Influence of longitudinal reinforcement layouts on RC wall performance

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso, Raluca-Tereza Constantin

Design recommendations for longitudinal reinforcement layouts of reinforced concrete (RC) walls have been derived from plane section analyses. Such an analysis generally favours wall layouts with boundary elements containing large amounts of vertical reinf ...

Evanescent straight tapered-fiber coupling of ultra-high Q optomechanical micro-resonators in a low-vibration helium-4 exchange-gas cryostat

Tobias Kippenberg, Albert Schliesser

We developed an apparatus to couple a 50-mu m diameter whispering-gallery silica microtoroidal resonator in a helium-4 cryostat using a straight optical tapered-fiber at 1550 nm wavelength. On a top-loading probe specifically adapted for increased mechanic ...

Rock mass assessment and corresponding TBM operation optimization for TBM tunneling at depth - a case study of Jinping II hydropower station

Jian Zhao, Lijun Yin

During TBM tunneling at the great depth, problems such as high in situ stress, groundwater inflow and fractured rock masses are main reasons of the geotechnical risk occurrence in TBM tunneling. Thus it is necessary to modify TBM and optimize TBM operation ...

Drawing Planar Graphs Of Bounded Degree With Few Slopes

János Pach, Balázs Keszegh, Doemoetoer Palvoelgyi

We settle a problem of Dujmovic, Eppstein, Suderman, and Wood by showing that there exists a function f with the property that every planar graph G with maximum degree d admits a drawing with noncrossing straight-line edges, using at most f(d) different sl ...

Laboratory Investigation on Seismic Response of Rock Fractures Filled with Granular Materials

Wei Wu

Filling materials may exist in all scales of rock fractures, not only influencing seismic wave attenuation, but controlling rock mass instability. The objective of this study is to experimentally investigate the seismic response of rock fractures filled wi ...

Distributed real-time dynamic security assessment using intelligent techniques

Maher Kayal, Theodoros Kyriakidis, Karthik Kumar

In real time scenario, transmission (of power) in power systems may not be always ideal i.e. they may be interrupted. As a result, the synchronization among the power generating modules may be lost. Loss of synchronization has a direct effect on the stabil ...

Influence of weak-layer heterogeneity on snow slab avalanche release: application to the evaluation of avalanche release depths

Johan Alexandre Philippe Gaume

The evaluation of avalanche release depths constitutes a great challenge for risk assessment in mountainous areas. This study focuses on slab avalanches, which generally result from the rupture of a weak layer underlying a cohesive slab. We use the finite- ...

Flow during the evening transition over steep Alpine slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau

A field campaign, the Slope Experiment near La Fouly (SELF-2010), was conducted to monitor the evening transition of slope flows on clear-sky days from July to September 2010 in a narrow valley of the Swiss Alps. A steep west-facing slope with inclinations ...

Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) feedstock development and optimization for thermoplastic forming of thin planar and tubular oxygen separation membranes

Stefan Diethelm

This paper presents the processing steps for producing thin planar and tubular oxygen separation membranes by thermoplastic forming of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) with polystyrene (PS) and stearic acid (SA) as binder. The influence of powder conten ...
