The climate of the British Isles is said to be both temperate and maritime‚ discuss. The British Isles located at 54◦N has historically had very unstable and hard to predict weather patterns due its location where five significantly different air masses converge and with influences from the Sub-polar Jet stream and North Atlantic Drift. Along with the additional complication of global warming potentially causing more extreme weather‚ meteorologists have been unable to agree on whether the UK has

There are many uses for sound in the world today. Performers can take advantage from a better understanding of sound‚ architects needs to understand sound to design effective auditoriums‚ and many new types of technology apply sound recognition. Another use of sound is in the area of science called Nondestructive testing‚ or NDT. Ultrasonic testing (UT) has been practiced for many decades. Initial rapid developments in instrumentation encouraged by the technological advances from the 1950’s continue

X-ray Powder Diffraction Analysis: Principles‚ Instrumentation and Applications M.S.Pandian Department of Earth Sciences‚ Pondicherry University‚ Puducherry-605014 Introduction X-ray powder diffraction analysis (XRD) is perhaps the most widely used X-ray based analytical techniques for characterizing materials. As the name suggests‚ the sample is usually in a powdery form‚ consisting of fine grains of crystalline material to be studied. The term ’powder’ really means that the crytalline domains

1 Unit – 4 Engineering Physics OPTICS Dr. V.P.N. Padmanaban M.Sc.‚ Ph.D.‚ Associate Professor 1. Interference Interference of light waves is a superposition phenomenon. This phenomenon was first described by Thomas Young in 1801. It provided strong evidence for the wave theory of light. In Young’s interference experiment‚ an incident monochromatic light is diffracted by a slit in the first screen‚ which then acts as a point source of light that emits semicircular wavefronts. It is

as for industrial applications. The primary design is obtained on the basis of Euler’s equation for turbomachinery. The design parameters such as head‚ discharge‚ speed‚ number of blades can be changed by sliders. Other parameters‚ e. g. blade angle can be manipulated by interaction in VR using 3D interaction devices. Since Euler’s equation is relatively simple the geometrical shape can be calculated online. Therefore many sets of parameters can be investigated and optimized in a short time
