The separation of multiple transmit waveforms with time and frequency synchronization constitutes a considerable challenge for multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) systems. It is well-known that aliased signal returns may be separable by digital beamforming (DBF) on receive in elevation. However, the current orthogonal-waveform beamforming schemes significantly incr
Objective: To assess the reliability of speech data and speech-related quality indicators in the Swedish quality registry for cleft lip and palate (CLP) at 10 years of age. Design: Retrospective study. Setting: University hospitals. Participants: One hundred twenty-one 10-year-olds with unilateral or bilateral CLP. Main outcome measures: Six independent raters reassessed audio recordings for compa
Remote monitoring of cognition holds the promise to facilitate case-finding in clinical care and the individual detection of cognitive impairment in clinical and research settings. In the context of Alzheimer’s disease, this is particularly relevant for patients who seek medical advice due to memory problems. Here, we develop a remote digital memory composite (RDMC) score from an unsupervised remo
Despite the clear restrictive guidelines about the use of modern handheld devices among children younger than 2 years, parents are seen to extensively use these devices with their infants. However, parents’ perceptions in this regard remain unclear and underexplored especially, in the context of South Asian cultures such as Pakistan. This qualitative study aims to explore parents’ perceptions rega
Since the turn of the millennium, the appointment of women judges has increased markedly in Africa and the Middle East, along with the social and political influence of courts. The expansion of judicial power worldwide raises important questions about who the judges are and what their role should be. The appointment of women to positions of judicial authority has increased, but this increase is on
“There is something to confess: your speaker likes to leave a movie theater. Back out on the more or less empty, more or less brightly lit sidewalk (it is invariably at night, and during the week, that he goes), and heading uncertainly for some café or other, he walks in silence (he doesn’t like discussing the film he’s just seen), a little dazed, wrapped up in himself…”In his 1975 essay, Leaving
In most genres of fiction representations of a profession, discipline or calling must broadly resonate with the conceptions of that role held by audiences. But very few represenations of PR practice to be found in novels written by UK-based writers draw a picture of PR activity that sits comfortably with the ”idealised” models offered by organisations such as the Chartered Institute of Public Re
Popular Abstract in Swedish Trä är ett konstruktionsmaterial med många positiva egenskaper, både avseende mekaniska och tekniska egenskaper och avseende det som ibland kallas mjuka egenskaper. Trä har generellt hög styrka i förhållande till sin vikt, det är ett naturligt förnybart material och det anses av många vara estetiskt tilltalande. Jämfört med andra vanliga konstruktionsmaterial som stål oThis thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. The theoretical parts concern development of two models for strength and fracture analysis, both based on fracture mechanics approaches, and their application to analysis of beams with a hole and d
New robot applications increasingly require external sensing to accomplish robustness and performance despite the variations and uncertainties that come with the increasing demands on flexibility for manufacturing of customized products. The demands on productivity then require high performance, which for well known feedback-control reasons means short response times from external process event to
Purpose: Allogeneic hematopoietic stem cell transplantation (HSCT) is an intensive curative treatment that increases family caregivers’ burden. The aim of this study was to explore the feasibility of remotely assessing and addressing family caregivers’ support needs in terms of demand and acceptability using the Carer Support Needs Assessment Tool Intervention (CSNAT-I) in the HSCT context. Method
Computer-vision-based gaze estimation refers to techniques that estimate gaze direction directly from video recordings of the eyes or face without the need for an eye tracker. Although many such methods exist, their validation is often found in the technical literature (e.g., computer science conference papers). We aimed to (1) identify which computer-vision-based gaze estimation methods are usabl
We examine whether exposure to gender inequality at export destinations affects the gender wage gap in exporting firms. We motivate the analysis through a stylized model where wages depend on worker productivity, and men have a comparative advantage when trading with gender-unequal countries due to customer discrimination. Empirically, we use high-quality matched employer-employee data from Sweden
Popular Abstract in Swedish Antagandet att människor är förmögna att kontrollera och avsiktligt glömma oönskade minnen har varit kontroversiellt allt sedan Freud (1915/2000) först antog den typen av psykologisk process. Men aktuell experimentell forskning ger ökat belägg för att avsiktligt undertryckande av oönskade minnen faktiskt kan leda till senare glömska (cf. Levy & Anderson, 2002). ResuForgetting can be highly functional when unwanted or irrelevant memory representations interfere with cognitive or motivational goals. Current theory assumes that forgetting can be brought about by the intentional or unintentional inhibition of interfering memory representations. In four studies, the present thesis investigated this claim by employing behavioral testing, and neuroimaging methods b
In this paper, we investigate the impact of power amplifier (PA) nonlinear distortion in pre-coded multi-user large antenna or massive MIMO downlink systems. First, detailed signal and system models are derived for the received signal at single-antenna user equipment (UE) under channel-aware linear precoding in the base-station combined with behavioral models for the individual PA units, covering
Popular Abstract in Swedish Antalet människor som insjuknar i cancer (cancerincidensen) runtom i världen ökar, exempelvis i Sverige har antalet diagnosticerade tumörer ökat med i snitt 2.1% per år de senaste 20 åren. Denna ökning förklaras bland annat av vår ökade livslängd och vårt val av livsstil. Trots detta har antalet människor som dör i cancer minskat de senaste 20 åren. Dessa motsägelsefullThe continual increase in incidence of cancer has created an urgent need for improved methods for diagnosis, prognosis and/or treatment. In this context, the field of biomarker research has expanded immensely during the last few years. This thesis, based on four original papers, revolves around protein biomarker discovery in cancer. For this purpose, an in-house design recombinant antibody microar
This thesis explores the application of Henri Lefebvre’s theory of the social production of space to the analysis of Malmö University more specifically Orkanen, the name of one of the two main buildings of the university. With a particular focus on how conceived, perceived, and lived spaces interact within the university’s neoliberal context. Through a combination of Schwarze’s operationalization
The 4th Industrial Revolution provides a window of opportunity for the developing world and in particular, Sub-Saharan Africa to catch-up in terms of social and economic development by enhancing growth through technological advances. At the same time, it bears the risk for Sub-Saharan Africa to fall even further behind if technological advances cannot be absorbed into the region’s economies. Altho
At Tetra Pak, general knowledge of food and beverage processing is of great importance. This in turn, depends on the equipment used for the particular process. One of these equipment consists of deformed tubes made of stainless steel 316L. The aim of the present work is to get an understanding of the material 316L. To achieve this, physical tensile tests are performed to study the material behavio
