Prototypes are described as a successful mechanism to incorporate user-experience design （UX） into Agile de- velopments, but their integration into such developments is not exempt from difficulties. Prototypes and final applications are often developed using different tools, which hinders the collaboration between designers and developers and also compli- cates reuse. Moreover, integrating stakeholders such as clients and users into the Agile process of designing, evaluating, and refining a prototype is not straightforward mainly because of its iterative nature. In an attempt to tackle these problems, this work presents the design and implementation of a new framework in which scripting languages are used to code prototyped behaviors. Prototyping is then treated as a separate aspect that coexists and runs together with final functionality. Using this framework communication is enhanced because designers and developers work in parallel on the same software artifact. Prototypes are fully reused and iteratively added with final functionality while prototyped behaviors are removed. They can be also modified on the fly to implement participatory design techniques.

The decentralization mechanism provides manufacturers and distributors with greater customization and flexibility they need through Internet of Things (IoT)-based industrial collaboration systems (IoT-ICS), but it has brought forward security concerns about the shared data-processing tasks and IoT-based access to services and resources. To address them, we propose a practical blockchain solution to achieve decentralized policy management and evaluation on attribute-based access control (ABAC). By offloading the responsibility of ABAC policy administration and decision making to blockchain nodes, a blockchain-based access control framework, called Policychain, is presented to ensure policy with high availability, autonomy, and traceability. To deliver a solid design, we first present a transaction-oriented policy expression scheme with a well-defined syntax and semantics. The scheme can translate ABAC policies into the blockchain transactions with JavaScript object notation (JSON) syntax and script-based logical expression. We further realize a script-driven policy evaluation by extending blockchain inherent scripting instructions to support attribute acquisition of ABAC entities. Furthermore, we propose a policy lifecycle management scheme from policy creation, renovation, to revocation, in which policies are verified by three validation principles at the transaction level. Finally, we provide sophisticated analysis and experiments to show that our framework is secure and practical for decentralized policy management on ABAC in IoT-ICS.

Object-oriented virtual sample library: a container of multi-dimensional data for acquisition, visualization and sharing

引用

MEASUREMENT SCIENCE AND TECHNOLOGY 2005年第1期16卷 285-291页

Combinatorial methods bring about enormous data not only in size but also in dimension. To handle multi-dimensional data easily, the concept of a virtual container for combinatorially acquired data is demonstrated which is called 'virtual sample library' (VSL). VSL stores the data hierarchically in the order of (1) coordinates in the sample library, (2) names of the measurements performed and (3) data obtained from each measurement. Thus, the stored data are accessed intuitively just by tracing this tree-like structure and are provided for Visualization and sharing with others. This framework is constructed with the aid of an object-oriented scripting language which is good at abstracting complicated data structure. In this paper, after summarizing the problems of handling data acquired from combinatorially integrated samples and the availability of software tools to solve them, the concept of VSL is proposed and its structure and functions are demonstrated on the basis of one set of specific experimental data. Its extensibility as a platform for numerical simulation is also discussed.

Photonics design tool for advanced CMOS nodes

IET OPTOELECTRONICS 2015年第4期9卷 163-167页

Recently, the authors have demonstrated large-scale integrated systems with several million transistors and hundreds of photonic elements. Yielding such large-scale integrated systems requires a design-for-manufacture rigour that is embodied in the 10 000 to 50 000 design rules that these designs must comply within advanced complementary metal-oxide semiconductor manufacturing. Here, the authors present a photonic design automation tool which allows automatic generation of layouts without design-rule violations. This tool is written in SKILL, the native language of the mainstream electric design automation software, Cadence((R)). This allows seamless integration of photonic and electronic design in a single environment. The tool leverages intuitive photonic layer definitions, allowing the designer to focus on the physical properties rather than on technology-dependent details. For the first time the authors present an algorithm for removal of design-rule violations from photonic layouts based on Manhattan discretisation, Boolean and sizing operations. This algorithm is not limited to the implementation in SKILL, and can in principle be implemented in any scripting language. Connectivity is achieved with software-defined waveguide ports and low-level procedures that enable auto-routing of waveguide connections.

Generating ambient behaviors in computer role-playing games

Many computer games use custom scripts to control the ambient behaviors of nonplayer characters. As a result, story authors must write computer code for the game world's hundreds or thousands of NPCs. Creating entertaining, nonrepetitive NPC behaviors without investing substantial programming effort to write customized, nontrivial scripts is challenging. Current computer games have simplistic ambient behaviors for NPCs; it's rare for such characters to interact with each other. To address this, we developed a model that uses generative behavior patterns, which let authors quickly and reliably generate realistic and entertaining NPC scripts. The approach has proven successful, even in the challenging area of creating interactions between NPCs. This article is part of a special issue on interactive entertainment.

Dynamic translation for virtual machine based traffic simulation

引用

SIMULATION MODELLING PRACTICE AND THEORY 2014年 47卷 248-258页

作者： Yu, Bin Zhang, Michael Wang, Zhongren Bian, Dong Tongji Univ Minist Educ Key Lab Rd & Traff Engn Shanghai 200092 Peoples R China Univ Calif Davis Dept Civil & Environm Engn Davis CA 95616 USA Calif Dept Transportat Sacramento CA USA Tongji Univ Sch Transportat Engn Shanghai 200092 Peoples R China

For virtual machine based traffic simulation platforms, the paper proposes a software framework that performs trace-based dynamic translation. Through monitoring the run-time execution status of bytecodes and translating frequently executed bytecodes, also known as hot spots, into equivalent native machine Codes, the framework considerably improves the performance of virtual machine based traffic simulation platforms up to ten times or more, as the experiments showed. For the first time, the presented work clearly exhibits that a seamless combination of the two technologies - dynamic translation and virtual machine could lead to a new generation of applicable traffic simulation platforms. Such a platform not only offers high flexibility in terms of traffic model simulation, but also preserves the ability of conducting numerical computation-intensive simulations generally found in real-life industrial projects.

ScriptEase: A generative/adaptive programming paradigm for game scripting

引用

SCIENCE OF COMPUTER PROGRAMMING 2007年第1期67卷 32-58页

作者： Cutumisu, Maria Onuczko, Curtis McNaughton, Matthew Roy, Thomas Schaeffer, Jonathan Schumacher, Allan Siegel, Jeff Szafron, Duane Waugh, Kevin Carbonaro, Mike Duff, Harvey Gillis, Stephanie Univ Alberta Dept Comp Sci Edmonton AB T6G 2E8 Canada Univ Alberta Fac Educ Edmonton AB T6G 2G5 Canada

The traditional approach to implementing interactions between a player character (PC) and objects in computer games is to write scripts in a procedural scripting language. These scripts are usually so complex that they must be written by a computer programmer rather than by the author of the game story. This interruption in the game story authoring process has two distinct disadvantages: it increases the cost of game production and it introduces a disconnect between the author's intentions and the interactions produced from the programmer's written scripts. We introduce a mechanism to solve these problems. We show that game authors (non-programmers) can generate the necessary scripts for implementing meaningful interactions between the PC and game objects using a three-step process. In the first step, the author uses a generative pattern (concept) to create a high-level description of a commonly occurring game scenario. In the second step, the author uses a standard set of adaptation operations to customize the high-level description to the particular circumstances of the story that is being told. In the third step, the author presses a button that automatically generates scripting code from the adapted pattern. We describe the results of three studies in which a combined total of 56 game story authors used this three-step process to construct Neverwinter Nights game stories, using a tool called ScriptEase. We believe that this generative/adaptive process is the key to future game story scripting. More generally, this article advocates the development of adaptive programming as an alternative to current constructive programming techniques, as well as the application of adaptive programming in many domains.

OpenSeesPy: Python library for the OpenSees finite element framework

引用

SOFTWAREX 2018年 7卷 6-11页

作者： Zhu, Minjie McKenna, Frank Scott, Michael H. Oregon State Univ Sch Civil & Construct Engn 101 Kearney Hall Corvallis OR 97331 USA Univ Calif Berkeley Dept Civil & Environm Engn 760 Davis Hall Berkeley CA 94720 USA

OpenSees, an open source finite element software framework, has been used broadly in the earthquake engineering community for simulating the seismic response of structural and geotechnical systems. The framework allows users to perform finite element analysis with a scripting language and for developers to create both serial and parallel finite element computer applications as interpreters. For the last 15 years, Tcl has been the primary scripting language to which the model building and analysis modules of OpenSees are linked. To provide users with different scripting language options, particularly Python, the OpenSees interpreter interface was refactored to provide multi-interpreter capabilities. This refactoring, resulting in the creation of OpenSeesPy as a Python module, is accomplished through an abstract interface for interpreter calls with concrete implementations for different scripting languages. Through this approach, users are able to develop applications that utilize the unique features of several scripting languages while taking advantage of advanced finite element analysis models and algorithms.

OBLIQ-3D - A HIGH-LEVEL, FAST-TURNAROUND 3D ANIMATION SYSTEM

引用

IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 1995年第2期1卷 175-193页

作者： NAJORK, MA BROWN, MH Systems Research Center Digital Equipment Corporation Palo Alto CA USA

This paper describes Obliq-3D, a high-level, fast-turnaround system for building 3D animations. Obliq-3D consists of an interpreted language that is embedded into a 3D animation library. This library is based on a few simple, yet powerful constructs that allow programmers to describe three-dimensional scenes and animations of such scenes. By virtue of its interpretive nature, Obliq-3D provides a fast-turnaround environment. The combination of simplicity and fast turnaround allows programmers to construct nontrivial animations quickly and easily. The paper is divided into three major parts. The first part introduces the basic concepts of Obliq-3D, using a series of graduated examples. The second part shows how the system can be used to implement Cone Trees. The third part develops a complete animation of Dijkstra's shortest-path algorithm.
