Improved face-to-face communication using noise reduction and speech intelligibility enhancement

Significant improvements in intelligibility of speech in noise can be obtained by modifying the speech signal in the time and/or frequency domains. However, most speech intelligibility enhancement algorithms are designed to use clean speech as an input, and their performance…

Supervisor Synthesis for Networked Discrete Event Systems With Communication Delays

We investigate supervisory control of networked discrete event systems with asynchronouscommunication between the plant and supervisor. The observation and control may be randomly delayed. The delays are bounded and will not change the order of observation (FIFO). Our goal is to…

Tunable laser based on composite microchip using ND:PLZT as both tuning and gain medium

A composite microchip laser composed of neodymium doped yttrium aluminum garnet (Nd:YAG) and neodymium doped lanthanum-modified lead zirconate titanate (Nd:PLZT) is proposed. The high electro-optic effect of PLZT, combined with the high gain effect of Nd3+, makes Nd:PLZT not only…

Optical fiber technologies for in-vivo light delivery and optogenetics

In optogenetics, light-sensitive proteins are genetically targeted into specific classes of neurons in living animal models (typically mice), making possible to control their neural activity by means of visible light delivered into the brain tissue. In this paper, recent advances…

Incremental Generalized Discriminative Common Vectors for Image Classification

Subspace-based methods have become popular due to their ability to appropriately represent complex data in such a way that both dimensionality is reduced and discriminativeness is enhanced. Several recent works have concentrated on the discriminative common vector (DCV) method and…

Efficient point enumeration for sphere decoding in digital communications

An efficient Schnorr-Euchner enumeration (SEE) to perform sphere decoding (SD) in digital communication applications is proposed. In this paper, we devise the elaboration of the enumeration step and counting the visited valid points in order to improve SEE procedure. Compared…

On the performance analysis of cooperative vehicular relaying in LTE-A networks

We investigate the performance gains of a transmission scheme in LTE-A networks where vehicles act as relaying cooperating terminals. The advantages of vehicular relaying networks are the abundant energy and computing power, the predictable mobility patterns of vehicles, and the availability of information from positioning systems…

A Message Suppression Controller for Vehicular Delay Tolerant Networking

In this paper, we propose a Message Suppression Controller (MSC) for Vehicular Delay TolerantNetworking (VDTN) under highly stressed environment. The simulations for two scenarios are conducted considering obstacles (buildings), where MSC with Road side units (MSCRs) are present or not present. We consider…
