cu-mo and cu-ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. the effects of process parameters such as film thickness, annealing duration and temperat...

In this paper we introduce the notion of fractal codimension a nilpotent contact point $p$, for $\lambda=\lambda_0$, in smooth planar slow$-$fast systems $X_{\epsilon,\lambda}$ when order $n_{\lambda_0}(p)$ $p$ is even, singularity $s_{\lambda_0}(p)$ odd and has finite slow divergence, i.e., $s_{\lambda_0}(p)\leq 2(n_{\lambda_0}(p)-1)$. The generalization traditional slow-fast Hopf Li\'{e}nard ...

The paper presents an approach to find contact points on an object surface that are reachable by a given hand and such that the resulting grasp satisfies the force-closure condition. This is a very common problem that still requires a practical solution. The proposed method is based on the computation of a set of independent contact regions on the object boundary such that a finger contact on e...
