The purpose of this paper is describes the use of grey pridiction in linear programming problems. Some definitions and concepts of grey system theory are introduced and then, we introduced GM(1,1) and fractional order accumulation into grey model. Due to the fluctuation of prices and the lack of certainty data in the market, optimal production was calculated to optimize the profit from sales us...

This paper presents the performance quantification of different green-grey infrastructures, including rainfall-runoff and infiltration processes, on overland flow its connection with a sewer system. The present study suggests three main components to form structure proposed model-based assessment. first two provide optimal number green infrastructure (GI) practices allocated in an urban catchme...

This study deals with the selection of cutting process using grey fuzzy relation approach. The analysis was performed plasma arc machining, laser beam and abrasive waterjet machining on three different workpiece thicknesses speeds. objective to select best considering several performance characteristics such as time, dimensional accuracy, kerf width, surface roughness. Data normalization, coeff...

This paper investigates the intonation development of an infant during the first year. Three stages include the goo stage (2-3 months), the canonical babbling stage (7-9 months), and the variegated babbling stage (10-12 months). Falling contour was found to be the most common intonation at the goo stage. Rising contour was found to be the dominant intonation both at the canonical babbling and t...

The aim of this investigation is to optimize the process parameters obtain minimum corrosion rate and weight loss Al/SiCp metal matrix composites. A Taguchi based grey relation analysis was carried out. such as number hours dipped in 3% NaCl solution, vol.% SiCp aging at 170°C for were considered. working range each fixed on low rate. test out using relationship analysis. Three factor three lev...

this paper applies a new multi attribute decision-making (madm) model to help companies for enterprise resource planning (erp) selection problem based on balanced score card method. this paper uses three-parameter interval grey numbers which is derived from grey theory (was proposed by j. deng). this numbers is used instead of linguistic variables. beside, a new weighting method that outcomes f...

Individuals with developmental prosopagnosia exhibit severe and lasting difficulties in recognizing faces despite the absence of apparent brain abnormalities. We used voxel-based morphometry to investigate whether developmental prosopagnosics show subtle neuroanatomical differences from controls. An analysis based on segmentation of T1-weighted images from 17 developmental prosopagnosics and 18...

The kinetic components of the β-amyloid ligand (18)F-flutemetamol binding in grey and white matter were investigated through spectral analysis, and a method developed for creation of parametric images separating grey and white matter uptake. Tracer uptake in grey and white matter and cerebellar cortex was analyzed through spectral analysis in six subjects, with (n=4) or without (n=2) apparent β...
