Goodness-of-fit tests indicated that the Gumbel Max distribution provided the best fit, followed by Log Pearson III, Generalized Extreme Value, and Gaussian distributions. The analysis found that the Gumbel Max distribution is suitable for predicting expected flood flows in the Meenachil River based on return period.
Data Preparation for Assessing Impact of Climate Change on Groundwater RechargeAM Publications
Climate change is a change in the statistical properties of the climate system when considered over long
periods of time. It significantly affects the various components of hydrological cycle like temperature, precipitation,
evapotranspiration and infiltration. All these components together affect the rate of groundwater recharge. So
understanding the effects of climate change on groundwater recharge is the need of time for the management of
groundwater resources. This paper presents the data preparation initiatives and a suitable methodology that can be
used to characterize the effect of climate change on groundwater recharge. The method is based on the hydrologic
model Visual HELP which can be used to estimate potential groundwater recharge at the regional scale. The success
of Modeling depends on the accuracy of data and the mode of collecting the data. Therefore, identifying the data
needs of a particular modeling study, collection/monitoring of required data and preparation of data set form an
integral part of any groundwater modeling exercise. The main objective of this paper is to describe the exact data
required and its preparation to simulate the groundwater recharge using HELP Model Software for Yavatmal as a
study area situated in Maharashtra state, India. The impact of climate change as a pilot study is modeled by using
computer software HELP (Hydrologic Evaluation of Landfill Performance). The initiatives for data preparation
presented herein may be useful to the researchers in this field.

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.
