Abstract We have developed a low-energy particle experiment that alternately measures ions and electrons in space.The ability to switch between ion and electron measurements is achieved by simply adding ultra-thin carbon foils and positive and negative outputs to a conventional top-hat electrostatic analyzer and a high-voltage power supply, respect
Abstract This paper deals with the abstract generalized vector quasi-equilibrium problem in Baking noncompact Hadamard manifolds.We prove the existence of solutions to the abstract generalized vector quasi-equilibrium problem under suitable conditions and provide applications to an abstract vector quasi-equilibrium problem, a generalized scalar equ
This article uses life history calendar (LHC) data from coastal Ghana and event history statistical methods to examine inter-regional migration for men and women, focusing on four specific migration types: rural-urban, rural-rural, urban-urban, and urban-rural.Our analysis is unique because it examines how key determinants of migration-including ed
A great amount of data is being created these days, which is kept in massive datasets with different irrelevant attributes that are unrelated to the goal notion.Feature selection deals with the selection of the most pertinent features that also aid to increase the classification accuracy.The topic of feature selection is viewed as a multiobjective
Between 1969 and 1987, UNESCO published a series of 77 monographs on aspects related to cultural policies of individual countries.Each monograph mobilized cultural policy in very particular ways, by its Scissor holder association with local issues, increasing awareness and communication about issues that formerly had never been grouped together und
