Interpretation:
Whether ceramic and polymeric materials contain dislocations or not should be determined.
Concept Introduction:
Line imperfections in the perfect crystal lead to the dislocation in the crystals.
Dislocations are types of defects in the crystal. The two basic types of dislocations are edge and screw dislocations. There is also a third type called mixed dislocations.
Edge dislocation is easy to see in a lattice as an extra half-plane of atoms. Since, the defective points are produced due to dislocation in the line this is called a line defect. As compared to the edge dislocation, the screw dislocation is hard to visualize. It also results from shear stress, but the movement of defect line is perpendicular to the stress direction.

- In a simulation experiment on a single lane road, one vehicle is travelling at 18 m/s.After 1.5seconds, the vehicle suddenly accelerates at a rate of 1.5 m/s2 for the next2 seconds and remains0 acceleration then after. Simulate the behavior of subsequent vehicle with an initial speedof16 m/s using GM car following model for the first 3 seconds if the initial distanceheadwayis 20 m. Tabulate the results. Assume headway exponent 1.2, speed exponent1.5, sensitivitycoefficient 0.8, reaction time 0.6 seconds, and update interval of0.3 seconds.arrow_forwardCan you draw the computed panel board (2nd attached pic) like the panel board management (1st attached pic)? ps. not graded, i just want to know what it looks like when it draw.arrow_forwardFORWARD FROM POINT B TO POINT A GIVEN THE FOLLOWING: POINT BN=13,163,463.03'E=3,072,129.30' DIRECTION FROM B TO A (NAZ)=276.07529° DISTANCE FROM B TO A = 10.00'arrow_forward

- Consider the following binary tree method for a tree with keys of type Key, which is an object type. public boolean mystery () { return mystery (root, null, null); private boolean mystery (Node x, Key a, Key b) { } if (x == null) return true;B if (a != null && x.key.compareTo(a) = 0) return false; return mystery (x.left, a, x.key) && mystery (x.right, x.key, b); (a) In plain English, describe the function of mystery (). (This should be a short, clear answer. Zero credit for describing the code line by line!)arrow_forwardThis question considers binary trees using the following node class. You may not assume that the tree has any method or additional fields. class Node { } String key; Node left, right; Node root%; // the root of the tree Recall that the height of a node x is the maximum of the number nodes between x and a null link. By definition, the height of a leaf is 0, and therefore the height of the empty tree is -1. (a) Implement a method height which returns the height of the tree, starting from the root. public int height () {arrow_forwardSuppose C is a class that supports equals, hashCode and compareTo. Objects that are not equals are distinct. Given two arrays a [] and b [], each containing N distinct objects of type C, design two algorithms (with the performance requirements specified below) to determine whether the two arrays contains precisely the same set of values (but possibly in a different order). For each algorithm, give a crisp and concise English description of your algorithm. Your answer will be graded on correctness, efficiency, and clarity. You may use any combination of data structures and algorithms discussed in the course (that is, any standard data structure). You may also describe your own variation. Be specific when identifying any data structure or algorithm that you use ("sorting" and "symbol table" are too vague). Do not give code details use high-level descriptions such as "remove the node from the list". (a) Design an algorithm for the problem whose running time is proportional to N log N in…arrow_forward
