Ride comfort is increasingly important for automobile companies due to the increasing concern of demands customers. Response shock at low speed, such as single or consecutive pulse excitations from humps, are one greatest assessing indices vehicle ride related comfort. This paper aims study effect driveline bushing on vibration when experiences excitation and improve quality by optimizing param...

We derive a class of localized solutions of a 2+1 nonlinear Schrödinger (NLS) equation and study their dynamical properties. The ensuing dynamics of these configurations is a superposition of a uniform, “center of mass” motion and a slower, individual motion; as a result, nontrivial scattering between humps may occur. Spectrally, these solutions correspond to the discrete spectrum of a certain ...

In this paper we explore how the total effort spent on software development projects is distributed over different development disciplines over time. In particular, we focus on projects that employ modelbased development practises. We present empirical data that was collected from 20 industrial software development projects. We discuss how the pattern that emerges from these industrial data set...

Abstract When the accreting white dwarf in a magnetic cataclysmic variable star (mCV) has field strength excess of 10 MG, it is expected to synchronize its rotational frequency binary orbit frequency, particularly at small separations, due steep radial dependence field. We report discovery an mCV (SDSS J134441.83+204408.3, hereafter J1344) that defies this expectation by displaying asynchronous...
