In this study, different disc brakes and friction materials are evaluated with respect to particle emission output characteristic features derived. The measurements take place on an inertia dynamometer using a constant volume sampling system. Brake wear factors of concepts in sizes determined compared, grey cast iron disc, tungsten carbide-coated carbon ceramic disc. were tested over section (t...

This paper shows how to generate an English step-bystep explanation that describes how an automated reasoning system solves a complex constraint program. We study programs that solve tabular-constraint problems encoded in Constraint Lingo and then translated into propositional logic with cardinality constraints. We instrument the logic solver so that it generates log files. We inspect those log...

Neurotrophins, essential regulators of many aspects of neuronal differentiation and function, signal via four receptors, p75, TrkA, TrkB and TrkC. The three Trk paralogs are members of the LIG superfamily of membrane proteins, which share extracellular domains consisting of leucine-rich repeat and C2 Ig domains. Another LIG protein, LINGO-1 has been reported to bind and influence signaling of p...

We determine, for the first time, reactivity of ground brake pads with ozone and discuss potential impact this interaction on urban air quality.

We present a fraction-free approach to the computation of matrix Pad e systems. The method relies on determining a modiied Schur complement for the coeecient matrices of the linear systems of equations that are associated to matrix Pad e approximation problems. By using this modiied Schur complement for these matrices we are able to obtain a hybrid fraction-free algorithm for their computation....

In this chapter we present the design and optimization of GPU implementations of two popular chemical similarity techniques: Gaussian shape overlay (GSO) and LINGO. GSO involves a data-parallel, arithmetically intensive iterative numerical optimization; we use it to examine issues of thread parallelism, arithmetic optimization, and CPU-GPU transfer overhead minimization. LINGO is a string simil...

An online evolving clustering (OEC) method equivalent to ensemble modeling is proposed tackle prognostics problems of learning and the prediction remaining useful life (RUL). During phase, OEC extracts predominant operating modes as multiple clusters (EC). Each EC associated with its own Weibull distribution-inspired degradation (survivability) model that will receive incremental modifications ...

Braking forces occurring during emergency brake applications of passenger trains are generated by disc units. The acting friction depend on the frictional properties between and pad influenced relative velocity, temperatures normal pressure contacting surfaces. In this work a mathematical model is developed which aims to link these influencing variables instantaneous coefficient in order includ...
