The stabilization of homogeneous bilinear systems constitutes the main interest of this paper. A sliding mode control is suggested and a stability study is held leading to sufficient conditions of global stabilization. The sliding surface is determined through the resolution of the nonlinear constraints of stabilization. Simulations on numerical examples are presented proving the effectiveness ...

Pilates and resistance exercises are used for lumbar stabilization training. However, it is unclear which exercise is more effective for lumbar stabilization. In our study, we aimed to compare surface muscle activity and deep muscle thickness during relaxation and spinal stabilization exercise in experienced Pilates and resistance exercise instructors. This study is a retrospective case control...

An ideal colloidal system should be highly stable in a diverse range of buffer conditions while still retaining its surface accessibility. We recently reported that dispersing citrate-capped gold nanoparticles (AuNPs) in polymers, such as polyethylene glycol (PEG), can achieve such a goal because of contributions from depletion stabilization. Because AuNPs can weakly adsorb PEG to exert steric ...

sewage stabilization pond is recommended as one of the economical methods for sewage treatment particularly in dry areas of the world and those places which are in shortage of water and income deficit, this method can be used for treatment of sewage in rural areas, small towns and even large cities. sewage stabilization pond system does not require technical equipment and specialists, and efflu...
