What is the difference between laser Doppler velocim etry (LDV) and particle image velocimetry (PIV)

Directions Part 1: Due Thursday at 9pm. Answer the questions below. Dark energy density parameter ₁ 2.5 2.0 1.5 1.0 0.5 0.0 -0.5 -1.0 Gray area: No Big Bang (density of matter could never have been infinite) 0.0 K Expansion is speeding up Expansion is slowing down This model, for which m=1.00, and A=0.00, has been ruled out by observations. Universe expands forever Universe recollapses M Universe is closed Universe is open 0.5 1.0 1.5 2.0 Matter density parameter m 2.5 a. Which areas (H, I, J, K, L, or M) are the accelerating universes? (As opposed to the expansion staying steady or decelerating.) b. Which area (H, I, J, K, L, or M) represents a flat universe with a matter density parameter of 1.0? c. Which area (H, I, J, K, L, or M) represents a universe containing 76% Dark Energy? d. Which area (H, I, J, K, L, or M) represents the universe that Supernova Type la, galaxy cluster, and CMB data results indicate we are in? e. Which area (H, I, J, K, L, or M) represents the universe that…

When waves approach an irregular shoreline, do the waves refract (bend) towards the parts of the coastline that stick out  (headlands/shallower water)?   Or do the waves refract (bend) towards the parts of the coastline that are recessed  (bays/deeper water)?   choose one Waves do not refract (bend) along irregular shorelines. Waves refract (bend) toward bays/deeper water Actually wave refraction (bending) depends on water temperature - not water depth. Waves refract (bend) toward headlands/shallower water.

You can assume that friction is negligible and that the mass of the rods and disk that T attaches to are very small compared to the balls.

You have a telescope that consists of two converging lenses which are placed a distance apart which is approximately equal to the sum of their focal lengths. Focal length 1 is appriximatly 5.5cm and focal length 2 is approximatly 25cm.  The lens closest to the onject should have a resonably long focal length and the eyepiece lens should have a relatively short focal length to get good magnification.   a. draw a scale ray diagram for a telescope using one long and one short focal length lens. b. Estimate how much larger your distance object appears through your telescope and then calculate the angular magnification.

Can the kinematics of a particle can be regarded as the same as the kinematics of a point? Explain

A patient is imaged using a 256 x 256 image matrix on a GC with a rectangular, 40 cm by 55 cm, field of view (FOV). Calculate the dimensions (length and breadth) of each rectangular pixel of the matrix, in mm.

isometric view , needed urgently

a) b) You want to know the temperature of the receiver after 8 hours of night time have passed (in the conditions described in the previous question). What technique would you use to determine this temperature? General lumped capacitance or 1-D transient analysis? Why?
