Day #267: The problem with exams

test anxiety

I like to take my anti anxiety medication with a light snack thirty minutes before the exam. That way I get the full effect from the meds at about 30 minutes into the exam. The effects don’t last long enough to make it the entire exam, so I split the difference and this gives me the best result since I can’t stop half way and take more. Unfortunately, they don’t help, they never really do. I feel jittery, like I had too much coffee. I can’t remember the things I need to know and screw up even the simplest parts of the exam because I’m more focused on keeping my heart from exploding out of my chest!

Day #266: Pandemic research pressure

Pandemic

Think of research like the post office, nor rain, nor sleet, nor snow, nor pandemic, we will be there working. My dumbass had to make the transition from design to human experimenting the year before a pandemic. I could be safely at home designing cool robots in solidworks, but no we need to collect human subject data and despite the pandemic, I’m feeling the pressure.

Day #265: The lazy goals

prototyping a microcontroller on a breadboard. Random bits of wires can be seen around the black table.

prototyping a microcontroller on a breadboard. Random bits of wires can be seen around the black table.

A “for fun” prototyping project, I thought would be appropriate cover art for the topic at hand.

It’s the end of the term for me. This will be the end of the second year of my PhD program, we have officially started the big countdown to the end of 365 days with (depending on how you want to count) 100 days left, and despite the pandemic, I am making my lazy goals. Mental health is important and my lazy goals help with that, I’ve mentioned lazy goals before, but let’s talk about it in detail.

Day #264: Summer Research

EEG cap

Pay no attention to my messy desk… instead look at the cool EEG cap I set up.

It’s supposed to be a busy summer for me. With the pandemic going on, I’m not sure how that will play out. Since we don’t know yet, let’s talk about how it was planned and then we can discuss how that changed thanks to the COVID-19 pandemic. This may be bad as far as my research timeline… maybe.

Day #263: The Reliable Narrator Fallacy

tell tale heart

True! –nervous –very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease had sharpened my senses –not destroyed –not dulled them. Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell. How, then, am I mad? Hearken! and observe how healthily –how calmly I can tell you the whole story.

Day #262: A Brief Repose

Legion

A project from a few winters ago in my old home. My workshop was so organized!

A friend once described me as, “a maker if there ever was one.” If you ask me, he was being overly kind, but it’s true I enjoy making things. I’m always looking to learn new skills or sharpen old ones. In fact, I’m taking up some “light” woodworking over the summer to do some custom pieces for my home. It will be a fun task, if not a bit tedious and time consuming. I have a list of projects you see, but not a lot of time to do them.

Day #261: On Being a Mentor

Tree

One of the many hats I wear as a PhD candidate is my mentor hat. It’s probably one of my favorite jobs and I get to work with some truly brilliant people from all types of backgrounds. I’ve had the chance to mentor a small handful of people and I always look forward to learning from them and through our interactions, in that sense, it’s a mutually beneficial relationship.

Day #260: The thing about endings

The end

…and thus our mighty hero slay the beast and rode off into the sunset to live happily ever after. But why? Have you ever really thought about the way some stories choose their endings? Our hero goes through live altering and extremely daunting challenges only to brush it off like he caught the wrong bus. Pardon me, but what the actual fuck?

Day #259: The Postscript

Sleep

After awhile you supposedly end up resembling your pet, I think it’s happened. She looks how I feel.

I just want to sleep for fifty years, is that so much to ask for? The deadline is gone whence it came! That does not mean it wasn’t a fight to the end or that there is a weird stillness permeating the house like a calm after a storm. What is it about things ending so abruptly that throws a person into a spiral of confusion?

Day #258: The deadline

Deadline

It’s here.

If you’re reading this, then it is already too late. It’s here, do you feel it? It’s in the house… the deadline. It’s a sneaky dark and evil thing from a time forgotten, but you can feel its presence long before it arrives. It whispers in your ear as you sleep, or did it? Of course, there isn’t anything there for real, right?

Day #257: Tomorrow…

Sisyphus

Well we’re up against the wire now. Tomorrow is the due date for my paper and with it the video I am working on. Will I make it? How much work is left to do? Why am I talking in questions? Find out more… now…?

Day #256: Two days left…

A live shot of me waiting for my data to finish processing

Well here we are and it’s… ♫ the finalllll count dowwwwwn!! ♫ My paper is due sunday at midnight and between the video I need to make, the data that still needs to be processed, and a shitty team mate who has done absolutely nothing to help, well I’ve got my work cut out for me.

Day #255: The impossibility of complete knowledge

Magic-spells

Have you ever tried to learn something and you just can’t seem to get it to stick in your brain? That would be my life, well most of my adult life since I left the Marines. There is just so much knowledge in the world and wrapping my brain around even a fraction of a fraction of a fraction of that knowledge seems to be an impossible task. So what is one to do?

Day #253: A race to the finish

finish line

Well still quite a bit of work to do and some of it was frustrating, but here we are. So let’s run through what I’ve got left to do before the end of the term (ALREADY?!) and talk about the next few posts since I have somewhat of a plan… for once.

Day #252: Dead…line

dead...line

Today is the day, my group presentation is due. Is it done? Well… sort of? Okay not quite, but we’re getting there. My group member still sucks, but since I yelled at him (in a professional manner of course), he’s gotten a little better and has been more responsive, so what’s the hold up? What a great question, let me explain.

Day #251: Deadline tomorrow

deadline

Well the apocalypse can’t stop the gears of education. Tomorrow is our final presentation for the class I am in, so there is work to be done and expectation maximization will come another day. For now let’s give a quick rundown of what I’m working on.

(more…)


Day #250: Maximum Likelihood Estimation

probability

If we are going to talk about expectation maximization (now that I’m done complaining for a bit), we are going to have to introduce the idea of maximum likelihood. It’s going to be very easy to introduce, but it is a very powerful tool in estimating the state of something. Of course, it takes understanding a little bit of statistics, but trust me, if I can understand it, so can you.

Day #249: A stern email later…

angry

Photo of me responding to his email …

I don’t want to jinx it, I really don’t, but I have an update on my group member situation and it isn’t completely awful! I mean, I’m still doing all the work and blah, blah, blah, but I’ve got an interesting story and I hope that things will be better now.

Day #248: A Virtual Conference

background

Every zoom meeting I try to break my PI and get him to laugh, this was my last attempt, still nothing… my work continues.

This will be my first conference since the pandemic and it will be a virtual one. To be completely honest, it wasn’t until yesterday that I was reminded we had one today. It’s a little bit different from our normal routine and I think that is what is throwing me off.

Day #247: The Kalman filter – Part 2

Kalman filter estimate

The Kalman filter converges on the optimal state estimate using noisy measurements and a model that we create.

Okay I lied, I think we can do a better job explaining the Kalman filter, more importantly I have a fun little demo I can share with everyone. It’s not mine, but I like it a lot and it will give you a feel for what the kalman filter does. So let’s get started!
(more…)


Day #246: The Kalman filter

We have 3-dimensions here even though it is a 2 dimensional problem. the third dimension is time, this way we can see the path over the course of the recorded time. Notice there are no units, becuase in this case we were working with synthetic data so the units were meaningless and I did not include them.

This is just one application for the Kalman filter, I estimated a two dimensional position using a random walk model.

Notice there are no units, becuase in this case we were working with synthetic data so the units were meaningless and I did not include them.

Since we’ve been talking a lot about it, I thought it might be a good idea to formally introduce the Kalman filter. This will be a semi-high level introduction (like my knowing your spinal cord series), but at the end of it you should have a relatively good feel for what a Kalman filter is.

Day #245: Fine, I’ll do it myself.

Thanos - I'll do it myself

I will not fail this class becuase of a shitty team member. I will not allow it, I’ve put too much effort and time into this class to do poorly at the last minute because my team member can’t be bothered to do the job he agreed to do. I suppose, this was… inevitable

Day #244: The end of the term!?

end of term

Okay, where the hell did that come from?! It’s almost the end of the school term. WHAT THE HELL!? It feels like we just got started, but my instructor just sent out the final assignment, which is due the last week of school… next week. I’m sort of freaking out right now.

Day #243: Deadlines approaching!

deadlines

It seems like it’s been non-stop for me left and right. I have experiments to do, papers to write, and classes to work on. With the pandemic I was hoping to get a chance to take a break, but nope it seems like I’m even busier than normal. I HAD thought that I was caught up finally when I finished processing some of the experimental data I had laying around, but nope I was reminded yesterday that I had not one, but two major deadlines coming.

Day #242: Experimenting in the time of a pandemic

Experiment-blur

Another day forward in our new normal. I’ve left the house exactly once in the last two weeks and while it’s nice not having to commute to school, I do miss living in a world without the constant fear of catching the virus. What day is it? Who knows, it doesn’t matter anymore. I do have some things coming up though, so let’s talk about experimenting in the age of COVID-19.

Day #241: Modeling the COVID-19 Pandemic

COVID-19

COVID-19

Today is the day. I submitted my super high level explainer video on how I modeled the COVID-19 about  a week ago and I got an email from my professor telling me that it was great (yay) and that she had uploaded it to her labs youtube channel. That means I finally get to share it with all of you!

Day #240: Conferencing at a distance!

video conferencing
video conferencing

Not everyone has access to such luxurious setups.

It’s that time of the year again, well one of two times of the year really (for us anyway). Unfortunately with the coronavirus conferences are better held virtually than in person. While I have mixed feelings about the usefulness of meeting virtually to share our work, I am grateful that there are workarounds, don’t get me wrong, but there are some logistics that make it, well painful and some things that make this worthwhile.

Day #147: First day in the lab

lab

A semi good photo of our lab!

Today is the first day in the lab since break. It was nice to have some time off, I got some housework done, got to spend the bulk of my time sick (not my idea of fun), and best of all I got to see some of the city. It’s been good and now that I’m ready to get back to it, the week is looking to be busy.

Day #146: Back to school!

Back2School

My photo, but not my school, just one I visited.

Tomorrow is the big day, back to school, back to classes. This means that any and all house projects will inevitably come to a screeching halt until spring break (most likely) and it marks the shift in blog posts from life outside the lab to life in the lab. There are a few things I like to do to get ready for classes the day before, so let’s talk school.
