Background: The genetic architecture of birth size may differ geographically and over time. We examined differences in the genetic and environmental contributions to birthweight, length and ponderal index (PI) across geographical-cultural regions (Europe, North America and Australia, and East Asia) and across birth cohorts, and how gestational age modifies these effects. Methods: Data from 26 twin
This Master’s thesis project concerns developing statistical methods to examine sea level data provided by the Swedish Meteorological and Hydrological Institute (SMHI). The data comes from sea level gauges located in the harbours of Uddevalla, Ängelholm and Åhus along the Swedish coast. These three gauges are mobile, as compared to the permanent sea level gauges used by the SMHI at various points
The area of autonomous parking attracts a great deal of attention from the research community and the automobile industry. Research has showed that many robotic navigation systems fail to deliver the performance and flexibility of animal navigation techniques, even though they are both mathematically and technologically complex. Biomimetic robotic research, i.e., research that tries to mimic biolo
Corruption and lack of transparency go hand in hand in poor countries. As most corrupt countries in the world can be found on the African continent, these countries have become a main target for strategies with anti-corruption movements. Despite the widespread phenomenon of corruption in this area, the technology development is prosperous, and owning a mobile phone is more common than having a toi
Syftet med detta examensarbete var att undersöka hur agil utveckling och användarcentrerad design kan kombineras i en utvecklingsprocess. Undersökningen baseras sig på den utvecklingsprocess med Scrum som används på en sektion vid avdelningen Applikationer och Service på Sony Mobile Communications AB i Lund, Sverige. Det första målet med examensarbetet var att förse sektionen med ett antal förslaThe main purpose of this master´s thesis was to investigate how agile development and user-centered design can be combined in a development process. The target development process for this investigation was a development process at a section in the department Application and Service at Sony Mobile Communications AB in Lund, Sweden. The first goal of the thesis was to provide the section with a set
Connectivity between and within places is one of the cornerstones of geography. However, the data and methodologies used to capture connectivity are limited due to the difficulty in gathering and analysing detailed observations in time and space. Mobile phone data potentially offer a rich and unprecedented source of data, which is exhaustive in time and space following movements and communication
Background: Mobile app-based tools have the potential to yield rapid, cost-effective, and sensitive measures for detecting dementia-related cognitive impairment in clinical and research settings. At the same time, there is a substantial need to validate these tools in real-life settings. The primary aim of this study was thus to evaluate the feasibility, validity, and reliability of mobile app-bas
The tremendous amount of multimedia applications running across the wireless communication medium makes quality of service (QoS) a fundamental requirement for mobile ad hoc networks. However, it is not easy to incorporate QoS into these networks. Moreover, the growing number of group-oriented applications also necessitates the efficient utilisation of network resources. The multicast model is a pr
People have become more and more mobile as a result of advancements in wireless communications technologies. The mobile phone as an enabler of this increased mobility has become an ever more important part of our society but comparatively little research has been done concerning mobile services at the organisational level as opposed to the individual level. With our study we wish to contribute to
In advective-dispersive simulations of aquifers, retardation factors using linear adsorption isotherms are commonly employed to represent the adsorption-desorption process for solutes in soil. In particular, the retardation factors that use entire pore space (total porosity) or effective pore space (effective porosity) are widely used. Although another retardation factor that describes solute tran
Objective: Falls and related injuries are known to be the major health problem leading to disability and mortality among older adults. Identification and management of fall risks aimed to prevent falling is considered to be essential. The aim of this study was to develop a mobile application for screening and management of fall risks based for older adults. Method and materials: First, we determin
