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

Significant faunal changes reported fromrecent, coastal environments,which are not directly influenced by urban and industrial impact, are rarely seen. In Gullmar Fjord on the Swedish west coast, a significant foraminiferal fauna change occurred in connectionwith severe low-oxygen conditions that evolved in thewinter of 1979/1980. A foraminiferal fauna marked by common Skagerrak–Kattegat species,

Popular Abstract in Swedish Bakgrund En grundförutsättning för detta avhandlingsarbete var att smärta i rörelseapparaten kan studeras som ett samlat begrepp. Med två undantag, fibromyalgi och reumatoid artrit, avstod vi därför från att beskriva smärtan utifrån specifika diagnoser. Detta förhållningssätt har stöd i den mest vedertagna definitionen av smärta, som arbetats fram av IASP (InternationaThe aim was to study prevalence, assessment methods, and risk factors of chronic musculoskeletal pain, as well as effects on health status in a general population setting. A postal survey to a representative sample of 3928 subjects aged 20–74 years in 2 municipalities on the west coast of Sweden was followed by clinical examinations of selected subjects, and a three-year follow up survey to 2425

Analysts are often asked to help deliver systems that have a great mix of performance and features. Unfortunately, problematic organizational gender related issues have sometimes been degraded and treated as unrelated to technological issues. While ISD in general is trying to ensure support for businesses, we might in the future expect more than just a gender-ignorant quality-measure in the way th

A thin resistive sheet is described by its sheet conductance, and the electric and magnetic dipole moments per unit area. All three properties can be controlled by the material parameters and geometry of the sheet, for instance by making a periodic pattern of holes in it. A mathematical analysis of the low frequency limit of Maxwell's equations in a periodic setting generates a hierarchy of local

When a mobile station moves along a trajectory, it will see different parts of the same scatterers or scatterer groups during its movement. In this paper, we present a new method to identify such physical clusters of scatterers, and the corresponding groups of multipath components (MPCs) interacting with those clusters, from measurements of channel impulse responses. The method is based on identif

How are you supposed to define "The Baroque"? What does "Baroque literature" mean? In the frame of an encyclopedic article a reflection to this complex topic is given by highlighting the interplay of arts.
