The cell contains highly dynamic structures exploiting physical principles of self-organisation at the mesoscale (100 nm to 10 μm). Examples include non-membrane bound cytoplasmic bodies, cytoskeleton-based motor networks and multi-scale chromatin organisation. The challenges of mesoscale self-organisation were discussed at a CECAM workshop in July 2014. Biologists need approaches to observe hi...

To observe nuclear magnetic resonance, the sample nuclei are first aligned in a strong magnetic field. In this experiment, you will learn the techniques used in a pulsed nuclear magnetic resonance apparatus (a) to perturb the nuclei out of alignment with the field and (b) to measure the small return signal as the misaligned nuclei precess in the field. Because the return signal carries informat...

Maximum Power Point Tracking (MPPT) is necessary for Solar Photo Voltaic (SPV) system. Many algorithms such as Perturb and Observe, Incremental conductance and hill climbing are available to track the maximum power. But they have disadvantages such as high cost, diffi cult to implement and instable. Artifi cial Neural Network (ANN) is suitable for handling non-linearites, uncertainties and para...

Photo voltaic based distributed generation system has seen a wide spread interest in research community because of growing energy needs. For efficient distributed generation system, a PV cell is connected with a DC-DC converter and DC-AC inverter. Maximum power point tracking (MPPT) algorithm is used to extract maximum power from the PV cell. There are different MPPT algorithms such as perturb ...

Talagrand’s positivity principle, Section 6.6 in [8], states that one can slightly perturb a Hamiltonian in the Sherrington-Kirkpatrick model in such a way that the overlap of two configurations under the perturbed Gibbs’ measure will become typically nonnegative. In this note we observe that abstracting from the setting of the SK model only improves the result and does not require any modifica...

In modern time the demand of electric energy widely increases day by day due to the reduction of the fossil fuels like (gases, liquids, coals, oil etc.) and the other environmental issues the all of world is looking for the alternative. The solar energy is the most renewable and sustainable energy sources. This paper present Simscape based modeling and performance of the photovoltaic generator ...

Power from solar panel is affected by insolation and temperature variation which can be minimized by MPPT system. In this paper to extract maximum power from solar system, perturb and observe technique of MPPT is used. A PV system require proper battery charge controller to balance the power flow from PV system to battery and load such that photovoltaic power is utilized effectively. In this bu...

This paper presents the modeling of a photovoltaic (PV) module at varying atmospheric conditions such as irradiation and temperature. It also includes the maximum power point tracking (MPPT) of the PV module using conventional perturb and observe (P&O) method and fuzzy logic controller. For the performance analysis, the simulation of the PV module along with MPPT controller is done by using MAT...
