    Reflecting on the role of emotions in the PhD process

    No full text
    This research project examined the role of emotions in the PhD process through an exploratory, qualitative, self reflective study by six recent or current PhD candidates. Despite differences in the nature of the PhD fields of study, and in the personal backgrounds of the participants, a number of common themes were recognised. We developed an interactive workshop for postgraduate students in which participants were asked to reflect on their emotional experiences in their own studies. The combined information from these sources was used to suggest some strategies for management of negative emotions that may arise during the PhD process. Of critical importance is the multiple roles of the PhD supervisor in helping manage the negative emotions that most PhD students inevitably experience at some stage in their candidature. Most important, though, is the role of self reflection in identifying potential emotional problems and their solutions; a process we recommend to PhD candidates and supervisors

    A 0.25mm<sup>2</sup> Resistor-Based Temperature Sensor with an Inaccuracy of 0.12°C (3σ) from -55°C to 125°C and a Resolution FOM of 32fJK<sup>2</sup>

    Temperature sensors based on Wheatstone bridges, e.g. [1,2], have recently achieved higher resolution and greater energy efficiency than conventional BJT-based sensors [3]. However, this comes at the expense of area, making them less attractive in industrial applications. This paper presents a Wheatstone-bridge sensor that uses a zoom-ADC architecture to reduce area (by 3x over [2]) and achieve state-of-the-art energy-efficiency for an integrated temperature sensor. After a 1st-order fit and a systematic non-linearity correction [2,4], it also achieves state-of-the-art inaccuracy: 0.12°C (3σ) over the full military temperature range (-55°C to 125°C).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.Electronic InstrumentationMicroelectronic

    A CMOS Dual-RC frequency reference with ±250ppm inaccuracy from -45°C to 85°C

    No full text
    To comply with wired communication standards such as USB, SATA and PCI/PCI-E, systems-on-chip require frequency references with better than 300ppm accuracy. LC-based references achieve 100ppm accuracy [1], but suffer from high power consumption (∼20mW). Thermal diffusivity (TD) references require less power (∼2mW), at the expense of less accuracy (1000ppm) [2]. RC-based references offer the lowest power consumption, but their accuracy is typically limited to ∼0.1% [3]. In RC relaxation oscillators, comparator offset and delay are the major sources of inaccuracy [4,5]. References based on frequency-locked loops (FLLs) circumvent these by locking an oscillator's frequency to the time-constant of an RC filter, but their accuracy is then limited by the nonlinear temperature dependency of on-chip resistors [3,6].Session 3.3 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.Electronic Instrumentation(OLD)Applied Quantum ArchitecturesMicroelectronic

    Coupled topographic and vegetation patterns in coastal dunes: Remote sensing observations and ecomorphodynamic implications

    No full text
    Vegetation plays a key role in stabilizing coastal dunes and barrier islands by mediating sand transport, deposition, and erosion. Dune topography, in turn, affects vegetation growth, by determining local environmental conditions. However, our understanding of vegetation and dune topography as coupled and spatially extensive dynamical systems is limited. Here we develop and use remote sensing analyses to quantitatively characterize coastal dune ecotopographic patterns by simultaneously identifying the spatial distribution of topographic elevation and vegetation biomass. Lidar-derived leaf area index and hyperspectral-derived normalized difference vegetation index patterns yield vegetation distributions at the whole-system scale which are in agreement with each other and with field observations. Lidar-derived concurrent quantifications of biomass and topography show that plants more favorably develop on the landward side of the foredune crest and that the foredune crestline marks the position of an ecotone, which is interpreted as the result of a sheltering effect sharply changing local environmental conditions. We conclude that the position of the foredune crestline is a chief ecomorphodynamic feature resulting from the two-way interaction between vegetation and topography

    Photograph of a twenty-five-year-old eucalyptus tree in a eucalyptus grove at the L.J. Rose Ranch, ca.1900. The barks on the trunk is pealing off to reveal the smooth surface underneath. The ground is littered with fallen leaves. Shrubs and grass cover the area in the background where other trees stand.; "Under the ownership of Leonard John Rose, the Sunny Slope Ranch live location was a showplace of orchards and vineyards, drawing as many as two to three hundred visitors a day. Rose learned how to grow grapes without irrigation, and the ranch became known for its brandy and fine wines." -- unknown author.; "The Old Grapevine holds a small segment of the original vine whose trellised branches once covered 10,000 square feet. It was a popular local gathering place where refreshments were served under the vine. Started as a cutting from the "Mother Vine" at the Mission, many local vineyards began from cuttings of this vine. L.J. Rose of Sunnyslope Ranch, just north and east of San Gabriel, started with such cuttings and grafted on many varieties of grapes new to this area. He later helped begin many a vineyard in Northern California. The San Gabriel Winery was among the worlds largest in the late 1800's, until a blight wiped out the vineyards and oranges became the main agricultural crop of the area. Today the park is once again a popular place for weddings, parties and social gatherings." -- unknown author
