2. 1. Reliable and deterministic network services

   Author : Florian-Daniel Otel; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

   Abstract : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. READ MORE

4. 2. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures

   Author : Ezzeldin Shereen; György Dán; Joe H. Chow; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor measurements unit; Time synchronization; Power system state estimation; Network Security; Time synchronization attacks; Precision time protocol; Machine learning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. READ MORE

5. 3. Network-based Anomaly Detection for SCADA Systems : Traffic Generation and Modeling

   Author : Chih-Yuan Lin; Simin Nadjm-Tehrani; Mikael Asplund; Aditya P. Mathur; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open standards and being connected to the Internet to enable remote control. READ MORE

6. 4. Large scale integration and interactive exploration of cancer data – with applications to glioblastoma

   Author : Patrik Johansson; Sven Nelander; Rebecka Jörnsten; Lene Uhrbom; Gary Bader; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Glioblastoma; data integration; network modeling; interactive exploration; precision medicine; Oncology; Onkologi; Molekylär medicin; Molecular Medicine; Statistics; Statistik;

   Abstract : Glioblastoma is the most common malignant brain tumor, with a median survival of approximately 15 months. The standard of care treatment consists of surgical resection followed by radiotherapy and chemotherapy, where chemotherapy only prolongs survival by approximately 3 months. READ MORE

7. 5. Risk and Vulnerability Analysis of Interdependent Technical Infrastructures: Addressing Socio-Technical Systems
