Abstract. Cutting tool resistance to abrasion are among the most important factors in the efficiency of earth pressure balance (EPB)–tunnel boring machines (TBMs). Excessive wear negatively affects the operating parameters of the tunneling machine and reduces its efficiency. Considering the lack of a comprehensive and accepted method …

Abstract: We have investigated the performance of the mono-layer MoS 2 tunnel FET (TFET) through quantum transport simulations based on density functional theory (DFT). Two kinds of source/drain metal contact configurations namely the seamless contact and side contact are compared. It was found that ideal band bending control by seamless …
Mining & Tunneling Simulator. Blast rocks, drill tunnels and force your way through every mountain. At the beginning you have enough time and no major problems. Once the TNT charges are placed you can start the blasting to create the tunnel entrance. The excavated material will be loaded by a shovel dozer on a dump truck and transported to the ...
Abstract: We propose a new compact MTJ model for circuit simulation which is implemented by Verilog-A and can be easily built in de-facto standard SPICE. The model is based on switching probability of an MTJ with time-varying input current. The transition between the adiabatic precessional model and the thermal activation model is made …

The simulator enables the investigation of the effects of atomic defects and trapped charges on the performance of the atomically thin HT transistor. It is shown that the ultra-steep SS in TMD vertical tunneling FETs is robust against both atomic defects in the TMD layers and charged impurity scattering. ...
Нэг ёсондоо алтны олборлолт нэмэгдсэн гэсэн үг. Үүнийг дагаад алтны компаниуд олширсон байх? - Хамгийн эрчимтэй олборлоод мөнгө болдог зүйл бол алт шүү дээ.
Shield tunneling under complex geological conditions may lead to uneven surface settlement, thereby posing risks of damaging adjacent structures. This paper introduces the Geological Model for Numerical Simulation (GFNS) software, which employs OpenGL to implement a 3D geological model. The software incorporates an advanced geological …

You have to steer all vehicles like the maintenance van, crane, tunnel drilling machine or the fire brigade. That's how you'll create the building site piece by piece before starting the tunnel itself. You'll need to pay attention to many factors. The tunnel drilling machine has to be kept supplied with building materials.
