Negative Temperature Coefficients (NTC) -Research Paper

Order Description

Many types of sensors have a nonlinear response. This limits both the range and accuracy of measurement. Analogue circuits can be used to compensate for the nonlinearity of the sensor. These circuits can be complex and inadequate to cope in many situations. There are a number of software techniques that can be used to compensate, more effectively, for the nonlinearities of sensors. These can rely on developing an accurate model for the sensor.

In this task you are required to explore different software based techniques to compensate for the nonlinearities of a negative temperature coefficient (NTC) resistor sensor and select one appropriate technique and justify your choice. A good literature review is required. Demonstrate your solution using LabView and/or Matlab by fully building a hardware prototype which incorporates an NTC temperature sensor. You are required to evaluate, in detail, the improved accuracy of the sensor.

You need to submit a written report detailing the following:

1. Introduction
2. Literature Review
3. Design and construction details
4. Testing
5. Results and analysis
6. Conclusions
7. References

The value of the thermistor used is 150kohms and resistor 68kohms. the introduction and conclusion should be very good.

Whole life Concept pt. 2 -Essay

Order Description

Throughout the semester you have learned about the various engineering disciplines and subdisciplines. You have also learned to use some of the tools and techniques of the profession. As you
finalize your personal career plan, think about how you will apply your new knowledge, skills, and abilities upon graduation to positively impact the world.

-Review of Part 1
• Briefly summarize your passion as you discussed it in Whole Life Concepts Paper, Part 1.
• Briefly summarize how you wish to use your passion to impact the world as you described it in Whole Life Concepts Paper, Part 1.
• In Part 1 of this assignment you researched three existing job opportunities for turning your passion into a career. Briefly summarize, with specific details and examples, the technicalknowledge, skills, and abilities will you need to prepare yourself for success in those jobs.
• Briefly summarize, with specific details, the non-technical knowledge, skills, and abilities will you need to master to prepare yourself for success in the jobs you identified.

-Knowledge and Skills
• Identify the specific academic program (your major, concentration within a major, and potential
need for graduate study) that is the best fit for you in terms of turning your passion into a
career. Identify and detail specific courses and laboratories, the course content and prerequisite requirements that will provide you with the fundamental academic knowledge needed to be successful with your selected academic program. Explain how the academic program you have chosen helps you achieve your desired impact.
• Provide three specific examples of course material you expect to use to achieve your desired impact. For example, you may choose to take a course in nuclear engineering to develop your knowledge of nuclear power plants.
• Identify and provide details of the sources you will use to develop the specific non-technical, non-academic knowledge, skills, and abilities you will need to achieve the impact you desire. Provide three specific examples and explain how the non-technical, non-academic programs you have chosen will help you to in achieving the impact. For example, you may choose to become involved in Toastmasters, Inc. to develop your public speaking capabilities.

-Reflection and Conclusion
• Reflect on the Whole Life Concept and Disciplines model. Summarize three examples of why it is
important to you at this stage of your academic/professional career.
• Reflect on this assignment and the work you have devoted to it. Describe in detail and provide
three examples of how this assignment has influenced your perceptions, choice of major,(assuming you have chosen one), and plans for the future.
• Reflect on your commitment to your engineering, engineering technology, or construction management degree. Describe in detail why you are – or are not – more committed now than before to your chosen major, the College of Engineering, and/or UNC Charlotte.

-Successful Completion
Use 1” margins (top, bottom, and sides) with 10 point font only. Font styles are limited to Times New Roman, Arial, or Calibri. Use appropriate headings in bold and/or italicized font to distinguish between sections and sub-sections. Your document must be single-spaced except in between sections or subsections. It must be 3-5 pages long not including the Title page or Reference page. All references must conform to the format specified in the Chicago Manual of Style. The Title page must include the title of your paper, your name, the ENGR/ETGR 1201 section number, and the submittal date. The Academic Integrity statement must be included on the title page in accordance with the policy on Moodle.


Advanced Digital Systems -Coursework

Order Description

Your task should be done in Matlab 2007 in the Texas Instruments area of the University systems.
You will create a sine wave signal at 1 kHz, and amplitude 0.1 (no units) using the DSP sine wave
generator. You will then add to the sine wave signal a noise signal, created using ??�random source’, of
amplitude 0.1 and uniform sampling. Then use FDATOOL to design a filter that has the function of
eliminating the audible noise and passing the sine wave. In other words it must decrease the
amplitude of the noise by 40 dB. The system sampling rate is 16 kHz. The filter should be of
maximum 8
order. Note from the diagram below that a scaling factor is normally needed as the filter
may have gain or attenuation at the sine wave frequency. Make particularly sure you check the signal
carefully when doing audio monitoring. It is good practice to hold the headphones away from your
head when checking signal levels.
You will then need to plan and execute a series of tests on your design which must use the time
scope and spectral analysis plots before and after filtering. You may use the vector concatenate
function to combine the signals to reduce the number of spectrum plots. The time scope can be
configured for two input signals. Use the audio output to help you to discern whether your filter has
worked but remember that it does not cooperate well with the two scopes so you will need a
switching facility or separate with audio/without audio models.
The absolute maximum level of the DSP sine wave and the random source shall be 0.1 units in
the menus that appear when you click on the blocks. This is to prevent damage to your ears if
you are wearing the headset and the signal suddenly starts playing. Pure sine waves in
particular can cause serious ear pain.

Your mark will consist of the following components

a. A section entitled ??�Design Justification’. Choose, with the help of text books and other resources, a
basic structure and a set of parameters for the design of the filter. You will need to gain enough
knowledge of different filter types to be able to choose suitable blocks and specify critical points in the
design. Document each of your design choices (including FDATOOL parameters) carefully and write
a detailed justification of your choices. Create the design as described above in Simulink. Describe
this model in your report and upload the .mdl file to the module web. The expected length of this
section is 6 pages with at least 10 references.

b. A section entitled ??�Testing’. You must describe your test plan and how you chose it. You need to
document the series of tests that you did providing information in textual and diagrammatic form. You
must provide information on what your tests prove. The expected length of this section is 2 pages .

d. A section entitled ??�Conclusions’. Referring back to the assignment objectives, explain how your
results have proved that the objectives have been met. Also include a short literature study into one
alternative method of implementation using programmable logic devices like FPGAs or CPLDs. The
expected length of this section is at least one page, with at least 4 reference .

so I want from you to write 6 pages in research for the first part ( a )

for ( b) I did the design of the program and I have pictures of all the choices that i made ??and the results of the test so i want from you to write 2 page about my testing and my results ( every picture need some explanation
