We propose a method for estimating the 3D position of a target point, given multiple measurements of it, using mm-wave radar data. Given azimuth headings and range estimates from posed radar positions, we find the 3D position, using an approximate, but geometrically and statistically meaningful cost. The 3D position is found in an optimal way, using this approximate cost. By deriving the Lagrangia
We perform a validation analysis on the multipolar model of opinion dynamics. A general methodology for using the model on datasets of two correlated variables is proposed and tested using data on the relationship between COVID-19 vaccination rates and political participation in Sweden. The model is shown to successfully capture the opinion segregation demonstrated by the data and spatial correlat
The standard approach for visual place recognition is to use global image descriptors to retrieve the most similar database images for a given query image. The results can then be further improved with re-ranking methods that re-order the top scoring images. However, existing methods focus on re-ranking based on the same image descriptors that were used for the initial retrieval, which we argue pr
This report details the collaborative project between the Author, Zenit Design AB which is performed on behalf of the bluetooth speaker manufacturer, Orlo AB. The Project is divided in two parts, where the first aims to identify a new market where Orlo’s technical expertise will benefit the user in a unique way and the secondary part is about designing a speaker for the said market. Several poten
This paper studies the relationship between income inequality and carbon emissions in the United States between 1929 and 2019. We contribute to the literature by taking a long-term perspective, which allows us to study how the relationship has varied over time. Our results show that higher inequality was associated with lower emissions during the early part of the sample and higher emissions towarThis paper studies the relationship between income inequality and carbon emissions in the United States between 1929 and 2019.

We previously reported that indoor odorous chloroanisoles (CAs) are still being emitted due to microbial methylation of hazardous chlorophenols (CPs) present in legacy wood preservatives. Meanwhile, Swedish researchers reported that this malodor, described since the early 1970s, is caused by hazardous mold. Here, we examined to what extent CP-treated wood contains mold and if mold correlates with
In order to allow for a computationally efficient estimation of radar reflections, one commonly assumes the reflecting target to be in the far-field of the sensing array, such that the impinging wavefront is modeled as a linear phase-shift along the array. This works well in most radar scenarios, but causes significant performance degradation for close-range radar systems, wherein the curvature of
This paper addresses the hybrid quantized signal detection problem in a distributed radar system, where widely separated antennas transmit low-bit quantized data with varying quantization levels depending on the different bandwidth constraint for each channel to a fusion center. To enable a high detection performance with such hybrid quantized data, we formulate the generalized likelihood ratio, R
In this paper, we argue that modern pre-integration methods for inertial measurement units (IMUs) are accurate enough to ignore the drift for short time intervals. This allows us to consider a simplified camera model, which in turn admits further intrinsic calibration. We develop the first-ever solver to jointly solve the relative pose problem with unknown and equal focal length and radial distort
This paper considers the problem of jointly designing the transmit waveforms and weights for a frequency diverse array (FDA) in a spectrally congested environment in which unintentional spectral interferences exist. Exploiting the properties of the interference signal induced by the processing of the multi-channel mixing and low-pass filtering FDA receiver, the interference covariance matrix struc
In this paper, we focus on the design of the transmit waveforms of a frequency diverse array (FDA) in order to improve the output signal-to-interference-plus-noise ratio (SINR) in the presence of signal-dependent mainlobe interference. Since the classical multi-carrier matched filtering-based FDA receiver cannot effectively utilize the waveform diversity of FDA, a novel FDA receiver framework base
We present novel approaches involving generative adversarial networks and diffusion models in order to synthesize high-quality, live, and spoof fingerprint images while preserving features such as uniqueness and diversity. We generate live fingerprints from noise with a variety of methods, and we use image translation techniques to translate live fingerprint images to spoof. To generate different
This article explores the potential for just knowledge production in Urban Living Labs (ULLs) by foregrounding epistemic justice. Drawing on autoethnographic and ethnographic methods, it examines how testimonial and hermeneutical injustices shape the formation, implementation, and dissemination phases of EU-funded, research-led ULLs. Findings show that funding structures, academic framings, and di
Understanding 3D human interactions is fundamental for fine-grained scene analysis and behavioural modeling. However, most of the existing models predict incorrect, lifeless 3D estimates, that miss the subtle human contact aspects–the essence of the event–and are of little use for detailed behavioral understanding. This paper addresses such issues with several contributions: (1) we introduce model
Introduction. The ability to read and interpret different types of text can be significantly impacted by neuropsychiatric disabilities, which affect cognitive abilities. This paper explores and reviews previous studies within library and information science on neuropsychiatric disabilities in relation to reading practices. Method. Searches were performed in LISA and LISTA to identify research on
In this paper we propose minimal solvers for relative pose estimation for two views of the projected silhouettes of two 3D cylinders. Using such line features instead of the standard point feature correspondences means more stable information (i.e. more stable to lighting condition, seasons, changes in environment etc.). Such features also lead to more compact and semantically interpretable repres

BACKGROUND: Drug-related problems due to medication errors are common and have the potential to cause harm. This study, which was conducted in Swedish primary health care, aimed to assess how well the medication lists in the medical records tally with the medications used by patients and to explore what type of medication errors are present. METHODS: We reviewed the electronic medical records (EMR
