The interior stress problem is solved numerically for a single-edge notched specimen under uniaxial load. The algorithm is based on a modification of a Fredholm second-kind integral equation with compact operators due to Muskhelishvili. Several singular basis functions for each of the seven corners in the geometry enable high uniform resolution of the stress field with a modest number of discretiz
Gaia is ESA’s space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS). A core part of AGIS
In this paper power system security is estimated with a linear support vector machine (SVM). The SVM is used to calculate a hyperplane which separate states of the power system that sustain an (n-1) fault from states that do not. The hyperplane can be used on-line in order to determine if the system is moving into insecure conditions. The proposed method is developed to support operators at contro
Ioannes Dantiscus' letters are a source of singular importance for 16th century European history. Dantiscus was a great traveller who got first-hand information from most parts of Europe, and his correspondence conveys to us today a vivid and varied picture of Early Modern Europe. The list of his correspondents is a name-dropper's dream: Copernicus, Philip Melanchton and Hernan Cortez, to mention
Somatic rearrangements contribute to the mutagenized landscape of cancer genomes. Here, we systematically interrogated rearrangements in 560 breast cancers by using a piecewise constant fitting approach. We identified 33 hotspots of large (>100 kb) tandem duplications, a mutational signature associated with homologous-recombination-repair deficiency. Notably, these tandem-duplication hotspots were
The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at sNN=5.02 TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward (−4.46 < ycms < −2.96) and forward (2.03 < ycms < 3.53) rapidity regions, corresponding to Pb-going and p-going directions, respectively. The Z-boson production cross section, with dimuon invariant mas
Popular Abstract in Swedish Vi tänker oss i allmänhet att vår upplevelse av drömmen är lik vår upplevelse av vår vakna verklighet i så måtto att drömmen presenterar sig som en värld som vi som drömmare tar för verklig och som vi på olika sätt interagerar med. I denna avhandling tittar jag närmare på denna uppfattning och granskar hur väl den harmonierar med vad vi nu anser oss veta om hur hjärnan/This treatise examines what I call the ‘traditional view’ on the phenomenology of dreaming. According to this view, dreams are experienced in more or less the same way as waking reality – that is, our experience of “being-in-the-dream” is very much like our experience of “being-in-the-world”. The traditional view will be examined from three different standpoints: phenomenology, cognitive science a
It is a well known fact that since the 1960s, Sweden and Holland have developed completely different types of drug policy. But there are a number of misconceptions as to what the differences consist in and how they have arisen. My contribution to this anthology involves elucidating these differences. In the context of international discussions of drug policy, the policies followed by Sweden and Ho
Sweden does not have a legal definition of small and medium-sized enterprises (SMEs). There are, however, special tax rules which apply to unquoted companies and close companies. A "close company" is defined in the statutes as a company or an economic association in which a small number of people, directly or indirectly, own shares representing more than 50% of the voting rights. Close companies a
A low-noise amplifier (LNA) and mixer circuit in 0.35-mum CMOS operates at 2.1 GHz. Merging the LNA and mixer lowers the number of transistors in the signal path and thereby also the nonlinearity and power consumption. The circuit meets the specifications for a direct conversion wide-band code-division multiple access (WCDMA) receiver. Its noise figure is 3.4 dB (5 kHz to 5 MHz), the total convers
The dominating models of information processes have been based on symbolic representations of information and knowledge. During the last decades, a varietyof non-symbolic models have been proposed as superior. The prime examples of models within the non-symbolic approach are neural networks. However, to a large extent theylac k a higher-level theoryof representation. In this paper, conceptual spac
Dion–Jacobson (DJ) type 2D perovskites with a single organic cation layer exhibit a narrower distance between two adjacent inorganic layers compared to the corresponding Ruddlesden–Popper perovskites, which facilitates interlayer charge transport. However, the internal crystal structures in 2D DJ perovskites remain elusive. Herein, in a p-xylylenediamine (PDMA)-based DJ perovskite bearing bifuncti
Food accessibility has been an important issue for as long as there has been human civilisation. Today, food, at least in the wealthier parts of the world, is accessible to most people. However, there are concerns regarding the market power of major retailers and the availability of affordable food among certain population groups. In this paper, I investigate how well accessibility, the ease with
The process of protein crystallization from aqueous protein solutions is still insufficiently understood. During macroscopic crystal formation, occurring often on time scales from a few hours to several days, protein dynamics evolves on the molecular level. Here, we present a proof of concept and a framework to observe this evolving diffusive dynamics on the pico- to nanosecond time scale, associa
Introduction: Accurate discharge summaries counteract drug-related problems due to insufficient information transfer in care transitions, but require optimal transfer and use. Careful follow-up is often essential after hospital discharge, for example when it comes to pain management in elderly patients; a common and challenging task in primary care. Aims: To assess the transfer and use of the disc
In this paper, we propose a gridless method for estimating an unknown number of fundamental frequencies. Starting with a conventional dictionary matrix, containing sets of candidate fundamental frequencies and their corresponding harmonics, a non-convex log-sum cost function is formed such that it imposes the harmonic structure and treats every fundamental frequency in the dictionary as a paramete
