power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. the resonant overvoltages may destroy the insulation between turns and cause to insul...

In this paper, we present a new texture representation of face image using a robust feature from the Trace transform. The masked Trace transform (MTT) offers “texture” information for face representation which is used to reduce the within-class variance. We first transform the image space to the Trace transform space to produce the MTT. Weighted Trace transform (WTT) identifies the tracing line...

An infinite binary sequence is complex if the Kolmogorov complexity of its initial segments is bounded below by a computable function. We prove that a Π01 class P contains a complex element if and only if it contains a wtt-cover for the Cantor set. That is, if and only if for every real Y there is an X in the P such that X >wtt Y . We show that this is also equivalent to the Π01 class’s being l...

In this paper, we numerically study the wave turbulence of surface gravity waves in framework Euler equations free surface. The purpose is to understand variation scaling spectra with wavenumber $k$ and energy flux $P$ at different nonlinearity levels under forcing/free-decay conditions. For all conditions (free decay, narrow- broadband forcing) consider, find that spectral forms approach theor...

Two-party or multi-party typed chatting on social media platforms is becoming a popular object of study in pragmatic research nowadays. Apparently, such very often non-synchronous and non-spontaneous thus arguably not so naturally occurring. However, based close examination some details WeChat talk (WTT) among Chinese, the present seeks to demonstrate that terms organization recontextualization...

The identification of major trauma patients before arrival in hospital allows the activation of an appropriate trauma response. The Wessex triage tool (WTT) uses a combination of anatomical injury assessment and physiological criteria to identify patients with major trauma suitable for triage direct to a major trauma centre (MTC), and has been adopted by the South-West Peninsula Trauma Network ...

Embryonic stem (ES) cells are resistant to transforming growth factor beta (TGF beta). We have shown previously that they lack type-II binding receptors (T beta RII) and in this respect resemble the inner cell mass and ectoderm cells of mouse embryos 4.5-7.5 days post coitum (dpc); they do however express type-I (alk-5) signalling receptors. Here we show that in contrast to several tumour cell ...

We show that in the c.e. weak truth table degrees if b < c then there is an a which contains no hypersimple set and b < a < c. We also show that for every w < c in the c.e. wtt degrees such that w is hypersimple, there is a hypersimple a such that w < a < c. On the other hand we know that there are intervals which contain no hypersimple set.

Steel large-megawatts wind turbines have the light-damping and long-period properties, resulting in adverse vibrations under loads. In this paper, a novel tuned mass damper refitted via inner platform (IP-TMD) is proposed to control excessive vibration of steel turbine tower (WTT). Firstly, dynamic equation WTT controlled by IP-TMD system established according principle virtual work, its coeffi...
