The Times Higher Education?World University Rankings 2015-2016?engineering and technology subject ranking?includes a wide range of narrower subject areas.

The full list of engineering and technology subjects used to create this ranking is:

• Acoustics
• Aerospace Engineering
• Automation & Control Systems
• Biomedical Engineering
• Chemical Engineering
• Civil Engineering
• Computer & Information Science
• Construction & Building Technology
• Earth & Environmental Engineering
• Electrical & Electronic Engineering
• Energy & Fuels
• Imaging Science & Photographic Technology
• Industrial Engineering
• Instruments & Instrumentation
• Marine Engineering
• Materials Science
• Mechanical Engineering
• Mechanics
• Metallurgy & Metallurgical Engineering
• Mining & Mineral Processing
• Nuclear Science & Technology
• Operations Research & Management Science
• Robotics
• Telecommunications
• Transportation
• Engineering & Technology - Other topics

The subject tables employ the same range of?13 performance indicators?used in the overall World University Rankings, brought together with scores provided under five categories.

However, the overall methodology is carefully recalibrated for each subject, with the weightings changed to suit the individual fields.

The weightings for the Engineering and Technology ranking are:

• Teaching:?the learning environment
  30 per cent
• Research:?volume, income and reputation
  30 per cent
• Citations:?research influence
  27.5 per cent
• International outlook:?staff, students and research
  7.5 per cent
• Industry income:?innovation
  5 per cent

No institution can be included in the overall World University Rankings unless it?has published a minimum of 200 research papers a year over the five years we examine.

But for the six subject tables, the threshold drops to 100 papers a year for subjects that generate a high volume of publications and 50 a year in subjects such as social sciences where the volume tends to be lower. Although we apply some editorial discretion, we generally expect an institution to have at least 10?per cent of its staff working in the relevant discipline in order to include it in the subject table.

In rare cases where such data are not supplied, institutions are either excluded or public sources are used to underpin estimates.
