Abstract Additive manufacturing with steel opens up new possibilities for individual parts or complex supply chains. The direct energy deposition process DED-arc, also known as wire arc additive (WAAM), is particularly suited large structures a high degree of geometrical freedom. design freedom makes WAAM ideal creating force-flow-optimized nodes and spaceframes use in the construction industry...

Verification and validation are crucial software quality control procedures to follow when developing and implementing models. This is particularly important because a variety of stakeholders rely on accurate predictions from building simulation programs. This study uses the BEopt Automated Residential Simulation Test Suite (BARTS) to facilitate comparison of two energy simulation engines acros...

The objective of Subtask A (“Performance”) of IEA SHC Task 27 “Solar Façade Components” is to further develop, structure and integrate the energy performance assessment methodology for windows and other solar building envelope components. Such a methodology will facilitate selection of components and enable comparative performance to be made. Particular emphasis is given to the assembly and int...

are shaped, semantic modeling—what the building components are, and pattern modeling—how the building components are used by users. We conclude that a new extensible and pattern-embedded BIM system will be necessary to facilitate environment-behavior simulation.

Client computers are often a weak link in a technical network infrastructure. Increasing the security of client systems and applications against malicious software attacks increases the security of the network as a whole. Our work solves in tegrity and authenticity of input, confidentiality, integrity and authenticity of output. We present components to integrate a trusted path into an applicat...

Computer-Assisted Construction Planning (CACP) is under development in support of Total Project Systems (TOPS). CACP, as a prototype application, employs a Case-Based Reasoning (CBR) tool, to address the requirements of information retrieval and subsequent reuse for preliminary project planning. The unique aspects of CACP include: 1) a design with respect to an integrated construction managemen...

Despite the growing interest for component-based systems, few works tackle the question of the trust we can bring into a component. This paper presents a method and a tool for building trustable OO components. It is particularly adapted to a design-by-contract approach, where the specification is systematically derived into executable assertions (invariant properties, pre/postconditions of meth...

Mobile agents are a promising technology for developing applications in many application domains. However, it has not yet gained a large acceptance from the developers. One important reason for this is the difficulty of using generic mobile-agent platforms in specific application domains, which have very concrete requisites. In this paper, we present a reusable component-based framework that en...
