In the context of tomographic cosmic shear surveys, there exists a nulling transformation weak lensing observations (also called BNT transform) that allows us to simplify correlation structure observations, as well build observables depend only on localized range redshifts and thus independent from low-redshift/small-scale modes. This procedure renders possible accurate, from-first-principles, ...

we consider an m/g/1 queue with regular and optional phase vacation and withstate dependent arrival rate. the vacation policy is after completion of service if there are no customers in the system, the server takes vacation consisting of k -phases, each phase is generally distributed. here the first phase is compulsory where as the other phases are optional. for this model the supplementary var...
