Computer scientists have shown that electronic voting machines are easy to hack.
They are prone to miscounts — including "vote flipping," in which votes for one candidate are recorded for another — and computer scientists have shown how easy it is to hack these machines and change the vote totals.
However, as our computer experiments have shown, this approach can be computationally demanding and slow.
In [6, 7, 9], computer simulations have shown that this method can produce more accurate DOA estimation results than the open-circuit voltage method.
But now two computer scientists have shown that the whole system may be only 33% less efficient than if data delivery were perfectly optimized.
Studies of computer software have shown its potential to enhance phonological awareness in children with reading difficulties, but few have examined its use with young children.
Computer simulations have shown that redesigned digital systems incorporating the PSO-derived digital controllers have better system performance than those using conventional open-loop discretization methods.
Even though computer simulations have shown that solid surfaces may induce pronounced density variations in a liquid, the latter rarely extend beyond three to four molecular diameters away from the surface (e.g., [43]).
Computer models have shown that the early solar system was a tumultuous billiards table, with dozens or even hundreds of planetary building blocks the size of Earth bouncing around.
Furthermore, computer simulations have shown that the overall closed-loop system with an HRN controller achieves good asymptotic tracking performance which proves the feasibility and effectiveness of the proposed control scheme.
Our experiences with a virtual computer laboratory have shown that hands-on activities which are designed based on a prescriptive, step-by-step approach do not always achieve the expected learning outcomes.
