wettability alteration is an important method for increasing oil recovery from oil-wet carbonatereservoirs. chemical agents like surfactants are known as wettability modifiers in carbonate systems.oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wetto water-wet condition with adding dilute surfactant and electrolyte solutions. this paper invest...

One of the most important characteristics of annular arrays is their superior focal capabilities. In order to achieve the desired focussing, each of the elements is fired in different times. The delay times used for beam focussing are called focal laws. The focal laws are automatically calculated from the inspection software. In order to make sure that the focal laws are calculated correctly fr...

Modern production of structural parts in the aeronautic industry is characterized by mechanically optimized structures that can be complicated to inspect due to complex geometries and/or complex materials. Developing NDT procedures is thus more challenging and could become costly without tools to help NDT design and performance predictions. Simulation is a major asset to help engineers to evalu...

In this paper we describe a problem solving system with a learning mechanism (Learning Arithmetic Problem Solver, LAPS), which can solve arithmetic problems written in natural languages. Since LAPS has knowledge about arithmetic problems in the form of rules, it can solve many different problems without alteration of the program. When LAPS cannot solve a given problem because of a shortage of k...
