The theory of grey systems plays an important role in science, engineering and in the everyday life in general for handling approximate data. In the present paper grey numbers are used as a tool for assessing with linguistic expressions the mean performance of a group of objects participating in a certain activity. Two applications to student and football player assessment are also presented il...

Using a smoothing function and recent knowledge on the zeros of Riemann zeta-function, we compute pairs $(\Delta,x_0)$ such that for all $x \geq x_0$ there exists at least one prime in interval $(x(1 - \Delta^{-1}), x]$.

The microtubule-associated protein tau gene (MAPT) codes for a protein that plays an integral role in stabilisation of microtubules and axonal transport in neurons. As well as its role in susceptibility to neurodegeneration, previous studies have found an association between the MAPT haplotype and intracranial volume and regional grey matter volumes in healthy adults. The glycogen synthase kina...

Wire electric discharge machining (WEDM) is one of the advanced machining processes. Response surface methodology coupled with Grey relation analysis method has been proposed and used to optimise the machining parameters of WEDM. A face centred cubic design is used for conducting experiments on high speed steel (HSS) M2 grade workpiece material. The regression model of significant factors such ...

An e2cient and 3exible parameter estimation scheme for grey-box models in the sense of discretely, partially observed Itô stochastic di6erential equations with measurement noise is presented along with a corresponding software implementation. The estimation scheme is based on the extended Kalman 9lter and features maximum likelihood as well as maximum a posteriori estimation on multiple indepen...

this prioritization of the projects in the organization is a multi-criteria decision making (mcdm) that because of the uncertainties existing in experts judgments, these cannot be represented accurately with numbers. the scope of this research is the introduction of the grey system theory (grey possibility degree method) and application in ranking strategic organizational projects in an uncerta...
