Reinforced earth structures
Reinforced earth is a combination of earth and linear reinforcing strips that are capable of bearing large tensile stresses.
The reinforcement provided by these strips enable the mass to resist the tension in a way which the earth alone could not. The source of this resistance to tension is the internal friction of soil, because the stresses that are created within the mass are transferred from soil to the reinforcement strips by friction.
Soil stabilisation (1)
This document discusses different methods for soil stabilization, including mechanical, physical, chemical, and bituminous stabilization. Mechanical stabilization involves compacting soil to increase density and strength. Physical stabilization involves blending soils or adding admixtures to improve properties. Chemical stabilization uses lime, cement, or other chemicals like calcium chloride to react with soils and modify their characteristics. Bituminous stabilization involves adding bitumen or asphalt to seal soil pores and increase cohesion between particles. The document provides details on appropriate soil types, required quantities, and construction methods for each stabilization technique.
Types of geosynthetics
This document discusses the different types of geosynthetics, which are human-made materials made from polymers that are used to enhance engineering projects.

Each type is defined and its uses and properties outlined. Geosynthetics provide benefits such as lower costs, quicker installation, consistent performance, and extended lifespan when used in applications like roads, drainage, erosion control, and reinforced soil structures.
Geotextiles
The document discusses geotextiles, which are permeable synthetic textile materials commonly made from polyester or polypropylene polymers. Geotextiles are used in construction applications such as road work, drainage, and coastal protection to increase soil stability, provide erosion control, and aid in drainage. They function by separating soils, filtering water, reinforcing soils, draining water, protecting soils from erosion, relieving stress, and acting as moisture barriers. Common materials used include polypropylene and polyester. Geotextiles are formed through weaving or non-woven processes like needle punching or heat bonding.
Polymer concrete
Polymer concrete is a part of group of concretes that use polymers to supplement or replace cement as a binder.

The document then discusses various types of geosynthetics like geotextiles, geogrids, and geomembranes. It provides examples of using geosynthetics for filtration, drainage, separation, and reinforcement of slopes, retaining walls, and embankments. The advantages include easier installation and higher strength compared to traditional methods.
Ground improvement technique
1) The document discusses ground improvement techniques of preloading and vertical drainage. Preloading involves applying a surcharge load to improve soil strength and reduce settlements before construction.
2) Vertical drains are often used with preloading to accelerate consolidation by shortening the drainage path. Common types are sand drains and prefabricated vertical drains.
3) Vacuum preloading is described as an alternative to conventional preloading using surcharge loads, applying atmospheric pressure via a membrane system instead. This requires an effective drainage and vacuum maintenance system.
Geosynthetic
This document discusses different types of geo-synthetics, which are man-made materials used in geotechnical engineering and construction. It describes eight main categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geocells, geofoam, and geocomposites. Geotextiles are the most commonly used and can be woven or non-woven. Each geo-synthetic has different characteristics and functions, such as separation, reinforcement, filtration, drainage, or containment. Tests are conducted to evaluate geo-synthetics' properties. The conclusion discusses the growth of these materials and their promising future applications.
Use of waste plastic in road construction
1) The document discusses using low density plastic waste in asphalt pavement to help address the growing problem of plastic waste. Plastic waste is shredded and used to coat aggregates, which are then mixed with bitumen to make asphalt.
2) Test results found the plastic-coated aggregate modified asphalt mix showed higher strength than conventional asphalt. Using plastic waste in this way helps reduce the need for bitumen in asphalt mixes.
3) The process and results suggest plastic waste can be effectively utilized in road construction, providing environmental and economic benefits over disposal in landfills.
Polymer concrete
Polymer concrete is produced by mixing mineral fillers with a synthetic or natural resin binding agent. There are three main types: latex-modified concrete, polymer-impregnated concrete, and polymer concrete. Polymer concrete has many benefits including high strength, durability, fire and heat resistance, chemical resistance, and faster cure times. It can develop high compressive strengths within hours or minutes depending on the materials used. Common applications include flooring, containment structures, trench drains, countertops, furniture, and areas with heavy traffic.
Grouting
The presentation illustrates a technique for ground improvement, Grouting. In India, grouting is still not being used very much. In this presentation, I have demonstrated the basic types of grouting, goals of ground improvement and two case studies of grouting.
Polymer concrete
Polymer concrete is a composite material made by impregnating a conventional concrete with monomers like methyl methacrylate or styrene, then polymerizing them to fill its pores and voids. This reduces porosity and improves strength and durability properties. Three main types are polymer impregnated concrete, polymer cement concrete, and polymer concrete. Polymer impregnated concrete uses precast concrete impregnated with monomer then polymerized. It exhibits higher strength, stiffness, and durability compared to conventional concrete.
Pervious Concrete

Jute geotextile
Jute, a natural, eco-friendly biodegradable and annually renewable bast fibre grows abundantly in India and Bangladesh in particular. As reported by Shivani Sridhar, in India, the annual production of jute is of the order of 1.6 million tons with jute sacks being the potent product. Jute industry in India is one of the oldest agro-industries in the world. In India alone about 0.7 million people are dependent on jute production, its manufacture, and marketing for their livelihood (Sridhar 2015:60).
The ingress of man-made polymers poses a threat to the jute industry which is why the diversification of jute products has become an imperative necessity (Sridhar 2015:60). Indian Jute Industries’ Research Association (IJIRA) has developed a number of jute diversified products like Jute Geotextile (JGT) and Jute Agrotextile (JAT) through extensive R & D work utilizing the unique intrinsic properties of jute fibres like high initial tensile strength, low extensibility, high water absorbency, excellent drapability and spinnability (Sridhar 2015:60). Varieties of JGT and JAT namely, woven, non-woven, open mesh woven, pre-fabricated vertical jute drain (PVJD), jute sleeve etc. have been developed by IJIRA with the support of Jute Manufactures Development Council (JMDC). Laboratory study followed by successful field applications has established the efficacy of these products. It is relevant to mention that all geotextiles act as change agents to soil to improve its engineering performance, and its long-term durability is not a technical necessity. Bio-degradability is therefore both a technical and environmental advantage. Man-made geotextiles are questionable from an environmentalist's perspective despite their longer durability. The stress is now on adopting bio-engineering measures to address soil-related problems in civil engineering. The depletion of petroleum reserves and deteriorating environment in the planet should make JGT and JAT more attractive to the end-users. This article indicates the salient properties of JGT and JAT along with references to a few case studies substantiating the efficacy of these two products.

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%.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
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

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.
