For the heat conduction problem, investigate the effects on the numerical solution of the following aspects:
1. non-uniform meshes with re?nement at both ends versus a uniform mesh;
2. fully implicit versus Crank-Nicolson timestepping schemes (compare accuracy and demonstrate any non-physical solution behaviour).For the contaminant transport problem, investigate the effects on the numerical solution of the following aspects:
1. fully implicit versus Crank-Nicolson timestepping schemes (compare accuracy and demonstrate any non-physical solution behaviour);
2. averaging versus upwinding advection schemes (compare accuracy and demonstrate any non-physical solution behaviour). For each investigation, you should compare the numerical solution to the exact solution and document your ?ndings in the report. You will be marked on the relevance and effectiveness of your presented results at investigating the above effects, and on your analysis of your results and how they relate to the theory covered in lectures.

When do we write a page from physical memory back to the disk? In general, caches have two broad types of writing policies. One approach is a write-through cache. In this case,

Explain why SSTF scheduling tends to favor middle cylinders over the innermost and outermost cylinders. The center of the disk is the location having the fewest average distanc
Demand paging With demand paging, a page is called into memory only when a location on that page is actually indexed during run time. With pre-paging, pages other than the one
