Enhancing Thickness Uniformity of NbO/SiO Multilayers Using Shadow Masks for Flexible Color-Filtering Applications.

Using a stainless shadow mask combined with a magnetron-ion-assisted deposition (IAD) sputtering system, we investigate the surface morphologies and optical properties of microfilms. Optimal color-filter (CF) coating microfilms with niobium pent-oxide (NbO)/silicon dioxide (SiO) multilayers on a hard polycarbonate (HPC) substrate, grown at 85 °C and 50 SCCM oxygen flow, can obtain a fairly uniform thickness (with an average roughness of 0.083 and 0.

Optimal algorithms for the interval location problem with range constraints on length and average.

Let A be a sequence of n real numbers, L(1) and L(2) be two integers such that L(1) < or = L(2) , and R(1) and R(2) be two real numbers such that R(1) < or = R(2). An interval of A is feasible if its length is between L(1) and L(2) and its average is between R(1) and R(2). In this paper, we study the following problems: finding all feasible intervals of A, counting all feasible intervals of A, finding a maximum cardinality set of non-overlapping feasible intervals of A, locating a longest feasible interval of A, and locating a shortest feasible interval of A.
