A fundamental aspect of describing vocal activity is to quantify its overall level. For instance, everyone agrees that animals become more vocal when they are excited or stressed, but what does it mean to be ‘more vocal’? Increased duration of individual calls and their repetition rate are the most commonly reported temporal markers of arousal, but proportion of time [spent] vocalising (PTV) appea
We here present an RF-DAC-based PD featuring IQ expansion, a linearization concept using segmented non-linear RF-DACs combined with increased expansion in the IQ direction. The proposed predistorter, realized within the RF-DACs themselves, is very hardware efficient, only requiring a small amount of additional hardware compared to a conventional RF-DAC. The proposed RF-DAC-based PD, realized in a
This study evaluated the friction, wear, and airborne brake wear particle (BWP) emissions of aluminum-based metal matrix composite brake discs fabricated from recycled aluminum alloy reinforced with silicon carbide particles (Al–SiCp MMC). The study further conducted a comparative analysis of the friction, wear, and BWP emissions of Al–SiCp MMCs against those of a commercial gray cast iron (GCI) b
This study takes the perspective of civil society and aims to examine how different volunteers are framed both by others and themselves, and how terms such as ‘mixed blessing’ (used to describe volunteers as both a blessing and a curse) affect how volunteers are perceived during a crisis. Our objective is to further understand the consequences this may entail regarding how voluntary resources are
Remembrance, commemoration, and specific dates play an important role in many societies and cultures. They can be about positively connotated events with societal impacts, such as reunifications or the gaining of independence, but also disastrous or other devastating events on a national or international scale. In disaster risk areas, there are various ways such events are addressed. While for som
In this chapter we study the policy change behind the organizational restructuring of the fire and rescue services that is currently taking place in Sweden by using the multiple streams framework (MSF). We study the large forest fires in 2014 and 2018 and explain differences between the focal power of the events at the local and national levels as well as the effects the events had on subsequent p
Rural areas globally are undergoing significant social-ecological change, including emigration, demographic aging, and habitat fragmentation. These regions, often dependent on climate-sensitive livelihoods, face heightened challenges from climate change, which threatens essential infrastructures such as sanitation, transport, and communications. There is growing attention to adaptation needs in ur
The transport system is a large system of systems which currently faces challenges because of the climate-change-induced need to decrease the use of fossil fuels. The aim of mitigating climate change is realized in many parts of the transport system, concurrently and at high pace, which brings with it many challenges for the resilience of the system. By resilience, we mean the ability of a system
We present a high-performance method for real-time relighting of high-fidelity volumetric clouds. Building on Relightable Neural Assets, we introduce key adaptations that enable neural shading of volumetric cloud phenomena within a rasterization-based pipeline. In particular, we incorporate a per-pixel thickness parameter to capture view-dependent opacity and replace the generalizing single light
Innovation is widely recognized as a critical driver of socio-economic development, drawing sustained attention from both scholars and policymakers. Yet despite extensive research, a systematic and comparative understanding of how innovation studies have evolved across time and space remains limited. This study employs a bottom-up strategy using topic modeling to trace the thematic evolution of in
Reliable force estimation is essential for tool design, process stability, and adaptive control, yet direct force measurement is often impractical in production machining. This study presents a hybrid experimental-analytical framework for inverse identification of time-resolved cutting forces and process parameters during orthogonal cutting of compacted graphite iron under dry and minimum quantity
This paper examines integrating Large Language Models (LLMs) into the TRIZ contradiction matrix (TRIZ-C+LLM) to support engineering students in creative problem-solving. Experiments with three problems show that LLMs did not always improve design quality for complex tasks but reduced cognitive workload, improved understanding of contradictions, and increased perceived usefulness. Prompting experie
Recent global shocks have significantly impacted India’s Energy-Storage-Systems (ESS), revealing vulnerabilities in supply chains, investment flow, and market stability, while underscoring the urgent requirement for resilience and sustainability in this vital aspect of renewable integration. The study is grounded in Supply-Chain-Resilience-Theory and Dynamic-Capabilities-Theory and focuses on Indi
The actors providing housing to students have historically balanced precariously between the desire to care for students and the desire for disciplining them. These conflicting desires produce a tension between care and discipline that permeate institutions of student housing and their buildings. The following chapter traces how this tension played out in the formation and the first years of Swede
Despite increasing policy and industry focus on repairability, consumer repair behavior remains limited. This study examines this contradiction by analyzing user perceptions of repairable products through a survey-based approach (N = 68), focusing on behavioral, economic, and functional drivers of repair decisions. The results reveal a pronounced repairability paradox: while over two-thirds of res
The ability to achieve controlled distributions of precipitates is one of the cornerstones of alloy optimization, in which small-angle scattering (SAS) serves as a powerful technique to characterize these distributions. One method of analyzing SAS data involves form factor intensity models, where modeled distribution parameters are obtained by solving a nonlinear least-squares (NLS) problem.

Understanding the physicochemical properties of fly ash from industrial and municipal solid waste incineration is essential for its safe and efficient utilization. This study investigated the particle size distribution and elemental size partitioning in fly ash aerosols from a waste-to-energy (WtE) facility with grate-fired boilers, along with the composition of boiler deposits and ash collected i
In this chapter, we discuss research from behavior, event-related brain potentials, and neural oscillations that suggests that cognitive and neural constraints affect the timing of speech processing and language comprehension. Some of these constraints may even manifest as rhythmic patterns in linguistic behavior. We discuss two types of constraints: First, we review how the unfolding acoustic and
