Thick (>50μm) piezoelectric ceramic films have been deposited directly onto metal substrates as integrated ultrasonic transducer (IUT) receivers to detect the laser generated ultrasound. The film fabrication is based on a sol-gel spray technique. In this investigation IUTs intrinsically acting as bulk longitudinal wave receivers use various mode conversion approaches and serve as longitudinal, ...

Testing is one of the most natural, intuitive and widely used methods to check the quality of software. One of the emerging and promising techniques for test automation is model-based testing. In model based testing, a model of the desired behavior of the implementation under test (IUT) is the starting point for test generation. In addition, this model serves as the oracle for test result analy...

The inevitable rejection of the Big Bang Theory (BBT) will lead to a more enlightened and more logical theory, but what will it be? The BBT will be replaced by the Infinite Universe Theory (IUT). It will produce the greatest revolution in science since Copernicus. A change of this magnitude will not come easily, probably not for decades, but it will come. The outlines of IUT can be seen by exam...

OBJECTIVE The purpose of this study is to report on the pregnancy and neonatal outcome of intrauterine transfusion (IUT) for red blood cell (RBC-)alloimmunization. MATERIAL AND METHODS Retrospective cohort study of all IUT for RBC-alloimmunization in the University Hospital of Leuven, between January 2000 and January 2014. The influence of hydrops, gestational age and technique of transfusion...

Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...

Two stochastic methods for locating global minimum and optimal design parameters of a rectifier power transformer, by Genetic Algorithm (GA) and Simulated Annealing (SA) are presented. A closed form expression for actual phase current waveform of the rectifier transformer is derived and a comparison is made with the approximate waveform normally considered for fixing the transformer rating. The...

This paper describes the development of a novel humanoid robot foot/ankle based on an orientation Parallel Kinematic Mechanism for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotation motions. In order to enable the humanoid robot safely t...

In this paper, we propose a testing method for QoS functions in distributed multi-media systems, where we test whether playback of media objects is correctly implemented or not in a client side program according to the quality designated in advance, and/or whether a time lag between parallel playbacks of multiple media objects is controlled within the specified time interval. In the proposed te...
