I wonder how a world without main stream media would look like... Would it be a better place? So much negativity, hidden agenda, pay for play, etc. is present, that one would probably be better off staying uninformed, than reading articles with God knows what agenda.
Is it possible to make like a cheap electric pen using parts from optical mouse? Currently there is Nebo app [1] available for free from Microsoft Store, but it requires touch/pen device. Doesn't work with mouse :(
What is troubling for me is the scale of this. If you could use your phone to map your private house with this library, that is very neat and nice on some level. But I guess in the future everyone will have in their phone app for this (enabled by some additional sensor or via image analysis), and some 3rd party (say some future search behemoth) will collect all this data. That is kinda troubling for me. When you think benevolently, this is very cool. You could have targeted ads for furniture that fit your rooms, and mix and match well etc, but there probably has to be a negative side to this. Just paranoidly thinking out loud :) no need to downvote ...
Is it me, or is this technology really scary? I mean it is cool and everything, but what good can come out of it? On the other hand, bad scenarios easily come to mind, like: "Lets drone him, he can't hide because we have it all mapped, inside out". Am I paranoid?
Analysis of such problems is usually done using numerical electromagnetic tools, based on finite element method (FEM), finite difference time domain method (FDTD), method of moments (MOM) or hybrid methods.
Use of such tools is not a straightforward task, and it takes a lot of effort to create accurate models.
Numerical methods are used because apart from very few problems almost all problems of practical interest (such as microwave ovens mentioned in the article) can only be solved numerically.
This comment just irritated the hell out of me. Who are you to pass judgement on people you don't know? Like we all live in a just universe [1], and everything bad that is part of your life is your fault, including bad relationships with people.
Does anybody know some nice software radio materials? In form of lectures or lab exercises? I was always wondering about background of people which make feats like this. I have a degree in EE, oriented toward telecommunications but would not be able to produce something similar.
Slight off topic. Does someone know a quick way to enter large amount of detailed traffic counts (say around 300 intersections, counted in every lane and every possible turn), and can routing engine and OSM data help? Is there any specialized software that can be used for this type of data entry?
How could this be modified to make something more complex like knitted gloves? Although there are machined knitted gloves they really don't look handmade. In my opinion handmade look increases value.
Thanks for all replies. For some reason I felt that ANN has to be large to perform something useful, and small ~10 neurons ANNs seemed like a toy compared to ~1e6 nets. But, as you pointed out, if it does the job then it is good enough, no matter the count of neurons.
Can someone say a bit about minimum number of layers and neurons needed for structure to be called artificial neural network? I have seen papers with something like 10 neurons (which is very very tiny but authors claim it does the job), while on the other hand there are Google sized ANNs. Thanks :)
Anybody knows whats the catch with MacBook owners plugging their own laptops directly to projector during conference presentations, while others use already available common laptop and just transfer their ppt? It seems a bit snooty :) Although there are benefits, your ppt is not made available to everybody.
Anybody aware of nice, complete video lectures for Operating Systems class? There were lectures from Stanford, but only sessions with profesor, no TA session.
Offtopic, but does someone know a good reference and explanation for OSM tags? A lot of meaning is derived from tags, since the underlaying data structure is just nodes, ways and relations. And since the data is crowd sourced use of tags could be inconsistent, data could overlap and repeat itself. How someone makes a complex project like [1] using data like this?
The models EE use are simplified, drift and diffusion current and electron and holes with their different mobilities and energy levels. Math apparatus used here, and strictly related to statistics, is limited to averaging, I would dare to say.
Thanks! I had a course at uni named Probability and Statistics, but since it was first (and only) course in EE curriculum it was oriented toward probability, and Statistics was an afterthought (I only remember simple linear and multilinear regression). That is probably the main reason I only see curve fitting everywhere :)
Thanks for the comments. I am not familiar with WiFi protocol, so I didn't know about amount of time/power antenna spends receiving/transmitting, and how the sniffing works (ie it seems to be entirely passive operation?). My karma has gone to hell ;P
If my evil :) speculation is true, the camera sensor is just picking up mechanical vibrations from environment (coming through air, tripod etc.) and encoding them into video. There is no proof that the bag of chips is vibrating (they even say that the vibrations are not visible on footage). They are extracting something from video, but that something may just be spuriuos pickups by equipment, and not related image/video of bag of chips. Thus it would be just a silly way to measure spurious mechanical vibrations.
Thanks. However, there is still a possibility that mechanical vibration is coming to the video sensor through some path (floor+camera tripod), and affecting the video. After all mechanical vibration is affecting the potato chips. Why is it so impossible to affect video sensor? Especially in the sensitive high speed camera? Let the downvotes begin :)
I know, but I still wonder about level of soundproof/mechanical vibration and the level of mic and camera sensor isolation VS level of optical vibration. In addition sound can travel many different paths since it is mechanical vibration, and traveling through sound proof glass is not the only path. Anw cool project.
