Abstract. Studies of the global sea-level budget (SLB) and ocean-mass (OMB) are essential to assess reliability our knowledge change its contributors. Here we present datasets for times series SLB OMB elements developed in framework ESA's Climate Change Initiative. We use these simultaneously, utilising a consistent uncertainty characterisation. The time series, given at monthly sampling availa...
The purpose of assurance activities is to reduce risk, thereby ensuring requirements. However, assurance activities incur costs such as budget, schedule, mass ( e g , radiation shielding), etc. The selection of assurance activities to perform is thus an assurance optimization problem. For example, for a given budget, selection of the set of assurance activities that will minimize risk (i.e., ma...
This article describes a primary calibration setup, and its uncertainty, for low flow liquid calibrations at Bronkhorst High-Tech. It will be used to calibrate reference flow meters from 1 to 200 g/h. By setting up an uncertainty budget for this setup, the calibration of the instruments can be compared to that of NMI’s (National Metrology Institutes). The uncertainty budget consists of mass, ti...
Glaciers distinct from the Greenland and Antarctic Ice Sheets are losing large amounts of water to the world's oceans. However, estimates of their contribution to sea level rise disagree. We provide a consensus estimate by standardizing existing, and creating new, mass-budget estimates from satellite gravimetry and altimetry and from local glaciological records. In many regions, local measureme...
In this paper, we use the general theory worked out within the past few years for the structure and the evolution of low-mass stars to derive the stellar mass-function in the Galactic disk down to the vicinity of the hydrogen-burning limit, from the observed nearby luminosity functions. The accuracy of the mass-magnitude relationships derived from the afore-mentioned theory is examined by compa...
The Dynamic Energy Budget (DEB) theory has become a fundamental tool in modeling the metabolic behaviour of organisms. Its capacity to describe the biological aspect of life alone justifies its applicability in Artificial Life. Aware of this potential, the DEB research group in Instituto Superior Técnico (IST) in Lisbon has joined the videogame company Biodroid Entertainment in the Life Engine ...
