Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN , a fram
A fully integrated instrument for cereal grain quality assessment is presented. Color video images of grains fed onto a belt are digitized. These images are then segmented into kernel entities, which are subject to the analysis. The number of degrees of freedom for each such object is decreased to a suitable level for Artificial Neural Network (ANN) processing. Feed- forward ANN's with one hidden
Purpose: The purpose of this paper is to investigate the thermal performance of the cooling plates with conventional straight channel and wavy channel designs. Design/methodology/approach: A three-dimensional model involving coupled fluid flow and heat transfer processes is developed to study the thermal performance of the cooling plates. The effects of wavelength and amplitude on the cooling perf
Vid tiden för Göteborgs 400-årsjubileum var ordet trygghet på många av göteborgarnas läppar. Göteborgs Stad hade sedan några år inlett ett tydligt fokus på att försöka öka invånarnas trygghet genom projekt som ”Trygg i Göteborg” och genom polisiära insatser för att minska den organiserade brottsligheten. Med tanke på sådana insatser tedde det sig kanske inte underligt att hela 15 procent av de sva
Lignin is one of the main components of plant cell walls, which provides mechanical support for plants and also contributes to resisting against plant pathogenic fungi. In the fruit industry, the lignin content can affect the quality of fruit. The biosynthesis of lignin involves a variety of enzymes, of which caffeoyl-CoA 3-O-methyltransferase (CCoAOMT) is a class of methyltransferases that plays
Achieving a robust ignition with minimal spark plug wear is challenging in heavy duty engines fueled with gaseous fuels like biogas and hydrogen. Thermal energy deposition from the spark to the gas was studied in a 10.9 milliliter custom-built spark calorimeter. An AC capacitive ignition system was used along with a dual-nickel standard J-gap spark plug and the influence of multiple physical and e
Purpose: to propose two enhancements for the European Union’s Circular Material Use rate (CMU): inclusion of Preparation for Reuse (PfR) flows and enhanced reproducibility across lower levels of analysis. Methods: PfR flows are added to the material flow Sankey Diagram. The Local Circularity Rate (LCR) is based in the CMU and is broke down in three waste-related ratios: recovered-to-treated (RCV-t
e consider waveform iterations for dynamic coupled problems with respect to therole of time window length. We review existing theoretical results about the error of waveformiterations and the role of the time window length. Furthermore, we present numerical resultsfor waveform iterations with both time adaptive sub solvers and with fixed time steps. Thisway, we are able to give a recommendation on
Energy is essential for the sustenance of life. The energy and economy of any nation are interlinked—energy demand is generally proportional to the economic growth of the nation. In the present era, renewable energy (RE) is the primary area of interest to save fossil fuels, achieve sustainability, and reducing carbon emissions, as well as other gases in the atmosphere that create climatic problems
Externally bonded fiber-reinforced polymer (FRP) plates or sheets have become a common retrofitting approach for sustaining old reinforced concrete structures in the modern era. The capacity of FRP-strengthened structures cannot be accurately estimated because the bond strength between FRP and concrete surface is accurately unpredictable. Various studies are available in the literature to predict
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system caused by myelin-specific autoreactive T cells. We previously demonstrated intestinal barrier disruption and signs of inflammation in experimental autoimmune encephalomyelitis (EAE), a model of MS. Fecal calprotectin is a disease activity biomarker in inflammatory bowel diseases, released by neutrophils
