2. 1. Development and Implementation of a Wireless Sensor Network for Volcanic Gas Emission Monitoring

   Author : Yan Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NOVAC; gas emission; sensor; embedded PC; volcano; DOAS; spectroscopy; SO2; network;

   Abstract : Volcanic eruptions have great impacts on the life of the inhabitants in the surrounding areas and even to the global climate. Around 15-21×10 Tg/yr SO2 are injected to the troposphere and the stratosphere by the active volcanoes in the world[Halmer et al., 2002]. 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. Public Key Infrastructure and its applications for resource-constrained IoT

   Abstract : In today's society, more and more embedded computer systems are connecting. There are many different types of embedded systems including industrial networks, Internet of Things (IoT), distributed control systems, connected vehicles, etc. READ MORE

7. 5. Multifaceted Defense Against Distributed Denial of Service Attacks: Prevention, Detection, Mitigation

   Author : Zhang Fu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Network Security; Overlay; Distributed Denial-of-Service; System Design; DDoS Detection; Distributed Computing;

   Abstract : Distributed Denial of Service (DDoS) attacks can be so powerful that they can easily deplete the computing resources or bandwidth of the potential targets, by flooding massive packets. Internet infrastructures and network applications, including social services and communication systems for emergency management, are under the threat of the DDoS problem. READ MORE
