This paper investigates the problem on simultaneously estimating the velocity and position of the target for range-based multi-USV positioning systems.According to the range measurement and kinematics model of the target, ORANGE we formulate this problem in a mixed linear/nonlinear discrete-time system.In this system, the input and state represent
In this article, a simulation model of an autonomous PVdiesel power supply (PDPS) system with direct current is considered.The autonomous PDPS is implemented in the Simulink programming environment of Rocking Chair the Matlab software package.The system includes: a photovoltaic power station (PPS), a diesel generator (DG), an energy storage system
Metoprolol has been widely used for controlling high blood pressure, preventing myocardial reinfarction, setting rate changes, setting heart rhythm, treatment of chronic angina and preventing excessive bleeding during surgery.The purpose of this research is formulation and manufacture of extended release tablets of metoprolol succinate that conform
Mechanical seals are mechanisms that are used to prevent Digital Picture Frame fluid leakage.Since the seal surfaces are in contact with one another, hydrodynamic and contact forces are functions of surface roughness.Additionally, since the lubrication regime under specific operating conditions such as low speed or high load causes the seal to oper
