The IPIN 2019 Indoor Localisation Competition—Description and Results

IPIN 2019 Competition, sixth in a series of IPIN competitions, was held at the CNR Research Area of Pisa (IT), integrated into the program of the IPIN 2019 Conference. It included two on-site real-time Tracks and three off-site Tracks. The four Tracks presented in this paper were set in the same environment, made of two buildings close together for a total usable area of 1000 m 2 outdoors and and 6000 m 2 indoors over three floors, with a total path length exceeding 500 m. IPIN competitions, based on the EvAAL framework, have aimed at comparing the accuracy performance of personal positioning systems in fair and realistic conditions: past editions of the competition were carried in big conference settings, university campuses and a shopping mall. Positioning accuracy is computed while the person carrying the system under test walks at normal walking speed, uses lifts and goes up and down stairs or briefly stops at given points. Results presented here are a showcase of state-of-the-art systems tested side by side in real-world settings as part of the on-site real-time competition Tracks. Results for off-site Tracks allow a detailed and reproducible comparison of the most recent positioning and tracking algorithms in the same environment as the on-site Tracks

Accurate Analysis Method and Voltage Gain Curve Derivation Algorithm Based on Time-Domain Analysis for High-Efficiency LLC Resonant Converter Design

An accurate analysis method for an LLC resonant converter and a time-domain analysis (TDA)-based voltage gain curve derivation algorithm are proposed in this paper. When applied to an LLC resonant converter, the TDA method can obtain high-accuracy current and voltage waveforms by solving nonlinear equations for circuit parameters through operation-mode analysis. An LLC resonant converter operating mode classification algorithm was proposed based on the results of this analysis. The circuit voltage and current values in the steady state were quickly and precisely derived using this algorithm. An accurate power-loss analysis is required to design a high-efficiency converter. Therefore, TDA is a powerful tool for designing an LLC resonant network. The proposed TDA-based LLC resonant converter analysis and voltage gain curve derivation algorithm provides high-accuracy voltage, current value estimation and voltage gain curves for all switching-frequency ranges. The effectiveness of the proposed algorithm is verified using a 500 W LLC resonant converter prototype experiment

Role of Grounded Liquid Collectors in Precise Patterning of Electrospun Nanofiber Mats

Liquid collectors are applicable as ground collectors in electrospinning, which fabricates complex nanofiber architectures. However, the influence of the electrical properties of liquid collectors on the controlled deposition of electrospun nanofiber mats has received little attention. Here, we prepare two types of liquid collectors (electrolyte solutions and dielectric liquids) and newly scrutinize their roles in the patterning of electrospun nanofiber mats in experiments and in numerical simulations. By simulating the concentrations of the electric fields around the liquid collectors, we indirectly evaluated the patternability of the collectors. The patternability trends were verified by the patterning of nanofiber mats on line-array-shaped liquid collectors fabricated by electrospinning. The deposition accuracy of the electrolyte solution collector was very high, equivalent to that of a conventional metal collector even at low salt concentrations (e.g., 0.01 M KCl). However, the nanofiber mats fabricated by electrospinning with the dielectric liquid collector showed retarded patternability.111Nsciescopu
