Modification and Testing of Parabolic Concentrator Solar Water Distiller Rese...Siddharth Bhatnagar
The document summarizes the modification and testing of a parabolic concentrator solar water distiller to improve its efficiency and usability. Key modifications included replacing mirrors with reflective aluminum sheets to reduce weight, adding a microprocessor-controlled solar tracking system using a chain drive mechanism to maximize sunlight collection, and adjusting the dish mounting to the local latitude. Testing found the modifications increased annual usable time by 47% and overall efficiency by 23-32% compared to the original design. The updated design provides a portable, low-maintenance solar distillation system, though tracking could be improved with a dual-axis mechanism.

Abstract:
Concentrated Solar Power (CSP) technology is one of the most promising candidate for mitigating the future energy crisis. The extracted power from CSP technology is very clean, reliable and environmental friendly. An overview of CSP technologies like Parabolic Trough, Solar Tower, Parabolic Dish, Linear Fresnel technology have been described in this paper. Comparison among these technologies has been illustrated in this work. For extenuating the present power crisis in Bangladesh CSP technology has great opportunities, since the average Direct Normal Irradiance (DNI) in Bangladesh is 4-6.5 KWh/m 2 which is suitable for all types of CSP technology. Suitable locations for different CSP plants in Bangladesh are also proposed on the basis of efficiency, required area and amount of DNI received.
DOI: 10.1109/ECACE.2017.7913020
Concentrating solar power (CSP) harnesses the sun's energy through technologies like parabolic troughs, power towers, and thermal energy storage. It can generate electricity even when the sun is not shining by storing solar energy as heat. CSP is well-suited for areas with abundant sunlight like India's deserts and is a key technology for providing renewable energy at scale. While CSP projects are currently capital intensive, ongoing research and larger deployments are expected to drive down costs and allow CSP to compete with traditional power sources.

IRJET-Review on Solar Thermal and Photovoltaic Energy SystemIRJET Journal
This document summarizes and compares solar thermal and photovoltaic energy systems. Solar thermal systems indirectly generate electricity by using solar collectors to heat a liquid or gas, then converting the heat to electricity. Concentrated solar power is a type of solar thermal that uses tracking mechanisms to focus sunlight and achieve higher temperatures and efficiencies. Photovoltaic systems directly convert sunlight into electricity using solar panels without heat exchange. While photovoltaic systems have higher energy production, even at low light levels, their limitation is lack of cost-effective electricity storage. Solar thermal systems allow for thermal energy storage at low cost and therefore can provide dispatchable electricity production. Both systems show potential but differ in energy conversion methods and ability to store excess energy
The document is a work report submitted by Vishal Chandrashekhar, a Junior Research Fellow at the Indian Institute of Science in Bangalore, summarizing the projects he worked on during his tenure from August 2013 to May 2014.

IRJET- Ameliorate the Performance of PV Module by Inventing Heat Dissipat...IRJET Journal
This document describes a study that aimed to develop a passive heat dissipation system to improve the performance of photovoltaic (PV) modules. PV module efficiency decreases with higher temperatures, as heat absorbed from solar irradiation is not easily dissipated. The researchers designed a system using aluminum heat sinks attached to the back of a PV module with thermal grease. Testing showed that with the heat dissipation system in place, the module's average power output increased by 2.96% over two days of testing compared to without the system, demonstrating that it successfully reduced the module temperature and improved efficiency as intended.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
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.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
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.
