This chapter examines how the branching narrative framework of “Wandering Rocks” reflects the structure of the manneristic maze and emulates the nonlinear visual structures which are traced by the characters of Ulysses as they wander through Dublin’s streets. In light of Henri Poincaré’s definition of geometry as “the summary of the laws by which images succeed each other,” it explores how James Joyce presents time presented as the fourth dimension of space in his construction of a textual “picture of Dublin” which follows the movement of wandering bodies. This chapter provides a schema of the narrative network in “Wandering Rocks,” illustrating how Joyce’s textual remapping of Dublin involves the structural emulation of fundamental geometric constructs and related topographical concepts which involve the coincident meeting of lines (as in triangulation, parallax, and the Cartesian coordinate system). In light of the parallactic perspectives which are facilitated by the episode’s branching structure, this chapter demonstrates how the labyrinthine “Wandering Rocks” narrative epitomizes Joyce’s Brunonian perversion of unidirectional rectilinearity on a structural level, disrupting “wider manifestations […] of ‘conceptual and behavioral rectilinearity’” in its nonlinear form.

This paper is aimed to develop a model of the sign as homomorphism (i.e. similarity of form) as the initial part of a strict and fundamental theory of sign. Many various signs—photographs, pictures, sculptures, diagrams, surface maps, etc.—might be viewed in terms of homomorphism. The proposed model of sign as a homomorphism is derived using Aristotle’s theory of being. Two principles of Aristotle’s theory—form and matter—are used as elementary ideas in the model of sign. The main peculiarity of the undertaken approach to semiotics is treating a sign and a signified object as derivative ideas; they are constructed as compounds of form and matter. To achieve more strictness, the model of sign is treated in terms of the system of Cartesian coordinates modified for the articulation of being. Intentionality is viewed as the key idea in the model of sign. The approach to the definition of sign presented in this paper can be viewed as an ontological alternative to Peirce’s one.Keywords: sign as homomorphism, Aristotle, hylomorphism, Cartesian coordinate system, ontology.Aristotelio esaties teorijos semiotinės įžvalgosAlgirdas BudrevičiusSantraukaPagrindinis šio straipsnio tyrimo dalykas yra ženklas kaip žymimojo objekto homomorfizmas – tai yra ženklas kaip formos panašumas. Pagrindinis tikslas – sukurti ženklo kaip homomorfizmo modelį, kuris būtų griežtos, pamatinės ženklo teorijos pradinė dalis. Daug įvairių ženklų gali būti nagrinėjami kaip homomorfizmai: fotografijos, paveikslai, skulptūros, diagramos, žemėlapiai ir kt. Pasiūlytas homomorfinio ženklo modelis išvestas naudojant Aristotelio esaties teoriją. Kaip elementariosios sąvokos jame naudojami du Aristotelio esaties teorijos principai – forma ir materija (medžiaga). Dėstomo požiūrio ypatumas semiotikos atžvilgiu yra tas, kad ženklas ir žymimasis objektas traktuojami kaip išvestinės sąvokos; jos konstruojamos kaip formos ir materijos junginiai. Siekiant, kad modelis būtų griežtesnis, jam sudaryti naudojama Dekarto koordinačių sistema, pritaikyta esaties artikuliavimui. Homomorfinio ženklo apibrėžimo kertine laikoma intencionalumo sąvoka. Straipsnyje pateiktas požiūris į ženklo apibrėžimą gali būti laikomas ontologine alternatyva Peirce’o požiūriui.

This part introduces and illustrates the idea of a legal dilemma by means of a hypothetical Cartesian coordinate system. The introduction alsosets out the objectives of the book. It does so with reference to three research questions concerning, first, the definition of a legal dilemma, second, the possibility of the existence of a legal dilemma, and, finally, the way in which the international legal order should address legal dilemmas. Subsequently, the introduction outlines five examples to which the book keeps referring. The examples concern the regulation of nuclear weapons, submarine warfare, military alliances, conflicting infrastructure treaties, and the rescue of persons in distress at sea.

This paper discusses the large-displacement flexural-torsional behavior of a straight elastic beam with uniform circular cross-section subject to arbitrary terminal bending and twisting moments. The beam is assumed to be free from any kinematic constraints at both ends. The equilibrium equation is solved analytically with the full expression for curvature to obtain the deformed configuration in a three-dimensional Cartesian coordinate system. The results show the influence of the terminal moments on the beam’s deflected configuration.

Lattice Boltzmann models for diffusion equation are generally in Cartesian coordinate system. Very few researchers have attempted to solve diffusion equation in spherical coordinate system. In the lattice Boltzmann based diffusion model in spherical coordinate system extra term, which is due to variation of surface area along radial direction, is modeled as source term. In this study diffusion equation in spherical coordinate system is first converted to diffusion equation which is similar to that in Cartesian coordinate system by using proper variable. The diffusion equation is then solved using standard lattice Boltzmann method. The results obtained for the new variable are again converted to the actual variable. The numerical scheme is verified by comparing the results of the simulation study with analytical solution. A good agreement between the two results is established.

Discuss the limits imposed by the paraxial approximation. Define the sign convention based on the cartesian coordinate system, the foiundation of analytic geometery. Demonstrate ray tracing technique to derive the ABCD maxtrix which will generate both the gaussian and Newtonian form of the thin lens equation and the lens maker’s equation. The cardinal points of a lens are also derived. The ABCD matrix is used to explore the methods used in ray tracing to locate the aperture stop of a Cooke’s triplet lens system. In the problem set, the student is asked to use the aperture stop to locate the entrance and exit pupil of a Cooke’s triplet.

<p class="1Body">Selection of the coordinate system is essential for rotation problems. Otherwise, mistakes may occur due to inaccurate measurement of angular speed. Approximate inertial coordinate system selections for rotation problems should be the gravitational field of the celestial body higher than the object being rotated: (1) the Earth fixed Cartesian coordinate system for normal rotation problem; (2) heliocentric - geocentric Cartesian coordinate system for satellites orbiting the Earth; (3) the Galaxy Heart - heliocentric Cartesian coordinates for Earth's rotation around the Sun. In astrophysics, mass calculation error and angular velocity measurement error lead to a black hole conjecture.</p>
