I report, emphasizing some key open issues and some aspects that are particularly relevant for phenomenology, on the status of the development of “doubly-special” relativistic (“DSR”) theories with both an observer-independent high-velocity scale and an observer-independent small-length/large-momentum scale, possibly relevant for the Planck-scale/quantum-gravity realm. I also give a true/false ...

Some classes of Deformed Special Relativity (DSR) theories are reconsidered within the Hopf algebraic formulation. For this purpose we shall explore a minimal framework of deformed Weyl–Heisenberg algebras provided by a smash product construction of DSR algebra. It is proved that this DSR algebra, which uniquely unifies κ-Minkowski spacetime coordinates with Poincaré generators, can be obtained...

Over the last two years there has been a significant research effort aimed at the development of “Doubly-Special-Relativity” (or “DSR”) theories , with contributions from about a dozen research groups . These theories of the relativistic transformations between inertial observers involve both an observer-independent large-velocity scale and an observer-independent small-length/large-momentum sc...

The focus of this research in progress is relationships between Design Science Research (DSR) on one hand, and Empirical Research (ER) on the other. More specifically, it is devoted to investigating which tasks included in a DSR project should/could require conducting ER studies or using already existing ER knowledge. The paper presents a methodology for enumerating DSR tasks and gives examples...

During the past few years there has been a discussion within the information systems community related to the similarities and differences between action research (AR) and design science research (DSR). Some believe the two research paradigms are similar and that they can be matched in ways that can improve the quality of research. Others argue that AR and DSR are based on fundamentally differe...

The Business & Information Systems Engineering (BISE) community in the Germanspeaking countries has a long track record of publishing papers using design science research (DSR). However, the state of recent DSR within the BISE community is not well documented and the lessons learned can be useful for other communities. This paper investigates the use of DSR methodology by examining articles pub...

With the advent of Wireless Application Protocol (WAP) and 2.5/3G communication systems, the mobile device has become a window to the Internet. A natural interface to this mobile device is through speech. To address this need, a new European Telecommunications Standards Institute (ETSI) standard front-end has evolved for Distributed Speech Recognition (DSR). The goal of the ETSI DSR front-end i...

In this introductory piece to the special issue on design science research (DSR) in information systems, the authors probe the past research in DSR, introduce the papers in the special issue, discuss their contributions to the field, and conclude the paper by highlighting some potential directions for future research. To provide a good overview of the research domain, the authors review the key...

Today in fast technology development in wireless mobile adhoc network there is vast scope for research. As it is known that wireless communication for mobile network has many application areas like routing services, security services etc. The mobile adhoc network is the wireless network for communication in which the mobile nodes are organized without any centralized administrator. There are ma...
