This paper reviews means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabilit

Intermittently administered PTH is known to increase bone mass in osteoporosis models. We studied its effects in bone repair and implant fixation, using histological and mechanical techniques in rats. In a bone chamber, PTH substantially increased the density of the new-formed bone, whereas there was only a minor effect on the pre-existing bone in the L5 vertebra or femur. Considering that PTH inc

The study examines a hitherto neglected genre in Swedish poetry of the 17th and 18th centuries: the animal epitaph. From 1670 to 1760 a considerable number of such poems were composed by several of the leading poets of the day. Besides tracing the history of the genre back to its origins in the ancient Greek epigram, I am chiefly concerned with the functions that the writing of such epigrams had i

In this paper we investigate some properties of the union bound for a basic MIMO system, assuming uncoded QAM transmission, uncorrelated Rayleigh fading, and maximum likelihood detection. The presented union bound results cover several choices of the number of transmitting and receiving antennas (up to 16). It is also illustrated how the pair-wise error probability approaches the Q( )-function as

In this paper a non-line-of-sight (NLOS) path-loss and fading model developed for vehicle-to-vehicle (V2V) communication at 5:9 GHz is validated with independent and realistic measurement data. The reference NLOS model is claimed to be flexible and of low complexity, and incorporates specific geometric aspects in a closed-form expression.We validated the accuracy of the model with the help of real

Popular Abstract in Swedish Bakgrund Coeliaki eller glutenenteropati (GE) är beteckningar på ett så kallat malabsorptionstillstånd, dvs ett tillstånd med brister (som kan omfatta bl a B-vitaminer, järn och kalk) och/eller diarré till följd av inflammation i tarmen. Vid GE sitter inflammationen i slemhinnan i början av tunntarmen. GE omnämndes första gången av Araeteus i Rom 2:a århundradet efter The prevalence of coeliac disease (CD) was initially estimated to 1/1537. Based on serial analysis [GA and endomysial antibodies (EMA)], the prevalence was 6/1970 (0.30%). In autoimmune chronic hepatitis 5.4% and in IDDM 2.6% had CD, why regular screening for CD in these conditions seems motivated. The frequency of IgA-GA positivity was increased in alcoholic liver disease, PBC, primary sclerosin

Basic statistics courses for engineering students often focus on general applications in engineering, using course literature intended for ‘engineers’. However, these students are not a homogeneous group, and the differences among engineering programmes appear to be increasing. One way to meet the challenge of the diversity of needs within a discipline is to adapt the courses for different program

The monotone rearrrangement algorithm was introduced by Hardy, Littlewood and Po ́lya as a sorting device for functions. As- suming that x is a monotone function and that an estimate xn of x is given, consider the monotone rearrangement xˆn of xn. This new estimator is shown to be uniformly consistent. Under suitable as- sumptions, pointwise limit distribution results for xˆn are obtained. The fra

A new architecture for Discrete Fourier Transform (DFT) based channel estimation has been analyzed, implemented and synthesized for ASIC. The core concept of the proposed esti- mation algorithm is to process the channel increments rather than the channel coefficients. With strong enough time correlation, we can reduce the wordlength of processing blocks compared to standard channel estimators and
