Your undertaking is to make a straightforward representation of SARS-CoV-2 utilizing just two
natives:
a circle of span 1, and
a chamber of a stature 2, its base of sweep 1, and the primary pivot lined up with OZ,
both focused at the beginning. An illustration of such a representation is displayed in Fig. 1
underneath.

(a) Draw a scene chart for the SARS-CoV-2 model, displayed in Fig. 1, in which the
primary shape is a circle and each spike comprises of a chamber and a circle. Use
the ordered progression of the natives (circle - chamber - circle) with the goal that the whole
article can be vivified by changing the fundamental shape. [4 marks]
(b) Provide change frameworks for every hub of the diagram. You don't have to
give the consequences of the framework duplication. Expect that you have a rundown of
N round organizes (φk, θk), for k = 1, . . . , N, which demonstrate the positions
of the spikes. Utilize the directions as displayed in Fig. 2. The primary body has a
sweep of 1, the chamber of the spike has a length of 0.1, a range of 0.025 and
the circle of the spike has a range of 0.05 with the middle at the foundation of the
chamber. [10 marks]
(c) How would you be able to arbitrarily create the round organizes (φk,θk) of the spikes
so they are (a) equally appropriated over the circle and (b) not bunched
together (at least two spikes are not excessively near one another)? Compose pseudocode
for creating (φk,θk).

These days, watches (like tickers, wristwatches, and so on) have an assortment of capacities.
They give the current time and date as well as they can address you, remind you when it's
time to follow through with something, and give a light in obscurity, in addition to other things. Generally,
the point of interaction for these gadgets, nonetheless, shows the time in one of two fundamental ways: as
a computerized number like 23:40 or through a simple showcase with a few hands
- one to address the hour, one for the minutes, and one for the seconds.
In this inquiry, we request that you plan another watch for your own utilization. This could
be as a wristwatch, a mantelpiece clock, an electronic clock, or some other
sort of watch you extravagant.
(a) Think about the intelligent item you are planning: depict what you need
it to accomplish for you. Compose a rundown of utilitarian and non-practical prerequisites.
[4 marks]
(b) Sketch out an underlying low-constancy model for the watch and create in any event
two unmistakable choices that both meet your arrangement of prerequisites recorded previously.
[8 marks]
(c) Nielsen's heuristics utilized for Heuristic Evaluation are: (1) perceivability of framework
status, (2) match among framework and genuine world, (3) client control and opportunity,
(4) consistency and norms, (5) blunder anticipation, (6) acknowledgment instead of
review, (7) adaptability and proficiency of purpose, (8) tasteful and moderate plan, (9)
help clients perceive and recuperate from mistakes, and (10) help and documentation.
Assess the two low-constancy models utilizing Heuristic Evaluation.

A climate application, whose principle screen is displayed in the figure above, has been made
explicitly for occasion coordinators as essential partners.
(a) Evaluate the gave low-constancy model utilizing Cognitive Walkthrough and
the imagined screens (in the event that you really want to, you might concoct your own
suspicions with respect to the essential partners), for the accompanying undertakings:
(I) (beginning from the fundamental screen) View subtleties of the occasion called Field Day
(ii) (beginning from the primary screen) Add another occasion
[proceeded . . . ]

CST0+CST1.2021.3.9
(iii) (beginning from the principle screen) View definite weather conditions conjecture for Field
Day
(iv) (beginning from the primary screen) Change the units of estimation for the
temperature data gave
(v) (beginning from the principle screen) Modify the volume setting to 150
[14 marks]
(b) Using the result of the CW you have led above, give a rundown of
ideas for re-planning this climate application. [3 marks]
(c) Considering that client focused plan is iterative, how might you go about
gathering one more round of information from the objective client bunch utilizing your discoveries
from the CW? Make sense of which information gathering strategies you would utilize and why

Mr. Kim has decided to open a new bank, JIMB's Bank in Malaysia. As the Senior Network Engineer in JIMB's bank, you are required to prepare a report on the networking infrastructure in the new branch. Figure 1 depicts the general network requirement of the bank, and it contains three major department, which are (i) Sales and Marketing, (ii) Finance and (iii) Technical.
