Accés obert
A theoretical analysis of the double-slug transmission line tuner and the microstrip discs is developed based on two separate models: a distribuited impedance transforming model and a lumped shunt susceptance model. No ...

A branch and bound approach for the capacitated plant location problem using cuts from the partial convex hull
(1984)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
The efficient solution of capacitated plant location problems usually requires the development of specific software mainly when the problems are pure integer ones, standard mathematical programming codes being highly ...

Accés restringit per política de l'editorial
This paper presents a new method for assessing the bit error probability in a QAM system taking into account thermal noise, multipath distortion and phase Jitter. System signature is calculated for a system without any ...
Radiation damage evaluation on AlGaAs/GaAs solar cells
(1988-01)
Article.
Accés obert
Article.
Accés obert
A computer model to evaluate radiation damage on AlGaAs-based solar cells is reported. The model is based on a piecewise approach that divides the cell structure in an adaptive number of slices. Inside a particular slice ...
Sparse sets, lowness, and highness
(1986-08)
Article.
Accés obert
Article.
Accés obert
We develop the notions of “generalized lowness” for sets in PH (the union of the polynomial-time hierarchy) and of “generalized highness” for arbitrary sets. Also, we develop the notions of “extended lowness” and “extended ...

Text en actes de congrés.
Accés obert
A canonical model is examinated for generating coherent Weibull vectors wi th a desired correlation matrix and specified parameters. Such vectors may represent samples of a correlated radar signal. Statistical and espectral ...
