A trick to improve PRD during compressed sensing ECG reconstruction

In the problem of compressed sensing (CS) successful reconstruction can be achieved by maintaining a low mutual coherence between the columns in the vector space. In this work, a way to increase the mutual incoherence is introduced. This is achieved…

Successive Overrelaxation for Laplacian Support Vector Machine

Semisupervised learning (SSL) problem, which makes use of both a large amount of cheap unlabeled data and a few unlabeled data for training, in the last few years, has attracted amounts of attention in machine learning and data mining. Exploiting…

Integrated microwave photonics phase shifter using on-chip stimulated Brillouin scattering

In this paper we consider two new topologies of a tunable microwave photonic phase shifter using stimulated Brillouin scattering. In the first topology, independent phase and amplitude control of an optical carrier was achieved by controlling two SBS pumps in…

Micro-size graphene strip as a surface plasmon resonance based bulk refractive index sensor

We have studied numerically the potential use of a micro-size graphene strip as a surface plasmon resonance based bulk refractive index sensor in the THz frequency regime. Our accurate computational instrument was in-house algorithm based on integral equations (IE) and…

VLC link with LEDs used as both transmitters and photo-detectors

The paper presents development of a 10 Mbit/s visible light communications link that uses lighting LEDs as both transmitters and receivers. The system uses the simple binary on-off keying modulation without any equalization. Transmission distances exceeding 20 cm were obtained…

Self-positioning of a team of flying smart cameras

Quadcopters are highly maneuverable and can provide an effective means for an agile dynamic positioning of sensors such as cameras. In this paper we propose a method for the self-positioning of a team of camera-equipped quadcopters (flying cameras) around a…

ML-TREE: A Tree-Structure-Based Approach to Multilabel Learning

Multilabel learning aims to predict labels of unseen instances by learning from training samples that are associated with a set of known labels. In this paper, we propose to use a hierarchical tree model for multilabel learning, and to develop…

Early-word-based montgomery modular multiplication algorithm

Modular multiplication is basic operation in public key cryptosystems like RSA. Montgomery modular multiplication being efficient is widely used. It is based on additions and shift operations. Each iteration requires a right shift, therefore in a word based architecture a…
