Cellular-based localization and sensing pave the way for a variety ofapplications across various domains, ranging from autonomous driv-ing to emergency care and intelligent traffic management. Althoughtraditional methods have been effective, they still face challenges such as therequirement for highly accurate models and the inherent complexity of thealgorithms. This thesis explores the potential
High-order harmonic generation (HHG) supplies extreme ultraviolet (XUV) radiation with attosecond pulse duration for a wide variety of applications from fundamental research to industry. As HHG is a very inefficient process, enhancing the XUV flux is of great interest. Hereby, either the HHG process itself or the laser which is the primary driver of HHG can be optimized.Currently, the technology i
Unmanned aerial vehicles (UAVs) have been widely used in both military and civilian applications, where a stable communication link is vital for safe flight control and robust data transmission. To develop a reliable UAV communication system, it is necessary to deeply understand the UAV channel characteristics and establish accurate channel models. Channel sounding is the most effective way to obt
Electrons from a laser wakefield accelerator have a limited energy gain due to dephasing and are prone to emittance growth, causing a large divergence. In this paper, we experimentally show that adjusting the plasma density profile can address both issues. Shock-assisted ionisation injection is used to produce 100 MeV quasi-monoenergetic electron bunches in the primary part of the accelerator. Dow
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of vestibular stimulation compared to standard care or non-vestibular stimulation for physical and neurological development in preterm infants. To assess whether the effects of vestibular stimulation differ according to gestational age at birth; the type, frequency,
In this study, we present the initial results from a long-term initiative to develop a multi-millennial tree-ring width (TRW) chronology for subfossil oak (Quercus spp.) trees in South Scandinavia. We have constructed 40 TRW chronologies, primarily from oak trunks extracted from peatlands, archaeological sites, drainage ditches, and infrastructure projects, as well as some submerged material. The
for clarinet, bassoon, horn and trumpetImpossible colors is not a hypothesis, but rather more hyperbole. In this musical piece "impossible colors" refer to illusions of timbre in sound, not vision. Impossible colors are colors that we do not normally see; that some fictional colors are beyond the functional perceptual space of humans. Some theories looking at forbidden colors, borrowed from color
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of infant positioning, nesting, and swaddling for promoting development and preventing morbidity in preterm infants.
The Vimmerby Moraine is the only significant ice-marginal moraine on the eastern side of southern Sweden, but no detailed studies exist on its formation during the final deglaciation of the Fennoscandian Ice Sheet. Through ground-penetrating radar surveys and detailed sediment logging, we provide evidence for an active, oscillating ice margin during the formation of the Vimmerby Moraine, suggestin
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of multisensory stimulation compared to any single sensory intervention or standard care for physical and neurological development in preterm infants.
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To evaluate the benefits and harms of olfactory stimulation with different odorants in the NICU for promoting development and preventing morbidity in preterm infants.
It is intuitive and well known, that if agents in a multi-agent system iteratively update their states in the Euclidean space as convex combinations of neighbors’ states, all states eventually converge to the same value (consensus), provided the interaction graph is sufficiently connected. However, this seems to be also true in practice if the convex combinations of states are mapped or radially p
Deterministic lateral displacement (DLD) and related microfluidic sorting devices are typically evaluated based on the size distributions of particles collected at each outlet, even though the more relevant measure of performance is the probability that a particle of a given size ends up in a specific outlet. Here, we use Bayes’ rule to infer these size-dependent routing probabilities from experim
Although the Chinese government claims respect of human rights, it seems that the official Chinese conception of these rights is not only different from but also challenges the dominant international conception - this Chinese challenge of the international human rights regime constitutes the problem area of this thesis. Using a Laclau and Mouffe inspired discourse analysis strategy to deconstruct
This paper presents a neural network based semantic plane detection method utilizing polygon representations. The method can for example be used to solve room layout estimations tasks and is built on, combines and further develops several different modules from previous research. The network takes an RGB image and estimates a wireframe as well as a feature space using an hourglass backbone. From t
To complete a new Swedish railway line in a much shorter timeframe than today, alter natives to the traditional methods need to be explored. One option is the use of prefabricated concrete slabs elevated on piers, analogous to the concept used in China for building new railways in record time (He et al., 2017). The method has the advantage of directly tackling the barrier effects exhibited by trad
