Analysis of the Celebrities in Frontal-Profile Wild (CPFW) Dataset

Posted on | by Kelvin

Celebrities in Frontal-Profile Wild (CPFW) dataset contains images of 500 subjects (with 10 frontal images and 4 profile images for each subject). 5000 frontal images were pre-processed using D-lib to crop and align the faces. 37 images had a failure to detect (FTD) case. The final gallery had the following distribution of # the number of images /subject.

# of Subjects # of Images
6 8
25 9
469 10

total images= 4963
total subjects= 500

You should assume the system is symmetric. You may use the programming language/tool of your choice (R, Python, Matlab, etc) in the analysis of the data. Please indicate which tool/language is being used, and include a text file of code with your submission.

Files needed for this assignment (see Module 2):

Answer the following Question:

Genuine and Impostor Score Distributions:
a. Extract genuine and impostor scores from the similarity matrix.
b. Generate and plot the score distribution histograms for genuine and impostor scores on the same graph.
c. Additionally, plot the relative score distribution for genuine and impostor scores.
D-prime Calculation: Compute the d-prime (d’) value to assess the separation between genuine and impostor score distributions.
Receiver Operating Characteristic (ROC) Curve:
a. Calculate the True Positive Rate (TPR) and False Positive Rate (FPR) for varying thresholds. (a minimum of 10 thresholds.)
b. Plot the ROC curve and compute the Area Under the Curve (AUC).
Cumulative Match Characteristic (CMC) Curve: Generate a CMC curve to evaluate the rank-based identification performance of the biometric system.
False Match Rate (FMR) and False Non-Match Rate (FNMR) Curves:
a. Plot the FMR and FNMR curves on the same graph relative to the threshold.
b. Identify and mark the operating threshold that minimizes the difference between FMR and FNMR.

 

 

Understanding Surfactant and Neonatal Respiratory Distress

Posted on | by Kelvin

A newborn baby exhibits signs of respiratory distress due to the lack of surfactant. She has signs of low oxygen and high carbon dioxide. Explain the following in depth:

What is the role of surfactant, what cell secretes it, and when does the body start its production as well as when it is secreted?
Why does the lack of surfactant result in respiratory distress?
What type of acid-base disorder would the infant develop?
How would the infants body compensate for the acid-base disorder?

Access to Healthcare as an Individual’s Right

Posted on | by Kelvin

Introduction
There are 4 different “moral arguments” that help to explain views on healthcare provision. Below is a brief definition of each.

Utilitarian moral argument: to maximize the good and minimize the bad.
Egalitarian moral argument: to act on the principle that all people are created equal.
Contractarian moral argument: to act on the value of fairness (without bias).
Libertarian moral argument: to act on the value of freedom.
Your Tasks
Task 1- Original Post
Please respond to the following questions:
How would you explain access to healthcare and healthcare coverage as an individual’s right?
You will need specify at least one of the above moral arguments in answering this question. (10 points, 3 for specifying and explaining at least one moral argument)
In what ways is healthcare a privilege (whether actual or perceived)?

Cause of the elevated blood pressure, edema, and rhonchi

Posted on | by Kelvin

 

The home care nurse is seeing a 68-year-old Vietnamese woman for an initial visit. The patient was discharged from the hospital with a diagnosis of congestive heart failure (CHF). The home health nurse notices the patient’s blood pressure is elevated, and the patient has a productive cough. The patient speaks very little English. However, the patient’s daughter is present and able to interpret. The nurse completes a full health assessment, including a review of medications, and notes that the patient was prescribed a diuretic and a beta-blocker to regulate blood pressure. The daughter shares with the nurse that her mother does not like taking medications and chooses to take herbal remedies instead. Upon assessment, the patient’s vital signs are T 98.6 P 76 R 20 BP 160/80, 02 saturation 94%. The patient’s lungs are positive for scattered rhonchi in the upper bases, clear in the lower bases, rhonchi clears with cough. The patient’s heart rate is regular with no audible mummers, +2 edema bilateral in the lower extremities. The patient denies pain.

Question 1
Based on the information presented by the patient’s daughter, what is the most likely cause of the elevated blood pressure, edema, and rhonchi?

Answers may vary.

Question 2
What interventions should the nurse incorporate into the plan of care for this patient?

Question 3
What steps does the nurse need to take to become culturally competent?

Question 4
What interventions can the nurse include to provide care that reflects an acceptance of the patient’s health and illness beliefs and practices?

The Law and Our Legal System: An Analysis of Recent Developments

The Homeless Patient Evaluation & Management Plan
The nurse practitioner (NP) is working at a health clinic in a homeless shelter during the early evening. A 48-year-old African American man approaches the practitioner and asks to have his blood pressure taken, saying that he has not had it checked “in a while”.
The man appears to be in some type of distress and experiencing pain. The man walks slowly, using a guarded manner, and he appears diaphoretic. His mucous membranes also appear pale. The patient’s blood pressure is 210/98. The patient reports that he has not been diagnosed with hypertension previously. The patient reveals that he has severe abdominal pain that is radiating to his back. The nurse finds a heart rate of 110, respirations 30 with shallow inspirations, and temperature 102.2°F. The patient’s skin is cool and clammy.
The patient reports a history of alcoholism, homelessness, and lack of access to health care. He says that the symptoms have been present and worsening over 3 days. The man says he thinks he might have pancreatitis again, which he had “a couple of years ago”. The NP recommends that the man should be seen at a hospital for his condition, but the patient says he does not have health insurance, so he does not want to go.
The NP proceeds with a physical examination, finding severe abdominal pain in the epigastric area, yellowed sclera, no abdominal distention, and hypoactive bowel sounds. The clinic is equipped with basic materials but no means to conduct lab or radiologic testing.

Discuss the following:
1. Considering the patient’s homelessness and lack of insurance, what action should the practitioner take?
2. When the patient asks why his condition cannot be managed outside of the hospital, how should the practitioner respond?
3. When the patient arrives at the hospital for further diagnostic work-up, what tests will likely be performed to evaluate the patient’s condition?
4. How will the severity of the pancreatitis be assessed when the patient is hospitalized?
5. How should the patient’s condition be managed when hospitalized?
6. What patient education should be included after the pancreatitis is resolved?
