A note on the analysis error associated with 3D-FGAT
نویسنده
چکیده
The analysis error variance of a 3D-FGAT assimilation is examined analytically using a simple scalar equation. It is shown that the analysis error variance may be greater than the error variances of the inputs. The results are illustrated numerically with a scalar example and a shallow-water model.

A Comparative Study of VHDL Implementation of FT-2D-cGA and FT-3D-cGA on Different Benchmarks (RESEARCH NOTE)
This paper presents the VHDL implementation of fault tolerant cellular genetic algorithm. The goal of paper is to harden the hardware implementation of the cGA against single error upset (SEU), when affecting the fitness registers in the target hardware. The proposed approach, consists of two phases; Error monitoring and error recovery. Using innovative connectivity between processing elements ...
متن کاملGypsum Dissolution Effects on the Performance of a Large Dam (TECHNICAL NOTE)
Upper Gotvand dam is constructed on the Karun River located in the south west of Iran. In this paper, 2D and 3D models of the dam together with the foundation and abutments were constructed and several seepage analyses were carried out. Then the gypsum veins scattered throughout the foundation ground and also the seepage pattern were included in the models, hence the dissolution law of gypsum, ...

متن کاملA note on “Supplier selection by the pair of nondiscretionary factors-imprecise data envelopment analysis models”
Recently, Farzipoor Saen [Journal of the Operational Research Society, 60(11), 1575–1582 (2009)] proposed a method based on data envelopment analysis to identify optimistic efficient suppliers in the presence of nondiscretionary factors-imprecise data. This short communication aims at showing a computational error in computing the value of preference intensity parameter in Farzipoor Saen’s [...
متن کاملEvaluating the Effects of Ceramic Layer and Thermal Dam on Optimizing the Temperature Gradient of a Gasoline Engine Piston (TECHNICAL NOTE)
The purpose of this paper is to evaluate the effect of different methods for improving the temperature gradient of a specified gasoline engine piston. With a robust FE based software, 3D thermal analyses have been carried out for the piston model. Unlike previous studies, the effects of both fully and locally ceramic layers on the crown top surface were considered. It was found that a fully cer...
