We study rolling radion dynamics of electrified D-brane in NS5-brane background, both in effective field theory and in full open string theory. We construct exact boundary states and, from them, extract conserved Noether currents. We argue that T-duality and Lorentz boost offer an intuitive approach. In the limit of large number of NS5-branes, both boundary wave functions and conserved currents...

Railway yard is the basic composition unit of railways, therefore, the efficiency and quality of railway yard design have a crucial effect on the construction and operation of railways. Plane design is the basis and core of railway yard design, consequently, it is significant to research plane design of railway yard. In this study, through analysis and summary of the research status as well as ...

The concept of the modular multilevel converter (MLC) has been raising interest in research order to improve their performance and applicability. potential an MLC is enormous, with a great focus on medium- high-voltage applications, such as solar photovoltaic wind farms, electrified railway systems, or power distribution systems. This makes it possible overcome limitation semiconductors blockin...

The network of Russian railways provides the movement goods and passengers both within country in context international transport, through which from different countries go transit. In Russia railway lines are double-track fully electrified on main directions EastWest transport corridor. modernization branches Trans-Siberian to state border with China Mongolia continues. paper describes busines...

The article presents the results of research on possibilities developing intermodal rail transport in Visegrad Group countries, Italy and Germany. was conducted based statistical data regarding demand for cargo units transport. Selected elements infrastructure were taken into account as well, i.e. length railway tracks lines (including electrified ones), line density indicator, number terminals...

We have developed an ultrasensitive gas-detection method based on the measurement of a differential capacitance of electrified ionic liquid (IL) electrode interfaces in the presence and absence of adsorbed gas molecules. The observed change of differential capacitance has a local maximum at a certain potential that is unique for each type of gas, and its amplitude is related to the concentratio...

We study the effects of a controlled gas flow on the dynamics of electrified jets in the electrospinning process. The main idea is to model the air drag effects of the gas flow by using a nonlinear Langevin-like approach. The model is employed to investigate the dynamics of electrified polymer jets at different conditions of air drag force, showing that a controlled gas counterflow can lead to ...

We present design, fabrication, and characterization of a small (12 mm × 12 mm × 8 mm) movable railway vehicle for sensor carrying. The miniature railway vehicle (MRV) was mainly composed of a vibrational structure and three legs. A railway was designed and fabricated to power and guide the MRV. It also transmits the sensed data from the MRV to the signal processing unit. The MRV with legs on t...

Railway environments cannot be away from the current evolution of public communication systems. The Long Term Evolution (LTE) mobile communication system is considered to be the natural evolution for current Global System for Mobile Communications Railways (GSM-R). LTE all IP networking technology plays a key role for the integration and convergence of heterogeneous networks and services, both ...
