In this study, a real-time and dynamic time transfer method based on double-differenced (DD) kinematic (RTK) mode is proposed. First, the forms DD observations of Global Navigation Satellite System (GNSS) to fix ambiguity, then, all fixed single-differenced (SD) ambiguities are recovered while defining SD ambiguity datum; finally, uses realise by using ambiguities. Five different baseline links...

polybrominated diphenyl ethers as flame retardants prevent the branching mechanism of free radicals in gas phase during the combustion. therefore, they are used in electric and electronical instruments. these supplies are entering the landfills after use. the existing flame retardants in these landfills enter the air, water and soil and pollute them. in this paper a mass-transfer model is devel...

Background Transfer of micro-Injected oocytes into fallopian tubes is an alternative procedure for IVF-ET with a similar success rate. This could be either done immediately after ovum pick-up microinjected oocytes intrafallopian transfer (MIFT) or after a time interval zygote intrafallopian transfer (ZIFT). This study was designed to compare the outcomes of the two procedures. MaterialsAndMetho...

We define a new type cryptographical model called secure multi-party proof that allows any t players and a verifier to securely compute a function ) ,..., ( 1 t x x f : each of the players learns nothing about other players’ input and about the value of f , and the verifier obtains the value of f and it’s validity but learns nothing about the input of any of the players. It is implemented by a ...

OBJECTIVES Aging-related changes in motivation and the availability of resources have been hypothesized to result in social network changes in later life. However, few studies have examined associations of both motivation and resources with different aspects of social network composition in the same analytical context. The present study examined associations of key motivational (future time per...

The annual response variable in an ecological monitoring study often relates linearly to the weighted cumulative effect of some daily covariate, after adjusting for other annual covariates. Here we consider the problem of non-parametrically estimating the weights involved in computing the aforementioned cumulative effect, with a panel of short and contemporaneously correlated time series whose ...
