We evaluate the performance of list sequence (LS) maximum a posteriori probability (MAP) decoding on the additive white Gaussian noise (AWGN) channel and the fully interleaved flat Rayleigh fading channel. In particular, we focus on the frame error rate (FER) of LS-MAP decoding with genie-assisted error detection. It is demonstrated that LS-MAP decoding yields significant performance improvements
The article examines specimens from five Latin sermon collections that were widely used as models for sermon composition in the later Middle Ages. Four of the collections were studied in incunable editions. One of the results is that the only day of the eclesiastical year on which one finds a more or less regular discussion of the Last Judgement is the first or second Sunday of Advent. The subject
Migration is a common phenomenon in many organisms, terrestrial as well as aquatic, and considerable effort has been spent to understand the evolution of migratory behaviour and its consequences for population and community dynamics. In aquatic systems, studies on migration have mainly been focused on commercially important fish species, such as salmon and trout. However, seasonal mass-migrations
This paper discusses the potential for personalized, user-owned decision-support systems. It can be readily seen that there are benefits from analysis of ‘Big Data’ that could not be attained through more traditional means, e.g. insurance and credit card fraud can be detected more readily when it is possible to analyze integrated data across multiple servers owned and controlled by separate organi
Ansökningstalen för Elektroteknikprogrammet, LTH, har sedan IT-kraschen 2000 minskat kraftigt. Detta fenomen är inte unikt för Lund utan kan noteras på Sveriges övriga tekniska högskolor och internationellt i västvärlden. De programansvariga har under flera år varit medvetna om problemen och har på bred front försökt att möta de nya förutsättningarna och vända trenden. Färsk statistik visar att vå
The MAX IV facility presently under construction will include two storage rings for the production of synchrotron radiation. The 3 GeV ring will house insertion devices for the production of x-rays while the 1.5 GeV ring will serve UV and IR users. Both rings will be operated at a constant 500 mA of stored current with top-up shots supplied by the 3.5 GeV MAX IV linac acting as a full-energy injec
Would slightly better performance be significantly more valuable from a market perspective? Would significantly better performance be just slightly more expensive to implement? When dealing with quality requirements, we often end up in a difficult trade-off analysis. Aspects such as release targets, end-user experience, and business opportunities must be taken into consideration. But when is the q
Polisforskare talar idag om ”den utökade polisfamiljen”. Den traditionella polisen kompletteras av kommunala, privata och frivilliga organisationer eller grupperingar. Samtidigt står etniska minoriteter alltmer i centrum för samhällets kontrollapparat. Etnicitet har blivit en delikat fråga för myndigheter. Den här antologin uppmärksammar skärningspunkten mellan dessa två processer. På vilka sätt
A full century ago, H. G. Wells said that a hand seemed to have descended from the sky and turned man’s face towards the future. Wells wrote in an era which saw a new world appear through the progress of technology. Today we may be just as attracted to new technology, but that great hand seems to have come down again and turned man’s head back towards the past. Our own time is characterized by an
A biographival entry on Professor Axel Moberg, a famous Swedish Syriac scholar who was professor of Near-Eastern languages at Lund University, Sweden, 1908-1937, and Vice Chancellor of the same university, 1926-1936.
