Companies which manage railway networks have to cope continually with the problem of operating safety and maintenance intervention issues related to rail surface irregularities. A lot of experience has been gained in recent years in railway applications but the case of tramways is quite different; in this field there are no specific criteria to define any intervention on rail surface restoratio...

The vibration caused by railways is an environmental constraint in the development of over-track buildings. To study influence from high-speed railway on buildings, a finite element model including track, soil, and buildings was set up. Based vertical acceleration sampled rail, equivalent line load acting rails vertically obtained simplified model. On basis verifying simulation measurement resu...

the main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. therefore, railway track desig...

The detection of weapons concealed underneath a person’s cloths is very much important to the improvement of the security of the public as well as the safety of public assets like airports, buildings, and railway stations etc. Manual screening procedure gives unsatisfactory results when the object is not in the range of security personnel and when there is an uncontrolled flow of people. The go...

In the last two decades, a significant number of innovative sensing systems based on optical fiber sensors have been exploited in the engineering community due to their inherent distinctive advantages such as small size, light weight, immunity to electromagnetic interference (EMI) and corrosion, and embedding capability. A lot of optical fiber sensor-based monitoring systems have been developed...

In order to construct survey-grade 3D models of buildings, roads, railway stations, canals and other similar structures, the 3D environment must be fully recorded with accuracy. Following this, accurate measurements of the dimensions can be made on the recorded 3D datasets to enable 3D model extraction without having to return to the site and in significantly reduced times. The model may be com...

Osmanlı İmparatorluğu’nda 19. Yüzyıldan itibaren demiryolu ulaşımına verilen önem artmaya başlamıştır. Bu yüzyıl içerisinde coğrafyasında ticari amaçlar doğrultusunda bir takım imtiyazlarla işletmesi yabancı sermaye kaynaklı yatırımları yapılsa da, Mondros Antlaşması’ndan sonra sadece Anadolu, Rumeli ve Kafkas demiryolunun kısmı kalabilmiştir. Kurtuluş Savaşı’nı takiben Gazi Mustafa Kemal Atatü...
