We investigate the bandwidth and distance of codes created by ordinary lowpass filtering of a pulse stream. The encoder is thus a convolution, but over the reals. Performance of these codes is compared to the TCM and PRS code families; despite their simplicity, the new codes perform equally well. Since a simple decoder exists, these are attractive codes.
Changes in evolving software systems are often managed using an issue repository. This repository may contribute to information overload in an organization, but it may also help navigating the software system. Software developers spend much effort on issue triage, a task in which the mere number of issue reports becomes a significant challenge. One specific difficulty is to determine whether a new
The political objectives on national and international levels towards a larger proportion of renewable energy require considerable planning activities on a local level. These activities inevitably must relate to the local community and its various groups; their culture, economy, social activities as well as their views on environmental problems and nature values. This applies to all energy plants.
A flexible channel decoding platform should be able to operate in varying communication scenarios, and different code rates have to be supported. Therefore, we present a framework that allows efficient processing of rate-flexible trellises. Using a fundamental computational unit for trellis-based decoding, formal principles are obtained to emulate more complex trellises. In a design example, such
Popular Abstract in Swedish Avsikten med denna avhandling är att förstå de viktiga begreppsmässiga och operativa utmaningar som internationella biståndsgivare, liksom offentliga och privata institutioner, möter när man utformar och genomför alternativa former av sociala bostadsfinansiering som skall vara inkluderande för den fattiga urbana befolkningen. Avhandllingen försöker besvara tre frågor, bThe purpose of the thesis is to further understand key conceptual and operational challenges that international aid donors, and public and private institutions, face while designing and implementing alternative forms of social housing finance which aim to be inclusive for the urban poor. Based on an in-depth study of the work of the Foundation for the Promotion of Local Development (PRODEL) in thr
There is an increased interest in and awareness of mould growth damage in buildings. Today’s mould growth models are limited to only presenting the risk of mould growth. They do not take into account underlying factors and other parameters that make it possible to establish necessary measures to limit or avoid the risk of mould growth. This paper presents a chart that can be used to determine thes
Abstract in ItalianThe study presented here is part of a wider context of historical ecology and rural archaeology research projects carried out by the Laboratorio di Archeologia e Storia Ambientale (LASA, Dafist-Distav) of Genoa University. In particular, our contribution is focused on the reconstruction of agricultural practices connected to the historical transformation of breeding systems in t
Calreticulin is a multifunctional protein mainly localized in the endoplasmic reticulum in eukaryotic organisms, except yeasts. The protein comprises three distinct regions: the N-terminal N domain, the C-terminal C domain, and the central P domain, reflecting the functional diversity of calreticulin. The protein has been implicated in over 40 intra- and extracellular processes in mammalian cells,
Gråborg i Algutsrums socken är en av de mest välkända fornborgarna på Öland. Mellan åren 1999 och 2002 har flera mindre forskningsundersökningar utförts av Gråborg och under 1998 genomfördes en undersökning av S:t Knuts kapellruin. En viktig fråga har varit att datera de olika lämningarna, men även att belysa en rad andra viktiga frågor. Här utgör keramikmaterialet en av de mer betydelsefulla käll
This thesis describes a series of studies designed to elucidate brain circuitry changes during parr-smolt transformation (smoltification) in salmon. The studies revealed sequential orderly chemical and structural changes of the brain. The first study showed sequential changes in concentration of mu-and kappa-opiate receptors in select cell groups of the brain during various stages of smoltificatio
Very little radical or really new innovation within the food sector in Sweden is visible today, although the stores are jammed with food in a variety of packages, designs and sizes and under different brands. Most products appear to be based on technologies introduced years ago, and the diversification consists mainly of line extensions, i.e. incremental development. It looked different after the
