1. 16. Streaming Aggregation using Reconfigurable Hardware

   Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming; Aggregation; Dataflow; FPGA;

   Sammanfattning : High throughput and low latency streaming aggregation is essential for many applications that analyze massive volumes of data in real-time. In many cases, high speed stream aggregation can be achieved incrementally by computing partial results for multiple windows. LÄS MER

3. 17. Chemical Mechanical Polishing of Silicon and Silicon Dioxide in Front End Processing

   Författare :Markus Forsberg; Jörgen Olsson; Jyrki Molarius; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; chemical mechanical polishing; chemical mechanical planarization; silicon; silicon dioxide; front end; shallow trench isolation; deep trench isolation; bipolar transistor; BiCMOS; wafer bonding; Elektronik; Electronics; Elektronik;

   Sammanfattning : Chemical mechanical polishing (CMP) has been used for a long time in the manufacturing of prime silicon wafers for the IC industry. Lately, other substrates, such as silicon-on-insulator has become in use which requires a greater control of the silicon CMP process. LÄS MER

4. 18. Regulation of gene expression in the vascular wall

   Författare :Erik Larsson; Göteborgs universitet; []
   Nyckelord :smooth muscle; endothelium; angiogenesis; SRF; myocardin; LPP; gene regulation; genetics; microRNA;

   Sammanfattning : Blood vessel growth and function are closely related to a number of pathological conditions, including tumor angiogenesis, wound healing and atherosclerosis. Smooth muscle cells (SMC) and endothelial cells (EC), the two major constituents of the vascular wall, are both characterized by the expression of unique phenotypic marker genes, many of which have vital roles in blood vessel development and disease.

5. 19. Efficient Memory Access and Synchronization in NoC-based Many-core Processors

   Författare :Xiaowen Chen; Zhonghai Lu; Umit Ogras; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Many-core; Network-on-Chip; Distributed Shared Memory; Microcode; Virtual-to-physical Address Translation; Memory Access Fairness; Barrier Synchronization; Cooperative Communication; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : In NoC-based many-core processors, memory subsystem and synchronization mechanism are always the two important design aspects, since mining parallelism and pursuing higher performance require not only optimized memory management but also efficient synchronization mechanism. Therefore, we are motivated to research on efficient memory access and synchronization in three topics, namely, efficient on-chip memory organization, fair shared memory access, and efficient many-core synchronization.

7. 20. Engineering ferroelectric domains and charge transport by proton exchange in lithium niobate

   Författare :Michele Manzo; Katia Gallo; Marin Alexe; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium niobate; Ferroelectrics; Teknisk materialvetenskap; Materials Science and Engineering; Fysik; Physics;

   Sammanfattning : Ferroelectrics are dielectric materials possessing a switchable spontaneous polarization, which have attracted a growing interest for a broad variety of applications such as ferroelectric lithography, artificial photosynthesis, random and dynamic access memories (FeRAMs and DRAM), but also for the fabrication of devices for nonlinear optics, etc. All the aforementioned applications rely on the control of the ferroelectric domains arrangement, or the charge distribution and transport.
