Let us have an NLFSR with the feedback function g(x) and an LFSR with the generating polynomial f(x). The function g(x) is a Boolean function on the state of the NLFSR and the LFSR, at any time instance t. Whenever the LFSR has good statistical properties, it is used for controlling the randomness of the NLFSR's state machine. In this paper we define and study the general class of "Grain" family o
This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic. Conseque
Abstract in Undetermined In media, policymaking and research, increasing attention is drawn to the phenomenon of ‘green political consumerism’, referring to consumerrelated practices that are based on concerns beyond the traditional criteria of product quality and price. Political consumerism is about expressing non-economic values, that is, values beyond the direct, economic self-interest of cons
Popular Abstract in Swedish En central fråga av både teoretisk och praktisk betydelse är varför vissa företag är mer framgångsrika - vilket ofta uttrycks som att de har större konkurrensfördelar - än andra. Speciellt uppkommer frågan då vissa fabriker inom samma företag år efter år uppvisar ett bättre ekonomiskt resultat än andra. Fokus i denna avhandling är att förstå varför så sker inom ett utvaThe most central question in the strategic management literature is why some firms are more successful than others, often expressed as an aim to understand sources of competitive advantage. In this thesis, an empirical observation is made that a number of manufacturing plants belonging to the same firm show sustainable differences in financial success, and the question is why. The main theoretical
The paper discusses the key enabling mechanisms introduced by Web 2.0 technologies that can support Product Service Systems (PSSs) development teams in increasing the quality of early design decisions. The paper collects success stories and lessons learned from two empirical case studies in the aeronautical supply chain, and from a set of questionnaires forwarded to major automotive manufacturers,
Formulating and implementing a new strategy may be a challenging task, especially if it alters the way in which a company has operated and positioned itself before. This may be particularly true for companies within the forest industry, like manufacturers of paper packaging products, pursuing differentiated customer value and innovative solutions where, traditionally, success has been measured in
Solid waste became one of the major environmental problems in Jordan, which has been aggravated over the past 15 years by the sharp increase in the volume of waste generated as well as qualitative changes in its composition. The challenges face solid waste management (SWM) in Jordan are numerous. Financial constraints, shortage of proper equipment and limited availability of trained and skilled ma
End-tidal PCO2 (PET CO2 ) has been used to estimate arterial pressure CO2 (Pa CO2 ). However, the influence of blood temperature on the Pa CO2 has not been taken into account. Moreover, there is no equation validated to predict Pa CO2 during exercise in severe acute hypoxia. To develop a new equation to predict temperature-corrected Pa CO2 values during exercise in normoxia and severe acute hypoxi
Wilms' tumor (WT), the most common kidney tumor among children, is characterized by a triphasic morphology consisting of blastemal, epithelial, and stromal components. Adult WT is a rare malignancy displaying similar histological features. We here present the first published high-resolution genomic analysis of a mixed-type adult WT. This revealed a more pronounced genetic complexity than usually o
Coeliac disease (CD) is becoming a model for understanding the pathogenesis of autoimmune disorders. In CD, antibodies against transglutaminase 2 (TG2) and specific residues of gliadins have been identified. A similar situation is seen in rheumatoid arthritis (RA) with both anti-citrullinated protein antibodies (ACPA) and auto-antibodies against the citrullinating enzyme, peptidylarginine deiminas
Functional imaging is becoming increasingly important for the detection of neurodegenerative disorders. Perfusion MRI with arterial spin labeling (ASL) has been reported to provide promising diagnostic possibilities but is not yet widely used in routine clinical work. The aim of this study was to compare, in a clinical setting, the visual assessment of subtracted ASL CBF maps with and without addi

Objective: The minor G allele of FOXO3A rs2802292 has been associated with longevity. We aimed to investigate whether a phenotype related to healthy metabolic aging could be identified in individuals carrying the longevity-associated FOXO3A rs2802292 G allele. Research Design and Methods: rs2802292 was genotyped in a phenotypically well-characterized population of young and elderly twins (n = 190)
Evaluation, prioritization and selection of candidate requirements are of tremendous importance and impact for subsequent software development. Effort, time as well as quality constraints have to be taken into account. Typically, different stakeholders have conflicting priorities and the requirements of all these stakeholders have to be balanced in an appropriate way to ensure maximum value of the
Context: Arginine vasopressin (AVP) is known to affect liver glycogenolysis, insulin, and glucagon secretion and pituitary ACTH release. We previously showed that high copeptin, the stable C-terminal fragment of AVP prohormone, is independently associated with hyperinsulinemia and future development of diabetes mellitus. Objective: The objective of the study was to examine whether plasma copeptin
Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. The research focus naturally turns to computationally efficient bounds and high performance he
Multiple-input multiple-output (MIMO) is a mandatory feature of the Third Generation Partnership Project (3GPP) Long Term Evolution. This work investigates the performance of a low complexity channel estimator for LTE terminals with an emphasis on the 4 × 4 multiple antenna scheme. The presented work extends a promising low-complexity 2 × 2 MIMO channel estimator to the 4 × 4 MIMO case and evaluat
