Infrastructure applications

As a result of preliminary studies, it was concluded that gaps exist between existing piping and pipeline codes and standards, and hydrogen infrastructure applications. A Project Team was formed under the B31 Standards Committee to develop a new B31.12 Code for hydrogen piping and pipelines. The Project Team was subsequently restructured under the B31 Standards Committee as a Section Committee. 

The use of advanced composites has increased significantly in the last decade. The properties of high-specific strength and stiffness make composites ideal for many aerospace, automotive, and infrastructure applications. Fiber-reinforced composites, which commonly use thermosetting resins such as epoxies as the matrix material, have some inherent deficiencies. These include the need for multistep processing, limited shelf-life, low toughness, sensitivity to moisture, and the inability to reprocess or reform the material [1]. 

Strategic and tactical consideration for how the pharmacy software solution matches up with the clinical information systems, Internet solutions, health resource planning, access management, decision support, home care, managed care, and infrastructure applications. 

As composites are proposed in more infrastructure applications, such as bridges, there is an increased demand for long-term data suitable for reliable prediction of lives as long as 120 years. 

A work targeted specifically to civil infrastructure application has reported mechanical data on freeze-thaw tests conducted on isophthalic polyester and vinyl ester pultruded/glass fiber RPs (Chapter 3). Specimens were aged in accordance with ASTM C666 (namely, 40F to OF followed by a hold at OF and a ramp up to 40F followed by a hold) while submerged in 2% sodium chloride and water. Specimens were removed after every 50 cycles and tested in ASTM 3-point flexure mode. The results clearly indicated a reduction in flexure strength and modulus after 300 cycles.

During the last decade, there have been continuous improvements in the selection of constitutive materials, in the manufacturing processes and the field implementation of polymer composites for civil engineering applications. The use of FRP materials as externally bonded reinforcement is now an attractive solution to increase the lifespan of existing concrete infrastructures, while their use as internal reinforcing bars or as structural members is intended to prevent corrosion problems and increase the overall durability of new constructions exposed to severe environments. Nevertheless, key issues regarding the long-term durability of FRPs for infrastructure applications have been only partially addressed, and there remain considerable needs for research and development in this field ... 

In the project, IBM led a team that included up to 33 clients and 27 consultants (including Oracle Consnlting and Delinea as subcontractors) and also worked with an outside infrastructure application service provider. 

Contemporary infrared (IR) systems for the free-space optics (FSO) in the wireless last-mile access, private networks and mobile infrastructure applications mostly utilize the transmission window 0.7-1.55 pm which is very sensitive to some influences of atmosphere. Rain, fog, smoke, dust particles effectively shorten the available range in this window. Typical fog drops have dimensions comparable to the operating wavelengths, and the resulting real-Ufe maximum distances are typically below 200-300 m, although distances of a few kilometers have been achieved in favorable conditions in point-to-point systems [407].
