The Black Block : Opaque Page as a Graphic Device

2019

The black block, a rectangle of black printing ink on the page of a book, surrounded by blank margins, is a peculiar graphic device. Its literary tradition has usually been considered to start from Tristram Shandy, which includes a renowned black page in memory of “poor Yorick”. Nevertheless, Sterne’s gimmick can be seen as an allusion to an older typographical tradition of the so-called mourning pages, which were featured in books remembering the departed decades before Tristram Shandy. In this article, we analyze the ways in which the black block is used in narrative literature, with examples chosen mainly from 20th century experimental fiction. The block proves ambivalent in that it seem…

Uz žanra balstītas pieejas izmantošana pētnieciskā darba anotācijas un ievada rakstītmācīšanā

2018

Lai iegūtu bakalaura grādu, ir nepieciešamas labi attīstītas akadēmiskās rakstīšanas prasmes un zinātniski pētnieciskā darba žanra zināšanas, tādējādi ir svarīgi palīdzēt studentiem tās attīstīt. Šī pētījuma mērķis bija noskaidrot žanrā balstītas pieejas efektivitāti pētnieciskā darba rakstīšanai universitātē, izmantojot gadījuma izpēti. Tā ietvēra zinātniski pētnieciskā darba anotācijas un ievada rakstīšanas mācīšanu, nodarbību vērošanu, aptaujas un žanra analīzi. Pētījuma rezultāti parādīja studentu rakstīšanas iemaņu uzlabošanos attiecīgajos žanros. Var secināt, ka žanra pieeja ir efektīva, jo studenti apzinās anotācijas un ievada retorisko struktūru un valodas iezīmes un spēj izmantot i…

Connections Between Single-Level and Bilevel Multiobjective Optimization

2011

The relationship between bilevel optimization and multiobjective optimization has been studied by several authors and there have been repeated attempts to establish a link between the two. We unify the results from the literature and generalize them for bilevel multiobjective optimization. We formulate sufficient conditions for an arbitrary binary relation to guarantee equality between the efficient set produced by the relation and the set of optimal solutions to a bilevel problem. In addition, we present specially structured bilevel multiobjective optimization problems motivated by real-life applications and an accompanying binary relation permitting their reduction to single-level multiob…

Convergence Analysis of Distributed Set-Valued Information Systems

2016

This paper focuses on the convergence of information in distributed systems of agents communicating over a network. The information on which the convergence is sought is not rep- resented by real numbers, as often in the literature, rather by sets. The dynamics of the evolution of information across the net- work is accordingly described by set-valued iterative maps. While the study of convergence of set-valued iterative maps is highly complex in general, this paper focuses on Boolean maps, which are comprised of arbitrary combinations of unions, intersections, and complements of sets. For these important class of systems, we provide tools to study both global and local convergence. A distr…

Fuzzy temporal random sets with an application to cell biology

2007

Total Internal Reflection Fluorescence Microscopy (TIRFM) greatly facilitates to imaging the first steps of endocytosis, a process whereby cells traffic cargo from the cell surface to endosomes. Using TIRFM, fluorescent-tagged endocytic proteins are observed as overlapped areas forming random clumps of different sizes, shapes and durations. A common procedure to segment these objects consists of thresholding the original gray-level images to produce binary sequences in which a pixel is covered or not by a given fluorescent-tagged protein. This binary logic is not appropriate because it leaves a free tuning parameter to be set by the user which can influence on the conclusions of the statist…

Lau Effect And Binary Logic

1989

The Lau effect is applied to implement the whole set of binary logic operations optically. Our technique works with spatially incoherent light and does not require lenses or any other optical accessory.

Retinal vasculature segmentation and measurement framework for color fundus and SLO images

2020

Abstract The change in vascular geometry is an indicator of various health issues linked with vision and cardiovascular risk factors. Early detection and diagnosis of these changes can help patients to select an appropriate treatment option when the disease is in its primary phase. Automatic segmentation and quantification of these vessels would decrease the cost and eliminate inconsistency related to manual grading. However, automatic detection of the vessels is challenging in the presence of retinal pathologies and non-uniform illumination, two common occurrences in clinical settings. This paper presents a novel framework to address the issue of retinal blood vessel detection and width me…

Benchmarking non-photorealistic rendering of portraits

2017

We present a set of images for helping NPR practitioners evaluate their image-based portrait stylisation algorithms. Using a standard set both facilitates comparisons with other methods and helps ensure that presented results are representative. We give two levels of difficulty, each consisting of 20 images selected systematically so as to provide good coverage of several possible portrait characteristics. We applied three existing portrait-specific stylisation algorithms, two general-purpose stylisation algorithms, and one general learning based stylisation algorithm to the first level of the benchmark, corresponding to the type of constrained images that have often been used in portrait-s…
