1. Anji Khad bridge

  • The Anji Khad bridge is an under-construction cable-stayed bridge over the Anji Khad river connecting Katra and Reasi Section of Jammu–Baramulla line. 
  • It is India’s first cable-stayed railway bridge. 
  • It is supported by a single pylon — a large vertical tower-like structure — soaring 1,086 feet from the river bed, the height of a 77-storey building. 
  • The bridge will pave the way for a single broad-gauge track for trains connecting Jammu to Baramulla, via Srinagar, along a 326-km railway line.
  • The project was commissioned by the Northern Railways and is being executed by Konkan Railway Corporation Ltd. (KRCL) and Hindustan Construction Company.
  • The idea was first conceived in 2002 during Atal Bihari Vajpayee’s tenure as Prime Minister, and was declared a “national project”.
  • The nearest border area is Suchetgarh, about 92 km from the bridge construction site.

2. Origin of Nuclear Fuel

  • Scientists in China have developed a technique to reliably identify whether some nuclear fuel originated in one of two common kinds of nuclear reactors using experimental data and machine-learning (ML).
  • The reactor type, the fuel’s exposure time inside the reactor, and the extent of the fuel’s enrichment can uniquely identify spent nuclear fuel.
  • Nuclear fuel is a highly regulated material because of its destructive potential. Countries maintain detailed inventories to safeguard it.
  • Identifying the origin of nuclear fuel is a difficult task in nuclear forensics.
  • Nuclear forensics uses analytical methods to identify the origins of nuclear materials and whether they were used for military applications.
  • Spent fuel from boiling water reactors (BWRs) is hard to differentiate from that from pressurised water reactors (PWRs) because both “use water as moderator and have similar thermal neutron spectra, so they are quite similar in neutron reaction mechanism.
    • Therefore, scientists from China have trained data from the database to develop three ML models to distinguish fuel from BWRs from that from PWRs.
  • In BWRs, the fuel rods are submerged in water. When the fuel fissions, the water boils and the steam drives a turbine. In PWRs, the fuel rods aren’t exposed to the water; only the heat is exchanged.

Q2. Which of the following are the Applications of Artificial Intelligence?(Level-Easy)
  1. AI can help reduce the possibility of credit card fraud
  2. AI helps individuals and businesses from Email spam.
  3. AI applications are used in healthcare to build sophisticated machines that can detect diseases and identify cancer cells
  4. Artificial Intelligence is used to identify defects and nutrient deficiencies in the soil.
  5. AI assists in detecting data overflow in a buffer.

Options:

  1. 1 and 2 only
  2. 1, 2, 4 and 5 only
  3. 3, 4 and 5 only
  4. 1, 2, 3,4 and 5
CHECK ANSWERS:-

Answer: d

Explanation:

  • Statement 01 is correct, AI can help reduce the possibility of credit card fraud. AI is able to analyse huge numbers of transactions in order to uncover fraud patterns, and eventually use them to detect fraud in real-time and even prevent it.
  • Statement 02 is correct, Machine learning informs AI when it scans incoming emails. It looks for emails that signal red flags and filter out spam emails.
  • Statement 03 is correct, Artificial intelligence can assist providers in a variety of patient care and intelligent health systems. Artificial intelligence techniques ranging from machine learning to deep learning are prevalent in healthcare for disease diagnosis, drug discovery, and patient risk identification.
  • Statement 04 is correct, The AI deep learning application aids the growth of flora pattern analysis in agriculture. The AI-driven software tools support our understanding of soil imperfections, plant pests, and diseases. Farmers use AI to control weeds using computer vision, robotics, and Machine learning.
  • Statement 05 is correct, AI can be used to detect vulnerabilities in software, detecting data overflow in a buffer.
