The MonoPrep Pap Test (MPPT; MonoGen, Lincolnshire, IL) is a novel, liquid-based specimen collection and processing technology for cytologic and molecular testing. Its usefulness in the detection of cervical cancer and its precursors was evaluated in a multicenter, masked, adjudicated, split-sample study of 10,739 samples. After preparation of a conventional smear, the residuum on the collectio...

Photovoltaic systems normally use a maximum power point tracking (MPPT) technique to continuously deliver the highest possible power to the load when variations in the isolation and temperature occur, Photovoltaic (PV) generation is becoming increasingly important as a renewable source since it offers many advantages such as incurring no fuel costs, not being polluting, requiring little mainten...

Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...

The maximum power point tracking (MPPT) controller in the Photovoltaic system is the key to verify all kinds of MPPT control algorithms. But the development of actual controller has the defects of needing long periods, artificial code writing and so on. RT-LAB real-time simulation platform is an advanced model-based engineering design and test application platform. The outstanding real-time per...

The development of Møller–Plesset perturbation theory (MPPT) has seen four different periods in almost 80 years. In the first 40 years (period 1), MPPT was largely ignored because the focus of quantum chemists was on variational methods. After the development of many-body perturbation theory by theoretical physicists in the 1950s and 1960s, a second 20-year long period started, during which MPn...

Maximum power point tracking (MPPT) is one of the key functions of the solar power management system in solar energy deployment. This paper investigates the design of fuzzy-logic-based solar power MPPT algorithms using different fuzzy input variables. Six fuzzy MPPT algorithms, based on different input variables, were considered in this study, namely (i) slope (of solar power-versus-solar volta...

Maximum Power Point Tracking (MPPT) algorithms are used in PV system to maximize the output power. In this paper MPPT algorithm is implemented using Ćuk converter in PV system. The dynamics of photovoltaic system is simulated at different solar irradiance and cell temperature and is validated by using Perturb and Observe (P&O) method in Maximum Power Point Tracking algorithm.

The maximum power point tracking (MPPT) in photovoltaic (PV) systems varies depending on the fluctuation of the solar radiation and temperature; while the energy transfer from the PV to the load is controlled by specific algorithms. Conventional techniques for MPPT (Perturb and observe (P&O)) are easy to implement but they suffer from oscillations at MPP and speed is less due to fixed perturb s...

Many maximum power point tracking (MPPT) algorithms have been developed in recent years to maximize the produced PV energy. These algorithms are not sufficiently robust because of fast-changing environmental conditions, efficiency, accuracy at steady-state value, and dynamics of the tracking algorithm. Thus, this paper proposes a new random forest (RF) model to improve MPPT performance. The RF ...
