In this paper we show that a number of NP-complete problems remain NP-complete even when their domains are substantially restricted. First we show the completeness of Simple Max Cut (Max Cut with edge weights restricted to value 1), and, as a corollary, the completeness of the Optimal ...

As an example, a simplified mathematical model of the human head-cervical spine system is presented. In a numerical experiment the model is used to analyze motion of the head–neck during rear-end impact which may lead to whiplash injury. The obtained results are compared to literature data. ...

3.2 Multibody model of cervical spine It is not the purpose of this section to present a novel and complete (in some measure) model of the cervical spine. Actually, the multibody system discussed below has a two- dimensional, simplified nature. However, despite its limited complexity, the ...
that even when the theory is positive (that is, it does not contain constraints), finding a minimal model is [Math Processing Error]-hard [8] (note that positive theories always have a minimal model),1 and checking whether a model is minimal for a given theory is co-NP-complete [7]....
