Thanks for finding the paper. Sucking almost 3A out of the battery, it's not going to fly very long, but that's also a fairly inefficient power converter design. There is lots of room for improvement.

In theory. It could be made with no moving parts and steered via thrust vectoring by varying the location of the negative voltage. Lightweight high voltage equipment like that is very expensive to make at those reliability levels currentl

Code sharing is actually really good in visual languages if done right because you are forced to have well defined inputs and outputs for your nested structure. Search is getting better and is not bad in Simulink. Pattern matching would b

I wrote pong by encoding the ball position as a continuous complex variable and used a star chart (I-Q) with minimal persistence as the output. The paddle inputs were just variable sliders bound to a limit threshold equation. Ball motion w

Some of your complaints come from the fact that LabVIEW is pretty niche. It would need at least an order of magnitude more developers to see numbers like C/C++. That's why you're not finding much online help. There is also

I think it really depends on how you define a programming language. Simulink can generate a variety of codes from models, the most common being C as you mentioned, but Simulink models can also be compiled into an executable using the Real-

Agreed. Simulink is an extremely serious visual programming language that powers many of our modern high technology. Spacecraft and the like. The authors point on assuming reduced complexity makes me think that he doesn't understand

I think you are confused. To get a linear amplifier, you operate your output transistors in a state of Saturation. This gives a linear transfer function to the drain based on the Gate to source voltage and you use a method of choice to hol

Sure in music circles, but National is pretty big in DSP circles and if I just search NI in google, National Instruments is the first 5 results followed by a news story followed by Native Instruments. If you go to NI.com, that's Natio

I think you might want to disambiguate a bit. When people say NI, they are almost always referring to National Instruments, not Native Instruments. Especially considering that both deal in virtual filter implementations.

N connectors are robust, so they get used heavily in military applications and that scale of production makes them relatively cheap and the mil-spec they are produced to ensures that you don't get moding until 20 GHz. They are also hu

The characteristic impedance of a cable is distributed and depends on things like the spatial relation of the connector to the shielding, other internal conductors, and what the cable insulator is made of. Changes in these parameters resul

The power required to track the entire human industrial supply chain using a block-chain algorithm would be so incredible that it would quickly dwarf any possible gains. It would in fact be a significant percentage of all total power consu

Well, part of it is just the sheer scale of US education institutions. If we define University students as everyone enrolled and seeking a Bachelor's or higher then the number of University students in the US is greater than the total

Trees are quiet good at scattering RF mostly do to the water in them, their density of leaves/needles and the random orientation that they grow in. This leads to significant attenuation of the signal even if it isn't absorbed by a

My immediate problem with this study is that they personally selected a sample of 60 damaged trees near radio transmitters to compare to a selected sample of healthy trees away from radio transmitters. The conclusions is effectively built

The article is incredibly disingenuous. The first paragraph is the typical goalpost of proving a negative. This is a common tactic of scare groups opposed to something. See also vaccine denialism demanding that it be proven that it is saf

To me it sounds more like the device received too much current on it's driver circuit and shut down to prevent damage to the device which is exactly what an implant should do since shutting down just means a trip to your doctor to get
