Printed transition for SIW horn antennas - Analytical model

Juan Ramon Mosig, Marc Esquius Morote, Benjamin Fuchs

A printed transition is proposed to overcome problems limiting the performances of SIW horn antennas when built in thin substrates (thickness <λ 0/10). An analytical model to analyze its behavior is given along with design guidelines. The development of ...

Flexible polyimide-based force sensor

Martinus Gijs, Jagoda Anna Dobrzynska

We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...

Aligning Supply Chain and Product Portfolios

Ralf Seifert, Jean-Sébastien Tancrez, Kerstin Langenberg

In recent years, it has become widely accepted that optimal supply chain design depends on the type of product the chain is catering to. Moreover, as opposed to carrying one product type only, firms deliver a variety of both functional and innovative produ ...

Multipactor prediction in Multi-carrier Systems

Michael Mattes

This communication reports the status of the activity corresponding to the ESTEC contract ”RF Breakdown in Multicarrier Systems” (19918/06/NL/GLC/RF). The main objective of this activity is to propose alternatives to the 20-gap-crossing rule for multipacto ...

Personalized Modeling for Drug Concentration Prediction Using Support Vector Machine

Giovanni De Micheli, Wenqi You Dubout

Building a personalized model to describe the drug concentration inside the human body for each patient is highly important to the clinical practice and demanding to the modeling tools. Instead of using traditional explicit methods, in this paper we propos ...

Regulatory Uncertainty and Nonmarket Capabilities

Bastian Wolfgang Schwark

In 2005, the Economist Intelligence Unit conducted a survey with Chief Risk Officers worldwide across all industries and asked about the biggest threat to their businesses. Interestingly, regulatory risk ranked first. It dominated all other types of risk, ...

Analytical description for current-induced vortex core displacement

In this article, an analytical model for current-induced vortex core displacement is developed. By using this model, one can solve the equations of motion analytically to determine the effects of the adiabatic and nonadiabatic spin-torque terms. The final ...

50 nm thick AlN film-based piezoelectric cantilevers for gravimetric detection

Luis Guillermo Villanueva Torrijo

Due to low power operation, intrinsic integrability and compatibility with CMOS processing, aluminum nitride (AlN) piezoelectric (PZE) microcantilevers are a very attractive paradigm for resonant gas sensing. In this paper, we theoretically investigate the ...

How the obscuration-zone hypothesis affects fragmentation: Illustration with the cohesive-element method

Jean-François Molinari, Sarah Levy

The problem of fragmentation prediction is at the origin of various analytical models. Among them, we focus on the ones introducing the idea of obscured zones. They assume that when a crack initiates at a defect, a stress release wave propagates away from ...
