This document provides an overview of deep foundations, which transfer structural loads through weak upper soil layers to stronger deeper soils. It describes different types of deep foundations, including piles, caissons, and well foundations. Piles are long slender members that transmit loads through low bearing capacity soils to stronger deeper soils. They can be made of concrete, steel, or composites. Piles are installed using methods like dropping weight hammers, diesel hammers, vibratory insertion, or jacking. The document also discusses pile classification, load transfer mechanisms, precast/prestressed concrete piles, steel H-piles, and large diameter cast-in-place bored piles.
TYPES OF Foundation
This document discusses the functions and types of foundations for building construction. It describes that foundations serve to distribute weight over a large area, prevent unequal settlement, provide a level surface, and stability against sliding and overturning. There are two main types - shallow foundations, which include isolated footings, combined footings, strap footings, grillage footings, and mat/raft footings. Deep foundations include piles, cofferdams, and caissons. Shallow foundations transfer loads directly to the soil or bedrock, while deep foundations transfer loads to deeper, stronger layers using structural elements like piles.

1) Shallow foundations, such as spread footings, are used to transfer structural loads from columns and walls directly to soil. Spread footings spread loads over a large soil area to avoid overstressing the soil.
2) Loads on foundations include dead loads from the structure itself, live loads from occupancy, and other loads like wind forces. Settlements can be uniform or differential, with differential settlement needing to be minimized.
3) Common types of shallow foundations are square, rectangular, circular, continuous strip, combined, and ring spread footings. Foundation depth and location depends on soil properties and surrounding structures.
Foundation and its types and detailed explanation
This document discusses different types of foundations. There are two main types: shallow foundations and deep foundations. Shallow foundations are provided immediately underneath the structure near ground level to distribute loads over a large base area. Deep foundations are constructed well below ground level using methods like piles, wells, or caissons to transfer loads through weaker surface soils to stronger layers below. Pile foundations use long concrete cylinders pushed into the ground to support structures. Well foundations are typically used below water levels for bridges.
Types of pile foundation
1. The document describes different types of pile foundations, including classifications based on function and material.
2. Pile foundations are deep foundations used when shallow foundations are unsuitable due to weak soil. They transfer loads to deeper, stronger soil layers using end bearing, friction, or both.
3. Piles are classified by function as end bearing, friction, compaction, tension, anchor, fender, or sheet piles. Materials used include concrete, steel, timber, composites, and sand. Common pile types are described for each category.

Shallow foundations are foundations that are less than 3 meters below ground level. They include pad, strip, or raft foundations. Shallow foundations transfer structural loads from the building to the soil without overstressing the soil, which could cause excessive settlement or shear failure and damage the structure. Common types of shallow foundations are pad/square spread footings, circular spread footings, continuous spread/strip footings, combined footings, and raft foundations. Shallow foundations are generally used to support structures on soil with adequate bearing capacity and have advantages of lower cost, simpler construction, and use of common materials like concrete. However, they are more susceptible to settlement issues.

This document discusses foundations for buildings. It defines a foundation as the lowest supporting layer that transfers structural loads safely into the ground. Foundations increase stability by taking the structure deep into the ground. They are generally made of materials like brick, stone, or concrete. Foundations are designed based on soil type, site conditions, construction type, and economic factors. Foundations are categorized as either shallow or deep. Shallow foundations include footings that support columns directly on soil, while deep foundations transfer loads through weak soil using piles. Common shallow footing types are isolated, combined, continuous, strap, grillage, and raft foundations.

About foundation and its Types
1. Foundation, Part of a structural system that supports and anchors the superstructure of a building and transmits its loads directly to the earth.
2. To prevent damage from repeated freeze-thaw cycles, the bottom of the foundation must be below the frost line.
3. The foundations of low-rise residential buildings are nearly all supported on spread footings, wide bases (usually of concrete) that support walls or piers and distribute the load over a greater area.
4. A concrete grade beam supported by isolated footings, piers, or piles may be placed at ground level, especially in a building without a basement, to support the exterior wall.

1. Footings are structural members that transmit loads from columns and walls to the soil. The depth and location of foundations depends on factors like soil properties, groundwater, and adjacent structures.
2. Shallow foundations are suitable when surface soils can support loads but not in weak soils. Deep foundations transfer loads to deeper, stronger soils using piles, piers or caissons when near-surface soils are unsuitable.
3. Factors affecting foundation choice include subsurface soil properties, groundwater, structural requirements, construction constraints, codes and regulations, and impact on surrounding structures. Foundation type and depth aim to safely transmit loads without exceeding soil capacity or allowing excessive settlement.
Shallow foundation
Shallow foundations are foundations where the depth is equal to or less than the width. There are four main types of shallow foundations: 1) Spread footings which spread loads over a larger area and are used for light loads or strong soils, 2) Combined footings which are preferred when columns are close together to make construction more economical, 3) Strap or cantilever footings which connect independent footings with a beam that does not transfer pressure to the soil, and 4) Mat or raft foundations which cover the entire area beneath a structure and are used for supporting loads on soft soils by spreading them over a large area.
Chapter 4 deep foundation ( bi )
This document provides an overview of deep foundations and pile foundations. It discusses factors that affect foundation design such as building loads and soil bearing capacity. Deep foundations transfer loads below the ground floor level, usually more than 3m below grade, and include pile foundations. Pile foundations transmit structural loads to deeper subsoil using columns inserted into the ground. Pile types include displacement piles (driven into the ground), replacement piles (bored into place), and composite piles (using multiple materials). The document also describes pile installation methods, classification of piles, advantages and disadvantages of different pile materials, and pile driving techniques.

This document discusses different types of deep foundations, focusing on pile foundations. It describes pile foundations as vertical structural members driven into the ground to transfer structural loads through weak surface soils to stronger deeper soils or bedrock. Piles are classified based on their function as either load bearing, transferring vertical loads through end bearing or friction; or sheet piles, providing lateral soil support. Piles are also classified based on material, including timber, concrete, steel, or composite piles. Driven piles displace soil during installation while bored piles replace soil to form a void that is then filled with concrete. The document provides details on advantages and disadvantages of different pile types.

Foundations grp 1
Raft foundations are large concrete slabs laid on the ground to support buildings. They spread the building load over a wide area, lowering pressure on the soil. This makes raft foundations suitable for unstable soils, areas with soil movement, and buildings with high loads or closely spaced supports. Raft foundations can serve as both the foundation and floor slab. They are used for heavy commercial buildings, in low bearing soils, and where footing overlap would otherwise occur. Advantages include reduced excavation needs and differential settlement.
Types Of Foundation
The document discusses different types of foundations for structures, including shallow and deep foundations. It describes spread footings, mat/raft foundations, piles, piers, and caissons. Spread footings are the most common shallow foundation and involve concrete slabs under columns and load-bearing walls. Mat/raft foundations use a continuous slab to spread loads over a large area, especially for high loads or poor soil. Deep foundations like piles, piers, and caissons extend deeper into the ground to bear loads in stronger soil layers. Piles transfer loads through end bearing or friction, while piers and caissons are constructed by excavating holes and filling with concrete.
Building construction redo
Foundations distribute building loads to the ground and come in two types - shallow and deep. Deep foundations extend through unsuitable soil to reach stronger soil layers below and can be pile or caisson foundations. Pile foundations transfer loads using end-bearing piles or friction piles driven into the ground. Caisson foundations are formed by excavating shafts that are filled with concrete to bear loads. Foundation choice depends on the structure, soil type and depth to suitable bearing layers.
Building construction 3 Steel Joints & Footing
This document provides information on various types of foundations used in construction, including isolated footings, grillage foundations, raft foundations, and rebar (reinforcing steel). Isolated footings are independent footings used to support single columns. Grillage foundations consist of steel beams in tiers to distribute loads over a large area for heavy structures. Raft foundations are concrete slabs that extend across a building footprint to spread loads. Rebar is steel reinforcement embedded in concrete to increase its tensile strength. The document discusses construction details and reinforcement for these foundation types.

Deep foundations such as piles, piers, and caissons are required when surface soil cannot support a structure or when a firm soil layer is too deep to be reached economically by shallow foundations. Piles are slender structural members made of steel, concrete, or wood that are driven or cast in place into the ground. Piles transfer structural loads through skin friction or end bearing. Common pile installation methods include dropping weight hammers, diesel hammers, vibratory hammers, and jacking. Piers are larger diameter cast in place foundations used in dry areas. Caissons are hollow watertight structures sunk into place under bodies of water to form foundations.

The hammers are raised and guided by a hoist mechanism to
ensure proper impact on the pile head.
CONSTRUCTION METHODS OF DRIVEN PILE: VIBRATORY PILE DRIVING
- Vibratory pile driving uses a mechanical vibrator instead of a drop hammer.
- The vibrator is attached to the pile and transmits high frequency, low amplitude
vibrations into the pile and soil.
- This causes the soil particles to rearrange and densify, allowing the pile to
penetrate without application of large impact forces.
- Vibratory driving is suitable for cohesive and loose granular soils.
- It is faster than conventional impact driving but may not be suitable for hard

Traditional construction involves assembling building parts on-site to construct buildings from the ground up. This includes creating foundations, walls, roofs, etc. at the construction site. Common construction methods include concrete, masonry, and wood framing. Foundations transfer loads from the structure to the soil and come in shallow and deep varieties. Different foundation types include pads, raft slabs, piles, which can be made of materials like concrete, steel, or wood. Formwork and scaffolding provide temporary structures to support concrete and crews during construction.
Foundation
This document provides an overview of foundations for building construction. It discusses the importance of foundations in distributing building loads to the ground. There are two main types of foundations - shallow foundations and deep foundations. Shallow foundations include spread footings, grillage foundations, raft foundations, stepped foundations, and mat/slab foundations. Deep foundations transfer loads deep into the earth and include drilled caissons, driven piles, and precast concrete piles. Foundation design considers factors like soil type, structural requirements, construction requirements, site conditions, and cost. The document also discusses waterproofing, drainage, and underpinning foundations.
Pile foundation
This document provides information about a pile foundation project. It discusses what foundations are, types of foundations including shallow and deep foundations, and focuses on pile foundations. It describes where pile foundations are used and how they are classified based on material, load transfer method, and installation type. Specific pile foundation types like timber piles, steel piles, concrete piles, end bearing piles, and friction piles are explained. Pile driving and installation methods like impact hammer, vibration, jetting, precast piles, and continuous flight auger are also summarized. The document concludes with a discussion of pile load tests and their objectives and types.
Introduction to Types of Foundation
This document discusses foundations for structures. It defines a foundation as the low artificially built part of a structure that transmits loads to the ground. Foundations come in two main types: shallow foundations, which are used when soil can support loads within 1.5m of the surface, and deep foundations, which are required when soil cannot support loads near the surface. Shallow foundations include isolated footings, combined footings, raft foundations, and strip footings. Deep foundations include pile foundations, which use long structural members driven or bored into the ground to transfer loads to stronger deeper soils. The document discusses classifications and functions of different foundation types.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all
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%.

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.
