A combined method for evaluating criteria when selecting ERP systems
There are many benefits offered by integrated enterprise computer systems. There are a growing number of options available to obtain such management information system support. A major problem when selecting Enterprise Information Systems, in special ERP systems, is how to deal with the great diversity of options as well as the number of criteria used to evaluate each alternative. There is an impl
Fair routing and related optimization problems - invited talk
Routing of elastic traffic in the Internet should be fair in terms of bandwidth allocated to individual traffic demands. One fairness principle that can be applied is called max-min fairness (MMF) and requires that the worst bandwidth allocation is maximized and the solution is then extended with maximization of the second worst allocation, the third one, and so on. In this paper we discuss soluti
Analysis of Self-Pressurization Phenomenon in a Cryogenic Fluid Storage Tank With VOF Method
The self-pressurization phenomenon is studied numerically with the Volume of Fluid (VOF) method in a cryogenic fluid tank. Heat and mass transfer modelling is used for the phase change calculation at the interface. Transient simulations of the vaporization and pressure rise in a cylindrical liquid hydrogen tank are performed. The computations are carried out by using the CFD software package, Ansy
Recent changes in the global and regional carbon cycle: analysis of first-order diagnostics
TECHNOLOGICAL ADVANCES IN HYBRID IMAGING AND IMPACT ON DOSE.
New imaging technologies utilising X-rays and radiopharmaceuticals have developed rapidly. Clinical application of computed tomography (CT) has revolutionised medical imaging and plays an enormous role in medical care. Due to technical improvements, spatial, contrast and temporal resolutions have continuously improved. In spite of significant reduction of CT doses during recent years, CT is still
Versatile in situ powder X-ray diffraction cells for solid-gas investigations
This paper describes new sample cells and techniques for in situ powder X-ray diffraction specifically designed for gas absorption studies up to ca 300 bar (1 bar = 100 000 Pa) gas pressure. The cells are for multipurpose use, in particular the study of solid-gas reactions in dosing or flow mode, but can also handle samples involved in solid-liquid-gas studies. The sample can be loaded into a sing
Support of Neuronal Growth Over Glial Growth and Guidance of Optic Nerve Axons by Vertical Nanowire Arrays.
Neural cultures are very useful in neuroscience, providing simpler and better controlled systems than the in vivo situation. Neural tissue contains two main cell types, neurons and glia, and interactions between these are essential for appropriate neuronal development. In neural cultures, glial cells tend to overgrow neurons, limiting the access to neuronal interrogation. There is therefore a pres
A numerical study of the effects of stresses induced by moisture gradients in steel-to-timber dowel joints
This experimental study examines the influence of moisture variations on the load-bearing capacity of steel-timber dowel joints. The glulam specimens used to manufacture the joints were first exposed to controlled climate changes. After being stored in the climate chambers, holes were drilled and dowels were inserted. Then, the joints were loaded to failure. The main aim of this study was to inves

Impact of comorbidity on family genetic risk profiles for psychiatric and substance use disorders : A descriptive analysis
Background - Comorbidity between psychiatric disorders is extensive but, from a genetic perspective, still poorly understood. Modern molecular genetic approaches to this problem are limited by a reliance on case-control designs. Methods - In 5 828 760 individuals born in Sweden from 1932-1995 with a mean (s.d.) age at follow-up of 54.4 (18.1), we examined family genetic risk score (FGRS) profiles
Local Routing in Sparse and Lightweight Geometric Graphs
Online routing in a planar embedded graph is central to a number of fields and has been studied extensively in the literature. For most planar graphs no O(1)-competitive online routing algorithm exists. A notable exception is the Delaunay triangulation for which Bose and Morin (SIAM J Comput 33(4):937–951, 2004) showed that there exists an online routing algorithm that is O(1)-competitive. However
Fish avoid visually noisy environments where prey targeting is reduced
The environment contains different forms of ecological noise that can reduce the ability of animals to detect information. Here, we ask whether animals adapt their behavior to either exploit or avoid areas of their environment with increased dynamic visual noise. Threespined sticklebacks (Gasterosteus aculeatus) were immersed in environments with a simulated formof naturally occurring visual noise
Formal Modelling Approaches to Complexity Science in Roman Studies : A Manifesto
Complexity science refers to the theoretical research perspectives and the formal modelling tools designed to study complex systems. A complex system consists of separate entities interacting following a set of (often simple) rules that collectively give rise to unexpected patterns featuring vastly different properties than the entities that produced them. In recent years a number of case studies
A side-channel attack on a masked IND-CCA secure saber KEM implementation
In this paper, we present a side-channel attack on a first-order masked implementation of IND-CCA secure Saber KEM. We show how to recover both the session key and the long-term secret key from 24 traces using a deep neural network created at the profiling stage. The proposed message recovery approach learns a higher-order model directly, without explicitly extracting random masks at each executio

Floodplain mapping using hydraulic simulation model in GIS
In this research, a methodology was applied to integrate hydraulic simulation model, HEC-RAS and GIS analysis for delineation of flood extents and depths within a selected reach of Zaremroud River in Iran. Floodplain modeling is a recently new and applied method in river engineering discipline and is essential for prediction of flood hazards. It is necessary to simulate complicated hydraulic behav

Effective interactions in protein-salt solutions approaching liquid-liquid phase separation
We present an experimental study combined with a theoretical discussion of the effective interactions in protein solutions approaching a liquid-liquid phase separation (LLPS) induced by addition of multivalent metal ions. The reduced second virial coefficient, B2/B2HS, is used to describe the interaction and discussed with theoretical predictions for colloidal systems. We have determined the salt
