The goal of this challenge is to write a small program that handles the parsing and verification of UDP packets, to
demonstrate a small example of overall design architecture and code aesthetic.
Provided are a few files required for bootstrap as well as example input for testing purposes. Note that a variety of
code inputs will be used to evaluate the efficacy of the program: the example provided should be used as a general
test-case (but should work for any general variation of input).
In the course of solving the challenge you are free to use any library on PyPI, which should be included in a
requirements.txt file at the root of your project structure.
Your submission should be implemented in Python 3.

You are designing the PLC logic for a walk-in freezer at a commercial restaurant. Most of the refrigeration equipment is located on the roof (controller, compressor, condenser) and the rest is located inside the freezer (expansion valve, evaporator). A pair of thermostats inside the freezer send a request for cooling signal and a cooling satisfied signal, respectively. When the controller receives the request for cooling, the compressor is turned on. When it receives the cooling satisfied signal, the compressor is turned off.
Freezer evaporators are prone to developing frost buildup on the cooling coils. Ice insulates the evaporator, preventing the rejection of heat into the refrigerant. This causes the freezer to warm up and will trip the thermostat to request cooling, but little can be delivered under this condition. Running the compressor excessively while the evaporator is jammed with insulating ice can also damage the compressor over time as this causes it to ingest liquid. To combat this issue, the controller includes an electromechanical defrost clock that periodically cuts out the compressor circuit. This evaporator is also equipped with electric defrost, which is an electrical heater that should activate for the duration of the defrost cycle.
This fan motors on the condenser should run whenever the compressor is on. The evaporator fan motors should run whenever the compressor is on or when the defrost cycle is activated.
Write a ladder logic program that satisfies these requirements. The ladder diagram can be prepared by hand or with the software of your choice.
Defining Environmental Health
The term “environment” can be interpreted in many ways, depending on the context and perspective. Start by looking up the term “environment” in several dictionaries. Take note of the differences and similarities of each definition and any examples that might be used to describe the term. Then think about the implications of these definitions on the specific meaning of the term “environmental health.”
In your response, address the following:
Summarize the meanings of the term “environment” (indicate which dictionaries you used) and contrast this with the definition of environment provided in the readings and lectures for this week.
Provide your own perspective on the meaning of the term “environmental health.”
Using Monte Carlo Simulations to create the best schedule for a pharmaceutical manufacturing site
Create a new schedule system where you input any number of orders ie enter ORD001 and press enter then enter ORD002 etc. When all the orders are entered you press the GET BEST SCHEDULE button and the simulation outputs the best schedule for all these orders. I want a very simple window (front end) code containing a box to enter the order numbers and a grey button for the get best schedule button and somewhere you get the output schedule (using Java).
The best schedule will be the schedule with the least amount of unused days. The object is to optimise the use of all machines and people so that the least amount of downtime is created. The only random thing in the whole simulation will be the start date ie the date when each product will start to be manufactured. The end date is the date given in the order table Order_Required_By. Ideally all the products would be produced simultaneously but the contraints of people and machines prevents this happening so the simulation will give the most workable solution to get the products made as quickly as possible. I want to use something like this for the picking random dates for the start date.
import scala.util.Random
import java.time.LocalDate
// val start = LocalDate.of(2020, 1, 20)
// val end = LocalDate.of(2020, 2, 12)
LocalDate.ofEpochDay(Random.between(start.toEpochDay, end.toEpochDay))
// LocalDate = 2020-01-26
Identification of the Final Project Topic
For this week’s assignment:
Identify an environmental or occupational exposure to a chemical or group of chemicals in which you are interestedthe topic for your final project. For ideas about topics, you can consult the following sources:
The textbook
The environmental health topics section of the CDC website
The environmental health topics section of the National Institute of Environmental Health Sciences (NIEHS) website
The toxic substances section of the Environmental Protection Agency’s (EPA’s) website
The case studies in environmental medicine from the Agency for Toxic Substances and Disease Registry (ATSDR) website
The hazards and exposures section and the chemicals section of the National Institute for Occupational Safety and Health’s (NIOSH’s) website. NIOSH is a part of the CDC.
Determine how your chosen exposure affects human populations, i.e., the health problems or disease caused by this chemical or group of chemicals.
Choose a topic that is not overly broad. For example:
Choose one chemical: Lead exposure will make a better topic than exposure to toxic heavy metals, which include lead, mercury, chromium, cadmium, etc. (described in the textbook).
Choose a specific population at risk: This population is exposed either to one chemical or to a closely related group of chemicals, such as pesticide exposure to children in agricultural families or occupational exposure to organic solvents among pregnant women.
Write a 3 to 5-page paper in a Microsoft Word document addressing the following:
Describe the chosen environmental or occupational exposure.
Explain the importance of this exposure problem to human health in terms of both of the following issues:
The extent of exposure, e.g., the estimated number of people exposed
The seriousness of disease or diseases associated with the exposure to the substance or group of substances
Describe the population you will study (e.g., the whole population, individuals living in poverty, children, pregnant women, workers in specific occupations, etc.
Explain why you are interested in the environmental or occupational public health problem you selected and the population you selected.
This is going to lead into the final project
For the final project, you will create an environmental-occupational public health analysis report. Each week, you will complete a portion of the report and will progressively integrate concepts from the course. This project will provide an opportunity for you to learn in-depth about a specific environmental or occupational determinant of public health focusing on the magnitude and significance of the problem, affected populations (potentially disparities), and the current strategies for elimination or reduction of the problem. The week-wise final project assignments are structured as follows:
Week 1: Topic identification
Week 2: Statement of the problem
Week 3: Background information on the problem
Week 4: Landscape and stakeholders
Week 5: Range of options for addressing the problem
Each week, you will write a report, addressing the questions posed in the assignment for that week.
You are expected to submit two files for the assignment:
1-A Summary of Findings Report (Word) that provides summary figures from question 1 and responses to questions 2-4.
2-Completed Workbook (Excel) Tabs 1-3 of the Contract and Sales Commission Workbook (Appendix 1).
Formatting: Font Size (12), and Line Spacing (1 – 1.5).
Tips: You can use Pivot table for quick excel work
Write a code in MatLAB where input message signal is your name and surname: “Name” “Surname”. The signal sampling frequency will be 1 MHz, the carrier frequency will be 100 kHz and the number of samples per bit will be 20. The cut off frequency of the filter will be 25 kHz.
Run the code generated and present the signal forms: the input signal, the modulated signal and the output signal of the demodulator, the transmission channel is an ideal channel without noise.
Your brother-in-law, Representative Howard Hughes, lost his bid for reelection. However, thanks to your efforts, he established himself while in Congress as an astute analyst of the health field and, as a consequence, has taken a position as partner at the prestigious Atlanta investment firm of Keller, Keller, Keller, Keller, and Disher. You have decided to take him up on his offer to join him as a manager in the healthcare division.
The other partners have little insight into healthcare other than receiving care. Your brother-in-law has been asked to give a presentation (narrated PowerPoint) on the current status of the health sector and opportunities for investment.
Your job is to provide him with information on the healthcare industry. Key interest items are in the below questions. To be effective, detail needs to be specific, complete with sufficient depth.
The presentation PowerPoint slides must answer the following questions.
How is the role of government likely to change?
Will government be more or less involved in the health sector?
What impact will increased government involvement have on healthcare as a business opportunity?
Where do you see a potential for growth in the health sector?
What opportunities would make for wise investments (e.g., hospitals, home health, mental health, rehabilitation services, managed care, physician group practice management, etc.)?
Is technology a good investment risk? If yes, what sort or types of technologies are likely to be in great demand, assuming a national shift to an integrated delivery system model and a focus on prevention along with treatment?
Description of criterion
The 1015 slide presentation provides information organized in a logical sequence and it follows acceptable best practices. There is good contrast between font and background on all slides. Slides are enhanced with images and illustrations to help the audience understand the content. The layout is visually pleasing.
Organization and Cohesiveness
The presentation is well organized with the content properly subdivided into sections, and the conclusion includes recommendations, strategies, and solutions. It shows transitions, using appropriate relevant vocabulary, concepts, and theories. Logical flow is maintained throughout the presentation. All slides present one idea and a few supporting facts.
Text and Notes
The text on the slides is used to convey key information. The information displayed is clear and easy to understand
