Location quotient, a volume reading rather than an impact one. It surfaces small, lopsided specialities.

Field profile

Location quotient across every field it publishes in: outside the ring is more than an institution of this size would be expected to publish, inside it is less.

    Which keywords describe research at High Pressure Gas Safety Institute of Japan?

    By fractional works in all years, weighted toward what it does more of than the world: Finite Element Analysis, Fatigue Crack Closure, Fracture Toughness Testing, Microstructure, Mechanical Properties, Numerical Simulation, Loosening Mechanism and Threaded Fasteners.
