Current IT developments like component-based development and Web services have
emerged as effective ways of building complex enterprise-scale information systems and …

In this paper an algorithm for directional earth-fault relay without voltage inputs is presented.
This relay is intended for use in isolated neutral networks. For a reference quantity the …

This paper describes a new algorithm for longitudinal differential protection of transmission
lines. Classic stabilization is an unreliable method for avoiding unnecessary relay tripping in …

We report on hydrothermal synthesis, plate-like morphology, microstructure and magnetic
properties of hematite (α-Fe 2 O 3 ) plate-like particles. The sample is obtained immediately …

A series of cobalt-exchanged hydroxyapatite (CoHAp) powders with different Ca/Co ratios
and nominal unit-cell contents Ca10−xCox(PO4)6(OH)2, x = 0, 0.5, 1.0, 1.5 and 2.0, were …

Indications exist that paramagnetic calcium phosphates may be able to promote regeneration
of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the …

Pure and cobalt-exchanged hydroxyapatite (HAp and CoHAp) powders were synthesized
by hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, particle size analysis, …

Taking advantage of the flexibility of the apatite structure, nano- and micro-particles of
hydroxyapatite (HAp) were doped with different combinations of rare earth ions (RE 3+ = Gd, Eu, …

Transverse differential protection of double lines in double-fed networks has been discussed
by many papers. This paper investigates algorithms based on current increments for …

In this study, dense, fine-grained biphasic calcium phosphate bioceramics were designed
via the two-step sintering method. The starting powder was nanosized calcium-deficient …
