Random Outings

Just thought I post some of the fun stuff that I’ve been doing in North Carolina. I’m actually back home for vacation, but it’s a short vacation. I’ll post about the family road trip I took with my parents in a later post. As the title indicates, this is just highlights of random fun outings I’ve had while living in North Carolina. Start by watching the video below.

Power System State Estimation using a Direct Non-Iterative Method

Today I share a paper that I’ve been working on for the last 3 years. This is the first research journal paper that I’ve ever published, so it is a personal milestone. I post it here just to show that my PhD studies weren’t completely unproductive, given how most PhD students usually have a few journal papers on their CV when they graduate. The topic of this paper is the major topic in PhD dissertation, and I also have an earlier conference paper on this topic. It’s been a long time coming for this paper, and I’m glad we finally got the paper published. Hopefully I’ll have a few more publication as I continue to work in the power industry. Read below for the abstract and link to access the full paper.

Replacing My Car’s Engine and Cabin Air Filters

Today I just replaced my car’s engine and cabin air filters, because they were due for replacement according to the maintenance booklet. This is the first time I did any of the maintenance myself on my current car. I had replaced the engine air filter on my old car, but my current RAV4 is nothing like the ML350 that I had, so this is a new “experience”.

Long Time, No Post

I realized I haven’t updated this blog for several months. Just posting to show that I’m still alive and kicking. It’s not that I have been working so hard that I didn’t have time to post, but I just haven’t done anything that I thought was worth posting on its own. This doesn’t mean I haven’t been doing anything. I try be out and about on the weekends, especially now that the warmer and nicer weather of spring is upon us here in North Carolina. I visited a lot of the local parks, and I’ve tried a number of restaurants. I don’t know if I can be classified as a foodie since I don’t think my taste buds are very discerning, but I like trying new restaurants and I love delicious food. I haven’t really traveled outside of the area I live… at least not for fun. I had business trips, but I can’t really do touristy stuff when I am on the clock.

Below are some photos of some of the fun stuff I’ve done over the last couple of months.

A Low-Rank Matrix Approach for the Analysis of Large Amounts of Power System Synchrophasor Data

I was randomly looking at my Google Scholar account and saw that a conference paper with my name got published, and so I’m sharing the paper on my website. The paper was for the 48th Hawaii International Conference on System Sciences, and it’s something that I worked on when I was still at RPI. I only helped with a section of the paper, and hence my name is pretty far down the author’s list. Still, it’s never a bad thing to have more items to put on my publications list, and a sincere thank you to my talented co-authors for their hard work. The topics covered in this paper is actually something that I find very interesting. The ever larger amounts of power systems data produced by synchrophasor devices produces problems for analysis and storage, and the ideas outlined in this paper have potential in alleviating these issues. Read below for the abstract and link to the full paper from the conference website.

Another Year Gone By

2014 has passed, and here we are at 2015! 2014 has been a pretty eventful year for me. I finished my PhD degree and got a job, and that entailed a move from upstate NY down to North Carolina. That’s a big change for me, and I’m still getting used to life after school. It’ll take time, but the future looks bright. My New Year’s resolutions is to make some new friends in NC, get better at my job, and to lose a couple of pounds. Compared to when I graduated in May, I have lost a few pounds since moving to NC, but I can still stand to lose some body fat. I also probably gained a few pounds over the holidays too.

Holiday Season

The holiday season has arrived and we are only a few days from Christmas. I’m looking forward to a short vacation in a few days. As a new employee, I don’t have many vacation days, but combining my vacation days with Christmas and New Year gives me a week or so of not having to work. No more spending a month back in Metro Vancouver during the winter, but a break is appreciated nonetheless.

Fall Hiking and Exploring Round-Up

It’s been about three and a half months I’ve moved from Upstate NY down to the Triangle region of North Carolina for work. I’m still trying to get used to my new job and surroundings. Having a full-time job means my schedule is less flexible than when I was a student, but I always try to go out hiking and exploring on the weekends, and here is just a round-up of what I’ve been up to. I’m not going to write much and let the pictures do most of the talking.

Taking Stuff Apart (and Putting Them Back Together)

As I posted a little while ago, my iPhone 4S stopped working. I got a new phone, but I still wanted to see if the iPhone was salvageable, so I spent a few bucks and bought some tools on Amazon to open the 4S up to take a peek. Since the phone is dead, I might as well take a look inside for the slim chance that I can find where the problem is. Given how popular iPhones are, instructions on taking the phone apart are easily found online. I followed this set of instructions and managed to remove the logic board from the phone. The iPhone 4S and all the innards I took out can be seen in the photo below. The parts are tiny, but the disassembly is doable with a little bit of patience and organization (so you don’t lose the screws). Unfortunately, I couldn’t find the problem, and chances are the phone needs a new logic board, so I just put the whole thing back together and stuff it on a shelf for now. It was a good little exercise.

Speaking of taking stuff apart and then putting them back together without making any repairs, I also took my washing machine apart. The last couple of weeks I noticed that the washer leaves soggy clothes after the spin cycle. The tub spins as far as I could tell, so I took apart the washer to check for clogs in the hoses. I have a pretty common Kenmore direct drive washer, so disassembly instructions were easy to find. The process is actually pretty easy. I went as far as taking the pump out to check for clogs, but I didn’t find anything. The funny thing during the whole process was that I was able to take the washer apart and take the hose clamps off with a small pair of pliers, but then I found that I couldn’t put the clamps back on with my pliers. I ended up having to buy a pair of tongue-and-groove pliers the next day in order to put the hose clamps back on. Below are a few pictures of my washer with its cover off.

Travel Log New Theme and Content

I spent some time in the last week or so updating my Travel Log website to a new theme. To give some background, the Travel Log is a Chinese language website that contain travel dairies written by a relative. The new theme is reminiscent of the old HTML website I made for one of the older series of travel logs before I converted the whole site the WordPress. In addition, I also uploaded my relative’s new Caribbean cruise travel log onto the site for those who are interested.
