The aim of the present study was to develop nanoproliposomes of lercanidipine, in order to overcome its poor biopharmaceutical properties and to improve its therapeutic efficacy in treating hypertension.The nanoproliposomes were prepared using a modified thin-film hydration method, and the formula was optimized by varying the ratio of lipids and the types of cryoprotectants. This optimized formulation...
To control the temperature inside the furnace, a PID control algorithm is implemented through a user-defined function (.udf). A Computational Fluid Dynamics (CFD) simulation of direct-resistance heating furnace is carried out using commercial computational modeling and simulation software- Ansys Fluent. To achieve a response with fewer oscillations, small overshoot and settling time, the controller...
This paper presents application of incremental conductance using platform of fuzzy logic for solar photovoltaic (PV) system. Incremental conductance (IC) is one of the conventional maximum power point tracking (MPPT) algorithm. Conventional algorithm brings drawbacks in terms of ripples and accuracy of the output power generated by PV system. Using IC based fuzzy logic attenuates the problems present...
The Acid solution formation plant consists of mainely two equipments centrifuge and vessel. Control system of plant includes contol of instruments associated with these two equipments. The process of acid formation is a batch process. This paper gives information about implementation of a batch control system for acid solution formation plant using APROL distributed control system (Linux based DCS)...
Maximum power point tracking (MPPT) is an key component of photovoltaic system so as to maximise the energy under given specified condition. Perturb and observe (P&O) and incremental conductance(IC) are two popular conventional control algorithm because of the simplicity in design. In this work, comparisons between these two conventional algorithms are carried out. These algorithms are implemented...
Many organizations, at some point or another, have to face a crisis situation. In that scenario, the way in which the organization communicates makes or breaks the organization’s success in dealing with the crisis. Especially after the emergence of the social media, the impact of crisis communication on the process of successful crisis management has become even greater than before. Organizations...
To utilize the maximum amount of solar energy application of maximum power point tracking must be employed in PV systems. The trait of a solar cell is non-linear in nature. The intensity of the solar radiation falling on the earth surface relies on various parameters like clouds, water vapor, pollution, absorption, scattering and in climatic factors. A PV system without MPPT hardly produces maximum...
This paper presents design and simulation of Perturb and Observe (PO) algorithm of Maximum Power Point Tracking (MPPT) for Photo voltaic system. The characteristics of a solar cell are dependent on the environmental parameters like sun light and temperature and are non linear in nature. It's power changes non linearly with respect to the voltage and current. Hence there is only one voltage and current...
This paper presents the modeling of Photo Voltaic (PV) module using the two different approach using MATLAB/Simulink. The modeling is based on the two diode model of solar cell. Two approaches are used to simulate the PV module, the first is based on the available Simulink library of simscape/simelectronics and second is based on the simulation PV cell current and voltage equations in Simulink environment...
A solar tracker is a device which always faces sun throughout the day and 365 days a year. It is mainly used to track maximum energy from the Photo voltaic panel. In this paper, a three dimensional solar tracker has been implemented, which utilizes the sensor made with four LDRs (Light Dependent Resistors). Here a special arrangement of LDRs has been used which will enhance the working range of the...
