While low-density parity-check (LDPC) convolutional codes tend to significantly outperform LDPC block codes with the same processor complexity, large storage requirements and a long initial decoding delay are two issues related to their continuous pipeline decoding architecture [A. Jimenez Feltstrom et al., (1999)]. In this paper, we propose reduced complexity decoding strategies to lessen the sto

This conference paper discusses the artist Zarah Leander as a gay icon and queer diva.

This paper includes a brief description of some closely related ongoing research activities aiming at learning from failures in order to improve the resilience of the Swedish railway system. One of these activities includes the development of a method aiming at assessing the capability for restoring the service of the railway system after strains affecting its technical, and often highly interdepe

This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically. Also the workings of space astrome

Knowledge may be treated analogous to evolutionary processes. This view of knowledge has certain advantages compared to more traditional views. In particular, it allows the knowledge to be extended without the involvement of a separate agent. This means, in turn, that the problem of knowledge acquisition, known as Meno’s dilemma, is avoided. The purpose of this paper is to discuss how an evolution

Clinical and physical assessments of image quality are compared and the correlation between the two derived. Clinical assessment has been made by a group of expert radiologists who evaluated the fulfillment of the European Image Criteria for chest and lumbar spine radiography; yielding the so-called Image Criteria Score, ICS. Physical measures of image quality were calculated using a Monte Carlo m

Large-scale software development generates an ever-growing amount of information. Multiple research groups have proposed using approaches from the domain of information retrieval (IR) to recover traceability. Several enhancement strategies have been initially explored using the laboratory model of IR evaluation for performance assessment. We conducted a pilot experiment using printed candidate lis
