چکیده
In response to the severe floor heave problem of the+1100m track crosscut in Liuyuanzi Coal Mine, it was found that exists a hard top and soft bottom surrounding rock environment. FLAC3D simulation used study stress, plastic zone, displacement when is supported by bolt-mesh+Shotcrete+36U-type steel combined support circular shed support. The results show latter reduces 57%.

Simulation Based Shop Floor Control
This paper presents an overview of simulation-based shop floor control. Much of the work described herein is based on research conducted in the Computer Integrated Manufacturing (CIM) Lab at The Pennsylvania State University, the Texas A&M Computer Aided Manufacturing Lab (TAMCAM), Technion in Israel, and the University of Arizona CIM lab over the past decade. In this approach, a discrete event...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Numerical Solution for Heave of Expansive Soils
A numerical solution for heave prediction is developed within the context theories for both saturated and unsaturated soil behaviors. Basically, lowering the potential level of compressing on a saturated layer will cause heaving due to water absorption. This water absorption is in an opposite way, similar to water dissipation as what happens during unloading in consolidation process. However, i...

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Roadway traffic control software
Roadway traffic control is an important practical example of real time control applications, but effective roadway control is hampered by a variety of organizational, financial and technical considerations. One major hurdle is the current reliance on outmoded field hardware and software. A systematic approach to traffic engineering software development could provide significant advantages with ...
