Preprocessing Approach for Power Transformer Maintenance Data Mining Based on k-Nearest Neighbor Completion and Principal Component Analysis

International Transactions on Electrical Energy Systems, 2022
The accuracy of a knowledge extraction algorithm in a large database depends on the quality of the data preprocessing and the methods used. The massive amounts of data that we collect every day are putting storage capacity at a premium.

Design and Characterization of a Traveling-Wave Antenna for Millimeter Applications in the Sub-THz Band

International Journal of Antennas and Propagation, 2023
The main challenge in manufacturing antennas in the sub-THz band is their small size, which requires adapted manufacturing tools. This paper proposes a uniform linear 3 × 1 traveling-wave antenna array (ULTWAA) for millimetre applications in the sub-THz ...

Agent based modeling of energy networks [PDF]

, 2014
Attempts to model any present or future power grid face a huge challenge because a power grid is a complex system, with feedback and multi-agent behaviors, integrated by generation, distribution, storage and consumption systems, using various control and

Many Molecular Properties from One Kernel in Chemical Space [PDF]

, 2015
We introduce property-independent kernels for machine learning modeling of arbitrarily many molecular properties. The kernels encode molecular structures for training sets of varying size, as well as similarity measures sufficiently diffuse in chemical ...

N=2 supersymmetry partial breaking and tadpole anomaly

Nuclear Physics B, 2015
We consider the U(1)n extension of the effective N=2 supersymmetric U(1)×U(1) model of arXiv:1204.2141; and study the explicit relationship between partial breaking of N=2 supersymmetry constraint and D3 brane tadpole anomaly of type IIB string on Calabi–

Experimental Energy and Exergy Analysis of an Automotive Turbocharger Using a Novel Power-Based Approach

Energies, 2021
The performance of turbochargers is heavily influenced by heat transfer. Conventional investigations are commonly performed under adiabatic assumptions and are based on the first law of thermodynamics, which is insufficient for perceiving the ...
