This paper explores the development of rail systems in Ireland and Australia. The paper highlights the different trajectories of both systems and charts the experiences and influences of Empire and Commonwealth on both. In Australia the rail system was developed as a way to promote nation building and overcome isolation while in Ireland both prior to and after partition the system enabled acces...

Genetic diversity of the wild population of the endangered Okinawa Rail, Gallirallus okinawae, was revealed by analyzing haplotypes in the mitochondrial control region for 177 individuals. We found 6 haplotypes with nucleotide differences at 6 sites. The four major haplotypes, Type 1 to Type 4, were present in 121 (68.4%), 21 (11.9%), 8 (4.5%) and 25 individuals (14.1%), respectively. Type 5 an...

Abstract. This paper shows a solution to measure the curvature of a rail-guide in which a robot manipulator moves. Such robot, denominated Roboturb, is destined to welding tasks in rotors of high power hydraulic turbines damaged by cavitation effect. This robot has as mainly characteristics the fact of presenting small load (total mass of 20kg), high mobility level due to its seven degrees of f...

Accession of the Republic of Poland to the European Union (EU) has committed Poland to adopt, among others, policy of opening up the market of products and services in the area of rail transport. Follow decision about the opening of the EU market and transport services for rail transport, the European Parliament and of the Council have introduced a number of safety and interoperability directiv...

The problem of damping the noise on track, arising from movement train, is solved sufficiently but it simple, if rail with spacers laid inside longitudinally located band sleeper-mechanism. result a layered thread, consisting belts: tape elastic three sides, tie-mechanism and ballast layer. unity layers carried out due to their own mass. This static track without external load. Rail compression...

The principal causes of cracking in prestressed concrete sleepers are the dynamic loads induced by track irregularities and imperfections in the wheel-rail contact and the in-phase and out-of-phase track resonances. The most affected points are the mid-span and rail-seat sections of the sleepers. Central and rail-seat crack detection require visual inspections, as legislation establishes, and i...

This paper describes a fully diierential dual-ended ultra low-voltage (ULV) FGUVMOS operational transconductance ampliier (FGUVMOS-OTA). The OTA has no internal nodes, rail-to-rail operation, and a dynamic load.
