The EU anti-migrant smuggling operation in the Mediterranean sea – known as ‘EUNAVFOR Med’ or ‘Operation Sophia’ – is now entering its operational phase, aimed at boarding and seizing on the high seas vessels suspected of being used for human smuggling and trafficking. This follows a first phase of intelligence gathering on smuggling networks and is intended to precede operations due to take pl...

We report temperature phase-matched second-harmonic generation of 1.064-Am radiation in Ti-indiffused waveguides in MgO-doped LiNbO3 substrates. Noncritical phase matching of the TE2 mode was achieved at 102-106°C. Owing to the high-temperature operation and the low photorefractivity of the waveguide, it was possible to generate 22-mW average-power 532-nm output. No evidence of photorefractive ...

BACKGROUND New opportunities are emerging for nurses as sovereign health care specialists. In accordance with British and American experience, several universities on the European Continent started Advance Nursing Practice programs for nurses to become certified nurse specialists, functioning as intermediates between the consultant, the ward nurse and the patient. AIMS This observational stud...

In this article are presented the basic principles of the numerical protections used for protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a numerical distance protection DIPA 100, for a high-voltage line (an example from practice). For the numerical relay, is shown the protection characteristic of DIPA 100, characteristics of operation to faults ‘phase-p...

This paper proposes a new scope calculation system named a phase-based approach. The new system treats scope calculation as a feature-matching operation between more than one interpretable feature related to quantification (henceforth Fqunt1 ). We call this matching operation Fq.nrmatching. It is shown that the working space of Fquanrmatching is restricted by a syntactic unit phases. Given the ...

This paper describes a new, generalized and efficient steadystate model for the performance analysis of isolated six-phase induction generators. The mathematical model is formed directly from the equivalent circuit of six-phase induction generator by nodal admittance method. The proposed model is very simple which completely avoids lengthy derivations of non linear equations. The model results ...

Recently, hybrid modular multi-level converters, which are configured as full and half bridge sub-modules, are developed and utilized in the wide area of applications. Compared to its non-hybrid counterpart, these converters have several advantages such as the ability to nullify the DC side fault current and controlling AC side reactive power during the faults. This paper proposes a modified ph...

the bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. furthermore, simulation and optimization based on this reactor model are carried out. the results of simulat...

This paper presents a three-phase 12-pulse phasecontrolled rectifier with unity displacement factor, low line current harmonic content, two quadrant operation and absence of phase shifting transformer. The circuit is composed by two three-phase 6-pulse rectifiers parallel connected by four balancing reactors. One is a conventional thyristor rectifier with a lag firing angle (a). The other is an...

in this paper, computer simulation of a three-phase synchronous motor drive is described. this drive/system is supplied with a new type of pulse-width modulated voltage source inverter (pwm vsi) whose amplitude of the first harmonic, compared to a conventional sinusoidal pwm vsi, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...
