Trust Anchors in Software Defined Networks

Advances in software virtualization and network processing lead to increasing network softwarization. Software network elements running on commodity platforms replace or complement hardware components in cloud and mobile network infrastructure. However, such commodity platforms have a large attack surface and often lack granular control and tight integration of the underlying hardware and software

In vivo high field myelin water imaging: Investigating the T2 distribution at 7T

With the increased frequency of human 7T scanners, there is also a drive towards the implementation advanced MR sequences, such a myelin water imaging, at high fields. Here, we demonstrate the feasibility of translating 3T myelin acquisitions scheme, GRASE, to 7T. We studied the distribution of T values at 7T and determined that myelin water has a T

A Novel Capacitive Sensor Based on Molecularly Imprinted Nanoparticles as Recognition Elements

Molecularly Imprinted Polymers (MIPs) are synthetic receptors capable of selective binding to their target (template) molecules and, hence, are used as recognition elements in assays and sensors as a replacement for relatively unstable enzymes and antibodies. Herein, we describe a manufacturing-friendly protocol for integration of MIP nanoparticles (nanoMIPs) with a (label-free) capacitive sensor.

Influence of Microstructure and Surface Roughness on Fatigue Initiation in Extruded Aluminum

Comprehensive experimental data on the fatigue properties of extruded Al6082-T6 is used together with crystal plasticity simulations to investigate the microstructure and surface roughness influence on fatigue initiation. Thesurface roughness of the specimens used in the experiments was mapped with White Light Interferometry (WLI) and the location of the fatigue initiation sites was identified and

Pressurised liquid extraction of persistent organic pollutants in environmental analysis

This review updates our knowledge on pressurised liquid extraction, PLE (also known as accelerated solvent extraction and pressurised fluid extraction) of persistent organic pollutants such as polynuclear aromatic hydrocarbons and polychlorinated biphenyls from environmental matrices. The basic experimental set-up is presented, and parameters influencing the extraction process are discussed. PLE c

Social Class and Excess Mortality in Sweden During the 1918 Influenza Pandemic

There is no consensus in the literature about the role of socioeconomic factors on influenza mortality during the 1918 pandemic. While some scholars have found that social factors were important, others have not. In this study, we analyzed differences in excess mortality by social class in Sweden during the 1918 pandemic. We analyzed individual-level mortality of the entire population aged 30–59,

The Berkeley Innovation Index: : A Quantitative Approach to Measure, Track and Forecast Innovation Capability Within Individuals and Organizations

Innovation and entrepreneurship are essential processes for human development, market growth, and technological breakthroughs, and it is vital for economic growth. Despite its importance, innovation is inherently difficult to measure and hence it is almost impossible for an individual or organization to know how they can improve their innovation output or claim that they are great at innovation. T

Estimating the hindered-settling flux function from a batch test in a cone

The hindered-settling velocity function for the modelling, simulation and control of secondary settling tanks can be determined from batch tests. The conventional method is to measure the velocity of the descending sludge-supernatant interface (sludge blanket) as the change in height over time in a vessel with constant cross-sectional area. Each such experiment provides one point on the flux curve

Generation of hydroxyl radicals from reactions between a dimethoxyhydroquinone and iron oxide nanoparticles

The hydroxyl radical (·OH) is a powerful oxidant that is produced in a wide range of environments via the Fenton reaction (Fe2+ + H2O2 → Fe3+ + ·OH + OH-). The reactants are formed from the reduction of Fe3+ and O2, which may be promoted by organic reductants, such as hydroquinones. The aim of this study was to investigate the extent of ·OH formation in reactions between 2,6-dimethoxyhydroquinone

Industrial Practices in Security Vulnerability Management for IoT Systems – an Interview Study

The area of Internet of Things (IoT) is growing and it affects a large amount of users, which means that security is important. Many parts of IoT systems are built with Open Source Software, for which security vulnerabilities are available. It is important to update the software when vulnerabilities are detected, but it is unclear to what extent this is done in industry today. This study presents

Effect of the engine calibration parameters on gasoline partially premixed combustion performance and emissions compared to conventional diesel combustion in a light-duty Euro 6 engine

A design of experiments analysis was performed to investigate the effects of pilot quantity, combustion phasing and exhaust gas recirculation on performance and emissions in a gasoline partially premixed combustion to find out the optimal combination of the all varied parameters. The experimental activities were performed on a light-duty Volvo Euro 6 diesel engine. The test was performed under ste
