In this paper, the researchers have proposed a multi-dimensional knapsack model for project capital budgeting problem in uncertain situation which has been modeled through fuzzy sets. The optimistic and pessimistic situations were considered and associated deterministic models were yielded. Numerical example has been supplied toillustrate the performance of proposed model. The results were prom...

This work aims to study the dislocation or nodal lines of 3D Berry's random wave model. Their expected length is computed both in isotropic and anisotropic cases, being them compared. Afterwards, case asymptotic variance distribution are obtained as domain grows whole space. Under some integrability condition on covariance function, a central limit theorem established. The includes monochromati...
