Compared with safety assessment, security risk assessment in chemical and process plants is more challenging. On top of uncertain environmental operational parameters interdependent failures, which are common the complex systems infrastructures, there other such as likelihood attack scenarios attackers' expected outcomes. As such, application probabilistic (PRA) techniques, have long been appli...

Many companies struggle to find the right balance between reducing costs and growing their business. It seems like an impossible equation for some, while others it is a great challenge. The main purpose of business make profit, that is, get money as result investment work done. One means increasing productivity improvements based on new ideas. Companies tend overlook one very important aspect d...

in this paper, vacuum assisted resin transfer molding (vartm) method was simulated by analytical solution. then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...
