I'm sleepy today... I should probably update on what I've been up to.

Currently working on studying for Midterm for Computer Architecture (test tomorrow).  I'm also trying to figure out how to plot how threshold voltages and transconductances change over time in Cadance easy.  I recently finally understand how C-Elements and 4 phase communication works.  Setup a Matlab example.  Problem I had was for my C-Element, I wanted it to only have two inputs and a single output, but also retain the information of the previous state.  So I used a global variable... problem with this is in the 4 phase communication, each C-Element now needs its own variable.  I don't want to pass in the previous state.  So I used 2 temp variables to store the old states between calls at the higher level.  I'm going to have to re-design this.  Probably need to do it down to the gate level (add in unique delay for each type of logic depending on how I physically design it... but then the question comes up... can I run them in parallel in Matlab... I think yes in simulink or if I'm them a cell in a matrix... but not 100% sure... have tried it yet).  Kind of a simple first order approximation thing... oh why am I doing this.  To help with a few of my research projects.

But today... I'm feeling lazy...

So... just got up about an hour ago.  Yesterday was my first picnic day at UCDavis.  It was really a hoot and tones of people.  I did the following things:

Helped with setup Electrical Engineering projects for display that day.  The undergrads in EEC 136 did some really cool projects (I'll put up a link to them later).

Musical Stairs
3D Snake game
Pulse Oximeter

I took off to the Dog race the vet school was showing off.  On the way there I saw a helicopter land right in front of me, ~200 feet (which was cool).  After that I went walking around, they had the band playing by the little lake on south campus.  Lots of food, had some ice cream.  Saw the cows and goats.  Now I had a lot of fun at Davis Dance Revolution (I'll put a link later).  There were some really good groups...

I'm tired today... but off to lab.  Today I'm working on homework and reading... maybe a bit of research.

ITS FRIDAY THE 13TH WAHAHAHAH!  The photo is my mom in front of the Century Plant blooming today.  Happens usually once every 10 or so years.  Though the last time it bloomed was 15 years ago, it was a plant about 2 times as high as the current one... it died shortly afterwords.  This is the baby that sprouted up afterwords.  They don't always die after blooming... but oh boy... when they do... they smell bad... and almost impossible to get the stench out of any clothes you use to remove it width... any ways, its a very lovely bloom and plant :P.

This link is targets at Ram, irregardless is a word... lolz I will use it when I want to.  Even though the dictionary warrants me to not use this word.

So far not a bad week... except my last 3 dinners haven't agreed with my stomic... don't feel like trying to look up the spelling of stomic (tummy).  I had Vietnameses (think I spelt it right) 3 nights ago...

did have a decent swim this afternoon.  Now back to collecting data... want to get out of here at some what of a reasonable time... took me 2.5 hours to gather half the data I have left... so I'll probably finish around 2am... arg... :|

Well I finished watching season 16 of Top Gear and I think season 5 of Doctor Who.  Doctor Who just keeps getting better and a bit more twisted.

It is also the end of my first week.  Even though I'm only taking one class, research is going to keep me very busy... I'm not 100% sure when I'll get to start reviewing the EEC 211 material... :|...

other than that... I'm doing well... quite tired... oh yeah half my room lost power.  For my own record, only two of the outlets work.  The one on the North wall near the sink and the one on the East Wall that shares with the bathroom next to the little "fridge" closet I have.  The out lets on the main East, West, and South walls do not work.  Only the light on the North wall works, the rest do not turn on... also note... my battery backup system didn't work long enough for a proper shut down of my main desk top computer...

First day of Spring Quarter.

Today was a lovely day.  I went to the Digital IC class I'm auditing and my Computer Arithmetic Architecture class (my only class for a grade).  So far not too bad... got a little homework and chapter 1 to read :).

I'm currently in lab reading some awesome work done by a German research group.  They got there logic family to work at 0.62 mV for 0.13 um technology... I have much to learn...

I had a good long swim today, watch a little Top Gear, and I'll go home soon, where I'll watch a little Dr. Who and fall a sleep.

Have to do a long of reading tomorrow... well every day... lolz only trying to read one page today... its so dense... I don't know how people read so fast... I have to read a sentence... think about... maybe draw an image, re-read... and then go ah... kind of get it... go to another resource... and then go AH!!! Now why?  Then I ponder... think... ponder some more... and realize that 15 minutes has gone by on one sentence... *not typical for all sentences... just a good chunk of them*

On vacation back in Texas :)... yeah haven't posted any thing in a few days.  Still kind of recovering from my rough quarter.  So far it looks like I did decently well in my classes.

Well enjoy your spring break if your on it,
back to Doctor Who for me :P,

Tick, Tock, Tick, Tock... ;)


To day is my brother's birthday!!!  I'll have to remind my self to say happy birthday to him.

I now have officially 35h 56m left in the hell week... AGGGG!!!!!!!!!!!!!!!!!!!!  That is all I have to say... I really got to learn to balance my class load better... I DON'T CARE WHAT YOU SAY MR. ADVISOR... 55m... I CAN DO IT!!!

Back to work...

Yeah got more work to do... its been a while since I posted, been very busy... getting close to wrapping up my lower power digital IC final project.


Heading back to Lubbock for Spring break.

good night,
back to work with me,

Students log...

New monitor... and not running 100% right now.  Over the last 2 or 3 days... they are blending now... I haven't been able to sleep more than a few hour in a row.  Though this afternoon I took a nice 4 to 5 hour nap.

List of grad students at UCDavis


My current setup, and yes rubble screening the MAC.  Using Linux bot for storage, and remoting in from both to another linux box due to not having every thing setup on this linux box.  A bit complicated, but got it all working :).  Though, later today, I should get my 21.5" wide ACER in :D!!!  I'll have to set that up tomorrow hopefully.  On a side note, really starting to add a lot to my Cadence page... its a work in progress.  I'm soooooo.... sleepy today.  I stayed up late, but had to wake up early.  I don't like missing class.  I've only missed 2 classes my whole grad life.  First one due to being out of town due to job interview and 2nd due to staying up all night and crashing the next day.  

My project for Low Power Digital Design IC is coming a long a bit slower than I'd hope, but that was partly due to changing technologies.  Well got some emails to reply to.  Have a good day... maybe a short nap too before class (had Lamb Gyro for lunch... early lunch :P).   Its raining again today.  2nd day in a row I think.  
I was out side when I took this... and all other doors I saw have this same label... its a paradox door!!!  WOOT!!!

Its late...

Today I finished up my device physics homework, yesterday I finished up Analog IC signal processing homework, and late tonight (well really Sunday night... since I haven't gone to bed I still think it Sunday...) I got started on my Digital project (its going to be fun).

Nothing much happened... I keep leaving my tea brewing too long and I get a strange film from the leafs form on top... it taste fine... but got to be better about just brewing it for a bit... this link was given to me by Chua.  Most of the time I get my tea right... but been more distracted these days.

[tea link]

good night :)

I saw this cool video many years ago.  I thought of this after my mother sent me a video on workers climbing to the top of transmission towers.


Have a good weekend :)

Family is redoing well :)!  Though I'd share the picture.  Back to work.


This is just cool!!

now we need to make Jaws

but seriously, this cool :)

Per Becker's suggestion, I'm putting dots between in portion of the date... still keeping with the 10th of a day for fun.

Today was a long day, still got more work to do.  Currently working on device physics... I went for a very nice long swim followed by dinner and Dr. Who.  I did find the clean room today, but having trouble uploading the photo via drop box off my phone currently.  For some odd reason Davis is really anti place towers in town.  This is a fact, they have placed all the cell towers on the edge of town because the people in town don't want to see the towers... which makes the network here... quit bad. 

I did well on my first project in Digital IC.

end log :)...

Added 2012.03.06.8
I have to correct my pervious statement... there are a few towers located in town [link]... either way... the connections are not very good...

Student's Log... for some reason I have the voice over from James T. Kirk going through my head

since star dates where made up in star trek... but they only had 6 digits... oh well.. I'll just stick with writing year (last two digits), month (two digits), day (two digits), round down(hour/24)... using 0 for midnight...  so right now... it would be 120304.7!

I've just been slowly working on Device Physics homework... to be honest kind of tired to doing it.  Just one more problem to do...


End log...

5th post

lol, still haven't thought of a better post naming process.  I'M DONE WITH PROJECT!!! TIME TO PARTY!!! WOOT!!!  Oh ok... get killed in video game... or go grocery shopping... maybe some Dr. Who... I don't know I'M FREE!!!  Yeah I had a long night... and day.  I still didn't get to go look at apartments.  I'll have to do that this coming monday.

Forgot to add... WOOT FIRST JORNAL!

ELL-2012-0318 'Temperature Characteristics of Schottky Barrier Diodes for Low-Voltage Sensing Applications' has been accepted for publication in Electronics Letters and will appear in a forthcoming issue in the next few weeks

Yiran Li, Li Lu, Dr. Li, and I worked on this

3rd Post

Hello every one,

ITS THAT TIME OF YEAR OF AGAIN AT UofI... oh I miss Engineering Open House...

So just got done with dinner, a little Dr. Who, and oh yeah... woke up form a very long nap.  I was more tired than I thought.

Other good news, :) I finally have lab access and my own desk (this is a picture of the other lab with all the testing equipment... I'll take a picture of my desk tomorrow).  I'll start working out of it tomorrow.  Chairs are comfy, but wheals don't work... probably going to yank some other one tomorrow... lolz no dual monitors ...


I was asked to today... what do you do... when I explained it half a wake to a very nice NI rep, he ask why would you be interested in that... I replied because it is cool... seriously that was my first reply... then I went to explain how it could be useful for some applications (but shez I still haven't narrowed down my research... or started it anew).  I think, at the heart of every researcher... you do it because its "cool."  Lolz, but guess its always good to keep a goal in mind with your work.  I need to be better about pulling my head out of the books...

I've decided to try and write a short blog every day.  If you read it :), thanks, but other wise just need a nice place to vent my thoughts.  Life is quite hectic at times, and not always very convenient when you can vent.  So organizing my thoughts in some sort of manner is probably a good thing.

Well enough chatting on my part.  I've got a project to finish!!!  32 bit ripple carry adder...

2nd POST!

NOTE TO NEW READERS!!!  I've been unusually busy to communicate as normally do... so thought I blog from time to time.

So just got done a bit ago with my Analog exam. Did not seem so bad... but I've been wrong before. Got to start studying for my Low Power Digital IC exam (have it tomorrow)... but for now I'm going to take a short nap followed by Dr. Who. I've been enjoying the new version of Dr. Who. I'm a big Sci Fi fan :D!!!


This looks very lovely ---> link

And I couldn't think of a better Blog name at the time... lolz...

First post

This is my second quarter at UCDavis,

Hello, haven't done a blog in a while, but through this might be kind of fun to do with my mentees. Let me know how this works out... I tried this a few years back with undergrad in an high school out reach program. It didn't work to well, partly my fault. Any ways,

Feel free to post cool music videos, engineering related links, or just random questions,

have a good night,
good luck with the quarter,
