Ja Nein Mit der Einstellung der Arbeit in die Bibliothek bin ich einverstanden. .................................................................................... (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.

Component Diagrams in UML
9. UML Component Diagrams Page 1 of 4 Component Diagrams in UML The previous articles covered two of the three primary areas in which the UML diagrams are categorized (see Article 1)—Static and Dynamic. The remaining two UML diagrams that fall under the category of Implementation are the Component and Deployment diagrams. In this article, we will discuss the Component diagram. Basics The different high-level reusable parts of a system are represented in a Component diagram. A component is one such constituent part of a system. In addition to representing the high-level parts, the Component diagram also captures the inter- relationships between these parts. So, how are component diagrams different from the previous UML diagrams that we have seen? The primary difference is that Component diagrams represent the implementation perspective of a system. Hence, components in a Component diagram reflect grouping of the different design elements of a system, for example, classes of the system. Let us briefly understand what criteria to apply to model a component. First and foremost, a component should be substitutable as is. Secondly, a component must provide an interface to enable other components to interact and use the services provided by the component. So, why would not a design element like an interface suffice? An interface provides only the service but not the implementation. Implementation is normally provided by a class that implements the interface. In complex systems, the physical implementation of a defined service is provided by a group of classes rather than a single class. A component is an easy way to represent the grouping together of such implementation classes. -

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. -

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.

Sysml Distilled: a Brief Guide to the Systems Modeling Language
ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML. -
Systems Engineering with Sysml/UML Morgan Kaufmann OMG Press
Systems Engineering with SysML/UML Morgan Kaufmann OMG Press Morgan Kaufmann Publishers and the Object Management Group™ (OMG) have joined forces to publish a line of books addressing business and technical topics related to OMG’s large suite of software standards. OMG is an international, open membership, not-for-profi t computer industry consortium that was founded in 1989. The OMG creates standards for software used in government and corporate environments to enable interoperability and to forge common development environments that encourage the adoption and evolution of new technology. OMG members and its board of directors consist of representatives from a majority of the organizations that shape enterprise and Internet computing today. OMG’s modeling standards, including the Unifi ed Modeling Language™ (UML®) and Model Driven Architecture® (MDA), enable powerful visual design, execution and maintenance of software, and other processes—for example, IT Systems Modeling and Business Process Management. The middleware standards and profi les of the Object Management Group are based on the Common Object Request Broker Architecture® (CORBA) and support a wide variety of industries.

UML Profile for Communicating Systems a New UML Profile for the Specification and Description of Internet Communication and Signaling Protocols
UML Profile for Communicating Systems A New UML Profile for the Specification and Description of Internet Communication and Signaling Protocols Dissertation zur Erlangung des Doktorgrades der Mathematisch-Naturwissenschaftlichen Fakultäten der Georg-August-Universität zu Göttingen vorgelegt von Constantin Werner aus Salzgitter-Bad Göttingen 2006 D7 Referent: Prof. Dr. Dieter Hogrefe Korreferent: Prof. Dr. Jens Grabowski Tag der mündlichen Prüfung: 30.10.2006 ii Abstract This thesis presents a new Unified Modeling Language 2 (UML) profile for communicating systems. It is developed for the unambiguous, executable specification and description of communication and signaling protocols for the Internet. This profile allows to analyze, simulate and validate a communication protocol specification in the UML before its implementation. This profile is driven by the experience and intelligibility of the Specification and Description Language (SDL) for telecommunication protocol engineering. However, as shown in this thesis, SDL is not optimally suited for specifying communication protocols for the Internet due to their diverse nature. Therefore, this profile features new high-level language concepts rendering the specification and description of Internet protocols more intuitively while abstracting from concrete implementation issues. Due to its support of several concrete notations, this profile is designed to work with a number of UML compliant modeling tools. In contrast to other proposals, this profile binds the informal UML semantics with many semantic variation points by defining formal constraints for the profile definition and providing a mapping specification to SDL by the Object Constraint Language. In addition, the profile incorporates extension points to enable mappings to many formal description languages including SDL. To demonstrate the usability of the profile, a case study of a concrete Internet signaling protocol is presented. -
UML 2001: a Standardization Odyssey
UML 2001: A Standardization Odyssey As the UML reaches the ripe age of four, both its proponents and its critics are scanning the recent changes in the UML 1.3 revision. CRIS KOBRYN In a relatively short period of time the Unified Modeling Language has emerged as the software industry’s dominant modeling language. UML is not only a de facto modeling language standard; it is fast becoming a de jure standard. Nearly two years ago the Object Management Group (OMG) adopted UML as its standard modeling language. As an approved Publicly Available Specification (PAS) submitter to the International Organization for Standardization (ISO), the OMG is proposing the UML specification for international timescales of standards usually conflict with the standardization. It is anticipated that the “fast competitive need to use the latest technology as track” PAS process will complete sometime next early as possible. From a technical perspective, the year, at which time UML will be formally recog- need to achieve consensus encourages “design by nized as an international standard for information committee” processes.
