4. wbm roads 10 sep
WBM roads are low-cost roads made of crushed stone aggregates that are mechanically interlocked and bound with water. The aggregates are spread and rolled to form the wearing surface. WBM roads can be used as a base course for bituminous or concrete roads. They have a thickness ranging from 8-30 cm and a camber of 2.5-3%. Construction involves preparing the subgrade, laying the base course and intermediate layers, and forming the wearing surface. Rolling is used to compact the layers and requires sprinkling water while rolling over 80 passes.

Gravel Roads - The Economic Backbone of the State
Gravel roads are an economic backbone in North Dakota, making up over 97,000 miles or 59% of the state's road network. Proper gravel specifications and testing are key to ensuring durability and reducing long-term maintenance costs.

Transportation Pavement.pptx
This document provides information on different types of pavements, including flexible and rigid pavements. It describes the key components and layers of a flexible pavement, such as the surface course, binder course, base course, and subgrade. Rigid pavements are made of concrete slabs and can be jointed plain, jointed reinforced, continuous reinforced, or prestressed concrete. Composite pavements combine aspects of flexible and rigid pavements for benefits such as a strong concrete base with a smooth asphalt surface.
Low Cost Road Methods and Units with detailed elabroration
Low cost roads are constructed in rural and mountainous areas using locally available material and labor to reduce expenses. There are four main types: earth roads made of local soil; kankar roads using limestone chips; water bound macadam roads with crushed stone compacted with water; and gravel roads. Earth roads are the simplest and cheapest to build but require more maintenance, while water bound macadam can support more traffic and last longer if properly maintained. The key aims of low cost roads are to provide basic access where conventional roads would be too expensive, using optimized designs, materials and construction methods.

Components of Railway Track Formation
Usual forms of cross-sections:
The naturally occurring soil is known as the subgrade and when it is prepared to receive the ballast and track, it is called the formation.
When the formation is raised on bank of earth, it is called an embankment.
When embankment is made after cutting the ground below ground level, it is called in cutting

hochPPT thesis statement master civil engineering.pptx
The document summarizes an internship project involving the extension of an SGTD pool yard at the Doraleh container terminal in Djibouti.
The project involved designing access roads and describing the entire project. For the access roads, dynamic compaction and stone columns were used to strengthen weak soils. Pavement designs were calculated using AASHTO methods.
The pool yard extension involved backfilling in phases and installing stone columns using vibro-replacement methods to prevent liquefaction. PLAXIS 2D modeling was used to analyze settlements. Heavy duty pavers were laid over cement-bound granular material and sand beds.

Recycled Concrete Aggregate in Construction Part III
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
A SYSTEMATIC RISK ASSESSMENT APPROACH FOR SECURING THE SMART IRRIGATION SYSTEMS
The smart irrigation system represents an innovative approach to optimize water usage in agricultural and landscaping practices. The integration of cutting-edge technologies, including sensors, actuators, and data analysis, empowers this system to provide accurate monitoring and control of irrigation processes by leveraging real-time environmental conditions. The main objective of a smart irrigation system is to optimize water efficiency, minimize expenses, and foster the adoption of sustainable water management methods. This paper conducts a systematic risk assessment by exploring the key components/assets and their functionalities in the smart irrigation system. The crucial role of sensors in gathering data on soil moisture, weather patterns, and plant well-being is emphasized in this system. These sensors enable intelligent decision-making in irrigation scheduling and water distribution, leading to enhanced water efficiency and sustainable water management practices. Actuators enable automated control of irrigation devices, ensuring precise and targeted water delivery to plants. Additionally, the paper addresses the potential threat and vulnerabilities associated with smart irrigation systems. It discusses limitations of the system, such as power constraints and computational capabilities, and calculates the potential security risks. The paper suggests possible risk treatment methods for effective secure system operation. In conclusion, the paper emphasizes the significant benefits of implementing smart irrigation systems, including improved water conservation, increased crop yield, and reduced environmental impact. Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.
Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

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%.
