Generation of circularly polarized (CP) light with high purity and intensity was achieved using a single-, parallel, multi-layered luminescence-based CP convertor composed linearly luminescence (LPL) film quarter-wave plate.

The integration of Renewable Energy Sources (RESs) into distribution networks has increased in recent years due to numerous advantages. However, the RESs are intermittent and uncertain therefore may cause various limitations such as high lines loading large voltage deviations, especially during generation low demand periods. Thus, this leads an upper limit for integrated capacity network, entit...

The spectrally-sliced coherent receiver is an attractive solution for future optical access network applications where cost a sensitive factor, as it enables reduced bandwidth of the analog front-end components and analog-to-digital convertors when compared to conventional intradyne receiver. In proof-of-concept experiment, we demonstrate single-polarization 50 Gb/s QPSK C-band transmission exp...

the object of this paper is to establish a summability factor theorem for summabilitya, , k  1 k  where a is the lower triangular matrix with non-negative entries satisfying certain conditions.

we obtain sufficient conditions for the series σanλn to be absolutely summable of order k by atriangular matrix.

it is proved that by using bounds of eigenvalues of an interval matrix, someconditions for checking positive deniteness and stability of interval matricescan be presented. these conditions have been proved previously with variousmethods and now we provide some new proofs for them with a unity method.furthermore we introduce a new necessary and sucient condition for checkingstability of interv...

Vulnerability is a weakness, shortcoming or flaw in the system or network infrastructure which can be used by an attacker to harm the system, disrupt its normal operation and use it for his financial, competitive or other motives or just for cyber escapades. In this paper, we re-examined the various types of attacks on industrial control systems as well as on social networking users. We have li...

When high-energy photons are absorbed in a semiconductor or metal, electrons and holes are generated with excess kinetic energy, so-called hot carriers. This extra energy is dissipated, for example, by phonon emission, which results in sample heating. Recovery of hot carriers is important for detectors, sensors, and power convertors; however, the design and implementation of these devices is di...

A Software Defined Radio is a radio receiver that is reconfigurable by software. This reconfigurability leads to flexibility that can be used to offer more functionality to the user. Also, because common reconfigurable hardware can be used for very diverse radio interfaces, production and logistics can be faster and cheaper. In our Software Defined Radio project we aim at a receiver that is abl...
