A rate-dependent Prandtl-Ishlinskii model for piezoelectric actuators using the dynamic envelope function

Meiju YANG,Chunxia LI,Guoying GU,Limin ZHU

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 1,   Pages 37-42 doi: 10.1007/s11465-015-0326-1

Abstract:

In this paper, a novel rate-dependent Prandtl-Ishlinskii (P-I) model is proposed to characterize therate-dependent hysteresis nonlinearity of piezoelectric actuators.The new model is based on a modified rate-dependent play operator, in which a dynamic envelope functionThe experimental results show that the developed rate-dependent P-I model precisely characterize therate-dependent hysteresis loops up to 1000 Hz.

Chloride binding and time-dependent surface chloride content models for fly ash concrete

S. MUTHULINGAM,B. N. RAO

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 1,   Pages 112-120 doi: 10.1007/s11709-015-0322-x

Abstract: Corrosion of embedded rebars is a classical deterioration mechanism of reinforced concrete structures exposed to chloride environments. Such environments can be attributed to the presence of seawater, deicing or sea-salts, which have high concentrations of chloride ion. Chloride ingress into concrete, essential for inducing rebar corrosion, is a complex interaction between many physical and chemical processes. The current study proposes two chloride ingress parameter models for fly ash concrete, namely: 1) surface chloride content under tidal exposure condition; and 2) chloride binding. First, inconsistencies in surface chloride content and chloride binding models reported in literature, due to them not being in line with past research studies, are pointed out. Secondly, to avoid such inconsistencies, surface chloride content and chloride binding models for fly ash concrete are proposed based upon the experimental work done by other researchers. It is observed that, proposed models are simple, consistent and in line with past research studies reported in literature.

Modeling temperature and moisture dependent emissions of carbon dioxide and methane from drying dairy

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 2,   Pages 280-286 doi: 10.15302/J-FASE-2018215

Abstract: Greenhouse gas emissions due to biological degradation processes of animal wastes are significant sources of air pollution from agricultural areas. The major environmental controls on these microbe-induced gas fluxes are temperature and moisture content. The objective of this study was to model the effects of temperature and moisture content on emissions of CO and CH during the ambient drying process of dairy manure under controlled conditions. Gas emissions were continuously recorded over 15 d with paired fully automated closed dynamic chambers coupled with a Fourier Transformed Infrared gas analyzer. Water content and temperature were measured and monitored with capacitance sensors. In addition, on days 0, 3, 6, 9, 12 and 15, pH, moisture content, dissolved organic carbon and total carbon (TC) were determined. An empirical model derived from the Arrhenius equation confirmed high dependency of carbon emissions on temperature and moisture content. Results indicate that for the investigated dairy manure, 6.83% of TC was lost in the form of CO and 0.047% of TC was emitted as CH . Neglecting the effect of temperature, the moisture contents associated with maximum gas emissions were estimated as 0.75 and 0.79 g·g for CO and CH , respectively.
