(Ort, Datum) (Unterschrift) Abstract The development of a game engine is considered a non-trivial problem. [3] The architecture of such simulation software must be able to manage large amounts of simulation objects in real-time while dealing with “crosscutting concerns” [3, p. 36] between subsystems. The use of object oriented paradigms to model simulation objects in class hierar- chies has been reported as incompatible with constantly changing demands dur- ing game development [2, p. 9], resulting in anti-patterns and eventual, messy re-factoring. [13] Alternative architectures using data oriented paradigms re- volving around object composition and aggregation have been proposed as a result. [13, 9, 1, 11] This thesis describes the development of such an architecture with the explicit goals to be simple, inherently compatible with data oriented design, and to make reasoning about performance characteristics possible. Concepts are for- mally defined to help analyze the problem and evaluate results. A functional implementation of the architecture is presented together with use cases common to simulation software. Zusammenfassung Die Entwicklung einer Spiele-Engine wird als nichttriviales Problem betrach- tet. -
Using the UML for Architectural Description?
Using the UML for Architectural Description? Rich Hilliard Integrated Systems and Internet Solutions, Inc. Concord, MA USA [email protected] Abstract. There is much interest in using the Unified Modeling Lan- guage (UML) for architectural description { those techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. IEEE P1471, the Recommended Practice for Architectural Description, represents an emerging consensus for specifying the content of an architectural descrip- tion for a software-intensive system. Like the UML, IEEE P1471 does not prescribe a particular architectural method or life cycle, but may be used within a variety of such processes. In this paper, I provide an overview of IEEE P1471, describe its conceptual framework, and investigate the issues of applying the UML to meet the requirements of IEEE P1471. Keywords: IEEE P1471, architectural description, multiple views, view- points, Unified Modeling Language 1 Introduction The Unified Modeling Language (UML) is rapidly maturing into the de facto standard for modeling of software-intensive systems. Standardized by the Object Management Group (OMG) in November 1997, it is being adopted by many organizations, and being supported by numerous tool vendors. At present, there is much interest in using the UML for architectural descrip- tion: the techniques by which architects sketch, capture, model, document and analyze architectural knowledge and decisions about software-intensive systems. Such techniques enable architects to record what they are doing, modify or ma- nipulate candidate architectures, reuse portions of existing architectures, and communicate architectural information to others. These descriptions may the be used to analyze and reason about the architecture { possibly with automated support. -

ABSTRACT realistic experiences necessary to a VR scene, but not asset creation In this paper we present AffordIt!, a tool for adding affordances (a situation described in Hughes et al. [17]) which are needed to to the component parts of a virtual object. Following 3D scene build a virtual scene. To alleviate this problem, recent research has been focusing on frameworks to ease users’ authoring process as reconstruction and segmentation procedures, users find themselves with complete virtual objects, but no intrinsic behaviors have been seen in [9, 12, 35]. 3D scene reconstruction [32, 34, 44, 49] provides assigned, forcing them to use unfamiliar Desktop-based 3D editing a suitable solution to the problem. Initially a 3D reconstructed tools. AffordIt! offers an intuitive solution that allows a user to environment will be composed of a continuous mesh which can be segmented via autonomous tools as shown in George et al. [10] and select a region of interest for the mesh cutter tool, assign an intrinsic behavior and view an animation preview of their work. -

Drawing UML with PlantUML PlantUML Language Reference Guide (Version 1.2021.2) PlantUML is a component that allows to quickly write : • Sequence diagram • Usecase diagram • Class diagram • Object diagram • Activity diagram • Component diagram • Deployment diagram • State diagram • Timing diagram The following non-UML diagrams are also supported: • JSON Data • YAML Data • Network diagram (nwdiag) • Wireframe graphical interface • Archimate diagram • Specification and Description Language (SDL) • Ditaa diagram • Gantt diagram • MindMap diagram • Work Breakdown Structure diagram • Mathematic with AsciiMath or JLaTeXMath notation • Entity Relationship diagram Diagrams are defined using a simple and intuitive language. 1 SEQUENCE DIAGRAM 1 Sequence Diagram 1.1 Basic examples The sequence -> is used to draw a message between two participants. Participants do not have to be explicitly declared. To have a dotted arrow, you use --> It is also possible to use <- and <--. That does not change the drawing, but may improve readability. Note that this is only true for sequence diagrams, rules are different for the other diagrams. @startuml Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response Alice -> Bob: Another authentication Request Alice <-- Bob: Another authentication Response @enduml 1.2 Declaring participant If the keyword participant is used to declare a participant, more control on that participant is possible. The order of declaration will be the (default) order of display. Using these other keywords to declare participants -

Anderson APECS: Polychrony based End-to-End Embedded System Design and Code Synthesis Matthew E. Anderson (ABSTRACT) The development of high integrity embedded systems remains an arduous and error-prone task, despite the efforts by researchers in inventing tools and techniques for design automa- tion. Much of the problem arises from the fact that the semantics of the modeling languages for the various tools, are often distinct, and the semantics gaps are often filled manually through the engineer's understanding of one model or an abstraction. This provides an op- portunity for bugs to creep in, other than standardising software engineering errors germane to such complex system engineering. Since embedded systems applications such as avionics, automotive, or industrial automation are safety critical, it is very important to invent tools, and methodologies for safe and reliable system design. Much of the tools, and techniques deal with either the design of embedded platforms (hardware, networking, firmware etc), and software stack separately. The problem of the semantic gap between these two, as well as between models of computation used to capture semantics must be solved in order to design safer embedded systems. -

Component Diagrams
1.COMPONENT DIAGRAMS 2. PACKAGE DIAGRAMS What is a component? – A component is an autonomous unit within a system – UML component diagrams enable to model the high-level software components, and the interfaces to those components – Important for component-based development (CBD) – Component and subsystems can be flexibly REUSED and REPLACED – UML components diagrams are Implementation diagrams i.e., it describe the different elements required for implementing a system Example – When you build a house, you must do more than create blueprints – you've got to turn your floor plans and elevation drawings into real walls, floors, and ceilings made of wood, stone, or metal. – If you are renovating a house, you'll reuse even larger components, such as whole rooms and frameworks. – Same is the case when we develop software…. COMPONENT NOTATION – A component is shown as a rectangle with – A keyword <<component>> – Optionally, in the right hand corner a component icon can be displayed – A component icon is a rectangle with two smaller rectangles jutting out from the left-hand side – This symbol is a visual stereotype – The component name Component types Components in UML could represent – logical components (e.g., business components, process components) – physical components (e.g., EJB components, COM+ and .NET components) Component ELEMENTS – A component can have – Interfaces An interface represents a declaration of a set of operations – Usage dependencies A usage dependency is relationship which one element requires another element for its full -
UML Basics: the Component Diagram
English Sign in (or register) Technical topics Evaluation software Community Events UML basics: The component diagram Donald Bell ([email protected]), IT Architect, IBM Corporation Summary: from The Rational Edge: This article introduces the component diagram, a structure diagram within the new Unified Modeling Language 2.0 specification. Date: 15 Dec 2004 Level: Introductory Also available in: Chinese Vietnamese Activity: 259392 views Comments: 3 (View | Add comment - Sign in) Average rating (629 votes) Rate this article This is the next installment in a series of articles about the essential diagrams used within the Unified Modeling Language, or UML. In my previous article on the UML's class diagram, (The Rational Edge, September 2004), I described how the class diagram's notation set is the basis for all UML 2's structure diagrams. Continuing down the track of UML 2 structure diagrams, this article introduces the component diagram. The diagram's purpose The component diagram's main purpose is to show the structural relationships between the components of a system. In UML 1.1, a component represented implementation items, such as files and executables. Unfortunately, this conflicted with the more common use of the term component," which refers to things such as COM components. Over time and across successive releases of UML, the original UML meaning of components was mostly lost. UML 2 officially changes the essential meaning of the component concept; in UML 2, components are considered autonomous, encapsulated units within a system or subsystem that provide one or more interfaces. Although the UML 2 specification does not strictly state it, components are larger design units that represent things that will typically be implemented using replaceable" modules. -
