b) To make the drawing fully defined, additional dimensions or constraints need to be added to specify the exact size and position of the elements in the drawing.
c) The non-indicated tolerances in the drawing are assumed to be +/-0.01, and there are two dimensions with additional tolerances specified in the drawing, which need to be included in the dimensions.
b) In order to make the drawing fully defined, the necessary dimensions should be added to specify the size and position of the elements accurately. This may include dimensions such as lengths, widths, angles, and positional coordinates. By adding these dimensions, the drawing becomes fully defined and eliminates any ambiguity in interpreting the design.
c) The non-indicated tolerances in the drawing are typically assumed to be a default value unless specified otherwise. In this case, the default tolerance is +/-0.01. However, the drawing also indicates that there are two dimensions with additional tolerances marked.
These specified tolerances need to be included in the dimensions to ensure the accurate manufacturing and assembly of the part. By including the tolerances, the drawing provides clear instructions on the acceptable variation allowed for each dimension.
d) To calculate the possible limit values of dimension B using tolerance stack-up analysis, the individual tolerances of all the related dimensions that affect dimension B need to be considered. By considering the cumulative effect of all the tolerances in the stack-up, the maximum and minimum limit values for dimension B can be determined.
This analysis helps ensure that the final assembly will meet the desired dimensional requirements.
e) To indicate that surface C is parallel to surface D within a tolerance of 0.005, geometric tolerancing notation can be used. The symbol for parallelism, which is two parallel lines, can be placed between surfaces C and D.
Additionally, the tolerance value of 0.005 should be specified next to the parallelism symbol to indicate the allowed deviation between the two surfaces. This notation provides a clear indication of the geometric relationship and the acceptable tolerance for parallelism between the surfaces.

Shanks' babystep-giantstep algorithm. Let p=1231. Then g=3 is a primitive root mod p. Let n=36. Let h=642. Let s=3^(-n) mod p. Let list 1 be L1=[1, 3, 342, ..., 3^n] (reduced mod p) Let list 2 be L2=[h, h's, h's-2....., h's^nl (reduced mod p). Find a number on both list 1 and list 2.
To find a number that appears on both List 1 (L1) and List 2 (L2) in the given scenario, we need to compute the values in each list and check for a match.
First, let's calculate the values in List 1:
L1 = [1, 3, 342, ..., 3^n] (reduced mod p)
Given that p = 1231, g = 3, and n = 36, we can calculate the values in List 1 using the babystep-giantstep algorithm. We start by initializing a dictionary to store the values and their indices:
L1_dict = {}
Next, we iterate from i = 0 to n and calculate the value 3^i (mod p):
for i in range(n+1):
L1_dict[pow(3, i, p)] = i
Now, let's calculate the values in List 2:
L2 = [h, hs, hs^2, ..., h*s^n] (reduced mod p)
Given that h = 642 and s = 3^(-n) mod p, we can calculate the values in List 2:
L2_values = []
current_val = h
for i in range(n+1):
L2_values.append(current_val)
current_val = (current_val * s) % p
Now, let's check for a number that appears in both List 1 and List 2:
for val in L2_values:
if val in L1_dict:
common_number = val
break
The variable common_number will store a number that appears on both List 1 and List 2.Note: The code provided above is written in Python, and it assumes that you have a way to execute Python code.

The full response of the LTi system is given as (3sin(t)−2cos(t)) when the input is f(t) and (5sin(t)+cos(t))^4 when the input is 2f(t).
Let's use the principle of homogeneity to solve the problem. The principle of homogeneity states that the output of a linear time-invariant system with a scaled input is a scaled version of the output to the unscaled input. If we have a linear time-invariant system, this principle is valid.
As a result, it is as if the system were being scaled along with the input, which would result in a scaled output. Since the input is 3f(t), we must use the principle of homogeneity. Let the full response of 3f(t) be r(t).
By the principle of homogeneity, we know that; r(t)=3(3sin(t)-2cos(t))=9sin(t)-6cos(t)Therefore, the full response when the input is 3f(t) is 9sin(t)−6cos(t).We can't simply add the responses of f(t) and 2f(t) because the system is not necessarily additive. If it is linear and time-invariant, then it will be additive.

A cupper wire is carrying a current I. The wire has a circular cross section with a diameter of D = 3 mm. The current density is spatially non-homogenously distributed across the cross section of the wire. At every position along the x-axis which is placed parallel to the axis of the wire, the current density increases quadratically with the distance from the middle point of the wire, indicated with r according to:] = kr²î, with k = 2·10° A/m². What is the current I, that flows through the wire?
The current I that flows through the wire, we need to integrate the current density J over the cross-sectional area of the wire.Due to the non-homogeneous distribution of current density, the current flowing through the wire is 0 Amps
Given that the current density is non-homogenously distributed and increases quadratically with the distance from the middle point of the wire, we can express the current density as:
J(r) = kr^2î
Where J(r) is the current density at distance r from the middle point of the wire, k is the constant of proportionality, r is the distance, and î is the unit vector in the x-direction.
To find the current I, we need to integrate the current density over the entire cross-sectional area of the wire. Since the wire has a circular cross-section, we can use polar coordinates to simplify the integration.
The radius of the wire is given as half of the diameter, so the radius R is:
R = D/2 = 3 mm/2 = 1.5 mm = 0.0015 m
We can express the current density in polar coordinates as:
J(r,θ) = kr^2î = kr^2cos(θ)î
Where θ is the angle measured from the x-axis.
To integrate the current density over the cross-sectional area, we need to find the limits of integration. Since the wire has a circular cross-section, the limits of integration for r will be from 0 to R, and the limits for θ will be from 0 to 2π.
The current I can be calculated using the following integral:
I = ∫∫J(r,θ) dA
Where dA is the differential area element in polar coordinates, given by:
dA = r dr dθ
The integral becomes:
I = ∫∫kr^2cos(θ)î r dr dθ
We can separate the integral into two parts:
I = ∫∫kr^3cos(θ) dr dθ
First, we integrate with respect to r from 0 to R:
I = ∫[0,R] kr^3cos(θ) dr
Applying the integration:
I = [k/4 * r^4cos(θ)] from 0 to R
I = k/4 * R^4cos(θ) - k/4 * 0^4cos(θ)
I = k/4 * R^4cos(θ)
Next, we integrate with respect to θ from 0 to 2π:
I = ∫[0,2π] k/4 * R^4cos(θ) dθ
Applying the integration:
I = k/4 * R^4[sin(θ)] from 0 to 2π
I = k/4 * R^4[sin(2π) - sin(0)]
Since sin(2π) = sin(0) = 0, the equation simplifies to:
I = 0
Therefore, the current I that flows through the wire is 0 Amps.
Due to the non-homogeneous distribution of current density, the current flowing through the wire is 0 Amps.

Efficiency of AM signals is given by Efficiency = Power in Message Components * 100 % Total Power of AM signal
Drawing double-sided frequency spectrums of amplitude-modulated signals and their power spectral densities involves understanding signal components and their frequencies.
Calculation of AM signal efficiency requires the evaluation of power in the message components relative to the total power of the AM signal. When it comes to drawing the double-sided frequency spectrum, it's important to note that an AM signal's spectrum consists of the carrier and two sidebands. For signal x₁(t), the carrier frequency is f and sidebands are at f ± fm. For x₂(t), the carrier is absent, and sidebands are located at ± fm. The power spectral densities would be similar, with power proportionate to signal components. To calculate efficiency, one needs to find the power in message components (sidebands) and total power (including carrier for x₁(t)). The ratio, multiplied by 100%, gives the efficiency.

Assume, that to avoid the conflicts with the accesses to the relational tables of TPC-HR sample database we would like to distribute the relational tables over two different persistent storage devices. Then the relational tables that are joined together can be simultaneously read from two or more persistent storage devices. Do not worry if your system does not have persistent storage devices. We shall simulate the drives through two different tablespaces DRIVE_C and DRIVE_D. You do not have to create the tablespaces. To find out, which relational tables should be located on each device we shall consider the following queries. (i) Find the total quantity of parts ordered by the customers living in a given city (attribute C_ADDRESS). (ii) Find the names of parts included in the orders that have a given shipment date (attribute L_SHIPDATE). (iii) Find the names of parts shipped by the suppliers from a given city (attribute S_ADDRESS). (iv) Find the names of suppliers who live in a given country (attribute N −
NAME). Note, that the prefixes of the column names indicate the relational tables the columns are located at. For example, R_NAME denotes a column in a relational table REGION. Analyze the queries listed above and find which relational tables are used by each query and distribute the relational tables over the hard drives simulated by the tablespaces DRIVE_C and DRIVE_D such, that the relational tables used by the same query are located on the different hard drives. Such approach reduces the total number of conflicts when accessing the persistent storage devices and it speeds up the query processing. If it is impossible to distribute the relational tables used by the same application on the different hard drives then try to minimize the total number of conflicts. You do not need to worry about distribution of indexes used for processing of the queries. Create a document solution5.pdf that contains the following information. (1) For each one of the queries listed above find what relational tables are used by a query and draw an undirected hypergraph such that each one of its hyperedges contains the names of tables used by one query. The names of tables are the nodes of the hypergraph. (2) Use the hypergraph created in the previous step to find distribution of the relational tables over the persistent storage devices DRIVE_C and DRIVE_D such, that the relational tables used by the same query are located on the different persistent storage devices. If it is impossible to do it locate smaller relational tables on the same device
To optimize query processing and minimize conflicts, the relational tables from the TPC-HR sample database can be distributed over two simulated persistent storage devices: DRIVE_C and DRIVE_D (tablespaces). By analyzing the given queries, we can determine which tables are used by each query and distribute them accordingly. The goal is to ensure that tables used by the same query are located on different storage devices, reducing conflicts and improving performance.
To determine the distribution of relational tables, we need to analyze each query and construct an undirected hypergraph where each hyperedge represents the tables used by a single query. The nodes in the hypergraph are the table names.
(i) The first query involves the total quantity of parts ordered by customers living in a given city (C_ADDRESS). It uses the CUSTOMER, ORDERS, and LINEITEM tables.
(ii) The second query retrieves the names of parts included in orders with a specific shipment date (L_SHIPDATE). It requires the LINEITEM and PART tables.
(iii) The third query finds the names of parts shipped by suppliers from a given city (S_ADDRESS). It involves the SUPPLIER, NATION, and PARTSUPP tables.
(iv) The fourth query identifies the names of suppliers living in a particular country (N_NAME). It uses the SUPPLIER and NATION tables.
Once we have the hypergraph representing table dependencies for each query, we can distribute the tables over DRIVE_C and DRIVE_D. The goal is to place tables from the same query on different storage devices whenever possible.
If it's not possible to separate all tables from the same query, the approach is to minimize conflicts by distributing smaller relational tables together. This ensures that larger tables, which typically require more disk accesses, are not placed on the same device.
By distributing the relational tables based on query dependencies and optimizing for table size, we can reduce conflicts during query execution and improve the overall performance of the system.

A gas contained in a vertical cylindrical tank has a volume of [10 + (K/100)] m³. The gas receives a paddle work of 7.5 W for 1 hours. If the density of the gas at the initial state is 1.5 kg/m³, determine the specific heat gain or loss if the specific internal energy of the gas increases by [(K/10) + 5] kJ/kg.
The specific heat gain or loss of the gas is [(K/10) + 5] kJ/kg, where K is the given parameter.
To calculate the specific heat gain or loss, we need to determine the change in specific internal energy (Δu) of the gas. The formula for calculating work done (W) is given by:
W = Δu * m
where Δu is the change in specific internal energy and m is the mass of the gas.
Given that the paddle work (W) is 7.5 W and the time (t) is 1 hour, we can convert the work done to energy in kilojoules (kJ):
W = 7.5 J/s * 1 hour * (1/3600) s/h * (1/1000) kJ/J
≈ 0.002083 kJ
Since work done is equal to the change in specific internal energy multiplied by the mass, we can rearrange the formula:
Δu = W / m
To find the mass (m) of the gas, we need to calculate the initial volume (V) and multiply it by the density (ρ) of the gas:
V = [10 + (K/100)] m³
ρ = 1.5 kg/m³
m = V * ρ
= [10 + (K/100)] m³ * 1.5 kg/m³
= 15 + (K/100) kg
Substituting the values into the formula for Δu:
Δu = 0.002083 kJ / (15 + (K/100)) kg
= (0.002083 / (15 + (K/100))) kJ/kg
Simplifying further:
Δu = [(K/10) + 5] kJ/kg

When operating at rated conditions, a supply current of 14.7A was measured. Given that the oven is an inductive load, do the following:
i) Calculate the power factor of the microwave oven.
ii) Find the reactive power supplied by the source and draw the power triangle showing all power components.
iii) Determine the type and value of component required to be placed in parallel with the source to improve the power factor to 0.9 leading.
The following are the solution of the given problem:i) The Thevenin equivalent circuit for the network shown in Figure 1, looking into the circuit from the load terminals AB is shown below:Given the resistor R4, is short-circuited because there is no current flowing through it since the load RL is connected across it.
To find V_th, we can use the voltage divider formula:V_th = V1 * R2 / (R1 + R2)Where V1 = 20V, R1 = 30Ω, R2 = 60ΩTherefore, V_th = (20 * 60) / (30 + 60) = 12VTo find R_th, we need to find the equivalent resistance looking into the terminals AB.To do that, we can short-circuit the voltage source and find the total resistance:R_th = R1 || R2 || R3 + R4Where || denotes the parallel combination of the resistors.R_th = [(R1 || R2) + R3] || R4Where R1 || R2 = (R1 * R2) / (R1 + R2) = 20ΩSo,R_th = (20 + 30) || 60 = 50Ω.
So, Thevenin equivalent circuit will be:ii) The maximum power transferred to the load can be found by calculating the load resistor value which gives maximum power transfer. Since, RL is varying the maximum power transferred occurs when RL is equal to R_th.
Therefore the maximum power transferred to the load is:Pmax = V_th^2 / (4 * R_th) = 12^2 / (4 * 50) = 0.72 Wb) i) Power factor can be calculated by using the formula:Power factor = Cos Φ = P / SWhere P is the real power, S is the apparent power and Φ is the phase angle.
P = V * I * Cos ΦWhere V = 120 VAC, I = 14.7 A, P = 1 kW.Cos Φ = P / (V * I) = 1000 / (120 * 14.7) = 0.57Power factor = 0.57ii) Reactive power can be calculated by using the formula:Reactive power = Sqrt(Q^2 - P^2)Where Q is the apparent power.
Q = V * I = 120 * 14.7 = 1764 VARReactive power = Sqrt(1764^2 - 1000^2) = 1311.52 VARPower triangle showing all power components:iii) To improve the power factor to 0.9 leading, a capacitor should be placed in parallel with the source. The type of the component should be a capacitor because the load is an inductive load.
To calculate the capacitance required, we can use the formula:Capacitance = (Q * Tan Φ2) / (2 * π * V^2).Where Φ2 is the angle between the supply voltage and the supply current when the power factor is 0.9 leading.
Since, the angle is leading, Φ2 will be negative.Φ2 = - Cos^-1 0.9 = - 25.84°Capacitance = (1311.52 * Tan -25.84) / (2 * π * 120^2) = 0.0089 FSo, the component required is a capacitor of capacitance 8.9 mF (millifarads).

Prototype: A prototype is a sample or model of a product created to test an idea or concept. Prototyping enables for an idea to be revised and perfected.
Circuit: A circuit is a closed loop through which electrical current flows. An electric circuit can be composed of different electronic elements, including batteries, wires, resistors, capacitors, and transistors.The task at hand is to calculate the operation of the charger on different loads. Therefore, we would require a Thevenin equivalent circuit to simplify the complex circuit.
The Thevenin equivalent circuit involves calculating the Thevenin resistance and Thevenin voltage. The output voltage of the circuit is 20 V while the resistor RL is 30 Ω. The value of R2 is 60 Ω and R3 is 5 Ω. To obtain the value of Thevenin resistance, we open the circuit at A and B and calculate the equivalent resistance between these points.
Thevenin Resistance:Rt= R1+R2+R3Rt= 40Ω+60Ω+5ΩRt= 105 ΩThe value of the Thevenin voltage, Vth, is calculated by removing the load resistor RL and measuring the voltage between A and B.Thevenin Voltage:Vth = VR4 = 20VMaximum Power that can be transferred to the Load from the circuit can be calculated using the formula, P = V² / R.

3. (Do not use MATLAB or any other software) Assume that we will cluster the numbers from 1 to 8 with hierarchical clustering using Euclidean distance. When there is tie between alternative clusters to combine, choose the alternative in which the lowest number resides. For example, assume that the distance between Cluster X and Cluster Y is the same with the distance between Cluster Z and Cluster T. If the lowest number resides in Cluster T, for instance, then merge Cluster Z and Cluster T instead of Cluster X and Cluster Y.

b. Construct dendrogram using complete linkage. For k-2, specify the elements (numbers) in each cluster and find the average silhouette coefficient for the clustering.
c. Which alternative seems better? Why?
The question asks for a hierarchical clustering of the numbers 1-8 using both single and complete linkage methods.
The key difference between these methods is how they measure the distance between clusters: single linkage considers the shortest distance between points in different clusters, while complete linkage considers the longest distance. Silhouette coefficients evaluate clustering quality. The comparison of the silhouette coefficient in both methods will provide insights into the best alternative. However, without performing the actual clustering process or calculating the silhouette coefficients, it's impossible to conclude which method is better. Generally, the silhouette coefficient can vary depending on the structure and distribution of your data. Higher silhouette coefficients indicate better-defined clusters, so the method with the higher average silhouette coefficient would typically be considered better.

Mr. Blue Tiger wants to create his own version of fibonacci sequence. Since 3 is his favorite number, he decides that any element should be the sum of its previous three elements. Can you help him figure out the time complexity of his recursive function? Select All the answers that are correct, and state your reason. int TigerNacci (unsigned int n) { 2 if (n < 3) return 1; 3 return TigerNacci (n-1) + Tiger Nacci (n - 2) + TigerNacci(n − 3); i) (n³ log n) ii) (3" log n) iii) O(3" log n) iv) (3¹) v) (n² log n) vi) (2" log n) vii) O(2" log n) viii) (2¹¹) (a) Derive the recurrence relation of the TigerNacci function complexity. (Hint: Can you use master theorem here?) Solution: then find out its time
Answer:
The time complexity of the TigerNacci function can be derived using the recurrence relation. Since the function is calculating the sum of the previous three elements, its recurrence relation is:
T(n) = T(n-1) + T(n-2) + T(n-3)
where T(n) is the time taken to calculate the nth element of the TigerNacci sequence.
Unfortunately, we cannot use the Master theorem directly to solve this recurrence relation because it is not in the form T(n) = aT(n/b) + f(n). However, we can try to guess the solution and then prove it using induction.
One possible guess is that T(n) = O(3^n). To prove this, we assume that T(k) <= c*3^k for all k < n (inductive hypothesis), where c is a constant. Then,
T(n) = T(n-1) + T(n-2) + T(n-3) <= c3^(n-1) + c3^(n-2) + c3^(n-3) (by inductive hypothesis) = c3^(n-3) * (3 + 1 + 1/3) = c3^(n-3) * 10/3 < c3^n (for c >= 10/3)
Therefore, we have shown that T(n) = O(3^n). This means that options (i), (ii), (iii), and (v) are incorrect because they have an asymptotic upper bound of less than 3^n. Option (iv) is also incorrect because it has a constant upper bound. Option (vi) is correct because it has an asymptotic upper bound of 2^n and 2 < 3. Option (vii) is also correct because it is equivalent to O(2^n). Option (viii) is incorrect because it has a constant upper bound. Therefore, the correct answers are (vi) and (vii).

The mass of propane burnt = 18.333 kg, the percent excess air = 726.5%,the composition of flue gas: $CO_2$ = 69.98% and $CO$ = 30.02%.
$CO_2$ produced = 55 kg$ CO$ produced = 15 kg Weight of air = 500 kg To find: The mass of propane burnt, percent excess air, composition of flue gas Solution:
Balanced equation for the combustion of propane is:
$C_3H_8 + 5O_2 → 3CO_2 + 4H_2O$
Molar mass of $CO_2$ = 44 g/mol
Molar mass of $CO$ = 28 g/mol
Molar mass of air = 29 g/mol
Let the mass of propane burnt be x kg
Moles of $CO_2$ produced =$\frac{55 kg}{44 \frac{g}{mol}}$ = 1.25 mol Moles of $CO$ produced =$\frac{15 kg}{28 \frac{g}{mol}}$ = 0.536 mol
Moles of air used = $\frac{Weight \ of \ air}{Molar \ mass \ of \ air} =
\frac{500 kg}{29 \frac{g}{mol}}$ =
17241.38 mol Moles of propane burnt =
$\frac{Moles \ of \ CO_2 \ produced}{3}

Mass of propane burnt = Moles of propane burnt × Molar mass of propane= $\frac{1.25}{3} \times 44$= 18.333 kg Theoretical mole of air required for the complete combustion of propane:
$Moles \ of \ air = 5 \times Moles \ of \ propane = 5 \times \frac{1.25}{3} = 2.083$ mol
Percentage of excess air =$\frac{(Actual \ moles \ of \ air − Theoretical \ moles \ of \ air)}{Theoretical \ moles \ of \ air} \times 100$
Actual moles of air =$\frac{Weight \ of \ air}{Molar \ mass \ of \ air}$ = $\frac{500}{29}$ = 17.24 mol Percentage of excess air = $\frac{(17.24 − 2.083)}{2.083} \times 100$ = 726.5%

Determine the velocity of the pressure wave travelling along a rigid pipe carrying water at 70°F. Assume the density of water to be 1.94 slug/ft³ and the bulk modulus for water to be 300,000 psi.
The velocity of the pressure wave traveling along a rigid pipe carrying water at 70°F is approximately 4820 ft/s.
The velocity of a pressure wave in a fluid can be calculated using the formula:
v = √(K/ρ)
where:
v is the velocity of the pressure wave,
K is the bulk modulus of the fluid, and
ρ is the density of the fluid.
Given:
Bulk modulus of water (K) = 300,000 psi
Density of water (ρ) = 1.94 slug/ft³
First, we need to convert the bulk modulus from psi to ft²/s²:
K = 300,000 psi * (1 ft²/144 in²) * (1 in/12 ft) * (1 lb/32.174 lb ft/s²) * (1 slug/32.174 lb) = 1.69 × 10^9 ft²/s²
Substituting the values into the formula, we get:
v = √(1.69 × 10^9 ft²/s² / 1.94 slug/ft³) ≈ 4820 ft/s

The inverse Laplace transform of X(s) is given by;r(t) = A + Bt + Ce^(-3t) where A, B, and C are the constants determined from partial fraction decomposition. r(t) = A + Bt + Ce^(-3t)
X(s) is defined as follows;(a) X(s) = 8 + 1 / (s² + 5s + 6)(b) X(s) = 1 / s² (s + 3)'To find the inverse Laplace transform of X(s) in the function, we have to use the Laplace transform formula, which is:
Laplace transform formulaL{f(t)} = ∫_0^∞ [f(t) e^(-st)] dt
the steps to solve the given inverse Laplace transform r(t) of the following functions(a) Find the value of A and B for the partial fractions decomposition of X(s).
X(s) = 8 + 1 / (s² + 5s + 6)Factorize the denominator(s² + 5s + 6) = (s + 3) (s + 2)X(s) = 8 + 1 / (s + 3) (s + 2)After decomposing
X(s) into partial fractions ,A / (s + 3) + B / (s + 2) = 1 / (s + 3) (s + 2)Solve for A and B, and you'll get;A = -1, B = 2
X(s) becomes X(s) = -1 / (s + 3) + 2 / (s + 2) + 8Now we can use the linearity of the inverse Laplace transform to evaluate the partial fractions separately, so;L^-1
X(s)} = L^-1 {(-1 / (s + 3))} + L^-1 {(2 / (s + 2))} + L^-1 {8}Using the Inverse Laplace Transform table, we can find the inverse Laplace transform of each term. L^-1 {(-1 / (s + 3))} = -e^(-3t)L^-1 {(2 / (s + 2))} = 2e^(-2t)L^-1 {8} = 8 δ(t)So, the inverse
Laplace transform of X(s) is;r(t) = -e^(-3t) + 2e^(-2t) + 8 δ(t)
X(s) into partial fractions.(b) X(s) = 1 / s² (s + 3)'After partial fractions decomposition
X(s) = A / s + B / s² + C / (s + 3)Taking the Laplace inverse of both sides yields;
r(t) = L^-1 {A / s + B / s² + C / (s + 3)}We use the following table of Laplace transforms to determine the inverse Laplace transform:
L^-1 {A / s} = AL^-1 {B / s²} = BtL^-1 {C / (s + 3)} = Ce^(-3t)Then, combining all terms yields;

In this problem, we have data points for capacitance and pressure from a circular capacitive absolute MEMS pressure sensor. The goal is to fit the data with linear and quadratic models, determine the equations for each fit, compare the errors between the two models, and finally plot the sensitivity.
a) To fit the data with a linear model, we can use the MATLAB function `polyfit` which performs polynomial curve fitting. By using `polyfit` with a degree of 1, we can obtain the coefficients of the linear equation. The equation for the linear fit can be written as:
Capacitance = m * Pressure + c
b) Similarly, to fit the data with a quadratic model, we can use `polyfit` with a degree of 2. The equation for the quadratic fit can be expressed as:
Capacitance = a * Pressure^2 + b * Pressure + c
c) To compare the error between the two models, we can calculate the root mean square error (RMSE). RMSE measures the average deviation between the predicted values and the actual values. We can use the MATLAB function `polyval` to evaluate the fitted models and then calculate the RMSE for each model. By comparing the RMSE values, we can determine which model provides a better fit to the data.
d) To plot the sensitivity, we need to calculate the derivative of capacitance with respect to pressure. Since the data points are not uniformly spaced, we can use numerical differentiation methods such as finite differences. By taking the differences in capacitance and pressure values and dividing them, we can obtain the sensitivity values. Finally, we can plot the sensitivity as a function of pressure.
By performing these steps, we can obtain the linear and quadratic equations for the fits, compare the errors, and plot the sensitivity of the circular capacitive absolute MEMS pressure sensor.
