TL;DR: A framework for presenting standards, backed up by case studies of successful projects, is the solution proposed to provide better information on where particular BIM standards and solutions should be applied in building projects.

TL;DR: This paper focus on the presentation of different applications of GENE_ARCH, an evolution-based GDS aimed at helping architects to achieve energy-efficient and sustainable architectural solutions.

TL;DR: The research demonstrated that it is possible to transfer high level of geometric and semantic information acquired from BIMs into the geospatial environment and demonstrated that B IMs provide a sufficient level and amount of data management tasks in the site selection and fire response management processes.

TL;DR: Two new methodologies for model-free data interpretation to identify and localize anomalous behavior in civil engineering structures are presented and can effectively identify anomalous behaviors without explicit knowledge of structural characteristics such as geometry and models of behavior.

TL;DR: A comparative study of two machine learning methods on Arabic text categorization using the full word features and considered the tf.idf as the weighting method for feature selection, and CHI statistics as a ranking metric showed that both methods were of superior performance on the test corpus.

TL;DR: A combined method, consisting of an automated activity tracking subsystem based on image recognition, an automated material tracking subsystem, and a mobile computing supported communication environment, based on the same 4D model of a building is presented.

TL;DR: F fuzzy logic, genetic algorithms and artificial neural networks, as well as their fusion are reviewed in order to examine the capability of soft computing methods and techniques to effectively address various hard-to-solve design tasks and issues.

TL;DR: It is shown that this approach will require the design of some very sophisticated genetic coding mechanisms in order to develop the required higher-order network structures, and will utilize development mechanisms observed in nature such as growth, self-organization, and multi-stage objective functions.

TL;DR: The vision for data management and mining addressing challenges in data preparation, representation, and analysis is presented, together with related research results from previous work, as well as the recent developments of data mining on text-based, web-Based, image- based, and network-based construction databases.

TL;DR: This paper takes a practical approach to clarifying what ontologies are and how they might be useful in an important and representative phase of the engineering design process, that of design requirement development and capture.

TL;DR: The results show that the time-varying extended logistic model fits short product lifecycle datasets 70% better than the simple logistic and the Gompertz models and is better suited to predict market capacity with limited historical data as is typically the case for short lifecycle products.

TL;DR: It is proved that, from among the theoretically infinite number of feasible designs forming the Pareto front for a design problem governed by n independent objective criteria, there exists a unique Pare to-compromise design that represents a mutually agreeable tradeoff between all n criteria.

TL;DR: This paper presents a reusable, general-purpose, mobile augmented reality (AR) framework developed to address the critical and repetitive challenges specific to visualization in outdoor AR.

TL;DR: The study shows that the VR models in both projects have been very useful and well accepted by the users.

TL;DR: FAHP's connection to SWOT yields a novel hybrid method for partitioning of MTO/MTS products, and the proposed fuzzy AHP-SWOT methodology is validated through a real case study.

TL;DR: A promising service to use web-based extended manufacturing resources for product development and a case study of mould product development are presented, which promotes the networked collaborative design and manufacturing processes.

TL;DR: Results show that the proposed VEPGA outperforms the sequential reduction procedure (SRP) and PGA, and the combined performance index makes an excellent compromise between the linear independence aimed index and the modal energy aimed index.

TL;DR: A geometric modeling framework for facilitating the engineers' interactions with architectural models in order to detect potential structural problems, uncover opportunities, respect constraints, and ultimately synthesize structural solutions interactively with architectural Models is presented.

TL;DR: Unlike other materials selection methods, the presented method does not require derivation of material indices, extraction of ''if...then...'' rules, or cumbersome inference calculations, and uses widely available material property charts as material-relevant information.

TL;DR: This work presents a complementary solution based on the use of lightweight file formats to preserve specific aspects of the product data, in conjunction with a registry of relevant representation information as defined by the Open Archival Information System Reference Model.

TL;DR: MCSketcher is presented, a system that enables face-to-face collaborative design based on sketches using handheld devices equipped for spontaneous wireless peer- to-peer networking, especially targeted for supporting preliminary, in-the-field work.

TL;DR: This paper proposes a multi-model driven collaborative development platform for service-oriented e-Business systems that provides engineers/consultants with three views to support service- oriented software engineering, top-down business design and bottom-up service composite and development.

TL;DR: An approach for the modelling of manufacturing requirements, supporting both knowledge execution and information management, in systems for automated variant design is introduced.

TL;DR: It is argued that the information technology can be effectively used for providing an excellent opportunity for the professionals to learn from similar past projects and to better control project variations.

TL;DR: A unified formulation capable of systematically generating the governing symbolic equations for multibody, multi-domain systems based on the principle of orthogonality, a powerful concept that serves as a generalization of the principles of virtual work and virtual power.

TL;DR: This work considers a complex adaptive system as a model for the development of design representations, and presents a semi-constructive algebraic formalism for design representation, termed sorts, as a candidate for supporting this approach.

TL;DR: A novel compression scheme based on Boolean minimization of binary data accompanied with the adoption of Burrows-Wheeler transformation (BWT) algorithm for small text files is suggested.

TL;DR: Two different PDM systems are interfaced based on the PLM Services standard of OMG (www.omg.org), which is itself based on Web Services that enables the data exchange via the Internet.

TL;DR: A decentralized trust model to enhance reliable information dissemination in large-scale disasters is presented and includes a distributed recommendation scheme, incorporated into an existing membership maintenance service for ad-hoc networks and a nature-inspired activation spreading mechanism that allows trust-based information propagation.

TL;DR: This paper proposes a method for retrieving CAD models of mechanical parts by freehand sketches by combining the two similarity degrees measured by 2D outlines or skeleton into a unified one.
