In this work we introduce a green inventory routing problem termed the Stochastic Inventory Routing Problem on Electric Roads (S-IRP-ER), in which hybrid vehicle navigates road network with charging opportunities some sections, to cover non-stationary stochastic demand of single product for set retailers network. We model using isochrone graphs represent real an graph nodes are located such tha...

We present a unified approach to (bi-)orthogonal basis sets for gravitating systems. Central our discussion is the notion of mutual gravitational energy, which gives rise ‘self-energy inner product’ on mass densities. consider first-order differential operator that self-adjoint with respect this product, and prove general theorem conditions under set arises by repeated application operator. the...

Luminosity and mass functions in the old open cluster NGC 188 are analysed by means of J and H 2MASS photometry, which provides uniformity and spatial coverage for a proper background subtraction. With an age of about 6–8 Gyr, NGC 188 is expected to be suffering the effects of advanced dynamical evolution. Indeed, previous works in optical bands have suggested the presence of mass segregation. ...

Abstract Some significant indication identifying a coastal dynamic during Late Pleistocene to Recent is the evolution of isochrone patterns throughout glacial-interglacial stages. This study aims identify sediments stratification Jakarta Bay – in framework triggered by sea-level changes last prominent climatic The several high-resolution seismic records lines were interpreted illustrate differe...

We report the discovery of four new open clusters (named as QC 1, 2, QC3 and 4) in direction Cygnus Cloud select their members based on five astrometric parameters (l, b, \varpi, \mu^*_{\alpha}, \mu_{\delta}) Gaia DR2. also derive astrophysical for each cluster. Structure are generated by fitting radial density distribution with King's profile. Using solar metallicity, we performed isochrone-fi...

Abstract Coma Berenices (Coma Ber), an open cluster about the same age as Praesepe and Hyades (700–800 Myr) is, despite being only 85 pc away, less well studied than its famous cousins. This is due principally to sparseness low proper motion, which together made Ber’s membership challenging establish pre-Gaia. We have curated a new list of members based on Gaia DR2 astrometry, derived metallici...

Population migration, accompanied by urbanization, has led to an increase in the urban-settled population. However, quantitative studies on distribution of population, especially at fine scale, are limited. This study explored relationship between characteristics human perceived environment and settled proposed a method predict trend Through semantic segmentation street view images accessibilit...

Open clusters (OCs) are regarded as tracers to understand stellar evolution theory and validate models. In this study, we presented a robust approach identifying OCs. A hybrid method of pyUPMASK RF is first used remove field stars determine more reliable members. An identification model based on the algorithm built 3714 OC samples from Gaia DR2 EDR3 then applied identify candidates. The candida...
