With the high speed railway speed increasing and driving distance shortening in China, the time conformity of subsystems of railway is becoming more significant to railway traffic safety. The railway time synchronization network (RTSN), the medium carrying and broadcasting time information, is responsible to convey the information of internal clock of railway and its function poses direct influ...

A major problem addressed in railway network planning relates to distinguishing the role of the railway line in the network, and making a reasonable classification of the lines based on their role. Accessibility has been widely used to measure the role of transportation infrastructure in various studies, but few quantitative models for the classification of the role have been presented yet. In ...

‎We study dual integral equations which appear in formulation of the‎ ‎potential distribution of an electrified plate with mixed boundary‎ ‎conditions‎. ‎These equations will be converted to a system of‎ ‎singular integral equations with Cauchy type kernels‎. ‎Using‎ ‎Chebyshev polynomials‎, ‎we propose a method to approximate the‎ ‎solution of Cauchy type singular integral equation which will ...

With increasing capabilities of electric motors and energy storage, aircraft designs for electrified commuter regional become more relevant than ever. Design concepts are often derived optimised according to existing, conventional reference aircraft; however, their characteristics differ the underlying trade-offs divergent. This work aims derive describe major external requirements design propo...

Harmonic generation in power system networks presents significant issues that arise utilities. This paper describes a machine learning technique was used to conduct research study on the harmonic analysis of railway stations. The an investigation time series whose values represented total distortion (THD) for electric current. based information collected at station. In electrified substation, m...

The epidemics of obesity and diabetes most apparent in recent years had their origins with Thomas Edison's development of distributed electricity in New York City in 1882. His original direct current (DC) generators suffered serious commutator brush arcing which is a major source of high-frequency voltage transients (dirty electricity). From the onset of the electrical grid, electrified populat...

When dielectric materials are brought into contact and then separated, they develop static electricity. For centuries, it has been assumed that such contact charging derives from the spatially homogeneous material properties (along the material's surface) and that within a given pair of materials, one charges uniformly positively and the other negatively. We demonstrate that this picture of con...

Railway suicide is a significant public health problem. In addition to the loss of lives, these suicides occur in public space, causing traumatization among train drivers and passengers, and significant public transport delays. Prevention efforts depend upon accurate knowledge of clustering phenomena across the railway network, and spatial risk factors. Factors such as proximity to psychiatric ...

Making great strides in social economy, demands for the material is growing, at the same time,it also stimulates the development of logistics.The railway-water combined transportation of our country is being into a golden opportunity, With the support of national policy and the improvement of railway transportation capacity,it's preparing for the development conditions of the railway-water comb...

The economy of China and the travel needs of its citizens depend significantly on the continuous and reliable services provided by its railway system. However, this system is subject to frequent natural hazards, such as floods, earthquakes, and debris flow. A mechanism to assess the railway system vulnerability under these hazards and the design of effective vulnerability mitigation strategies ...
