To evaluate the 5-year course of physical work capacity of participants with early symptomatic osteoarthritis (OA) of the hip and/or the knee; to identify trajectories and explore the relationship between trajectories and covariates. Methods In a prospective cohort study, physical work capacity was measured …

To analyze on-water rowing performance, a valid determination of the power loss due to the generation of propulsion is required. This power los can be calculated as the dot product of the net water force vector ( ~ F w;o ) and the time derivative of the position vector of the point at the blade where …

This paper presents the results of a study regarding the cyclic bending over sheave fatigue life of five different type of small diameter cables (d <=2.5 mm) in a simple bending test around a D = 10 mm sheave. The goal of the study is to estimate the lifespan of cables in prosthetic applications. Three …

When a pipeline is laid on the seabed it can be exposed to hazards of ship anchors, large fishing gear or ice keels. To prevent the pipeline of being damaged, the pipeline can be trenched. Trenching is a technique where the pipeline will be buried in the seabed to a certain depth. This can either be …

When considering a composite strip or plate under certain thermal and environmental conditions and loadings, there is a minimum strain threshold for the appearance of the first micro crack. The associated strain level is defined here as “critical strain”. There are various active displacement methods …

Barges are used in order to transport all types of offshore structures and equipment. Structures which are transported are becoming larger and heavier. Therefore, there is need for barges that can handle these structures. This research will explore the possibilities to increase barge capacity by adding …

One could write an alternative history of the Western modern arts as a struggle with industrialization. In this history, there would be almost no connection between classical fine art painting to the modern arts, but it would start with medieval craftsmanship, continue with the Arts & Crafts movement …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …

How far can we go with a lightweight structure that consists of almost weightless twigs? At what point does wicker need support from an additional structure? And how can we scale up a traditional technique, which is usually related to basket weaving and small objects, to the scale of architecture? These …
