3. Describe a scenario where driving a bridge circuit with a constant cur- rent source is more advantageous than driving the circuit with a constant voltage source.

PLEASE GIVE BRIEF DEFINITIONS OF:

ElGamal

Asymetric algorithm

symmetric algorithm

Diffe-Hellman key aggrement

How they are related each other and how it is encrypted in bit wise explanations (with the octect rule and ip addresses, and how it was encrypted using those) and how it would be coded as an example.

PLEASE GIVE FULL DEFINITIONS AND EQUATIONS INVOLVED AND GIVE SOME EXPLANATIONS HOW IT IS RELATED IN BIT WISE

Could someone provide me with a guide or example of how to write the report below?

Produce a detailed report on any application of microcontrollers in controller designs for real-life application. Write about the kind of interfaces used for input and output data and also why microcontrollers where used for controller designs. (1200 words)
(Write a report on any implementation of a controller using microcontrollers for real-life application. The report must have details on the application of the controller, implementation of the controller, interfaces used and why microcontrollers are used to implement the controller.)

a) i) The following VHDL code contains erroneous syntax. Re write the code in its corrected format onto your answer sheet. You may assume that din is a 16-bit vector and that the ld, lr and cl inputs are 1-bit wide.

lp: process(clk)
signal reg : std_logic_vector(15 downt
begin
if cl=’1’ then
reg := (others:=’0’);
else
if clk=’1’ and clkevent then
if ld=’1’
reg <= din;
end if;
if lr=’1’ then
reg := reg(14 downto 0) & “0
else
reg := ‘0’ && reg(15 downto
end if;
end if;
end process

Describe, in your own words, the functionality of the circuit
described by the corrected VHDL code from i). Your answer
must explain the purpose of the lr, ld and cl inputs.

Please give me a guideline about the experimental set up on the estimation of lithium ion battery parameters and the state of charge estimation

Please TYPE because a lot of handwriting is diffcult to read. In at least 100 words or more, please discuss the different factors that must be considered when choosing a flow sensor for a system.

1a) Carry out a baseline energy audit to come up with an appliance power matrix of your household
giving the type of appliances, quantity and power rating of appliances that can be powered by a
solar system.
b) Estimate appliance usage times in a calendar day (diurnal) to come up with an appliance time of
use scheduling matrix for your household.
c) Calculate the daily load (kWh) and peak power (kW) required and plot the load profile of your
household.
d) Hence or otherwise design a Stand-alone semi integrated PV system using PV Syst that aims to
meet the daily energy requirements for your home. You may use site dependent detailed losses,
horizon shadings and economic parameters of your choice. Clearly state all assumptions.
e) Use the software HOMER to carry out optimal sizing (based on least cost of energy) of a hybrid
renewable energy system comprising of a solar PV array, a diesel generator, storage battery, inverter
and AC & DC load for your home. NB: Use prevailing country specific economic parameters and
discount rates. Make logical assumptions where necessary.
f) Comment and contrast your results of part d and e

Call a log-space reduction a reduction that uses only O(logn) space in addition to the input itself, and not counting the produced result. In other words, there are three tapes: tape 1 is read-only (the input), tape 2 is read-write (the work tape), and tape 3 is write-only (the output tape). Then we insist that tape 2 use O(logn) space (tape 3 is unrestricted, but remember it is write-only). Such a reduction is denoted ≤L. Show that 3SAT ≤L CLIQUE.

Design a LP FIR filter to meet the following specifications using the window method. Use a Blackman window.

Fs = 25 kHz

Fc = 5.0 kHz (3 dB down)

Attenuation = 80 dB at 7 kHz

Give all the relevant plots (impulse, frequency responses) and the performance of the final filter. Compare this filter to one designed using the optimal method .

Slotted non-persistent CSMA: Use the TWO-state Markov chain we discussed in class

to derive the throughput of non-persistent CSMA when nodes are required to transmit at the beginning of

a time slot, the length of a time slot is one propagation delay, and ideal acknowledgments are sent in 0

seconds over a secondary channel.

1) What is the main element used in modern battery technology, explain? and what makes a good battery?

In VHDL with Xilinx Vivado, design a PWM circuit as described in the Background and Theory section. The central part will be 0 to 9 counter, with an integrated comparator. VHDL supports < and > as comparisons. You will just need to integrate a PWM output into the counter. For simulation, use a 10 kHz clock to the counter, which will result in a 1 kHz PWM signal. Simulate a 0%, 30%, 70% and 100% duty cycle.
