Persistent Protection in Multicast Content Delivery Malek Barhoush, Ph.D. Concordia University, 2012 Computer networks make it easy to distribute digital media at low cost. Digital rights management (DRM) systems are designed to limit the access that paying subscribers (and non-paying intruders) have to these digital media. However, current DRM systems are tied to unicast delivery mechanisms, w...

Very high throughput satellite (VHTS) systems are expected to have a large increase in traffic demand the near future. However, this will not be uniform throughout service area due nonuniform user distribution, and changing during day. This problem is addressed using flexible payload architectures, enabling allocation of resources manner meet each beam, leading dynamic resource management (DRM)...

Very high throughput satellite (VHTS) systems are expected to have a huge increase in traffic demand the near future. Nevertheless, this will not be uniform over entire service area due non-uniform distribution of users and changes during day. This problem is addressed by using flexible payload architectures, which allow allocation resources flexibly meet each beam, leading dynamic resource man...

A NiMgGa-layered double hydroxide (NMG-LDH) is synthesized as an efficient catalyst precursor for dry reforming of methane (DRM). NMG-LDH converted to intermetallic Ni3Ga/MgO upon reduction. Compared a monometallic Ni/MgO prepared from NiMg-LDH, the exhibits high CH4 (∼48%) and CO2 (∼52%) conversions well excellent stability against coking during DRM. The reversible phase transition between Ni3...

Using deep neural networks to solve PDEs has attracted a lot of attentions recently. However, why the learning method works is falling far behind its empirical success. In this paper, we provide rigorous numerical analysis on Ritz (DRM) \cite{wan11} for second order elliptic equations with Neumann boundary conditions. We establish first nonasymptotic convergence rate in $H^1$ norm DRM using $\m...

We propose LicenseScript, a language for digital rights management (DRM) based on multiset rewriting and logic programming. LicenseScript enjoys a precise syntax and semantics, and it is rich enough to embed other rights expression languages (REL). We show that LicenseScript is expressive and flexible by exploring several application domains representing different aspects of DRM. We present an ...
