We report the detection of a 110 MG cyclotron harmonic in the SDSS-spectrum of the magnetic cataclysmic variable (MCV) RX J1554.2+2721. This feature was noted earlier by others but remained unexplained. The wide spectral coverage of the new spectrum together with the earlier detection of a Zeeman split Lyα line in a field of 144 MG makes the identification almost unambiguous. We propose to expl...

Function Block Adapters (FBAs) are new modeling elements, responsible for the connection of UML capsules and function blocks of the IEC 61131-3 standard. FBAs contain an interface to capsules as well as to function blocks and a description of the mapping between these interfaces. In this paper we discuss implementation issues of FBAs. While the specification of FBAs is completely platform-indep...

Underwater acoustic sensor networks (UWA-SNs) are envisioned to perform monitoring tasks over the large portion of the world covered by oceans. Due to economics and the large area of the ocean, UWA-SNs are mainly sparsely deployed networks nowadays. The limited battery resources is a big challenge for the deployment of such long-term sensor networks. Unbalanced battery energy consumption will l...

We investigate the vacuum expectation value of the surface energy-momentum tensor for a massive scalar field with general curvature coupling parameter obeying the Robin boundary conditions on two codimension one parallel branes in a (D + 1)-dimensional background spacetime AdSD1+1 ×Σ with a warped internal space Σ. These vacuum densities correspond to a gravitational source of the cosmological ...

Social balance theory describes allowable and forbidden configurations of the topologies of signed directed social appraisal networks. In this paper, we propose two discrete-time dynamical systems that explain how an appraisal network evolves towards social balance from an initially unbalanced configuration. These two models are based on two different socio-psychological mechanisms respectively...

This paper proposes a multi-stage power generation system suitable for renewable energy sources, which is composed of a DC-DC power converter and a three-phase inverter. The DC-DC power converter is a boost converter to convert the output voltage of the DC source into two voltage sources. The DC-DC converter has two switches operates like a continuous conduction mode. The input current of DC-DC...

Mixed-model assembly lines are increasingly accepted in many industrial environments to meet the growing trend of greater product variability, diversification of customer demands, and shorter life cycles. In this research, a new mathematical model is presented considering balancing a mixed-model U-line and human-related issues, simultaneously. The objective function consists of two separate com...

ABSTRACT AAPSM masks require OPC correction through pitch in order to print a linear dark line response vs the design CDs. The masks also require correction for the clear intensity imbalance caused by the phased etched Qz wall edge. The clear intensity can be balanced by two approaches;(or a combination of the two) data biasing or wet undercut etching of the Qz etched opening. IC manufacturers ...

A single stage quadrature hybrid coupler with enhanced flat balance over a wide bandwidth is presented in this article. The present coupler is realized by replacing the transmission line sections of the conventional two-branch coupler by their equivalent parallel coupled microstrip lines (PCML). The impedance controlled wide-bandpass response produced by the PCML is utilized to achieve flat bal...

Three diets with varying amino acid levels were fed in two nitrogen balance studies and two fattening experiments in order to determine the nitrogen retention and growth performance of boars of different sire lines. A total of 12 boars, 6 crossbreed boars sired by Piétrain boars (Study 1) and 6 crossbreed boars sired by Duroc boars (Study 2) were used in the nitrogen balance studies. The feedin...
