Abstract A series resistance extraction method proposed recently, which uses multiple drain current versus gate voltage curves at varied voltages, was applied to bulk CMOS devices low temperatures down 4 K. moderate reduction of compared with 300 K found. Horizontal field dependence mobility significantly changed temperature, taken into account during the extraction. Anomalous non-linear observ...

One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...

The use of multilateral well is becoming an emerging method to improve oil recovery efficiently and to drain reservoirs more efficacious. By developing drilling technology, completing the oil wells as multilateral wells become more interesting especially from economic point of view. On the other hand, lack of any means for forecasting the performance of this type of wells causes drilling of...

43 A is an important water management practice in the midwestern United States to remove excess water from poorly drained areas and to provide traffi cable conditions for agricultural production. About 30% of the total land area and 50% of the crop land in Indiana is subsurface drained (Economic Research Service, 1987). Th ere are growing concerns about the potential negative environmental impa...

ABSTRACT: This paper presents the settlement analysis of a beam resting on geosynthetic reinforced granular fill-soft soil system. Each subsystem of the reinforced fill-soil system is idealized by elastic membrane, Pasternak shear layer, Winkler springs and dashpots, as applicable. The suggested model incorporates various aspects of the behavior of the geosynthetic-reinforced granular fill-soft...
