this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even...

An important decision in the development of a mixed oil and natural gas field is whether to produce or re-inject the natural gas. There is a trade-off between the income from the sale of natural gas and the higher oil production obtained from re-injection. We consider the optimal timing problem of when to stop natural gas injection for a set of offshore petroleum fields using a real options app...
