A Digital Twin is a digital replica of living or nonliving physical entity, and this emerging technology attracted extensive attention from different industries during the past decade. Although few studies have been conducted in transportation domain very recently, there no systematic research with holistic framework connecting various mobility entities together. In study, twin (MDT) developed,...

A new concept for a high-speed data decision with a feedback loop for cancellation of intersymbol interferences (ISI) is proposed. Operation up to over 20 Gbit/s has been measured. The improved speed performance has been obtained by a new concept merging the parallel principle and a twin DC references approach.

The Twin Paradox is one of the most well known and debated paradoxes associated with Relativity theory. Opponents challenge Relativity theory on the grounds that the Twin Paradox reveals an underlying flaw in the theory. Such opponents feel that the existence of a paradox, in and of itself, is sufficient to disqualify the theory. Supporters explain the paradox by introducing the concept of acce...

We present a proof-of-concept experiment to realize microwave primary power standard with a true-twin microcalorimeter. Double feeding line microcalorimeters are widely used by National Metrology Institutes. A drawback concerns the system calibration: traditional processes changes measurement conditions between system characterization and the measurement stage. Nevertheless, if the feeding line...

The subject of this research is the development a digital twin for process mixing components gas mixture in mixer generator. problem motivated by concept digitalizing modern production and considered relation to technology question generating given composition homogeneity. A gas-dynamic model an unsteady flow has been constructed numerical study carried out using Ansys Fluent software. Reduced ...

Twin research has supported the concept of intelligence (general cognitive ability, g) by showing that genetic correlations between diverse tests of verbal and nonverbal cognitive abilities are greater than 0.50. That is, most of the genes that affect cognitive abilities are highly pleiotropic in the sense that genes that affect one cognitive ability affect all cognitive abilities. The impact o...

Ultrasound has revolutioned the care of women carring twins. First trimester evaluation is the best time to determine chorioniocity and amnioniocity in multiple gestations. First trimester diagnosis is based on the number of gestational sacs, amnions and yolk sacs. Growth rate in multiple multiple gestations during the fist and early second trimesters parallels the growth rate of singleton preg...

In this paper, we propose a novel high-dimensional index method, the BM-tree, to support efficient processing of similarity search queries in high-dimensional spaces. The main idea of the proposed index is to improve data partitioning efficiency in a high-dimensional space by using a rotary binary hyperplane, which further partitions a subspace and can also take advantage of the twin node conce...
