This editorial presumes that DRM patents are a public policy issue which at the end of the value chain has an impact on the consumer experience with protected digital content. After a brief general characterization of the "social invention" called patents, DRM patents are addressed and open questions are raised which deserve further analysis. Surprisingly even seemingly simple questions like th...

Mostly, current security architectures for Digital rights management (DRM) systems use either Public Key Cryptography (PKC) or Identity-based Public Key Cryptography (ID-PKC). However, PKC has a complex certificate management and ID-PKC has a key escrow problem. Certificateless Public Key Cryptography (CL-PKC) has some attractive properties which seem compatible with the requirements of DRM sys...

Environmental issues related to greenhouse gases (GHG) emissions have pushed the development of new technologies that will allow economic production low-carbon energy vectors, such as hydrogen (H2), methane (CH4) and liquid fuels. Dry reforming (DRM) has gained increased attention since it uses CH4 carbon dioxide (CO2), which are two main (GHG), feedstock for syngas, is a mixture H2 monoxide (C...

In this editorial we announce two new INDICARE deliverables: the first INDICARE consumer survey on digital music and DRM, and the first update of the INDICARE State-of-theArt-Report. In this issue you will find, apart from announcing and presenting our new findings, three articles which continue the focus we started in April on DRM in the field of scientific publishing and libraries. In further...

Subtype determination and detection of drug resistant-associated mutations (DRM) were performed on 31 HIV-1 Western blot-positive sera during the 2005 second-generation HIV surveillance in Madagascar. Amplification and sequencing of at least one of the partial reverse transcriptase, protease, and partial envelope genes were successful for all strains. All three gene sequences were obtained for ...

—In this paper, we consider a digital radio mondiale (DRM) system using orthogonal frequency division multiplexing (OFDM) with coherent detection at the receiver. The DRM pilots are two-dimensional distribution, linear interpolation and Wiener filter interpolation respectively used in the time and frequency domain as the channel estimation algorithm. We propose a low-complexity improved Wiener...
