Eseje o environmentální a zdravotní ekonomice
Get PDFEseje o Environmentální a Zdravotní Ekonomice Olexiy Kyrychenko Abstrakt V první kapitole zkoumáme dopad teploty na výrobní produkci v Indii a související mechanismy. Využitím výrobních dat na úrovni závodu a satelitních odhadů teplot z let 1998- 2007 jsme zjistili, že vztah mezi teplotou a výrobou vykazuje tvar obráceného U, přičemž zvláště velké ztráty nastávají při extrémně nízkých a vysokých teplotách. Taková nelinearita poskytuje cenný pohled na potenciální důsledky změny klimatu na blahobyt. Výpočty naznačují, že posun o 1 řC v roční distribuci denní teploty by vedl k čistým ztrátám ve výrobě ve výši 1,3 % nebo 0,6 miliardy USD, což odpovídá 0,5% snížení HDP Indie v roce 2007 pouze prostřednictvím výrobním sektoru. Odhadovaný vztah mezi teplotou a výrobou je řízen společnými účinky teploty na celkovou produktivitu faktorů a kapitál. Toto zjištění má důležité důsledky pro adaptaci. Výrobní sektor se může přizpůsobit měnícímu klimatu snížením citlivosti produktivity práce na teplotu a investicemi do strojního zařízení. Úpravy související s pracovních sil mohou také přispět k přizpůsobení tím, že vyrovnají přímé ztráty produktivity nebo usnadní přerozdělení pracovních sil. Na základě těchto strategií může Indická výroba dosáhnout cílů politiky v oblasti změny klimatu, aniž by ohrozila její růst a...Essays on Environmental and Health Economics Olexiy Kyrychenko Abstract In the first chapter, we examine the impact of temperature on manufacturing production in India and the underlying mechanisms. Using plant-level manufacturing data and satellite- based temperature estimates from 1998-2007, we find that the relationship between temperature and output exhibits an inverted U-shape, with especially large losses occurring at extreme cold and hot temperatures. Such nonlinearity provides valuable insight into the potential welfare consequences of climate change. Back-of-the-envelope calculations suggest that a 1řC shift in the annual distribution of daily temperature would lead to net losses in manufacturing output of 1.3% or USD 0.6 billion, equivalent to a 0.5% reduction in India's GDP 2007 through the manufacturing sector alone. The estimated temperature-output relationship is driven by the joint effects of temperature on total factor productivity and capital. This finding has important implications for adaptation. The manufacturing sector can adapt to changing climate by reducing the sensitivity of labor productivity to temperature and by making investments in machinery. Labor-related adjustments can also contribute to adaptation by offsetting direct productivity losses or facilitating labor reallocation....CERGEFakulta sociálních vědFaculty of Social Science
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Computational refinement of spectroscopic FRET measurements
No full textThis article supplies raw data related to a research article entitled “Joint refinement of FRET measurements using spectroscopic and computational tools” (Kyrychenko et al., 2017) [1], in which we demonstrate the use of molecular dynamics simulations to estimate FRET orientational factors in a benchmark donor-linker-acceptor system of enhanced cyan (ECFP) and enhanced yellow (EYFP) fluorescent proteins. This can improve the recalculation of donor-acceptor distance information from single-molecule FRET measurements
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Mean flow generation by Görtler Vortices in a rotating annulus with librating side walls
No full textLongitudinal libration of the cylinder side walls of a rotating annulus in the supercritical regime induces a centrifugally unstable Stokes boundary layer which generates Görtler vortices only in a portion of a libration cycle. We show for the first time that these vortices propagate into the fluid bulk and generate an azimuthal mean flow which is retrograde (prograde) over the outer (inner) cylinder side wall. Direct numerical simulations (DNS) are carried out and Reynolds-averaged equations and kinetic energy budget of mean and fluctuating flow are used as diagnostic equations to discuss the generation mechanism and scaling behavior of the azimuthal mean flow in the fluid bulk
Multivariate Polarimetric Bistatic Clutter Statistical Analysis
No full textThis paper deals with the analysis of simultaneously collected co- and cross-polarized bistatic sea-clutter returns with special emphasis on their representation as a Spherically Invari-ant Random Process (SIRP). The study is conducted by using appropriate testing procedures involving the complex envelope of the measured data that provide both first- and higher-order compatibility conditions. The results highlight that the SIRP model is a good candidate for the representation of bistatic coherent clutter, and usually the coherence time of the SIRP texture is longer than that in the monostatic case.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.Microwave Sensing, Signals & System
A Guiding Vector-Field algorithm for path-following control of nonholonomic mobile robots
Get PDFIn this paper, we propose an algorithm for path-following control of the nonholonomic mobile robot based on the idea of the guiding vector field (GVF). The desired path may be an arbitrary smooth curve in its implicit form, that is, a level set of a predefined smooth function. Using this function and the robot's kinematic model, we design a GVF, whose integral curves converge to the trajectory. A nonlinear motion controller is then proposed, which steers the robot along such an integral curve, bringing it to the desired path. We establish global convergence conditions for our algorithm and demonstrate its applicability and performance by experiments with wheeled robots.Accepted Author ManuscriptTeam Tamas Keviczk
