Meijer, Rohwedder, and Wansbeek (MRW, Journal of Business & Economic Statistics, 2012) developed methods for prediction a single earnings figure per worker from mixture factor models fitted using data multiple linked sources. MRW applied their method parameter estimates Kapteyn Ypma's model (KY, Labour Economics 2007) to Swedish workers aged 50+. First, we replicate MRW's empirical analysis the...
We report on thermal conductivity of W films 350 nm thick sputter-deposited by glancing angle deposition (GLAD). The 3? method is used to measure the in-plane kx and ky for deposited with a ? 0° 80°. For classical (?=0°), 71 m?1 K?1, whereas GLAD (?=80°) conduction drops kx=3.2 K?1 ky=4.8 K?1. anisotropy corresponds heat favored in direction perpendicular axis, which related anisotropic columna...
in this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. in addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. in the proposed control metho...
Z-Source converter or impedance-source converter is a kind of power converters, which has the responsibility to convert the direct current to alternative current. This converter with respect to its circuit diagram acts as a buck-boost converter except it doesn’t use from DC-DC converter bridge. Γ-source inverters are one of the conventional converters based on impedance-sources; which have been...
The rate limiting step in isoprenoid biosynthesis is catalyzed by 3-hydroxy-3-methylglutaryl CoA reductase (HMGR, EC 1.1.1.34). In plants, HMGR is encoded by small gene families whose members are differentially expressed. In tomato, hmg2 was previously isolated and sequenced. We report the isolation and sequence analysis of a clone (pCD4) encompassing exon I of tomato hmg1 which encodes the put...
In this paper, a new step-upresonant DC-DC converter without an auxiliary switch is introduced. All the switching elements act under zero current switching condition at turn-on and turn-off instants. The proposed converter has a simple auxiliary circuit including an inductor and a capacitor. In addition, the size of the main inductor is considerably reduced because it acts as a resonant inducto...
In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...
