We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles. Finally, we evaluate the bit error rate perform

This report focuses on critical metals in Waste from Electrical Electronic Equipment (WEEE) and their recycling possibilities. The criticality is defined in terms of demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy. The report covers assessments of (1) the potential amount of critical metals in the selected product groups, and (2) the actual
Moisture is decisive for a large number of reaction, binding and transport processes in concrete affecting the durability, shrinkage and performance in various environments. Consequently, the role of moisture must be assessed and quantified in a diagnosis of concrete degradation by moisture measurements and a survey of environmental actions. The paper gives an over-view of the role of moisture in
Popular Abstract in Swedish Under det senaste decenniet har idén om maximering av aktieägarvärde (Shareholder Value) och en allmänt ökad aktiemarknadsorientering spridit sig från USA och Storbritannien, där den traditionellt har haft ett starkt fäste, till övriga Europa och utgör numera en dominerade ideologi i många av de större, börsnoterade aktiebolagen. Mycket av den traditionella litteraturenDuring the last few decades, the belief in the economic benefits of maximization of shareholder value as a principle of corporate governance has spread from its traditional Anglo Saxon strongholds to the rest of Europe and can now be described as an established and dominant ideology in many large corporations. The more influential part of the literature on shareholder value has mainly paid attenti
Abstract in Danish Territorier, stater og nationer har stadig stor betydning. Selvom Europa på overfladen kan se ud som en overskuelig politisk geografi af suveræne stater, er der i virkeligheden tale om et kompliceret kludetæppe af formelle og uformelle grænser og overlappende territorier. Nutidens Europa minder på mange måder om middelalderens komplicerede politiske geografi. Territorium, stat o
The emerging concept of cognitive radios offers a way to use the limited radio-spectrum more efficiently by allowing networks and nodes to adaptively vary their parameters. An important element in the successful implementation of cognitive radios is the ability to estimate the varying state of spectrum usage in a wide-band channel quickly and at minimum cost. In this work, we utilize a powerful no
The plutonic rocks in the Western Segment of the Southwestern Swedish Gneiss Complex show a distinct geochemical evolution. The 1.6 Ga Åmål granitoids and Slottsbron migmatites are a quartz dioritic to granodioritic, calc-alkaline rock suite with smooth, but somewhat fractionated, REE and other trace-element patterns. The younger microcline granites of the 1.5 Ga and 1.3 Ga generations are evolved
Popular Abstract in Swedish I mitt arbete som neuropsykolog vid minnesmottagningen på psykogeriatriska kli¬niken (numera VO kognitiv medicin) vid Universitetssjukhuset i Lund har jag träffat många patienter som beskrivit besvärande minnessvårigheter i sin vardag. Patienterna berättade om svårigheter att lära sig nya rutiner på arbetet, att komma ihåg namn eller var de hade lagt sina saker. Många aThe overall aim of this thesis was to enhance the understanding of patients with subjective memory complaints. The thesis is based on three empirical studies examining middle-aged and young old (< 70 years) non-demented patients assessed at a memory clinic. In the first study the personality characteristics of the patients were compared with a Swedish normative sample. The patients scored higher o
Popular Abstract in Swedish Proteiner är stora kedjelika molekyler som syntetiseras i cellen med utgångspunkt från arvsmassan, DNA. I alla organismer har proteinerna en mängd uppgifter som kan sträcka sig allt ifrån att vara byggnadsmaterial i senor och bindväv till att fungera som avancerade molekylära maskiner i organismens energiomsättning. I stor utsträckning reglerar olika proteiner också bilAbstract. This thesis describes factors that are rate limiting for the folding of two small proteins, U1A and CI2 which fold without accumulating intermediates. The [GdnHCl] dependencies of the unfolding- and refolding kinetics of U1A display downward curvatures. However, as the curvatures are precisely matched and no indications of formation of partially structured intermediates are seen, the fol
