Efficient Delivery Policy to Minimize User Traffic Consumption in Guaranteed Advertising
Jia Zhang, Zheng Wang, Qian Li +4
In this work, we study the guaranteed delivery model which is widely used in online display advertising. In the guaranteed delivery scenario, ad exposures (which are also called im…
Reduced storage nodal discontinuous Galerkin methods on semi-structured prismatic meshes
Jesse Chan, Zheng Wang, Russell J. Hewett +1
We present a high order time-domain nodal discontinuous Galerkin method for wave problems on hybrid meshes consisting of both wedge and tetrahedral elements. We allow for verticall…
Bayesian inverse problems with priors: a Randomize-then-Optimize approach
Zheng Wang, Johnathan M. Bardsley, Antti Solonen +2
Prior distributions for Bayesian inference that rely on the -norm of the parameters are of considerable interest, in part because they promote parameter fields with less regul…
Does Your DNS Recursion Really Time Out as Intended? A Timeout Vulnerability of DNS Recursive Servers
Zheng Wang
Parallelization is featured by DNS recursive servers to do time-consuming recursions on behalf on clients. As common DNS configurations, recursive servers should allow a reasonable…
Modeling and Predicting DNS Server Load
Zheng Wang
The DNS relies on caching to ensure high scalability and good performance. In optimizing caching, TTL adjustment provides a means of balancing between query load and TTL-dependent…
Combating Malicious DNS Tunnel
Zheng Wang
This paper proposes a defense scheme against malicious use of DNS tunnel. A tunnel validator is designed to provide trustworthy tunnel-aware defensive recursive service. In additio…
