The polytetrafluoroethylene (PTFE) is commonly used to improve the hydrophobic of the gas diffusion layer (GDL). In this study, impacts of PTFE content and piecewise/linear gradient distributions on the transport behavior of liquid water were numerically studied by using a multiphase lattice Boltzmann method. A two-dimensional microstructure of the GDL was reconstructed by stochastic algorithm. Th

Significance efforts are underway to improve fuel cell performance, with the Polymer Electrolyte Membrane (PEM) being an essential component of Polymer Electrolyte Fuel Cells (PEFCs). The losses within the PEM can be measured through hydrogen crossover. The temperature is a critical variable that directly affects the hydrogen crossover. In this study, the hydrogen crossover and corrected current d

Using image and film advertisements, interviews, social media and public and private archives, Luxury Fashion and Media Communication offers an interdisciplinary approach to analyzing the value of the luxury object. Regular reports on consumption in media and frequent advertising on social media have allowed people all over the world to share in the issues and development of luxury; but how is it

This thesis delves into integrating control systems into cloud environments, leading to the emergence of what is commonly referred to as cloud control systems (CCSs). These systems represent a paradigm shift, leveraging the cloud’s expansive storage and computing capabilities to optimize industrial operations. However, while promising in terms of efficiency and scalability, this transition introdu

Cyber-physical Systems (CPSs) are often safety-critical and deployed in uncertain environments. Identifying scenarios where CPSs do not comply with requirements is fundamental but difficult due to the multidisciplinary nature of CPSs. We investigate the testing of control-based CPSs, where control and software engineers develop the software collaboratively. Control engineers make design assumption

This edited volume aims to bring supervision to life and contribute to a better understanding of the relationship between the supervisor and the thesis-writing student.The authors believe and hope that discussing supervision in terms of metaphors will contribute to a more profound mutual understanding between student and supervisor, a deeper understanding of the context(s) of supervision, reduce f

“Show, don’t tell” is common advice for writers of fiction. This advice is meant to encourage authors to illustrate rather than to directly state information about environments and feelings. For instance, instead of writing “she was angry,” they would write “she left the room with steady steps and slammed the door behind her,” which illustrates anger. When supervising students, I use this advice a

I det självbiografiska verket Lidandet (al-Alam) tvingas den marockanske musikern och författaren Laarbi Batma (d. 1997) att konfrontera sin egen dödlighet som cancerdrabbad.

In “Selling luxury” perfume and cosmetics stores are approached as mediated physical experiences of luxury. The elusive character of smell has forced perfume brands to invoke guides to explain how their products should be experienced. These guides may be human, in the form of sales assistants, or non-human, in the form of visual marketing materials, packaging and store displays. In the context of

PurposePatients with non-beta-hemolytic streptococcal bacteremia (NBHSB) are at risk of infective endocarditis (IE). Patients with cardiac implantable electronic device (CIED) have been described to have an increased risk of IE. The aim of the study was to describe a population-based cohort of patients with NBHSB and CIED and variables associated with IE and recurrent NBHSB.MethodsAll episodes wit

This thesis consists of literary case study of a classical Arabic travel narrative dictated by the Moroccan scholar and Ṣūfī Yūsuf ʾibn ʿĀbid al-Fāsī (يوسف بن عابد الفاسي) (d.1048/1638) in his new-found home in Hadramawt, Yemen. The study seeks to investigate the Ṣūfī dimension of the corpus text and address its legacy within the riḥla tradition (AR. الرحلة al-riḥla) by the usage of Ṣūfī elements,

Recently, Ombashi et al. published a systematic review aiming to identify the pitfalls in the development and implementation as well as factors influencing long-term success of a multidisciplinary, international registry for cleft care on a global scale. The purpose of this letter to the editor is to highlight that the review failed to include the Swedish quality registry for patients born with clRecently, Ombashi et al. published a systematic review aiming to identify the pitfalls in the development and implementation as well as factors influencing long-term success of a multidisciplinary, international registry for cleft care on a global scale.

Social media influencing is a phenomenon that is constituted by the combination of human beings and their digital personae. Via this combination, communication takes place in a context of contracting and expanding spatial relations. This chapter analyses social media influencing as an outcome of the socio-materially produced and consumed spatial relations that are found in cyberspace. It is based

Knock in spark ignition (SI) engines occurs when the air–fuel mixture in the combustion chamber ignites spontaneously ahead of the flame front, reducing combustion efficiency and possibly leading to engine damage if left unattended. The use of knock sensors to prevent it is common practice in modern engines. Another measure to mitigate knock is the use of higher-octane fuels. The American Society

This text will explore the allegedly ‘sustainable’ urbanization of agricultural land in the SUD project Hyllie, an emerging ‘smart city’ district in southern Malmö (Sweden’s third largest city). With the aim to provoke discussions on some often-overlooked dilemmas with the expansionist and projective character of SUD, the concept of ‘queer failure’ is brought in as a disruptive and generative idea

Introduction: Symptom distress and impaired psychological well-being after liver transplantation may lead to limitations in everyday activities and lowered health-related quality of life. The aim of this nationwide, descriptive, and cross-sectional study was to explore self-reported symptom occurrence and distress, among Danish liver transplant recipients, and their association with self-reported
