Heavy-Tailed Probability Distributions: Some Examples of Their Appearance

Heavy-tailed distributions, such as Pareto's law and Lotka's law, are characterized by their propensity to produce extreme values more frequently than distributions with lighter tails, like the normal distribution. In social sciences, these distributions often describe phenomena where a small number of occurrences account for a large proportion of the effect, such as wealth distribution or scienti...

Novel Screen System Improvement Methodology for Flood and Diffuse Pollution Control: Demonstration via a Case Study

Screen systems are often neglected in practice. This can lead to local flooding, pollution of receiving watercourses, blockages of channels by debris, and safety problems for children playing. The aim of this case study is therefore to protect below-ground channels and people, prevent flooding, improve water quality, and save personnel costs through a new screen system maintenance, repair,...

Design of CRLH-TL BPF with controllable attenuation poles

AbstractCompact and pole-controllable resonators and bandpass filter (BPF) using a composite right/left-handed transmission line (CRLH-TL) are designed in this study. The distributed constant line in the CRLH-TL has applied a tap-coupling technique, and one tap-coupled stub is loaded with the left-handed (LH) circuit. Attenuation poles are generated when the input ...

Design of PFC converter with stand-alone inverter for microgrid applications

AbstractThe proposed topology is used to connect a single-phase and a three-phase renewable energy resources to the grid. The single-phase source is coupled to a single-phase PFC boost converter, which enhances the input PF utilizing two feedback loops: outer voltage loop control and inner current loop control. The basic hightlight is to study the PFC converter in ...
