Abstract

Quality attributes, such as performance or reliability, are crucial for the success of a software system and largely influenced by the software architecture. Their quantitative prediction supports systematic, goal-oriented software design and forms a base of an engineering approach to software design. This thesis proposes a method and tool to automatically improve component-based software architecture (CBA) models based on such quantitative quality prediction techniques.

Abstract

From Pavlov's dog expecting food when hearing a bell to stereotypes as expectations about other people’s behaviour, from Bandura’s self-efficacy as expectation for success and failure of one’s own behaviour to the "predictive brain" concept in current perception theories: expectations have been a central construct in different areas of psychological research. In each of these areas, specific concepts, theoretical approaches, and empirical methods have been developed to explain when and why expectations persist and when they do not. Many theories assume that expectations are likely to change in the face of disconfirming evidence. However, sometimes expectations persist even though they are empirically violated, suggesting that they can be “sticky” under certain circumstances. But what are these circumstances? And what are the psychological mechanisms that can explain why and when expectations persist or change after being confronted with expectation-violating evidence?Each contribution of the current book offers insights into individuals’ reactions to violations of expectations. They show that many pieces of the puzzle have been collected in the many sub-displiclines of psychology and that putting them together in an integrative fashion stays a fascinating enterprise.

Abstract

The aim of this Research Topic was to collate articles describing prediction of outcomes of pre- and perinatal lesions leading to cerebral palsy, basic research in animal models and human subjects, and ideas for, and trials of, interventions in the first two years of life.CP arises from insults to the sensorimotor cortex, subcortical axon tracts and subplate. The aetiology is complex and often multifactorial. The outcome is not simply a loss of voluntary control due to disruption of descending pathways, but also involves abnormal development of reflex and corticospinal circuitry. CP may be viewed as aberrant plasticity in response to a lesion, indeed, abnormalities in movement are subtle at first but develop subsequently. It is misleading to suppose that developmental mechanisms are self-reparative. The challenge is to understand activitydependent fine tuning of neural circuitry during normal development and to find how to promote desirable plasticity whilst limiting undesirable effects following developmental lesions. However, before proposing interventions, we have to develop our ability to predict the severity of neonatal insults.We solicited a variety of articles, including long and short reviews, original research and opinion pieces, from both basic scientists and clinicians. Likewise we, as editors, have complementary knowledge and experience in this area. Anna Basu is an academic pediatric neurologist and Gavin Clowry is a developmental neuroscientist.

Abstract

This book places tipping points in their scientific, economic, governmental, creative, and spiritual contexts. It seeks to offer a comprehensive set of interpretations on the meaning and application of tipping points. Its contribution focuses on the various characterisations and metaphors of tipping points, on the scope for anticipating their onset, the capacity for societal resilience in the face of their impending arrival, and for better ways of communicating and preparing societies, economies, and governments for accommodating them, and hence to turn them into responses which buffer and better human well-being. Above all, the possibility of preparing society for creative and benign ‘tips’ is a unifying theme. The conclusion is sombre but not without hope. Thresholds of profound change can combine earth system-based relatively abrupt shifts with human-caused alterations of these disturbed patterns which, coupled together, produce more rapid onsets and greater tensions and stresses for governments and economies, as well as socially unequal societies. There is still time to predict and address these thresholds but too much delay will make the task of accommodation very difficult to achieve with relevant-scale community support. There are many examples of adaptive resilience throughout the world. These should be identified, supported, and emulated according to cultural acceptance and emerging economic realities. But there is no guarantee that the necessary adjustments can be made in time, as emerging patterns of outlook and governance do not appear to be conducive to manage the very awkward transitions of appropriate response.

Abstract

Big data is revolutionizing our ability to measure and study the human brain. New technology increases the resolution of images that are being study as well as enables researchers to study the brain as it functions. These technological advances are combined with efforts to collect neuroimaging data on large numbers of subjects, in some cases longitudinally. This combination of advances in measurement and scope of studies requires novel development in the statistical analysis. Fast, scalable, robust and accurate models and approaches need to be developed to make headway on these problems. This volume represents a unique collection of researchers providing deep insights on the statistical analysis of big neuroimaging data.

Abstract

In Global Navigation Satellite Systems (GNSS), the on-board clocks are a key component from which timing and navigation signals are generated. This thesis reviews the performance of the first Passive Hydrogen Maser (PHM) launched by the Galileo system in 2008; and demonstrates how the new PHM can be consider as the best clock in space, pushing the physical clock error contribution below the noise floor of geodetic time transfer capabilities. Furthermore, overall GNSS clock peformance is reviewed

Abstract

The software execution environment can play a crucial role when analyzing the performance of a software system. In this book, a novel approach for the automated detection of performance-relevant properties of the execution environment is presented. The properties are detected using predefined experiments and integrated into performance prediction tools. The approach is applied to experiments for detecting different CPU, OS, and virtualization properties, and validated in different case studies.

Abstract

While the present state of knowledge on the time dependent deformation behaviour of normal and high-strength concrete may be considered as sufficiently determined, the creep and shrinkage of lightweight aggregate (LWA) concrete, particularly of high-strength LWA concrete, can only be specified inadequately. On the basis of the experimental results a prediction model for shrinkage and creep of structural lightweight aggregate concrete was developed.

Abstract

This dissertation thesis presents an approach enabling the modelling and quality-of-service prediction of event-based systems at the architecture-level. Applying a two-step model refinement transformation, the approach integrates platform-specific performance influences of the underlying middleware while enabling the use of different existing analytical and simulation-based prediction techniques.

Abstract

Across almost all standard indicators, the Indigenous population of Australia has worse outcomes than the non-Indigenous population. Despite the abundance of statistics and a plethora of government reports on Indigenous outcomes, there is very little information on how Indigenous disadvantage accumulates or is mitigated through time at the individual level. The research that is available highlights two key findings. Firstly, that Indigenous disadvantage starts from a very early age and widens over time. Secondly, that the timing of key life events including education attendance, marriage, childbirth and retirement occur on average at different ages for the Indigenous compared to the non-Indigenous population. To target policy interventions that will contribute to meeting the Council of Australian Governments’ (COAG) Closing the Gap targets, it is important to understand and acknowledge the differences between the Indigenous and non-Indigenous lifecourse in Australia, as well as the factors that lead to variation within the Indigenous population.
