I did a similar project at 18. Needless to say I didn't have enough HW and SW skills to do much since I implemented the most naive form of the TDOA algorithms as well as the most inefficient way of estimating the time difference through cross correlation. I still learnt a lot and it led me to eventually getting a PhD in SAR systems, which are actually beamformers using the movement of the platform instead of an array
There's even "passive cooling" (called thermal mass activation) where you circulate groundwater through the floors/ceiling or concrete walls to cool them down. Ideally combined with a geothermal source heat pump to recover the waste heat dumped to the ground in the cold season
In Switzerland most offices and the majority of houses have exterior metal slat blinds or rolling shutters. Almost all are operated electrically and quite a few are controlled by inputs from wind and sunlight sensors. Since you can adjust the angle of the slats you can significantly cut down solar gains and glare while still providing ventilation and natural light
Count me in the club of failed scientists. In my case it was the geosciences, I would spend hours trying to make all my analysis reproducible and statistically sound while many colleagues just published preliminary simulation results obtaining much more attention and even academic jobs. On the flip side, the time spent improving my data processing workflows led to good engineering jobs so the time wasn't entirely wasted
I've had both hypnagogic hallucinations and night terrors a lot when I was younger, up until my early 30s. They almost disappeared now, which I can't really explain.
For me the worst were the hallucinations, the most recurring one was seeing a dark figure abseiling from the ceiling or from the window, which after waking reveals to be a ceiling lamp or a curtain. It's terrifying stuff while you experience it and I even broken stuff in a desperate reaction of throwing objects to defend against the "intruder"
I'd love for the list to contain location information, something like the country or general area. I feel like I have a lot to learn from a good mentor but it's hard to find then
Ensemble kalman filter (and similar techniques like variational assimilation) are also used heavily in the geosciences to assimilate measurements and model data in order to obtain a "posterior observation" which can be understood intuitively as an interpolation between model and observation weighted by their relative uncertainty (and covariance)
There are plenty of non commercial, non enterprise ELN system. With all their down sides, they are all pretty similar and relatively easy to use (they could use better UI but that's often a problem in research). I think it's almost completely a cultural problem
Yes the technology was there already 15 years ago (minus a nicer UI and a slightly better UX). Researchers despite all the talk about innovation are surprisingly resistant to change
Or you skip the notepad and use a tablet and an electronic lab notebook. I know of a few researcher doing this successfully, but for this to work at scale senior scientists and group leaders need to force everyone in their labs to do the same
Or maybe just adopt the modern solution and use a electronic lab notebook (ELN). I'm a software engineer and we are trying to introduce ELN in our institution, it's not easy to convince researchers of the benefits of reproducibility. People really just use manual methods like "sensible names"
That could describe most of Swiss society as well. Endless discussions on every single topic in order to reach a "consensus". While superficially democratic and beneficial, you do see the limits of this approach when things are serious
the quote is missing what happened after the Platzpitz and later the older Letten train station were cleared: heroin use was decriminalised - not legalised - but only in controlled locations under supervision from medical staff and social workers. It seems that solution helped in multiple ways:
- no people using heroin on the streets
- no overdoses
- drug users became less criminal because they didn't need as much money to finance their use
- the medicalisation of heroin use made it less appealing to new users by removing the rebellious aspect
I wish I heard this advice at the time I was working on my dissertation: everyone just insisted that the right way was to use LaTeX and I just bought into it. At some point so much so that I made my slides with beamers and the animations in TikZ. Clearly I only started being productive when I had real data to present and I decided to switch to Inkscape for graphics and PowerPoint for slides. Leaving academia and being able to write all my documents in word or markdown has been a huge relief.
Indeed if you want to be mobile during an hypothetical societal collapse/apocalypse, few vehicles would beat a (mountain) bike, possibly a slightly older model that uses common parts and doesn't require exotic tools for repairs.
Surely there's more industry knowledge and better tooling/PPE behind stainless steel given the widespread adoption in all kinds of industry? I'd assume the risk for the workers installing it in homes is far lower as the top + sink is usually delivered in a single piece and only needs to be mounted on its support while with engineered stone often the slab is cut to size and reshaped on site
