1. INTRODUCTION
In the future, the cost of energy will increase due to environmental problems and limited resources. The electric motor consumes major part of the electric energy in the industry. The induction motor is the main driven system in the modern industrial society. It would also reduce the production of greenhouse gases and push down the total environmental cost of electricity generation. Also these motors can reduce maintenance costs and improve operation in industry. Energy efficient motors use less electricity, run cooler, and often last longer than NEMA (National Electrical Manufacturers Association) B motors of the same size.
Motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Inefficient electric motors waste electrical energy and therefore cost more to operate. Since most electricity is generated from fossil-fuelled power plants, motors and motor-driven systems are also indirect contributors to greenhouse gas emissions produced by these plants. Hence, there are compelling economic and environmental reasons to increase the use of energy efficient motors.

With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and

people. And it is widespread used in many developed
countries. The merits of the solar and wind power

Overview
Lighting and Appliances
Making the lighting and appliances in a home more energy efficient is an important part of the weatherization process. Exchanging inefficient light bulbs for newer, energy efficient versions is easy and, in most cases, inexpensive.
Exchanging appliances for newer, more energy efficient ones is usually worth the effort, although some appliances, such as ovens and stovetops, do not use enough energy to warrant being replaced.
Learning Objectives
Upon completion of this module, you should be able to:
7A
evaluate the best types of artificial lighting.
7B
create different applications that bring natural light in a space.
7C
discuss which types of appliances are the most energy efficient.

Lecture Notes
Lighting and Appliances
Anything that draws electrical power is referred to as a load. Part of weatherizing a home includes minimizing the loads in the home in order to lower energy bills and maximize energy efficiency.
Artificial Lighting
Artificial lighting is provided by electricity, fixtures, and bulbs. Artificial lighting is a big contributor to high energy costs. It can contribute as much as 50 percent of the total energy costs of a home.
Lynn Clement of Focus on Energy once said, “If every American household replaces light bulbs in their five most frequently used fixtures with ENERGY STAR compact fluorescent bulbs, we could save more than $8 billion in annual energy costs and prevent greenhouse gases equal to the emissions of more than 10 million cars.”
Since lighting accounts for 20 to 25 percent of U.S. energy consumption, the move to more energy efficient lighting is very important.
Types of Lighting
There are three primary uses, or functions, for lighting in homes: task, ambient, and accent. Task lighting provides light to perform work. Ambient lighting may include light that is used for work but also includes lighting for safety and security. Any lighting used for contrast or ambiance is accent lighting. There are many different types of artificial lights available for residential uses.
Types of Artificial Lighting
Incandescent
Fluorescent
Compact fluorescent
High-intensity discharge
Halogen
Light Emitting diodes
Full Spectrum
Recessed Lights
Incandescent Bulbs
Incandescent bulbs, which are also referred to as A-type bulbs,.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
