We consider exponential single server queues with state-dependent arrival and service rates that evolve under influences of external environments. The transitions the are influenced by environment’s state movements environment depend on status (bidirectional interaction). is constructed in a way to encompass various models from recent Operations Research literature, where queue coupled an inven...

in this investigation, continuous cooling transformations and microstructures have been studied in detail in a low carbon ti-nb bearing microalloyed steel by means of dilatometry, metallography and hardness measurements. the results indicate that when the cooling rate is greater than 1˚c/s, the dilatation curve is associated with a major dilatation at relatively low transformation temperatures,...

Pharmacies are part of the distribution category drug sales and purchases. The demand for drugs becomes a focal point in customers to drugs. Employees act prepare record purchase orders following month. activity sorting available unavailability supply data often takes long time. Exponential smoothing method is forecasting moving averages by providing easy-to-analyze weighting. Time series with ...

Salah satunuya bagaimana bisa merubah kebiasan tanpa arah menjadi berkemungkinan baik. satunya adalah dengan menggunakan teknik peramalan/ forecasting Peramalan tentunya memberikan gambaran mendekati nilai sesunguhnya akan d...

This paper examines the propagation of M-shape solitons and their interactions with kink waves to (2 + 1)-dimensional integrable Schwarz-Korteweg-de Vries (ISKdV) problem by applying symbolic computation ansatz functions technique logarithmic transformation. The governing model usually appears in nonlinear shallow water fluid mechanics. We discuss various like multiwave solutions (MSs), homocli...
