Near-infrared transmission spectrum of the warm-uranus GJ 3470b with the Wide Field Camera-3 on the Hubble Space Telescope

, 2014
The atmospheric composition of low-mass exoplanets is the object of intense observational and theoretical investigations. GJ3470b is a warm uranus recently detected in transit across a bright late-type star.

Study on Gear Fault Diagnosis Technology based on the Method of Transmission Error

Jixie chuandong, 2015
In view of the problem of the difficulty in precise diagnosis of tooth surface fault of gear transmission system under the complicated working conduction,a fault diagnosis method based on transmission error in gear transmission system is proposed ...

The design and analysis of single flank transmission error testor for loaded gears [PDF]

Due to geometrical imperfections in gears and finite tooth stiffnesses, the motion transmitted from an input gear shaft to an output gear shaft will not have conjugate action.

Multi-Parameter Optimization of Angle Transmission Ratio of Steer-by-Wire Vehicle

World Electric Vehicle Journal
Aiming at the problem of the insufficient stability of the unified model of steering angle transmission ratio at high speeds, we introduce a novel control strategy that integrates the yaw rate gain, lateral acceleration gain, vehicle speed and steering ...

X chromosome transmission ratio distortion in Cftr +/- intercross-derived mice

BMC Genetics, 2007
Background Cystic fibrosis (CF) mice, created with a genetically engineered mutation in the Cystic fibrosis transmembrane conductance regulator (Cftr) gene, may develop intestinal plugs which limit their survival past weaning.

Variable Ratio Hydrostatic Transmission Simulator for Optimal Wind Power Drivetrains

International Journal of Rotating Machinery, 2017
This work presents a hydromechanical transmission coupled to an electric AC motor and DC generator to simulate a wind power turbine drive train. The goal of this project was to demonstrate and simulate the ability of a hydrostatic variable ratio system ...

Reduced Gene Transmission and Genotypic Ratio

Caryologia, 1968
SUMMARYIt is a common phenomenon that many of the radiation-induced mutations in higher plants show a deficiency of mutants in a segregating population, although the mutant genes are of a simple recessive nature. The number of heterozygotes is also less than the expected ratio of 1 normal: 2 heterozygotes. Moreover, mutant lines segregating a similarly

Arrhenotoky and oedipal mating in the northern fowl mite (Ornithonyssus sylviarum) (Acari: Gamasida: Macronyssidae)

Parasites & Vectors, 2012
Background The northern fowl mite (NFM; Ornithonyssus sylviarum) is a blood-feeding ectoparasite of birds and a major pest of poultry in the United States. Mite populations spread rapidly in commercial flocks, reach peak burdens of >70,000 mites per bird
