OBJECTIVE To compare vaginal anatomy and sexual function after the conventional posterior and anterior sacrospinous vault suspension. METHODS A retrospective repeated measures cohort study included all 168 consecutive sacrospinous vault suspension procedures between July 1990 and February 1997. The posterior suspension (n = 92) used a posterior vaginal incision and pararectal dissection. Ante...

To improve the vehicle performance such as ride comfort and road handling, the active suspension system should be used. However, the current active suspension system has a high energy consumption therefore reducing the fuel economy. In this paper the vibration excited by road unevenness is treated as a source of mechanical energy. It is being converted into electrical energy to compensate for t...

The paper presents the virtual prototype of an automotive suspension system with force generator actuator. The active suspensions use sensors to measure the accelerations of sprung mass and unsprung mass, the analog signals from the sensors being transmitted to the controller, which communicates with the force actuator. In this way, the passenger comfort and car stability are simultaneously imp...

In this paper, a successful approach for the vibration analysis of quarter car suspension system using random and step function road profiles, by developing a new graphical user interface (GUI), has been introduced. The main objective of the paper is to show the usefulness and power of Malab GUI in modeling and analyzing dynamic behavior of quarter car suspension system. The second purpose of t...

In this paper an H∞ controller is designed for a hydraulically actuated active suspension system of a half-modeled vehicle in a cascade feedback structure. Using the proposed structure the nonlinear behavior of actuator is reduced significantly. In the controller synthesis, a proportional controller is used in the inner loop, and a robust H∞ controller forms the outer loop. Two H∞ controllers a...

A common mode of limb suspension for transtibial amputees is the pin liner/shuttle lock system. Despite its popularity, some clinicians question its use because of observed daily and chronic changes to the residual limb. For this study, we measured limb interface pressures during ambulation with pin and suction suspension systems. No pressure differences were seen between the modes of suspensio...

OBJECTIVE To review the outcomes of hyoid myotomy and suspension with a mandibular screw anchoring device. STUDY DESIGN Case series with chart review. SETTING Academic and private sleep surgery clinics. METHODS The study is a consecutive case series of patients undergoing hyoid myotomy and suspension using a mandibular screw suspension device as part of multilevel treatment of obstructive...

An optimal Fractional Order PI λ D μ (FOPID) controller is designed for a full vehicle nonlinear active suspension system. The optimal values of FOPID controller parameters for minimizing the cost function are tuned using an Evolutionary Algorithm (EA), which offers an optimal solution to a multidimensional rough objective function. The fitness parameters of FOPID controller (proportional const...

in recent years, more attention has been paid on intelligent vehicle suspension systems equipped with magneto-rheological dampers. in order to investigate nonlinear vehicle dynamics, in the majority of the researches, a quarter-car model with one or two degrees of freedom is used. in such simple models, one can only study the bounce motion of sprung and unsprung masses. in this paper, in order ...

Control of vehicle suspension systems has been the focus of extensive work in the past two decades. Many control strategies have been developed to improve the overall vehicle performance, including both ride quality and stability conditions. In this paper, we use the H∞ and mixed H2/H∞ techniques with a semi active suspension system to increase the passenger’s ride comfort performance A two deg...
