Given a sequence of numbers (Formula presented.) in [0, 1], consider the following experiment. First, we flip a fair coin and then, at step n, we turn the coin over to the other side with probability (Formula presented.), (Formula presented.), independently of the sequence of the previous terms. What can we say about the distribution of the empirical frequency of heads as (Formula presented.)? We

We extend a thermodynamically consistent finite strain micro-sphere framework elaborated by Carol et al. towards the modelling of phase-transformations to allow for the simulation of polycrystalline solids such as, e.g., shape memory alloys and shape memory polymers undergoing large deformations. The considered phase-transformation mechanism is based on statistical physics and allows the considera

We propose a signal-to-noise criterion which predicts whether a feature of a given size and scattering strength, placed inside a larger object, can be retrieved with two common X-ray imaging techniques: coherent diffraction imaging and projection microscopy. This criterion, based on how efficiently these techniques detect the scattered photons and validated through simulations, shows in general th

We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different measurement campaigns (four indoor scenarios and one outdoor scenario). We observe that the received power, th

Academics are becoming accustomed to growing demands on ‘performance’ as universities place increasing emphasis on quantifiable research outputs. Despite the rapid ascendancy of bibliometrics, limited empirical research has considered the definitions of “research performance” employed by institutions, and subsequent academic responses. Drawing on exploratory data collected from 58 university-based

We measured absolute cross sections for neutron transfer channels populated in the Rb94+Pb208 binary reaction. Cross sections have been extracted identifying directly the lead isotopes with the high efficiency MINIBALL γ-ray array coupled to a particle detector combined with a radioactive Rb94 beam delivered at Elab=6.2 MeV/nucleon by the HIE-ISOLDE facility. We observed sizable cross sections in

Artikeln kompletterar två tidigare texter i tidskriften Ale 2020: 2–3 om Lyngsjö i Skåne. Elisabeth Reuterswärd söker här bakgrunden till dopfuntens ovanliga motiv, medan Sten Skansjö förklarar utvecklingen i socknen över tid. Denna artikel uppmärksammar, att dopfunten har spår av bemålning, kommenterar kyrkans herrskapsgalleri, korrigerar upplysningarna om antalet gyllene altare i Norden, visar aThe article presents a supplement to two earlier texts in the periodical Ale 2020: 2–3 on Lyngsjö in Scania. Elisabeth Reuterswärd here seeks the background for the unusual motif of the baptismal font, where Sten Skansjö tries to explain the development in the parish over time. The present article draws attention to the fact that the font has traces of painting, comments on the upper gallery of th

Particulate matter emission factors from vehicle brakes are difficult to assess directly from the field. Moreover, there is a lack of a standardized cycle and test stand for evaluating brake emissions. For these reasons, a test cycle was developed from real driving data collected from a car. This new test cycle was implemented on an inertia disc brake dynamometer appositely designed for brake part
