In this paper, we propose a new metric index, called M-tree, which is a tree dynamically organized for large datasets in metric spaces. The proposed M-tree takes full advantages of M-tree and MVP-tree, with a new concept called key dimension, which effectively reduces response time for similarity search. The main idea behind the key dimension is to make the fanout of tree larger by partitioning...
The aims of this project were to evaluate whether early orthodontic treatment with the Twin-block appliance for the developing Class II Division 1 malocclusion resulted in any psychosocial benefits. This multicenter trial was carried out in the United Kingdom, with 174 children aged 8 to 10 years with Class II Division 1 malocclusions randomly allocated to receive treatment with Twin-block appl...
Two-parameter quantum algebras, twin-basic numbers, and associated generalized hypergeometric series
We give a method to embed the q-series in a (p, q)-series and derive the corresponding (p, q)-extensions of the known q-identities. The (p, q)-hypergeometric series, or twin-basic hypergeometric series (different from the usual bibasic hypergeometric series), is based on the concept of twin-basic number [n]p,q = (p n−qn)/(p−q). This twin-basic number occurs in the theory of two-parameter quantu...
The concept of managing a thermal power plant using hybrid digital twin is considered, as well the obstacles that arise during digitalization in energy sector
limb bud first appears during the third week of gestation with the upper limb buds appearing a few days before the lower limb buds. complete absence of one or more limbs, called amelia, occurs prior to the eighth week of gestation. we report a case of amelia in a twin gestation.
In a signal processing like application, the performance of the whole processing is a function of how fast the FFT operation is done .The speed of the operation is directly dependent on efficiency of the multiplier in the design. The paper discusses about a multiplier implementation where the speed of computation is improved by using twin-precision scheme and row decomposition schemes. To lower...
This paper introduces a simple alternative to the hash-and-sign paradigm, from the security point of view but for signing short messages, called twinning. A twin signature is obtained by signing twice a short message by a signature scheme. Analysis of the concept in diierent settings yields the following results: { We prove that no generic algorithm can eeciently forge a twin DSA signature. Alt...
Kerr nonlinearity imposes a limit on the achievable transmission performance and capacity of optical fibre communication links. We show that the nonlinear distortions of a pair of phase-conjugated twin waves are essentially anticorrelated, so cancellation of signal-to-signal nonlinear interactions can be achieved by coherently superimposing the twin waves at the end of the transmission line. We...
We introduce the concept of a digital twin by using Stieltjes differential equations. A precise mathematical definition solution to problem is presented. also analyze existence and uniqueness solutions, main twin. As particular case, classical compartmental SIR (susceptible, infected, recovered) epidemic model considered we study interrelation between system. In doing so, use derivatives feed d...
Abstract The digital twin concept has developed as a method for extracting value from data, and is being new technique the design asset management of high-value engineering systems such aircraft, energy generating plant, wind turbines. In terms implementation, many proprietary software solutions have been marketed in this domain. contrast, paper describes recently released open-source framework...
