The Circularity Calculator: A tool for circular product development with Circularity and potential value capture indicators

Most products require a redesign to be viable in a circular economy. For instance, by implementing design for disassembly, remanufacturing, recyclability, and using long-lived components. Typically, different solutions can be chosen to improve a products' circularity, and different strategies can be aimed at keeping the product, its components,...

A Review of Reviews on Computational Thinking Assessment in Higher Education

There is an urgent need for educating the next generation of learners with digital tools and making use of digital practices and skills. Education on computational thinking (CT) is widespread around the world with a dominant focus on K- 12. Recently also higher education has come more to the focus of CTE. However, most of the work on CT in...

Decay Patterns And Damage Processes Of Historic Concrete: A Survey In The Netherlands

Historic concrete buildings (end of 19th century – 1960s), because of their “experimental” character, require a specific approach to both survey and conservation. Although they were built with empirical approaches, some buildings show a fair state of conservation and resilience –even though they have already exceeded the 100-year threshold–...

Capacity of prestressed concrete bridge decks under fatigue loading

In The Netherlands, existing slab-between-girder bridges with prestressed girders and thin transversely prestressed concrete decks require assessment. The punching capacity was studied in a previous series of experiments, showing a higher capacity thanks to compressive membrane action in the deck. Then, concerns were raised with regard to...

Assessment Method for Spatial Planning and Infrastructure Development

In Europe, different road authorities have to face the ever increasing pressure to integrate their road network service provision with - often conflicting - different trends and conditions such as congestion, climate change, individualism, urbanization, safety, environmental issues and economic growth. There is also a need to cooperate with...

Improvements of a Nonlinear Analysis Guideline for the Re-examination of Existing Urban Concrete Structures

The Dutch Ministry of Infrastructure and the Environment is concerned with the safety of existing infrastructure and expected re-analysis of a large number of bridges and viaducts. Nonlinear finite element analysis can provide a tool to assess safety; a more realistic estimation of the existing safety can be obtained. <br/>Dutch Guidelines,...

Bayesian oma of offshore rock lighthouses: Surprises with close modes, symmetry and alignment

A set of seven rock lighthouses around the British Isles was studied by a combination of forced and ambient vibration tests executed with some extreme logistical constraints. Forced vibration testing of the circular section masonry towers combined with experimental modal analysis identified modes with alignment assumed the same as the shaker...

Strategies for Assessment in Materials Science and Engineering MOOCs: Short-Answer Grading Best Practices

Developing meaningful educational assessments in massive open online courses can be a significant challenge for course developers. In this report, we discuss a variety of strategies that we have used in Materials Science and Engineering MOOC development in order to assure that we are giving our students meaningful and rigorous assessment...

[POSTER] ChiroChroma: An Augmented Reality Game for the Assessment of Hand Motor Functionality

For a better understanding of how different diseases (e.g. neurovascular diseases, neurodegenerative diseases, and musculoskeletal pain conditions) affect human motor function, a uniform, standardized and objective evaluation is a desirable goal expressed within the clinical community. We explore the capabilities of an augmented reality (AR)...

Towards Engaging Upper Extremity Motor Dysfunction Assessment Using Augmented Reality Games

Advances in technology offer new opportunities for a better understanding of how different disorders affect motor function. Our aim is to explore the potential of augmented reality (AR) using free hand and body tracking to develop engaging games for a uniform, cost-effective and objective evaluation of upper extremity motor dysfunction in...

Negotiating heritage in danish public housing renovation

This paper presents a significant problem when it comes to the challenging task of safeguarding recentpast architectural heritage with reference to the democratization ideals propagated by the New Heritage paradigm. Based on controversy mapping relating to the renovation of a Danish 1950s high-rise complex of public housing, it discusses how...

Organizational and cultural assessment of GIIs: The introduction of a new model

A geographic information infrastructure (GII) develops gradually. Several development stages may be identified each with unique characteristics. Also the organisational characteristics are likely to vary per stage. This knowledge was used to develop an SDI maturity matrix as presented by Kok and Van Loenen (2005), further developed in Van Loenen...
