2. 1. Real-time data stream clustering over sliding windows

   Author : Sobhan Badiozamany; Tore Risch; Tamer Özsu; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data streaming; Sliding windows; Clustering; ; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : In many applications, e.g. urban traffic monitoring, stock trading, and industrial sensor data monitoring, clustering algorithms are applied on data streams in real-time to find current patterns. Here, sliding windows are commonly used as they capture concept drift. READ MORE

4. 2. Spark Plasma Sintering Enhancing Grain Sliding, Deformation and Grain Size Control : Studies of the Systems Ti, Ti/TiB2, Na0.5 K0.5 NbO3, and Hydroxyapatite

   Author : Mirva Eriksson; Zhijian Shen; Takashi Goto; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spark plasma sintering; plastic deformation; grain growth; titanium; TiB2; hydroxyapatite; Na0.5K0.5NbO3; ferroelectric; transparent; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

   Abstract : The unique features of the Spark plasma sintering (SPS) were used to investigate the sintering and deformation behaviour of titanium and titanium–titanium diboride composites, and to control the sintering and grain growth of ferroelectric Na0.5K0.5NbO3 (NKN) and of hydroxyapatite (HAp).

5. 3. Reconfigurable-Hardware Accelerated Stream Aggregation

   Author : Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream; Reconfigurable Computing; Aggregation; Dataflow; FPGA; Memory Hierarchy; Compression;

   Abstract : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. READ MORE

6. 4. Long-Term Stable Communication in Centrally Scheduled Low-Power Wireless Networks

   Author : Oliver Harms; Christian-Albrechts-Universität zu Kiel; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronous Transmissions; IEEE 802.15.4; WSN; Opportunistic Routing; Time-Slotted Channel Hopping TSCH ; Industrial Internet of Things; Routing; Central Scheduling; Wireless Sensor-Actuator Networks; IoT;

   Abstract : With the emergence of the Internet of Things (IoT), more devices are connected than ever before. Most of these communicate wirelessly, forming Wireless Sensor Networks. In recent years, there has been a shift from personal networks, like Smart Home, to industrial networks. READ MORE

7. 5. The Potential of b-value Variations as Earthquake Precursors for Small and Large Events

   Author : Paiboon Nuannin; Roland Roberts; Ota Kulhanek; Bjorn Lund; Federico Guendel; Uppsala universitet; []
   Keywords : General; Frequency magnitude distribution; b-values; rockbursts; Andaman-Sumatra region; Zinkgruvan mine; December 26; 2004 earthquake; ALLMÄNT;

   Abstract : The potential of variations of b-values in the G-R relation, logN=a-bM as earthquake precursors for small events (rockbursts) in Zinkgruvan mine, Sweden and for tectonic (large) earthquakes in the Andaman-Sumatra region were investigated. The temporal frequency-magnitude distribution, b(t), of rockbursts in Zinkgruvan mine was examined using high quality data recorded during the period November 1996 to April 2004 with magnitude ranges from Mw= -2.
