The length function `q(r, R) is the smallest length of a q-ary linear code of covering radius R and codimension r. In this work, by computer search in wide regions of q, we obtained short [n, n− 4, 5]q3 quasiperfect MDS codes and [n, n− 5, 5]q3 quasiperfect Almost MDS codes with covering radius R = 3. The new codes imply the following upper bounds: `q(4, 3) < 2.8 3 √ q ln q for 8 ≤ q ≤ 3323 and...

A novel, efficient, time-saving and reliable radiolabeling procedure via nucleophilic substitution with [(18)F]fluoride is described. Different radiolabeled aliphatic and aromatic compounds were prepared in high radiochemical yields simply by heating of quaternary anilinium, diaryliodonium and triarylsulfonium [(18)F]fluorides in suitable solvents. The latter were obtained via direct elution of...

This article presents two new, reconfigurable multifunction floating-gate circuit to produce either the INVERTED CARRY function for a FULL-ADDER, an INVERTER, or two-input NAND or NOR gates. The circuits contains two MOSFETs and three or four capacitively coupled input signals. SPICE simulations are shown, demonstrating the principal operation, together with preliminary measurements indicating ...

We consider the issues of noise-to-signal estimation, finite sample performance and hypothesis testing for the nonparametric efficiency estimation technique proposed in Cherchye, L., T. Kuosmanen and G.T.Post (2001) 'Nonparametric efficiency estimation in stochastic environments', forthcoming in Operations Research. In addition, we apply the technique for analyzing European banks. 5001-6182 Bus...

In the movement of freight across the supply chain, terminals play an important role as points of transfer between different modes. The location of terminals is one of the most crucial success factors bearing directly and indirectly on the main stakeholders involved including policy makers, investors, terminal operators, freight operators, and the local community affected. There have been sever...

In this paper, a modeling technique for CMOS gates, based on the reduction of each gate to an equivalent inverter, is presented. The proposed method can be incorporated in existing timing simulators in order to improve their accuracy. The conducting and parasitic behavior of parallel and serially connected transistors is accurately analyzed and an equivalent transistor is extracted for each cas...
