Digital Subscriber Lines (DSL) are today one of the most important means for delivering high-speed data transmission. Dynamic Spectrum Management (DSM) is an emerging technique for dealing with crosstalk, one of the technology's most harmful problems. DSM judiciously designs users' power spectral densities so that the overall system performance is improved. This works aims at presenting a new insi
The known methods for designing nonmagnetic absorbers usually aim for either the reduction of total thickness or increase of absorption bandwidth by sacrificing the other parameter. The conventional circuit analog absorbers aim for large bandwidths whereas the newly proposed meta-material or optimized geometry designs try to reduce the thickness of the absorber. By the aid of the capacitive circui
In this paper it is argued that it is legitimate to talk about mental imagery, and thus, to claim that spatial information is coded in an analogue mode. Evidence from research with blind people indicate that they can perform mental rotation and that analogue spatial cognition does not depend on visual information. It is therefore proposed that, if the blind can perform mental rotation in an analog
Ligands for the benzodiazepine-binding site of the GABAA receptor can belong to structurally diverse classes of compounds including, in spite of the name of the binding site, many non-benzodiazepine structures. The GABAA receptor is a ligand-gated ion channel assembled of five subunits from eight different classes with multiple isoforms. The physiological effect elicited by benzodiazepines is beli
External involute helical gears are usually manufactured through hobbing, commonly with a subsequent grinding or skiving operation. One way towards the industrial pursuit of more competitive and sustainable manufacturing is to reduce the number of processes, while retaining functionality and quality. In the hobbing of gears, the manufacturing errors are most often connected to the tool and/or the
