Explain how you would use your equations to simulate a specific Turing machine by a register machine whose program encodes the quintuplet description. To what extent does this support Turing's Thesis? [Explicit program for a register machine is not required.] [8 marks] 8 Computer Graphics and Image Processing Describe an algorithm for performing scan conversion of a set of 3D polygons, including details of clipping, projection, and the underlying 2D polygon scan conversion algorithm. You may assume that you are given the colour of each polygon and that no lighting calculations are required. Please state any additional assumptions that you need to make. Ray tracing is not an acceptable answer to this question. [20 marks] Describe the design of a discrete occasion test system. What is the head

information structure included? [5 marks]

(c) A queueing network is described by a bunch of visit counts, Vi

, furthermore, per-visit

administration prerequisites, Si

, for every one of N gadgets. Infer upper limits on the

framework throughput (I) when the heap is exceptionally low and (ii) as the heap tends to

limitlessness. [5 marks]

(d) In what circumstances may the limits be especially uncertain? What can be

done to build more tight limits for the framework throughput?

(a) What is an information reserve and how can it contrast from a guidance store?

[4 marks]

(b) What factual properties of memory access do reserves exploit to convey

further developed execution? [4 marks]

(b) Routing calculations can be either interface state or distance-vector. Characterize these two

terms and make sense of the compromises between them. [6 marks]

(c) You are expected to plan a geography revelation convention for an organization of

exchanging hubs interconnected by joins. There are n hubs, l connections, the

greatest level of any hub is k and there is a way between any two hubs of

not more than d bounces. All connections are bi-directional.

Every hub has a remarkable identifier of four bytes which it knows.

(I) Describe a convention for a hub to find out about its nearby neighbors.

You ought to indicate the arrangement of your messages and the size of any message

fields. [4 marks]

(ii) Using the qualities of the organization portrayed above, plan a convention

for disseminating this data across the organization. It would be ideal for you to determine

the configuration of your messages and the size of any message fields

This question connects with double requirement fulfillment issues (CSPs). A CSP has

a set X = {x1, . . . , xn} of factors, each having a space Di = {v1, . . . , vni

} of

values. What's more, a CSP has a set C = {C1, . . . , Cm} of limitations, each relating

to a subset of X and determining the permissible mixes of tasks to the

factors in that subset.

(a) Give an overall meaning of an answer for a CSP. [1 mark]

(b) Given a parallel CSP, characterize how it affects a coordinated curve xi xj between

factors xi and xj to be circular segment steady. [2 marks] (b) (d.i)(b.ii) (ii.i) Write function counts x t that counts the number of times that x occurs as a label in t, but without first converting t to a list. You are designing and are about to launch a mobile phone app which will seek

to understand the emotional condition of the user, using multiple inputs such as

motion sensing, facial expression recognition, voice stress measurement and the

analysis of entered text. Its declared purpose is to enable services to interact

more empathically with users. You propose to monetize it by serving ads at

times when the user is more likely to buy. (by means of calls to work lex()) and giving as result an

theoretical language structure tree relating to. Briefly describe the calling mechanisms just mentioned and discuss why most modern programming languages provide only call by value. [8 marks] (c) Discuss the reasons why languages such as Fortran, Algol and PL/I designed in 1950s and 1960s are less widely used than languages designed in the last 20 years. [6 marks] 3 [TURN OVER CST.2004.3.4 5 Operating Systems II (a) What problem do real-time scheduling algorithms try to solve? [2 marks] (b) Describe one static priority and one dynamic priority real-time scheduling algorithm. You should discuss the issue of admission control, and comment on the data structures that an implementation would need to maintain and on how these would be used to make scheduling decisions.are a data structure protected by a mutual exclusion lock. (i) What scheduling problem could arise here?
