 Abstract

The Internet of Things is a developing topic of social, technical and other branches. This concept is very progressive in the future of the Internet of Things which will transform the real world objects into the intelligent virtual objects. The main aim of the paper is to discuss an automatic extension to the industrial furnace. We discussed the new topic that is the development of the smart furnace by using Internet of things and optimization of that smart furnace with the help of some advance techniques and solutions. BMS is used for safe power generation in process plants. We can safely start and shut-down our burners with the help of a BMS. It includes timer, flame intensity, gas leakage detection. It brings safety to an industry process. We are planning to automate the industrial burner. By using Raspberry Pi we are planning to set a wireless communication. In this paper, we will be discussing about implementing IIoT to our industrial furnace as well developing a mobile application just to analyse our furnace measurements and readings.

 Abstract

Chakrata, Jaunsar-Bawar region is conferred by diverse wealth in terms of flora. The flora is so wealthy just because of the microorganism which inhabits the soil. Pseudomonas fluorescens belongs to the PGPR (plant-growth promoting rhizobacteria), which plays a major role in plant growth promotion and reduce severity of various diseases, bio-control agent as well as antagonist, and a potential biosurfactant producer. A total of six soil samples were collected from different villages of chakrata. Dilutions of soil sample were made and isolated on the nutrient agar medium followed by identification through Gram�s staining and different biochemical analysis. Different tests were performed for each isolated bacterias from different soil samples. Out of which four samples showed the presence of Pseudomonas fluorescens strains according to the Bergey�s manual of determinative bacteriology. Seeds of black-eyed peas(lobia) and okra(bhindi) were treated with isolated strains of P.fluorescens . After treating them, seeds were sown in the pots. A pot as a control is taken for the comparison of growth between inoculated and uninoculated seeds. The inoculated seeds showed positive growth than control. The present study indicates that the presence of Pseudomonas species in soils of chakrata is selective in nature and supports the well growth of selected plants and this is one of the main reasons for the well productivity of different varieties of crops and medicinal plants in chakrata, jaunsar-bawar areas.

 Abstract

Factor, the ratio between the real or average power and the apparent power forms a very essential parameter in power system. It is indicative of how effectively the real power of the system has been utilized. Hence, there is a continuous need for power factor improvement and reduction of line current harmonics. Development of new circuit topologies and control strategies for Power Factor Correction (PFC) and harmonic reduction has become still more essential with the introduction of strong technical IEC standards. This project aims to develop a circuit for PFC using active filtering approach by implementing two boost converters arranged in parallel. It shall be based on an optimised power sharing strategy to improve the current quality and at the same time reduce the switching losses. The work initially involves simulation of basic power electronic circuits and the analysis of the current and voltage waveforms. It starts with simple circuits with a gradual increase in complexity by inclusion of new components and their subsequent effect on the current and voltage waveforms. We focus on the objective of improving the input current waveform i.e. making it sinusoidal by tuning the circuits. All the simulation work is done in MATLAB Simulink environment and the Power results are attached herewith.
