Sommario/riassunto |
|
Subband adaptive filtering is rapidly becoming one of the most effective techniques for reducing computational complexity and improving the convergence rate of algorithms in adaptive signal processing applications. This book provides an introductory, yet extensive guide on the theory of various subband adaptive filtering techniques. For beginners, the authors discuss the basic principles that underlie the design and implementation of subband adaptive filters. For advanced readers, a comprehensive coverage of recent developments, such as multiband tap-weight adaptation, delayless architectures, |

Sommario/riassunto |

"Denne antologien belyser ulike forskningsetiske aspekter ved interessekonflikter i forskning, og reiser grunnleggende spørsmål om forskningens rolle i samfunnet. I løpet av de siste årene har forskere og andre i flere tilfeller uttrykt bekymring over hvordan forskning styres og brukes av politiske og økonomiske interesser, der forskningsresultater trekkes i tvil, og der det fremmes anklager om fusk eller dårlig kvalitet. «Interessekonflikter» er et begrep fra forskningsetikken som kan bidra til å avklare hva som står på spill i mange av disse sakene. Spørsmål som tas opp i antologien, inkluderer: Hva er egentlig interessekonflikter i forskning? Er idealet om interesseløshet realistisk? I hvilken grad kan åpenhet bøte på utfordringene knyttet til interessekonflikter? Målet er at tekstene i denne boken skal bidra til refleksjon og debatt om de etiske prinsippene og normene som skal verne om forskningens kvalitet og troverdighet. Antologien henvender seg til forskere og en bredere offentlighet som er opptatt av forskningsetiske spørsmål. Bidragsyterne er forskere, hovedsakelig innenfor naturvitenskapelige og teknologiske fag." |
"This anthology examines various ethical issues related to conflicts of |

interest in research and raises fundamental questions about the role of research in society. In recent years, researchers and others have expressed concern on several occasions about how research has been conducted or used for political or economic gain, where outcomes of research have been called into question and accusations of rigging or poor quality have been leveled. "Conflict of interest" is a term from research ethics that can help clarify what is at the core of many of these cases. Questions posed and explored in this anthology include: What exactly is a conflict of interest within the context of research? Is the ideal of pure, unbiased objectivity even realistic? To what degree can transparency remediate challenges associated with conflicts of interest? The objective with this collection of chapters is to encourage reflection and discourse about the ethical principles and norms that insure quality and integrity in research. The anthology will be of interest to researchers in particular, and all others concerned with ethics in research." |
