Authors: Agrawal, Ayush Kumar; Kumar, Jayendra
Abstract: A robotic left arm has been developed in this research to assist individuals in safely navigating hazardous environments,
utilizing Internet of Things (IoT) technology to synchronize its movements with those of a human operator in real-time. The
primary objective of this work was to enhance the precision and responsiveness of the arm. Sensors and microcontrollers
(ESP32, Arduino UNO) were integrated into the robotic arm to collect and transmit movement data. Advanced machine
learning algorithms, including Inverse Kinematics, Reinforcement Learning, and Deep Learning, were employed to facilitate
the arm's learning process and improve its actions. The system was evaluated in simulated hazardous scenarios to assess its
performance. The results indicate that the robotic arm can adjust and move accurately, aligning with the human operator's arm
movements. The robotic arm safely manages hazardous materials, demonstrating high precision in executing complex tasks.
These findings underscore the effectiveness and safety enhancement achieved by integrating IoT and intelligent algorithms into
robotic systems for high-risk occupations. This technology significantly enhances emergency response capabilities and critical
operations, delivering dependable and precise robotic assistance. Overall, this research underscores the potential of IoT-enabled
robotic arms to revolutionize human-robot interactions in demanding environments. By showcasing how real-time
synchronization and advanced algorithms enhance the functionality and safety of robotic systems, this research presents a
promising solution for strengthening the operational safety and efficiency in hazardous situations. The development and
utilization of this technology represent substantial progress in fields necessitating precise and dependable robotic assistance,
ultimately promoting improved collaboration between humans and robots in high-risk contexts.

Authors: Chawla, Sumit; Singari, Ranganath M
Abstract: Before constructing the actual production plant architecture, the simulation builds a virtual production model that is
identical to the real environment and offers insights into the future. By using simulation, we can test the behaviour of the
expensive and sophisticated manufacturing system without physically putting any money in it. In this study, Flexsim is used
for the first time to model and simulate the production of two-wheeler crankcase covers. In this work, a simulation model for
crankcase cover production processes in the automotive sector is developed. Flexsim simulation tool is used as an
optimization tool for analysing the bottleneck or performing the line balancing. The results indicate that by eliminating the
bottleneck in the production line, it increases the line efficiency as well as the production throughput. Initially production
line efficiency is just 51.8% when bottleneck is present. After bottleneck is removed, it increases not only throughput but
also line efficiency to 97.29%. All manufacturing sectors will profit from these findings.

Authors: Ghardallou, Wafa; Abaalkhail, Layla
Abstract: The existing literature does not present a unified perspective on the impact of financial development on environmental
quality. Consequently, this study seeks to enhance existing knowledge by investigating how institutions moderate the
relationship between financial development and carbon emissions. It uses a dynamic GMM model to estimate a panel data
of GCC countries over the period 2010–2020. Financial system development has been proxied by both the development of
the banking sector and the development of the financial markets. The findings indicate that there is a significant increase in
carbon dioxide emissions as a result of financial development. Nevertheless, the presence of strong institutions mitigates this
effect, leading to a reduction in carbon emissions. Indeed, findings reveal that control of corruption, good quality of
regulations and a strong rule of law contribute to reduce pollution effects of financial development. In light of this,
policymakers should focus on enhancing institutional quality while redirecting their focus towards environmentally
responsible financial practices. This approach will bolster the impact of financial development in effectively improving
environmental quality.

Akramhttp://nopr.niscpr.res.in/handle/123456789/644062024-08-12T10:22:40Z2024-08-01T00:00:00ZTitle: Exploring Petcoke Fly Ash Characteristics for Wider Application as Cement-Based Composites
Authors: Parmar, Varsha; Padmakaran, Prabha; Khan, Mohd. Akram
Abstract: As country’s demand for petroleum coke in power plants is increasing drastically as a substitute for coal due to its high
carbon content and easy availability, it results in large generation of petcoke combustion byproducts. Reducing the potential
leachability of possible heavy metals from these byproducts is a crucial issue for its safe disposal and proper utilization. In
this study, Petcoke Fly Ash (PCFA) and Bed Ash (BA) were characterized for mineralogical, morphological, metal analysis
using analytical technique like XRD, SEM, HR-TEM, WD-XRF, FTIR, AAS and leachability studies using TCLP. Results
showed mean particle size of PCFA is 18.015 μm and BA is 41.165 μm, leachable concentration of Vanadium, Nickel,
Chromium, Manganese, Aluminium, Barium and other heavy metals in both ashes, XRD shows presence of CaSO4, V2O5
and CaO, SEM and HR-TEM micrographs confirm that PCFA and BA have porous morphology with varying size and
irregular particles with interplanar spacing of 0.35 nm and 0.32 nm respectively. Results also confirmed the resemblance of
PCFA with PPC in terms of fineness (PCFA=2960 m2/g and PPC≥3000 m2/g, consistency (PCFA 36–45% and PPC
25–35%). The study concluded that based on textural, compositional and mechanical properties, PCFA and BA have potential
as an alternative raw material in cement concrete for application in development of low cost, green construction materials.
