A hybrid Genetic Algorithm for Vehicle Routing Problem with Time Windows

The Vehicle Routing Problem with Time Windows (VRPTW) consists of a homogenous set of vehicles and a set of customer located in a city. In VRPTW all the vehicles starts from the depot visit the customer and end at the depot. Each customer is visited exactly by one vehicle within the specified time window. The […]

Impact of BS antenna number and array geometry on single-user LTE-A data throughputs in realistic Macro and Pico cellular environments

This paper evaluates the theoretic performance of single-user multi-stream beamforming for heterogeneous LTE-A urban deployments (i.e. Macro and Pico cells). The work investigates the impact of six different Base Station (BS) antenna configurations on system level capacity. Our standard configuration assume 8 BS and 8 User Equipment (UE) antenna elements. To enhance capacity the BS […]

Hybrid Method for 3-D Gaze Tracking Using Glint and Contour Features

Glint features have important roles in gaze-tracking systems. However, when the operation range of a gaze-tracking system is enlarged, the performance of glint-feature-based (GFB) approaches will be degraded mainly due to the curvature variation problem at around the edge of the cornea. Although the pupil contour feature may provide complementary information to help estimating the […]

Design of Thermally Poled Twin-Core Fiber Coupler With Electrical Tunability

Tunable coupler based on thermally poled twin-core fiber (TCF) with a hole-core-core-hole configuration was proposed in this letter. The thermal poling process therein was investigated based on the 2-D charge dynamics model. Effective χ(2) in the twin-cores pointing toward opposite directions were introduced. By subjecting the poled TCF to modulating voltage, the tunability of coupling ratio […]

Genetically Engineered Bacteria-Based BioTransceivers for Molecular Communication

Molecular Communication (MC) is a nano-scale communication paradigm where the information is carried by molecular signals. To establish information transmission using molecules, biological nanomachines can be utilized as transmitters and receivers. A bacteria can be programmed as a biotransceiver by modifying their genetic code to implement biological circuits. In this paper, genetically engineered bacteria-based biotransceivers […]

Managing your privacy in mobile applications with MockingBird

Mocking is a standard technique in software testing; its main goal is to mimic the real object behavior in a controllable way. Recently, mocking techniques have been used in mobile environments to increase the user privacy and their goal is to allow users to select the kind of information they want to pass to the […]

An m-health system for the estimation of voice disorders

In recent years, the prevalence of voice disorders has been increasing dramatically, mainly due to unhealthy lifestyles and voice abuse. An impairment in the ability to produce the sound of the voice is indicated by the medical term Dysphonia. This disorder impacts on the quality of life of the population in general, but especially of […]

Cost-Effective Authentic and Anonymous Data Sharing with Forward Security

Data sharing has never been easier with the advances of cloud computing, and an accurate analysis on the shared data provides an array of benefits to both the society and individuals. Data sharing with a large number of participants must take into account several issues, including efficiency, data integrity and privacy of data owner. Ring […]

An experimental study on the statistical properties of radio environment noise

We study the statistical characteristics of radio environment noise, in particular focusing on spurious received power arising from adjacent channel interference, harmonics and wideband man-made interference. Unlike the majority of existing studies, our measurements enable a comprehensive study on frequencies ranging from 80MHz to 2.64 GHz instead of being focused on the properties of an […]

Block-wise equaliser in fast fading channels

In fast fading channel, for reducing detection complexity, a nearly banded channel is adopted in many literatures. For the sake of designing a nearly banded channel perfectly, the authors deduce the relationship between the bandwidth of the nearly banded channel matrix and normalised Doppler frequency shift under certain power of negligible intercarrier interference (ICI) coefficients.
