In this note we explore the possibility of measuring the action of the intrinsic gravitomagnetic field of the rotating Earth on the orbital motion of the Moon with the Lunar Laser Ranging (LLR) technique. Indeed, expected improvements in it should push the precision in measuring the Earth-Moon range to the mm level; the present-day Root-Mean-Square (RMS) accuracy in reconstructing the radial co...

The paper argues that Reconfigurable Manufacturing Systems (RMS) and Environmentally Benign Manufacturing (EBM) could play a very important role in the context of Green Revolution. The paper analyzes RMS as a machining system which can be created by incorporating basic process modules both hardware and software that can be interchangeable, rearranged or replaced quickly and reliably. The author...

The power supply analysis and design results of Sherman and Hamacher are extended to include approximate solutions to the nonlinear equations that define the rectifier turn-on angles. Additionally, peak rectifier current solely as a function of ripple factor, as well as the inverse relationship, i.e., ripple factor as a function of peak rectifier current, are also provided. Simplified exact equ...

Rhabdomyosarcomas (RMSs) are the most common soft tissue sarcomas of childhood and adolescence. To date, there are no effective treatments that target the genetic abnormalities in RMS, and current treatment options for high-risk groups are not adequate. Over the past two decades, research into the molecular mechanisms of RMS has identified key genes and signaling pathways involved in disease pa...

This article investigates how a …rm’s …nancial strength a¤ects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German …rms in high-tech manufacturing industries. The model incorporates a measure of the …rm’s …nancial strength, derived from its credit rating, which is shown to lead to substantial di¤erences in estimates of the costs and expected lo...

Information asymmetry creates value and incentives for ̄rms from di®erent countries to merge. To demonstrate this point, we develop a model of international trade under oligopolistic competition and asymmetric information, in which domestic ̄rms are informed of the local market demands, but foreign ̄rms are not. By emphasizing two features of a merger between a domestic ̄rm and a foreign ̄rm, w...

In this paper, average frequency correlation and rootmean-squared (rms) delay spread estimation for wireless communication systems are described. A practical algorithm for averaged channel frequency correlation estimation, which can be used for measuring frequency selectivity, is given. Average rms delay spread of the channel is obtained directly from the channel frequency correlation estimate ...

It is well known that series arc faults in Low Voltage DC (LVDC) distribution system occur at unintended points of discontinuity within an electrical circuit. These faults can make circuit breakers not respond timely due to low fault current. It, therefore, is needed to detect the series fault for protecting circuits from electrical fires. This paper proposes a novel scheme to detect the series...
