Write a 12 page essay on Sensors and Control Systems (Electrical and Electronic Engineering).

Rotating a DC electric motor’s rotor like tacho generators will produce electricity and voice-coil speaker can also act as microphones.

It consist of a nickel wire of 0.5-1 mm diameter kept stretched between the poles of a permanent magnet and having a small stylus rigidly attached to it at the mid-point. The wire is prestressed by twisting it, before being installed into the position. Two pick-up coils of fine wire are wound round the wire on either side of the mid-point. Any displacement of the stylus to one side or the other increases the torsion on the side and decreases it by an equal amount on the other side. This results in an increase of magnetic flux in one-half and a decrease in the other half. The corresponding induced emfs are in phase opposition and are processed by suitable networks as in the case of linear variable differential transformer. It is used as phonograph pick-up and is designed to have flat frequency response over 150 Hz- 15 kHz frequency range. Due to the nonlinearity and hysteresis in the performance, it is normally limited for use when time- varying torsions of small amplitude are to be measured.

It was discovered in 1879 and belongs to one of the galvanomagnetic phenomena in which the interaction between the magnetic field and the moving electrical charges results in the development of forces that alter the motion of the charge. When an external magnetic field is applied to the current carrying hall element perpendicular to the current flow a Lorentz force acts on the current due to which a voltage called hall voltage is generated perpendicular to both the current and the magnetic field. This voltage is so small and needs amplification.

If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the

ANTHROPOLOGY CONCEPTS: 1. What is anthropology? What are its characteristics? What are the subfields of anthropology? 2. What is the scientific method? 3. What is an anthropologist”s primary ethical obligation? What are some important legal and ethical considerations for anthropologists as they conduct their research? 4. Identify the specialties within physical (biological) anthropology and archaeology that contribute to the study of human origins. What unique methods might these specialists use in their work? 5. What are the best circumstances for fossilization to occur? What types of remains can be fossilized?

Answer the following questions: Security A has an expected rate of return of 6%, a standard deviation of returns of 30%, a correlation coefficient with the market of 0.25, and a beta coefficient of 0.5. Security B has an expected return of 11%, a standard deviation of returns of 10%, a correlation with the market of 0.75, and a beta coefficient of 0.5. Which security is riskier? Why?The standard deviation of stock returns for Stock A is 40%. The standard deviation of the market return is 20%. If the correlation between Stock A and the market is 0.70, then what is Stock A’s beta?An analyst has modeled the stock of Crisp Trucking using a two-factor APT model. The risk- free rate is 6%, the expected return on the first factor r1 is 12%, and the expected return on the second factor r2 is 8%. If bi1 0 7 and bi2 0 9, what is Crisp’s required return?Stock A has an expected return of 12% and a standard deviation of 40%. Stock B has an expected return of 18% and a standard deviation of 60%. The correlation coefficient between Stocks A and B is 0.2. What are the expected return and standard deviation of a portfolio invested 30% in Stock A and 70% in Stock B? Your paper should meet the following requirements: Be approximately 2 pages in length, not including the cover page and reference page.Follow the CSU-Global Guide to Writing and APA (Links to an external site.)Links to an external site.. Each paper should include an introduction, a body with at least two fully developed paragraphs, and a conclusion.Support your answers with the readings from Module 4 and at least one scholarly journal article.

Please see the screenshot below and show your work. Thank you.

Last Tuesday, Cute Camel Woodcraft Company lost a portion of its planning and financial data when both its mainand its backup sErvers crashed. The company’s CFO remembers that the internal rate of return {IRR} of Project Zetais 11.3%, but he can’t recall how much Cute Camel originally invested in the project nor the project’s net presentvalue {NW}. However, he found a note that detailed the annual net cash flows expected to be generated by ProjectZeta. They are: Your Cash FlowYear 1 $2,4flfl,flflflYear 2 $4.5flfl,flflfl Year 3 $4,5oo,ooo”fear 4 $4,5oo,ooo The CFO has asked you to compute Project Zeta’s initial investment using the information currently available to you.He has offered the following suggestions and observations: . A project’s IRR represents the return the project would generate when its NP‘v’ is zero or thediscounted value of its cash inflows equals the discounted value of its cash outflows—when thecash flows are discounted using the project’s IRR. – The level of risk exhibited by Project Zeta is the same as that exhibited by the company’saverage project, which means that Project Zeta’s net cash flows can be discounted using CuteCamel’s Flue WAGE. Given the data and hints, Project Zeta’s initial investment is , and its l’ilP‘vr is{round ed to the nearest whole dolla r).
