A visual approach to simulation of icon‐based Chinese input method

Journal of the Chinese Institute of Engineers 1989年第3期12卷 361-372页

This paper presents a visual programming environment for users to develop their own defined icon‐based Chinese input methods. It will show the following four aspects. First, Chinese characters are concrete icons (decomposition graphs or webs). Second, a grammar that generates the above mentioned webs is a context‐free web grammar. Third, an icon‐based Chinese input method defines semantic rules to the production rules of the web grammar which then becomes an attributed web grammar. Fourth, a Chinese input simulator is a machine that accepts these webs. Developing such a simulator can be regarded as the construction of a user‐defined application program under the proposed visual programming environment. This paper also shows that form‐based visual languages included in the environment can be used to specify ways of evaluation and simulation in the user‐defined simulator.

The primary objective of this research is to demonstrate the feasibility of a model-based construction safety assessment system using building information modeling (BIM) and diagnosing accident-prone BIM objects through prevention through design (PtD). Although extensive research has focused on early risk detection and accident predictions in safety, previous approaches have often missed opportunities to identify safety issues arising from design choices. Potential safety risks have been assessed retrospectively by reconstructing safety concerns based on completed design options. To address this gap, this research aims to provide foresight regarding construction safety hazards from the early design stage. First, risks embedded in design decisions are identified by analyzing safety incident reports using text-mining techniques. Then, the relationships among design elements, accident precursors, and risk events are established through if-then relationships. The potential hazards associated with design choices are evaluated by developing and running visual scripts and assessing design model parameters in BIM. This approach enables architects to track construction risks during their design stage, even without extensive onsite construction experience. In addition, owners can evaluate design decisions considering construction safety risks, and contractors can forecast and monitor risky elements, materials, and locations during construction execution. The research outcomes contribute to enhancing safety risk awareness in the early design phases and support efficient and predictive safety management during construction.

With mass customized production becoming the mainstream, industries are shifting from large-scale manufacturing to flexible and customized production of small batch sizes. Agile manufacturing strategies adopted by SMEs are driving the usage of collaborative robots in today’s factories. Major challenges in the adoption of cobots in the industry are the lack of a highly trained workforce to program the robot to perform complex tasks and integration of robot systems to other smart devices in the factory. In addition, the teaching and simulation by non-robotics experts of many industrial collaborative robot systems like the KUKA LBR iiwa is a major challenge, since these systems are designed to be programmed by robot experts and not by shop floor workers or other nonexperts. This paper describes the research and development activities done for reducing the barriers in operation and ensure holistic integration of LBR iiwa cobot in the assembly on the example of the ESB Logistics Learning Factory. These include a visual programming solution for the easy teaching of various tasks. Robotics tasks are classified based on common robotics applications and application-specific blocks abstracting specific actions are implemented. A factory worker with no programming competency could create robot programs by combining these blocks using a Graphical User Interface. In addition, a simulation solution was developed to visualize, analyse, and optimize robotic workflow before deployment. An autonomous mobile robot is integrated with the LBR iiwa to improve reconfigurability and thus also the productivity. The system as a whole is controlled using an event-driven distributed control system. Finally, the capabilities of the system are analysed based on the design principles of Industrie 4.0 and potential future research ideas are discussed to further improve the system.

Energy Performance Optimization as a Generative Design Tool for Nearly Zero Energy Buildings

引用

Procedia Engineering 2017年 180卷 1178-1185页

作者： Eleftheria Touloupaki Theodoros Theodosiou Laboratory of Building Construction and Building Physics Department of Civil Engineering Aristotle University of Thessaloniki Thessaloniki 54124 Greece

In order to effectively design nearly Zero Energy Buildings, the assessment of energy performance in the early design stages through simulation is an important, although very demanding and complex, procedure. Over the last decades, various tools and methods have been developed to address performance-related design questions, mostly using Multi-Objective Optimization Algorithms. Technological advances have revolutionized the way Architects design and think, automating complex tasks and allowing the assessment of multiple variants at the same time. In this paper, a new nZEB design workflow methodology is proposed, integrating evolutionary algorithms and energy simulation, and its capabilities and current limitations are explored.

New technologies are changing the way engineers work within the construction sector. Newly developed software solutions have provided effective methods to explore the design space at the interface between Structural Engineering and Architecture, allowing more efficient design strategies. These technologies are based on the integration of parametric generation and visualisation of geometries with powerful numerical solvers, employing user-customised routines. While the construction industry is rapidly moving the design of new construction towards a fully digitalised process, the assessment and the analysis of existing structures with such tools are still largely unexplored. In this context, a visual script for the structural assessment of out-of-plane mechanisms in historic masonry structures subject to seismic loading has recently been proposed by the authors. This relies on two successive steps of analysis, which are integrated into a digital work-flow. Datasets describing the geometric configuration of masonry structures are employed to automatically generate a non-linear Finite Element (FE) model and investigate possible collapse modes. A preliminary global analysis is performed using the commercial software ABAQUS CAE. This, in combination with the Control Surface Method (CSM), allows identifying the most likely failure mechanisms which are described by the geometry of the macro-blocks. The parametric modelling of the macro-blocks geometry allows exploring the domain of possible solutions using the upper bound method of limit analysis. A Genetic Algorithms (GA) solver is used to refine the geometry of the macro-blocks and search the minimum of the upper-bound load multipliers, which guarantees equilibrium. The script is implemented in the visual programming environment offered by Rhino3D+Grasshopper. In this paper, a set of parametric analyses considering various input variables such as friction coefficient and opening incidence are performed to verify both the

The visual workflow operate-mode can greatly improve the programming efficiency. visual workflow technology which is brought into the design of remote sensing algorithms can not only control the processing of remote sensing algorithms flexibly, but also greatly improve the reusability of remote sensing algorithms. The principle of remote sensing algorithms visualization lies in the decomposition of remote sensing algorithms. By means of packaging the decomposed algorithms and showing them visually, the algorithm can be processing more efficient. In addition, through the visual platform, the decomposed algorithms can be restructured into new algorithm flow which is composed by a certain number of refined algorithms. Therefore, the composed algorithm can be accelerated through the parallel processing method. Currently, multi-core processors programming is popular. Multi-core processing has been becoming an emerging and high efficient computer technology. The platform will accelerate the processing of the algorithm flow further by using multi-core processing technology.

Graphical Access to Medical Expert Systems: III. Design of a Knowledge Acquisition Environment*)

引用

Methods of Information in Medicine 2018年第3期26卷 78-88页

作者： Joan D. Walton M. A. Musen D. M. Combs C. D. Lane E. H. Shortliffe L. M. Fagan

Knowledge acquisition for expert systems typically is a tedious, iterative process involving long hours of consultation between the domain experts and the computer scientists who serve as knowledge engineers. For well-understood domains, however, it may be possible to facilitate the knowledge acquisition process by allowing domain experts to develop and edit a knowledge base directly. Administration of protocol-directed cancer chemotherapy is such a well-understood application area, and a knowledge acquisition system, called OPAL, has been developed for eliciting chemotherapy-protocol knowledge directly from expert oncologists. OPAL’s knowledge acquisition approach is based on the interactive graphics environment available on current generation workstations. The use of graphics improves the interface by reducing typing, avoiding natural language interpretations, and allowing flexibility in entry sequence. The knowledge in OPAL is displayed using an arrangement of hierarchically related, graphical forms. The position of a particular form in the hierarchy defines the context of the knowledge contained in the form. Intelligent editing programs such as OPAL can streamline the knowledge engineering process for highly structured domains requiring repetitive knowledge entry.

A METHOD FOR EVALUATING THE DAYLIGHTING OF PREMISES USING BIM

LIGHT & ENGINEERING

引用

LIGHT & ENGINEERING 2021年第5期29卷 56-60页

作者： Konstantinov, Alexander P. Natl Res Moscow State Univ Civil Engn NRU MGSU Fed State Budgetary Educ Inst Higher Educ Moscow Russia

The paper presents a method for assessing the daylighting of premises, which can be used directly at the stage of architectural and construction design of buildings in building information model (BIM) software complexes. The calculation method is based on the calculation of the sky factor by constructing a solid angle formed by the calculated point and the light opening of the outer wall. These operations are proposed to be performed automatically using visual programming programs that work together with the BIM complexes. Since the considered calculation method is based on the idea of the physical meaning of the daylight factor, it can be used to evaluate the daylighting according to almost any regulatory method. At the same time, all the data necessary for the calculation can be obtained directly from the building information model. The method is universal and can be used both for the calculation of side and top daylighting, considering the surrounding development. The proposed method can also be used as a tool for finding the best design solution for translucent structures of the designed building based on the requirements of thermal protection, daylighting, and safety.
