Multifunctional Complex of Thermomechanical Calibration by Screw Compression

Multifunctional Screw Compressor Rotors

For many years the authors have been investigating the use of twin screw machines to fulfil both the expansion and compression. One of potential advantages of screw machines over other types of positive displacement machine is their ability to perform both the compression and expansion functions simultaneously, using only one pair of rotors. A further feature is the use of the rotors which seal...

Multifunctional Crosslinking Agents on the Thermomechanical Properties of Polyimide Films

Three new polyfunctional amines were synthesized. Polyimide films containing varying amounts of the amine crosslinking agents were prepared. Their thermomechanical properties were compared with those of control film samples prepared from difunctional amines. The effect of crosslink density on isothermal weight loss, polymer softening, and glass transition temperature is discussed. EFFECTS OF MU...

Stratified Self Calibration from Screw-Transform Manifolds

Metric Self Calibration from Screw-Transform Manifolds

Abstract This paper introduces a method for metric selfcalibration that is based on a novel decomposition of the fundamental matrix between two views taken by a camera with fixed internal parameters. The method blends important advantages of the Kruppa constraints and the modulus constraint: it works directly from fundamental matrices and uses a reduced-parameter representation for stability. G...
