This is for my Computer Ethics class and is for a grade so please if you dont know the answer do not answer thank you. You are interviewing for the role of human resources manager for a large software developer. Over the last year, the firm has lost a number of high-level executives who left the firm to go to work for competitors. During the course of your interview, you are asked what measures you would put in place to reduce the potential loss of trade secrets from executives leaving the firm. How would you respond?

Problems are either the original work of the NAU instructors, modified from a number of materials science textsor taken directly from your Introduction to Materials Science textbook. It is required that these problems aresolved without referring to any answer key. Referring to an online answer key or keys from prior semesters isconsidered a form of academic dishonesty and will be handled according to University policy that is located inthe syllabus.Be sure to start each new problem on a new page. Don’t be surprised if a single problem extends past onepage of work.You are encouraged to work in teams, but turn in your own work. You are encouraged to get stuck and askquestions. Give yourself time to do so. Follow systematic steps to solve each of the problems. When workingon a quantitative problem, use the GIVE-FIND-SOLVE and REFLECT method. Identify what is given andwhat must be found. Do not simply rewrite the question. Show all work and carry units across work whenappropriate. You will not get full credit if you do not include units. Keep three significant digits in your finalanswer and place a box around the answer and units.Only one-two problems will be graded with fine detail, the rest will be evaluated based on to what degree youcompleted the problem and applied the correct principles. You will not know ahead of time which one-twoproblems will be carefully evaluated.1.1 In a table or matrix format, identify the three primary classes of solid materials studied in this course. Compare themain properties of density, strength (yield or tensile), fracture resistance and electrical conductivity of each class ofmaterial. Use Appendix B and C in the back of the book to get a sense of the relative magnitudes and costs of thesedifferent properties for these broad categories of materials. List an example of each kind of material and identifyapplications of how each is used.1.2 In table or matrix format, compare and contrast ionic, covalent, metallic and secondary bonds based on their strength,directionality. For each bond type, identify what classes of materials (problem 1.1) these types of bonds are found.Note, more than one bond type can contribute to a material class. Comment on the strength of the bonds, whetherthey are directional or non-directional and why, as well as

LTSpice and Lab Orientation – Instruments and Measurements

In this experiment, the student will become familiar with basic circuit implementation in

LTSpice and with using the lab equipment to be utilized throughout this course. In LTSpice there

will be DC and AC circuit simulation, Transient and AC analysis exercises. In the lab, the

equipment to be used includes the ADK oscilloscope, ADK signal generator and ADK network

analyzer.

In this lab, the student is expected to learn the order lab data should be collected for report

purposes, LTSpice and equipment setup and measurements, thus this experiment is structured

and step by step instructions are provided to achieve those objectives, later labs will not include

this format or level of detail except for special cases.

4. In the lab, build the circuit on your breadboard in Fig. 1.1, ensure resistor values by first

measuring the resistors using the MS8217 Handheld Multimeter set on Ohms.

Use the Analog Discovery Kit (ADK) to:

5. Measure and record Vout

6. Measure and record the current through R

Hint: You can measure the current (AC or DC) using one of the following ways:

Measure the voltage across the resistor from the ADK and divide by the value of the resistor

or Measure the current directly using your multimeter.

7. Use % Error to compare the calculated, the LTSpice, and the measured Lab results.

%| Error=(MeasuredValue-CalculatedValue)|*100/(MeasuredValue)
