Flat plate collectors consist of an absorber plate and fluid tubes enclosed in an insulated casing to transfer solar heat. Focusing collectors use reflectors to concentrate sunlight onto a smaller receiver area, achieving higher temperatures. Examples of focusing collectors are parabolic troughs, dishes, and power towers which can generate electricity at utility scale. The document also outlines the components of solar thermal systems and provides an overview of solar energy applications.

Solar thermal systems harness solar energy to produce heat that can then be used for applications like generating electricity or providing hot water. They have several advantages over photovoltaic solar cells, as they can absorb nearly the entire solar spectrum and are more efficient. There are different types of solar collectors classified by their concentrating temperature as low-temperature flat plate collectors, medium-temperature line focusing collectors like parabolic troughs, and high-temperature point focusing collectors including central towers. Solar thermal technology has been developed over centuries and is now used commercially around the world to provide electricity, heating, cooling, and hot water in a renewable way with low emissions, though the initial costs are high and they require significant amounts of land and water.

Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Solar water heater ppt
- 1. SOLAR WATER HEATER Presented By: Pushpak Kumawat 12th C
- 2. CONTENT • What is solar water • Schematic diagram • How does it work? • Site selection (Defining the Solar Window) • Site Assessment Solar Window Illustration • Site Assessment Collector Mounting • What are different types of Solar Water Heaters? • Flat Plate Collectors (FPC) based Solar Water Heaters • Evacuated Tube Collectors (ETC) based Solar Water Heaters • What happens on cloudy/rainy day? Do I still get hot water? • Fuel Savings • Environmental benefits • Life & Approximate cost • Advantages / Disadvantages
- 3. WHAT IS SOLAR WATER HEATER? • A Solar Water Heater is a device which provides hot water for bathing, washing, cleaning, etc. using solar energy. • It is generally installed at the terrace or where sunlight is available and heats water during day time which is stored in an insulated storage tank for use when required including mornings.
- 5. HOW DOES IT WORK? • A Solar Water Heater comprises of an array of solar collectors to collect solar energy and an insulated tank to store hot water. • Both are connected to each other. • During the day time, water in solar collectors gets heated which is either pumped or flown automatically on thermo syphon principle to the storage tank. • Hot water then stored in the tank can be used for various applications.
- 6. SITE SELECTION (DEFINING THE SOLAR WINDOW) • Shortest day of the year December 21st • Longest day of the year June 21st • Solar collectors need full sun from 9 AM until 3 PM (FOE 10-2)
- 7. SITE ASSESSMENT SOLAR WINDOW ILLUSTRATION
- 8. SITE ASSESSMENT COLLECTOR MOUNTING
- 9. WHAT ARE DIFFERENT TYPES OF SOLAR WATER HEATERS? • Two types of Solar Water Heaters are available; one based on flat plate collectors and the other based on evacuated tube collectors. Flat plate collector (FPC) based systems are of metallic type and have longer life as compared to Evacuated tube collector (ETC) based system because ETCs are made of glass which are of fragile( can be easily broken or destroyed) in nature. • Both these systems are available with and without heat exchanger. They can also work with and without pump. Systems without pump are known as thermo syphon systems and those with pump are known as forced circulation systems.
- 10. FLAT PLATE COLLECTORS (FPC) BASED SOLAR WATER HEATERS • The solar radiation is absorbed by Flat Plate Collectors which consist of an insulated outer metallic box covered on the top with glass sheet. • Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. • The absorber absorbs the solar radiation and transfers the heat to the flowing water.
- 11. EVACUATED TUBE COLLECTORS (ETC) BASED SOLAR WATER HEATERS • Evacuated Tube Collector is made of double layer borosilicate glass tubes evacuated for providing insulation. • The outer wall of the inner tube is coated with selective absorbing material.
- 12. WHAT HAPPENS ON CLOUDY/RAINY DAY? DO I STILL GET HOT WATER? • On cloudy days also, if it is for a day or two, you still get warm water as water gets heated due to diffused radiation available in the atmosphere. • The system, however, is either connected to an electric geyser in the house or an electrical back-up is provided in the storage tank of the system which is switched on when water is not sufficiently hot • So, you get hot water all the time even on rainy days.
- 13. FUEL SAVINGS : • A 100 liters capacity SWH can replace an electric geyser for residential use and saves 1500 units of electricity annually.
- 14. ENVIRONMENTAL BENEFITS • A SWH of 100 liters capacity can prevent emission of 1.5 tones of carbon- dioxide per year.
- 15. LIFE & APPROXIMATE COST : • A SWH of 100 liters capacity can prevent emission of 1.5 tones of carbon- dioxide per year. • Rs.15000- 20,000 for a 100 liters capacity system and Rs.110-150 per installed liter for higher capacity systems
- 16. ADVANTAGES • Simple to construct and install. • No or negligible running cost. • Almost maintenance free. • Cost is low and economically competitive with electric water heating system. • It saves time and high grade form of electric energy. • Required low temperature up to 100o C can be achieved by simple flat plate collector.
- 17. DISADVANTAGES • Freezing problem • No big problems related to this.
