An FPGA implementation of a multilayer perceptron neural network is presented. The system is parameterized both in network related aspects (e.g.: number of layers and number of neurons in each layer) and implementation parameters (e.g.: word width, pre-scaling factors and number of available multipliers). This allows to use the design for different network(More)

Academic computing services provide computing for student instruction and faculty research. Recently, academic computing centers have taken on the task of providing On-line Public Access Catalogs for libraries. Besides serving a new audience, there has been a paradigm shift. The On-line Public Access Catalogs are indeed production systems and understanding(More)
In hexaaquanickel bis(2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) dihydrate, [Ni(H(2)O)(6)](C(5)H(3)N(2)O(4))(2).2H(2)O, the nickel cation is coordinated by six aqua ligands and only associated with the two orotate ions through hydrogen bonds. The structure is isotypic with the magnesium and zinc analogues. The metal cation sits on a(More)
Reduction of 1,2-closo-C2B10H12 followed by treatment with [RuCl2(p-cymene)]2(p-cymene = C6H4MeiPr-1,4) affords the 13-vertex ruthenacarborane 4-(p-cymene)-4,1,6-closo-RuC2B10H12, characterised both spectroscopically and, in two crystalline forms, crystallographically. Although asymmetric in the solid state, having a docosahedral cage architecture with cage(More)
