Global Governance of Biofuels for Transport: Viewpoints of Key Stakeholders?

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

Learning characteristic decision trees

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

Construction of a FrameNet Labeler for Swedish Text

We describe the implementation of a FrameNet-based semantic role labeling system for Swedish text. To train the system, we used a semantically annotated corpus that was produced by projection across parallel corpora. As part of the system, we developed two frame element bracketing algorithms that are suitable when no robust constituent parsers are available. Apart from being the first such system

Enhancing Multisensory Environments with Design Artifacts for Tangible Interaction

Even though multisensory environments (MSE) incorporate artifacts and technology to provide sensory stimuli, most of these artifacts are non-interactive. Twenty-four children with profound developmental disabilities from three MSE institutions have been involved in a research study. A handful of interactive design artifacts, which have been developed as a tool for ideation and to enhance the use o

1/f Noise Characterization in CMOS Transistors in 0.13um Technology

Low-frequency noise has been studied on a set of n- and p-channel CMOS transistors fabricated in a 0.13mum technology. Noise measurements have been performed on transistors with different gate lengths operating under wide bias conditions, ranging from weak to strong inversion. Noise origin has been identified for both type of devices, and the oxide trap density Nt, the Hooge parameter alphaH and t

Beam loss mechanisms in relativistic heavy-ion colliders

The Large Hadron Collider (LHC), the largest particle accelerator ever built, is presently under commissioning at the European Organization for Nuclear Research (CERN). It will collide beams of protons, and later Pb ions, at ultrarelativistic energies. Because of its unprecedented energy, the operation of the LHC with heavy ions will present beam physics challenges not encountered in previous coll
