    Abstract : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. READ MORE

  4. 7. Understanding Test-Artifact Quality in Software Engineering

    Author : Huynh Khanh Vi Tran; Nauman bin Ali; Jürgen Börstler; Michael Unterkalmsteiner; Blekinge Tekniska Högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Software testing; Test case quality; Test suite quality; Test artifact quality; Quality assurance; Programvaruteknik; Software Engineering;

    Abstract : Context: The core of software testing is test artifacts, i.e., test cases, test suites, test scripts, test code, test specifications, and natural language tests. Hence, the quality of test artifacts can negatively or positively impact the reliability of the software testing process. READ MORE

  5. 8. Text Mining The Quality Paradigm(s)

    Author : Daniel Carnerud; Ingela Bäckström; Kristen Snyder; Ton van der Wiele; Mittuniversitetet; []

    Abstract : The purpose of this thesis orbits around an examination of the formation of a quality paradigm. In this inquiry, the exploration and application of text mining have been used to provide new insights into quality as a paradigm. READ MORE

  6. 9. Traffic Management in Software-Defined Data Center Networks

    Author : Cristian Hernandez Benet; Andreas Kassler; Boris Koldehofe; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; SDN; data center; load-balancing; traffic management; EVPN; big data; programmable data plane; Computer Science; Datavetenskap;

    Abstract : Traffic management in data centers is paramount to improving network and application performance, thereby improving the quality of service by reducing network congestion, packet loss, and latency. However, the deployment and configuration of traffic management techniques are challenging due to diverse data-center traffic characteristics, large data center topologies, and the interplay of different protocols at the routing, transport, and link layer.
