The document discusses UML with action semantics (xUML), which allows UML models to be executed. It covers key concepts like actions, which are the fundamental unit of computational behavior, and action semantics, which remove assumptions about specific computing environments. xUML models can be used to define executable analysis models. The document also provides an overview of behavioral modeling elements in UML like use cases, and covers the action metamodel which defines how actions work through inputs, outputs, data flow, and control flow. It distinguishes between primitive actions and procedures as an action container.
The document discusses object-oriented approaches to software development. It covers the history of object-oriented programming from the 1950s to modern languages like C++ and Java. It then outlines key concepts of the object-oriented model like abstraction, encapsulation, and modularity. The document also discusses object-oriented programming, the software development life cycle, object-oriented analysis using tools like UML, and object-oriented design.
Graduation defense 'Density & Daylight' by Jasper Moelker (05 Nov 2009)Jasper Moelker
Graduation defense for double degree in Architecture and Building Technology on 'designing with density & daylight'.
Urban plan for the Teleport area in Amsterdam showing how the issue of intensifying land usage can be tackled on left-over spaces within a city. The cluster, building and facade design show on different scales how this concept could be implemented.
This document provides a summary of a master's thesis project focused on redeveloping the center of the Teleport Area in Amsterdam to make it more efficient, continuous, and livable. The study examines the urban context through analysis of zoning, infrastructure, and adjacent areas. Design objectives are to re-connect, intensify use, and humanize the space. A conceptual masterplan proposes a mixed-use, multi-layered approach with housing, offices, shops, and other facilities organized around optimized infrastructure and public spaces. A cluster within the masterplan is then designed in more detail to demonstrate feasibility, focusing on light/visibility, flexibility of mixed programs. Finally, a sample building within the cluster is designed to balance connectivity with
This document discusses using model transformation techniques to superimpose architectural styles. It presents a case study on applying the ACROSET style to a system model via QVT relations. Key points include:
1) Architectural styles can be applied during development by superimposing them using model-driven techniques. This provides semi-automatic support for styles.
2) The ATRIUM methodology supports applying styles during the "Synthesize and Transform" phase using model transformations.
3) QVT relations are well-suited for representing styles due to their declarative nature and ability to manage source and target models.
4) A case study demonstrates defining QVT rules to superimpose the ACRO
A framework is the design of an application or subsystem expressed as a set of abstract classes and the way objects in those classes collaborate. Users build applications using a framework by creating subclasses, configuring objects together, and modifying examples. Frameworks invert control so the reused code calls the user's code. Parts of a framework application include new classes and a script that creates, connects, and parameterizes components.
Programming in UML: An Introduction to fUML and AlfEd Seidewitz
The document discusses programming in UML using the Foundational UML (fUML) standard and the Action Language for fUML (Alf). It provides an overview of fUML and Alf, which define an executable subset of UML and a textual action language for specifying behaviors in UML models. The document uses a motivating example of an e-commerce ordering system to illustrate key concepts of executable UML including activities, actions, structure, and asynchronous communication.
The document discusses the importance of oral language development and its connection to literacy. It covers stages of language development from infancy through elementary school age and conditions that support language learning. Additionally, it addresses components of reading development including phonemic awareness, phonics, sight words, fluency, and comprehension.
This is a one day workshop presentation, primarily on the new OMG Foundational UML specification for executable model semantics, but also discussing extensions for executable SysML (System Modeling Language) models.

This document provides an overview of the Eclipse modeling platform and tools. It discusses Eclipse's open development platform for building and managing software. It also describes Eclipse's Modeling Project, including tools for UML2 modeling and EMF. The tutorial section outlines how to install these tools in Eclipse and develop models. It considers documentation resources and provides personal conclusions on Eclipse versus an alternative tool called EinaGMC.
The Unified Modeling Language (UML) has arguably succeeded in becoming the most commonly used modeling notation for software development. But “modeling” in the software community seems largely to mean simply drawing pictures, either to represent the problem domain or to blueprint a solution, without a precise enough meaning to fully specify the functionality of the system being developed. As a result, the UML standard,S up to and including UML 2.4.1, do not define the semantics of UML models at all precisely.
Nevertheless, there has also long been an interest in models that are more precise, even to the extent that they may be executed in their own right. It has taken a while for this viewpoint to penetrate into the mainstream of UML usage. But there has been in a great deal of work in recent years toward the standardization of the formal semantics of UML models – the “meaning” behind the pictures: the Foundational UML (fUML) specification adopted in 2008; the Action Language for fUML (Alf), adopted in 2010; the UML 2.5 specification (which includes a semantics conformance point for the first time); and the Precise Semantics of UML Composite Structures.
This presentation reviews the state of this work and the implications in practice of bringing real meaning to UML.
Smalltalk in Large-scale Enterprise ArchitecturesESUG
This document discusses using Smalltalk in large-scale enterprise architectures. It proposes a "business-centered" architecture with Smalltalk used for the core business logic component ("hub") and other technologies like Java used for external integrations ("spokes"). The key aspects of this architecture are:
1) All business logic and rules are contained within a single Smalltalk component, isolating that logic from external systems.
2) External systems interact with this business logic component using a publish-subscribe messaging system.
3) Smalltalk is well-suited for the flexible, extensible business logic role because of its close mapping to object-oriented domains and simulation capabilities. This component aims to be an executable model
In this 20 minutes talk presented at the Eclipse Summit Europe 2009, Florian Lautenbacher of the University of Augsburg and Marc Dutoo of Open Wide discuss current shortcomings of technologies like EMF and standards like UML, and show how these can be dealt with using research approaches in the area of aspect-oriented modeling (AOM), allowing e.g. to enrich models with orthogonal sets of information pertaining to different concerns. Several techniques and implementations based on Eclipse products and projects (such as EMF extensibility, secondary models such as EMF GenModel's, the aspect-oriented configuration profiles of the Eclipse technology project Java Workflow Tooling) will be presented. An outlook about current standardization approaches in this area by the OMG completes this session.
Virtual EMF - Standard talk at EclipseCon Europe 2011Hugo Bruneliere
Virtual EMF is a new prototype that allows for the transparent composition, weaving and linking of models. It extends EMF to compose elements from different models into a single virtual model. This virtual model can then be used transparently in standard modeling tools. Virtual EMF also aims to improve scalability by avoiding data duplication and enabling direct access to model elements. The prototype is demonstrated on a use case involving the MoDisco framework for model-driven reverse engineering.
The document discusses object-oriented analysis and design using the Unified Modeling Language (UML). It covers the basic concepts of modeling, including what a model is, why we build models, and principles of visual modeling. It then discusses object-oriented principles like abstraction, encapsulation, modularity and hierarchy. The rest of the document describes the UML and how it can be used to model different aspects of software development, including use case diagrams, class diagrams, sequence diagrams, deployment diagrams, and more.
Applying Aspect-Extended UML Modelling to 'e'DVClub
UML modeling is proposed to document complex testbenches, but it has limitations for representing aspect-oriented languages like e. Specifically, UML was designed for object-oriented systems while e uses units and structs, and e allows for richer extensions than AspectJ which UML tools support. While UML could represent portions of an e testbench, it does not fully capture e's aspect-oriented features or constraints. Therefore, UML may not be the best solution for comprehensive documentation of e testbenches.

Therefore, UML may not be the best solution for comprehensive documentation of e testbenches.
The document discusses modeling with Eclipse. It defines what models and metamodels are, and explains that Eclipse Modeling Framework (EMF) allows defining and manipulating models. EMF can generate Java code from models and provides editors to work with models. Various Eclipse projects like GMF and Xtext allow graphical and textual modeling and code generation from models.
The document is a slide presentation on UML modeling and profiling from a software engineering course. It introduces UML and the concepts of metamodeling. It explains that UML is used to specify, visualize, construct and document software system artifacts. The presentation then outlines the typical steps in UML modeling: 1) modeling use cases, 2) modeling system structure with classes and components, and 3) modeling deployment to hardware nodes.
When talking about modeling, I think there will be a bundle of terms that will come to our mind, UML, domain driven development, DSL, forward/reverse enginerring, MDD, MDA, BPMN. These technology or methodology have been there for years; And obviously, modeling has proven itself to provide value by improving communication, business-alignment, quality, and productivity. Its applicability includes a number of disciplines such as analysis, design, or development. But why aren’t we all doing Model Driven Development yet?
Executable UML (xUML) provides an executable version of UML with a precisely defined semantics for actions. xUML supports the separation of business logic from platform technology through platform independent models (PIMs) that can be automatically transformed into platform specific models (PSMs) through model mappings. Tools such as Kennedy Carter's iUML and Accelerated Technology's BridgePoint allow developers to simulate and test xUML models prior to translation into executable code.
SiriusCon 2015 - Breathe Life into Your Designer!melbats
You have your shiny new DSL up and running thanks to the Eclipse Modeling Technologies and you built a powerful tooling with graphical modelers, textual syntaxes or dedicated editors to support it. But how can you see what is going on when a model is executed ? Don't you need to simulate your design in some way ? Wouldn't you want to see your editors being animated directly within your modeling environment based on execution traces or simulator results?
The GEMOC Research Project designed a methodology to bring animation and execution analysis to DSLs. The companion technologies required to put this in action are small dedicated components (all open-source) at a "proof of concept" maturity level extending proven components : Sirius, Eclipse Debug, Xtend making such features within the reach of Eclipse based tooling. The general intent regarding those OSS technologies is to leverage them within different contexts and contribute them to Eclipse once proven strong enough. The method covers a large spectrum of use cases from DSLs with a straightforward execution semantic to a combination of different DSLs with concurrent execution semantic. Any tool provider can leverage both the technologies and the method to provide an executable DSL and animated graphical modelers to its users enabling simulation and debugging at an early phase of the design.
This talk presents the approach, the technologies and demonstrate it through an example: providing Eclipse Debug integration and diagram animation capabilities for Arduino Designer (EPL) : setting breakpoints, stepping forward or backward in the execution, inspecting the variables states... We will walk you through the steps required to develop such features, the choices to make and the trade-offs involved. Expects live demos with simulated blinking leds and a virtual cat robot ! This talks presents also xCapella an industrial use case onwhich the Gemoc methodology was applied.
This talks was presented at SiriusCon 2015 in collaboration with Jérôme Le Noir from Thales.

This document discusses object-oriented modeling and the Unified Modeling Language (UML). It introduces key concepts in modeling including systems, models, and views. Models abstract and simplify a system, while views depict selected aspects of a model. The document then discusses why software needs to be modeled, and introduces concepts, types, and classes in software modeling. It describes the relationship between the application domain and solution domain in object-oriented modeling. Finally, it provides an overview of commonly used UML diagrams including use case diagrams, class diagrams, sequence diagrams, statechart diagrams, and activity diagrams.
The document discusses Object Oriented Analysis and Design (OOAD) using the Unified Modeling Language (UML). It provides an introduction to the UML, explaining that it was created to provide a common language for software engineering. The UML can be used within various development processes, such as the waterfall model, spiral model, iterative frameworks, and Rational Unified Process. The document then covers object orientation concepts, an overview of UML diagrams, and how UML can be applied during analysis and design phases of the software development lifecycle.
This document provides an introduction to structural and use case modeling with the Unified Modeling Language (UML). It outlines a tutorial series on UML that covers introduction, behavioral modeling, and advanced modeling. The document discusses why modeling is useful, provides an overview of UML's goals and evolution, and describes some of UML's foundational concepts including its building blocks, well-formedness rules, and unifying concepts.
The document discusses the need for an executable version of the Unified Modeling Language (UML) called xUML. It notes that while UML 1.x describes system behavior, it is not fully executable because it lacks precise semantics for actions. xUML addresses this by defining a precise action semantics language and process to allow UML models to be executed, validated, and automatically generated into code. An executable UML provides benefits like early verification of requirements, improved quality through objective criteria, and more fun for analysts.

Polyglot and Poly-paradigm Programming for Better Agilityelliando dias
This document discusses the benefits of polyglot and poly-paradigm programming approaches for building more agile applications. It describes how using multiple languages and programming paradigms can optimize both performance and developer productivity. Specifically, it suggests that statically-typed compiled languages be used for core application components while dynamically-typed scripting languages connect and customize these components. This approach allows optimizing areas that require speed/efficiency separately from those requiring flexibility. The document also advocates aspects and functional programming to address cross-cutting concerns and concurrency challenges that arise in modern applications.
This document discusses JavaScript libraries and frameworks. It provides an overview of some popular options like jQuery, Prototype, Dojo, MooTools, and YUI. It explains why developers use libraries, such as for faster development, cross-browser compatibility, and animation capabilities. The document also discusses how libraries resemble CSS and use selector syntax. Basic examples are provided to demonstrate common tasks like hover effects and row striping. Factors for choosing a library are outlined like maturity, documentation, community, and licensing. The document concludes by explaining how to obtain library code from project websites or Google's AJAX Libraries API.

The overall goals are to create an inexpensive device that can provide educational resources in developing areas.
Ragel is a parser generator that compiles to various host languages including Ruby. It is useful for parsing protocols and data formats and provides faster parsing than regular expressions or full LALR parsers. Several Ruby projects like Mongrel and Hpricot use Ragel for tasks like HTTP request parsing and HTML parsing. When using Ragel with Ruby, it can be compiled to Ruby code directly, which is slow, or a C extension can be written for better performance. The C extension extracts the parsed data from Ragel and makes it available to Ruby.
