Food and travel author and college professor Matt Frank talks about American food culture
No full textFood and travel author and college professor Matt Frank suggests that he has little willpower when it comes to sampling new and exotic foods and says that he considers cuisine to be a little piece of a culture that he can consume and take with him. Frank reads from his book "The mad feast : an ecstatic tour through America's food" and takes questions from the audience. He also participates in the Michigan State University Undergraduate Creative Writing Awards ceremony which is held after his presentation. Frank is introduced by MSU Professor Marcia Aldrich. The event is convened by professor Robin Silbergleid, director of the MSU Creative Writing Program
Cryogenic operation and room temperature application of an optically-pumped surface-emitting semiconductor laser
No full textThis thesis reports how the performance of a Vertical-External-Cavity Surface-Emitting Laser (VECSEL) can be significantly improved by cooling the active region to cryogenic temperatures. Also presented is the development of a room temperature, stable, high power, wavelength-tuneable, mode locked VECSEL and its subsequent implementation as a pump laser in a system designed to generate single photons.The VECSEL is a type of semiconductor laser capable of producing high output power in near diffraction-limited beams. The semiconductor gain region is highly temperature sensitive and the output power of a VECSEL is limited by non-radiative Auger recombination. Previous research has shown that by cooling the gain chip the gain per carrier is increased, the carrier density at the point of threshold lasing is reduced and the onset of Auger-recombination induced thermal rollover is delayed.This thesis presents a VECSEL that uses a gain chip cooled to 83 K. The device exhibited a 53% x 10% reduction in the incident pump power required to reach laser threshold, a 4-fold increase in incident pump power tolerated prior to the onset of thermal rollover, and an increase in output power of more than an order of magnitude when its performance was compared to operation at 293 K. A mode locked VECSEL using a gain chip held at 143 K is also reported. Prior to this research the coldest temperature at which a VECSEL gain chip had been operated was 248 K. This work shows that cryogenic temperatures can significantly improve VECSEL performance and begins a new direction in VECSEL research.The mode locked VECSEL has surpassed the performance of other types of mode locked semiconductor laser and is now approaching the performance of fibre and solidstate lasers. It has yet to be commercialised and so, to demonstrate that the mode locked VECSEL is now a mature, reliable technology, this thesis reports the development and implementation of a mode locked VECSEL as a pump laser in a single photon generation system. The system generates coincidental pairs of photons and, by detecting one photon in the pair, the presence of the companion will be heralded. The wavelength flexibility, excellent beam quality and high pulse repetition rate make the mode locked VECSEL ideal for both quantum state engineering and heralded single photon generation
On solving wave equations on fixed bounded intervals involving Robin boundary conditions with time-dependent coefficients
No full textIn this paper, it is shown how characteristic coordinates, or equivalently how the well-known formula of d'Alembert, can be used to solve initial-boundary value problems for wave equations on fixed, bounded intervals involving Robin type of boundary conditions with time-dependent coefficients. A Robin boundary condition is a condition that specifies a linear combination of the dependent variable and its first order space-derivative on a boundary of the interval. Analytical methods, such as the method of separation of variables (SOV) or the Laplace transform method, are not applicable to those types of problems. The obtained analytical results by applying the proposed method, are in complete agreement with those obtained by using the numerical, finite difference method. For problems with time-independent coefficients in the Robin boundary condition(s), the results of the proposed method also completely agree with those as for instance obtained by the method of separation of variables, or by the finite difference method.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.Mathematical Physic
Interview of Robin Silbergleid, Michigan State University professor of English and head of the creative writing program, on her broad publishing credits, balancing between an academic career and a writing career, and blurring lines between different genres
No full textAuthor Robin Silbergleid, Michigan State University professor of English and head of the creative writing program, talks about her broad publishing credits and how she balances an academic career with a writing career. She comments on her memoir "Texas girl," suggests that clear genres are going away as lines between them become more blurred, and explains the differences between memoir, autobiography, and the novel. Silbergleid is interviewed by MSU Librarian Michael Rodriguez for the Michigan State University Libraries' Michigan Writers Series. Held in the MSU Main Library

Robin G. Collingwood. Philosophy of History as Philosophy of the Historical Cognition
No full textThe Author discusses a book "The Robin G. Collingood s philosophy of History" by Witold M. Nowak. He considers it as well done monographic picture of Collingwood's thinking. Nowak regards the philosophy of history of famous English thinker as a hermeneutical philosophy rather than philosophy of history itself including such basic ideas essential for the understanding of his philosophy like theory ofquestioning and answering, the method of the re-enactment, the concept of the absolute conditions. The book written by Nowak provides also to the Polish readers many precious biographical data and an interesting analysis of the cultural context ofColingwoodian thinking. It pays special attention to the late period of his work and its meaning
Saturated gain spectrum of VECSELs determined by transient measurement of lasing onset
No full textWe describe time-resolved measurements of the evolution of the spectrum of radiation emitted by an optically-pumped continuous-wave InGaAs-GaAs quantum well laser, recorded as lasing builds up from noise to steady state. We extract a fitting parameter corresponding to the gain dispersion of the parabolic spectrum equal to 79 30 fs2 and 36 6 fs2 for a resonant and anti-resonant structure, respectively. Furthermore the recorded evolution of the spectrum allows for the calculation of an effective FWHM gain bandwidth for each structure, of 11 nm and 18 nm, respectively.This paper was published in Optics Express and is made available as an electronic reprint with the permission of OSA.

The Cognitive Psychology of Planning
No full textThe Cognitive Psychology of Planning assesses recent advances in the scientific study of the cognitive processes involved in formulating, evaluating and selecting a sequence of thoughts and actions to achieve a goal. Approaches discussed range from those which look at planning in terms of problem-solving behaviour to those which look at how we control thoughts and actions within the frameworks of attention, working memory or executive function. Topics covered include: simple to complex tasks, well- and ill-defined problems and the effects of age and focal brain damage on planning. This survey of recent work in the cognitive psychology and cognitive neuropsychology of planning will be an invaluable resource for anyone studying or researching in the fields of thinking and reasoning, memory and attention. © 2005 Psychology Press.
