Interference in 79 GHz Phase-Coded Automotive Radar
No full textAutomotive radars play a crucial role in the reduction of traffic casualties and the realization of autonomous driving due to its robustness and adverse weather tolerance. However, as the penetration rate of automotive radars increases, concerns arise regarding the mutual interference. In contrast to the predominant Frequency-Modulated Continuous Wave (FMCW) radars, Phase-Modulated Continuous Wave (PMCW) radars might provide solutions for the interference problem by coding the waveforms, which brings an additional degree of freedom. In this thesis, a system level overview of the phase-coded radar is presented. Regarding the popular code families, particular attention was given to the Gold, Almost Perfect Autocorrelation Sequences (APAS), and Zero-Correlation Zone (ZCZ) sequences. This thesis has proposed three distinct designs for 16-TX-element MIMO Phase-Coded radar that drives the requirements of a Medium Range Radar (MRR). The conclusion can be drawn that APAS and ZCZ sequences have shown to provide a (sub)optimal design that is emphasized by their perfect correlation characteristics within the designated distance of interest. Furthermore, in full-transmit capacity MIMO, the proposed designs use semi-orthogonal waveforms to provide excellent performance in synchronous PMCW radars. However, performance degrades in case Doppler-shifted reflections are received, whereas sidelobes arise in range due to non-orthogonality. This thesis concludes that the APAS-coded waveforms are most tolerant to Doppler shift; besides, its Time Division Multiplexing (TDM) MIMO Transmission scheme is computationally more efficient than the Code Division Multiplexing (CDM) scheme used in Gold and ZCZ coded waveforms. Finally, the radar-to-radar interference investigation has proven that for uncorrelated PMCW- to-PMCW interference, the noise floor undergoes a consistent increase, which is according to the interference-plus-noise power level calculated from the link budget analysis. This thesis emphasizes these results, as the interference effect in FMCW-to-FMCW (provided by NXP Semiconductors) have seen similar phenomena. Therefore, results in this thesis support the conclusion that coded waveforms do not remove or suppress the energy levels of the interference. For correlated interference, ghost targets might be formed, but this depends on the starting time as well as the starting coded bit of the interferer, as the correlation peak can be formed outside the distance of interest.Microwave Sensing, Signals & SystemsElectrical Engineering | Microelectronic
The people behind the papers – Dennis de Bakker, Mara Bouwman and Jeroen Bakkers
No full textUnlike mammals, adult zebrafish are capable of regenerating their hearts without scarring after injury – a process that has great therapeutic potential. A new paper in Development investigates the role of Prxx1b, a transcription factor that is expressed in epicardial heart tissue after injury, to understand its role in the scar-free regeneration of the adult zebrafish heart. To hear more about the study, we caught up with joint first authors, Dennis De Bakker and Mara Bouwman, and the corresponding author, Jeroen Bakkers, the group leader at the Hubrecht Institute and professor of Molecular Cardiogenetics at the University Medical Center in Utrecht, The Netherlands

The Quest for Citations: Drivers of Article Impact
Full text linkWhy do some articles become building blocks for future scholars, while many others remain unnoticed? We aim to answer this question by contrasting, synthesizing and simultaneously testing three scientometric perspectives – universalism, social constructivism and presentation – on the influence of article and author characteristics on article citations. To do so, we study all articles published in a sample of five major journals in marketing from 1990 to 2002 that are central to the discipline. We count the number of citations each of these articles has received and regress this count on an extensive set of characteristics of the article (i.e. article quality, article domain, title length, the use of attention grabbers and expositional clarity), and the author (i.e. author visibility and author personal promotion). We find that the number of citations an article in the marketing discipline receives, depends upon “what one says†(quality and domain), on “who says it†(author visibility and personal promotion) and not so much on “how one says it†(title length, the use of attention grabbers, and expositional clarity). Our insights contribute to the marketing literature and are relevant to scientific stakeholders, such as the management of scientific journals and individual academic scholars, as they strive to maximize citations. They are also relevant to marketing practitioners. They inform practitioners on characteristics of the academic journals in marketing and their relevance to decisions they face. On the other hand, they also raise challenges towards making our journals accessible and relevant to marketing practitioners: (1) authors visible to academics are not necessarily visible to practitioners; (2) the readability of an article may hurt academic credibility and impact, while it may be instrumental in influencing practitioners; (3) it remains questionable whether articles that academics assess to be of high quality are also managerially relevant.Impact;Citation Analysis;Referencing;Scientometrics;Cite
Hildegard de Bingen y su libro "Scivias". Ideología y conocimientos de una religiosa del siglo XII
No full textEl trabajo de Jeroen Deploige es un estudio de las fuentes bíblicas en la obra Scivias ("Conoce las vías [del Señor]") de la religiosa Hildegard de Bingen (1098-1179). En esta, su obra visionaria más conocida, así como en sus cartas y fragmentos autobiográficos, Hildegard se presenta como mujer ignorante, instruida no por los libros, sino solo por la Ciencia Divina, que la instruye en la interioridad de su alma y le hace ver y escuchar lo que ella escribe en sus obras. En su artículo, Deploige (autor de un libro recientemente publicado sobre Hildegard) muestra que al menos las lecturas bíblicas de esta escritora no se diferenciaban de las de los grandes autores masculinos de su siglo.
Jeroen Deploige's work is a study of bíblical sources in "Scivias" (Know thee the ways [of the Lord] by the religious writer Hildegard de Bingen (1098-1179). In this, her best known visionary work, as in her letters and autobiographical fragments, Hildegard presents herself as an ignorant woman, instructed not by books, but by Divine Science, which instructs her in her innermost self, and permits her to see and hear that which she writes down in her works. In his article, Deploige (author of a recently published book on Hildegard) shows that at the least, the biblical readings of this writer did not differ from those of the great masculine writers of her century
Doe de tienkamp: gebiedshistorie en identiteit bij duurzame gebiedsontwikkeling
No full textDuurzame gebiedsontwikkeling is vooral succesvol als de ontwikkelaars rekening houden met de identiteit en de culturele context van het gebied. Dat stellen onderzoekers Leo Oorschot en Jeroen Mensink in dit nieuwe hoofdstuk van de Tienkamp voor duurzame gebiedsontwikkeling. Zij leggen uit hoe je die identiteit en context bepaalt en laten zien hoe dit in de praktijk uitpakt van de gemeente Amsterdam.Over ‘Doe de tienkamp!’Dit jaar publiceert de leerstoel gebiedsontwikkeling van de TU Delft een update van ‘Doe de tienkamp!’ uit 2011.

Heretyk Jeroen i jego ekrany. Refleksje o pewnej wystawie multimedialnej
No full textHeretic Jeroen and his screens The article presents the multimedia binding of the many years’ project “Jheronimus Bosch 500”, which led — in the jubilee year — to developing the monographic exhibition of Hieronymus Bosch’s works in Hertogenbosch 2016. According to the author of the article Internet seems to be a useful “megaarchives” for works of art and for some important events organized because of them. It is useful especially for collecting and exposing film documentation of interpretation of the works, their con-servation and creating marketing strategies which make the artist a so-called glocalbrand hero. The documentation of some film events of the project in Hertogenbosch is presented on the page https://www.youtube.com/channel/UCh9n1lmat4buzWzjqJaDfMA/videos. We can find there a collection of documents and quasi-documents, some films of didactic and persuasive cinema, but also some marketing products, of which role is to cause selling the constellation of events of the project. Avoiding the rating of the substantive value of the mentioned objects, the author of the article shows that the portals YouTube or Vimeo are sometimes the only, and sometimes not too orderly, open film archive of associating of people with art.

Methods Explained: Multilevel network meta-regression
No full textFor this edition of “Methods Explained,” I have spoken to 2 experts who play an important role in the adoption of multilevel network meta-regression (ML-NMR) in the field of health economics and outcomes research (HEOR). Jeroen Jansen, PhD is an Associate Professor at the Department of Clinical Pharmacy of the University of California, San Francisco and Chief Scientist, HEOR at the Precision Medicine Group. Drawing on methods used in ecology, Jeroen first introduced a precursor to ML-NMR back in 2012. David Phillippo, PhD is a Research Fellow in Evidence Synthesis at the Bristol Medical School of the University of Bristol. David generalized Jeroen’s ideas into the ML-NMR framework and is the author of the multinma R package, which is playing an important role in the broader adoption of ML-NMR
Flood planning; the politics of water security
No full textFloods are amongst the most common and devastating natural disasters. In the wake of such an event, the pressure to initiate flood protection schemes that will provide security is enormous, and politicians promise quick solutions in the national interest. Jeroen Warner examines a number of such projects from around the world - the Middle East, South Asia and Western Europe - aimed at the prevention of serious flooding. Each provoked a level of controversy unforeseen by its initiators, with the result that schemes were shelved, were not completed, or simply failed. The author shows how such projects inevitably become politicized as different stakeholders seek to promote their interests
