The ensemble of regular Low-Density Parity-Check (LDPC) codes introduced by Gallager is considered. Using probabilistic arguments a lower bound on the normalized minimum distance is derived. A new code construction, called Chained Gallager codes, is introduced as the combination of two Gallager codes and its error correcting capabilities are studied.
Background: Despite the fact that old people´s technological needs have been payed much attention to in the last decennium, especially old users of information- and communication technology, technology has not found its natural place in research on ageing in modern societies. Purpose: This article examines to what extent social science research exist in the field of ageing and technology and where

A short range FM transmitter is presented. It uses an architecture where the output frequency of a phase locked loop (PLL) is modulated by varying the division number of the feedback divider, using the 1-bit output of a ΔΣ ADC. The measured total harmonic distortion (THD) plus noise is less than 1% at 75 kHz deviation. The transmitter is fully integrated in a 0.13µm CMOS process and the core area

Popular Abstract in English This book investigates marketing work in professional service organizations from a rhetorical perspective. It comes to the conclusion that this work is accomplished by self-reflexive marketers who are reminiscent of the ancient sophists – a diverse group of itinerant advisors whom came to Athens around the fourth century BCE for business reasons. Marketers travel – as dMarketing has traditionally been understood from the perspective of marketing management. This causes problems when we study marketing practices because the normative discourse of marketing management is not particularly useful for describing the day-to-day work of marketing practitioners. This calls for marketing research from new perspectives. Rhetorical business – A study of marketing work in t
