This paper presents an approach for a holistic simulation of forging processes considering the interactions between forging press, tooling system and forging process. It can be used in coupled simulations and will enable industrial users in forging industry to do simulation-aided tool optimizations in the design stage of newly developed forging dies. The final aim is to reduce the time-consumin...

A GNSS/INS deeply-coupled system can improve the satellite signals tracking performance by INS aiding tracking loops under dynamics. However, there was no literature available on the complete modeling of the INS branch in the INS-aided tracking loop, which caused the lack of a theoretical tool to guide the selections of inertial sensors, parameter optimization and quantitative analysis of INS-a...

in this paper, we introduce a hybrid approach based on neural network and optimization teqnique to solve ordinary differential equation. in proposed model we use heyperbolic secont transformation function in hiden layer of neural network part and bfgs teqnique in optimization part. in comparison with existing similar neural networks proposed model provides solutions with high accuracy. numerica...

In this work, we introduce a new design concept: the DC-Coupled Resistive Silicon Detectors, based on LGAD technology. This approach intends to address few known features of first generation AC-Coupled Detectors (RSD). Our simulation exploits fast hybrid combination two packages, Weightfield2 and LTSpice. It demonstrates that key RSD are maintained, yielding excellent timing spatial resolutions...

The optimization model based on minimizing chlorine concentration two water sources after 50 years. order reduce computational complexity, a Kriging surrogate simulation coupled with model. Finally, hypothetical case evaluate accuracy and performance results show ...

Building performance simulation is being increasingly deployed beyond the building design phase to support efficient building operation. Specifically, the predictive feature of the simulation-assisted building systems control strategy provides distinct advantages in view of building systems with high latency and inertia. Such advantages can be exploited only if model predictions can be relied u...

An optimum design of Low-cost housing (LCH) offers low-income urban inhabitants great opportunities to obtain a shelter at affordable price and acceptable indoor thermal conditions. In the present study, the design and operation of a low cost dwelling were numerically optimized using simulation-based approach in which a dynamic building simulation program (EnergyPlus) was coupled with the optim...
