Condensing heat exchangers are important in many space applications for thermal and humidity control systems. The International Space Station uses a cooled fin surface to condense moisture from humid air that is blown over it. The condensate and the air are "slurped" into a system that separates air and water by centrifugal forces. The use of a cooled(More)
We report the first experimental demonstration of a humidity insensitive polymer optical fiber Bragg grating (FBG), as well as the first FBG recorded in a TOPAS polymer optical fiber in the important low loss 850 nm spectral region. For the demonstration we have fabricated FBGs with resonance wavelength around 850 nm and 1550 nm in single-mode(More)
Resilient Packet Ring (RPR) is being devised as part of IEEE 802.17 standard, where fairness in bandwidth allocation among ring nodes, efficiency in resource utilization, and a low computational complexity are the main requirements. Although recent efforts have improved the performance of the RPR fairness algorithms to have acceptable steady-state behavior,(More)
We have systematically measured the differential stress-optic coefficient, DeltaC, in a number of poly(methyl methacrylate) (PMMA) fibers drawn with different stress, ranging from 2 up to 27 MPa. DeltaC was determined in transverse illumination by measuring the dependence of birefringence on additional axial stress applied to the fiber. Our results show(More)
Girardinia heterophylla (Decne), distributed extensively in Middle Himalayas, is a potential source of Leaf Protein Concentrate (LPC). Present study envisages the phytochemical investigations to assess the availability and commercial viability of LPC of G. heterophylla. Samples of plant leaves were collected from Mussoorie Hills of Uttarakhand (India) and(More)
