MODELING AND SIMULATION OF ROTOR FLUX OBSERVER BASED INDIRECT VECTOR CONTROL OF INDUCTION MOTOR DRIVE USING FUZZY LOGIC CONTROL

The indirect vector controlled inductor motor (IM) drive involves decoupling of the stator current into torque and flux producing components. This paper proposes the implementation of fuzzy logic control scheme applied to a two d-q current components model of an induction motor. A Fuzzy logic Controller is developed with the help of knowledge rule base for efficient and robust control. The performance of Fuzzy Logic Controller is compared with that of the PI controller with rotor flux observer in terms of the settling time and dynamic response to sudden load changes. The harmonic pattern of the output current is evaluated for both fixed gain proportional integral controller and the Fuzzy Logic based controller. The performance of the IM drive has been analyzed under steady state and transient conditions. Simulation results of both the controllers are presented for comparison

A UNIQUE ENERGY THE LEADERS ABILITIES FOR SUN ARRANGED PV-DRIVEN SRM

In this undertaking a clever energy the board capabilities for sun oriented PV-driven SRM for EVs is executed. By and large to keep away from and diminish the emanation of green house gases this framework is presented. For the utilizations of electric vehicles Exchanged hesitance engines (SRMs) utilized most broadly. To diminish the dependence on batteries of vehicles, photovoltaic boards are utilized. Consequently the methodology is constrained by utilizing tri pot converter which will stream the energy from board, battery, and SRM. In this there are absolutely six working modes, in that four are utilized for driving reason and two are utilized to charge the board. In these P&O (Irritate and notice) MPPT strategies is utilized to control the proposed framework. It halt the charging modes, a framework associated charging geography is created without a requirement for outer equipment. At the point when the PV board straightforwardly charges the battery, a multi segment charging control technique is utilized to streamline the energy usage

Performance of PIXE Technique through a Geochemical Analysis of High Grade Rocks

It has been an argument that some of the elements present in geological material by using PIXE analysis are purely determined or could not be determined at all, due to various reasons including the matrix. It is felt that a systematic investigation needs to be designed and implemented to understand the limitation of PIXE in certain elements. The high-grade rocks selected are analyzed both by PIXE as well as AAS and the results are authenticated by using a USGS reference material, Basalt, studies of literature. It is believed that the accuracy of problematic elements, especially from high grade rock can be improved and the conditions of PIXE can be standardized for various elements under different combinations. The reasons behind the poor performance of Proton Induced X- ray Emission in case of certain elements have been established

IMPLEMENTATION OF AN AUTOMATIC LPGGAS DETECTION AND ALERT SYSTEM

Gas leakage is a major problem with industrialsector and residential premises. The safety workenvironment is important for every worker in theindustries, hotels, restaurants etc. and important tocreate a safer workplace. Gas accidents are vitalissues for all areas of life where precautions arevery important. One of the preventive methods tostop accident associated with the gas leakage is toinstall gas leakage detection kit at vulnerableplaces. The aim of this project is to present such adesign that can automatically detect, stop and alertgas leakage in vulnerable premises. Therefore animplementation of an automatic LPG gas detectionand alert system is proposed in our project. Proposed design can help us to avoid Gasleakage kind of problem in our daily life. The aimof this project is to monitor for liquid petroleum gas(LPG) leakage to avoid fire accidents providing safety feature where security has been animportant issue. The system detects the leakageofthe LPG using gas sensor and alerts the consumerabout the gas leakage by sending SMS

Analysis of Practical Constraints using Hybrid Cuckoo Search Algorithm

In this paper a proposed Hybrid Cuckoo Search Algorithm (HCSA) is used to solve optimal power flow problem. The evolutionary techniques are based on the randomness of the values within its variable limits. Hence choosing best starting solution value and obtaining best final solution within less number of iterations is one of the challenging tasks. In this the conventional Cuckoo Search Algorithm (CSA) is combined along with the real coded Genetic Algorithm (GA) cross over operation to improve the effectiveness of solution. In reality solution of objective optimal power flow with satisfying equality and inequality constraints along with additional constraints of ramp-rate limit and prohibited operating zone limits (POZ) needs a lot of practice. The complete procedure is solved on IEEE-30 bus systems with the supporting result

Analysis of Optimal Power Flow using Hybrid Fruitfly Algorithm

In this paper, hybrid fruit fly algorithm is proposed to find the optimal solution for optimal power flow (OPF) problem in a power system. The proposed approach is applied to determine the optimal settings of control variables of the OPF problem. The performance of the proposed approach examined and tested on the himmelblau test function and 30-bus test systems with different objective functions and is compared to other heuristic methods reported in the literature recently. Simulation results obtained from the proposed approach indicates that HFFA provides effective and robust high-quality solution for the OPF problem

Advanced health monitoring system development and implementation for real-time applications

In the modern world, health monitoring systems are crucial. This system's purpose is to use sensors to measure the patient's body's biological parameters, such as temperature, heart rate, and oxygen saturation. The LM-35 temperature sensor is used to measure temperature. A pulse sensor is used to calculate heart rate. The associated registered number will automatically get an SMS using GSM when the oxygen level thresholds change. Arduino compares the patient's parameters to the values inside the usual range, and if the parameters are out of range, an SMS is automatically sent over GSM to the relevant registered number. The parameters are shown on an LCD screen

The political, research, programmatic, and social responses to adolescent sexual and reproductive health and rights in the 25 years since the International Conference on Population and Development

Among the ground-breaking achievements of the International Conference on Population and Development (ICPD) was its call to place adolescent sexual and reproductive health (ASRH) on global health and development agendas. This article reviews progressmade in low- and middle-income countries in the 25 years since the ICPD in six areas central to ASRH-adolescent pregnancy, HIV, child marriage, violence against women and girls, female genital mutilation, and menstrual hygiene and health. It also examines the ICPD's contribution to the progress made. The article presents epidemiologic levels and trends; political, research, programmatic and social responses; and factors that helped or hindered progress. To do so, it draws on research evidence and programmatic experience and the expertise and experiences of a wide number of individuals, including youth leaders, in numerous countries and organizations. Overall, looking across the six health topics over a 25-year trajectory, there has been great progress at the global and regional levels in putting adolescent health, and especially adolescent sexual and reproductive health and rights, higher on the agenda, raising investment in this area, building the epidemiologic and evidence-base, and setting norms to guide investment and action. At the national level, too, there has been progress in formulating laws and policies, developing strategies and programs and executing them, and engaging communities and societies in moving the agenda forward. Still, progress has been uneven across issues and geography. Furthermore, it has raced ahead sometimes and has stalled at others. The ICPD's Plan of Action contributed to the progress made in ASRH not just because of its bold call in 1994 but also because it provided a springboard for advocacy, investment, action, and research that remains important to this day.
