In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. The system should then be able to track the positions of the fingers so that the coordinates can be mapped to the computer monitor and be
The proliferation of various data sources in urban and territorial environments has significantly facilitated the development of geospatial artificial intelligence (GeoAI) across a wide range of geospatial applications. However, geospatial data, which is inherently linked to geospatial objects, often exhibits data heterogeneity that necessitates specialized fusion and representation strategies whi
We consider waveform iterations for dynamical coupled problems, or more specifically, PDEs that interact through a lower-dimensional interface. We want to allow for the reuse of existing codes for the subproblems, called a partitioned approach. To improve computational efficiency, different and adaptive time steps in the subsolvers are advisable. Using so-called waveform iterations in combination
BackgroundMonogenic insulin resistance (IR) includes lipodystrophy and disorders of insulin signalling. We sought to assess the effects of interventions in monogenic IR, stratified by genetic aetiology.MethodsSystematic review using PubMed, MEDLINE and Embase (1 January 1987 to 23 June 2021). Studies reporting individual-level effects of pharmacologic and/or surgical interventions in monogenic IR
Power electronic converters are pivotal while designing any charging scheme, regardless of the battery capacity and application. Nowadays, Power Factor Correction (PFC) converters have become popular for various battery charging systems due to their simple configurations. Single-Ended Primary-Inductor Converter (SEPIC) and Cuk PFC converters are preferred over buck-boost converters in this regard

We consider the problem of spectral analysis of signals composed of sums of multiple amplitude modulated, possibly harmonically related, sinusoids using a sparse approach. By separating the nonlinear frequency variables using a dictionary of possible frequency components as well as a spline basis for the amplitude modulation, results in a convex criterion which can be efficiently solved without
This paper presents a constructive algorithm for memory-aware task assignment and scheduling, which is a part of the prototype system MATAS. The algorithm is well suited for image and video processing applications which have hard memory constraints as well as constraints on cost, execution time, and resource usage. Our algorithm takes into account code and data memory constraints together with the
Worries about sleep, negative expectations of sleep, and frustration about sleep loss are assumed to play an important role in the development of insomnia. Eight items designed to measure aspects of vicious cycles of sleeplessness (VCS), on which insomnia patients and controls were found to differ in an earlier study, were used to form a new VCS scale. A sleep questionnaire including the VCS scale
Popular Abstract in Swedish Avhandlingen beskriver en ny typ av kompakt röntgenkälla baserad på ett laser-producerat plasma (LPP). I motsats till konventionella LPP används inte fasta material som strålmål för den fokuserade laserstrålen. I stället används mikroskopiska vätskedroppar eller vätskestrålar. Detta medför en mycket väsentlig minskning av det skräp (debris) som skickas ut från plasmat. A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. The minute amounts of residual ionic/atomic debris can be obstructed by filters or a localized gas shield. Target liquid
This paper reports on a systematic procedure for deriving physical bounds in electromagnetic theory. The approach is based on the holomorphic properties of certain Herglotz functions and their asymptotic expansions in the low- and high-frequency regimes. A family of integral identities or summation rules is obtained with values governed by the coefficients in the low- and high-frequency expansions
