This paper explores which theorizing strategies can be employed in DSR to make a theoretical contribution by examining two illustrative case examples. First, we find that abduction, deduction, and induction all play a role in DSR. Second, we suggest that design theorists can choose among a range of theorizing strategies (i.e., inductive theorizing, deductive theorizing, and hybrid approaches) t...

The genes encoding the desulforubidin type of dissimilatory sulfite reductase (Dsr) from the sulfate-reducing bacteria Desulfobacter vibrioformis and Desulfobulbus rhabdoformis were cloned and sequenced. Similar to the genes for dissimilatory sulfite reductase from the genera Archaeoglobus, Desulfovibrio and Desulfotomaculum the dsr genes were found to form an operon, dsrABD, where dsrA and dsr...

Design Science Research (DSR) is concerned with demonstrating design principles. In order to prove the utility of these principles, design ideas are materialized into artifacts and put into an environment sufficient to host the testing of these principles. When DSR is used in combination with action research, constraints in the environment may restrain researchers to fully inscribe or test such...

Using the client device of a distributed speech recognizer usually implies the presence of background noise since most scenarios for distributed speech recognition (DSR) are situated in a non-office environment. Thus, the general task is to choose the most suitable feature extraction method for the given conditions. We present a hybrid speech recognition approach implemented for DSR that allows...

We report numerical and experimental studies of dissipative-soliton-resonance (DSR) in a fiber laser with a nonlinear optical loop mirror. The DSR pulse presents temporally a flat-top profile and a clamped peak power. Its spectrum has a rectangle profile with characteristic steep edges. It shows a unique behavior as pulse energy increases: The rectangle part of the spectrum is unchanged while t...

Mobile Ad hoc network (MANETs) are rapidly growing as an important area of wireless communication with the technological advancements in the mobile devices. Efficient routing protocols make MANETs reliable. Despite the considerable simulation works, still more investigation is required in the performance evaluation of routing protocols for multimedia traffic especially Variable Bit Rate (VBR).I...

Living Lab (LL) has been used as a milieu as well as methodology for open innovation. However, the impression of LL as a research methodology among academia is still blurring. The LL carries many elements of design science research paradigm such as innovation, artifact, evaluation, design principles, etc. however it still needs conceptual underpinning to proclaim it as a valid Design Science Re...

In this paper, we propose a media-specific forward error correction (FEC) method based on Huffman coding for distributed speech recognition (DSR). In order to mitigate the performance degradation of DSR in noisy channel environments, the importance of each subvector for the DSR system is first explored. As a result, the first subvector information for the mel-frequency cepstral coefficients (MF...

Vehicular Ad-Hoc Networks (VANETs) have recently gained considerable attention from both research and industry communities. One of the challenges posed by the study of VANETs is the definition of routing protocols design. In this paper, a realistic simulation environment is developed based on Mobility model generator for Vehicular networks (MOVE) and Network Simulator (NS2). The performance of ...

Because of several constraints in ad hoc networks, an adaptive ad hoc routing protocol is increasingly required. In this paper, we propose a synopsis of an adaptation process for an adaptive ad hoc routing protocol. Next, we put into practice the analysis of the process of adaptation to mobility by realizing an adaptive routing protocol: CSR (Cluster Source Routing) which is an extension of a w...
