This project shows a simplified design and modelling process of Boost Converter specific to photovoltaic (PV) systems. Boost Converter is necessary to upgrade the low, variable output voltage of the PV panels to one compatible with application to the load or energy-storage systems. The proposed technique is applicable in ensuring a successful voltage regulation and optimum flow of power by integrating analytical modelling, simulation and real practical design issues. Inductors and capacitors are optimized precisely to meet critical parameters in the case of solar electricity applications such as duty cycle, switching frequency, and inductors and capacitor sizes. Simulation results verify the performance of the converter to a number of different load conditions and irradiance conditions. The process offers a simple yet effective basis of designing power converters that are high efficient in renewable energy systems.

Here, the morphological image analysis is applied to screen the size and shape of leukocyte cell nucleus. In order to diagnose hematological illnesses, and monitor immunological reactions the nuclei of leukocytes should be properly diagnosed. The methodology uses sophisticated image processing algorithms to stained blood smear images to measure the size of the nucleus and determine form characteristics such as normalcy, uniformity, and circularity of the nucleus. Our automated phase contrast system is more accurate and faster than manual examination in analyzing the leukocyte in addition to reducing the bias observer impact. The results prove that the system has the capability of effectively distinguishing between the morphologies of normal and aberrant leukocytes, which aids in early illness diagnosis. The proposed screening tool brings a great contribution to the clinical diagnosis because it allows performing correct and repeatable measurements of morphological images and provides the estimates of leukocyte nuclear morphology.

The proposed algorithm by this work is an efficient cloud scheduling algorithm that maximizes energy conservation through broadcasting-based procedures. The technique will reduce power use of cloud systems and will lower unnecessary data transmissions by scheduling jobs in a smart course and taking into account facilitated communication. It enhances system efficiency because regardless of the prevailing workload conditions, it dynamically shifts resource allocation as changes occur. Simulation reveals that there is a significant saving in energy with no compromise on the completion time of jobs when compared to the traditional scheduling methods. This program effectively limits the overall energy of cloud data centers with load balance and broadcast optimization. This plan helps in sustainable data center functioning and reduces operating expenses that gives them a viable alternative in cloud computing which is energy efficient. By designing energy-saving approaches to job management, greener cloud architecture so gets promoted by the proposed scheduling scheme.

In a bid to enhance the performance of antennas, this paper presents a circular disc monopole microstripfed antenna with damaged waveguide structures which are constructed and analysed. By incorporating artful application of waveguide imperfections, the proposed antenna would aim at delivering wideband features as well as improvement of radiating properties. The electromagnetic simulation indicates that damaged structure of the waveguides can also lead to a better impedance matching and bandwidth. Experimental data confirms the validity of the simulation; it shows an improved gain and constant radiation patterns in the whole operation range of frequency. The compact size of the antenna, high bandwidth and efficiency renders the antenna suitable to a variety of wireless communication applications. When all is considered, a circular disc monopole microstrip-fed antenna integrated with damaged waveguide structures is a new alternative of maximizing antenna performance with maintaining a simple low profile design.
