Estimating the benefits of dedicated unloading bays by field experimentation

open access: yesSocial Science Research Network, 2020
In most dense urban environments in emerging markets, retail deliveries are very fragmented to thousands of nanostores. It is not uncommon for a delivery route to include more than 60 stops. Unloading bays are often blocked by regular traffic. Due to the

A Note on Divisible Points of Curves [PDF]

open access: yes, 2014
Let $C$ be an irreducible algebraic curve defined over a number field and inside an algebraic torus of dimension at least 3. We partially answer a question posed by Levin on points on $C$ for which a non-trivial power lies again on $C$.

Weather Induced Quasi-Periodic Motions in Estuaries and Bays: Meteorological Tide

open access: yes, 2020
Influenced by weather, the estuaries and bays often exhibit recurring oscillations in flow and water level similar to astronomical tides. The weather impact however is less regular than tides and more difficult to predict. The spectrum of weather induced

Nearshore surface temperatures in Antofagasta Bay (Chile) and adjacent upwelling centers

open access: yesCiencias Marinas, 2007
 Several years of sea surface temperature data (1997–2003) for the coast of Antofagasta Bay—a semi-enclosed bay in northern Chile—were analyzed in order to further exploring the nature of a warm-water retention pattern inside the bay.
