Preparation of mullite-TiB2-CNTs hybrid composite through spark plasma sintering
Ceramics International, 2019A near fully dense mullite-TiB2-CNTs hybrid composite was prepared successfully trough spark plasma sintering. 1 wt%CNT and 10 wt%TiB2 were mixed with nano-sized mullite powders using a high energy mixer mill.

Proceedings of the ACM SIGAda annual international conference on Ada and related technologies, 2009
Level -Intermediate SPARK is an annotated sub-language of Ada which is unambiguous and suitable for rigorous static analysis. It has been extensively used in industrial applications where safety and security are paramount, such as miltary aerospace, rail signaling, and high-grade cryptographic systems.

As the diversity of novel architectures expands rapidly there is a growing interest in studying the behavior of these architectures for computations arising in different applications. There has been significant efforts in evaluating the performance of supercomputers on typical dense computations, and several packages for this purpose have been ...

2016In this work, we present and examine ways for a more efficient run of theta joins in a Spark system which extends the MapReduce programming model. Specifically, we focus on the optimization of the percentage of the communication cost, which occurs by performing theta joins in a Spark system and on the efficiency of the workload, which is affected by ...

Proceedings of the 2007 ACM SIGMOD international conference on Management of data, 2007
With the increasing amount of text data stored in relational databases, there is a demand for RDBMS to support keyword queries over text data. As a search result is often assembled from multiple relational tables, traditional IR-style ranking and query evaluation methods cannot be applied directly.
