This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...

In this paper we study the decidability of reachability, normalisation, and neededness in n-shallow and n-growing TRSs. In an n-growing TRS, a variable that occurs both on the leftand right-hand side of a rewrite rule must be at depth n on the left-hand side and at depth greater than n on the right-hand side. In an n-shallow TRS, a variable that occurs both on the leftand right-hand side of a r...

this paper elaborates on persian and english orthographic shared aspects to study the effects of l1 persian on learning english as a foreign language. while there are some examples of letter and sound mismatches in the orthographic system of both languages, those of english are more complex than persian. in order to see the effect of the mismatch between orthography and transcription, 40 persia...

This study describes the dependence of the surface electric field to the junction depth of source/drain-extension, and the suppression of gate induced drain leakage (GIDL) in fully depleted shallow junction gate-overlapped source/drain-extension (SDE). The GIDL can be reduced by reducing shallow junction depth of drain-extension. Total space charges are a function of junction depth in fully dep...

The water cushion depth of stilling basin with shallow-water cushion is a key factor that 13 affects the flow regime of hydraulic jump in the basin. However, the specific depth at which the 14 water cushion is considered as “shallow” has not be stated clearly for now, and only conceptual 15 description is provided. This paper attempts to specify the best water cushion depth based on the 16 flow...

The depth and fluctuation of shallow groundwater influence water supply to land surface vegetation. Knowledge of an ecologically ideal depth range of shallow groundwater for a vegetation ecosystem can be crucial for sustainability of regional water resource management and ecological conservation. In this study, we developed a conceptual model that identifies an upper and a lower boundary of sha...

The study on physiochemical factors and primary production of the aquatic ecosystems is important to know the characteristic of environment and capacity of recharge. Mahshahr creeks are the most important creeks in Khuzestan, Iran. In this study, variations in physiochemical factors, chl-a and primary production in 3 regions (Mahshahr, Zangi, and Moussa entrance creeks) were evaluated in 2 mont...
