If A and B are two fuzzy sets with membership functions $\mu _A (x)=\{0.6,0.5,0.1,0.7,0.8\}$ $\mu_B(x)=\{0.9, 0.2, 0.6, 0.8, 0.5\}$ Then the value of $\mu_{\overline{A \cup B} }(x)$ will be $\{0.9, 0.5, 0.6, 0.8, 0.8\}$ $\{0.6, 0.2, 0.1, 0.7, 0.5 \}$ $\{0.1, 0.5, 0.4, 0.2, 0.2\}$ $\{0.1, 0.5, 0.4, 0.2, 0.3 \}$

If we convert $\exists u \forall v \forall x \exists y (P(f(u), v, x, y) \rightarrow Q(u,v,y))$ to $\forall v \forall x (P(f(a), v, x, g(v,x)) \rightarrow Q(a,v,g(v,x)))$. This process is known as Simplification Unification Skolemization Resolution

An operating system using banker’s algorithm for deadlock avoidance has ten dedicated devices (of same type) and has three processes P1, P2 and P3 with maximum resource requirements of 4, 5 and 8 respectively. There are two states of allocation of devices as follows: State 1 ... State 1 is safe and State 2 is unsafe Both State 1 and State 2 are safe Both State 1 and State 2 are unsafe

Suppose S and Q are two semaphores initialized to 1. P1 and P2 are two processes which are sharing resources. P1 has statements wait(S); wait(Q); critical-section 1; signal(S); signal(Q); P2 has statements wait(Q); wait(S); critical-section 2; signal(Q); signal(S); Their execution may sometimes lead to an undesirable situation called Starvation Race condition Multithreading Deadlock
