Brief announcement : Leader election in SINR model with arbitrary power control
(Association for Computing Machinery, 2017-07-26) Halldórsson, Magnús M.; Holzer, Stephan; Markatou, Evangelia Anna; Department of Computer Science
In this article, we study the leader election problem in the Signal-to-Interference-plus-Noise-Ratio (SINR) model where nodes can adjust their transmission power. We show that in this setting it is possible to solve the leader election problem in two communication rounds, with high probability. Previously, it was known that (log n) rounds were sufficient and necessary when using uniform power, where n is the number of nodes in the network. We then examine how much power control is needed to achieve fast leader election. We show that any 2-round leader election algorithm in the SINR model running correctly w.h.p. requires a power range 2Ω(n) even when n is known. We match this with an algorithm that uses power range 2Θ(n), when n is known and 2Õ (n1.5) when n is not known. We also explore tradeoffs between time and power used, and show that to elect a leader in t rounds, a power range exp(n1/Θ(t)) is sufficient and necessary.
A Conceptual Model For Web Accessibility Requirements In Agile Development
(Association for Computing Machinery, Inc, 2024-08-07) Miranda, Darliane; Araújo, João; Liebel, Grischa; Department of Computer Science
Accessibility is the practice of making content and functionality accessible to all users, regardless of their abilities. Although accessibility is a highly relevant quality attribute, it is often treated as an afterthought in software development, unfortunately excluding people with disabilities from using many web-based systems. Specifically in agile development, sprints focus on new features and quality attributes, such as accessibility, are often not considered sufficiently. In these cases, using conceptual models to understand and analyze requirements that developers have formulated as a set of related user stories is a research opportunity. To increase agile professionals' focus on accessibility, we built a conceptual model for web accessibility, identifying artifacts and concepts used in agile development to specify accessibility. We discuss how this model can be used as a guide to better integrate accessibility considerations into agile software development. Researchers can use the result to define resources that are not currently covered or improve underutilized practices. We plan to use the conceptual model in the next steps to adapt existing agile artifacts and create support tools for web accessibility in agile development.

Implementation of a whole blood programme within a blood service : Practical guidance for blood providers
(2026-03) European Blood Alliance Working Group on Innovations and New Products; Department of Engineering
Background and Objectives: Early balanced transfusion is recommended for resuscitation of patients with severe bleeding. Whole blood (WB) is reintroduced as a feasible alternative to blood components, as it includes red blood cells, plasma and platelets in a physiological ratio. Materials and Methods: In this review, we aim to provide practical guidance and a framework for blood providers aiming to implement a WB programme. The review summarizes recommendations and practical implications identified from published literature, regulatory requirements and current programmes. Results: WB donors are selected based on national donor selection criteria. When the patients' ABO-type is unknown, low titre anti-A and anti-B group-O WB (LTOWB) are recommended. ABO-group type-specific blood can be used in patients with known ABO type. Anticoagulants include CPD and CPDA-1. Leukoreduction can be performed with a platelet-sparing filter. WB is stored at +2 to –6°C for up to 35 days. Rotation of the stock and re-manufacturing to red cell concentrates minimizes outdating. The EDQM Guide to the preparation, use and quality assurance of blood components provides the minimum requirements. Post-implementation follow-up includes haemovigilance and quality surveillance. End users should be involved in the development of the programme and training of personnel. Emergency collection of WB can enable transfusion to patients in remote areas, during disasters and during war. Conclusion: We conclude that implementation of a WB programme for routine and emergency management of patients with severe bleeding can be performed in a structured, safe and sustainable way.
Unsupervised machine learning in sleep research : a scoping review
(2025-11-01) Biedebach, Luka; Ferreira-Santos, Daniela; Stefanos, Marie Ange; Lindhagen, Alva; Pires, Gabriel Natan; Arnardóttir, Erna Sif; Islind, Anna Sigridur; Department of Engineering; Department of Computer Science
Study Objectives Unsupervised machine learning—an approach that identifies patterns and structures within data without relying on labels—has demonstrated remarkable success in various domains of sleep research. This underscores the broader utility of machine learning, suggesting that its capabilities extend beyond current applications and warrant further exploration for novel insights in sleep studies, focusing specifically on unsupervised machine learning. Methods This paper outlines a scoping review conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines for scoping reviews. A comprehensive search covering various search terms focusing on the intersection between unsupervised machine learning and sleep led to 3960 publications. After screening all titles and abstracts with two independent reviewers, ultimately, 356 publications were included in the full-text review. The data extracted from the full texts included information about the machine learning methods and types of sleep data, as well as the study population. Results There has been a steep increase in the number of publications in this research area in the past 10 years. Clustering is the most commonly used method, but other methods are gaining popularity. Apart from classical polysomnography, data from wearable devices, nearables, video, audio, and medical imaging techniques have been used as input to unsupervised machine learning. The broad search allowed us to explore various applications within sleep research, ranging from the general population to populations with various sleep disorders. Conclusion The review mapped existing research on unsupervised learning in sleep research, identified gaps in the literature, and derived directions for future research.
