3D Digital Design of Cranes' Structures Based on Hybrid Software Architecture

3D digital design for cranes’ structures based on hybrid software architecture of Client/Server and Browser/Server is introduced in this paper. Based on Pro/ENGINEER platform,3D parametric model family is built to allow generation of feasible configurations of cranes’ structures in Client/Server framework. Taking use of Visual C++,the second exploiting software kit provided by Pro/ENGINEER and ANSYS GUI/APDL modeling patterns,an integration method of 3D CAD and CAE is achieved,which includes regeneration of 3D parametric model,synchronous updating and analysis of FEA model. As in Browser/Server framework,the 3D CAD models of parts,components and the whole structure could also be displayed in the customer’s browser in VRML format.

Analysis and design for architecture-based software

The technologies of software architecture are introduced, and the software analysis-and-design process is divided into requirement analysis, software architecture design and system design. Using these technologies, a model of architecture-centric software analysis and design process（ACSADP） is proposed. Meanwhile, with regard to the completeness, consistency and correctness between the software requirements and design results, the theories of function and process control are applied to ACSADP. Finally, a model of integrated development environnment （IDE） for ACSADP is propcsed. It can be demonstrated by the practice that the model of ACSADP can aid developer to manage software process effectively and improve the quality of software analysis and design.

Software Architectural Design in Agile Environments

In this paper, we propose a novel methodology to guide and assist practitioners supporting software architecture and design activities in agile environments. Software architecture and design is the skeleton of a system. It defines how the system has to behave in terms of different functional and non-functional requirements. Currently, a clear specification of software architectural design activities and processes in agile environments does not exist. Our methodology describes in detail the phases in the agile software design process and proposes techniques and tools to implement these phases.

Software Composition Using Behavioral Models of Design Patterns

Given a set of requirements structured as design problems, we can apply design patterns to solve each problem individually. Much of the published literature on design patterns addresses this problem—pattern association;however, there is no systematic and practical way that shows how to integrate those individual solutions together. We propose a compositional model based on design patterns by abstracting their behavioral model using role modeling constructs. This approach describes how to transform a design pattern into a role model that can be used to assemble a software application. The role model captures the behavioral relationship between participant components in the design pattern. Our approach offers a complete practical design and implementation strategies, adapted from DCI (Data, Context, and Interaction) architecture. We demonstrate our technique by presenting a simple case study complete with design and implementation code. We also present a simple to follow process that provides guidelines of what to do and how to do it.

Software Frameworks, Architectural and Design Patterns

Software systems can be among the most complex constructions in engineering disciplines and can span into years of development. Most software systems though implement in part what has already been built and tend to follow known or nearly known architectures. Although most software systems are not of the size of say Microsoft Windows 8, complexity of software development can be quick to increase. Thus among these methods that are the most important is the use of architectural and design patterns and software frameworks. Patterns provide known solutions to re-occurring problems that developers are facing. By using well-known patterns reusable components can be built in frameworks.Software frameworks provide developers with powerful tools to develop more flexible and less error-prone applications in a more effective way. Software frameworks often help expedite the development process by providing necessary functionality “out of the box”.?Providing frameworks for reusability and separation of concerns is key to software development today. In this study I take a look at the state of art and the impact of frameworks and patterns in software development.

Integrated Building Envelope Design Process Combining Parametric Modelling and Multi-Objective Optimization

As an important element in sustainable building design, the building envelope has been witnessing a constant shift in the design approach. Integrating multi-objective optimization (MOO) into the building envelope design process is very promising, but not easy to realize in an actual project due to several factors, including the complexity of optimization model construction, lack of a dynamic-visualization capacity in the simulation tools and consideration of how to match the optimization with the actual design process. To overcome these difficulties, this study constructed an integrated building envelope design process (IBEDP) based on parametric modelling, which was implemented using Grasshopper platform and interfaces to control the simulation software and optimization algorithm. A railway station was selected as a case study for applying the proposed IBEDP, which also utilized a grid-based variable design approach to achieve flexible optimum fenestrations. To facilitate the stepwise design process, a novel strategy was proposed with a two-step optimization, which optimized various categories of variables separately. Compared with a one-step optimization, though the proposed strategy performed poorly in the diversity of solutions, the quantitative assessment of the qualities of Pareto-optimum solution sets illustrates that it is superior. © 2016, Tianjin University and Springer-Verlag Berlin Heidelberg.

Exploration of nature-based biomimetic approach in landscape architectural design: parametric study of candelabra model design

This research provides an exploration of a biomimetic approach in the process of designing a candelabra model using linear shaped leaves of a Bell flower.The design process described in this research contains two steps:biological and geometrical.In the first biological step,a proper model for the creation of an urban element was found from nature in a Bell flower(Campanula persicifolia L.).The upper leaves of the selected plant,which are small with a linear spear and sharpening at the top,were chosen for the modeling process.The second step included applying two geometrical methods,i.e.,Voronoi diagrams and Delaunay triangulation.A geometrical leaf form of the selected plant species and the modeling process were obtained using aparametric modeling software,Blender.Using different Blender plug-ins and modifiers,Delaunay triangulation and Voronoi diagram were implemented by marking the starting points on the leaf form in the image data source,adjusting the Delaunay triangulation parameters,and creating Voronoi diagrams in which the Voronoi points were located at the shortest distance from the edges of the Voronoi polygon.Consequently,a three dimensional model of a candelabra was developed through this study.
