Modern analytical workloads are highly heterogeneous and massively complex, making generic query optimizers untenable for many customers and scenarios. As a result, it is important to specialize these optimizers to instances of the workloads. In this

Modern database management systems employ sophisticated query optimization techniques that enable the generation of efficient plans for queries over very large data sets. A variety of other applications also process large data sets, but cannot levera

Modern DNA sequencing technology produces large volumes of genome strings for various biological and medical applications. To mitigate the space overhead required for storing these genome data, previous research has developed compression schemes to s

Analytic queries enable sophisticated large-scale data analysis within many commercial, scientific and medical domains today. Data skew is a ubiquitous feature of these real-world domains, but current systems do not make the most of caches for exploi

Network communication is the slowest component of many operators in distributed parallel databases deployed for large-scale analytics. Whereas considerable work has focused on speeding up databases on modern hardware, communication reduction has rece

This paper proposes a novel method for cartoon-style modelling and simulation of water coupled with static or dynamic objects. For the coupling with static objects, we specially design a main wave splitting algorithm, making the simulation results mo

The air distribution characteristics formed by an “air curtain” ventilation approach are investigated in detail. The airflow visualization and full-scale experimental results of air distribution in an occupied zone are reported in this paper. The
