Open standard CMO for parametric modelling based on semantic web

The Open Standard Concept Modelling Ontology (CMO) with Extensions makes it possible to store parametric modelling semantics and parametric geometry in a Semantic Web environment. The parametric and geometrical part of CMO with Extensions is developed within the EU project Proficient. The nature of the Semantic Web with support for multiple...

BIM on the construction site: Generating on demand, task specific drawings in the site office

Building Information Modeling is accepted as the new technology for design, engineering and collaboration AEC projects. There is a group of people that has specific needs on the BIM data: the construction workers. At this moment drawings are created from a BIM model at a specific moment in the whole building process. The information on the...

Interoperable tools for designing energy-efficient buildings in healthcare districts

The EU funded collaborative research project STREAMER aims on Energy-efficient Buildings (EeB), focusing on mixed-use healthcare districts. Besides innovations in EeB technology, special emphasis is laid on improving methodologies and tools used in the design process of new or retrofitted hospital buildings. STREAMER follows a model-based,...

Hospital campus design related with EeB challenges

Energy efficiency and reduction of carbon emission of Healthcare buildings and districts are a key factor for a sustainable community since their energy use and carbon emission are among the highest of all building types. A hospital - which is a part of a healthcare district - uses 2.5 times more energy than an office in average. In order to...

Performance engineering for industrial embedded data-processing systems

Performance is a key aspect of many embedded systems, embedded data processing systems in particular. System performance can typically only be measured in the later stages of system development. To avoid expensive re-work in the final stages of development, it is essential to have accurate performance estimations in the early stages. For this...

DSEEP Process authoring made easy

The Distributed Simulation Engineering and Execution Process (DSEEP) is a recommended practice for the development and execution of a distributed simulation environment, and provides a general process model that is meant to be tailored to meet the needs of individual applications. In 2011 DSEEP was released as a new standard: IEEE 1730-2010....

Stochastic uncertainties and sensitivities of a regional-scale transport model of nitrate in groundwater

Groundwater quality management relies more and more on models in recent years. These models are used to predict the risk of groundwater contamination for various land uses. This paper presents an assessment of uncertainties and sensitivities to input parameters for a regional model. The model had been set up to improve and facilitate the...

Elimination of flow-induced pulsations and vibrations in a process installation: a combination of on site measurements, calculations and scale modeling

The aim of the work described in this paper was to trace and eliminate vibration sources in a low pressure system with high flow velocities. Considerable vibration on the pipe system between a flashing vessel (6.5 m diameter) and heat-exchangers resulted in fatigue failure, leakage and subsequent shut down of a chemical production plant. As...

ERGOtool for the integral improvement of ergonomics and process flow in assembly

Manufacturers of manually assembled products are increasingly being forced to improve the flow of assembly orders, together with having more efficient employment, in order to meet increasing demands on short delivery times, high product variety, good quality and low manufacturing costs. At the same time, the human factor is increasingly...

Use of fluid curtains for post-release mitigation of gas dispersion

The European Process Safety Centre is an industry-funded organization which exists to provide an independent technical focus for process safety in Europe. The centre has four main objectives: information; research and development; legislation and regulations; education and training. In pursuit of the R&D objective EPSC has contracted the...

Feasibility of energy efficient steam drying of paper and textile including process integration

This article deals with a feasibility study on superheated steam drying of paper and textile. Drying with superheated steam in direct contact with the paper or textile web offers great advantages over conventional ways of drying with respect to energy efficiency, drying rate and quality aspects. The evaporated water in this drying process comes...
