Confidence Estimates

Simulation-based design and certification is fundamentally about making decisions with uncertainty. However, minimizing uncertainty comes at a price — more testing to better define the variability in input parameters, higher fidelity analyses at a finer scale to limit the uncertainty in the physics, etc. Variability in each input parameter does not affect the uncertainty in the system response equally. Nor does every model refinement reduce the uncertainty in the system response. This paper presents a computational methodology that estimates the sensitivity of uncertainty in input variables and the sensitivity of modeling approximations to the final output. In the current age of large multi-disciplinary virtual simulation, this is useful in determining how to minimize overall uncertainty in analytical predictions. In addition, the methodology can be used to optimize for the best use of computational and testing resources to arrive at most robust predictions.

With the help of the computer simulation technology, the virtual machining simulation system of NC machine tool was built based on the integrated simulation module of the UG NX software. Through setting the NC machine parameter of the virtual machining system, the machining process simulation of the typical parts in virtual environment was completed, which implements the collision and interference checking in the process of NC machining and verifies the correctness of NC programs. Finally, the simulation results prove that the assembly modeling method of virtual simulation system for the NC machining is feasible, and the simulation of machining process can effectively determine the mutual interference problem of the machining system, which lays the foundation for effectively preventing the collision accident.

Speed Up

This paper builds an infrared scene of sphere target based on JAMSE, which provides EO/IR environment and is suite to build infrared imaging simulation system of engineering and engagement-level. In addition, to speed up this infrared imaging simulation, we analyzed the process of external rendering mode, which is applied in JMAES EO/IR environment, and found the external rendering image compounding is a highly independently process, which is suite to parallel computing. After testing on NVIDIA TESLA C2075 GPU with CUDA, and comparing the performance with the corresponding sequentialprocess on CPU, we got a satisfied result. This process obtains a speed up of over 10.

During the COVID-19 confinement, we converted our clinical simulation sessions into simulated video consultations. This study aims to evaluate the effects of virtual simulation-based training on developing and cultivating humanization competencies in undergraduate nursing students. A quasi-experimental study was conducted with 60 undergraduate nursing students. A validated questionnaire was used to evaluate the acquisition of humanization competencies (self-efficacy, sociability, affection, emotional understanding, and optimism). The development of humanization competencies in this group composed of undergraduate nursing students was evaluated using virtual simulation-based training, comparing the levels obtained in these competencies at baseline (pre-test) and after the virtual simulation experience (post-test). After the virtual simulation sessions, students improved their levels in humanization total score and the emotional understanding and self-efficacy competencies, obtaining large effects sizes in all of them (rB = 0.508, rB = 0.713, and rB = 0.505 respectively). This virtual simulation modality enables training in the humanization of care with the collaboration of standardized patients in the form of simulated nursing video consultations and the performance of high-fidelity simulation sessions that comply with the requirements of best practices. Therefore, this methodology could be considered as another choice for virtual simulation. Additionally, this virtual modality could be a way to humanize virtual simulation.

Awj Cutting

This contribution presents the possibilities of applying abrasive water jet (AWJ) technology for multi-material micromanufacture. The working principles of injection and suspension AWJ systems are presented. Characteristics of this technology, such as the ability to machine virtually any kind of material and the absence of a relevant heat-affected zone, are given, especially those from which the production of microcomponents can benefit. A few attempts to miniaturize the AWJ machining process are described in the state-of-the-art preview. In order to develop and improve the AWJ as a microtool, a numerical simulation based on the finite element analysis is introduced to evaluate the effect of the size abrasive particles and the process efficiency of microsized AWJ. An ongoing project in which an improved mini AWJ cutting head is being developed, is presented. Finally, the possible fields of application are given, including a case study on the machining of miniaturized heat sinks.

Underwater interfacing technique is the key technique of the underwater vehicle. Now the technique is mainly used in the submarine rescue. Based on the structural characteristics of the model of BSAV-Ⅰand the interfacing apparatus with the manipulators which are made by Harbin Engineering University, a group of equations were defined and solved based on the six freedom motion of the model. The software Creator and Vega were used to build virtual ocean geographic environment and the deep submergence rescue vehicle(DSRV), the virtual simulation system is created，with which the virtual simulation of the docking process of DSRV and the disable marine is done.
