The piping system design due to pressure will experience vibrations the excitation force that comes from pump. Excitation occurs changes in fluid flow velocity. In addition, length of pipe and large number bends cross with other installations, cause pipe. vibration analysis should not be underestimated, where it is necessary identify causes placement good support effect obstacles prevent failur...

The main advantage of phase noise meters with photonic (fiber) delay lines is that they do not require high-performance, low-noise reference oscillators. On the other hand, some additional calibrations are required, which subject this paper. First, quadrature must be maintained on mixer by precise adjustment and/or delay. Next, since response proportional to square input test signal, a amplitud...

A DSP-based measurement system dedicated to the vibration analysis on rotating machines was designed and realized. Vibration signals are on-line acquired and processed to obtain a continuos monitoring of the machine status. In case of fault, the system is capable of isolating the fault with a high reliability. The paper describes in detail the approach followed to built up fault and unfault mod...

Orthogonal Frequency Division Multiplexing/Modulation (OFDM) is widely used for symbol level modulationdemodulation in communication systems for a high data rate low distance range applications. OFDM refers to both multiplexing and modulation technique to transmit parallel data using orthogonal carriers in the same or different frequency bands. In this work, DWT-OFDM is modeled which aims to se...

Binaural Cue Coding (BCC) is a method for multichannel spatial rendering based on one down-mixed audio channel and BCC side information. The BCC side information has a low data rate and it is derived from the multichannel encoder input signal. A natural application of BCC is multichannel audio data rate reduction since only a single down-mixed audio channel needs to be transmitted. An alternati...
