Evaluating objective measures of impairment to trunk strength and control for cross-country sit skiing

In Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected by subjectivity. An evidence-based classification is required, in which objective measures of impairment must be identified. The purposes ...

Instability of Thin Concrete Walls with a Single Layer of Reinforcement under Cyclic Loading: Numerical Simulation and Improved Equivalent Boundary Element Model for Assessment

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso, Lisandro Arturo Jimenez Roa

Thin reinforced concrete walls may fail due to out-of-plane instability when subjected to seismic loading. While previous numerical studies on wall instability have focused on the behaviour of members with two layers of vertical reinforcement, this work ad ...

Cheetah-cub-S: Steering of a Quadruped Robot using Trunk Motion

Auke Ijspeert, Peter Eckert, Karl Weinmeister

A reliable concept for steering was realized by in- tegrating a spine-like structure with one DoF into a quadruped robot - Cheetah-cub-S. We increased maneuverability dramat- ically compared to a robot with rigid spine, while keeping controlling effort low ...

Adaptive Query Processing on Raw Data Files

Ioannis Alagiannis

Nowadays, business and scientific applications accumulate data at an increasing pace. This growth of information has already started to outgrow the capabilities of database management systems (DBMS). In a typical DBMS usage scenario, the user should define ...

Buckling of a thin elastic rod inside a horizontal cylindrical constraint

Pedro Miguel Nunes Pereira de Almeida Reis

We present results from an experimental and numerical investigation on the compression, and consequent buckling, of a slender rod constrained inside a horizontal cylinder. An experimental model system is developed to systematically study the sequence of in ...

H2O: A Hands-free Adaptive Store

Anastasia Ailamaki, Ioannis Alagiannis

Modern state-of-the-art database systems are designed around a single data storage layout. This is a fixed decision that drives the whole architectural design of a database system, i.e., row-stores, column-stores. However, none of those choices is a univer ...

Aerodynamic Excitation of a Model Low-Pressure Steam Turbine Stage Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

The diversification of power generation methods within existing power networks has increased the requirement for operational flexibility of plants employing steam turbines. This has led to the situation where steam turbines may operate at very low volume f ...

A new concept of modular kinematics to design ultra-high precision flexure-based robots

Reymond Clavel, Murielle Richard

This work deals with the kinematic conception and the mechanical design of ultra-high precision robots, which are at present costly to develop, both in time and money. The aim of this paper is thus to introduce a new modular concept of kinematics which all ...

Anisotropic 2D Diffusive Expansion of Ultracold Atoms in a Disordered Potential

Jean-Philippe Brantut

We study the horizontal expansion of vertically confined ultracold atoms in the presence of disorder. Vertical confinement allows us to realize a situation with a few coupled harmonic oscillator quantum states. The disordered potential is created by an opt ...

Experimental investigation of prechamber autoignition in a natural gas engine for cogeneration

Daniel Favrat, Stefan Heyne, Michael Meier

A novel ignition concept based on autoignition in an unscavanged prechamber is currently being developed at the Laboratory for Industrial Energy Systems (LENI). On a single cylinder test engine a series of experimental runs (CR=8.5-14, =1-1.6, RPM=1150/150 ...
