At 500oC, the diffusion coefficient of Cu in Ni is 1.3 x 10-22 m2/s, and the activation energy for diffusion is 256,000 J/mol. From this information, determine the diffusion coefficient of Cu in Ni at 900 oC. (R = 8.314 J / (mol K)) 0oC = 273 K

A cylindrical specimen of some hypothetical alloy is stressed in compression. If its original and final diameters are 30.00 and 30.04mm respectively, and its final length is 130.00 mm, calculate its original length if the deformation is totally elastic. The elastic and shear moduli for this material are 65.5 and 25.4 GPa respectively.

Many vectors are designed to double in size whenever a new element is inserted into a full vector. This operation may entail allocating a new array that is twice the size of the original, and then copying the original elements into the new array before appending the new element. Use one of the three methods taught in class to show that the push_back () operation of such a vector is amortized O (1).

1. Copy the file Pay. java (see Code Listing 1.1) from the Student CD or as directed by your instructor. 2. Open the file in your Java Integrated Development Environment (IDE) or a text editor as directed by your instructor. Examine the file, and compare it with the detailed version of the pseudocode in step number 3, section 1.6 of the textbook. Notice that the pseudocode does not include every line of code. The program code includes identifier declarations and a statement that is needed to enable Java to read from the keyboard. These are not part of actually completing the task of calculating pay, so they are not included in the pseudocode. The only important difference between the example pseudocode and the Java code is in the calculation. Below is the detailed pseudocode from the example, but without the calculation part. You need to fill in lines that tell in English what the calculation part of Pay. java is doing.

Two wafer sizes are to be compared: a 156-mm wafer with a processable area = 150mm diameter circle and a 312-mm wafer with a processable area = 300mm diameter circle. The IC chips in both cases are square with 10 mm on a side? Assume the cut lines (streets) between chips are of negligible width. What is the percent increase in (a) Wafer diameter, (b) processable wafer area, and (c) number of chips for the larger wafer size?
