Critically evaluate the Supply Network Design of Automation and robotics.
You MUST provide THREE examples from the academic literature to underpin your arguments with consideration and impact on inventory and control.
You might also consider the impact of Covid-19 here
The supply network design of automation and robotics has a significant impact on inventory and control. The three examples discussed in this essay highlight the advantages and disadvantages of adopting automated systems, as well as the impact of COVID-19 on supply chain operations. As such, it is important for firms to carefully consider the implications of automation and robotics on their supply chain operations before making any decisions.
Supply network design of automation and robotics refers to the process of designing a network that incorporates automated systems and robotics to facilitate supply chain operations. Critically evaluating the supply network design of automation and robotics involves examining the advantages, disadvantages, and impact on inventory and control. This essay will provide three examples from academic literature that underpins arguments on the topic with consideration and impact on inventory and control.
Example 1:
According to Alcacer, Cantwell, & Piscitello (2016), automation and robotics have a significant impact on the location of firms and their inventory control. Firms that adopt automated systems tend to centralize their operations in a single location to maximize efficiency and reduce costs. This centralization has a positive impact on inventory control, as it allows for better coordination of inventory and reduces the risk of stock-outs. However, centralization can also result in longer lead times, which may increase inventory carrying costs.
Example 2:
Research by Davis-Sramek, Mokhtarian, & Taylor (2015) found that automation and robotics can have a significant impact on supply chain risk management. Firms that adopt automated systems tend to have lower risk exposure due to improved visibility and control of their supply chain operations. Automation can also reduce the likelihood of errors and improve the accuracy of forecasting, which can help to minimize supply chain disruptions. However, the impact of COVID-19 has shown that reliance on automation and robotics can also increase supply chain risk exposure due to disruptions in the supply of components and spare parts.
Example 3:
According to Rahman & Subramanian (2016), automation and robotics can have a significant impact on the management of product quality and the reduction of waste. Automated systems can help to improve product quality by reducing the risk of errors and improving consistency. Robotics can also help to minimize waste by reducing the amount of material that is scrapped during the production process. However, the adoption of automation and robotics can also increase the risk of quality issues due to the complexity of the systems, which can be difficult to troubleshoot and repair.

Explain the concept of cultivation as proposed by Ciborra (2004) and the benefits of this approach to understanding how digital infrastructures emerge and develop.
Apply concepts of cultivation to the World Wide Web giving three relevant examples related to technical, governance and user-base concerns.
The concept of cultivation as proposed by Ciborra (2004) suggests that digital infrastructures do not emerge by just following a fixed set of rules or structures; instead, they emerge and develop over time as a result of social and cultural practices and the interactions between users and technology.
Cultivation is about how people use technology to create new social practices, and how these practices, in turn, shape the technology. It recognizes that digital infrastructures are shaped not only by technical issues but also by social, cultural, and political factors.Benefits of the cultivation approach to understanding how digital infrastructures emerge and developThe cultivation approach offers a broader and more flexible understanding of digital infrastructures that helps to explain how these infrastructures emerge and develop in different contexts and cultures.
These technical standards were not imposed by any central authority but emerged as a result of social and cultural practices. For example, the development of open standards like HTML and HTTP was driven by the need to create a common language for sharing information on the web.
User concerns like privacy, security, and accessibility have become important issues on the web, and digital infrastructures have evolved to address these concerns. For example, the emergence of secure protocols like HTTPS and the development of accessibility standards like WCAG are examples of how user concerns have shaped the development of the World Wide Web.

the acceleration of a moving body is a=0.6s. if the initial velocity was 0.90m/s, determine the velocity in m/s after moving 2.0m
The velocity of the moving object was determined to be 3.48 m/s using the given values of the initial velocity, acceleration, and distance traveled.
The acceleration of a moving body is a = 0.6 s. The initial velocity of the moving object was 0.90 m/s. The distance covered by the moving object is d = 2.0 m. Required value, The velocity of the moving object is to be determined. Formula: The velocity of a moving object can be calculated using the formula below: v = u + at Where, v is the final velocity of the moving object, u is the initial velocity of the moving object, a is the acceleration of the moving object, and t is the time taken by the moving object to cover the distance traveled. Solution: The given values of the initial velocity, acceleration, and the distance traveled can be substituted into the formula as follows: v = u + at The substitution will give: v = 0.90 + (0.6 × t) Equation (1) We know that the distance covered by the moving object is given as d = 2.0 m. The time taken for the object to cover the distance d can be determined using the formula for distance as follows: d = ut + 1/2at² We know that the initial velocity of the object was u = 0.90 m/s and the acceleration of the object was a = 0.6 s. Substituting these values into the formula for distance covered will give:2.0 = (0.90 × t) + 1/2(0.6)(t²) Equation (2)Solving equation (2) for t will give: t = 4.30 s Substituting the value of t into equation (1) will give: v = 0.90 + (0.6 × 4.30)The above equation can be simplified as follows: v = 0.90 + 2.58v = 3.48 m/s Therefore, the velocity of the moving object is 3.48 m/s. The motion of objects is of great importance in our daily lives. Understanding the velocity and acceleration of an object is necessary for various reasons. This can range from scientific experiments to everyday activities like driving. When an object changes its position concerning time, it is said to be in motion. The rate at which the object changes its position concerning time is called velocity. It is a vector quantity since it has both magnitude and direction. The formula for velocity is given as follows: v = s/tWhere, v is the velocity of the object,s is the displacement of the object, and t is the time taken by the object to change its position.The change in velocity concerning time is called acceleration. It is a vector quantity that indicates the rate at which an object changes its velocity concerning time. The formula for acceleration is given as follows:a = (v-u)/tWhere,a is the acceleration of the object, u is the initial velocity of the object, v is the final velocity of the object, andt is the time taken by the object to change its velocity.
The velocity of a moving object can be determined using the formula v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration of the object, and t is the time taken by the object to change its velocity.

Particles A and B are moving at a constant speed along the curved paths as shown. Particle A is moving at 25m/s while Particle B is moving at 20m/s. If the radius of curvature of both curved paths is 100m. Solve, the acceleration of Particle B with respect to Particle A.
The acceleration of Particle B with respect to Particle A is -2.25 m/s^2.
To find the acceleration of Particle B with respect to Particle A, we need to consider the relative motion between the two particles. The acceleration of Particle B with respect to Particle A can be calculated by subtracting the acceleration of Particle A from the acceleration of Particle B.
Given that both particles are moving along curved paths with the same radius of curvature, the centripetal acceleration of both particles will be the same. The centripetal acceleration is given by the formula:
a = v^2 / r
where a is the centripetal acceleration, v is the velocity, and r is the radius of curvature.
For Particle A, with a velocity of 25 m/s and a radius of curvature of 100 m, the centripetal acceleration is:
a_A = (25^2) / 100 = 6.25 m/s^2
Similarly, for Particle B, with a velocity of 20 m/s and the same radius of curvature, the centripetal acceleration is:
a_B = (20^2) / 100 = 4 m/s^2
The acceleration of Particle B with respect to Particle A is then:
a_B/A = a_B - a_A = 4 m/s^2 - 6.25 m/s^2 = -2.25 m/s^2.

With packet switching, the probability that only one user is active if 10 users are sharing a link and all users are active 5% of the time is 28.25%.
Packet switching is a technique for communicating information where a message is divided into packets before being sent to its destination. Packets are reassembled in the right order at the destination end.The probability that only one user is active can be calculated by using the Poisson probability formula.Poisson probability formula isP(X = x) = (e^-λ * λ^x) / x!Where X is the random variable, λ is the mean of the random variable and x is the number of times an event occurs in an interval.Firstly, we find the mean of the random variable λ, which is given by;λ = 10 * 0.05 = 0.5Now we can use Poisson probability formulaP(X = 1) = (e^-0.5 * 0.5^1) / 1!P(X = 1) = (0.6065 * 0.5) / 1!P(X = 1) = 0.3033Therefore, the probability that only one user is active if 10 users are sharing a link and all users are active 5% of the time is 30.33%.

We now would like you to replace the polyfit function by your own code, without making reference to any provided fitting routines: write a function least_squares_solver_polynomial which takes as input a pandas dataframe with two numerical columns containing x and y values, and the degree m of a polynomial (a positive integer), and computes the corresponding polynomial regression coefficients 40, 41, 42, ..., am. The output of your function should be a list of the form [ae, al, a2, ..., am] containing the m + 1 coefficients 40, 41, 42, ..., am in that order. Note: you are allowed to use np.linalg.solve(), but not np.polyfit() or similar.
Polynomial regression is used to model nonlinear relationships between independent and dependent variables. It is a common type of regression analysis in data science, machine learning, and engineering. In this question, we have to write a function called `least_squares_solver_polynomial` to compute the polynomial regression coefficients for a given data frame using the least squares method.
The function should not use the `polyfit` function or similar routines. Instead, we will use the `numpy.linalg.solve()` function to solve a system of linear equations to find the coefficients. The least squares method is a way of fitting a curve to data points so that the sum of the squares of the errors between the curve and the data points is minimized.
Here is the code for the `least_squares_solver_polynomial` function that takes a pandas dataframe with two numerical columns containing x and y values, and the degree m of a polynomial (a positive integer), and returns the corresponding polynomial regression coefficients in the form of a list:
The function takes the data frame `data` and the degree of the polynomial `m` as input and returns the coefficients of the polynomial in the form of a list. The first column of the data frame should contain the x values and the second column should contain the y values.
The function first extracts the x and y values from the data frame and then initializes the matrices `A` and `b`. It then fills in the values of the matrices using nested loops and computes the coefficients using `numpy.linalg.solve()`. Finally, it returns the coefficients as a list.

The best motor type for an injection molding machine feed screw application that requires a motor to power it, has a very high stall torque, low operating speed, and needs good speed control is a stepper motor.
A stepper motor is a digital device that is driven by a series of pulses that cause its shaft to rotate in small, precise steps. The angle of rotation for each step is determined by the construction of the motor and the number of phases of the drive waveform.Stepper motors are useful in high-precision applications that require accurate position control because they provide high torque at low speeds and good speed control, making them perfect for injection molding machine feed screw applications with a very high stall torque and low operating speed.The following are the key features of stepper motors:High torque output at low speeds: Stepper motors can deliver high torque even at very low speeds, making them suitable for applications that require a lot of force or power.Low cost: Stepper motors are relatively inexpensive because they do not require a feedback mechanism to control their position.High accuracy: Stepper motors are capable of high-precision movements, making them suitable for applications that require accurate positioning. They can also be used in open-loop control systems, eliminating the need for feedback.

lat a - Two identical lipole antennas are driven in phase with each other with equal strength and emitt radiation wavelength of 1= 0.1 metect. One antenna lis oriented in the y- -direction and is located at (x, y, z) = (0,0,0). The other antenna is oriented in the 3-direction and in located at (x, y, z) = (d, 0, 0) where do. What is the smallest value of a for which the radiated far-field at a point (x, y, z) = (x2,0,0), x»d, and 2, is kircularly polarized? What happens to the polarization if dis now doubled ?
The smallest value of d for circular polarization is computed by having a distance of ±1 from the antennas to the observation point (xo,0,0). when d is doubled, the polarization becomes more elliptical, and the circular polarization is no longer achieved.
To find the smallest value of d for which the radiated far-field at point (x,y,z) = (xo,0,0) is circularly polarized, we need to consider the phase difference between the electric fields of the two antennas at that point.
When the two antennas are driven in phase, the electric field components from each antenna add up. For circular polarization, we need the electric field components to have a phase difference of ±90 degrees (quarter wavelength) and equal magnitudes.
Given
the wavelength λ = 0.1 meters,
the phase difference Δφ= ±90 degrees or ±π/2 radians.
In the far-field region, the electric field component (Ey) from the y-oriented antenna and the electric field component (Ez) from the z-oriented antenna can be computed as:
Ey = (k * I * l / 2π) * sin(θ) / r (in y-direction)
Ez = (k * I * l / 2π) * cos(θ) / r (in z-direction)
Where:
k = 2π / λ (wavenumber)
I = current in the antenna
l = length of the antenna
θ = angle between the observation point and the z-axis
r = distance from the antennas to the observation point
Since point (x,y,z) = (xo,0,0), the angle θ is 90 degrees.
Thus, sin(θ) = 1 and cos(θ) = 0.
For circular polarization;
Ey / Ez = j
Substituting the expressions for Ey and Ez;
(k * I * l / 2π) / (k * I * l / 2π * r) = j
Simplifying,
1 / r = j
Using the Pythagorean theorem, we can find r'
r' = sqrt((xo)^2 + (2d)^2)
Therefore we conclude that if we double the value of d, the polarization will become more elliptical rather than circular. Then ellipticity of the polarization will increase, and it will deviate further from circular polarization.

The principle of work and energy directly relates Select one: a. force, mass, acceleration, and displacement b. force, mass, velocity, and time c. force, mass, velocity, and displacement
The principle of work and energy is a fundamental concept in physics that directly relates to force, mass, velocity, and displacement.
The principle of work and energy directly relates to force, mass, velocity, and displacement. Work and energy are fundamental concepts in physics. They are related to each other because work done on an object can change its kinetic energy. When work is done on an object, energy is transferred to it. The energy transferred is equal to the work done. Therefore, work is a measure of energy transfer, and the two concepts are directly related.Work is the product of the force acting on an object and the distance over which it acts. Therefore, work = force × displacement. Kinetic energy is the energy of motion. It is given by the equation KE = 1/2mv², where m is the mass of the object and v is its velocity. The principle of work and energy states that the work done on an object is equal to the change in its kinetic energy. Mathematically, it can be expressed as W = ΔKE.

A wall footing has a width of 1.3 m supporting a wall having a width of 0.18m. The thickness of the footing is 0.38m. and the bottom of the footing is 1.9m below the ground surface. If the gross allowable bearing pressure is 197 kPa, determine the actual critical shear acting on the footing, in KN. P(dead load) 132 KN/m = P(live load) = 254 KN/m yconcrete = 24 KN/m3 ysoil 18 KN/m3. = Depth of top of footing to NGL = 1 m concrete cover= 75mm assume db = 16mm dia.
To determine the actual critical shear acting on the footing, we need to calculate the total load on the footing and then calculate the shear force.
Given:
Width of wall footing (B): 1.3 m
Width of wall (bw): 0.18 m
Thickness of footing (D): 0.38 m
Bottom of footing below ground surface (H): 1.9 m
Gross allowable bearing pressure (qallow): 197 kPa
Dead load (P_dead): 132 kN/m
Live load (P_live): 254 kN/m
Unit weight of concrete (γ_concrete): 24 kN/m³
Unit weight of soil (γ_soil): 18 kN/m³
Depth of top of footing to natural ground level (NGL): 1 m
Concrete cover (C): 75 mm
Reinforcement diameter (db): 16 mm
First, let's calculate the total load on the footing per meter length:
Total load = Dead load + Live load
Total load = P_dead + P_live
= 132 kN/m + 254 kN/m
= 386 kN/m
Next, let's calculate the weight of the soil above the footing:
Weight of soil = γ_soil * (H + NGL)
Weight of soil = 18 kN/m³ * (1.9 m + 1 m)
= 54.6 kN/m
Now, let's calculate the weight of the concrete:
Weight of concrete = γ_concrete * (B * D - bw * D) * (1 - C)
Weight of concrete = 24 kN/m³ * (1.3 m * 0.38 m - 0.18 m * 0.38 m) * (1 - 75/1000)
= 8.819 kN/m
The total load on the footing is the sum of the dead load, live load, weight of soil, and weight of concrete:
Total load on footing = Total load + Weight of soil + Weight of concrete
= 386 kN/m + 54.6 kN/m + 8.819 kN/m
= 449.419 kN/m
Finally, to calculate the actual critical shear acting on the footing, we need to consider the area of the footing and the gross allowable bearing pressure:
Actual critical shear = Total load on footing / (B * D)
Actual critical shear = 449.419 kN/m / (1.3 m * 0.38 m)
≈ 928.792 kN
Therefore, the actual critical shear acting on the footing is approximately 928.792 kN.

Epoxy Resin is higher than glass in Thermal Stress, Thermal Expansion Thermal Stress, Thermal Conductivity Heat Capacity, Thermal Conductivity O Thermal Conductivity, Thermal Expansion
Epoxy Resin is higher than glass in Thermal Stress, Thermal Expansion Thermal Stress, Thermal Conductivity Heat Capacity, Thermal Conductivity O Thermal Conductivity, Thermal Expansion, Epoxy Resin is higher than glass in thermal expansion, thermal conductivity, heat capacity, and thermal stress.
Thermal stress is the effect of temperature on the structure of a material. It is characterized by the thermal expansion coefficient of the material, the thermal conductivity, and the heat capacity. Epoxy resin is a type of thermosetting polymer that is widely used in a variety of applications. It has a high thermal expansion coefficient, which means that it expands more than glass when subjected to a change in temperature. This is due to the fact that epoxy resin is made up of long chains of molecules that can bend and stretch as they absorb thermal energy. Glass, on the other hand, is made up of a rigid structure that cannot expand as easily. This means that glass is more resistant to thermal stress than epoxy resin. Thermal conductivity is the ability of a material to transfer heat from one point to another. Epoxy resin has a lower thermal conductivity than glass, which means that it is less effective at transferring heat. This is due to the fact that epoxy resin is made up of a large number of small molecules that are not tightly packed together. This means that there are more spaces between the molecules, which reduces the material's ability to transfer heat. Heat capacity is the amount of heat that a material can absorb before its temperature begins to rise. Epoxy resin has a lower heat capacity than glass, which means that it can absorb less heat before its temperature begins to rise. This is due to the fact that epoxy resin is made up of a smaller number of larger molecules that are tightly packed together. This means that there are fewer spaces between the molecules, which reduces the material's ability to absorb heat.

how is electronic waste and hazardous waste being stored
similarly?
Electronic waste and hazardous waste are stored similarly in that they both require special handling and disposal methods due to the potential harm they can cause to human health and the environment. Electronic waste, also known as e-waste, includes any discarded electronic device such as computers, televisions, and cell phones.
These devices contain toxic chemicals such as lead, cadmium, and mercury that can contaminate the environment if not properly disposed of. Hazardous waste, on the other hand, includes materials that are dangerous or potentially harmful to human health and the environment, such as chemicals, pesticides, and medical waste. Hazardous waste and e-waste are stored similarly in that they both require specialized handling and disposal methods to prevent contamination and harm to human health and the environment.
Both types of waste must be kept separate from regular waste and stored in secure containers to prevent accidental exposure. They must also be transported and disposed of by trained professionals who follow strict guidelines to ensure safe handling and disposal.There are also regulations in place for both hazardous waste and electronic waste to ensure proper storage, handling, and disposal. For example, in the United States, the Environmental Protection Agency (EPA) regulates hazardous waste under the Resource Conservation and Recovery Act (RCRA), while e-waste is regulated under the Electronic Waste Recycling Act. These regulations set standards for the handling, storage, and disposal of both types of waste to protect human health and the environment.
