Data integrity is commonly defined by a number of properties, which are summarized by the acronyms ALCOA and ALCOA+, respectively. Hence, ALCOA stands for «attributable», «legible», «contemporaneous», «original», and «accurate», while ALCOA+ extends these attributes by the properties «complete», «consistent», «enduring», and «available». The present white paper explains...
The use and potential of Big Data is increasing day by day, as is the debate about data ethics. The line between good use and misuse or abuse of data is very thin. Technology is not the problem, but how we use it and whether this use adheres to criteria of responsibility. Big Data has multiple uses that contribute to the development of our society in areas as diverse as ...
There are four skills that must be mastered by laser pipe cutting machines. When the traditional process is used to process holes, there will be depressions, inaccurate hole positions, and burrs. Now the finished products cut by laser pipe cutting machines are not only smooth and burr-free, but also have a hole diameter. The size can also be used flexibly, so as to meet ...

Degrees of freedom Some multi-axis systems can have six degrees of freedom and seven (or more) axes of motion. This article explains the difference between “axes of motion” and “degrees of freedom,” and why it matters. Cartesian versus polar coordinate systems In linear motion, we typically use the Cartesian coordinate system, but some applications — particularly thos...
In an Estonian brewery, beer is produced from yeast, hops, malt, and water. Delivered by trucks, the malt is stored in silos before further processing. When it is needed in production, the malt is being filled into big bags and transported to its place of use in the brewing process. During the filling, it might occur that big bags are not properly attached, or that they ...
Introduction A concrete reason for the Brabantse Delta Water Board to look for a solution to realize additional measurements of the surface water level is the more intensive monitoring of water level areas. At the moment there are still a large number of gauging sections where the water level can only be measured occasionally and manually. Based on the task of complying ...
