I consider a model where a principal decides whether to produce one unit of an indivisible good (e.g. a private school) and which characteristics (emphasis on language or science) it will contain. Agents (parents) are differentiated along two dimensions: a vertical parameter that captures their privately known valuation for the good (demand for private education), and an horizontal parameter th...

In this paper we demonstrate that the distributional laws that relate the number of customers in the system (queue), L(Q) and the time a customer spends in the system (queue), S(W) under the first-in-first-out (FIFO) discipline are special cases of the H = AG law and lead to a complete solution for the distributions of L, Q, S, W for queueing systems which satisfy distributional aws for both L ...

Road departure is one of the main causes single vehicle and frontal crashes. By implementing lateral support systems, a significant amount these accidents can be avoided. Typical are normally occurring due to unintentional lane where driver drifts towards across line identifying edge lane. The Lane Support Systems (LSS) uses cameras “read” lines on road alert if car approaching lines. Anyway, d...

A novel spectral method with variable transformation, the adaptive Hermite-Gauss decomposition method (A-HGDM), has been developed and applied to the analysis of three-dimensional (3D) dielectric structures. The proposed method includes an optimization strategy to automatically find the quasi-optimum numerical parameters of the variable transformation with low computational effort. The techniqu...
