We consider three different hash functions which produce outputs of lengths 64,128 and 160 bit. After how many random inputs do we have a probability of ε =0.5 for a collision? After how many random inputs do we have a probability of ε= 0.9 for a collision? Justify your answer.
Answers
Answer:
To calculate the number of random inputs required for a probability of ε=0.5 or ε=0.9 for a collision in a hash function, we can use the birthday paradox formula, which states that the probability of at least one collision in a set of n randomly chosen values from a set of size m is:
P(n, m) = 1 - (m! / (m^n * (m-n)!))
where ! denotes the factorial operation.
For a hash function producing outputs of lengths 64, 128, and 160 bits, the number of possible outputs are 2^64, 2^128, and 2^160, respectively.
To calculate the number of inputs required for ε=0.5, we need to solve for n in the above equation when P(n, m) = 0.5:
0.5 = 1 - (m! / (m^n * (m-n)!)) 0.5 = m! / (m^n * (m-n)!) (m^n * (m-n)!) = 2m! n ≈ sqrt(2m*ln(2)) (approximation)
Using the approximation formula above, we get:
For 64-bit hash function, n ≈ 2^32 For 128-bit hash function, n ≈ 2^64/2^2 = 2^62 For 160-bit hash function, n ≈ 2^80
So, for ε=0.5, the approximate number of random inputs required for a collision are 2^32 for a 64-bit hash function, 2^62 for a 128-bit hash function, and 2^80 for a 160-bit hash function.
To calculate the number of inputs required for ε=0.9, we need to solve for n in the above equation when P(n, m) = 0.9:
0.9 = 1 - (m! / (m^n * (m-n)!)) 0.1 = m! / (m^n * (m-n)!) (m^n * (m-n)!) = 10m! n ≈ sqrt(10m*ln(10)) (approximation)
Using the approximation formula above, we get:
For 64-bit hash function, n ≈ 2^34 For 128-bit hash function, n ≈ 2^65 For 160-bit hash function, n ≈ 2

• What is Strain? . What is the strain gauge? What is the principle of strain gauge (tension and compression)? • The uses of each type of strain gauge? • Include pictures for reference.
Answers
Strain is a unitless measurement that refers to the amount of deformation of an object as a result of an applied force or stress. The strain gauge is an electrical device that measures strain by detecting changes in electrical resistance. It is made up of a thin metal foil or wire that is bonded to a backing material, such as paper or plastic.
The principle of strain gauge is based on the fact that when a metal conductor is stretched, its resistance increases, and when it is compressed, its resistance decreases. The resistance change is proportional to the amount of strain that the gauge is exposed to. Therefore, by measuring the change in resistance, we can determine the amount of strain that the object has undergone. Strain gauges can be used to measure both tension and compression. When the strain gauge is under tension, the metal foil is stretched, causing it to become longer and thinner. This increases the resistance of the gauge. When the gauge is under compression, the metal foil is compressed, causing it to become shorter and thicker.
This decreases the resistance of the gauge.There are several types of strain gauges, each with its own unique application. Here are a few examples:• Linear strain gauges - used to measure uniaxial strain in one direction.• Rosette strain gauges - used to measure biaxial or triaxial strain in multiple directions.• Weldable strain gauges - designed to be welded directly to a metal surface.• Bolt-on strain gauges - attached to the surface of a bolt or other fastener to measure the strain on the joint.• Strain gauge load cells - used to measure force, weight, or torque.

A refrigerator with a COP of 3.0 removes heat from the refrigerated space at a rate of 10 kW. Determine the rate of power input.
Answers
The rate of power input for this refrigerator is 3.33 kW.
A refrigerator with a COP (Coefficient of Performance) of 3.0 is designed to remove heat from the refrigerated space efficiently. The COP is the ratio of the amount of heat removed from the refrigerated space to the work (power input) done by the refrigerator.
In this case, the heat removal rate is given as 10 kW. To determine the rate of power input, we can use the following formula:
COP = (Heat removal rate) / (Power input)
Rearranging the formula to solve for the power input:
Power input = (Heat removal rate) / COP
By substituting the given values:
Power input = (10 kW) / (3.0)
Power input = 3.33 kW (approx.)
So, the rate of power input for this refrigerator is approximately 3.33 kW. This means that for every 3.33 kW of electrical power supplied to the refrigerator, it is able to remove 10 kW of heat from the refrigerated space. A higher COP indicates a more energy-efficient refrigerator.

Answers
A freewheel diode provides a path for the load current to circulate, thus preventing an inductive voltage spike that could damage the switch immediately after it is turned off is the correct statement to describe the function of a freewheel diode in a switching circuit with a single switch.
A freewheel diode is not a fully controllable switch. It is also not a switch that functions as an uncontrolled switch because its switching state is not only reliant on the voltage applied across it. For an inductive load in a switching circuit, a freewheel diode must be placed in parallel with the inductive load because it provides a path for the load current to circulate.
The freewheel diode has a reverse bias in this configuration, so it does not contribute to the current flow. It will, however, dissipate the energy stored in the inductive load when the switch is turned off.

A milling circuit consists of a primary SAG mill that is in open circuit. This is then followed by 2 secondary ball mills in parallel. The product from the SAG mill is fed to the ball mills, with the product from the ball mills being combined and classified in cyclones. The underflow from the cyclones is recycled, with the overflow forming the feed to the flotation circuit.
a) Draw the circuit, labelling items.
The milling circuit has a feed rate of 1 500 t/hr. Consider 2 size classes, above and below 75 microns. The feed has 25% passing 75 microns and each of the mills breaks 50% of the material in the feed above 75 microns to below 75 microns. The partition number for the particles above 75 microns is 0.75, while that below 75 microns is 0.25.
b) Carry out a mass balance to calculate the mass rate of both size fraction in each stream. What is the feed rate to each of the ball mills? What is the percentage passing 75 microns in the circuit product/flotation feed? This milling circuit’s feed has 80% passing 1 cm and the final feed to the flotation circuit has 80% passing 60 microns.
Answers
The correct answer is a) Here is a diagram of the milling circuit with labels: The product from the SAG mill is fed to the two ball mills in parallel, with the product from the ball mills being combined and classified in cyclones. The underflow from the cyclones is recycled, and the overflow goes to the flotation circuit.
To calculate the mass rate of each size fraction in each stream, we can start with the total feed rate of 1,500 t/hr. Since 25% of the feed is below 75 microns, that means 75% of the feed is above 75 microns. Of that 75%, 50% will be broken down in the SAG mill to below 75 microns, while the remaining 50% will be broken down in the two ball mills in parallel. Therefore: Mass rate of particles above 75 microns in feed = 1,500 x 0.75 = 1,125 t/hr Mass rate of particles below 75 microns in feed = 1,500 x 0.25 = 375 t/hr Mass rate of particles above 75 microns in SAG mill product = 1,125 x 0.5 = 562.5 t/hr Mass rate of particles below 75 microns in SAG mill product = 1,125 x 0.5 + 375 = 937.5 t/hr Mass rate of particles above 75 microns in each ball mill product = 562.5 / 2 = 281.25 t/hr Mass rate of particles below 75 microns in each ball mill product = 375 / 2 = 187.5 t/hr Mass rate of particles above 75 microns in combined ball mill product = 562.5 t/hr Mass rate of particles below 75 microns in combined ball mill product = 375 t/hr + 187.5 t/hr = 562.5 t/hr Mass rate of particles above 75 microns in cyclone overflow = 562.5 t/hr x 0.95 = 534.38 t/hr (assuming a 5% bypass) Mass rate of particles below 75 microns in cyclone overflow = 562.5 t/hr x 0.05 + 375 t/hr x 0.95 = 393.75 t/hr (assuming a 5% bypass) Mass rate of particles above 75 microns in cyclone underflow/recycle = 562.5 t/hr x 0.05 = 28.13 t/hr Mass rate of particles below 75 microns in cyclone underflow/recycle = 375 t/hr x 0.05 + 187.5 t/hr = 205.63 t/hr To calculate the feed rate to each ball mill, we can use the mass rate of particles below 75 microns in the combined ball mill product, which is 562.5 t/hr. Since there are two ball mills in parallel, the feed rate to each ball mill will be: Feed rate to each ball mill = 562.5 t/hr / 2 = 281.25 t/hr Finally, to calculate the percentage passing 75 microns in the circuit product.

To address resistance to changes, it is crucial to establish open and transparent communication channels with all stakeholders involved in the project. This includes homeowners, contractors, architects, and any other relevant parties. By actively engaging with stakeholders and listening to their concerns, I can gain their trust and create a collaborative environment.
Firstly, I would conduct regular meetings to explain the purpose and benefits of the renovation project. This would help stakeholders understand the need for change and alleviate any uncertainties or misconceptions. Clear and concise communication is key to ensuring everyone is on the same page.
Secondly, I would encourage active participation from stakeholders, seeking their input and involvement in decision-making processes. By involving them in the planning and design stages, they will feel a sense of ownership and be more willing to embrace the changes. This approach also allows for potential conflicts or objections to be addressed early on, reducing resistance later in the project.
Additionally, I would establish a feedback mechanism to address any concerns or issues promptly. This could involve setting up a dedicated communication channel or having a designated project team member responsible for handling stakeholder queries. Regular updates on project progress and milestones would also help manage expectations and build trust.

A square aluminum plate 5 mm thick and 150 mm on a side is heated while vertically suspended in quiescent air at 75°c. determine the average heat transfer coefficient for the plate when its temperature is 15°c by two methods: using results from the similarity solution to the boundary layer equations, and using results from an empirical correlation.
Answers
By using the boundary layer equation, the average heat transfer coefficient for the plate is equal to 4.87 W/m²k.
Given the following data:
Surface temperature = 15°C
Bulk temperature = 75°C
Side length of plate = 150 mm to m = 0.15 meter.
How to calculate the average heat transfer coefficient.Since we have a quiescent room air and a uniform pole surface temperature, the film temperature is given by:
\(T_f=\frac{T_{s} + T_{\infty} }{2} \\\\T_f=\frac{15 + 75 }{2} \\\\T_f = 45\)
Film temperature = 45°C to K = 273 + 45 = 318 K.
For the coefficient of thermal expansion, we have:
\(\beta =\frac{1}{T_f} \\\\\beta =\frac{1}{318}\)
From table A-9, the properties of air at a pressure of 1 atm and temperature of 45°C are:
Kinematic viscosity, v = \(1.750 \times 10^{-5}\) m²/s.Thermal conductivity, k = 0.02699 W/mk.Thermal diffusivity, α = \(2.416 \times 10^{-5}\) m²/s.Prandtl number, Pr = 0.7241.Next, we would solve for the Rayleigh number to enable us determine the heat transfer coefficient by using the boundary layer equations:
\(R_{aL}=\frac{g\beta \Delta T l^3}{v\alpha } \\\\R_{aL}=\frac{9.8 \;\times \;\frac{1}{318} \;\times \;(75-15) \;\times \;0.15^3 }{1.750 \times 10^{-5}\; \times \;2.416 \times 10^{-5} } \\\\R_{aL}=\frac{9.8\; \times 0.00315 \;\times \;60\; \times\; 0.003375 }{4.228 \times 10^{-10} }\\\\R_{aL}=1.48 \times 10^{7}\)
Also take note, g(Pr) is given by this equation:
\(g(P_r)=\frac{0.75P_r}{[0.609 \;+\;1.221\sqrt{P_r}\; +\;1.238P_r]^\frac{1}{4} } \\\\g(P_r)=\frac{0.75(0.7241)}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[2.5444]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{1.2630 }\)
g(Pr) = 0.430
For GrL, we have:
\(G_{rL}=\frac{R_{aL}}{P_r} \\\\G_{rL}=\frac{1.48 \times 10^7}{0.7241} \\\\G_{rL}=1.99 \times 10^7\)
Since the Rayleigh number is less than 10⁹, the flow is laminar and the condition is given by:
\(N_{uL}=\frac{h_{L}L}{k} = \frac{4}{3} (\frac{G_{rL}}{4} )^\frac{1}{4} g(P_r)\\\\h_{L}=\frac{0.02699}{0.15} \times [\frac{4}{3} \times (\frac{1.99 \times 10^7}{4} )^\frac{1}{4} ]\times 0.430\\\\h_{L}= 0.1799 \times 62.9705 \times 0.430\\\\h_{L}=4.87\;W/m^2k\)
Based on empirical correlation method, the average heat transfer coefficient for the plate is given by this equation:
\(N_{uL}=\frac{h_{L}L}{k} =0.68 + \frac{0.670 R_{aL}^\frac{1}{4}}{[1+(\frac{0.492}{P_r})^\frac{9}{16}]^\frac{4}{19} } \\\\h_{L}=\frac{0.02699}{0.15} \times ( 0.68 + \frac{0.670 (1.48 \times 10^7)^\frac{1}{4}}{[1+(\frac{0.492}{0.7241})^\frac{9}{16}]^\frac{4}{19} })\\\\h_{L}=4.87\;W/m^2k\)

There are two types of check-in counters in use,exclusive and public (or "Shared Use)."Shared Use"systems are changing the way airports operate. Please describe the content of the "Shared Use" system, and talk about the advantages of"Shared Use"system and the possibility of final realization from your experience at the airport.
Answers
Answer:
Exclusive and public check-in counters are the two types of check-in counters used at airports. Exclusive check-in counters are usually used by more luxurious and expensive airlines, while public or "shared use" check-in counters are used by more affordable airlines. These public check-in counters are usually located in the same airport terminal area and can be used by all airlines.
The "shared use" system is changing the way airports operate by allowing passengers to use the same check-in counters for all airlines. With this system, passengers can choose which check-in counters are available and closest to their boarding gate.
The advantage of the "shared use" system is that passengers can choose which check-in counters are available and closest to their boarding gate. In addition, the system also allows passengers to avoid long queues at certain airline check-in counters.
The possibility of the final realization of your experience at the airport depends on many factors such as your arrival time at the airport, the number of other passengers, and the availability of staff and facilities at that airport. However, by using a "shared use" system, you can speed up your check-in process and avoid long queues at selected airline check-in counters.
