Man brukar höra att evolution handlar om att de starkaste, de bäst lämpade, överlever. Detta för tankarna till en värld full med översittare, som hänsynslöst driver fram och lämnar de svaga bakom sig. Men det behöver inte vara så. Denna avhandling visar oss att gemenskap är styrka, och att evolutionen skapar liv där de svaga ibland sitter på de starkas axlar.Strutsar är märkliga varelser. De ser uPeople are used to hearing that evolution is about the survival of the fittest. Theyimagine a world full of bullies that ruthlessly fight their way to the top in the struggle for life, leaving the weak behind. But this doesn’t need be the case. This thesis reveals a different side of evolution, where survival means working together, and where the weak can ride on the shoulders of the fit.Ostriches

In this paper, we perform a belief propagation (BP) decoding threshold analysis of spatially coupled (SC) turbo-like codes (TCs) (SC-TCs) on the additive white Gaussian noise (AWGN) channel. We review Monte-Carlo density evolution (MC-DE) and efficient prediction methods, which determine the BP thresholds of SC-TCs over the AWGN channel. We demonstrate that instead of performing time-consuming MC-

Through a detailed examination of the use of the lexical item bit in four English language corpora, this study assesses whether the assumptions guiding a meaning potential perspective on lexical meaning (e.g. Allwood 1999, 2003; Croft and Cruse 2004, Paradis 2005; Fauconnier 2007) are reconcilable with a practicable description and explanation of attested language use. To this end, the study emplo

There is huge potential to increase installation of photovoltaics (PV) using the roofs of non-residential buildings. While barriers to and enablers of the adoption of PV in residential buildings are well studied, this is not the case for non-residential buildings. This article is intended to fill this research gap by mapping barriers to and enablers of PV adoption by property owners of non-residen

Predictive information and maintenance optimization for deteriorating structures is concerned with scheduling (a) the collection of information by inspection and monitoring and (b) maintenance actions such as repair, replacement, and retrofitting based on updated predictions of the future condition of the structural system. In this article, we consider the problem of jointly identifying—at the beg

Although science has been a formidably successful force of social and technological development in the modern era, and a main reason for the wealth and well-being of current societies compared to previous times, a fundamental distrust characterizes its current status in society. According to prevalent discourse, science is insufficiently productive and in need of stricter governance and bureaucrat

The institution of science is said to be under pressure from political, economic and social interests, manifested in alleged bureaucratization, managerial reforms, anti-intellectual movements on university campuses, and widespread questioning of expert knowledge in society. Commercialization of academic publishing and the growth of competitive funding have increased the importance of journal and g
