ASU Summer 2017 Session C Week 7

The last full week of summer session c is coming to  a close. This week in EEE 203 the focus has been on the Z-Transform and its uses. Homework was fairly light this week. A bit more work and time was spent on the region of convergence, but as with the Laplace Transform, the lectures followed a similar pattern of looking at the definition, a couple of examples, regions of convergence, properties and then its application to LTI systems.

I spent a bit of time the past weekend working on the 40 point extra credit assignment. There are four parts to it looking at different applications of some of the concepts learned. Part 1 looks at the Discrete Fourier Transform, Part 2 Computation of DTFT using MATLAB, Part 3 Application of Communication System and Part 4 Application of Control System. I hope to spend a little more time over the next few days to look at these topics in a bit more detail.

In CHM 114, lots of work as usual. I took the third exam Tuesday night and did pretty well considering. Well above the average so was good enough for me given everything else on my plate this week.

Lectures and homework this week were on Chapter 19 – Thermodynamics and Chapter 20 – Electrochemistry. Chapter 20’s homework had 2 extra credit points. In addition to the homework, two guided activities and Lab 7 which was the Analysis of Ethanol.

Next week, Wednesday I’ll have my CHM 114 final and I plan to take my EEE 203 final on Friday 7/7. After that I’ll be on break for  about five and a half weeks and plan to enjoy some much needed rest and relaxation.

ASU Summer 2017 Session C Week 6

Another busy week. Getting close to completion of Summer Session C. EEE 203 this week has been focusing on the Laplace Transform. Lectures included a look at:

  • Definitions
  • Examples
  • Inverse Transforms
  • Properties
  • LTI Systems
  • LTI System Examples

I had a little bit of trouble sorting out the region of convergence, but I found a slide deck that had some nice worked out examples.

This week the instructor provided two MATLAB examples. One on an RLC Band-pass Filter and a Cruise Control example. I haven’t had a chance to look much into these yet.

With the exception of one of the homework problem, most this week were pretty straight forward which was a nice change.

I was able to get the 20 pt midterm reflection wrapped up and submitted. After the midterm, definitely trying to get all the extra credit possible.

CHM 114 continues to consume almost all of my time. This week 3 chapters were covered, Chapter 14 – Kinetics, Chapter 15 – Equilibrium, Chapter 16 – Acids and Bases.

Last week’s material and this week’s material will all be on Exam 3 which opens up next week. I plan to spend a good part of this week reviewing the practice exam and trying to keep all this stuff straight.

The lab this week was a titration tutorial, again using the late night labs. The guided inquiry activities covered Reaction Rates and Introduction to Equilibrium.

 

ASU Summer 2017 Session C Week 5

Are we done yet? I don’t think I have ever been so tired. This past week I had a midterm on Monday in EEE 203 and a CHM 114 exam. Toss in the usual EEE homework and quiz, and in CHM 114 only 3 chapters, Mastering Chemistry homework, a lab, a discussion board post and two interactive guided activities.

I thought for sure I was done for on the EEE 203 midterm. I did horribly on the multiple choice portion of the exam. I was really nervous and made some really dumb mistakes. 4 is not the same thing as -4. I did slightly better on the short answer portion, but the midterm showed me a few areas I really need to pay better attention to.

CHM 114 I passed and did slightly better than the average. I didn’t spend much time preparing for this test and it really showed. but still doing okay in there. There just aren’t enough hours in the day. There wasn’t a lot of math problems, mostly conceptual questions and some were really tricky. At least it is done.

This week in EEE 203 we’re turning our attention to Discrete Time Fourier Transform and Sampling. I’m a bit behind and haven’t gotten through the sampling lectures, but there are some things that are pretty similar to discrete time, but you’ve got a few differences that you need to be aware of. So far it seems slightly more straight forward than the first few weeks, but occasionally you’ve got a partial fraction to deal with.

The professor added a midterm reflection assignment which will give 20 points following reviewing all problems missed and reflecting on ways to improve. I plan to work on that this weekend.

In CHM 114 this week the three chapters covered

  • Ch 10 – Gases
  • Ch 11 – Liquids and Intermolecular Forces
  • Ch 13 – Solutions

The lab this week again used the Late Nite Lab site and covered Molar Volume of a Gas. It wasn’t too bad. Hopefully I answered the questions correctly and reported my values properly . I’ve had a few points marked off for significant figure issues the last few times. Nothing major but irritating. I never had that problem in the physics labs. Probably just being careless but when you’re up at 7 and working until 11:30 with breaks for meals just trying to stay slight ahead, not sure what more can be done.

Is this session over yet??!?

 

ASU Summer 2017 Session C Week 4

Hard to believe I’m over half way done with this summer session of classes. Next week I have the EEE 203 midterm and CHM 114 exam 2. This week I’ve been reviewing the materials while trying to juggle a lot of work. I am tired this week, I’ve had a lot of very late nights up till midnight or later working on my studies.

In case you’re wondering, here is a glimpse of what the work load looks like…

EEE203vsCHM114

I really wish CHM wasn’t taking up so much time right now. I fear I’m going to pay for it come Monday on the EEE 203 midterm. I’ve completed and submitted 8 quizzes and homework assignments for EEE 203, ten graded items remaining between midterm, final, homework, extra credit assignment and quizzes. CHM 114, 27 assignments completed between Mastering Chemistry homework, labs, guided interactive activities, discussion board posts and tests. Only 24 more to go.

In EEE 203 this week the focus was on the Continuous-Time Fourier Transform. All material from Chapter 4 in the textbook.

  • Fourier Transform Definition
  • FT Examples
  • FT Properties
  • FT & RC Filtering
  • FT & Amplitude Modulation

I need to spend a little more time understanding the RC Filtering and Amplitude Modulation examples that were given. Its been really tough this week balancing everything with all three kids home.

Still feels like learning a whole new way to do math, but this week’s homework assignment went much smoother than the last few weeks. I won’t see any of the Chapter 4 information on the midterm though, only chapters 1 through 3 are covered.

I haven’t had a chance to look through the MATLAB examples that the professor posted this week. I really chemistry wasn’t taking up so much of my time. Definitely glad it will be the last non EEE class I’ll have!

CHM 114 covered three chapters this week:

  • Chapter 8 – Basic Concepts of Bonding
  • Chapter 9 – Molecular Geometry and Bonding Theories
  • Chapter 12 – Solids and Modern Materials

In addition to the lectures there were three homework assignments, a Lab 4 – Strength of Alka Seltzer, two activities on Molecular Geometry and Polarity and Semiconductors and LEDs. If that wasn’t enough there is also a discussion board post.

All of the videos have been pretty good although Chapter 12 was way to brief for the number of homework problems. A lot of the questions in the homework I had to dig through the book to find. Hopefully things improve on next week’s lectures.

The chemistry test next week will be on Chapters 5-9 & 12. The professor has a practice exam posted and will be going through that this weekend. I’ve continued to keep up with my flash cards and added in some of the various molecular geometry shapes and arrangements we’ll need to have memorized. Hopefully won’t be too bad. There hasn’t been a lot of math the past few chapters so hopefully the exam will be pretty straight forward. I vaguely remember some of this material from CHEM 1A and 1B at UCR but that was 20 years ago.

ASU Summer 2017 Session C Week 3

Another insanely busy week. While still over a week away, I’ve started prepping and studying for the upcoming closed book/closed notes EEE 203 midterm. A bit nervous about this one. Lots to remember and a lot of complex math dealing with trig to exponential conversions.

I keep meaning to write up more about the EEE topics and some of the problems I’m working on, but just flat out haven’t had a chance to go into detail.

This week in EEE 203 I started looking at the Fourier Series. Over 15 lectures this week covering:

  • Complex Exponentials as Eigen Functions
  • Continuous Time Fourier Series
  • Continuous Time Fourier Series Properties
  • Discrete Time Fourier Series
  • Discrete Time Fourier Series Properties
  • Fourier Series LTI System Continuous Time
  • Fourier Series LTI System Discrete Time
  • Filter Details

The EEE 203 homework is taking me a bit longer to work through this week and I probably won’t get to the week 3 quiz until Saturday or Sunday. There are a couple questions I think I need to double check that I did earlier in the week after seeing the instruction teams responses on the Piazza discussion board. So far though, I’ve gotten perfect scores on the homework and quizzes and still have a small surplus of extra credit in the bank.

The topics are interesting but definitely a lot of math involved in this course. I wish I had taken it closer to the completion of MAT 265/266/267. I’ve gotten rusty! I keep hoping that an “easier” way will present itself, but so far its definitely some very detail oriented math work to calculate the various functions of Fourier series coefficients. It’s so easy to misplace a negative sign along the way.

The professor recommended a supplemental book titled “Schaum’s Outlines – Signals and Systems by Hwei P. Hsu. I’d ordered it last week and it finally showed up today. Hoping that will help me get a different perspective and better understand this stuff.

In CHM 114, I took the first exam on Tuesday and scored an 88/100 with the average at 72% so feeling pretty good about that. I haven’t gone back to review what I missed yet, just haven’t had time.

This week, only two chapters were covered:

  • Chapter 6 – Electronic Structure of Atoms
  • Chapter 7 – Periodic Properties

This week’s lab covered Spectroscopy Analysis and the two activities were on Spectroscopy and Atomic Energy Levels and a second on Photoelectron Spectroscopy.  In addition, also had two chapters worth of Mastering Chemistry homework and the weekly discussion board post to do.

I am tired. Feels like all I have do is wake up, sit at the computer and do homework and watch lectures. Definitely feeling a bit burned out this week.
