This paper presents BIOS (acronym for Biologically Inspired Optimization System), an object-oriented framework written in C++, aimed at heuristic optimization with a focus on Surrogate-Based Optimization (SBO) and structural problems. The use of SBO to deal with structural optimization has grown considerably in recent years due to the outstanding gain in efficiency, often with little loss in accuracy. This is especially promising when adaptive sampling techniques are used. However, many issues are yet to be addressed before SBO can be employed reliably in most optimization problems. In that sense, continuous experimentation, testing and comparison are needed, which can be more easily carried out in an existing framework. The architecture is designed to implement conventional nature inspired algorithms and Sequential Approximated Optimization (SAO). The system aims to be efficient, easy to use and extensible. The efficiency and accuracy of the system are assessed on a set of benchmarks, and on the optimization of functionally graded structures. Excellent results are obtained.

Software measures play an eminent role in the evaluation of quality of a Web-based application. Increased dependency on Web-based applications enhanced the need to evaluate Web quality parameters. A poor quality Web application fails to fulfill customer's implicit and explicit requirements resulting in poor customer acceptance. Many frameworks have so far been proposed for measurement of quality parameters of Web-based applications but they lack in one way or other. Most of the existing frameworks deal with narrow range of quality characteristics or is limited to a specific Web-based application perspective. Based on the limitations of the current frameworks, this paper proposes a new generic conceptual object-oriented framework multi-attribute quality model which scientifically categorize quality characteristics and its sub-characteristics based on different perspectives and usage of Web applications. The main concept of the newly proposed framework is to analyze and expand the previously established quality characteristics in Web-based applications. The approach is chosen due to the diverse and impulsive nature of the Web applications. For designing the framework ISO/IEC 9126 framework is used as reference.

In this work, we present a simultaneous untangling and smoothing technique for quadrilateral and hexahedral meshes. The algorithm iteratively improves a quadrilateral or hexahedral mesh by minimizing an objective function defined in terms of a regularized algebraic distortion measure of the elements. We propose several techniques to improve the robustness and the computational efficiency of the optimization algorithm. In addition, we have adopted an object-oriented paradigm to create a common framework to smooth meshes composed by any type of elements, and using different minimization techniques. Finally, we present several examples to show that the proposed technique obtains valid meshes composed by high-quality quadrilaterals and hexahedra, even when the initial meshes contain a large number of tangled elements.

In a dynamic environment, a manufacturing system should be reconfigurable to make the products with lot size of one and a high product mix in mass customization. A manufacturing system is continuously evolved to make new products at different time scales and ensure uninterrupted productions when internal or external changes occur. System evolution relates to add, remove, upgrade components, and reconfigure the system at different levels and scopes. However, scientific methods and tools are lacking to support designers in reconfiguring a system subject to given changes. This becomes a big hurdle to adopt automated solutions in small- and medium-sized enterprises. To support system reconfiguration, we propose a generic framework and methods to assess the performance of heterogeneous robotic systems or components. The proposed methods can also help 1) designers to select components for an integrated solution based on the needs and 2) robot manufacturers to identify the weaknesses of their products.

An object-oriented computational framework for the simulation of variably saturated flow in soils, using a reduced complexity model

引用

ENVIRONMENTAL MODELLING & SOFTWARE 2012年 38卷 191-202页

作者： Anagnostopoulos, Grigorios G. Burlando, Paolo Swiss Fed Inst Technol Inst Environm Engn CH-8093 Zurich Switzerland

A simple and efficient computational modelling framework is presented for the simulation of variably saturated flows in porous media, which is not based on a conventional numerical solution of the Richards' equation. The computational domain is discretised with a regular grid and simple rules govern the flow dynamics. Each cell can have distinct hydraulic properties and its state depends only on the state of its neighbouring cells. These concepts make the simulation of large-scale variably saturated flow in heterogeneous media easier and computationally more efficient. Due to its object oriented design, the presented framework is very flexible and easily extensible and can be used for various engineering applications (e.g. prediction of rainfall-induced landslides, water and solute transport in agricultural soils), where the simulation of variably saturated flow is crucial. The modelling framework has been validated with experimental results and analytical solutions for 2-D and 3-D problems available from the literature, showing very good agreement even in cases where strong non linearities existed.

object-oriented frameworks have become a popular paradigm used to improve the software development lifecycle. They promote reuse by providing a semi-complete architecture that can be extended through an instantiation process to integrate the needs of the new software application. Instantiation processes are typically enacted in an ad-hoc manner, which may lead to tedious and error-prone procedures. This work leverages our previous work on the definition of RDL, a language to facilitate the description of instantiation process, and describe the ReuseTool, which is an extensible tool to execute RDL programs and assist framework reuse by manipulating UML Diagrams. The ReuseTool integrates a RDL Compiler and a Workflow Engine to control most of the activities required to extend a framework design and, therefore, incorporates application-specific needs. This work also describes how the tool can be extended to incorporate new reuse activities and provides information of its use based on an exploratory Case Study. (C) 2011 Elsevier Inc.

SALESPOINT: A Java framework for teaching object-oriented software development

Teaching systematic object-oriented software development to undergraduate students is difficult: Students need to develop a lot of complex skills. These include technical skills in object-oriented software development, but also social skills for example, how to collaborate with other developers as part of a team working towards a large and complex software system. To acquire these skills, students need hands-on development experiences for example, through team-oriented project courses. Designing such project courses is a challenge in itself: They must be both sufficiently challenging and achievable within the limited time available. In our special situation (large numbers of students supervised by small numbers of staff) an important further requirement is scalability: Different projects should be easily comparable while allowing for different tasks for different teams to reduce the risk of plagiarism. The solution that in our experience satisfies all these requirements is to use an application framework for an everyday application domain for example, the business domain. Since 1997, we have been using SALESPOINT, a Java-based framework for creating business applications, that has been jointly developed and maintained in Dresden and Munich. In this paper, we briefly recollect the educational background and aims of the courses and present in some detail SALESPoINT (and its most recent revision, SALESPOINT2010): central notions like catalogs and stocks, the functionality it offers to users (application control, data management, and much more), a technical overview of its architecture, an example application built with SALESPOINT, and some lessons learned so far.

During the last two decades, software development has evolved continuously into an engineering discipline with systematic use of methods and tools to model and implement software. For example, object-oriented analysis and design is structuring software models according to real-life objects of the problem domain and their relations. However, the industrial robotics domain is still dominated by old-style, imperative robot programming languages, making software development difficult and expensive. For this reason, we introduce the object-oriented Robotics Application Programming Interface (Robotics API) for developing software for industrial robotic applications. The Robotics API offers an abstract, extensible domain model and provides common functionality, which can be easily used by application developers. The advantages of the Robotics API are illustrated with an application example.

With the success of Internet-based business, there is more and more interest in the availability of systems. Availability indicates that a system continuously provides a useful service at any given time. Failure detection and recovery methods are supported for developing application of availability. Requirement on availability may vary with applications and in addition may change over time. For applications to be independent of the change of availability requirement there should be a flexible and extensible architecture for supporting availability management. This paper presents an availability management framework (AMF), which supports the flexible management of availability for large distributed systems using object-oriented framework technologies. We focus on the AMF's flexibility in order to accommodate changing availability requirements which vary with each application. In addition, this paper describes the result of application of the framework to support availability of RFID systems.
