Parallel robots are generally said to be more accurate and have a smaller workspace compared to serial robots. With the Gantry-Tau robot, a parallel robot with relatively large workspace was presented. This article examines the end-effector positioning accuracy of the Gantry-Tau robot. End-effector positioning errors arising from joint positioning or modeling errors are studied. A geometric approa
In the context of the emerging bioeconomy, the production and use of biofuels for transport is expanding rapidly around the world. This development presents both exciting opportunities and significant risks. Not least because biofuels are intimately connected to (and impacting on) food, water, climate and economic systems. The implications of different production chains and the international trade
Decision trees constructed by ID3-like algorithms suffer from an inability of detecting instances of categories not present in the set of training examples, i.e., they are discriminative representations. Instead, such instances are assigned to one of the classes actually present in the training set, resulting in undesired misclassifications. Two methods of reducing this problem by learning charact
