The goal of the EU-FP7 project WatERP is to achieve more interoperability of software systems along the water-supply chain. A central element to achieve that is the WatERP Water Data Warehouse which shall act as a central data-exchange platform between different software systems. The WDW shall be able to store and provide sensor, measurement and forecasting data, as well as semantic knowledge a...

The control of a dynamic system with multiple degreesof-freedom (DOF) is far simpler if the system is uncoupled. The property of an uncoupled system can be achieved with careful design of mechanical structures in the case of conventional mechanisms. The study reported in this paper will show via experiment the uncoupling property in a compliant mechanism, which is driven by three PZT actuators....

Most aircraft wings are optimized to produce minimum drag under one particular flying speed, while the flying speed actually varies continuously throughout flight. Although conventional hinged mechanisms can change the wing shape in response to the change in flying speed, the connecting hinges create discontinuities over the wing surface, leading to earlier airflow separation. In this paper, we...

Bistable behavior is desirable for a variety of applications because power is applied only during switching, and the mechanism state remains the same regardless of any power interruptions. The low variability in the stable positions also makes accurate open-loop control of many systems possible, and the precise switching characteristics make them valuable in sensing arrays. In this paper, fully...

This paper concentrates on the application of fuzzy logic based on Taguchi method (FLTM) for multiobjective optimization of the small-length flexural pivot (belongs to link 4) in partially four bar-compliant mechanisms. The input parameters such as the input torque and the crank angle of link 2 were optimized with considerations of the multiple performance measures as angular displacement and s...

A hybrid motion system is defined as a mechanical system that combines a macro motion and a micro motion into one system to achieve a large motion and high resolution with fast response simultaneously. In this paper, a spatial hybrid motion mechanism with 3-DOFs is developed that integrates two types of motion through only one compliant mechanism: a macro motion driven by DC servomotors for lar...

A web site or server is said to be KidCode-compliant when it conforms to one of the KidCode naming conventions for all material that might be considered inappropriate for children. A web client or browser is said to be KidCode-compliant when it blocks access to URL’s that are labelled as inappropriate using the KidCode naming conventions, or when it offers an easy optional mechanism permitting ...

We present and discuss measurements performed with XTPX over the European ATM Pilot. The main characteristic of this wide area ATM network is that the traffic contract is enforced by a Usage Parameter Control (UPC) mechanism. When the ATM traffic is compliant with the traffic contract, XTPX achieves a good utilisation of the link. However, when the ATM traffic is not entirely compliant, the UPC...

Compliant bridge mechanisms are frequently utilized to scale micrometer order motions of piezoelectric actuators to levels suitable for desired applications. Analytical equations have previously been specifically developed for two configurations of bridge mechanisms: parallel and rhombic type. Based on elastic beam theory, a kinematic analysis of compliant bridge mechanisms in general configura...

The present work demonstrates the advancement of evolved topologies of path generating compliant mechanisms by introducing initial population strategy with customized NSGA-II algorithm. The strategy is based on the categorization of design domain of compliant mechanisms that generates initial population of elastic continuum structures. It is anticipated in this paper that this strategy further ...
