Aim We report a case of congenital pulmonary airway malformation (CPAM) with hydrops in which the fetus underwent thoracoamniotic shunting. Case Report A 40-year-old (G1P1) woman was diagnosed with a macrocystic CPAM. Thoracoamniotic shunting was performed at 19 weeks of gestation but not well drained and was successfully performed again at 23 weeks. However, the CPAM volume ratio, abdominal ...
Purpose: The importance of developing automatic speed control systems for hump-shunting diesel locomotives is demonstrated. Using as an example a shunting locomotive Type TEM7A mathematical description provided electric power transmission final controlling element the system and train object. A flow-chart generated system’s principle operation designed so to ensure main requirements are met. PI...
This paper proposes different algorithms to tackle the Generalized Train Unit Shunting Problem (G-TUSP). is pre-operational problem of managing rolling stock in a station, between arrivals and departures. It includes four sub-problems: Matching Problem, Track Assignment Routing Maintenance Problem. In our algorithms, we consider combinations for integrated or sequential solutions these sub-prob...
