High-ductility ductile iron was alloyed with 0-1.8wt% Ni in this paper. The low-temperature impact toughness test and corrosion test of simulated seawater static whole-soaking were conducted to research the effect of nickel on the low-temperature impact toughness and corrosion resistance of high-ductility ductile iron. The results show that with nickel increasing, the impact toughness under low te

The use of radio signal for position tracking (positioning) and navigation has a long tradition. Most notably, global navigation satellite systems (GNSS) are now widely applied for civilian applications, ranging all the way from tracking of cargo containers to gaming. However, GNSS suffers from limited coverage in dense urban areas and indoors and also from a limited position accuracy, which rules

A stochastic hierarchical model for the evolution of low grade gliomas is proposed. Starting with the description of cell motion using a piecewise diffusion Markov process (PDifMP) at the cellular level, we derive an equation for the density of the transition probability of this Markov process based on the generalised Fokker–Planck equation. Then, a macroscopic model is derived via parabolic limit

Numerous risks threaten modern society. Some are new, while others have existed since the beginning of time, but none have been governed on a societal level since their inception. Despite the abundance of literature addressing the governance of various risks, the processes by which they become governable in the first place have gotten little attention. As a result, this paper aims to improve our k

The as-built geometry and material properties of parts manufactured using Additive Manufacturing (AM) can differ significantly from the as-designed model and base material properties. These differences can be more pronounced in thin strut-like features (e.g., in a lattice structure), making it essential to incorporate them when designing for AM and predicting their structural behaviour. Therefore,

Over the last thirty years, suggestions for how to develop defence capability have developed rapidly. However, supporting theory and structured concept development lag behind. Despite this imbalance, countries need to continuously spend resources on defence development. This study identifies central challenges in relation to the scientific perspectives and approaches needed to support the developm

In this paper, we argue that information researchers should use images as a source of data. The information systems field is overwhelmingly visual in nature. Not only is the Internet crammed with images, but also almost every detail observed during fieldwork in different research settings can be captured in the form of digital images. Yet, we rarely engage with those images. Except for sporadic vi

Background: Treatment of common bile duct (CBD) stones after Roux-en-Y gastric bypass (RYGB) poses a particular challenge given the altered anatomy and inability to perform a standard endoscopic retrograde cholangiogram (ERC). The optimal treatment strategy for intraoperatively encountered CBD stones in post-RYGB patients has not been established. Objectives: To compare outcomes following laparosc

This paper explores the evolving landscape of regional innovation policy, focusing on the interplay between traditional cluster policies and emerging transformative agendas. Over the past decade, policy initiatives aimed at fostering place-based, collaborative innovation have proliferated. However, questions arise regarding the adequacy of existing policy tools in accommodating newer, transformati

Due to the global demographic change many more people will need to work until anolder age, and organisations and enterprises need to implement measures to facilitate an extendedworking life. The aim of this study was to investigate organisational measures and suggestionsto promote and make improvements for a healthy and sustainable working life for all ages in anextended working life. This is a qu

Archived radar data has various applications, though it is often underutilised. Nevertheless, this information has the possibility to aid in the development of accurate and relevant climate adaptation tools, inform climate-resilient urban development strategies, and numerous other personal and societal applications. Our work in the RadClim Baltic Sea Region (BSR) project established the potential

The current study presents a comprehensive research on the design, optimization, and numerical analysis of axial turbines, addressing the urgent need for more efficient and environmentally friendly energy conversion systems. With turbines being central to power generation, aviation, and marine propulsion, enhancing their performance is crucial to reducing fuel consumption, operational costs, and g
