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.

Your task is to replace the round robin CPU scheduling scheme you developed in Practical 6 with a priority-based scheduling algorithm. To simplify matters, you can maintain the ori
Explain Wait for Graph a. Use a resource allocation graph to derive a wait-for graph. b. Wait-for graph acquired by making an edge from p 1 to p 2 iff p 1 is waiting for
What are the three main activities of an operating system in regard to secondary-storage management? a) Free-space management. b) Storage allocation. c) Disk scheduling.
Define I/O and CPU Bursts Applications typically to through cycle of CPU bursts and Input/output bursts. Since the CPU sits idle during I/O operations, efficiency is improved
The scheduling technique in which CPU is allocated to the process with least CPU-burst time is known as Shortest job first Scheduling is a scheduling technique in which CPU i
