Circle your choices.Fowler-Nordheim Tunneling refers to(The four I-35 tunnels in downtown Duluth, The mechanism for charge injection and storage in a NAND transistor used in your flash drive, The process for creating the pits to define bits on a DVD).Most of us who have a desktop and/or laptop computer and/or television continuously plugged into the power system, operate in a standby mode 24/7. Assume the standby power requirement averages 50 watts. If electrical energy cost 9.0 cents/KWH ($0.09/kilowatt hour), how much does it cost to operate either a computer/laptop/television in standby mode 24/7 for one year?Photonic devices operating in the red or infrared portion of the spectrum typically include [Germanium (Ge), Silicon (Si), GaAs, Silicon Dioxide (SiO2), GaN] and photonic devices operating in the blue end of the visible spectrum such as LED lighting and BluRay video players and the Sony PS5 Game System include [Germanium (Ge), Silicon (Si), GaAs, Silicon Dioxide (SiO2), GaN] Circle your choices.Briefly discuss the impact that Hedy Kiesler Markey had in signal processing.There are fiber optic links between the UMD and UMTC (UM Twin Cities) campuses. How long does it take a signal propagating at the speed of light to traverse the distance from MWAH to the UMTC campus? Assume the distance is about 300 km. The U.S. and Canada standards for power distribution are(110-120 volts DC, 110-120 volts rms AC , 220-240 volts DC, 220-240 volts rms AC) with an operating frequency of (0 Hz, 50 Hz, 60 Hz, 400Hz) with a (SQUARE, TRIANGULAR, SINUSOIDAL) wave shape and the power distribution standards in Europe and parts of the Asia are(110-120 volts DC, 110-120 volts rms AC , 220-240 volts DC, 220-240 volts rms AC) with an operating frequency of (0 Hz, 50 Hz, 60 Hz, 400Hz) with a (SQUARE, TRIANGULAR, SINUSOIDAL) wave shape. Circle your answers.Pre-1860 wet chemistry photography often used AgI (Silver Iodide) as the photosensitive material and Hg vapor was used to develop and fix the image. In retrospect, this was a dangerous technique which would no longer be an accepted safe practice. Why was this technique detrimental to the health of early photographers? In retrospect, which one of the ten IEEE Code of Ethics statements would have been applicable. Which of the following are effective in saving electric energy thereby reducing your monthly payment so that you have more pizza and beverage money in your pocket, and also minimizes the impact on the environment._____Replacing incandescent lighting with LED lighting_____Unplugging your computer and television rather then using stand-by mode when not in use for an extended time._____Using time-of-day pricing if available in your area._____Minimizing the use of resistive electric heat and air conditioning_____Using a heat pump for HVAC_____Use of a “smart thermostat” for setting your home environmental temperature_____Replacing CFL (Compact Florescent Lights) with LED lighting_____All of the AboveProblem 2 (30 Points) “Henry’s Daughters” Video(30 Points; 6 Points Each) List and briefly describe five of the unethical, unprofessional, or outright illegal behaviors depicted in the “Henry’s Daughters” video. Be specific! In addition, which ones of the ten IEEE Code of Ethics statements are most applicable. You could list more than one with justificationUnethical, Unprofessional, or Outright Illegal Behaviors Depicted in the “Henry’s Daughters” Video.IEEE Code of Ethics Statement Number(s)1.2.3.4.5.Problem 3 (72 Points, 9 Points Each) IEEE Code of Ethics ScenariosYou are visiting a potential supplier and vendor for items your company is buying. You are invited to their break room for a cup of coffee and a stale donut. Is there an ethical or legal issue in accepting a cup of coffee and stale donut as part of the business meeting? YES or NO and briefly explain.You are visiting a potential supplier and vendor for items your company is buying. After some price and delivery negotiations, you are invited to lunch and drinks at a high end restaurant like Bellisios or the New Scenic Café. Is there an ethical or legal issue in accepting this this pricey luncheon invitation? YES or NO and briefly explain. Answer in terms of the IEEE Code of Ethics.After a difficult, and perhaps acrimonious, design review meeting, you get on FACEBOOK and TWITTER and lambast the project manager using every rude name and physical action that comes to mind. You may feel better after this tirade but is there an ethical or legal issue. YES or NO and briefly explain. Answer in terms of the IEEE Code of Ethics.Now revert to being a student. You asked to write a research paper for one of your courses that you are not really interested in. Since you are bit short of time and/or motivation, you submit a paper from , or any number of WEB sources depending upon how much you are willing to pay and the topic. Is there an ethical or legal issue? YES or NO and briefly explain. Answer in terms of the IEEE Code of Ethics.Again, revert to being an electrical engineering student. When you go home over winter break, you are asked to help your parents and grandparents set up a movie room video paradise with surround sound, computer control of everything, wiring for laptops, and comfy chairs. You explain the system operation and even write up a brief operations manual including wiring and safety information. You do this willingly. (Perhaps you will get a free meal or two!) What IEEE Code of Ethics would this fall under?Your company is in a financial position to offer its employees technical seminars and short courses on new and important developments that are critical to corporate success and the bottom line. You are indifferent to these opportunities and most of the time you find a reason to blow off these opportunities to improve your technical competence. What is the IEEE Code of Ethics issue?You manage an engineering department. One of your responsibilities is to review employment applications. You request a photo with the application. Is there an ethical or legal issue? YES or NO and briefly explain. Answer in terms of the IEEE Code of Ethics.As the CEO of an engineering company, you ascertain that some changes in environmental and regulatory issues are needed to perhaps increase the bottom line. You find a way to divert a quantity of corporate dollars to the election committees of chairs of appropriate State Commissions. Is there an ethical or legal issue? YES or NO and briefly explain.
