i'm retiring that jacket. it was nice back in the day, the super-thin goretex that north face only sold for a year because it wasn't durable enough.

someone found the phone tho, and called up the last number on it (my gf). my faith in humanity is restored. temporarily.

:D

woohoo, phone is back in my paws. actually, not quite: i got the original one back last night, but its daytime nap in the mud and wet leaves caused part of the touchscreen to freak out. a trip to the apple store later i now have a shiny, new replacement phone.

i'll try not to drop or lose this one.

:D

i hit a gas mileage record on my recent trip record-

83 km per gallon.. or about 55mpg over a 100mile stretch... well, it was pretty much 100 miles of steep downhill roads, from 12k ft to sea level :biggrin:

on the flat highway, at 90 kmh, got a very respectable 40mpg (actually a bit over)... but drops into mid 20s at 150-160km/h.

altitude loss is cheating! it would be interesting to back-of-napkin the amount of potential energy in a gallon (liter, whatever) of gas vs. the potential energy of a 1200 kg mass moving down 4500 meters...

two phonepics from today, fog in the morning and sun in the afternoon. the skybridge in question is about 9 stories above the ground, as is the one from which i took the shots. ohsu is a maze of hospitals on a hillside, with bridges between buildings every which way. sometimes you'll exit the building on one side at "ground level" and look out the window on the other side of the same floor and find the ground hundreds of feet below. quite cool.

there also is a tram that heads down to the waterfront. more pics of that later this month.

morning fog, this at OHSU in portland, of course



afternoon sun

well, given the yaris has a relatively high 10.5 compression ratio and vvti dialed for fuel economy, i´ll assume it to rank high among IC thermal efficiency. i guess around 30% would be a rational guess.

there are about 130 million J in 1 gallon of gas, at 30%, usable mechanical energy is about 36 million joules.

potential energy at 4500m is about 53 million J.
so roughly... the mgh energy is like an added 1.5 gallons to the almost 2 gallons used over the 100 miles.

100/3.5 equal around 28 miles per gallon adjusted to elevation loss.
pretty reasonable, given its a very twisty stretch with some hard braking needed (so much my brakes faded and i had to stop for 20 minutes).

I thought moving the gearbox to the rear was to help weight distribution. Wouldn't moving it back tend to increase the rotary moment of inertia?

You're right, polar moment is sacrificed for distribution, at least in theory. However, the GT-R's transaxle seems pretty far forward, at least in comparison to, say, the pendulum-like weight of a 911's engine. But yes: it probably won't be a great autox car, being too big, too heavy, and, yes, too well endowed in polar moment. It sure isn't an Elise, for better and worse.

jessica and i headed out to my parents' place in coos bay this weekend. the coast is nice, even if foggy and windy at times. in editing this bunch of pics i decided to violate my "sacred" preserve-the-3:2-aspect-ratio rule, and i think it worked for the sea shots:

it snowed in seattle yesterday, first of the season. bike riding season is most definitely over, even for the purposes of commuting in to my lab, i fear.

the lab isn't on the same campus as the hospital, which is a 4 mile mostly downhill spin with about 70% on a dedicated bike path. instead, the way to the lab is a bit further, and is on 30 mph arterials with parked cars, potentially icy roads, stoplights, and many, many hills.

:(

the bus it will be.

in other news my residency interview season starts tomorrow as i fly out to yale. also on the queue at this point are UT Houston, tufts, brown, ohsu (portland), virginia mason (private hospital in seattle), and sacred heart (private hospital in spokane). wish me luck :D

yale: awesome. i would definitely go back to a place like that.

UT Houston: not so awesome. huuuuuuuuuuge medical center (quoted as having 74,000 employees! yes.). good faculty. i'd go there were it not for the city and the weather, respectively strip mall hell + traffic and 80 degrees x 80% humidity... in december.

post #3502. dude.

even with interspersed ridemonkey- and NASIOC-surfing, my brain is about to explode: i _think_ i have viable, processed data on the 3 year olds' brains, nicely partitioned into grey, white matter and CSF, smoothed appopriately to make the noise/variance more evenly distributed, etc. etc.

however, now the question is how to do the statistics (which tests, and then how to implement these tests given the software i'm using [matlab/SPM/VBM5]). i've basically been absorbing material all day, and i'm not sure how much more i can take.

one way ANOVA to test for volume changes without correcting for total intracranial volume?

one way ANCOVA with the intracranial volume as a covariate? wouldn't this analysis factor away what we're looking at if the volume changes in autism are not particularly localized to a given brain region? (yes, but who would publish a paper if it didn't control for this?!)

what about multiple comparisons? Bonferroni? or is that too rigid, will it throw away all of our power?

should i be concerned if my design matrix is rank-deficient? ("row echelon form" brings up hazy, not-always-positive memories from the past)

4th year med student, slowly going crazy. full time in a lab in the neuropsychiatry imaging group for a bit. autistic children vs. controls vs. developmentally delayed. volumetric analysis of MRI brain data at 3 yrs, 6 yrs, 9 yrs of age in each group. matlab. matrices used to specify contrasts (ie, if you have two groups and you want a t-test you specify a matrix of [1 -1] to compare the two).

thankfully no finance involved! ANOVA is used because we're looking at variance like the financiers, only our variance is in the amount of grey matter at specific locations in the brain.

Crystal had tons of snow today, btw -- cashed in some warren miller free ticket passes that some friends passed my way. unfortunately it still was cascade snow, even if closer to powder than concrete. i hurt.

How are you liking Seattle Toshi?
i both love and hate seattle.

seattle pros:

- solid xc biking every which way, with real mountains (attention, east coasters! :D)
- many ski areas nearby: snoqualmie/alpental (50 minutes away), stevens pass (2h), crystal mountain (2h), mt. baker (2.5h), white pass (2.5?)
- vancouver, bc is 3h away (assuming off hours at the border crossing), and whistler is 4.5h in the summer
- natural beauty: puget sound, greenery everywhere, the Olympics on one side, the Cascades on the other, Mt. Rainier, all of which are visible on a clear day from seattle itself
- relaxed culture without going completely to pot: one can wear jeans and a fleece to the seattle symphony without raising an eyebrow, yet the symphony itself is flourishing. people like their arts, and there are a ton of local groups to play in for those not doing it for a living...
- excellent restaurants: see my list here http://www.xanga.com/toshiclark/532781876/seattle-restaurants.html
- good public transit provided that you live in a populated area. i can take a commuter bus from 5 blocks from my [shared] house straight to the business district downtown, to the hospital area ("first hill", or "pill hill" in some circles), or to the university district. light rail from downtown to the airport should be coming in 2009, but as it is it takes me about an hour on two buses to get from my house to the airport, compared to ~30 min on a good day in the car.
- drivers are very polite for the most part, and will let you merge, etc.
- many young and young-ish people actually get outdoors here. REI's flagship is in seattle for good reason, and it's nice to see many other people heading up to ski, to bike, to kayak.
- summer weather is perfect. blue skies, green trees, fresh air.

seattle cons:

- no legal DH in the whole state, basically, unless you head all the way out to the east side (cle elum or spokane, even). Oregon and BC put washington to shame in this regard, and this is a large part of the reason why i stopped dhing when i moved here from portland, oregon.
- traffic is HIDEOUS. in the grand scheme i'm sure it's simply on par with other big cities, but one can easily spend an hour trying to get from one side of the city to the other (especially across the two bridges that span lake washington, splitting seattle from the "east side", redmond/bellevue/kirkland/issaquah). i basically try to never drive during rush hour.
- it does rain, and it does get quite dark and gloomy during the winter. it's basically overcast from december through march: one year we had 99 straight days when it at least drizzled. seasonal affective disorder ("winter blues") is pretty common, and is no joke if you are affected by it.
- ski areas are crowded, and the xc biking trails closer in to town also get a large crowd after work and on weekends.
- there are a bunch of heroin junkies, meth heads, and mentally ill people living on the streets in the downtown/pioneer square area. pioneer square is a place where tourists go in the day, and where college kids go to hook up in clubs at night. i try to stay away after a nasty incident where a junkie broke into my car and stole one of my trumpets...
- housing is quite expensive here. not boston, new york, or bay area levels, but the median home price within seattle proper is $500k nowadays, and living outside the city sets you up for a hair-wrenching commute if you're not careful.

are you considering moving out here MMcG? if so, in what part of town would you work?

i want this, the Aptera Typ-1:
more info, and a projected release date in 2008 (cali only -- i'd make the trip for one :D): http://www.popularmechanics.com/automotive/new_cars/4237853.html?page=1



single sided swingarm:



drag coefficient of 0.11! (frontal area not specified, but looks low)



the dashboard of the future, admittedly kind of amateur-set-design-ish:



15.9 cubic ft of cargo space:



plug in to charge:



and the price:

popmechanics said:
Fambro says Aptera only needs to sell 300 vehicles to make the company profitable. So far the company has over 580 orders for the $27,000 Typ-1 e and the $30,000 Typ-1 h. Pilot production is set to begin with 30 Typ-1 e vehicles next year, though eventually Aptera expects to build 2000 vehicles annually. Sign us up for a long-term test.
(Typ-1 e is all electric, 120 mile range, Typ-1 h is plug-in series hybrid, 300 mpg quoted. note that in my original post the figures were transposed. at 300 mpg this would be more efficient than an all-electric car, which shouldn't be possible since Li-ion battery packs are more efficient than internal combustion engines/generators, so i think the math is incorrect.)

for the mathematically minded, here's an excellent lecture by Peter Lu (harvard physics grad student) that ties together Islamic architecture, quasi-crystals (structures with "forbidden" 5-fold symmetry) and Penfield mapping of the plane...

http://media.physics.harvard.edu/video/index.php?id=Peter_Lu_12_03_07.flv

it's actually really accessible, and fascinating material, most of which is presented visually.

also, if anyone is interested in watching (or listening to) an audio or video podcast series of a harvard lecturer doing one of the most highly-rated undergrad courses, on Justice, then PM me and i'll send you a link that you can paste into iTunes.

here's peter lu's homepage btw: http://www.physics.harvard.edu/~plu/

i headed up to stevens pass today with more or less the usual microsoft crew, only 5 short days since tiring myself out in the wet, heavy powder at crystal. i should have learned. it was a veritable blizzard on the hill, with what looked to be about 6" falling over the day, as judged by the buildup on my car.

unfortunately, the combination of poor visibility, tired early-season legs, insufficient breakfast, and paltry sleep led me to feel awful to the point that i considered calling it a day at noon. my mood was so foul internally that i actually was mulling over selling my ski gear and renouncing the sport. food and warmth revived me, however, and skiing was redeemed in my eyes after some turns in the powder after lunch.

although the skiing was ultimately good, the real fun began when i returned to my car. it was buried, as was every other car in the lot. even with winter mud + snow rated tires mounted i foresaw little chance of my light, rear wheel drive RX-8 freeing itself from the morass.

i was right.

it took a solid 80 minutes from arriving at the car post-skiing to exiting the parking lot. along the way much pushing, rocking, shoveling, and, ultimately, being towed with a giant hook and rope by the resort's F250 recovery vehicle was undertaken.

i think this may well be both the last time i willingly ski at a resort on a weekend in the height of holiday madness (too many people! agh), and the last time i drive my RX-8 to a ski mountain. hmph.

now i want an awd hybrid. been reading all day about the ford escape hybrid and the toyota highlander hybrid. it'd be nice for a manufacturer to come out with a hybrid that's designed from the outset as one, has great mileage, has awd, is practical (no sloping rooflines or rear quarter panel beltlines that swoop up for poor visibility).

in all my mulling over of things i also decided that diesel is out. even 2008 models of diesel cars (VW, Mercedes) do HORRIBLY in terms of emissions as rated by the US govt: http://www.epa.gov/greenvehicles/

yes, i'm fickle.

:D

:D
and here's my mental wrapup of all this thought, as posted on my blog:

xanga.com/toshiclark said:
life as a series of linear equations

i tend to see life as a series of linear equations.

Gheos, a game i picked up a few months ago, involves optimizing multiple variables simultaneously, of wheat, cups, temples, pyramids, armies, and coins. in photography the product of the aperture, shutter speed, and film sensitivity must equal the exposure that a scene's lighting dictates. even the research that i do involves linear algebra, too, in that scans and conditions are laid out as a matrix, and statistical tests are defined by creating a row vector and doing matrix multiplication.

given this tendency, my longstanding obsession with cars, and the unfortunate reality that i can't shut my brain off even when i'd like it to be at rest, it shouldn't surprise anyone in the slightest that the cogs and gears in my head have been spinning of late on the topic of transportation.

it's particularly hard to find an answer to the question of what-car-is-right-for-toshi because what i want out of it is contradictory:

i want something cheap to own, yet have the self-imposed restriction that it meet strict, modern emissions standards, ruling out old and even older cars.
i want something that can hold its own on the racetrack -- literally, no street racing here! -- yet be at home on snowy mountainsides and remote trailheads.
i want something flashy, yet i want it to be discreet.
i want something that's lean and true to its purpose, yet can do it all.
i want something that no one else has, yet i want it to be easy to repair and maintain.
i want something that reduces our dependence on foreign oil, yet doesn't force me to be a martyr.

currently i'm in a Mazda RX-8. it's not particularly cheap to own or insure, is decidedly not at home in the snow, likes to high-center itself on doubletracks, isn't discreet, can't hold much inside or especially in the miniscule trunk, and isn't particularly frugal on the premium blood-oil. on the other hand, it was designed with a singleminded emphasis on being as light as possible, is beautiful, meets the reasonably strict Bin 5 federal emissions standards, handles wonderfully, is sufficiently rare, has a friendly local dealer, and performed admirably even when packed to the gills on the road trip this summer.

unfortunately, the car makes me feel guilty: for shortchanging my outdoor side, having more or less sacrificed skiing and biking on the altar of on-road performance; for driving a car that gets 23 mpg on the freeway on a good day; for driving something "nice" when i should probably be buckling down and preparing to live an ascetic life as an intern, starting out in a new city with jessica.

i'm over that stage that many are stuck at when i mistakenly thought finding the right car would make life itself better. for that matter, substitute any material good for car and you describe a whole host of lost souls above which i like to imagine myself.

on the other hand, that i acknowledge that a car can't fix all of life's ills doesn't mean that i should stop looking for something that fits my needs better. it's just that nothing seems to quite fit. in my head i've gone over a million different alternatives: the Prius would be perfect if awd; the Ford Escape Hybrid's mileage is somewhat disappointing; the Toyota Highlander Hybrid is expensive and thirstier yet; the diesel VWs and Mercedes have horrible emissions if good fuel economy; full electric cars aren't commercially viable yet and aren't suitable for long distances; no major manufacturer sells plug-in hybrids as of this day, let alone one that would satisfy my conflicting desires; electric motorcycles are almost there in terms of their attributes but have the downside of, well, being a motorcycle -- i like my skin, the warmth of the car's heater, not to mention the ability to carry sporting equipment...

it's kind of an odd and trivial thing to be obsessing about, i know, but i don't necessarily choose what my brain will chew on next. that's the downside of being me. suggestions are welcome, by the way, but expect a terse rebuttal to each unless it's something truly novel.

at the link below is a zip file containing the first 4 of 5 parts of Bach BWV 1004, Partita #2 in D minor. the performer is Thomas Zehetmair, and this is from John Stewart's set of CDs that i ripped back during those Mus51 days.

http://download.yousendit.com/30AFC8F070E072AB

also in the archive is a messy set of sheet music for that same music. sorry about the visual clutter -- it was taken from a site that intended to be played on guitar (the sacrilege!).

i find it very satisfying somehow to follow along in the score (does it still count as a score if a single part?), as the later movements are just fast enough to push the limits of my sightreading/"mental sightsinging" ability. i'm not sure how you people who routinely play complex and fast parts on piano and violin stack up in this regard, but it takes much concentration on my part.
