The prints of J.N. Darling
No full textThis is the bibliographic record of the book entitled The Prints of J.N. Darling by Amy N. Worthen that is in the NCTC Conservation Library collection. J.N. "Ding" Darling is an extraordinary example of the artist at work in conservation education. After he guided the funding for the Migratory Bird Hunting Stamp Act through Congress, Ding Darling sketched his concept of a suitable image for the First Federal Duck Stamp.

Bouwen met de natuur
No full textEerste plan van Svasek voor een kustuitbreiding tussen Hoek van Holland en Scheveningen, gebruikmakend van natuurlijke processsen. In dit document is voor het eerst de term "bouwen met de natuur" (building with nature") gebruikt. " De hier gepresenteerde beschouwingen hebben als doel een bijdrage te leveren aan de thans opgeleefde diskussie over de kustlokaties als onderdeel van de regionale en provinciale ruimtelijke ordening. Gepoogd is om van het begin af aan het natuurgebeuren ten grondslag te leggen aan de planning. De kennis van de kustmorfologie is in Nederland in voldoende mate aanwezig om bij het ontwerpen van kustplannen met de natuur en niet tegen de natuur in te kunnen werken.

The Rossiter-McLaughlin effect for exoplanets
No full textThere are now more than 30 stars with transiting planets for which the stellar obliquity—or more precisely its sky projection—has been measured, via the eponymous effect of Rossiter and McLaughlin. The history of these measurements is intriguing. For 8 years a case was gradually building that the orbits of hot Jupiters are always well-aligned with the rotation of their parent stars. Then in a sudden reversal, many misaligned systems were found, and it now seems that even retrograde systems are not uncommon. I review the measurement technique underlying these discoveries, the patterns that have emerged from the data, and the implications for theories of planet formation and migration
Characterization of a Compton camera setup with monolithic LaBr<sub>3</sub>(Ce) absorber and segmented GAGG scatter detectors
No full textThe purpose of this study is to perform a first characterization and proof of principle investigation of a Compton camera setup composed by a scatterer component consisting of a pixelated GAGG crystal read out by a SiPM multi-pixel photon counter (MPPC) and an absorber component consisting of a monolithic LaBr3 (Ce) scintillator read out by a 256-fold multianode photomultiplier (PMT). The rationale of the study is to develop a Compton camera system as a future ion beam range verification device during particle therapy, via prompt gamma imaging. The properties to be investigated are the reconstruction efficiency and accuracy achievable with this system for detecting prompt-\gamma rays. The Compton camera system described has been tested with a laboratory radioactive Cesium137 source, in a certain geometrical configuration. The readout system is based on individual spectroscopy (NIM+VME) electronic modules, digitizing energy and time signals. The data have been analyzed to produce an input for the image reconstruction, performed using the MEGAlib toolkit software.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.RST/Medical Physics & Technolog

On the energy concentration factor in a binary magnonic crystal - Presentazione poster
No full textA quantitative estimation of the degree of localization of collective modes in binary magnonic crystals (BMCs) is given by recalling the definition of the energy concentration factor (CFPHC) in a photonic crystal (PHC) [1,2] [1]J.D.

Wafer-level packaging technology for RF applications based on a rigid low-loss spacer substrate
No full textAs mobile portable devices such as cellular system/phones, smart handheld devices and laptop computers acquire wireless connectivity there is a growing demand for greater levels of RF integration. The holy grail of integration is to have a whole set of different components integrated into one chip. However, for RF front-end the problem is the passive device integration. Moreover, protection of noise-sensitive analog circuits from "noisy" digital circuits becomes increasingly difficult for highly integrated components. To meet these challenges new enabling packaging technologies may be considered. The cost of wireless communications systems is often quoted as a most important driver. Thus, wafer-level packaging (WLP) may be considered as a promising solution to cost-effective RF system manufacturing, due to substantial cost savings with WLP's massively parallel processing and testing potential. In this thesis a wafer-level packaging concept based on a rigid spacer technology is proposed, that addresses both the issue of high-Q passive device integration and of on-chip isolation.Electrical Engineering, Mathematics and Computer Scienc
