This document describes a student capstone project to design a commercially feasible LED driver circuit of less than 15 watts. The project members are listed. The existing LED driver models have low efficiency and poor power factor and high import costs. The goals of this project are to design a higher efficiency driver using an IC with active power factor correction and protections. In the second trimester, the team powered up the IC, designed a preliminary circuit, and developed a working prototype. Their design uses a buck topology for higher efficiency and power factor compared to existing models.

It then provides details on the architecture of GSM networks, including the mobile station (mobile equipment and SIM card), base station subsystem (BTS, BSC, TRAU), network switching subsystem (MSC, VLR, HLR, EIR), and introduces the UMTS network architecture.
Commercially feasible low cost led driver circuit (15 watt)
The document presents the design of a low-cost, locally producible LED driver circuit with high efficiency. The circuit was designed to have low manufacturing costs, comparable efficiency to existing products (up to 80%), and long lifespan. It operates on 220-230V AC input and outputs 61V DC to power LED lights. The circuit design, component values, prototype development, cost analysis, and technical specifications are described. The conclusions discuss the circuit's commercial feasibility for household lighting applications due to its low price, high power factor, and increased efficiency compared to existing solutions.
Commercially feasible low cost led driver circuit (15 watt)
This document summarizes a student capstone project to design a commercially feasible LED driver circuit of less than 15 watts. The project was completed by a group of 4 students. Their design focused on creating a low-cost circuit that maintains constant current and monitors temperature. Their buck converter topology achieved 72.4% efficiency, lower than existing flyback designs, at a manufacturing cost of 34.7 Taka per unit. Future work could focus on increasing efficiency further and adding smart features like sensors.

Wh pwr systems
The document discusses the major systems and components of a pressurized water reactor (PWR) nuclear power plant. There are two main systems - the primary system which transfers heat from the reactor fuel to steam generators, and the secondary system which uses this heat to generate steam and power the turbine. The primary system consists of the reactor vessel, steam generators, reactor coolant pumps, pressurizer and connecting piping. It transfers heat from the fuel to create steam in the steam generators to power the turbine. There are over 100 support systems to enable these functions, as well as emergency systems to handle accidents.

How to Create a More Engaging and Human Online Learning Experience Wahiba Chair Training & Consulting
Wahiba Chair's Talk at the 2024 Learning Ideas Conference. LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
