Effects of bad drainage on roads
Poor drainage is a major cause of premature road failure. When drainage is inadequate, water can weaken pavement materials in several ways. It reduces the strength of unbound materials in the pavement layers and subgrade. Fluctuating moisture in expansive subgrade soils can cause differential swelling and cracking. Water can also cause mud pumping in flexible pavements and stripping of asphalt. Several case studies from India are described where roads exhibited accelerated deterioration due to issues like blocked drains allowing water to pool on the surface, high water tables causing capillary rise, and flooding from adjacent land or structures overwhelming drainage capacity. Proper drainage is critical for maintaining the bearing capacity and extending the lifespan of roadways.

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%.
Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Case Study of Flyover.pptx
- 1. CASE STUDY OF FLYOVER / BRIDGE AND VARIOUS PROBLEMS AND IT’S SOLUTION
- 2. WHAT IS FLYOVER BRIDGE It is a bridge that carries one road or railway line above another either with or without subsidiary roads, for communication between the two sides. As the traffic on the road goes on increasing and we don’t have any space left in both the dimensions, then the only option left will be to go to the third dimension and that is done through flyover construction.
- 3. TYPES OF FLYOVER BRIDGES ROAD CROSSING RAILWAY CROSSING SIMPLE FLYOVER CLOVERLEAF JUNCTION
- 4. METHODOLOGY OF FLYOVER RAW MATERIAL Acquisition Mining Energy sources Water etc. REALIZATION Production Design Construction UTILIZATION Use Operation Maintenance Repair Life phases of structure Problems Arise In Different Aspect Of Flyover Earth work Surplus excavated earth not leveled and neatly dressed at the disposal place. Less sand filling done under floors. Proper compaction of earth under floors not done. Compaction of earth work in filling not done as stipulated in the contract. Lead chart for disposal of surplus earth not maintained. Excavation of foundation less than specified in drawing.
- 5. COMPONENTS OF A BRIDGE The main parts of a bridge structure are as below: Decking, consisting of slab, girders, trusses, etc… Bearings for the decking. Abutments and piers. Foundations for the abutments and piers.
- 6. SOLUTIONS EXCESSIVE LOADS The solution is to reduce the load or redesign using a bearing with greater capacity. NORMAL FATIGUE FAILURE The remedy is to replace the bearing or consider redesigning to use a bearing having a greater calculated fatigue life. Contamination Clean work areas, tools, fixtures, and hands help reduce contamination failures. Keep grinding operations away from bearing assembly areas and keep bearings in their original packaging until you are ready to install them
