A controller for critical vehicle maneuvering is proposed that avoids obstacles and keeps the vehicle on the road while achieving heavy braking. It operates at the limit of friction and is structured in two main steps: a motion-planning step based on receding-horizon planning to obtain acceleration-vector references, and a low-level controller for following these acceleration references and transf

Distributed surveillance systems typically consist of multiple cameras that need to store some fraction of their video streams at a central storage node. The disk space of this node constitutes a shared resource. In the paper the disk space allocation is formulated as a PI control problem and a new method for enforcing global resource constraints inspired by anti-windup tracking is proposed. The a

Increasingly fine-grained cloud billing creates incentives to review the software execution footprint in virtual environments. For example, virtual execution environments move towards lower overhead: from virtual machines to containers, unikernels, and serverless cloud computing. However, the execution footprint of security components in virtualized environments has either remained the same or eve

One of the most significant obstacles for the every­day use of systems based on Brain­Computer Inter­faces (BCIs) is the tediousness of calibration. Successful improvements on calibration, particularly the time needed and the user­experience, have been made with, e.g., transfer learning, gamification, and task estimation [1, 2, 3]. Inthis work, we present an adaptive approach to BCI systems’ calib

The Covid-19 pandemic has spawned numerous dynamic modeling attempts aimed at estimation, prediction, and ultimately control. The predictive power of these attempts has varied, and there remains a lack of consensus regarding the mechanisms of virus spread and the effectiveness of various non-pharmaceutical interventions that have been enforced regionally as well as nationally. Setting out in data

The increased use of cloud and other large scale datacenter IT services and the associated power usage has put the spotlight on more energy-efficient datacenter management. In this paper, a simple model was developed to represent the heat rejection system and energy usage in a small DC setup. The model was then controlled by a reinforcement learning agent that handles both the load balancing of th

We study an optimal control problem for a simple transportation model on a path graph. We give a closed form solution for the optimal controller, which can also account for planned disturbances using feed-forward. The optimal controller is highly structured, which allows the controller to be implemented using only local communication, conducted through two sweeps through the graph.

The purpose of this thesis is to analyse the identity of the Chilean environmental movement in relation to the Chilean nation-state. The theme is discussed through theories of social constructivism, identity and social movements. Of central focus is to discuss the role of the environmental movement in constructing environmental policy and in relation to national identity. The thesis draws on empir

Nowadays the private sector tends to increase its engagement into social and environmental issues and cooperate with the public organizations in order to contribute to the development of the societies where the companies operate and also mitigate the environmental damages incurred by industry. The increase in social responsibility by private firms is generally articulated by and pursued through th

This report deals with an evaluation study carried out on the community based accident prevention program being run by the municipal fire and rescue brigades in Landskrona and Svalöv. A major survey shows only a few results that could determine differences as statistically significant in fire safety behavior between the study group (inhabitants in Landskrona and Svalöv) and controll groups, but th

Changing climatic conditions is a perpetual circumstance for mankind. In this study, we investigate local environmental and climatic changes near Kangerlussuaq, west Greenland. Our reconstruction is based on a lake sediment core and methods include chemical proxies and a palynological analysis. The investigated site is located 15 km from the Aasivissuit Inuit summer hunting ground, which has been

The present study being the second volume of Variations on Ah! vous dirai-je, Maman (2019) highlights two important parameters of flute playing and musical expression: On Practice, Intervals and Sons filés.

The present study being the third volume of Variations on Ah! vous dirai-je, Maman (2020) highlights four important parameters of flute playing: Timbre, Expression, Resonance and Projection.

In post-quantum cryptography (PQC), Learning With Errors (LWE) is one of the dominant underlying mathematical problems. For example, in NIST's PQC standardization process, the Key Encapsulation Mechanism (KEM) protocol chosen for standardization was Kyber, an LWE-based scheme. The primal and the dual attacks are the two main strategies considered for solving the underlying LWE problem of multiple

The 5th generation of mobile networks introduces a new Network Function (NF) that was not present in previous generations, namely the Network Data Analytics Function (NWDAF). Its primary objective is to provide advanced analytics services to various entities within the network and also towards external application services in the 5G ecosystem. One of the key use cases of NWDAF is mobility trajecto

As a counterweight to depersonalization, dementia care settings collect personal biographies, life stories, when residents move in. In Sweden, life story work has established itself as an indicator when measuring quality in dementia care. To facilitate the writing of life stories, care settings use a variety of life story templates, with a set of questions to be filled in about the care recipient.

BACKGROUND: Gout is an inflammatory arthritis manifesting as acute episodes of severe joint pain and swelling, which can progress to chronic tophaceous or chronic erosive gout, or both. Here, we present the most up-to-date global, regional, and national estimates for prevalence and years lived with disability (YLDs) due to gout by sex, age, and location from the Global Burden of Diseases, Injuries
