Note:Please describe what method/application you are using in each step. (so I can understand it) (and that the result is good, of course).

Consider an electronic device that monitors the temperature of exhaled air by a patient.The circuit is equipped with an NTC thermistor and additional circuits to sense the temperature and to trigger a visual alarm via two LEDs (i.e. a green LED and a red LED). The red LED is lighted when the temperature rises above a specific temperature and the green LED is lighted otherwise. Draw the electronic circuit of the device with appropriate power supplyconnections.Express how the value for the specific temperature can be set for the circuit in detail.

Software Requirement Engineering How to draw the Kano Model based on the answer attached. - to put each SF in the Kano diagram.

can you answer these questions on solar thermal collector experiment using the following bullet points. Why does correct positioning and weather affect the results obtained? Why it worked/failed. In your opinion, is Solar Thermal a useful technology for the UK? Avoid giving a binary answer and try to think of all variations of solar thermal technology and all regions of the UK. How would you modify the technology to become better/more efficient and more appropriate for the UK? If you were given the chance to do the experiment again, how would you do it and why? The answers to these questions should be supported by mindful arguments. This should occupy, at least, two pages of the report.

16. The average inside diameter of a sample of 2,000 washers produced by a machine is 0.550 inches with a standard deviation of 0.007 inches. These washers are manufactured with a maximum allowable tolerance in the diameter from 0.529 to 0.571 inches; otherwise, the washers are considered defective. Determine the number of defective washers produced by the machine, assuming that the diameters are normally distributed. (Round off your answer in whole number and without unit)

An electrical component has a reliability of 0.95 over 1,500 hours of normal use (note normal use indicates it follows an exponential distribution). What is the failure rate? What fraction will survive after 300, 500, and 1,000 hours? What is the MTTF?

Refer to the figure below in which surge protectors p and q are used to protect an expensive high-definition television. If there is a surge in the voltage, the surge protector reduces it to a safe level. Assume that each surge protector has a 0.94 probability of working correctly when a voltage surge occurs. Complete parts (a) through (c) below. TV Series Configuration Parallal Configuration a lf the two surge protectors are arranged in series, what is the probability that a voltage surge will not damage the television? Do not round.) b. If the two surge protectors are arranged in parallel, what is the probability that a voltage surge will not damage the television? (Do not round.) c. Which arrangement should be used for better protection? O The series arrangment provides better protection because it has a higher probability of protection. O The parallel arangment provides better protection because it has a lower probability of protection. O The series arrangment provides better…

A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 25-minute setup. Once in production, the PCB machine requires only 0.16 minute per board. a. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Currently, the PCB machine produces 600 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per minute)? (Do not round intermediate calculations. Round your percentage answer to 2 decimal places.) Currently, the PCB machine produces 600 boards between setups. Given this operating process, what is the utilization of the PCB machine? b.
