Low-dimensional parametric models are the de-facto standard in computer vision for intrinsic camera calibration. These models explicitly describe the mapping between incoming viewing rays and image pixels. In this paper, we explore an alternative approach which implicitly models the lens distortion. The main idea is to replace the parametric model with a regularization term that ensures the latent

Visibility across supply chains has been a key concern for organisations for many years, but the tools and information systems to achieve real-time visibility have not been available until recently. In response to uncertainty and complexity, advanced information and communication technologies have been explored for supply chain visibility (SCV). However, managerial perspectives are largely absent
The Veiki moraine in northern Sweden, a geomorphologically distinct landscape of ice-walled lake plains, has been interpreted to represent the former margin of an intermediate-sized pre–Last Glacial Maximum (LGM) Fennoscandian ice sheet, but its age is debated as either marine isotope stage (MIS) 5c or MIS 3. We have applied optically stimulated luminescence (OSL) and radiocarbon dating to four si
Contact-rich manipulation tasks remain a hard problem in robotics that requires interaction with unstructured environments. Reinforcement Learning (RL) is one potential solution to such problems, as it has been successfully demonstrated on complex continuous control tasks. Nevertheless, current state-of-the-art methods require policy training in simulation to prevent undesired behavior and later d
AimTo investigate the complete clinical spectrum of individuals with paediatric tuberous sclerosis complex in southern Sweden and explore changes over time.MethodsIn this retrospective observational study, 52 individuals aged up to 18 years at the study start were followed-up at regional hospitals and centres for habilitation from 2000 to 2020.ResultsCardiac rhabdomyoma was detected prenatally/neo
This paper presents an implementation for a baseband massive multiple-input multiple-output (MIMO) application-specific instruction set processor (ASIP). The ASIP is geared with vector processing capabilities in the form of single instruction multiple data (SIMD), and furthermore exploits instruction level parallelism by employing a very large instruction word (VLIW) architecture. Additionally, a
Objective: This study examined the overlap between considering oneself to have stopped nonsuicidal self-injury (NSSI) and the actual cessation of the behavior in terms of days self-injured in the last month and last year, and how these operationalizations are associated with constructs related to NSSI recovery. Methods: A cross-sectional survey including measures of coping, emotion dysregulation,
The discovery that the CRISPR/Cas9 system could be used for genome editing purposes represented a major breakthrough in the field. This advancement has notably facilitated the introduction or correction of disease-specific mutations in healthy or disease stem cell lines respectively; therefore, easing disease modeling studies in combination with differentiation protocols. For many years, variabili
Vanuatu sand drawing has been listed by UNESCO since 2006 and has both fascinated and puzzled researchers from various disciplines for over a century. The inherent multi-dimensionality of the practice makes analysis complex, and until very recently developing a systematic methodology to study this intangible art form was difficult. This paper aims to contribute to filling this gap with the analysi
This article presents the results of survey-based research which explores if licensed aircraft maintenance engineers working in Norway, Sweden, and Portugal experience regulated “just culture” as procedural justice-infused processes when occurrence reporting in European Union (EU) civil aviation. Drawing on Tylerian procedural justice theory, the study finds that, perceived procedural justice is m
The purpose of this paper is to simplify the standard framework integrating epidemiological and economic concerns. We present a model where a social planner can influence the spread-intensity of an infection wave through a single parameter. The spread-intensity affects both economic activity and population health. We study the planner's optimal trade-off between upholding economic activity and pre
This book probes into the dynamics between Orthodox Christianity and the COVID-19 pandemic, unraveling a profound transformation at institutional and grassroots levels. Employing a multidisciplinary approach, and drawing upon varied data sources, including surveys, digital ethnography, and process tracing, it presents unprecedented insights into church-state relations, religious practices, and the
The purpose of this study is to examine how teachers’ PCK is expressed in science teaching practice, both from a teacher’s and a student’s perspective. It is a qualitative study of three teachers’ physics classroom lectures in grades 7 and 8. International research has highlighted the impact of teachers on students’ achievement in general and in science education in particular, and several ongoing
Due to the negative environmental impacts along the life cycle of fossil-based plastics, there is an increased interest in the development of biobased and biodegradable plastics. Especially, biodegradable bioplastics possess different material characteristics than fossil-based plastics and can therefore be expected to perform differently during the product use and in end-of-life (EOL) phases. Thus
Temperature and coagulant types have an important impact on the quantity and quality of the residue (sludge) in water and wastewater treatment processes. Temperature influences water viscosity and the distribution of the coagulant in water. Coagulants can promote the agglomeration of fine particles into larger flocs so that they can be more easily separated from the water. Experiments have been co
Background: A new, supposedly more reproducible radiographic classification, set to replace the Tönnis classification of hip dislocations, was proposed in 2015: the International Hip Dysplasia Institute (IHDI) classification. Purpose: To compare the IHDI classification with the Tönnis classification when evaluating the severity of hip dislocations as well as their respective inter- and intra-obser
This chapter examines the nature of the interaction between the Georgian Orthodox Church (GOC) and the state during the pandemic. The article shows how the church’s gradual acknowledgment of the deadly character of the virus coincided with a strict adherence to certain highly risky religious practices (such as communion from the same spoon), while the Georgian government’s stance in defense of pub
Background: Liver disease in Cystic Fibrosis (CFLD) is an early complication of CF. Evidence of CFLD is often subclinical and screening is recommended. Screening includes a biochemical work-up and an ultrasound investigation. Non-invasive methods measuring liver stiffness such as shear wave elastography could be beneficial. This study describes the use of 2D Shear Wave Elastography (2D SWE) in scr
