

Jürg Alexander Schiffmann, Elia Iseli

This paper presents neural network regression models for predicting the nonlinear static and linearized dynamic reaction forces of spiral grooved gas journal bearings. The partial differential equations (PDEs) are sampled, based on a full factorial and ran ...

Study and characterization of silicon metal alloys systems for the reactive infiltration process of ceramic matrix composites

Manoj Kondibhau Naikade

Silicon infiltrated silicon carbide (SiSiC) is one of the most promising and economical non-oxide ceramic matrix composites for high-temperature structural applications. In recent years infiltration by Si-alloys instead of pure Si has become popular to avo ...

Optimization of a Py-GC/MS method for silicone -based lubricants analysis

Christophe Roussel, Céline Burnier

Condom evidence can be analysed using several analytical techniques, such as FTIR, MALDI-MS or DART-TOF-MS, but the only one that was used on real samples for transfer and persistence studies in the context of sexual assault or rape cases was Py-GC/MS. How ...

A meta-analysis reveals temperature, dose, life stage, and taxonomy influence host susceptibility to a fungal parasite

Suzanne Marie Young

Complex ecological relationships, such as host-parasite interactions, are often modeled with laboratory experiments. However, some experimental laboratory conditions, such as temperature or infection dose, are regularly chosen based on convenience or conve ...

How to improve the sensitivity of coplanar electrodes and micro channel design in electrical impedance flow cytometry: a study

Philippe Renaud, Harald Van Lintel, Jonathan Bastien Cottet

This paper describes a comprehensive analysis of the geometrical parameters in uencing the sensitivity of a coplanar elec- trode layout for electrical impedance ow cytometry. The designs presented in this work have been simulated, fabricated, and tested. 3 ...

Copper-catalyzed methylative difunctionalization of alkenes

Qian Wang, Jieping Zhu, Xu Bao, Minh Tu Ha, Takayuki Yokoe

Trifluoromethylative difunctionalization and hydrofunctionalization of unactivated alkenes have been developed into powerful synthetic methodologies. On the other hand, methylative difunctionalization of olefins remains an unexplored research field. We rep ...
