Control and limitation of harmonic current emission from new customer installations is essential for maintaining supply voltage distortions below the prescribed compatibility or planning levels, and is also required for ensuring electromagnetic compatibility. At the planning stage, emissions of low-order harmonic current are evaluated based on several assumptions and simplifications related to, e...
Conventional approaches to semantic segmentation are inappropriate for robotic applications, as they focus on pixel-level performance and give little significance to spurious object detections. This paper presents a region-based conditional random field model for semantic segmentation that focuses on object-level performance, recognising that in a robotics context, false object detections can have...
The quality of optical signals is a very important parameter in optical communications. Several metrics are in common use, like optical signal-to-noise power ratio (OSNR), Qfactor, error vector magnitude (EVM) and bit error ratio (BER). While the BER is the final determinant for a system, a measured raw BER is not necessarily useful to predict the final BER after soft-decision forward error correction...
Power is a critical resource in sensor networks, especially when the nodes are un-tethered and used in long running applications. Many approaches have been developed to exploit the inherent space and time redundancy in the data collected by sensor networks by using selective querying. In selective querying, at any given time, only a percentage of the nodes is queried; the rest are put in sleep mode...
