Most offshore wind farms are bottom-fixed at sites with less than 50 m of water depth. For deeper waters, floating platforms economically viable and, for many countries that have steep continental shelves, this is the only option developing farms. If energy being harvested far in deep waters (more 200 depth and hundreds km from coast), one possible alternative use Floating Production Storage (F...

Non-square process control systems, with fewer inputs than the controlled outputs, are quite common in chemical processes. In these systems, it is impossible to control all measured variables at specific set points and many of the outputs are controlled within an interval. The objective of this paper is to introduce a multivariable Operability methodology for such non-square systems to be used ...

The operability of a vessel in the sea environment, i.e. the capability to accomplish its mission is a major performance indicator of the vessel. It is well known that adverse sea conditions induce significant dynamic motions, velocities, accelerations and loads, which deteriorate the performance of both the crew and the various subsystems onboard, including the hull form itself. For example, t...

One of the most serious threats to the development of the learning object economy as described by Downes (2002) is the consistent campaign by the controllers of copyright to undermine, and render inoperable, the public domain. The learning object economy is the system of learning object repositories, distribution systems and rights’ management that is currently being developed by a wide variety...

The ‘fit’ of a garment is often considered to be a subjective measure of garment quality. However, some experts attest that a complaint of poor garment fit is a symptom of inadequate or excessive ease, the space between the garment and the wearer. Fit has traditionally been hard to quantify, and space suits are an extreme example, where fit is difficult to measure but crucial for safety and ope...

In this paper we present conflict resolution measures in connection dispatching suitable for railway transportation companies without having full access to relevant data. The presented measures do not only cover classical waiting/non-waiting-strategies but also alternative dispatching measures if a distributor train cannot wait. The fact of unknown travel chains and insufficient data availabili...
