Nuclear Power02:36

Nuclear Power

Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Area of Science:

  • Ophthalmology
  • Artificial Intelligence
  • Medical Imaging

Background:

  • Cataract is the primary cause of global blindness, with increasing prevalence due to population aging.
  • Delayed cataract treatment can lead to irreversible vision loss, highlighting the need for early detection methods.

Purpose of the Study:

  • To develop and present an Android mobile application for cataract detection using deep learning.
  • To enable early diagnosis and severity grading of nuclear cataracts (NC) using ocular images.

Main Methods:

  • A multi-stage classification approach was employed, analyzing ocular images from the Nuclear Cataract Database.
  • Various convolutional neural network (CNN) architectures (VGG16, ResNet50, VGG11, ResNet18, MobileNetV2, EfficientNet-B0) were evaluated.
  • Models were trained and validated on clinician-labeled images and optimized for mobile deployment.

Main Results:

  • All evaluated CNN models achieved high classification accuracies, ranging from 91% to 94.5%.
  • The mobile application demonstrated real-time analysis capabilities for eye images.
  • Preliminary evaluations confirmed high accuracy in both cataract detection and severity grading.

Conclusions:

  • The developed mobile application shows feasibility for accurate cataract detection and grading.
  • This approach serves as a foundation for future advancements in mobile ophthalmic diagnostic tools.
  • The application offers a significant improvement over existing mobile solutions for eye health assessment.
