Resilience is a debated concept with numerous definitions. If focusing on describing a community under stress of a particular disruptive event, its more traditional etymological meaning of ability to spring back after deformation, or its more applied meaning of ability to cope with and recover from the event, are sufficient. However, if focusing on building and maintaining resilient communities ov
Airborne Laser Scanning (ALS) is used to acquire three-dimensional (3D) city model data over large areas. However, because of the long ALS update cycle, building information models (BIM) could be utilized to maintain city models. In this study, we designed, implemented, and evaluated a methodology to formalize the integration of BIM data into city models. CityGML models were created from BIM data
In this paper, we study the trade-off between complexity and performance in massive MIMO systems with neural-network based digital pre-distortion (NN-DPD) blocks at the base station. In particular, we consider a multi-user massive MIMO system with per-antenna NN-DPDs, each with an adjustable NN architecture in terms of the size and the number of NN hidden layers. We first analyze the system perfor
Understanding the nature and origin of the precursor material to terrestrial planets is key to deciphering the mechanisms and timescales of planet formation1. Nucleosynthetic variability among rocky Solar System bodies can trace the composition of planetary building blocks2–5. Here we report the nucleosynthetic composition of silicon (μ30Si), the most abundant refractory planet-building element, i
Several countries use capability assessments as a part of their efforts to manage risk. However, it is unclear how such assessments are connected to other risk management activities, e.g. risk assessment. Therefore, the aim of the present paper is to present a study of how capability assessment is related to risk assessment. Capability assessment methods were identified through a scoping study and
Capacity development for disaster risk reduction (DRR) has been identified as one of the main ways of substantially reducing disaster losses. In previous research, several elements have been identified that are important in capacity development for DRR. For this study, documentation from nine international capacity development projects for DRR has been analysed. The projects were undertaken by a S
A conceptual framework for systematically studying and analysing risk governance is introduced. The framework, which is influenced by design science, is particularly valuable for relating the way risks are handled at the micro-level to aspects at the macro-level. Three central concepts are included in the framework: purpose, function, and form. A function is used to denote what a specific system d
Context. Extremely metal-poor (EMP) stars preserve a fossil record of the composition of the ISM when the Galaxy formed. It is crucial, however, to verify whether internal mixing has modified their surface composition, especially in the giants where most elements can be studied. Aims. We aim to understand the CNO abundance variations found in some, but not all EMP field giants analysed earlier. Mi
Effective disaster risk management is a requisite for sustainable development and it is paramount to include a wide range of stakeholders to manage risk in this context. Recent research indicates the significance of making ideas of what is valuable and important to protect explicit in any disaster risk management initiative that involves several stake- holders. The purpose of this article is thus
Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guid
We pursued the following three interconnected points: (1) there are unexplored opportunities for resilience scholars from different disciplines to cross-inspire and inform, (2) a systems perspective may enhance understanding of human resilience in health and social settings, and (3) resilience is often considered to be fractal, i.e., a phenomenon with recognizable or recurring features at a variet
Capacity development for disaster risk reduction is an important process to substantially reduce disaster losses, which threaten sustainable development and the achievement of the Millennium Development Goals. This paper presents seven elements for capacity development for disaster risk reduction that has been applied in practise with noteworthy results. The seven elements are: (1) Terminology, (2
Purpose - The purpose of this paper is to examine if gendered differences in risk perception automatically mean that women and men rank the hazards of their community differently, focusing any risk reduction measures on the priority risks of only part of the population. Design/methodology/approach - The study applies survey research through structured personal interviews in three municipalities in
South Africa is a complex and dynamic society, with overwhelming and increasing problems with disaster risk in the vulnerable urban communities in and around its rapidly growing metropolitan centres. The purpose of this study is to improve the understanding of the challenges for disaster risk reduction in such communities. It focuses on the case of Imizamo Yethu, in the Western Cape, in order to b
