Multistage successive interference cancellation (SIC) and multistage parallel interference cancellation (PIC) are compared under two different realistic dual rate asynchronous DS-CDMA schemes. The effect of power control and imperfect channel side information are also considered. Multistage SIC outperforms singleor multi-stage PIC for any conditions considered.

The objective of this study is to determine the significant predictors endometrial cancer using accelerated failure time models (AFTM). We have demonstrated applications AFTM viz. Exponential, Weibull, Log-normal, Log-logistic, Gompertz, Gamma and Generalized AFTM, as an alternative Cox proportional hazard model. Data for analysis was collected from Acharya Harihar Post Graduate Institute Cance...

one of the most important problems of the designs proposed by traditional economic-statistical approaches of control charts is inefficiency in the face of uncertainty. uncertainty in the parameters of economic-statistical models may lead to failure in rapidly detecting changes in processes and impose greater costs to the organization. monitoring the machining process in an automotive industry e...

The goals of this study were to determine if the muscle contributions to vertical and fore-aft acceleration of the mass center differ between crouch gait and unimpaired gait and if these muscle contributions change with crouch severity. Examining muscle contributions to mass center acceleration provides insight into the roles of individual muscles during gait and can provide guidance for treatm...

Nowadays, motion control systems in industry are designed with fixed PLrPID cascade control loops. These control loops do not take into account the dynamic load variations that occur in many systems. Therefore, as the dynamics of the process inevitably varies, they fall out of tune, which causes the performance and stability to degrade. Also, time delays often arise in motor control systems, bo...

This paper deals with the position control of Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) without linear velocity measurements. We propose a multistage constructive procedure, exploiting the cascade property of the translational and rotational dynamics. More precisely, we consider the force as a virtual control input for the translational dynamics, from which we extract...
