One of Hungary's strategic water sectors is the supply drinking water, which relies heavily on so-called riverbank filtration systems. About 35-40% national comes from filtered aquifers. Today in Hungary, 40% population; nearly four million people's daily needs are met In future, 75% our sources will be bank-filtered, means that they also great importance for future resource management. The mai...

Constructing an accurate geological model of the reservoir is a preliminary to make any reliable prediction reservoir’s performance. Afterward, one needs simulate flow predict dynamic behaviour. This process usually associated with high computational costs. Therefore, alternative methods such as percolation approach for rapid estimation efficiency are quite desirable. study tries address Well T...

During the development of oil and gas fields, permeability reservoirs decreases due to a decrease in reservoir pressure an increase effective pressure, as result which significant reserves remain reservoir. To predict rate production rates during field respond quickly, it is necessary know law with pressure. Existing methods for describing change rocks were analyzed paper. Numerical analysis re...

Logical expressions are often used to formalize software specifications of safety-critical systems. These logical expressions can be tested using software testing methods (criteria) that include Decision Coverage (DC), Condition Coverage (CC), Decision/Condition (D/CC), and Modified Condition/Decision Coverage (MC/DC). Selection of the appropriate testing method is an important practical task. ...
