3. 2. Efficient Data Streaming Analytic Designs for Parallel and Distributed Processing

   Författare :Hannaneh Najdataei; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stream processing; continuous analysis; scalability; elasticity;

   Sammanfattning : Today, ubiquitously sensing technologies enable inter-connection of physical objects, as part of Internet of Things (IoT), and provide massive amounts of data streams. In such scenarios, the demand for timely analysis has resulted in a shift of data processing paradigms towards continuous, parallel, and multitier computing. LÄS MER

4. 3. Nanotribology, Surface Interactions and Characterization : An AFM Study

   Författare :Rubén Álvarez-Asencio; Mark W. Rutland; Suzanne Giasson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

   Sammanfattning : When two surfaces achieve contact, then contact phenomena such as adhesion, friction and wear can occur, which are of great interest in many disciplines, including physics, physical chemistry, material chemistry, and life and health sciences. These phenomena are largely determined by the nature and magnitude of the surface forces such as van der Waals, capillary and hydration forces. LÄS MER
