Low rank inducing penalties have been proven to successfully uncover fundamental structures considered in computer vision and machine learning; however, such methods generally lead to non-convex optimization problems. Since the resulting objective is non-convex one often resorts to using standard splitting schemes such as Alternating Direction Methods of Multipliers (ADMM), or other subgradient me
Traditional phase scan method for cavity phase and amplitude setting is offline and hard to track the variations of environment and operation points. An alternative beam loading based calibration method is investigated in this paper, which might become useful online/real time calibration method.
Factorization methods are frequently used for structure from motion problems (SfM). In the presence of noise they are able to jointly estimate camera matrices and scene points in overdetermined settings, without the need for accurate initial solutions. While the early formulations were restricted to affine models, recent approaches have been show to work with pinhole cameras by minimizing object s
Collaboration involving student–industry activities entails a complex interaction between university, students, and industry. The university–student–industry triangle identified here is neither static nor balanced, and each of the three intertwined relationships displays distinguishing characteristics. Each has its own structure; the activity phases of the relationships are not synchronous, and ea
Cloud applications are often subject to unexpected events like flashcrowds and hardware failures. Users that expect a predictable behavior may abandon an unresponsive application when these events occur. Researchers and engineers addressed this problem on two separate fronts: first, they introduced replicas - copies of the application with the same functionality - for redundancy and scalability; s
The recent COVID-19 pandemic highlighted the need of non-pharmaceutical interventions in the first stages of a pandemic. Among these, lockdown policies proved unavoidable yet extremely costly from an economic perspective. To better understand the tradeoffs between economic and epidemic costs of lockdown interventions, we here focus on a simple SIR epidemic model and study lockdowns as solutions to
This essay takes those exhibits in RÊVE (Romantic Europe: The Virtual Exhibition) that are connected to “air” as points of departure for a survey of the renewed interest in air in Romantic-period cultural texts from across Europe. Scholarly interest in Romantic air has burgeoned of late but has often tended to prioritise metaphorical senses of the term or cognate terms such as atmosphere. This ess
This work explores the use of reinforcement learning to design a proactive cloud resource auto-scaler that is able to predict usage across a distributed microservice application. The focus is on serving time-sensitive workloads, e.g., industrial automation, connected XR/VR (eXtended Reality/Virtual Reality), etc., where each job has a deadline and there is some cost associated with missing a deadl
The formation of platoons, where groups of vehicles follow each other at close distances, has the potential to increase road capacity. In this paper, a decentralized control approach is presented that extends the well-known constant headway vehicle following approach to the two-dimensional case, i.e., lateral control is included in addition to the longitudinal control. The presented control scheme
Syfte: Syftet med denna studie är att undersöka kundresan på andrahandsmarknaden, där utbudet på hyllan i förväg är oklart för konsumenten. Var börjar den, hur går den till och vad händer efter ett köp av ett plagg - det ska denna studie undersöka. Frågeställning: Vad motiverar konsumenter att välja second-hand vid köp av klädesplagg? Metoden: Forskningen är baserad på en kvalitativ studie med Purpose: The purpose of this study is to investigate the customer journey in the secondary market, where the supply on the shelf is unclear to the consumer in advance. Where does it start, how does it happen and what happens after a garment is purchased - this study will examine that. Thesis question: What motivates consumers to choose second-hand when buying clothing? Methodology: The research
This Thesis seeks to give its reader the tools to understand the data privacy divide between the EU and the US. It explains the crucial notions, historical and jurisprudential factors and regulatory frameworks underlying and constituting it. First, it answers why regulating data privacy is paramount to our democratic societies on both sides of the Atlantic. The growing importance of the data dri
The aim of the study is to garner an understanding of Swedish social media users' attitudes towards the spreading of videos depicting deadly violence. To achieve this a mixed methodology was employed with a web survey that was published on social media to gather information on users' attitudes towards the phenomenon. Through the survey, participants for focus groups were found which was th
In this paper we consider adaptive distributed stabilization for uncertain multivariable linear systems with a time-varying diagonal matrix gain. We show that an unknown system matrix being an M-matrix is a sufficient condition to ensure uncertain linear systems to be stabilizable by matrix high gains, and derive a threshold condition to ensure exponential stability of uncertain linear systems sta
Fast and accurate homography estimation is essential to many computer vision applications, including scene degenerate cases and planarity detection. Such cases arise naturally in man-made environments, and failure to handle them will result in poor positioning estimates. Most modern day consumer cameras are affected by some level of radial distortion, which must be compensated for in order to get
