Determination of the effectivity, usability and acceptance of an exoskeleton for a specific job requires a three-stage approach in which we get a first impression of its usefulness and potential fit (field observation), in which we measure the work load reducing effect (controlled experiment), and in which we measure use and acceptance,...

The supportive effect of arm-support exoskeletons has been mainly studied for single postures or movements. The aim of this study is to analyse the effect of such an exoskeleton on shoulder muscle activity and perceived exertion, in six tasks of plasterers, each including multiple arm movements. The tasks of ‘applying gypsum’, ‘screeding’ and ...

Urban mining from construction and demolition waste (CDW) is highly relevant for the circular economy ambitions of the European Union (EU). Given the large volumes involved, end-of-life (EoL) concrete is identified as one of the priority streams for CDW recycling in most EU countries, but it is currently largely downcycled or even landfilled....

Circularity is an increasingly often mentioned ambition of governments of various levels, yet the translation into concrete plans and policies is limited. The Metropole Region of Amsterdam (MRA) is a pioneer in this field, initiating a research for circular rebuilding of a neighbourhood in 2016 and the development of a roadmap for circular urban...

Background. The aim of this study is to develop a new measure for the concept of mental retirement and test the construct validity of the measure. Employees who are ‘mentally retired’ are present at their work physically, but have already said their goodbyes mentally. Mental retirement has a three-factor structure: developmental proactivity,...

Offshore asset construction is a complex and costly process that is subject to various uncertainties within the entire supply chain. Hence, both the construction management optimization and the reduction of deployment expenditures should be supported by automated decision support models which include proper representations of predominant...

We demonstrate in this geothermal exploration case study performed in The Netherlands that ambient noise seismic interferometry (ANSI) can be an effective and efficient method for obtaining surface wave dispersion curves, leading to shallow shear-wave velocity-depth profiles that can improve imaging of deep structures. As the ANSI method...

The increasing volume of Construction and demolition waste (CDW) associated with economic growth is posing challenges to the sustainable management of the built environment. The largest fraction of all the CDW generated in the member states of the European Union (EU) is End-of-life (EOL) concrete. The most widely applied method for EOL concrete...

Sound produced by marine pile driving activities poses a possible risk to marine life. The assessment and mitigation of this risk requires a precise prediction of the expected levels. An analytical approach to estimate the radiated sound exposure levels is presented, based on the axial symmetry of the problem, resulting in damped cylindrical...

Interaction of ultrasonic waves with partially-closed surface-breaking cracks in concrete structures has been studied. Measurements have been conducted on a reinforced concrete beam containing various mechanical-load-induced cracks and compared with the baseline measurements at those locations. Influence of crack width, incident angle of waves...

The Province of Zuid-Holland encourages the development of innovations to make the provincial road network more energy efficient. This is one way the province can contribute to reducing energy consumption and CO2 emissions in accordance with the Dutch energy agreement. To this end, the Province of Zuid-Holland, Strukton Civiel and TNO have...

Quality control during the construction process is one of the determining factors that governs the service life of an asphalt road. In CONSISTEND a predictive tool is developed that objectively determines the effect of quality control during the construction processes on the life span of surface courses of asphalt roads. The tool predicts the...

Background. Organisations spend a considerable amount of time and effort on diagnosing and analysing risks within their organisation. In the area of occupational and process safety, a myriad of employee survey instruments is available. Many studies show that operational processes play an important role in an organisations overall safety. Yet, so...

The underwater sound produced during construction of the Port of Rotterdam harbor extension (Maasvlakte 2) was measured, with emphasis on the contribution of the trailing suction hopper dredgers during their various activities: dredging, transport, and discharge of sediment. Measured source levels of the dredgers, estimated source levels of...

Objectives To validate the Labor and Delivery Index (LADY-X), a new delivery-specific utility measure. Study Design and Setting In a test–retest design, women were surveyed online, 6 to 8 weeks postpartum and again 1 to 2 weeks later. For reliability testing, we assessed the standard error of measurement (S.E.M.) and the intraclass correlation...
