We fit a Cox proportional hazards (PH) model to interval-censored survival data by first subdividing each individual's failure interval into nonoverlapping sub-intervals. Using the set of all endpoints in set, those that fall are then used as cut points for Each sub-interval has an accompanying weight calculated from parametric Weibull based on current parameter estimates. A weighted PH is with...

We introduce a family of proportional surplus division values for TU-games. Each value first assigns to each player compromise between her stand-alone worth and the average worths over all players, then allocates remaining among players in proportion their worths. This contains new egalitarian as two special cases. provide characterizations this values, well single family.

The tracking of a given voltage in the traditional double closed-loop proportional integral control current power grid simulator has problems such as static difference, delay and oscillation. It is proposed that outer loop inner inverter side adopt quasi-proportional resonance respectively, topology adopts cascaded modular design to establish single-phase model. Compared with proportional-integ...
