Energy consumption optimization scheme in UAV-assisted MEC system based on optimal SIC order by Wei JI, Xuxin YANG, Fei LI, Ting LI, Yan LIANG, Yunchao SONG

“…In uplink non-orthogonal multiple access (NOMA)-based unmanned aerial vehicle (UAV)-assisted mobile edge computing (MEC) system, the successive interference cancellation (SIC) order of NOMA became a bottleneck limiting the transmission performance of task offload in uplink link.To reduce the energy consumption of the system, the SIC order was discussed and the optimal SIC order based on channel gain and task delay constraint was proposed.The optimization problem of minimizing the system energy consumption was proposed based on the optimal SIC order while satisfying the constraints of the given task delay of the device, the maximum transmit power constraint of the device, and the UAV trajectory.Since the problem was a complex non-convex problem, an alternating optimization method was adopted to solve the optimization problem to achieve power allocation and UAV trajectory optimization.A low-complexity algorithm based on matching theory was proposed to obtain the optimal device grouping in different time slots.Simulation results show that the optimal SIC order can realize smaller system energy consumption under the same task delay constraint compared with other SIC order, the proposed low-complexity device grouping algorithm can obtain the optimal device grouping.…”

LIVER EXPLANATION TECHNOLOGY OPTIMIZATION by Александр Сергеевич Разумов, Григорий Валерьевич Вавин, Алексей Владимирович Будаев, Игорь Александрович Радионов, Ольга Дмитриевна Сидорова, Е. Е. Ставицкий, Дарья Александровна Раева, Ф. А. Будаев, Вадим Гельевич Мозес

“…In comparison with the traditional method of liver explantation, the proposed technique had the following differences: the mobilization of the stomach and intestinal loops was performed with their displacement to the left and down, which provided optimal access to the mesenteric veins and the posterior (inferior) vena cava; portal vein catheterization was performed through the anterior mesenteric vein, which reduced the risk of catheter expulsion; liver extraction was performed as part of the liver-diaphragm complex using clamps on the diaphragm, which reduced the risk of organ trauma; The washing of the vascular bed of the liver from the blood began even before the complete completion of the mobilization of the organ and ended almost immediately after its extraction, which reduced the duration of primary ischemia. …”
