Purpose of this paper The purpose of this paper is to examine how logistics performance is affected by the use of different identification technologies and practices for utilising the tracking data. Design/methodology/approach The paper uses the survey method. The survey instrument was developed in co-operation with an expert group consisting of both researchers and industry representatives. The

Growth models of charged nanoplatelets are investigated with Monte Carlo simulations and simple theory. In a first model, 2-dimensional simulations in the canonical ensemble are used to demonstrate that the growth of a single weakly charged platelet could be limited by its own internal repulsion. The short range attractive interaction in the crystal is modeled with a square well potential while th

Rituell glömska gäller individen eller institutionen, som står inför Gud eller inför människor. Där ritualen erbjuder individen glömska inför Gud, kan skulden och straffet inför människor stå kvar. Detta tydliggörs i Strindbergs Påsk. I den romersk.katolska kyrkan är prästens fullmakt att avlösa inte, som i Svenska kkyrkan, given med prästvigningen, utan delegerad. Under högmedeltiden började man

In an attempt to bridge the material and pressure gaps - two major challenges for an atomic scale understanding of heterogeneous catalysis - we employed high-energy surface X-ray diffraction as a tool to study the Pd(553) surface in situ under changing reaction conditions during CO oxidation. The diffraction patterns recorded under CO rich reaction conditions are characteristic for the metallic st

Research on the role of nutrition in type 2 diabetes has largely focused on macro/micronutrient composition and dietary fiber intake, while fewer studies have tested the effects of differing food choice. Some observational studies and short-term intervention studies suggest that a food pattern mimicking the diet with which humans evolved positively influences glucose control and associated endocri

Processed food and eating out of the home are increasing phenomena, which presents new business opportunities for food manufacturers. However, the new food products require increased quality and safety, and thereby a more controlled distribution. The overall purpose of the research presented in this article is to describe the food supply chain from a critical context point of view in order to high

We study a generalized Pólya urn model with two types of ball. If the drawn ball is red, it is replaced together with a black ball, but if the drawn ball is black it is replaced and a red ball is thrown out of the urn. When only black balls remain, the roles of the colors are swapped and the process restarts. We prove that the resulting Markov chain is transient but that if we throw out a ball eve

The article treats freemasonry as an integrated part of sociability among European military elites.

Popular Abstract in Swedish Introduktion: Validitet handlar enkelt uttryckt om överensstämmelse med sanningen eller exempelvis om ett instrument mäter det som är avsett. Validitet kan också ses som ett mer komplext begrepp, innefattande aspekter som nytta, relevans, värderingar och sociala konsekvenser. Validitet förutsätter reliabilitet som är ett mått på tillförlitlighet, noggrannhet eller reproAbstract Introduction: Validity is important at different levels in psychiatry. Valid structured instruments are important aids in screening and diagnostics, in both research and clinical practice. An aim of the diagnostic procedure is to yield valid diagnoses. Ultimately, the validity of structured instruments (non-empirical) and clinical diagnoses depends on the validity of the diagnostic class

Two methylcelluloses (MC) were investigated by partial hydrolysis followed by direct infusion electrospray ionisation mass spectrometry (ESI-MS). Partial hydrolysis was achieved either enzymatically or by acid hydrolysis. Enzyme hydrolysis was performed using the endoglucanase Bacillus agaradhaerens Cel 5a. Three different hydrolysis buffer solutions were investigated in order to deter-mine which

The computation of the Capon and the amplitude and phase estimation (APES) filters can be very time consuming. The burden lies not only in the inversion of the sample covariance matrix, but also in the matrix multiplications. In this paper, we propose an efficient algorithm for the computation of the above mentioned filters, using Cholesky factorization and fast Fourier transforms. Furthermore, we

Recurrent major depressive disorder with regular seasonal patterns, commonly known as seasonal affective disorder (SAD), has evoked substantial research in the last two decades. It is now recognised that SAD is a common condition with prevalence rates between 0.4% and 2.9% of the general population, and that patients with SAD experience significant morbidity and impairment in psychosocial function

Functional data analysis is used to examine articulatory variability across repetitions in normal speech, under different movement constraints. A temporal normalization technique is applied to align trajectories of lips, jaw, and tongue in vowel-consonant-vowel sequences. Next, an index of amplitude variability is computed, defined as the mean standard deviation between peak velocities of the cons
