The safety of pipe whip is related issue for nuclear power and chemical plants, where pIpes are often used to transport fluids at high pressure and high temperature. Simulation analysis for empty pipe and liquid filled pipe are conducted in this study. The model was made of simple pipe whip system which enables the missile pipe to hit the target pi

Pipe whip is a safety related issue for nuclear power and chemical plants, where pipes are often used to transport fluids at high pressure and high temperature. Experiment works for empty pipe and liquid filled pipe are needed in this study. The model was made of simple pipe whip system which enables the missile pipe to hit the target pipe at an an

In the present work the bond strength of two friction welded polymers was investigated when the bi-material specimens were subjected to projectile impact at 86 ms-1. Two transparent polymer rods of Polycarbonate(PC) and Polymethylmethacrylate Acrylic(PMMA) were joined together using rotary friction welding. Specimens were cut into two different bat

Pulse Residual Excited Linear Prediction (PRELP) is a variant ofCELP encoding algorithm. The PREP, as its name suggests, instead of codebook, use pulses in codebook. This method reduces the searching time for a matching pulse from the codebook. In this chapter, PRELP algorithm is explained along with the design ofsuch codebookSTATISTICAL TIMEDIVISI

In multiplexing many sources are combined in a common channel to maximise the bandwidth of the system. There can be many components of the STDM such as compressed speech sources at lower rates, voice activity detectors and lost frames reconstruction. This chapter briefly explains all three major components for the under lying multiplexer architectu

In standard Codebook Exited Linear Coding (CELP) the encoding method uses random values for excitation vectors. The excitation is modelled by the codebook. Each time a segment of speech is encoded and an excitation vector is matched to minimise the error between original and encoded signal to maintain quality of speech. This chapter narrates the CE

The Multi-Pulse Residual Excitation (MP-PRE) is a modified version of PRELP. The design of MP-PRE considers that after short term and long term correlations yet some correlation exist over the onset and sudden transitional regions where the energy of the signal is rising. This chapter explains the MP-PRE algorithms ofencoding speech at low bit rate

Discontinuous Transmission (DTX) is a concept used in some mobile standards, mostly in Groupe Special Mobile (GSM) systems. In DTX systems, Voice Activity Detection (VAD) and comfort noise are essential element. The usage of DTX in the systems allo\vs transmissions during activity periods and remains silent during non-activities. This chapter is de

Chemicals can be a great threat to society and to the environment, despite its wide usage III industrial applications. Extra precautions have to be taken into account, considering the increasing numbers of accident cases involving chemical-transp0l1ing tanks. Precautions should be taken especially when transporting chemicals of radioactive nature.
