Abstract—Reference spur is a limiting performance factor in an integer-N phase-locked loop (PLL). In this paper, we investigate the effect of VCO gain, ripple magnitude in VCO tuning voltage and reference frequency with reference spur magnitude. Normally, VCO gain and reference frequency are chosen

Abstract. Spur-thighed tortoise is a vulnerable species. The local declines of populations led to an imperative need for conservation. Testudo graeca reaches its northern range limit in Dobrogea region, Romania. We studied a population from this region, which occupies an enclosed area of 32 ha

Abstract: In a mass transit railway environment with spur lines, the interleaving of trains along different branches and the layover time at different termini could have a significant impact on fleet size and hence cost. These operational parameters could be systematically optimized without

Abstract:Gears made from composite materials are widely used in many power and motion transmission applications. Due to lower weight to stiffness ratio, composite gears may be replaced by conventional material gears in power transmission systems. Design of gears with asymmetric teeth enables

ABSTRACT: Interdependence is ubiquitous, and often central, across comparative politics. In comparative political economy, for example, globalization and rising capital mobility imply tax competition that suggests the fiscal policies of one country must depend crucially upon those of other

Condition monitoring of gears with vibration analysis and Spectrometric Oil Analysis Programs (SOAP) are widely accepted and used in the military aviation industry. Whilst the literature to date has shown the application of the Acoustic Emission (AE) technique to gearbox health monitoring still be in its infancy, there exist opportunities to develop the technique into a complementary diagnostic tool. In developing such a tool, it is imperative that an understanding of the source of AE activity is established. This paper presents experimental results that explore the AE source during a gear mesh and has led to quite unique and significant observations.

The exponential growth in the amount of genomic data has spurred growing interest in large scale analysis of genetic information. Bioinformatics applications, which explore computational methods to allow researchers to sift through the massive biological data and extract useful information

Abstract—This paper presents a mechanism that explains exactly the cause of spurs at the output of offset-PLL (OPLL) transmitters. By a rigorous analysis of the relationship between the signals and disturbances in OPLL, accurate formulas are ob-tained which elucidate systematically
