This document summarizes research on optimizing the mechanical properties of bamboo fiber reinforced epoxy composites using response surface methodology. Bamboo fiber mats were mixed with varying amounts of nano-silica and epoxy resin to create composite samples. Mechanical tests evaluated properties like tensile, flexural, and impact strength. Response surface methodology was used to determine the optimal composite composition. A quadratic regression model found the 32H composite, with 3 layers of bamboo fiber and 2% nano-silica, performed best in tensile tests and had high energy absorption. The study concluded a composite with 2 wt.% silica and 2 layers of natural bamboo fiber provided high quality mechanical properties.
Experimental Investigation of Effect of Aluminum Filler Material on Thermal P...
Natural fiber composites are renewable, cheap, completely or partially recyclable, carbon neutral and biodegradable. Their easy availability, lower density, higher specific properties, lower cost, satisfactory mechanical and thermal properties, non-corrosive nature, lesser abrasion to processing equipment, makes them an attractive ecological alternative to glass, carbon or other man-made synthetic fibers. Natural fiber composites are generally very good thermal insulators and thus cannot be used where thermal conduction is desirable. Increase in thermal conduction may be done by adding metal filler powders to the matrix. In this work, the effect of aluminum filler material on thermal properties of chemically treated palmyra fiber reinforced composites is investigated. Thermal properties studied include thermal conductivity, specific heat capacity, thermal diffusivity, thermal degradation and stability. Five different samples with 0%, 25%, 50%, 75%, 100% aluminum powder are considered. With the addition of aluminum filler powder, thermal conductivity increases, specific heat capacity decreases, thermal diffusivity increases and thermal stability improves with maximum at 50% aluminum powder.

The document studies the effect of carbon and ash fillers on the flexural properties of glass fiber reinforced epoxy composites. Composites were fabricated with hand layup using glass fibers, epoxy resin, and either carbon or ash fillers added at 10% by volume. Flexural testing found that composites with carbon filler had slightly higher flexural strength than composites with ash filler, but both fillers improved flexural strength over composites without filler. In conclusion, carbon and ash fillers can significantly increase the flexural strength of glass fiber epoxy composites when added at 10% by volume.

This project presents the study of tensile, flexural & moisture absorption properties of composites made from S-glass, Carbon and E-glass fibre. The specimens are prepared using hand lay-up techniques as per ASTM standard for different thickness 2mm and 3mm and fibre orientation of 30º, 45º and 60º, where an attempt is made to study the properties of composite materials by composing the different materials together to obtain the desired properties by increasing the thickness and fibre orientation. By the variation of thickness tensile strength of hybrid composite is observed for each thickness and is compared with the finite element analysis results. The test ready specimens were subjected to tensile and flexural loads on UTM. This research indicates that tensile strength is mainly dependent on the fiber orientation & thickness of laminated polymer composites. The moisture absorption increases with the fibre, filler content and duration of immersion in water.

Mechanical Characterization of Biodegradable Linen Fiber Composites
Abstract: The conventional materials like iron, mild steel, cast iron etc are having good mechanical properties. Hence they are widely used in structural engineering applications. These conventional materials have some defects like formation of rust, low weight to strength ratio, high production cost. To overcome these defects, engineers started fabricating composite materials. Composites exhibit peculiar properties like different strengths in different directions, rust resistant, high strength to weight ratio, but they pollute the environment. Now the natural fibre composites are widely used in automobile industry. The natural fibres and resins are used to fabricate an eco friendly composite material. Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are
friendly to our health and environment. Bio polymer composites fabricated from natural fibres is currently
the most promising area in polymer sciences. This is designed to assess the possibility of fibre as reinforcing material in composites. Epoxy resin was made a stiffened panel to conduct tensile test. In this paper it is aimed to explain all possible ways to use natural composites in automobile components. The main advantages of using natural fibers are their degradability and light weight. They are environment friendly and also increase the fuel economy

These natural fibers are chosen due to their abundance, low cost, and good mechanical properties. The hand layup method will be used to fabricate the composite.
Mechanical Behaviour of Agricultural Residue Reinforced Composites
The increasing awareness and the quest for newer materials have given renewed interest to the
development of green composites. This article focuses on the potential use of abundantly available waste
agricultural residue for the preparation of composites. The mechanical properties of Rice straw fibers reinforced
with Polyester resin, Vinyl ester resin and Isophthalic polyester resin are studied and compared. Hand Layup
technique is used to prepare the samples on which flexural and impact studies are made. Samples are made using
different volumetric compositions of fiber and resin. The results show that the Vinyl ester resin and Isophthalic
resin offer good mechanical properties when compared to the polyester resin. Both these resins show similar
behavior with respect fiber loading. The flexural strength decreases with increasing fiber loading for polyester
resin and increasing trend is observed for both vinyl ester and isophthalic resin. Impact strength increases for the
increase in fiber loading up to a certain limit and then decreases. It can be concluded from this study that the
agro-waste materials are attractive reinforcements from the standpoint of their mechanical properties.

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.

The document studies the effect of carbon and ash fillers on the flexural properties of glass fiber reinforced epoxy composites. Composites were fabricated with hand layup using glass fibers, epoxy resin, and either carbon or ash fillers added at 10% by volume. Flexural testing found that composites with carbon filler had slightly higher flexural strength than composites with ash filler, but both fillers improved flexural strength over composites without filler. In conclusion, carbon and ash fillers can significantly increase the flexural strength of glass fiber epoxy composites when added at 10% by volume.
Study on Effect of Thickness and Fibre Orientation on a Tensile and Flexural ...
This project presents the study of tensile, flexural & moisture absorption properties of composites made from S-glass, Carbon and E-glass fibre. The specimens are prepared using hand lay-up techniques as per ASTM standard for different thickness 2mm and 3mm and fibre orientation of 30º, 45º and 60º, where an attempt is made to study the properties of composite materials by composing the different materials together to obtain the desired properties by increasing the thickness and fibre orientation. By the variation of thickness tensile strength of hybrid composite is observed for each thickness and is compared with the finite element analysis results. The test ready specimens were subjected to tensile and flexural loads on UTM. This research indicates that tensile strength is mainly dependent on the fiber orientation & thickness of laminated polymer composites. The moisture absorption increases with the fibre, filler content and duration of immersion in water.

Mechanical Characterization of Biodegradable Linen Fiber Composites
Abstract: The conventional materials like iron, mild steel, cast iron etc are having good mechanical properties. Hence they are widely used in structural engineering applications. These conventional materials have some defects like formation of rust, low weight to strength ratio, high production cost. To overcome these defects, engineers started fabricating composite materials. Composites exhibit peculiar properties like different strengths in different directions, rust resistant, high strength to weight ratio, but they pollute the environment. Now the natural fibre composites are widely used in automobile industry. The natural fibres and resins are used to fabricate an eco friendly composite material. Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are
friendly to our health and environment. Bio polymer composites fabricated from natural fibres is currently
the most promising area in polymer sciences. This is designed to assess the possibility of fibre as reinforcing material in composites. Epoxy resin was made a stiffened panel to conduct tensile test. In this paper it is aimed to explain all possible ways to use natural composites in automobile components. The main advantages of using natural fibers are their degradability and light weight. They are environment friendly and also increase the fuel economy

These natural fibers are chosen due to their abundance, low cost, and good mechanical properties. The hand layup method will be used to fabricate the composite.
Mechanical Behaviour of Agricultural Residue Reinforced Composites
The increasing awareness and the quest for newer materials have given renewed interest to the
development of green composites. This article focuses on the potential use of abundantly available waste
agricultural residue for the preparation of composites. The mechanical properties of Rice straw fibers reinforced
with Polyester resin, Vinyl ester resin and Isophthalic polyester resin are studied and compared. Hand Layup
technique is used to prepare the samples on which flexural and impact studies are made. Samples are made using
different volumetric compositions of fiber and resin. The results show that the Vinyl ester resin and Isophthalic
resin offer good mechanical properties when compared to the polyester resin. Both these resins show similar
behavior with respect fiber loading. The flexural strength decreases with increasing fiber loading for polyester
resin and increasing trend is observed for both vinyl ester and isophthalic resin. Impact strength increases for the
increase in fiber loading up to a certain limit and then decreases. It can be concluded from this study that the
agro-waste materials are attractive reinforcements from the standpoint of their mechanical properties.

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.

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

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.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

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.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
