Introduction to prestressed concrete structures
Prestressed concrete combines high-strength concrete and high-strength steel in an active manner by tensioning steel tendons and holding them against the concrete, putting it into compression. This transforms concrete from a brittle to a more elastic material. It allows for optimal use of each material's properties and better behavior under loads. Prestressed concrete was pioneered in the 1930s and its use has expanded, finding applications in bridges and other structures. Common methods are pretensioning and post-tensioning, using various tendon types, with bonded or unbonded configurations. Tensioning is done using mechanical, hydraulic, electrical or chemical devices.

suspension bridge ppt
Suspension bridges have evolved over time through various innovations:
1) Early bridges used ropes and chains that were later replaced by stronger steel cables
2) Advances allowed building foundations underwater and constructing taller towers for longer spans
3) Later bridges had to withstand forces like wind and earthquakes, leading to designs that added stiffness and flexibility
4) Modern construction involves building tower foundations, spinning main cables between anchorages, attaching vertical cables to the deck, and lifting deck sections into place section-by-section.
Canal Irrigation
Canal systems were built centuries ago in Scotland to connect waterways over geographical obstacles. One canal, connecting Falkirk and Edinburgh, had 11 locks to span an elevation difference of 79 feet. In the 1960s, construction began on an innovative solution - a boat lift or water carousel. Completed in 2002, this unique rotating boat transporter saves both time and energy compared to traditional locks. The giant arms can rotate 180 degrees in just 15 minutes, moving boats between the upper and lower canals.
Roller - Compacted Concrete (RCC)
Roller-compacted concrete (RCC) is a concrete that is mixed in a pugmill and placed with dump trucks and spread with bulldozers. It is compacted in lifts of 100-250mm thick using vibratory steel drum rollers. RCC does not require internal vibration and can be used for port, rail, highway, and industrial facilities. Some advantages are reduced cement, no formwork, and ability to maintain traffic flow during placement. Limitations include a rougher surface and difficulty compacting near edges.
self compacting concrete
Self-compacting concrete (SCC) was developed in Japan in the 1980s to solve issues with inadequate concrete compaction. SCC is highly flowable under its own weight and fills formwork without vibration. It was pioneered by Professor Hajime Okamura and has seen increasing use globally since 2000. The document discusses the constituents, properties, testing, and advantages of SCC compared to traditional vibrated concrete.

Suspension Bridges
Suspension bridges can span long distances using cables and vertical suspenders to hang the deck below. They are lightweight yet strong structures using cables anchored at each end and resting on towers. The Golden Gate Bridge is an iconic suspension bridge that connects San Francisco to Marin County, built between 1933-1937. At over 1 mile long, it was the longest in the world until 1964 and demonstrates the advantages of suspension bridges to cross long spans over water.
Bacterial concrete
Bacteria-based self-healing concrete uses dormant calcium-precipitating bacteria encapsulated during mixing. When cracks form and water enters, the bacteria activate, metabolize nutrients, and precipitate calcium carbonate to seal cracks. Testing shows bacterial concrete has higher strength and crack-healing ability compared to normal concrete. While increasing durability, applications in construction could lower costs and improve sustainability over time. Further research is still needed to optimize the technology for practical and economic feasibility at scale.

The document also discusses canal escapes, head regulators, cross regulators, silt control devices, and canal outlets/modules. In particular, it explains the functions and construction of head regulators and cross regulators.
Spillway gates
Spillway crest gates are adjustable gates used to control water flow in reservoir and river systems. They act as barriers to store additional water, allowing the height of dams to be increased and requiring more land acquisition. The main types of spillway gates are dripping shutters, stop logs, radial/tainter gates, drum gates, and vertical lift/rectangle gates. Vertical lift gates are rectangular gates that spin horizontally between grooved piers and can be raised or lowered by a hoisting mechanism to control water flow.
Cofferdams
Cofferdams are temporary structures used to allow construction in areas that would otherwise be underwater or difficult to work in. They are enclosures that hold back water and soil to create a dry work area. Various types of cofferdams exist, including braced, earth-type, timber crib, double-walled sheet pile, and cellular designs. Proper construction and safety precautions are vital as workers will be exposed to flooding hazards. Leakage is prevented through measures like cement grouting, clay sealing, and tarpaulins.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
Keywords
Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.

- 3. What is Gabion ? Gabion is a wirework container (cage, cylinder or box) filled with rock, broken concrete, or other materials, used in the construction of dams, retaining walls, etc. civil engineering structures, road building, and military applications.
- 4. What is Gabion baskets ? Gabion baskets consist of wire mesh containers that are filled with locally available rocks. When stacked together, they can provide some stability to slopes. Common uses includes : Protection from falling rocks or landslides on steep slopes Retaining walls to support terraces Protection of fields, roads and buildings next to flood-prone wadis and waterways
- 5. Advantages of Gabion baskets Porous and free-draining-slowing water movement and reduce soil erosion. Can be made in various sizes. More economical than retaining wall. Easy to assemble on-site and little maintenance required.
- 6. Disadvantages of Gabion baskets When not placed correctly in the landscape, gabion can quickly fail and lead to increase erosion. When use for riverbank stabilization, gabion wall increase water flow rates and can increase erosion to the bank immediately downstream. Gabion wall failure is common in this setting. Some gabion baskets on the markets are faulty and will disintegrate in a matter of months.
- 7. Construction of a Gabion basket wall Construction of gabion basket wall is time consuming and labor intensive. Level and smooth the area for the first row of gabions. Use heavy duty wire mesh to make the gabions. Once assembled, the baskets are filled on site with stones. Layout your first row of empty gabions – this will be the base of the wall. Tie the individual empty gabions together in several spots with heavy duty wire. Fill the gabions with rock. Make sure that the average rock size is larger than the mesh of the gabion, so the rock stays in place. Fill behind the row of filled gabions with soil or rock. Stack new gabions row onto the first row of the wall. Step back the rows to match the slope. Tie each new row to the previous with heavy duty wire.
- 8. Cautions while use of Gabion baskets To control erosion along gully beds, use loose stones check dams rather than gabion baskets. Do not construct gabion baskets walls in flood prone areas unless first consulting an engineer familiar with the areas. Gabion wall failure is common due to frequent misuse in Afghanistan.
