SUMMARY:Xuan Gu (Tyler) - Modified Earthquake Olami-Feder-Christensen Model
	 with Low Noise\, Asperities and Inhibitions
DESCRIPTION:Featuring Xuan Gu\n\nPart of the PhD Final Oral Exams.\n\nExami
	ning Committee:\n\nWilliam Klein\, Harvey Gould\, Anatoli Polkovnikov\,Robe
	rt Carey\, Rama Bansil\n\n\nAbstract:\n\nAn important class of physical sys
	tems is those that are driven dissipated. One such system is the Olami-Fede
	r-Christensen (OFC) model which was proposed as a model for earthquake faul
	ts. Previous investigations have shown that the OFC model can be described 
	by equilibrium methods under certain circumstances. This observation has ex
	plained several aspects of the OFC model and earthquake faults. However\, t
	hese studies were done at a relatively high level of noise and for systems 
	with a high degree of homogeneity. But real earthquake faults have a very l
	ow level of noise and a large degree of inhomogeneity. In this work\, a car
	eful study of the noise and its relation to the stress transfer range\, dis
	sipation parameter\, and system size is performed. In addition\, a modified
	 form of the OFC model is studied\, where we added asperities. We carefully
	 examined the effect of the asperities on various statistical properties of
	 the model.\n\n![Xuan](/resources/event-image/1562/4f211a5_small)
