Supposing that one of detectors (at l = l0) of a CT scanner is malfunction, which forever outputs a value of 0, i.e. g(l0, θ) = 0. The malfunctioned detector locates below the object however not in the center of the detector array as illustrated in the figure. The parallel ray geometry is supposed.(1) If the projections are obtained with this CT scanner, display the sinogram for the object employed in Q1. (2) Apply the inverse Radon transform to projections to re-construct the object. Display the re-constructed image.(3) Discuss what types of artifacts are examined in the reconstructed image and what a technician must do to avoid such artifacts?(4) In the inverse Radon transform (that is, ‘iradon’), use a distinct filter (that is, the default filter is Ram-Lak) and dispaly the reconstructed image. Discuss how and why the re-constructed image is enhanced.
Peer: It is a term employed of the Abstract Windowing Toolkit (AWT) to refer to the underlying classes which give the platform-specific implementation of the component classes.
What do you mean by the term set up time and hold time constraints? Explain what do they mean? Which one is vital for estimating the maximum clock frequency of the circuit?
State the term DOM and how does this relate to XML?
Reduce Concurrency: From a model-checking perspective, the searched state space consists of all possible thread-state combinations, which implies that the level of concurrency has the biggest impact on state space size. As a consequence, reducing conc
Write a program that prints out 20 random cards form a standard deck of 52 cards. Make sure the program prints out different sets of cards from one run to the next.

You have a driver as drives a long signal and connect to an input device. On the input device there is either undershoot, overshoots or signal threshold violations, so what can be done to correct such problem?
Conditional operator: It is an operator taking three operands that is, a ternary operator. The conditional operator (?:) is employed in the form bexpr ? expr1 : expr2 Q : What is an Integer What is an Integer : What is an Integer: It is a negative or positive whole number. The primitive types are: short, byte, int and long are utilized to hold integer values in narrower or broader ranges.
