You have determined the genetic linkage of seven point mutants (r1, r2, r3, r4, r5, r6, and r7). Luckily for you, the map order of the point mutants corresponds to their name, i.e., point mutant r2 is located between point mutants r1 and r3, etc. You wish to locate the deletion mutants r11, r12, and r13 onto this linkage map. To this end, you conduct pair-wise crosses between the deletion mutants and the point mutants to determine if r+ recombinants...

Consider a system with eight resources currently allocated as follows: Resource Allocated to Process R1 P4 R2 P1 R3 P5 R4 P7 R5 P2 R6 P8 R7 P3 R8 P6 The following sequence of additional resource requests is then processed. (Let REQ(A,B) denote process A's request for resource B.) REQ(P4, R2) REQ(P3, R6) REQ(P2, R1) REQ(P7, R7) REQ(P6, R1) REQ(P5, R7) The above sequence of requests do not cause a deadlock. Verify this fact by constructing a resource-allocation graph involving...

1.1. Let R be the counterclockwise rotation by 90 degrees. Vectors r1=[3,3] and r2=[−2,3] are not perpendicular. The inverse U of the matrix M=[r1,r2] has columns perpendicular to r2 and r1, so it must be of the form U=[x⋅R(r2),y⋅R(r1)]^T for some scalars x and y. Find y^−1. 1.2. Vectors r1=[1,1] and r2=[−5,5] are perpendicular. The inverse U of the matrix M=[r1,r2] has columns perpendicular to r2 and r1, so it must be of the form U=[x⋅r1,y⋅r2]^T for some scalars x...
