In this paper, MBOC (Multiplexed Binary Offset Carrier) Signal which is recommended as the optimized modulation on L1 (E1) frequency band by both US and EU sides in the future was studied. This paper carried on the detailed analysis to the new MBOC signal characteristic through the analysis of the power spectral density function. Then two multipath mitigation techniques based on DLL (Delay Lock Loop) — strobe correlator and narrow correlator with basic functionality and implementation were introduced. These two techniques were applied to mitigate the multipath's influence on MBOC signals. Simulation based on Matlab tool was analyzed and the performance was compared with the BOC signals.

This paper presents a new direct discrete variational solution to curve reconstruction from derivatives. The formulation of basis functions and the variational problem in terms of matrix algebra has simplified many proofs; including the χ2 confidence interval surrounding the reconstructed curve. Simultaneous spatial reconstruction and temporal filtering is implemented. The Method is verified via Monte-Carlo simulations and also applied to the real-time monitoring of rail-track subsidence. In this application a string of inclinometers are mounted along the stretch of track where it will be monitored. The curve representing the form of the track is reconstructed from the measured derivatives.

Design and implementation of a modern radar receiver that is capable of rapidly searching a large frequency range with maximum sensitivity in real time presents a challenge. Such a receiver not only has stringent operational requirements like high instantaneous dynamic range (IDR), multiple signal detection capability, wider bandwidth and also high frequency resolution. Currently, operating speeds of digital processors are not on par with state-of-the-art ADCs. To overcome this impediment, researchers are exploring methods of offloading the computational intensive tasks to specialized hardware accelerators. A 3 giga-sample-per-second (GSPS) wideband digital receiver system implemented on a unique hybrid computing platform, which is composed of two Tesla C2050 GPUs and a Xilinx Virtex-5 FPGA, is presented. Drastically improving its performance over its predecessors, the proposed receiver system detects five simultaneous signals in 1.25 GHz bandwidth (125–1375 MHz) with a maximum IDR of 42.5 dB and a frequency resolution of 0.5 MHz. The proposed receiver architecture performs a high-resolution spectral estimation and employs a hardware efficient platform for detecting multiple signals before the next set of buffered data arrives for processing.

This paper introduces a new procedure for the self-calibration of a set of ultrasonic LPSs (Local Positioning Systems), each one of them with a different coverage area. At the end of the process, all the positions of the beacons belonging to the different LPSs are obtained. The method proposed here uses a MR (mobile robot) to automatically take the measurements of distances from the mobile robot position to the different beacons. The process starts considering the pose of the robot on the floor plane at the beginning as the origin of coordinates (being the x-axis the initial direction of the robot in its movement). The procedure implies the following stages: a) a pre-calibration phase in which the MR position is calculated by the onboard dead reckoning and the LPS is calibrated using an inverse positioning algorithm; b) a calibration phase to refine the beacon positions merging the information obtained by both, the dead reckoning and the LPS; c) a navigation phase in which only the MR position is calculated also using the dead reckoning and the LPS (the last depending on the position of the MR inside or outside the coverage area of the LPS); and d) a new LPS calibration if the MR is driven from the first LPS to the new one, repeating the whole process-phases a) to c), and after returning to the initial LPS in order to reduce the errors introduced by the dead reckoning when no LPS correction was available between LPSs. Simulated and real results are presented also to illustrate the performance of the method.

This paper aims to present a method to determine the relative permittivity of vermiculite using a volumetric water content probe. The volumetric water content is important in soil characterization, especially for the determination of water absorption curves. The basic principle of the probe used in this study is the measurement of the refractive index of the soil √ε at 100 MHz to allow the determination of the water content through a known relation between these quantities. In this work, a Profile Probe type PR2 (Delta-T Devices, Cambridge, England) was used. Values of 0.98 and 0.99 for the correlation coefficients were obtained in the experiments showing an accurate relationship between the water content and the dielectric constant of vermiculite. A statistical analysis of the data was also made after the realization of the experiments.

The coil impedance of eddy current sensor depends on sample electromagnetic properties and the displacement between sample and coil, so eddy current sensor can be developed to be a kind of nondestructive evaluation sensor to characterize the integrity of sample as well as a displacement sensor to measure distance or coating thickness. A bottleneck problem for eddy current displacement sensor is the ERO problem, which is caused by the change or uneven distribution of sample conductivity and permeability. The aim of this paper is to investigate the contributions of sample conductivity and relative permeability on ERO problem and present a way to solve the ERO problem in eddy current displacement measurement. Therefore, the relationship of the real and imaginary part of coil impedance with the varied sample conductivity and relative permeability are studied under the different inspections, such as the configuration of coil probe and excitation frequency. According to the investigation, the ellipse distribution of the real and imaginary part of coil impedance with the sample conductivity is proposed to remove the ERO problem after the sample is magnetized to be in saturation.

This paper evaluates the design and testing of an optical voltage transformer (VT) using a fiber Bragg grating (FBG) and a PZT ceramics stack. The application is directed to the power industry to measure voltage in high-voltage distribution lines and can be used as the core of a practical 13.8 kV-Class VT. The sensor consists of a stack of ceramic rings spaced by thin copper discs and an FBG sensor attached to an aluminum support where the stack is fixed. Experimental results indicate linear relationship between voltages applied to the sensor and the displacement of reflective spectrum of FBG in high voltage applications.

The paper describes the use of a dual-wavelength technique for compensating power fluctuations in intensity-based plastic optical fiber sensors for displacement measurements. The sensor consists of a fiber that collects the reflected light from a target and retrieves its distance from the signal attenuation. Besides a measurement signal at 450 nm that travels back and forth the displacement region and is attenuated according to the target position, a compensation signal at 650 nm propagates along the fiber and is back-reflected at the fiber tip by a dichroic filter. The compensation signal undergoes power fluctuations due to environmental stress of the fiber and is therefore used as a reference to correct the measurement signal. A demonstrator, which includes a sensor, the acquisition circuitry and signal processing software, was built and tested in laboratory and proved that the measurement signal is capable of monitoring displacements in the range (0 ÷ 10) mm even at low power, while the reference signal is not influenced by the position of the reflecting target and can therefore be used as reliable reference.

In this paper, a numerical model of aerosol Particle Charge and Size Analyzer is discussed together with the simulation results. In order to determine the optimal range of system parameters, the effect of drive frequency, strength of the electric field, mean flow velocity on the particle count percentage have been investigated based on the specific criteria in sine and square wave excitation fields. The optimal range of system parameters for both excitation methods has been determined with the recommended values proposed for sine and square wave excitation systems.

In this paper we address the challenges and design considerations to add emotional tag to existing Internet-based social network services. We propose an emotion tagger that takes content from diversified Internet-based services and maps the analyzed content to an emotional value which can be used to augment semantic values of Internet-based service. To show a proof of concept working environment, we add the proposed emotion tagger with our earlier developed context-aware social network framework called SenseFace and investigate the efficiency of the tagger. We finally present our preliminary integration results.
