Emergency Brake Assist would help if the van was equipped with it. Swerving at the last moment and without warning would not be possible because EBA would activate brakes earlier a…

Calculation of battery capacity one can build for 34B 0.3k$ per 1kWh of battery storage [1] (0.3$/Wh) Battery capacity = 34B$ /(0.3$/Wh) =113.3GWh (1G$=1B$) The 34B battery capacit…

This list should also include Charles Stross Laundry Files series. The concept of high math being a gate to higher dimensions and effectively magic powers provides great setting to…

It looks like availability of good quality training sets will be a stumbling block for LLM use in Verilog chip design since pretraining with other programming language corpus is no…

Hardware function implementations deal with multidimensional design space metrics: performance (speed), power and area. These should be taken into account in any work intended for …

Poland has developed and is producing their own MANPAD system initialy based on Soviet design. They supplied significant number of these to Ukraine where it performed well. https:/…

From the link it looks like it had many changes implemented to improve safety: The EPR is a so-called “evolutionary” reactor, that is to say that its design is based on that of exi…

Same here: Honda CR-V 2020. It uses single lens (so not a stereoscopic vision) and radar. Never did it brake hard, only warning and few times brake pretension. It will occasionally…

Possinly by replacing fat tissue with muscle? I guess it will depend on protein vs sugar and fat content in the diet.

One notable exception is Verilator which is growing fast and competes welll with commercial Verilog simulators ( https://github.com/verilator/verilator ) It has industry support no…

At deep submicron technologies even analog circuit layout must be done by CAD tool in order to meet DFM (design for manufacturing ) rules. These rules (due to interference effects …

It depends on criteria. For example, USA early vaccination ramp up is second to only United Emirates in the world. Taiwan was late in this particular aspect and quite panicked when…

I'm in Taiwan and was here for a whole pandemic. Article is spot on but this response efficiency, visible now, was acquired over last 2 years of improvements. Taiwan had a luxury o…
