A novel magnetic ion exchange resin called MIEX Resin is being utilized in potable water treatment, which indicates significant advantages. The objective of this article is to analyze characteristics and application of MIEX Resin in engineering projects, and hence provide critical review on merits and demerits of the resin. Furthermore, researches on combination of MIEX Resin with other water treatment technologies would be analyzed and discussed to prove potential that a MIEX Resin process integrated with other treatments can be employed in broader fields of wastewater treatment and reuse.

Actuator is a very important part of vehicle active control suspension. Based on the analyses of traditional passive suspension and active suspension system, a novel vehicle active suspension with Electro-Hydrostatic Actuator (EHA) is put forward. The system consists of two parts: spring and actuator with variable control force. The actuator includes hydraulic cylinder, hydraulic pump, controller, etc. According to bond graph principle, bond graph model of EHA active suspension are built. In addition, sky-hook controller and fuzzy logic controller are designed and sky-hook control and fuzzy control active suspension are simulated using MATLAB tools. The prototype and test rig of EHA active suspension are developed and bench tests are carried out. The simulation and experimental results show that sky-hook control and fuzzy control active suspension with EHA provide better ride comfort and stability than passive suspension system.

Seat suspension is one of a most important part of a vehicle, also it significantly affects the comfortableness of cars. Compared with traditional dampers, magneto-rheological ones can achieve the condition with continuous adjustable damping force. Compared with electro-rheological fluid, magneto-rheological ones have some merits including noise defending, large damping forces and fast response etc. Based on magneto-rheological dampers, the structural parameters were calculated and characteristic test was conducted. Constant amplitude of 5mm and frequency of 1hz were applied. As the current was respectively changing, the peak of damping forces changed correspondingly. In order to figure out a model, which can illustrated the influence of damping force on current, researchers also identify the magneto-rheological dampers using support vector regression. In this paper, research related with fuzzy control of seat-suspension system has been done by using a Matlab simulation model, so as to verify the damping forces can be adjustable and it has priority on vibration attenuation.
