Abstract Recent years have seen increasing attention being paid towards the problems related to safety and security onboard ships. As a result, International Maritime Organization has issued several new Regulations regarding ships’ systems that must be considered during vessel design phases. In particular, one of most important approaches introduced by this set rules consists Safe Return Port (...

The aim of this study, is to use finite element simulation to achieve the optimal geometry of a broaching tool that creates the lowest tensile stress at the machined surface of the Ti6Al4V alloy. It plays a major role in reducing production costs and improves the surface integrity of the machined parts. The type and amount of residual stress determined by the thermal and mechanical loads transm...

DEVS (Discrete Event System Specification) is widely used in modeling and simulation fields to design, validate, implement complex response systems. provides a robust formalism for system design using event-driven, state-based models with explicitly defined temporal information. We extend the RTL-DEVS model based on enable part of Verilog DEVS-based tools. The methodology, which imitates Verilo...

This paper presents a tool for dynamic simulation of radio resources in WiMAX IEEE802.16e-2005 networks. The developed tool provides an integrated environment for defining user scenario characteristics, BS planning, simulation and analysis. For implementing the different mechanisms of WiMAX radio technology, the simulation tool kernel is defined on a system-level, dynamic, stochastic and a disc...
