Wheel/rail contact simulation is one of the most complicated problems in the modeling of railway vehicles. The wheel/rail interaction plays a unique role in rail vehicle dynamics. In this paper, the dynamic response of the wheel on irregular rail track is analyzed with analytical approach using the method of Multiple Scales (MMS). The Hertzian contact theory is used to obtain the relationshi...

Treatment of waste water containing ethylene glycol (EG) by implementing a sequence of two Moving Bed Biofilm Reactors (MBBR) were studied. Reactors were operated at different hydraulic retention times (HRT) of 48, 24, 18, and10 hours while EG concentration was in the range of 10 mg/l to 1,150 mg/l. Throughout the experiments the ratio of EG Chemical Oxygen Demand (COD) to total COD was changed...

Within the decision support system area of research, there is a growing body of work focusing on the topic of Model Management (MM). This paper proposes extending the concept of a Model Management System (MMS) to function within and exploit the capabilities of a distributed computing environment. A framework for research in Distributed MMS (DMMS) is discussed. In this framework, distribution of...

Protein acetylation modification has been implicated in many cellular processes but the direct evidence for the involvement of protein acetylation in signal transduction is very limited. In the present study, we found that an alkylating agent methyl methanesulfonate (MMS) induces a robust and reversible hyperacetylation of both cytoplasmic and nuclear proteins during the early phase of the cell...

Neural retinas of 6-day-old chick embryos synthesize DNA and are able to carry out DNA excision repair. However, in contrast to the situation in human cells, the maximum rate of repair induced by N-acetoxy acetylaminofluorene (AAAF) is no greater than that induced by methyl methanesulfonate (MMS). With advancing differentiation of the retina in the embryo, cell multiplication and DNA synthesis ...

This paper presents a real time digital simulator based test system as a new method for testing microgrid management system (MMS). This system is composed of a real time digital simulator and a developed communication emulator. Real time digital simulator runs a simulation case for microgrid model and distributed generation source model. Communication module emulates communication functions of ...

We characterize the equilibria of a dynamic model of electoral competition under alternative voting rules. Electoral competition is modeled as a dynamic extension of a standard probabilistic voting model in which public debt is a state variable creating a strategic linkage across electoral cycles. In any given state of the economy, a proportional system (PS) generates stronger incentives to pro...

We calculate electromagnetic mass difference of mesons using a method proposed by Duncan et al. The RG-improved gauge action and the non-compact Abelian gauge action are employed to generate configurations. Quark propagators in the range of mPS/mV = 0.76− 0.51 are obtained with the meanfield-improved clover quark action. Chiral and continuum extrapolations are performed and the results are comp...

This article presents the research and development activity on the Modular Monitoring System (MMS), a low-power wireless modular architecture for Structural Health Monitoring (SHM) introduced in [1]. The MMS is a device capable to easily interface the vast majority of sensors employed in SHM thanks to a novel modular architecture. In addition, the low-power design allows the MMS to support long...

Adenotonsillar hypertrophy is a major cause of obstructive sleep apnea (OSAS) in childhood. Increased respiratory effort associated with OSAS is accompanied by an increase in pulse transit time (PTT) but also mandibular movements (MMs) amplify with increased upper airway resistance. We compared dynamic changes in PTT and MMs using a magnetic distance sensor during polysomnography (PSG) in a pre...
