"OpenStreetMap kreira i pruža slobodne geografske podatke, kao sto su karte gradova i naselja svakome tko ih želi. Projekt je nastao iz razloga sto vecina karata za koje mislite da su slobodne za koristenje, ustvari imaju pravna ili tehnicka ogranicenja za njihovu uporabu, sto sprijecava ljude da ih koriste na kreativne, produktivne te neocekivane nacine."

This paper presents hardware implementations of Taylor series. The focus will be on the exponential function but the methodology is applicable on any unary function. Two different architectures are investigated, one, original, straight forward and one modified structure. The outcomes are higher performance, lower area, and lower power consumption for the modified architecture compared to the original.

Hardware implementation of the exponential function using Taylor series

It is well known that nanomaterials properties and applications are dependent on the size, shape, and morphology of these structures. Among nanomaterials, silver nanoparticles (AgNPs) have attracted attention since they have considerably versatile properties, such as a variable surface area to volume ratio, which is very useful for many biomedical and technological applications. Within this scenario, small nanoparticle aggregates can have their properties reduced due to the increased size and alterations in their shape/morphology. In this work, silver nanoparticles aggregation was studied through chemical reduction of silver nitrate in the presence of sodium borohydride (reducing agent) and sodium citrate (capping agent). By changing the amount of reducing agent along the reaction, unaggregated and partially aggregated samples were obtained and characterized by UV–vis, zeta potential, and SAXS techniques. pH was measured in every step of the reaction in order to correlate these results with those obtained...

Under general conditions, the equation g(x, y) = 0 implicitly defines y locally as a function of x. In this article, we express divided differences of y in terms of bivariate divided differences of g, generalizing a recent result on divided differences of inverse functions.
