The final values of EstimatedRTT, DevRTT, and TimeoutInterval after the five SampleRTT values are obtained are 106.64743457 ms, 16.15257153 ms, and 171.25969469 ms, respectively.

The EstimatedRTT and DevRTT values are computed using the following equations:

EstimatedRTT = (1 - α) * EstimatedRTT + α * SampleRTT

DevRTT = (1 - β) * DevRTT + β * |SampleRTT - EstimatedRTT|

TimeoutInterval = EstimatedRTT + 4 * DevRTT


Given that α = 0.125 and β = 0.25, we can compute the EstimatedRTT and DevRTT after each SampleRTT value is obtained as follows:


After the first SampleRTT value (106 ms):

EstimatedRTT = (1 - 0.125) * 100 + 0.125 * 106 = 100.75 ms

DevRTT = (1 - 0.25) * 5 + 0.25 * |106 - 100.75| = 6.3125 ms

TimeoutInterval = 100.75 + 4 * 6.3125 = 125.8 ms


After the second SampleRTT value (120 ms):

EstimatedRTT = (1 - 0.125) * 100.75 + 0.125 * 120 = 102.90625 ms

DevRTT = (1 - 0.25) * 6.3125 + 0.25 * |120 - 102.90625| = 10.4171875 ms

TimeoutInterval = 102.90625 + 4 * 10.4171875 = 144.569999 ms


After the third SampleRTT value (140 ms):

EstimatedRTT = (1 - 0.125) * 102.90625 + 0.125 * 140 = 107.2934375 ms

DevRTT = (1 - 0.25) * 10.4171875 + 0.25 * |140 - 107.2934375| = 18.362890625 ms

TimeoutInterval = 107.2934375 + 4 * 18.362890625 = 180.74495 ms


After the fourth SampleRTT value (90 ms):

EstimatedRTT = (1 - 0.125) * 107.2934375 + 0.125 * 90 = 105.881640625 ms

DevRTT = (1 - 0.25) * 18.362890625 + 0.25 * |90 - 105.881640625| = 17.205917969 ms

TimeoutInterval = 105.881640625 + 4 * 17.205917969 = 174.70629251 ms


After the fifth SampleRTT value (115 ms):

EstimatedRTT = (1 - 0.125) * 105.881640625 + 0.125 * 115 = 106.64743457 ms

DevRTT = (1 - 0.25) * 17.205917969 + 0.25 * |115 - 106.64743457| = 16.15257153 ms

TimeoutInterval = 106.64743457 + 4 * 16.15257153 = 171.25969469 ms


Therefore, the final values of EstimatedRTT, DevRTT, and TimeoutInterval after the five SampleRTT values are obtained are 106.64743457 ms, 16.15257153 ms, and 171.25969469 ms, respectively.

Here is an implementation of the `RetailItem` class in Python:

class RetailItem:

   def __init__(self, description, units_in_inventory, price):

       self . description = description

       self . units_in_inventory = units_in_inventory

       self . price = price

This class has three attributes: `description`, `units_in_inventory`, and `price`. The `__init__` method is used to initialize these attributes with the values passed as arguments.

Now, to create three `RetailItem` objects and store the data in them, we can write a program like this:

# create three RetailItem objects

item1 = RetailItem (" T-shirt ", 10, 19.99)

item2 = RetailItem (" Jeans ", 5, 39.99)

item3 = RetailItem (" Sneakers ", 7, 79.99)

# print the data for each item

print("Item 1:" , item1. description, item1. units_in_inventory, item1. price)

print("Item 2:" , item2. description, item2. units_in_inventory, item2. price)

print("Item 3:" , item3. description, item3. units_in_inventory, item3. price)

In this program, we first create three `RetailItem` objects named `item1`, `item2`, and `item3`, with different values for their attributes. Then, we print out the data for each item using the print function. The output of this program would look like this (see the attachment):

Item 1: T-shirt 10 19.99

Item 2: Jeans 5 39.99

Item 3: Sneakers 7 79.99

Theme: Developing a Solar-Powered Water Pump for Rural Communities

Goal: The goal of this project is to design and develop a solar-powered water pump that meets the needs of rural communities in developing countries. The product should be cost-effective, efficient, and easy to maintain.

Introduction:

Access to clean and safe water is essential for human survival. In rural areas of developing countries, many communities still lack access to reliable water sources. The lack of water has a significant impact on the health, education, and economic development of these communities. To address this issue, we propose the development of a solar-powered water pump that is both cost-effective and efficient. This essay will detail the steps involved in the concept development process, the types of engineering involved in developing this product, and our conclusion based on the product development lifecycle.

Step 1: Identify Customer Needs

The first step in the concept development process is to identify the customer's needs. For this project, the primary customer is rural communities in developing countries. To identify their needs, we conducted extensive research on the challenges they face in accessing water. Our research showed that the communities need a water pump that is reliable, easy to maintain, and affordable. They also need a water pump that can be powered by renewable energy sources such as solar power.

Step 2: Generate Ideas

The next step is to generate ideas for the product. We brainstormed various ideas based on the customer's needs and the available technology. We identified the most promising idea as a solar-powered water pump that can operate in remote areas without access to electricity.

Step 3: Evaluate and Select Ideas

The third step is to evaluate and select the most promising idea. We evaluated the feasibility of the solar-powered water pump idea by considering the cost of materials, the efficiency of the pump, and the ease of maintenance. We selected the idea because it met all of the customer's needs, was cost-effective, and could be easily maintained.

Step 4: Develop and Test Concepts

The fourth step is to develop and test the concept. We developed a prototype of the solar-powered water pump and tested it in a remote rural community. The pump was able to draw water from a deep well and pump it to a storage tank using only solar power. The pump was also easy to install and maintain.

Step 5: Refine and Finalize Concepts

The fifth step is to refine and finalize the concept. We made some improvements to the prototype based on the feedback we received from the rural community. We added a filter to remove impurities from the water and made the pump more durable to withstand harsh weather conditions.

Types of Engineering:

The development of the solar-powered water pump involved different types of engineering. The mechanical engineering team designed the pump, while the electrical engineering team designed the solar panels and battery system. The civil engineering team designed the storage tank and the plumbing system. All three engineering teams worked together to ensure that the product was efficient, reliable, and easy to maintain.

Conclusion:

In conclusion, the development of a solar-powered water pump is a promising solution to the water crisis faced by rural communities in developing countries. The concept development process allowed us to identify the customer's needs, generate ideas, evaluate and select the most promising idea, develop and test concepts, and refine and finalize the product. By involving different types of engineering, we were able to design a product that is cost-effective, efficient, and easy to maintain. If we followed the product development lifecycle process, we believe that the outcome would be a successful and sustainable product that meets the needs of rural communities.
