OBJECTIVE To evaluate the value of early identification and endovascular treatment of iliac vein compression syndrome (IVCS), with or without deep vein thrombosis (DVT). MATERIALS AND METHODS Three groups of patients, IVCS without DVT (group 1, n = 39), IVCS with fresh thrombosis (group 2, n = 52) and IVCS with non-fresh thrombosis (group 3, n = 34) were(More)
Most previous research is only focus on the actuators placement problem in structures vibration control, however the acting force’s effect direction always has been ignored, obviously, if piezoelectric actuator can effect in a better direction, a better effective result would be taken. The problem of piezoelectric actuators locations and(More)
