3.1 Modules in PV Systems EQ3.1.1 Modules in PV Systems 1.0/1.0 point (graded) Consider a crystalline PV module with the following output parameters mentioned at STC (Standard Test Conditions) conditions by the manufacturer. Pmax = 250 W Voc = 50 V Isc = 6 A NOCT = 40°C Temperature coefficient of power = -1 W/°C If the ambient temperature falls to 0°C while the irradiance is 1000 W/m², what is the cell level temperature in °C, as per the NOCT model? 25 correct You have used 2 of 3 attempts Some problems have options such as save, reset, hints, or show answer. These options follow the Submit button. EQ3.1.2 Modules in PV Systems 1.0/1.0 point (graded) What is the new power output of the PV module in watts, under the ambient temperature of 0°C and 1000 W/m² irradiance? 250 correct You have used 2 of 3 attempts 3.2 MPPT Concepts EQ3.2.1 MPPT Concepts 1.0/1.0 point (graded) Consider a PV module with the following parameters as measured at STC (Standard Test Conditions): Voc = 55 V; Isc = 5 A; Impp = 4.7 A; Fill factor = FF = 75% ; Efficiency = 19.75%. Suppose that under normal operation at STC conditions, the module is not connected to an MPPT device, and is instead directly connected to a purely resistive, variable load 'R'. The load R can be tuned to give a resistance between 0 to 1kΩ. What value of resistance will you keep the load at, if you wish to derive maximum power from the PV module under STC conditions? R = 9.34Ω. R = 11Ω. R = 11.71Ω. R = 5Ω. Irresp ...

SNHU Millennia Health Center Hospital Management System Presentation

Imagine that you are on the same project team for the new IT system for the Millennia HealthCenter (MHC) that you were on for Project One and Project Two. The new software system that you created the system requirements specifications and the implementation plan for has successfully gone through all of the testing tasks in the testing phase. Before you implement and release the new system, the application development team and the project's stakeholders would like you to give them a quick presentation on the overall solution. Prompt Create a 4-page presentation about the solution, the newly implemented software system for MHC. In your presentation, you must: Introduce the system, its name, its purpose, and the problems that it will solve. Highlight the main features of the system. Demonstrate what the system will do and its functionality. (Although you won’t physically demonstrate the functionality of the system, describe how the system would function if you were to demonstrate it to the stakeholders.) Explain the potential capabilities for the system, and the future direction that the system could go in. If you use MS PowerPoint to complete this activity, it is recommended that you leave notes to account for what you would be speaking. Your visual should be uncluttered, and the Notes section in PowerPoint is a great way to build on your ideas without adding more text to your slides. You may find this resource helpful: Add Speaker Notes to Your Slides.

BE 3320 Effect of Coughing on Heart Rate Lab Report

Lab report and must have the sensors to check heart rate to do this lab. Effect of Coughing on Heart RateInvoluntary coughing is the result of irritation of special sensory nerves in the respiratory tract. This helps to clear potentially damaging substances from the lungs (water, foreign bodies, dust, infection, mucous, etc.). Coughing can be more deleterious than helpful, causing discomfort, preventing sleep, or leading, in some cases, to dizziness or loss of consciousness (known as cough syncope).The physiologic effects resulting from a cough are numerous. There is marked increase in intrathoracic pressure just prior to expulsion of air. When blood pressure is normal, this leads to a decrease in venous return to the right side of the heart and a decrease in cardiac output. On the other hand, a cough-induced increase in intrathoracic pressure may provide a form of “internal cardiopulmonary resuscitation” in a heart attack victim whose blood pressure is falling dangerously low. In this case, coughing can be as effective as the external chest compressions of CPR in raising blood pressure and providing better blood circulation to vital tissues. Coughing, and the resulting wide fluctuations in intrathoracic pressure it produces, causes reflex stimulation of the autonomic nervous system. The sympathetic nervous system is an “activating system,” preparing the body for a “flight or fight response” by increasing heart rate and blood pressure. The parasympathetic nervous system acts through the vagus nerve to slow the heart and to lower blood pressure. Both the sympathetic and parasympathetic systems may be stimulated or inhibited by physiologic stimuli or medications. The following table shows potential heart rate response to stimulation or inhibition of the sympathetic or parasympathetic nervous systems:Branch of Autonomic Nervous SystemHeart Rate Response toStimulation InhibitionSympathetic ↑ ↓Parasympathetic ↓ ↑In this experiment, you will observe the response of heart rate to coughing, and correlate this response to activity in the autonomic nervous systems. Important: Do not attempt this experiment if you suffer from asthma or any condition that may be aggravated by repeated coughingDATA ANALYSIS FOR LAB REPORT1. In what direction did your heart rate change in this experiment? According to the table in the Introduction, what are the possible explanations for this change?2. There are medications that can selectively block the action of either sympathetic or parasympathetic influences on the heart. How could such medications be used to determine which of these systems is responsible for a change in heart rate such as was seen in this experiment?3. Compare the response and recovery times recorded in Table 1. List possible survival advantages of the differences you see.4. The parasympathetic and sympathetic nerve supplies are severed during heart transplantation and are not surgically repaired. Would a heart transplant recipient’s heart rate change with coughing (or with a severe fright)?5. You are in a remote location and a member of your party complains of chest pain and dizziness. You find that his pulse is 35 bpm. You immediately call 911 and are told that it will take 15 minutes for the helicopter to arrive. You know that CPR should not be performed on conscious individuals. Drawing from the knowledge you have gained from this experiment, what might be done to improve your patient’s pulse and blood pressure?6. Perform the experiment with different coughing frequencies and intensities.
