chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. this work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). using glas...

introduction: capnography, is an easy, fast and practical method which its application in the diagnosis of pulmonary thromboendarterectomy (pte) has recently been studied. this study aimed to assess the diagnostic value of end-tidal co2 (etco2) and the alveolar dead space (avds) in the diagnosis of patients suspected to pte who have been referred to the emergency department. materials and metho...

The paper describes the construction of a lexical transducer for Korean tha t can be used for s temming a n d generation. The method contains two innovations: (1) two h.'vel rules ms well-formedness constraints in the initial phase; (2) the combinat ion of intersection and composit ion of rule t ransducers in a dee[) cascade ['or the final re.suit.

Multireceiver authentication codes allow one sender to construct an authenticated message for a group of receivers such that each receiver can verify authenticity of the received message. In this paper, we give a formal dee-nition of multireceiver authentication codes, derive information theoretic and combinatorial lower bounds on their performance and give new eecient and exible constructions ...
