Are Software Products Accurate in GPS Observation

There is a growing dependence on GPS technology in recent years, and digital applications such as Google map, and fitness apps DO bring some convenience to our daily life. However, have you ever considered whether or not the GPS observation conducted by different software products is accurate? This article tries to look into this issue, and finds out that commercial software products can only present acceptable accuracy in small polygons of network considering their capacity and few numbers of parameters for processing of GPS data. However, if the network is more extended, there is no other choice but using scientific software products.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton

Remarks on the Complexity of Signed k-Domination on Graphs

ABSTRACT This paper is motivated by the concept of the signed k-domination problem and dedicated to the complexity of the problem on graphs. For any fixed nonnegative integer k, we show that the signed k-domination problem is NP-complete for doubly chordal graphs. For strongly chordal graphs and distance-hereditary graphs, we show that the signed k-domination problem can be solved in polynomial time. We also show that the problem is linear-time solvable for trees, interval graphs, and chordal comparability graphs

ABSTRACT Waterleaf ( Talinum triangulare (Jacq.) Willd has long been eaten in Indonesia as vegetable and the main parts consumed are leaves and young shoots. Waterleaf is sticky presumably due to its pectin content which is associated to dietary fiber. The dietary fiber which
