2. 1. Digital Marketing Strategy : B2B and Stakeholders Communication

   Author : Maryam Lashgari; Klaus Solberg Søilen; Stefan Stieglitz; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital Media; Proximity Marketing; Beacon Technology; Social Media; Industriell ekonomi och organisation; Industrial Economics and Management; Media Technology; Medieteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Since digital media entered the business domain, many different tools and platforms have transformed the nature of business communications. This transformation has not been easy, since the journey has been accompanied by challenges from the marketers’ side against the adoption of the new platforms into the firm’s communication channels.

4. 2. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels

   Author : Naga Vishnukanth Irukulapati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viterbi algorithm; fiber-optic channel; stochastic digital backpropagation; performance limits; factor graphs; near-MAP detector; Digital backpropagation; nonlinear compensation; mutual information;

   Abstract : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. READ MORE

5. 3. Superconductor Digital Signal Processor

   Author : Irina Kataeva; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid Single Flux Quantum logic RSFQ ; multiuser detector; VHDL; Multiply-Accumulate Unit; Successive Interference Canceller;

   Abstract : Superconductor digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times gain in speed and more than 100 reduction in power consumption over mainstream CMOS devices. However, the necessity of cooling down to 4 K and modest degree of integration density currently available mean that employing RSFQ is reasonable only for the tasks that are impossible or ineffective to implement in CMOS technology.

6. 4. Digital Rights Management - the New Copyright

   Author : Kristoffer Schollin; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Copyright; IT-law; Intellectual property; Digital rights management; DRM; TPM;

   Abstract : DRM – DIGITAL RIGHTS MANAGEMENT is a wide term that covers many forms of technological schemes for controlling access, use and distribution of creative works – from the blunt and static restrictions on copy-protected Compact Discs to the sophisticated and fluid usage-rules in online music- and movie-stores such as iTunes. DRM technologies have been created and designed in response to a social development where global, digital networks are putting serious pressure on traditional distribution channels. READ MORE

7. 5. Open Quantum Systems : Effects in Interferometry, Quantum Computation, and Adiabatic Evolution

   Author : Johan Åberg; Erik Sjöqvist; Sten Lunell; Vlatko Vedral; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Open Systems; Completely Positive Maps; Channels; Decoherence; Quantum Information; Quantum Computing; Adiabatic Approximation; Quantum Search; Time-Complexity; Fysik; Physics; Fysik;

   Abstract : The effects of open system evolution on single particle interferometry, quantum computation, and the adiabatic approximation are investigated.Single particle interferometry: Three concepts concerning completely positive maps (CPMs) and trace preserving CPMs (channels), named subspace preserving (SP) CPMs, subspace local channels, and gluing of CPMs, are introduced.
