Stefan Larssons kapitel placerar in dagens artificiella intelligens (AI) i sin digitala samtidshistoriska kontext — relationen till plattformar och internet som nätverk — och fördjupar därefter bilden av de mänskliga farhågorna med autonoma teknologier. Stefan visar på samspelet mellan databeroende AI och samhällets värderingar, och lyfter fram några av de demokratiska utmaningar som följer i kölv
To make autonomous, affordable ships feasible in the real world, they must be capable of safely navigating without fully relying on GPS, high-resolution 3D maps, or high-performance navigation sensors. We suggest a method for estimating the position using affordable navigation sensors (compass and speed log or inertial navigation sensor), sensors used for perception of the environment (cameras, ec
We present a new type of wireless access infrastructure consisting of a fabric of dispersed electronic circuits and antennas that collectively function as a massive, distributed antenna array. We have chosen to name this new wireless infrastructure 'RadioWeaves' and anticipate they can be integrated into indoor and outdoor walls, furniture, and other objects, rendering them a natural part of the e
Introduction: Whether data on International Classification of Diseases (ICD)-codes from the Swedish National Patient Register (NPR) correctly correspond to subtypes of inflammatory bowel disease (IBD) and phenotypes of the Montreal classification scheme among patients with prevalent disease is unknown.Materials and methods: We obtained information on IBD subtypes and phenotypes from the medical re
The machinability of brass is considered to increase with the addition of lead as an alloying element. Due to both environmental and health reasons, the decrease of lead in brass components is of high importance. Several mechanical and thermal material properties control a materials machinability, in combination with the chosen machining system. To evaluate the difference in machinability between
Modelling of tool wear in metal cutting processes has been the foundation of the field since the famous Taylor's tool life model. Tool wear models have been developed for planning machining operations and calculating production costs. Most wear models do not include wear rate in the model but rather just the final wear at end of tool life, i.e. the limiting wear. This is a major disadvantage of Ta
BACKGROUND AND AIMS: Capsule endoscopy (CE) has revolutionized small-bowel (SB) investigation. Computational methods can enhance diagnostic yield (DY); however, incorporating machine learning algorithms (MLAs) into CE reading is difficult as large amounts of image annotations are required for training. Current databases lack graphic annotations of pathologies and cannot be used. A novel database,
A protective coating is often used on the cladding of wooden facades to limit the absorption of moisture. Low wood moisture content (MC) is essential to obtain satisfactory durability performance. Wood density is known to influence the water sorption and crack formation of uncoated wood. However, the effect of density on the aforementioned behaviors of coated spruce is not yet fully understood. Si
Background: The optimal way of pacing in patients with an indication for pacing and concomitant first-degree atrioventricular (AV)–block is not known, and consequently, firm guidelines on this topic are lacking. This study explored the current pacemaker programming pattern in patients with first-degree AV-block who have a dual chamber pacemaker without cardiac resynchronization. Methods: The study
Rapporten handlar om civilsamhällets ledare och bygger på en enkätundersökning som genomfördes under hösten 2017 med 140 ledare för nationella och regionala organisationer i det civila samhället i Sverige (N. 140). Syftet med rapporten är att ge en bred bild av dessa ledares positioner, de resurser de förfogar över, deras aktiviteter och inflytande, deras erfarenheter kring ledarskap och motiv til
Contrary to the general trend in European countries since the 2000s, Sweden has neither restricted its migration policy nor limited the rights of migrants. This changed with the ‘refugee crisis’ of 2015 when the government introduced policy changes to curb the number of arrivals and impede the granting of residence permits. Civil society organizations are significantly involved in the reception of
In recent years, it has been recognized that the seismic wave equation solved with a finite-difference method in time causes a predictable and removable error through the use of so-called time-dispersion transforms. These transforms were thought not to apply to visco-elastic media. However, in this paper we demonstrate that the time-dispersion transforms remain applicable when the visco-elastic wa
Signal apparition is a recent signal processing advance that has numerous applications in seismic data acquisition and processing. In this paper we review the basic principles of signal apparition and discuss applications related to simultaneous source acquisition. We discuss the generalization of the technique to large number of sources and the application in a full 3D configuration enabling larg
