Enhancing user privacy by data driven selection mechanisms for finding transmission-relevant data samples in energy recommender systems

In order to find energy saving potentials, future home energy recommender systems needs a large database of historic energy consumption information from various appliances. Having reference data, those systems could decide whether an appliance is wasting energy or not. However,…

A Green Perspective on Structured Parallel Programming

Structured parallel programming, and in particular programming models using the algorithmic skeleton or parallel design pattern concepts, are increasingly considered to be the only viable means of supporting effective development of scalable and efficient parallel programs. Structured parallel programming models…

Chalcogenide fibers for infrared photonics: Recent developments

Compared to oxide based glasses, vitreous materials composed of chalcogen elements (S, Se, Te) show large transparency windows in the infrared. Indeed, chalcogenide glasses can be transparent from the visible up to 12 – 15 µm, depending on their compositions.…

Performance comparison of DA-TDE and CMA for MIMO equalization in multimode multiplexing systems

In this paper, we compare performances of the constant modulus algorithm (CMA) and data-aided time domain equalization (DA-TDE) algorithm for mode demultiplexing in few mode transmission systems. Simulation results of 4×56 Gbit/s QPSK mode-division multiplexed system show that the maximum…

Improving intergroup synchronization in a ring topology structure of semiconductor lasers by asymmetric coupling

We numerically demonstrate the enhancement of intergroup synchronization in a ring topology structure consisting of four semiconductor lasers (SLs) by asymmetric coupling. The lasers are divided into two groups, each of which consists of two non-adjacent lasers with the same…

A novel fiber with ultra-low-loss and large-effective-area for the next generation communication

Fiber loss and nonlinear effect are the main important factors for high-speed coherent communication. A novel communication fiber with ultra-low loss (0.165dB/km) & large effective area (about 110µm2) at 1550nm wavelength is proposed. Compared to the conventional single-mode fiber, it…

Advanced fiber Bragg gratings for microwave photonics applications

Owing to the unique features of flexible spectral characteristics, low loss, light weight, compact footprint, and compatibility with other fiber-optic elements, fiber Bragg gratings (FBGs) have been extensively used in various microwave photonics systems. In this work, the recent development…

A new method of generating public key matrix and using it for image encryption

It is very difficult to find the inverse of a matrix in Galois field using standard matrix inversion algorithms. Hence, any block-based encryption process involving matrix as a key will take considerable amount of time for decryption. The inverse of…

Single photon emitters in dilute nitrides: Towards a determinist approach of quantum dot-photonic crystal nanocavity coupling

In dilute nitrides [e.g., Ga(AsN), (InGa)(AsN)] the formation of stable N-2H-H complexes following H irradiation removes the effects nitrogen has on the optical (i.e., refractive index [1]), structural [2], and electronic [3] properties of the material. In particular, H binding…
