Boundary Feedback Trajectory Tracking Control Of Rigid Bodies With Interior Shallow-Water Sloshing

Autor: M. Jokar, H. Salarieh, H. Nejat Pishkenari

Publikováno v: مهندسی مکانیک شریف, Vol 39.3, Iss 2, Pp 83-91 (2023)

The problem of tracking control is addressed for rigid bodies with interior shallow-water sloshing. The liquid motion is modeled by the Saint-Venant equations, coupled with the ODE of the rigid body, leading to a global system with an ODE-hyperbolic

We report an observation of ultrahigh-energy (UHE) gamma rays from the Galactic center (GC) region, using 7 yr of data collected by the High-Altitude Water Cherenkov (HAWC) Observatory. The HAWC data are best described as a point-like source (HAWC J1

Spontaneous retrograde urolithiasis migration in a woman: a case report and possible mechanism

Autor: T. Saliba, H. Salame, D. Tack

Publikováno v: Počki, Vol 11, Iss 3, Pp 181-184 (2022)

Urolithiasis is a condition which is commonly encountered in practice, however retrograde migration of a calculus within the ureter has only recently been documented with few cases reported in the literature. We present the case of a 47-year-old woma
