Research on the minimum network loss optimization control strategy of the active distribution network based on the distributed power flow controller

Frontiers in Energy Research
With large-scale access to distributed new energy, the power flow form of the distribution network tends to be complex. The distribution loop network rate increases, resulting in serious circulation of the distribution network, which places significant ...

Solution of thixotropic model parameters during shutdown and restart of gelled crude oil in loop

You-qi chuyun, 2020
Thixotropy, an important index to measure the low-temperature fluidity of waxy crude oil, is crucial to the hydraulic characteristics and safety of gelled crude oil during pipeline shutdown and restart. In the existing process of solving the parameter of

Loop-mediated isothermal amplification (LAMP) test for detection of Trypanosoma evansi strain B [PDF]

, 2010
Camel Trypanosomiasis (Surra) is mainly caused by Trypanosoma evansi strains that express variable surface glycoprotein (VSG) RoTat 1.2 However, in Kenya a second causative strain that does not express RoTat 1.2 VSG (T. evansi type B) has been identified.

Closed parasitic flow loops and dominated loops in networks [PDF]

International Journal of Operational Research, 2019
The paper raises awareness of the presence of closed parasitic flow loops in the solutions of published algorithm for maximising the throughput flow in networks. If the rooted commodity is interchangeable commodity, a closed parasitic loop can effectively be present even if the routed commodity does not physically travel along a closed loop. The closed

Experimental Study of Flow-induced Pressure Fluctuations in Horizontal Straight Pipes with Single- and Two-phase Flow

한국해양공학회지
Pressure fluctuations caused by multiphase flow in piping systems can lead to structural vibration, noise generation, and potential damage to the piping infrastructure. This study examined flow-induced pressure fluctuations and their spatial distribution
