Studies on the Rationalization of Thinning Operation
1. For comparing the time requirements of the plants singling works in the traditional method and the platform method, the survey on the work diaries and the time studies on singling works were carried out in turnip fields.2. From the results of the survey on the work diaries, it was comfirmed that the most labour saving work sequence was “drilling in ...

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

On Some Stationary INAR(1) Processes with Compound Poisson Distributions
Aly and Bouzar ([2]) used the backward approach in presence of the binomial thinning operator to construct underdispersed stationary first-order autoregressive integer valued (INAR (1)) processes.

Coherent Forecasting for a Mixed Integer-Valued Time Series Model
In commerce, economics, engineering and the sciences, quantitative methods based on statistical models for forecasting are very useful tools for prediction and decision.

The Saffman-Taylor problem for an extremely shear-thinning fluid [PDF]
We consider a steady flow driven by pushing a finger of gas into a highly shear-thinning power-law fluid, with exponent n, in a Hele-Shaw channel. We formulate the problem in terms of the streamfunction , which satisfies the p-Laplacian equation (with ),

Likelihood Inference for Generalized Integer Autoregressive Time Series Models
For modeling count time series data, one class of models is generalized integer autoregressive of order p based on thinning operators. It is shown how numerical maximum likelihood estimation is possible by inverting the probability generating function of

Residual Analysis with Bivariate INAR(1) Models
In this paper we analyze forecasting errors made by random coefficients bivariate integer-valued autoregressive models of order one. These models are based on the thinning operator to support discreteness of data.

A preliminary evaluation of FY-4A visible radiance data assimilation by the WRF (ARW v4.1.1)/DART (Manhattan release v9.8.0)-RTTOV (v12.3) system for a tropical storm case [PDF]
Satellite visible radiance data that contain rich cloud and precipitation information are increasingly assimilated to improve the forecasts of numerical weather prediction models.
