装配式节点质量信息虚体实化及模型构建

为解决装配式建筑节点质量信息分散,难以进行标准化管理的问题,提出虚体实化理念,将各阶段分散的节点质量信息实体化为BIM模型中的图元对象,并随时间属性关联节点质量过程信息,以实现不同阶段的协同管理。基于虚体实化和BIM技术,定义装配式节点质量信息模型(AJQIM),提出质量实体需求、质量实体监控与质量实体检查基本过程信息模型,并阐述其运作流程、核心功能算法与实现路径。基于Revit平台与MySQL数据库,通过C#二次开发,实现AJQIM的建立。研究结果表明,AJQIM对提高装配式节点质量控制的准确性和完整性具有较高的实用价值。

英汉翻译中的虚实互化

虚实互化是英汉翻译中通常采用的变通技巧。所谓虚化实，即把抽象表达法转化为具体表达法，而实化虚即把具体形象的词进行概念化或抽象化处理。

论翻译的“虚实化意”策略

文章从"虚实化意"的视角来探讨文学翻译问题。"虚化"与"实化"是事物的一对矛盾现象,但它们可以互相转化,以适应上下文的要求。如果译者能够正确、灵活地处理这一翻译策略,它将使得译文具有可读性。

Visualization of flatness pattern recognition based on T-S cloud inference network

Flatness pattern recognition is the key of the flatness control. The accuracy of the present flatness pattern recognition is limited and the shape defects cannot be reflected intuitively. In order to improve it, a novel method via T-S cloud inference network optimized by genetic algorithm(GA) is proposed. T-S cloud inference network is constructed with T-S fuzzy neural network and the cloud model. So, the rapid of fuzzy logic and the uncertainty of cloud model for processing data are both taken into account. What's more, GA possesses good parallel design structure and global optimization characteristics. Compared with the simulation recognition results of traditional BP Algorithm, GA is more accurate and effective. Moreover, virtual reality technology is introduced into the field of shape control by Lab VIEW, MATLAB mixed programming. And virtual flatness pattern recognition interface is designed.Therefore, the data of engineering analysis and the actual model are combined with each other, and the shape defects could be seen more lively and intuitively.

Individualization of Head Related Impulse Responses Using Division Analysis

For Virtual Reality(VR) to be truly immersive, it needs convincing sound to match. Due to the diversity of individual's anthropometric measurements, the individualized customization technology is needed to get convincing sound. In this paper, we proposed a simple and effective method for modeling relationships between anthropometric measurements and Head-related Impulse Response(HRIR). Considering the relationship between anthropometric measurements and different HRIR parts is complicated, we divided the HRIRs into small segments and carried out regression analysis between anthropometric measurements and each segment to establish relationship model. The results of objective simulation and subjective test indicate that the model can generate individualize HRIRs from a series of anthropometric measurements. With the individualized HRIRs, we can get more accurate acoustic localization sense than using non-individualized HRIRs.

Application of quaternion in visual simulation of rigid body motion

In recent years,with the extensive applications of high performance computer and the rapid development of the attitude control of the spacecraft,quaternion theory has been widely used.Compared with Euler angles,quaternion not only is simple calculation,but also can avoid the singularity problem of Euler angles,therefore it is widely used in the attitude control of spacecraft.In this paper,Simulink simulation technology is used to establish a rigid attitude simulation model with quaternion method and virtual reality scene by virtual reality modeling language(V RM L)is used to achieve attitude motion visualizationThe simulation results show that the Simulink simulation model can accurately reflect the attitude motion of the rigid body,which is valuable for the research of the attitude control of the spacecraft.

Design and Implementation of a 3D Ocean Virtual Reality and Visualization Engine

In this study,a 3D virtual reality and visualization engine for rendering the ocean,named VV-Ocean,is designed for marine applications.The design goals of VV-Ocean aim at high fidelity simulation of ocean environment,visualization of massive and multidimensional marine data,and imitation of marine lives.VV-Ocean is composed of five modules,i.e.memory management module,resources management module,scene management module,rendering process management module and interaction management module.There are three core functions in VV-Ocean:reconstructing vivid virtual ocean scenes,visualizing real data dynamically in real time,imitating and simulating marine lives intuitively.Based on VV-Ocean,we establish a sea-land integration platform which can reproduce drifting and diffusion processes of oil spilling from sea bottom to surface.Environment factors such as ocean current and wind field have been considered in this simulation.On this platform oil spilling process can be abstracted as movements of abundant oil particles.The result shows that oil particles blend with water well and the platform meets the requirement for real-time and interactive rendering.VV-Ocean can be widely used in ocean applications such as demonstrating marine operations,facilitating maritime communications,developing ocean games,reducing marine hazards,forecasting the weather over oceans,serving marine tourism,and so on.Finally,further technological improvements of VV-Ocean are discussed.

Virtual reality approach for 3D large model browsing on web site

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator’s Garden. Translating building data to the Virtual Reality Modeling Language (VRML) is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-of- detail switching.

Smart Modeling of Maritime Vessels

Currently, the market offers many visualization tools available to graphic designers, engineers, managers and academics working on maritime environments. The practice of visualization involves making and manipulating images that convey novel phenomena and ideas. Visual communication, together with virtual reality environments, is an emerging and rapidly evolving discipline. It brings great advantage over written word or voice alone, as visual sense is by far the most dominant component of human sensory perception. A new smart approach for modeling maritime vessels is described in this paper. Various ways of making modeling relevant for work within the field of maritime management, training and education are discussed.

Research on Simulation and Test of the Nonlinear Responses for the Hydraulic Shock Absorber

Basically on the multi-body system dynamics,the virtual prototype of the hydraulic shock absorber for the bench test is developed in the ADAMS environment.Dynamic behaviors of the absorber are studied by both computer simulation and real test.Numerical predictions of dynamic responses are produced by the established virtual prototype of the absorber and compared with experimental results.It has been shown from the comparison that the vibration behaviors of the prototype with hysteretic damping characteristics are considered to be more identical with the bench test results than those of the same prototype with piecewise linear damping properties are.The current virtual prototype of the shock absorber is correct and can be a developing terrace for the optimizing design of the absorber and matching capability of the whole car.
