Chapter 1 : Rate of Reaction
Rate of reaction is defined as the change in quantity of reactants or products per unit time. The average rate is calculated over an interval of time, while the instantaneous rate is the actual rate at a given time. Several factors affect the rate of reaction, including the total surface area and concentration of reactants, temperature, use of catalysts, and pressure for gaseous reactants. According to collision theory, the rate of reaction depends on the frequency and effectiveness of collisions between reactant particles, which must achieve the minimum activation energy and correct orientation.

Epoxy resins were discovered in the 1930s and introduced commercially in the 1940s. They are thermosetting polymers formed by reacting epichlorohydrin with bisphenol A or other core chemicals. Epoxy resins cure via addition polymerization when combined with hardeners, producing crosslinked networks with strong bonds and excellent mechanical and chemical resistance properties. Their applications include coatings, adhesives, composites, and more due to these advantages.
Composite materials
Composite materials are made by combining two or more materials with different properties to create a new material with unique characteristics. The document discusses the history, types, manufacturing, and applications of composite materials. It notes that composite materials are increasingly being used in industries like automotive and aerospace due to advantages like higher strength and stiffness compared to traditional materials, while remaining lightweight. New techniques like textile composites aim to lower costs and improve performance of composites.
Composite materials
Composite materials are engineered materials made from two or more constituent materials with different physical or chemical properties. The materials remain separate within the finished structure. One material, called the reinforcing phase, is embedded in the other material called the matrix phase. Common examples include concrete, where aggregates are embedded in cement, and fiberglass, where glass fibers are embedded in a polymer matrix. Composites are used because their overall properties are superior to their individual components. Some of the oldest composites include wattle and daub and concrete, and composites now make up common materials like asphalt, fiberglass, cement, and plywood.

This study evaluated the use of cationic resin catalysts for the esterification of free fatty acids in macauba palm oil, which has a high acidity of 40.8% that makes it unsuitable for conventional biodiesel production. Esterification experiments using ethanol and methanol as alcohols achieved the greatest acidity reduction of 38.6% using Purolite CT275DR resin at 90°C, 20:1 alcohol:oil ratio, and 8 hours. Temperature had the most significant effect on reducing acidity. The Purolite resin performed better than Mitsubishi PK208 resin due to its higher ion exchange capacity.

Optimization of Sunflower Methyl Ester and its Tribological Studies
The mineral oil lubricants that are being used these days are not sure of lasting for a long time. There are chances of them being depleted in a short span of years. As a replacement for the mineral oils, various vegetable oils are taken up for research purpose in order to use them as an alternate for the present mineral lubrication. Bio lubricant is produced by transesterification of a triglyceride with methanol in the presence of catalyst to produce fatty acid methyl esters (FAME) and glycerol. The main parameters affecting the transesterification reactions are molar ratio, catalyst type and amount, reaction time, temperature and stirrer speed. In this work, the producrion of sunflower methyl ester (SFME) can be optimized by using Taguchi technique and the properties of a lubricant like viscosity, flash point and fire point is found out, also four ball wear test proved that the SFME+crude SFO proportions produced less wear scar than conventional 2T oil which revealed that the prepared bio lubricant can be used in a commercial vehicle.

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

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.

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 coded values of the variables were determined by the following equation. Where xi is the coded value of the ith variable, Xi is the encoded value of the ith test variable and X0 is the encoded value of the ith test variable at center point. The range and levels of individual variables were given in Table 2. The regression analysis was performed to estimate the response function as a second order polynomial. Where Y is the predicted response, βi and βij are coefficients estimated from regression, they represent the linear, quadratic and cubical effect of x1, x2, x3... on response. All results are expressed as mean ± SD for six mice in each group.
