Abstract. Tie-rods are simple structural elements that have been commonly used throughout the centuries to improve stability of old masonry buildings. Measuring dynamic vibrations such can give important information on performance variation with time if proper system models be calibrated taking into account all relevant sources uncertainties. This paper poses and solves inverse problem quantify...

Abstract In this article, a new method for processing trajectory parameter tests of flying targets with the geometric center screen as response time detector is proposed. The superiority over conventional uniform thickness treatment shown through error and data analysis yaw angle, pitch speed. relative distance between test track real shows accuracy method. obvious statistical rules can be foun...

Roughly 20 years ago Valentino Braitenberg published a book on vehicles—a treatment of the amazingly complex behavior of a variety of very simple machines (Braitenberg 1984). This approach was inspired by the “law of uphill analysis and downhill invention.” Accordingly it is easier to design a mechanism to do something from scratch than to figure out just how nature has contrived to do it. Alth...

OBJECTIVE Chest wall vibrations are commonly used techniques that remain largely unquantified. In order to understand their effects, it is essential to measure the forces applied and their repeatability over time. This study investigated the repeatability of vibrations within and between test occasions. DESIGN Test-retest repeatability study. PARTICIPANTS Eight physiotherapists applied vibr...
