Bilevel signal x with maximal local rate of innovation R is a continuous-time signal that takes only two values 0 and 1 and that there is at most one transition position in any time period of 1/R. In this note, we introduce a recovery method for bilevel causal signals x with maximal local rate of innovation R from their uniform samples x∗h(nT ), n ≥ 1,(More)
The aim of this study was to describe and validate a homemade laparoscopic trainer. The abdominal cavity is simulated within a 3-mm-thick stainless steel model. Thirty-four participants were evaluated in a pilot study to validate our model. Participants were divided into experts (n = 19) and novices (n = 15) to perform basic and complex laparoscopic skills.(More)
