Estimation of Multipath Propagation from Measured Channel Data

Influence of signal-to-noise ratio and point spread function on limits of super-resolution

This paper presents a method to predict the limit of possible resolution enhancement given a sequence of lowresolution images. Three important parameters influence the outcome of this limit: the total Point Spread Function (PSF), the Signal-to-Noise Ratio (SNR) and the number of input images. Although a large number of input images captured by a...

Polarization-insensitive PECVD SiC waveguides for photonic sensing

Planar silicon carbide (SiC) waveguides are proposed for fabrication on a silicon substrate with a oxide isolation layer. Using post deposition annealing it is possible to achieve low Polarization-Dependent Loss (PDL) within optical SiC waveguides fabricated using a low temperature deposition technique. Those waveguides have been successfully...

Performance of optimal registration estimators

This paper derives a theoretical limit for image registration and presents an iterative estimator that achieves the limit. The variance of any parametric registration is bounded by the Cramer-Rao bound (CRB). This bound is signal-dependent and is proportional to the variance of input noise. Since most available registration techniques are biased...

Resolution enhancement of low quality videos using a high-resolution frame

This paper proposes an example-based Super-Resolution (SR) algorithm of compressed videos in the Discrete Cosine Transform (DCT) domain. Input to the system is a Low-Resolution (LR) compressed video together with a High-Resolution (HR) still image of similar content. Using a training set of corresponding LR-HR pairs of image patches from the HR...

Robust Wafer-Level Thin-Film Encapsulation (Packaging) of Microstructures (MEMS) using Low Stress PECVD Silicon Carbide

This paper presents a new low-cost, CMOS-compatible and robust wafer-level encapsulation technique developed using a stress-optimised PECVD SiC as the capping and sealing material, imparting harsh environment capability. This technique has been applied for the fabrication and encapsulation of a wide variety of surface- and thin-SOI...

Ecosystem service monitoring using remote sensing, citizen science and other ground observations and current practices in Vietnam

Ecosystems are providing a stream of essential goods and services for the national socio-economic prosperity and welfare; paradoxically, these services have to suffer a high vulnerability against the increasingly uncontrolled use of human beings. World-wide researchers and authorities are working to ensure the sustainability of nature; and...

Experiences in a Cyber-Physical Co-Simulation Testbed Development for a Smart-er Distribution Network

With the rise of the integration of renewable energy sources, the operating characteristics of existing electric power distribution systems are evolving and changing. As a result, the digitalisation of the distribution network is gaining attention for effective real-time monitoring and control. Cyber-Physical cosimulation is one of the options...

Towards Automation of Configuration Management for Multi-Research Infrastructure Experiments

The complexity and dynamic nature of laboratory configurations pose a challenge when undertaking joint experiments, involving multiple Research Infrastructures (RIs). In this context, this paper presents an approach towards the automation of Configuration Management (CM) for joint experiments between multiple labs. The objective is to develop a...
