The document discusses different types of solar collectors and components of flat plate collectors. Flat plate collectors consist of an absorber plate, glass cover, insulation, and enclosure. They work by absorbing solar radiation to heat a fluid flowing through tubes attached to the absorber plate. The performance of collectors is determined by measuring the inlet and outlet fluid temperatures and flow rate. Collector efficiency is the ratio of useful energy gain to incident solar energy. Temperature distributions in collectors and methods for calculating overall heat loss coefficients are also examined.

4 solar collector
Solar collectors convert solar radiation into heat and transfer the heat to a fluid. There are two main types: flat plate collectors and concentrating collectors. Flat plate collectors are simpler and less expensive, while concentrating collectors can reach higher temperatures but are more complex. The key components of flat plate collectors are an absorber surface, glass cover, fluid tubes, and insulation. Concentrating collectors use mirrors or lenses to focus sunlight onto receivers to achieve higher temperatures suitable for steam generation.

The document presents a presentation on flat plate solar collectors. It discusses that flat plate collectors consist of an insulated metal box with a glass or plastic cover and a dark absorber plate. They are able to heat liquid or air to temperatures under 180°F. The key components are the transparent cover, tubes and fins for fluid flow, a metallic absorber plate, insulation, and an enclosing casing. Materials for the different components must have properties like high conductivity, strength and durability. Flat plate collectors are widely used for domestic hot water and some commercial applications like laundromats due to their ability to use both direct and diffuse sunlight without orientation requirements.

This document summarizes the testing and results of a new solar-powered adsorption refrigerator developed by researchers in Switzerland. The refrigerator uses silica gel and water as the adsorption pair, with the silica gel contained in cylindrical tubes that function as both the solar collector and adsorber. Testing from July to September 2001 showed promising performance, with a gross solar cooling coefficient of performance (COPSR) ranging from 0.10 to 0.25, higher than previous solar refrigerators. External parameters like irradiation and temperature influenced the COPSR. Under good solar conditions, the COPSR was as high as 0.23, demonstrating the refrigerator's potential for solar cooling applications without electricity.

Electrostatic precipitator by rajeev saini
The document discusses electrostatic precipitators (ESPs) which remove dust particles from industrial emissions through electrostatic filtration.
ESPs work by ionizing the dust particles in the flue gas stream and collecting them on oppositely charged plates. Negatively charged high voltage electrodes emit corona discharge which charges the dust particles positively. The particles are then attracted to and collected on grounded collecting plates.
Key factors that impact ESP performance include gas temperature and composition, dust resistivity, specific collection area, and aspect ratio of the ESP unit. High resistivity dust like that containing sulfur is more difficult to collect efficiently. Temperature also affects dust resistivity and ESP operation.

Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
