Since the measurement of mechanical sealing film thickness and just-lift-off time is very difficult, the sealing film condition monitoring method based on acoustic emission signal is proposed. The mechanical seal acoustic emission signal present obvious characteristics of time-varying nonlinear and pulsating. In this paper, the acoustic emission signal is used to monitor the seal end faces just...

OBJECTIVE To obtain normal M mode (one dimensional) echocardiographic values in a substantial sample of normal infants and children. DESIGN Data were obtained over three years from a single centre in central Europe. PATIENTS 2036 healthy infants and children aged one day to 18 years. METHODS In line with recommendations for standardising measurements from M mode echocardiograms, and using...

This white paper provides a description of ultrasound imaging systems with focus on the signal processing strategies. The different system components are briefly discussed followed by a description of ultrasound related peculiarities that the system needs to handle. The system processing for B-mode imaging can be roughly divided into three components: the front end (that includes transmission, ...

The transposase family of proteins mediate DNA transposition or retroviral DNA integration via multistep phosphoryl transfer reactions. For Tn10 and phage Mu, a single active site of one transposase protomer catalyzes the successive transposition reaction steps. We examined phosphorothioate stereoselectivity at the scissile position for all four reaction steps catalyzed by the Tn10 transposase....

We propose an experimental setup for detecting a Majorana zero mode consisting of a spinless quantum dot coupled to the end of a p-wave superconducting nanowire. The Majorana bound state at the end of the wire strongly influences the conductance through the quantum dot: Driving the wire through the topological phase transition causes a sharp jump in the conductance by a factor of 1/2. In the to...

objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...

We describe an implementation of a deconstructed gauge theory with charged fermions defined on an interval in five dimensional AdS space. The four dimensional slices are Minkowski, and the end slices support four dimensional chiral zero modes. In such a theory, the energy scales warp down as we move along the fifth dimension. If we augment this theory with localized neutral 4dimensional Majoran...

This paper describes a simple yet novel approach to the web-based deployment and evaluation of text locating algorithms. Web-based deployment allows algorithms to be evaluated by end users or researchers, without the need to install the algorithm. This is a major advantage both for the end user, and for the algorithm developer. The end user is protected from lengthy installation procedures, whi...

This paper describes a method of signal process applied on an end effects of Hilbert-Huang transform (HHT) to provide an improvement in the reality of spectrum. The method is based on back-propagation network (BPN). To improve the effect, the end extension of the original signal is obtained by back-propagation network. A full waveform including origin and its extension is decomposed by using em...

Landing gear is a structure that is mounted under the fuselage and helps the aircraft in takeoffs and landings. The most important duty of landing gear is the control of vibration exerted on the system through the shock absorber which is a common component to all the landing gear. Considering the importance of this issue, the necessity of investigating shock absorber with features such as high ...
