The authors consider a binary synchronous stream cipher where a correlation has been identified between the keystream sequence and the output from one of the linear feedback shift registers (LFSR). They present a theoretical analysis of their recent algorithm for fast correlation attacks, based on the use of convolutional codes (see Advances in Cryptology - EUROCRYPT'99, Lecture Notes in Computer

Background/objectives: Alzheimer’s disease (AD) is currently diagnosed clinically using defined symptomatic diagnostic criteria. Pathological levels of CSF-biomarkers, high T-tau, P-tau and low Ab42 have been associated with AD however definition of cut off values differ. New diagnostic criteria that include the pathological CSF biomarkers have been suggested. How many AD patients in a routine cli

Moving from the ontological question "what is an image?" to the more performative, or ontogenetic, question "what can an image do?" this paper will discuss how non-representational theory could offer new ways to approach the materialities of the image. Drawing upon Gilles Deleuze's writings on the cinematic image, Charles Sanders Peirce's semiotics and Henri Bergson's writings on duration and memo

Popular Abstract in Swedish Synergonomiska bedömningar och interventioner genomfördes på icke-dator relaterade arbetsuppgifter vid återvinningsanläggningar, postsorteringsanläggningar och i operationssalar. Resultaten kan i viss mån tillämpas på andra yrken och arbetsplatser. Syftet med forskningen var att undersöka vilken påverkan synergonomiska interventioner hade vad gällande ögonbesvär, muskulVisual ergonomics evaluations and interventions were performed on non-computer work tasks at recycling facilities, post sorting facilities and operating theatres. The results can to some extent be applicable to other professions and workplaces. The purpose of the research was to investigate the effects of visual ergonomics interventions on eyestrain, musculoskeletal discomfort, headache, and visua

Scattering by planar geometries with plane metal inclusions are analyzed. The metal inclusions can be of arbitrary shape, and the material of the supporting slabs can be any linear (bianisotropic) material. We employ the method of propagators to find the solution of the scattering problem. The method has certain similarities with a vector generalization of the transmission line theory. A general re

This paper argues that dropped objects typically require that no other more prominent syntactic actor intervenes between the dropped object and the left edgfe of the clause

In this paper we give an introduction to the mathematical foundations of the optical waveguide design. A survey of the main results of the spectral theory of the Schr¨odinger operator on the line having compactly supported potential, with particular emphasis on the case of piece-wise constant potential is presented. This theory is then applied to the optical waveguide design problem of a piece-wis
