This paper presents a detailed analytical model development which can describe the dynamic behavior of the electromechanical brake-by-wire (BBW) system over the entire operating range. The complete model has 10 degree-of-freedom (DOF) and includes essential nonlinearities such as gear backlashes, Coulomb frictions, and disk gap clearance. Such a full model is reduced to 6 degree-of-freedom mode...

A bracket is a function that assigns a number to each monomial in variables τ0, τ1, . . .. We show that any bracket satisfying the string and the dilaton relations gives rise to a power series lying in the algebra A generated by the series nn−1qn/n! and nnqn/n! . As a consequence, various series from A appear in the intersection theory of moduli spaces of curves. A connection between the counti...

Since object-oriented programming is usually associated with iterative development, reverse engineering must be considered an essential facet of the object-oriented paradigm. The reverse engineering pattern language presented here summarises the reverse engineering experience gathered as part of the FAMOOS project, a project with the explicit goal of investigating reverse and reengineering tech...

BACKGROUND To investigate the incidence, clinical presentation and possible etiologies or risk factors of early onset of sudden and unexpected death or near-miss. METHODS From 2001 to 2005, a retrospective analysis of observational database of neonates who were younger than one week old without any risk factors at five tertiary medical centers. The demographic data, clinical manifestations, l...

Enumerating ramified coverings of the sphere with fixed ramification types is a well-known problem first considered by A. Hurwitz [5]. Up to now, explicit solutions have been obtained only for some families of ramified coverings, for instant, those realized by polynomials in one complex variable. In this paper we obtain an explicit answer for a large new family of coverings, namely, the coverin...

background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

introduction emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of autism spectrum disorders (asd). the ratios of the lengths of the bones of the 2nd to the 4th digits (2d:4d) are purported to be markers for prenatal androgen exposure and to be established early in gestation. ratio of second and fourth digits (2d:4d)  is usually used as a proxy for prenatal t...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...

In this paper, we propose a new version of TCPW (TCP-Westwood) to (1) maintain friendliness to widely used protocols, such as TCP-Reno, as well as (2) improve efficiency in mixed wired-wireless networks with non-negligible random packet losses due to link errors. In addition to significant efficiency gains, TCPW has been shown to be unfriendly to existing protocols under certain RTT and/or rout...

Biomass/biomass waste (BBW) is a renewable energy source fired in combustion power plants. However, challenges associated include accelerated ‘fireside’ corrosion of heat exchangers. Fireside fuel dependent, e.g. virgin wood fuels have lower fireside risks; as such their demand and cost high. Waste (WWF) herbaceous grass biomass (HGB), generate different environments, influencing exchanger dama...
