The Supreme Court held that telecommunication towers are movable goods because they are manufactured off-site, assembled on-site, can be dismantled without structural damage, and are fixed only for operational stability. The Commissioner of Central Excise, Pune has declared telecom towers as movable property. The issue under consideration was whether towers qualified as “capital goods” and/ or “inputs” for availment of CENVAT Credit by mobile. Movability of telecommunication towers preserves input tax credit eligibility under GST despite exclusion from plant and machinery.
Fiber optic sensor enables in-situ detection of structural strain, enable timely preventive action to reduce structure life cycle cost, improve safety and reliability, and extend operational life cycle. hroughout his career to move the art of metallurgy and steel manufacturing into the realm of science. Many renowned investigators have followed his path and have deservedly been recipients of the Howe Memori l Lecture Award for their efforts in enhancing the science and technology of iron and. This study aimed to develop a spiral deployment scheme of distributed fiber optic sensors (DFOS) and to monitor/assess the post-tensioned force in seven-wire twisted steel cables, based on the pulse-pre-pump Brillouin optical time domain analysis. Each DFOS was placed in a spiral shape between two. Ferdinand et al., Enhancing safety in nuclear power plant with optical fiber sensors, in Proc. Fuel Cycles, Safe Technol, vol. By embedding optical fibers directly into aluminum conductors, engineers gain unprecedented access to real‑time data on strain, temperature, and fault. Fiber optic pressure, strain, linear displacement, and temperature sensor for structural health monitoring.

In this work, we investigate the sensing performance of Fiber Bragg Gratings (FBGs) engineered to operate near EPs through precise structural tuning. This review provides a comprehensive overview of FBG sensor technology. Abstract—Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sen-sitivity to external perturbations, offering new opportunities for precision sensing. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor. Fibre Bragg Grating (FBG) sensors are now a revolutionary technology in the optical sensing area, recognized for their high sensitivity, immunity to electromagnetic interference, and reliability of operation in demanding environments.
This set demonstrates the behavior of light in fiber optics, information transmission, examples of fiber optic sensors, etc. Join Professors Paola from Politecnico di Milano (Italy) and Carlos from Universidad Pública de Navarra (Spain) as they break down the essentials of Fiber Optic Sensors (FOS). It's a device that converts light rays into electronic signals. Think of it like a photoresistor, which changes its resistance based. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. Fiber optic sensor is a new branch in fiber optics in competition with the existing communication system. This version allows audio and one-way PC-to-PC.
