It focuses on an original process for the identification and the formalization of the instructional language of LMS systems. This process takes into account two complementary viewpoints: the user-centered viewpoint based on the Human Machine Interfaces HMI analysis and the techno-centered viewpoint primarily based on the database analysis. We illustrate this process by an example of experimentation conducted on Moodle platform.
Traceability is a technique to ease determining the impact of changes in the design of software, to support their integration, to preserve knowledge, and to assure the quality and accuracy of the overall system. In this paper, an approach that considers traceability in the context of model-driven development of Home Automation HA systems is presented. This combination enables the development of tools with techniques for improving the quality both of the process and of the models obtained.
To obtain these advantages we have developed a tool that provides users with traceability reports after applying model transformations. These reports enable developers to study whether all requirements have been considered, the impact of changes, and how they are considered both in architectural decisions and code implementations. Business and IT alignment remains an ongoing concern for organizations. In this paper, we propose a set of technologies and concepts - notably goals and computable functions which can be used to provide a measure of equivalence between as-is and to-be enterprise architectures.
The demand for medical device software continues to grow and there is an associated increase in its importance and complexity. This paper discusses medical device software process assessment and improvement. It outlines Medi SPICE, a software process assessment and improvement model which is being developed to meet the specific safety-critical and regulatory requirements of the medical device domain. It also details the development of a subset of the Medi SPICE process reference model for inclusion in the next release of the IEC standard: Medical device software - Software life cycle processes.
IEC is a key standard for medical device software development and is approved by many national regulatory bodies including the Food and Drug Administration in the United States and the European Union. This paper also outlines 3 lightweight software process assessment methods which have been developed in tandem with Medi SPICE.
In model driven software development, the correctness of models is one of the most important issues to construct high quality software in high productivity. Numerous research has been done to verify the correctness of those models. Conventional research mainly focuses on individual models, or at most the relationships between two individual models. However, the models must be correct as a whole set. This paper presents a Color Petri Net CPN based formal approach to verifying the behavioral correctness of UML models depicted by three different kinds of diagrams, namely state machine, activity, and sequence diagrams.
This approach defines the correctness of a set of models from three different perspectives. The first perspective is the completeness that assures the syntactical correctness of the set. The second is the consistency that claims no conflicts between heterogeneous UML models. And the last is the soundness that represents the internal correctness of each model in the set. This paper introduces a goal-oriented framework which consists of generic and specific model repositories, and of methodology for integrated change management of business and IT evolutions.
Is based on model compositions and traceability assessments of goal-oriented and scenario models. It contains a versioning-based cooperative work environment for business analysts to generate strategy decisions and simulations, themselves. The techniques and tools used are from the User Requirements Notation standard for requirements engineering and its supporting tools.
These rise the generic aspect of the framework. An instantiation of framework for B2B change management with empirical validation within an SME, has been done. In a long way, this framework will be a base on a more complex system configuration control framework. Nowadays, large part of the efforts in software development are focused on achieving systems with an as high as possible level of adaptation. With the traditional technique of model-driven development this can be largely accomplished.
The inconvenience of these techniques however, is that the models are usually manipulated at design-time by means of fixed transformation. Furthermore, the transformations that manipulate these models cannot change dynamically according to the current execution context. This paper presents a transformation pattern aimed to adapt architectural models at runtime, this means that these models may change dynamically at runtime. The transformations that produce this model adaptation are not fixed, but dynamically composed by selecting the most appropriate set of rules from those available in a repository.
As an example scenario for the application of these transformations, we chose architectural models representing component-based UIs. Cloud computing environments, especially the PaaS environments, are one of the most promising platforms for high capacity and low cost transaction processing. Therefore, we need to evaluate whether the cloud environment currently considered provides enough capability for our data integrity requirements.
This paper presents a Colored Petri Net CPN based approach to modeling and evaluating generalized transaction systems including cloud environments. In this paper we propose leveraging existing frameworks for automated web application development, in the style of Ruby on Rails, Grails and Spring Roo, for their use within a Model-Driven Engineering process. Our approach automates the construction of domain-specific generators for web applications in particular domains. These generators are able to synthesize web applications using Spring Roo, starting from annotated models.
In this way, designers of web applications do not need to be proficient in web automation frameworks, but they can benefit from the use of domain-specific, intuitive models. We illustrate our approach by generating an application to edit Eclipse Modelling Framework EMF models through the web. Service-based architectures implement business processes as technical software services to develop enterprise software. As a consequence of frequent business and technical change cycles, the architect requires a reuse-centered approach to systematically accommodate recurring changes in existing software.
We propose architecture change mining as a complementary phase to a systematic architecture change execution. To foster reuse, a pattern catalogue maintains an updated collection with once-off specification for identified pattern instances. This allows us to exploit change pattern as a generic, first class abstractions that can be operationalised and parameterised to support reuse in architecture-centric software evolution.
Refactoring in several cases modifies the interface expected by the clients. These clients also include unit tests that make use of the refactored program entities and therefore get affected. But the key difference between an ordinary client and a unit test is the intent of use and a stronger association with the refactored class. A client makes use of the functionality offered by the system and completes its function. Whereas, a unit test verifies the functionality in terms of actual and expected outcomes. In the context of refactoring, a unit test is far more critical as it is the only safety net available to verify the impact of refactoring.
Moreover, Unit tests are tightly coupled to the modules under test. We demonstrate through most commonly used refactorings that there is a need to enhance the existing refactoring support for Java to include the specific adaptation mechanism for unit tests that eradicates the effect of refactoring and also improves the internal structure of test code.
Model driven engineering has been shown to be a useful framework to enrich the quality of software. Metamodeling and model transformation have opened the door to specifying data models and manage it in a formal and solid way. These favourable features are particularly welcome in collaborative development, where we need a data model suitable for specifying information from different sources, and which can also facilitate the integration of this heterogeneous information to a global data model.
In this paper we introduce a metamodel based on the notion of functional dependencies and we propose to use model driven engineering for the development of model transformation based on the SLFD logic. NET platform.
NET programs, thus unlocking existing routines to. NET developers and making. In a preliminary experiment, we made the advantage of interoperability visible: we achieved a 5-fold speedup by calling. Instead of manually creating graphical user interfaces UIs , automatically generating them is desirable, especially since UIs are needed today for diverse devices like PCs and smartphones. The basis for such automated generation can be a UI specification, but most of the related research takes task models as input, which are on a higher level of abstraction.
More recently, another modeling language employing discourse-based models for specifying communicative interaction has been proposed, which completely abstracts from specifics of a particular UI and even its type. From such models, UIs can be generated automatically through model transformations. Some research, however, claims that UIs can be generated from use cases. While it would be desirable to utilize such a form of requirements definition without having to create another specification, we found that these approaches actually use additional information attached to the use cases, usually UI-related attachments.
In addition to contrasting different kinds of specifications, we propose a synthesis through a combination. In fact, we found that discourse-based models can be also viewed as specifying classes of scenarios, i. Uzo Okafor, Ramesh K. Karne, Alexander L. Wijesinha and Bharat S. SQLITE is a popular small open-source database management system with many versions that run on popular platforms. Since a bare PC does not provide any form of operating system or kernel support, bare PC applications need to be completely self-contained with their own interfaces to the hardware.
Such applications are characterized by small code size, and have inherent security and performance advantages due to the absence of a conventional operating system. We present the current state of this work and identify several important issues that need further research. This paper describes an implementation framework for component-based applications that provides developers with great control over application concurrency number of threads and their characteristics , the computational load assigned to them, and allows the temporal analysis of the applications developed with the framework.
The paper presents an improved version of a framework previously developed, putting it in the context of a global Model-Driven Software Development approach for developing, analyzing and generating code for reactive applications. Many user requirements and UML models are similar even if identical, but their application backgrounds are different.
It is a straight and feasible way to mine those similar UML models for a model warehouse and reuse them so as to improve software development efficiency. The key point in the idea is to measure the similarity of UML models. We present a Level Edit Distance method to solve the problem. However, our method concentrates on the pure structural similarity of UML models in XMI format, namely, the semantic information is ignored. The former needs only one primitive operation whereas the later needs three. Our preparatory experimental results show that the LED can keep almost the same distance distribution with the traditional ED and is a little faster than the latter.
We are going to improve the capability of the LED and combine it with a semantic-considered method in order to precisely evaluate the similarity of user requirements. Objectives of the project's initial phase include designing and prototyping a subsystem for grid modelling, optimization and simulation GMOS. The GMOS subsystem implements state-of-the-art software kernels for the simulation of water distribution networks, including modules for the calibration of the hydraulic model and for an optimal partitioning of the grid. This paper illustrates general findings in applying model-driven software engineering to the architecture and design of the GMOS subsystem which largely abstract from the specific nature of the distribution grid as they could equally apply to the modelling, optimization and simulation of gas and electricity distribution networks.
This paper seeks to elaborate on the disambiguation of Persian words with the same written form but different senses using a combination of supervised and unsupervised method which is conducted by means of thesaurus and corpus. The present method is based on a previously proposed one with several differences. These differences include the use of texts which have been collected by supervised or unsupervised method. In addition, the words of the input corpus were stemmed, and in the case of those words whose different senses have different roles in the sentence, the role of the word in the input sentence was considered for disambiguation.
In this paper we propose using Timed Observation Theory as a powerful framework for model-based diagnosis. It provides a global formalism for modeling a dynamic tool TOM4D designed to characterize and compute diagnoses of a structure under investigation. The paper presents a process algebraic approach to formal specification and verification of social networks. They are described using the Calculus of Communicating Systems and we reason and verify such formal systems by using directed model checking, which uses AI-inspired heuristic search strategies in order to improve model checking techniques.
Mario L. Bernardi, Marta Cimitile and Fabrizio M. This is an important issue in the context of MDE considering thatWAs are often used to support users in the execution of business processes.
Computer Science Department
In this paper, we propose the integration of three MDE metamodels used to represent the structure of information, service and presentation layers of a WA with the metamodel of Declare, a declarative language for business process rapresentation. The declarative nature of Declare allows us to combine an efficient roundtrip engineering support with the advantages of an MDE approach. We present and discuss a case study where the proposed approach is used to develop a typical online shopping application with the aim to validate and verify the feasibility and the effectiveness of the approach.
We propose a new programming language called INI, which combines both event-based and rule-based styles and is suitable for building concurrent and context-aware reactive applications. In our language, both events and rules can be defined intuitively and explicitly, in a stand-alone way or in combination. Events in INI can run in parallel in order to handle multiple tasks concurrently and may trigger actions defined in related rules.
Besides, events can interact with the execution environment to adjust their behaviors if necessary and response to unpredicted changes. This makes INI a convenient language to write many kinds of programs which need to take advantages of concurrency and context-awareness, such as embedded software, interactive applications, sensors applications, robotic systems, etc.
Building software tools to support a new modeling formalism is a complex, error prone and time consuming task. Previous experiences have taught us that maintainability and portability are key issues which are poorly supported when development is realized in and ad-hoc manner. To overcome these limitations, we are investigating a meta-model driven approach for specifying at design phase not only the structural part of a process meta-model, but also its operational semantics in order to derive in a systematic manner an enactment engine.
In this paper, we show how process model operational semantics are expressed by defining the architecture of an interactive enactment engine, and how the engine's behavior is formally specified using an event based notation. This paper presents the case for constraints requirements formalised as logical assertions as the key starting point for software development. We describe how system development from such constraints can be automated. Generic programming is a mechanism for re-using code by abstracting specific types used in classes and programs.
In this paper, we present a mechanism for adding generic programming in dynamically typed languages, showing how programmers can benefit from generic programming. Furthermore, we enhance the expressiveness of generic programming with reverse generics, a mechanism for automatically deriving new generic code starting from existing non-generic one. We implemented generics and reverse generics in Pharo Smalltalk, and we successfully used them to solve a problem of reusing unit test cases.
This helped us to identify a number of bugs and anomalies in the stream class hierarchy. Various techniques for testing embedded software have been proposed as a result of the increased need for high quality embedded systems. However, it is hard to perform accurate testing with these techniques on failures that can occur unexpectedly in a real environment, because most of the tests are performed in software development environment. In this paper, we propose an aspect-based On-the-Fly testing. The purpose of which is to test the functionalities and non-functionalities of embedded software using aspect-oriented programming at run-time in a real environment.
Our proposed technique provides some advantages of prevention of software malfunction in a real environment and high reusability of test code. The main goal of concept-oriented programming COP is describing how objects are represented and accessed. References object locations in COP are made first-class elements responsible for many important functions which are difficult to model via objects.
COP rethinks and generalizes such primary notions of object-orientation as class and inheritance by introducing a novel construct, concept, and a new relation, inclusion. They make it possible to describe many mechanisms and patterns of thoughts currently belonging to different programming paradigms: modeling object hierarchies prototype-based programming , precedence of parent methods over child methods inner methods in Beta , modularizing cross-cutting concerns aspect-oriented programming , value-orientation functional programming.
Free Composition Instead of Language Dictatorship. Historically, programming languages have been—benevolent—dictators: reducing all possible semantics to specific ones offered by a few built-in language constructs. Over the years, some programming languages have freed the programmers from the restrictions to use only built-in libraries, built-in data types, and builtin type-checking rules. Even though—arguably—such freedom could lead to anarchy, or people shooting themselves in the foot, the contrary tends to be the case: a language that does not allow for extensibility is depriving software engineers of the ability to construct proper abstractions and to structure software in the most optimal way.
Therefore the software becomes less structured and maintainable than would be possible if the software engineer could express the behavior of the program with the most appropriate abstractions. The idea proposed by this paper is to move composition from built-in language constructs to programmable, first-class abstractions in a language. We discuss several prototypes of the Co-op language, which show that it is possible, with a relatively simple model, to express a wide range of compositions as first-class concepts.
Farzad Salehi, Stefan D. Bruda, Yasir Malik and Bessam Abdulrazak. Service discovery is very important in realizing the concept of pervasive computing. Consequently, service discovery protocols must be able to work in the heterogeneous environment offered by pervasive computing. Remote service discovery in particular has not been properly achieved so far. In an attempt to remedy this we propose a new architecture for enabling typical local service discovery mechanisms without the ability of remote service discovery to discover services remotely.
Our architecture uses Universal Plug and Play UPnP as an example of local service discovery protocols, and Gnutella as an example of peer-to-peer distributed search protocols. We introduce a module called service mirror builder to the UPnP protocol, and a remote communication protocol over a Gnutella network. As a consequence, UPnP networks become able to discover services in remote networks that is, remote service discovery.
Infrastructure-as-a-service IaaS clouds, such as Amazon EC2, offer pay-for-use virtual resources on-demand. This allows users to outsource computation and storage when needed and create elastic computing environments that adapt to changing demand. However, existing services, such as cluster resource managers e. Torque , do not include support for elastic environments. Furthermore, no recontextualization services exist to reconfigure these environments as they continually adapt to changes in demand.
In this paper we present an architecture for a large-scale elastic cluster environment. We also develop a lightweight REST-based recontextualization broker that periodically reconfigures the cluster as nodes join or leave the environment. Our solution adds nodes dynamically at runtime and supports MPI jobs across dis-tributed resources. We demonstrate the ability of our solution to create multi-cloud deployments and run batch-queued jobs, recontextualize node clusters within one second of the recontextualization period, and scale to over nodes in less than 15 minutes.
Software product lines SPL are of obvious significance to the software development process as it mostly rely on identifying commonalities within an application domain to facilitate component integration for building new software product. The main focus of SPL is the development of software systems in single domain where some basic functionality are re-user all over the developed systems. However, when it comes to cross-domains component re-use, SPL development processes always encounter difficulties in integrating heterogeneous components where different architectural assumptions are need to incorporate them into a system.
This paper establishes a significant distinction of component interfaces and utilizes it to derive the building of a SPL that can support developing cross-domains software re-use. Nowadays, the impact of Web Services is quickly increasing because of transactions through Internet. This makes it necessary to pay special attention to testing this type of software and presents a challenge for traditional testing techniques, due to the inclusion of specific instructions for concurrency, fault and compensation handling, and dynamic service discovery and invocation.
Metamorphic Testing has proved useful to test and improve the quality of traditional imperative programs. This work presents an procedure for applying Metamorphic Testing to Web Services compositions, proposes an architecture and analyzes a case study with promising results. Web application is getting great prosperous while web browser is becoming one of the most important platforms not only on PCs, but also on mobile devices. And web application producing and consuming are going through a process of transformation sharped by the trends including Cloud computing, social networking, online application store, etc.
In this paper, we gave our insight on the web application paradigm, discussing its aspects of development, deployment, distribution, economic model, cloud platform, social diffusion and so on, and represent both the architecture and implementation based on our understanding.
The proposed extension provides a classification of the Non-functional NLP properties which promotes the representation of their relationships. The growing success of mobile devices is enabling a new class of applications that overcome the traditional models of desktop applications and web browsing, and embrace entirely new ways of computing.
Service oriented computing and the rapidly growing power of mobile devices are the key ingredients of a new generation of low-cost, lightweight applications where mobile devices are no longer intended as a means to access server-side data and functionality, but as a source of services that other devices can discover and invoke.
In this paper we introduce Sip2Share, a middleware that allows for publishing, discovering and invoking services in a peer-to-peer network of Android devices. A characteristics of our middleware is that services are advertised, discovered and called using the same native mechanisms of the Android platform, i. Web service systems grow larger with age whenever organizations add new services to existing systems.
As is the case with other types of software, very large Web service systems are difficult to understand and maintain and are therefore undesirable. A couple of measures have been proposed in literature that can be used to analyze the size attribute of Web service systems with the goal of aiding designers and managers in the management of such software.
However, these measures target only simple to medium-sized services, and are not effective for very large cross-enterprise services. In this paper, we propose some size measures for evaluating the size of Web service systems irrespective of their granularity, thereby providing useful information to business process managers.
Web service is a new paradigm of internet software and distributed computing. With the growth of web services number, the capability to find the optimal service which can substitute the fault service from different communities represents a very hard operation. The researched service must have the same functionalities of the fault service and the highest quality of service scale. In this paper, we propose heuristic method based onBees Algorithm to find the optimal service which can substitute the fault service.
In our approach, we design a distributed environment based on Peer-to-Peer architecture in order to present distributed communities which are considered as flowers and research requests as bees. Software as a Service SaaS becomes a very important trend in software engineering. SOS implies that the software will automatically build and accomplish the executive entity according to the user requirements.
The DMS Arc is a knowledge based service composition system that aims to encapsulate basic Data Mining functions into meta services and automatically combine those services according to the stored knowledge models to fulfil a specific Data Mining requirement. We present some key issues that place in the SOS service cycle. The DMS Arc project is still on developing, and will be published as a public facility in a Cloud Computing environment. Today, service oriented architectures SOA has received much interest. In this position paper, we present an agile approach for the development of SOA with the respect of the principles of agile methods.
