IRJET- Study of Ammoniacal Nitrogen Removal from Leachate of Sanitary Lan...IRJET Journal
This document summarizes a study on removing ammoniacal nitrogen from leachate produced at sanitary landfill sites located in hilly terrain in India. The study tested the effectiveness of using brick dust and activated carbon individually and in combination as adsorption materials to remove ammoniacal nitrogen, which is present in high concentrations in landfill leachate. Batch adsorption experiments showed that a mixture of brick dust and activated carbon in a ratio of 1:7 was most effective at removing 40-80% of ammoniacal nitrogen from leachate samples containing around 1000 mg/L of ammoniacal nitrogen. Using this cost-effective combination of locally available brick dust with activated carbon could provide an economically viable option for treating land

Abstract Electrochemical industries generates a wastewater that has a potential hazard for our environment as it contains various heavy metals such as Lead, Cadmium, Nickel etc. If this wastewater left untreated, will pollute soil and water resources. Out of the above heavy metals, in this project work, only removal of Lead (Pb) from electrochemical industrial wastewater has been investigated by using low cost adsorbent such as charcoal along with coconut shell powder as a natural adsorbent. The project is a bench scale experimental type i.e. Batch mode technique and analyses have performed by using different amounts of adsorbent in solutions with different concentrations of Lead metal. Beside the effect of various amounts of adsorbent used in adsorption efficiency experiments has been investigated. Result indicates that the maximum removal efficiency for Lead is about 94% by using 0.25 gm/L amount of activated coconut shell carbon powder (ACSCP) and charcoal powder (ACP) mixed in equal amount for particular pH and contact time.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
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.
