Within this paper a simulation model of a hierarchical structure with three levels with different wireless systems is presented and investigated. The analysis is placed on a cellular level to better understand the user behavior. Modeled is a city environment, where the focus is made on the inter-system handovers between the different wireless systems and how they are affected by the change of diff
The MAX4 ring is intended to be the future user facility at MAXlab. The high-brilliance 3 GeV storage ring, equipped with small gap, short period superconducting undulators, demonstrates a high mean brilliance over a wide photon energy spectrum. The ring itself is defined from the routine operation of the small gap insertion devices, which is reflected in the small aperture of the ring magnets. Th
Dans la société contemporaine, l’accès et la dépendance accrus aux technologies numériques ont permis l'externalisation de la mémoire, ce qui représente un problème particulièrement important dans le contexte éducatif. Cet article cherche à rendre visible la façon dont les relations changent entre la recherche et la mémorisation de l'information à l’école, à partir d’une enquête menée auprès d’ens
The paper proposes a new multiple window method for estimating a peaked spectrum. The multiple windows are adapted to the signal, giving a less biased estimate for estimation of peaks than does the Thomson multiple window method. Still the result from estimation of a flat spectrum shows comparable results in variance reduction. The method is based on solution of an eigenvalue problem where the eig
Coherent operation of gate-voltage-controlled hybrid transmon qubits (gatemons) based on semiconductor nanowires was recently demonstrated. Here we experimentally investigate the anharmonicity in epitaxial InAs-Al Josephson junctions, a key parameter for their use as a qubit. Anharmonicity is found to be reduced by roughly a factor of 2 compared to conventional metallic junctions and dependent on
Overconsumption is a widely used term in science, media and among concerned consumers. What do we mean by this term? This study is based on the assumption that both the public debate on consumption and consumer research could benefit from better understanding how this term is used and from clarifying the definition. The primary aim of this study was to describe how the term 'overconsumption' is be
This essay, and the speical issue it introduces, seeks to explore leadership in a post-truth age, focusing in particular on the types of narratives and counter-narratives that characterize it and at times dominate it. We first examine the factors that are often held responsible for the rise of post-truth in politics, including the rise of relativist and postmodernist ideas, dishonest leaders and b
Using dislocation simulation approach, the basic equation for a finite crack perpendicular to and terminating at a bimaterial interface is formulated. A novel expansion method is proposed for solving the problem. The complete solution to the problem, including the explicit formulae for the T stresses ahead of the crack tip and the stress intensity factors are presented. The stress held characteris
A differential two-wire communication link with a 3-level asynchronous protocol is introduced. The proposed 3-level code contains information of both data and clock. Since only one edge is needed for each bit, the bandwidth of a link is efficiently utilized. The power consumption is reduced by the low-swing differential two-wire link and is further reduced by a 3-level code. The speed of the proto
Genes encoding the DNA helicase TWINKLE (C10orf2) or the two subunits of mtDNA polymerase γ (POLγ) (POLG1 and POLG2) have a direct effect on the mitochondrial DNA replication machinery and were reported in many mitochondrial disorders. Friedreich's ataxia (FRDA) is the common cause of ataxia often associated with the expansion of a GAA repeat in intron 1 of the frataxin gene (FXN). Mitochondrial D
The Cambrian arthropod Agnostus pisiformis (Wahlenberg, 1818) is not only a beautiful fossil animal, approximately 1 cm in length when adult, but also an extinct species unusually well-known from its ‘soft’ ventral cuticular structures. It is moreover very useful for biostratigraphic correlation and has a long research history. The species occurs in huge numbers, and in all developmental stages, i
Solar fruit drying has the potential to reduce food insecurity in developing nations. One possible technique for drying fruit is to use solar dryers. This technique is easy to use without requiring high investments. However, the drying technique can be challenging. One problem is that the drying rate could be different depending on where in the dryer the process takes place. At the beginning of th
This paper describes and analyzes the strategies and efforts of a public organization in order to establish organizational credibility in multicultural areas. The trust-building efforts by the organization, a local rescue services in the south of Sweden, are a response to several years of social unrest, communicative clashes and hostile treatment between operative firemen and residents in areas of
A simplified Fokker-Planck model for the lay-down of fibers on a conveyor belt in the production process of nonwovens is investigated. It takes into account the motion of the fiber under the influence of turbulence. The emphasis in this paper is on the development of a numerical procedure to solve the model. We present a semi-Lagrangian scheme that accurately captures the fiber dynamics and conser
