Adding Bloom to High-Dynamic-Range Tone Mapping
No full textWe present a technique for enhancing high-dynamic-range tone mapping algorithms by adding the bloom effect to bright areas. Bloom is based on the fact that real-life lenses convolve light and make bright areas emit a glow. The algorithm takes a set of images with different exposures as input, and performs a tone mapping algorithm on these. It then takes the image with the lowest exposure value to create the bloom effect. It then perform a convolution on this image with with a kernel that represents the response to one point of light. The resulting image is then added on top of the tone mapped image. We also present parameters to change the spread of the glowing effect, how bright an area needs to be to get a significant glow, and the intensity of the glow when applied. Furthermore, the kernel can be changed to create different types of glow and highlights. These things make the technique versatile and allows the photographer to customize the effect.https://github.com/ricardovogel/tonemap-and-bloom Code repositoryCSE3000 Research ProjectComputer Science and Engineerin

The Gnostic Author of Harold Bloom
No full textČlanak isprva kontekstualizira pojavu tzv. authorship studies koje su nastale kao svojevrsna reakcija na poststrukturalističko (R. Barthes i M. Foucault) redefiniranje autorstva. U taj se kontekst zatim pozicionira Harold Bloom. On je, naime, iz uvjerenja da su poststrukturalističke antihumanističke tendencije pokrenule degenerativne procese, pa u konačnici i rastakanje književnosti u prvi plan svoje književne teorije postavio kanon i autora. Dok se o prvome znatno pisalo, drugo – pitanje autorstva – u studijama o Bloomu uglavnom je zanemareno. Stoga se u članku pozornost pridaje ponajprije Bloomovu tumačenju autora. Nastoji se pokazati da njegovo shvaćanje autorstva (kao, uostalom, i kanona) proizlazi iz gnostičke tradicije (Valentin i Lurija). Autor je za Blooma, zaključuje se, ponajprije genij – onaj koji stvara potaknut „iskrom“, pneumom, božanstvom u dnu vlastita uma, što je zapravo također stanoviti antihumanizam.The article contextualizes at first the occurrence of the so-called authorship studies that arose as a kind of reaction to the post-structuralist (R. Barthes and M. Foucault) redefinition
of authorship. Harold Bloom then positioned himself in this context. Namely, from the belief that post-structuralist anti-humanist tendencies initiated degenerative processes, and ultimately the disintegration of literature, he placed the canon and the author at the forefront of his literary theory. While much has been written about the first term, the second—the question of the authorship—has been mostly neglected in Bloom studies. Therefore, the article focuses primarily on Bloom’s interpretation of the author. The article tries to show that his understanding of authorship (as well as the canon, after all) derives from the Gnostic tradition (Valentin and Luria). For Bloom, the author is, it is concluded, primarily a genius—one who creates inspired by a “spark,” a pneuma, a divinity at the bottom of one’s own mind, which is actually also a certain form of anti-humanism
Bloom weighted bounds for sparse forms associated to commutators
No full textIn this paper we consider bilinear sparse forms intimately related to iterated commutators ofa rather general class of operators. We establish Bloom weighted estimates for these formsin the full range of exponents, both in the diagonal and off-diagonal cases. As an application,we obtain new Bloom bounds for commutators of (maximal) rough homogeneous singularintegrals and the Bochner–Riesz operator at the critical index. We also raise the questionabout the sharpness of our estimates. In particular we obtain the surprising fact that even inthe case of Calderón–Zygmund operators, the previously known quantitative Bloom boundsare not sharp for the second and higher order commutators.Fil: Lerner Andrei K..

Bloom
No full textBloom details a personal journey of loss and the growth that came after it. It explores ideas such as the Abject, and those related to Embodied Geographies, Auto-ethnography, Trauma Theory, Ecology, the Rhizome, as well as in a text by Pravu Mazumdar titled Preferring Not to Die. Through these ideas the reader hopefully comes to view the wider relevance of connecting biographical experiences with ideas in order to understand a state of being that has transformed through loss and growth. Detailing the processes and different materials used throughout the physical jewellery work of Bloom allows the reader to understand the evolution of Antonia Boyle’s master’s project and its different iterations over a period of time.
A community of practice features Lucie Marjerus, Otto Kunzli, Naomi Filmer, Pierre Degen, Majorie Schick, Christoph Zellweger, Biojewellery, Hanna Hedman, Dalya Lutwak, Diana Scherer, Lauren Simeoni and Melinda Young, and Vicki Mason. Their work provides a context within which related ideas are explored via a multitude of materials.
The dissertation rounds off by detailing the importance of documentation of previous iterations of Bloom and the choice of gallery and proposed exhibition plans.
Bloom is a story of the evolution of life and how to embrace loss as a positive transitional stage. Bloom is a story of life and its cycle, a story which could be relevant to all as we all face loss of some kind or another. Bloom is a state of being which is embraced wholeheartedly by the author and this dissertation details the physical and mental processes of grief and post-traumatic growth that led to it
The decline process and major pathways of Microcystis bloom in Taihu Lake, China
No full textEutrophication has become a serious concern in many lakes, resulting in cyanobacterial blooms. However, the mechanism and pathways of cyanobacteria decline are less understood. To identify and define the growth and decline of Microcystis blooms in Taihu Lake of China, and to illuminate the destination of surface floating blooms, we investigated the biomass distribution and variations in colony size, morphology, and floating velocity from October 2008 to September 2009. The results showed that the Microcystis bloom declined in response to biomass decrease, colony disaggregation, buoyancy reduction, and increased phytoplankton biodiversity, and these indicative parameters could be applied for recognition of the development phases of the bloom. Three major decline pathways were proposed to describe the bloom decline process, colony disaggregation (Pathway I), colony settlement (Pathway II), and cell lysis in colonies (Pathway III). We proposed a strategy to define the occurrence and decline of Microcystis blooms, to evaluate the survival state under different stress conditions, and to indicate the efficiency of controlling countermeasures against algal blooms.Eutrophication has become a serious concern in many lakes, resulting in cyanobacterial blooms.

\u3cem\u3eThe Old Man and the Sea\u3c/em\u3e
No full textReader’s companion geared to young adults. Reprints excerpts of essays from such well-known Hemingway scholars as Carlos Baker, Linda W. Wagner, Philip Young, and Bickford Sylvester. Includes a brief biography and chronology of the author’s life along with an introductory essay by Bloom in which he characterizes the novel as both “repetitive and self-indulgent.” With so little respect shown for either the author or novella, one wonders why Bloom bothered to edit the volume
UVB Radiation as a Potential Selective Factor Favoring Microcystin Producing Bloom Forming Cyanobacteria
No full textDue to the stratospheric ozone depletion, several organisms will become exposed to increased biologically active UVB (280-320nm) radiation, not only at polar but also at temperate and tropical latitudes. Bloom forming cyanobacteria are exposed to UVB radiation on a mass scale, particularly during the surface bloom and scum formation that can persist for long periods of time. All buoyant species of cyanobacteria are at least periodically exposed to higher irradiation during their vertical migration to the surface that usually occurs several times a day. The aim of this study is to assess the influence on cyanobacteria of UVB radiation at realistic environmental intensities. The effects of two UVB intensities of 0.5 and 0.99 W/m(2) in up to 0.5 cm water depth were studied in vitro on Microcystis aeruginosa strains, two microcystin producing and one non-producing. After UVB exposure their ability to proliferate was estimated by cell counting, while cell fitness and integrity were evaluated using light microscopy, autofluorescence and immunofluorescence. Gene damage was assessed by TUNEL assay and SYBR Green staining of the nucleoide area. We conclude that UVB exposure causes damage to the genetic material, cytoskeletal elements, higher sedimentation rates and consequent cell death. In contrast to microcystin producers (PCC7806 and FACHB905), the microcystin non-producing strain PCC7005 is more susceptible to the deleterious effects of radiation, with weak recovery ability. The ecological relevance of the results is discussed using data from eleven years' continuous UVB radiation measurements within the area of Ljubljana city (Slovenia, Central Europe). Our results suggest that increased solar radiation in temperate latitudes can have its strongest effect during cyanobacterial bloom formation in spring and early summer. UVB radiation in this period may significantly influence strain composition of cyanobacterial blooms in favor of microcystin producers.Due to the stratospheric ozone depletion, several organisms will become exposed to increased biologically active UVB (280-320nm) radiation, not only at polar but also at temperate and tropical latitudes.
