In this paper, the characteristics and a model of a side illuminated twin waveguide, pin-photodiode based on scattering parameters, is proposed. The equivalent small-signal model involves both the photodetector and the coplanar waveguide transmission line models. The measurement of the optoelectronic conversion parameter (S21) of photodetector at 1.55 μm is done by an optical heterodyne techniq...

For economic benefit of wind power generation, the equivalent conversion relationships and models between the different “quality” energy are studied deeply in the conversion processes of wind energy. Considering the effect of load demand characteristics and energy supply price on the wind energy utilization mode comprehensively, the multi-objective trans-utilization optimization model of wind e...

in this paper, a non-dominated sorting genetic algorithm-ii (nsga-ii) based approach is presented for distribution system reconfiguration. in contrast to the conventional ga based methods, the proposed approach does not require weighting factors for conversion of multi-objective function into an equivalent single objective function. in order to illustrate the performance of the proposed method,...

Recent studies identified the presence of a male polycystic ovarian syndrome (PCOS), which mainly affects men whose female relatives are afflicted with PCOS, caused by genes responsible for the susceptibility of this syndrome in women. Similar hormonal, metabolic, and clinical alterations occurring in PCOS women have also been reported in their male relatives, suggesting a association between t...

In this paper, we first study the conversion of weighted two-way automata to one-way automata. We show that this conversion preserves the unambiguity but does not preserve the determinism. Yet, we prove that the conversion of an unambiguous weighted one-way automaton into a two-way automaton leads to a deterministic two-way automaton. As a consequence, we prove that unambiguous weighted two-way...

Schema conversion problem aims to convert a source schema S in the given model M1 to an equivalent target schema T in the desired model M2. In this paper, we especially study schema conversion problem between XML and relational models. We present three semantics-based schema conversion algorithms: 1) CPI converts an XML schema to a relational schema while preserving semantic constraints of the ...

This paper proposes the design of Star Schema of a Data Warehouse and conversion to its equivalent Graph based Multi Dimensional Data Model (GMDDM Model). Design of Star Schema facilitates in constructing Graph based Multi Dimensional Data Model. The GMDDM model defines a set of graph based constructs that are used to specify the conceptual level design of Data Warehouse. Data warehouse represe...
