Abstract:
An algorithm of two stages collision detection is presented for moving objectives in virtual scene. Firstly, AABB bounding box was used to test the intersection of interesting objects in coarse detection stage. Then combining space projection with Z-buffer algorithm, the potential intersecting objects in previous step were tested in precision detection stage, thus we can obtain objects collision data information and complete object collision detection. Finally experimental results show that the algorithm is more efficiency than traditional bounding box detection, the improved technology can realize further accurate collision detection.

Abstract:
Abstract In the face of problems such as welding of small objects or too small welding space, an application method of welding small plane intersecting objects based on point laser was proposed. The demonstration points pointing to different planes were preset, and the laser displacement sensor was driven to measure the physical value by simulating the sharp workpiece of the welding gun. Multiple projections at different locations were made on a certain plane of the welding object, so as to ensure that the laser points were not collinear and obtain the laser point parameter set. The plane equation was solved respectively according to the planes pointed by different demonstration points, and a geometric model was built. The equation of the intersecting line between the planes in the welding object was calculated. The points on the line were obtained as the welding start points. The workpiece tip was controlled to move along the intersection direction by the mechanical arm, so as to achieve the weld effect.

Abstract:
To autonomously move and operate objects in cluttered indoor environments, a service robot requires the ability of 3D scene perception. Though 3D object detection can provide an object-level environmental description to fill this gap, a robot always encounters incomplete object observation, recurring detections of the same object, error in detection, or intersection between objects when conducting detection continuously in a cluttered room. To solve these problems, we propose a two-stage 3D object detection algorithm which is to fuse multiple views of 3D object point clouds in the first stage and to eliminate unreasonable and intersection detections in the second stage. For each view, the robot performs a 2D object semantic segmentation and obtains 3D object point clouds. Then, an unsupervised segmentation method called Locally Convex Connected Patches (LCCP) is utilized to segment the object accurately from the background. Subsequently, the Manhattan Frame estimation is implemented to calculate the main orientation of the object and subsequently, the 3D object bounding box can be obtained. To deal with the detected objects in multiple views, we construct an object database and propose an object fusion criterion to maintain it automatically. Thus, the same object observed in multi-view is fused together and a more accurate bounding box can be calculated. Finally, we propose an object filtering approach based on prior knowledge to remove incorrect and intersecting objects in the object dataset. Experiments are carried out on both SceneNN dataset and a real indoor environment to verify the stability and accuracy of 3D semantic segmentation and bounding box detection of the object with multi-view fusion.

Abstract:
When using the traditional Douglas–Peucker (D–P) algorithm to simplify linear objects, it is easy to generate results containing self-intersecting errors, thus affecting the application of the D–P algorithm. To solve the problem of self-intersection, a new vector line simplification algorithm based on the D–P algorithm, monotonic chains and dichotomy, is proposed in this paper. First, the traditional D–P algorithm is used to simplify the original lines, and then the simplified lines are divided into several monotonic chains. Second, the dichotomy is used to search the intersection positions of monotonic chains effectively, and intersecting monotonic chains are processed, thus solving the self-intersection problems. Two groups of experimental data are selected based on large data sets. Results demonstrate that the proposed experimental method has advantages in algorithmic efficiency and accuracy when compared to the D–P algorithm and the Star-shaped algorithm.

In order to improve the speed of collision detection between objects in the large-scale and complex scene, this paper proposed an improved collision detection algorithm based on GPU, In this method, we first divided the virtual space into several grids to rule out the impossible intersecting objects rapidly using the GPU acceleration technology; secondly, we adopted parallel technology to build K - DOP bounding boxes for the objects in the same grids and then detected whether the K - DOP bounding boxes intervene or collide to conform the potential colliding primitive pairs; Finally we traveled the final triangle intersection tests on GPU. Compared to the traditional K-DOP compared bounding box collision detection, The algorithm can effectively improve the real-time collision detection.

Abstract:
In Drosophila, the functionally conserved transcription factor, doublesex (dsx), is pivotal to the specification of sexual identity in both males and females. One of its key dedicated roles involves regulating the development of a sexually dimorphic nervous system (NS) that underlies both male and female reproductive behaviours. Specific inhibition of the function of dsx-expressing neurons in males and females results in a global disruption of these sex-specific behavioural outputs. However, little is known about the functional organisation of this dsx circuit that encodes the potential to display these behaviours. Such investigations require the generation of a novel transgenic tool, capable of separating the function of dsx in the NS from that of the body. To achieve this, I generated a novel split-GAL4 dsxGAL4-DBD hemidriver by ends in homologous recombination. Coupling the novel tool with the pan-neuronal elavVP16-AD hemidriver, revealed spatial restriction of dsxGAL4-DBD/elavVP16-AD expression to dsx neurons only; enabling the realisation of novel patterns of dsx-expression in the peripheral NS. Next, the ability to elicit male-specific behavioural outputs upon activation of all dsx neurons formed the basis of a large behavioural screen aimed at parsing dsx circuitry into functionally distinct clusters. I utilised the novel dsxGAL4-DBD hemidriver to screen a large collection of extant enhancer trap lines (ETVP16-AD), for the elicitation of distinct sub-behaviours of male courtship. Here, I show that the activity of dsx-expressing clusters in: i) the brain (dsx-pC1, -pC2 and -pC3 collectively) regulate the early steps of male courtship (initiation, orientation and wing extension), ii) the pro- and mesothoracic ganglia (dsx-TN1 and -TN2) regulate the middle steps of male courtship (wing extension and possibly courtship song) and iii) the abdominal ganglia (dsx-Abg) regulate the late steps of male courtship (abdominal curling, attempted copulation and copulation). These data establish functional correlations between dsx clusters in distinct neuroanatomical foci and specific sub-behaviours of the courtship repertoire. Furthermore, the novel intersectional tool primed a collaborative study on female post-copulatory behaviours. We identified key sensory neurons in the female reproductive tract involved in initiating post-mating behaviours. Subsequent functional interrogations of dsx circuitry in the central NS revealed a subset of dsx-expressing neurons in the Abg that mediate changes in the female behavioural repertoire after mating. Characterisation of this relatively simple neural circuitry sheds light on the organisation of the fly brain. Ultimately, future studies will define principles of neural circuit operation, which may be similarly conserved in the nervous systems of higher animals.

Abstract:
In this thesis we employ string perturbation theory in toroidal orbifold models to study aspects of supersymmetry breaking in type IIB string theory. First, we determine the dependence of physical Yukawa couplings on blow-up moduli in models with D3-branes at orbifold singularities. Blow-up moduli are scalar fields describing the size of small blow-up cycles in the compactification geometry. In models implementing moduli stabilisation these fields can acquire F-terms and break supersymmetry. We examine the moduli-dependence of physical Yukawa couplings at string tree-level by computing disk correlation functions involving a Yukawa interaction of visible sector fields and an arbitrary number of blow-up moduli. We perform the calculation for one blow-up insertion explicitly and find that the correlation function vanishes if the blow-up modulus is associated with a small cycle distant to the visible sector. For more than one blow-up insertion we show that all such correlation functions are exponentially suppressed by the compactification volume. We explain how these results are relevant to suppressing soft terms to scales parametrically below the gravitino mass. Further, we determine corrections to holomorphic Yukawa couplings on D3-branes at an orbifold singularity due to non-perturbative effects such as gaugino condensation on a stack of D7-branes. This can be done by calculating a one-loop threshold correction to the gauge coupling on the D7-branes. We show that, if present, the new contributions to Yukawa couplings are not aligned with the tree-level couplings. As the new Yukawa couplings contribute to soft A-terms they are sources of flavour-changing neutral currents. Last we discuss an effect unrelated to supersymmetry breaking. We show that orbifold models with D3-branes at orbifold singularities can exhibit kinetic mixing of different massless Abelian factors. For this to be possible, the relevant U(1) factors have to be associated with more than one orbifold singularity.

Abstract:
The following commentary details aspects of my recent compositions attempting to bring about intersections between subjects and objects. I demonstrate how my compositions highlight an interplay between the poles of subjectivity vs objectivity, human vs nonhuman and nature vs culture. Various musical precedents rooted in objectivity form the basis of this endeavour, such as the inaudible cosmic vibrations proposed by the Pythagoreans' Musica universalis, the chance procedures of mid twentieth-century experimental music, and the Platonic forms of Tom Johnson. However, although these standpoints do attempt to broaden the scope of music beyond the human sphere, they remain most often framed by transcendent discourse without explicitly addressing the subjective implications of such work. I propose an approach to composition that distances itself from a transcendental perspective, instead choosing to highlight the effects that objectivity elicits in human beings, while maintaining the presence of an external reality that remains inscrutable. Thus, my portfolio addresses the precise ways in which subjectivity remains present even within an objective musical discourse, whether through exploring psychological responses to chance, the existential boredom brought on by unchanging forms, subjective reactions to the objecti�cation of the human body, and the input of the imagination in the face of withdrawn or speculative musical objects.

Abstract:
Higher-order recursion schemes are systems of equations that are used to define finite and infinite labelled trees. Since, as Ong has shown, the trees defined have a decidable monadic second order theory, recursion schemes have drawn the attention of research in program verification, where they sit naturally as a higher-order, functional analogue of Boolean programs. Driven by applications, fragments have been studied, algorithms developed and extensions proposed; the emerging theme is called higher-order model checking. Kobayashi has pioneered an approach to higher-order model checking using intersection types, from which many recent advances have followed. The key is a characterisation of model checking as a problem of intersection type assignment. This dissertation contributes to both the theory and practice of the intersection type approach. A new, fixed-parameter polynomial-time decision procedure is described for the alternating trivial automaton fragment of higher-order model checking. The algorithm uses a novel, type-directed form of abstraction refinement, in which behaviours of the scheme are distinguished according to the intersection types that they inhabit. Furthermore, by using types to reason about acceptance and rejection simultaneously, the algorithm is able to converge on a solution from two sides. An implementation, Preface, and an extensive body of evidence demonstrate empirically that the algorithm scales well to schemes of several thousand rules. A comparison with other tools on benchmarks derived from current practice and the related literature puts it well beyond the state-of-the-art. A generalisation of the intersection type approach is presented in which higher-order model checking is seen as an instance of exact abstract interpretation. Intersection type assignment is used to characterise a general class of safety checking problems, defined independently of any particular representation (such as automata) for a class of recursion schemes built over arbitrary constants. Decidability of any problem in the class is an immediate corollary. Moreover, the work looks beyond whole-program verification, the traditional territory of model checking, by giving a natural treatment of higher-type properties, which are sets of functions.

Abstract:
Realistic lighting models are an important component of modern computer generated, interactive 3D applications. One of the more difficult to emulate aspects of real-world lighting is the concept of indirect lighting, often referred to as global illumination in computer graphics. Balancing speed and accuracy requires carefully considered trade-offs to achieve plausible results and acceptable framerates. We present a novel technique of supporting global illumination within the constraints of the new DirectX Raytracing (DXR) API used with DirectX 12. By pre-computing spherical textures to approximate the diffuse color of dynamic objects, we build a smaller set of approximate geometry used for second bounce lighting calculations for diffuse light rays. This speeds up both the necessary intersection tests and the amount of geometry that needs to be updated within the GPU's acceleration structure. Our results show that our approach for diffuse bounced light is faster than using the conservative mesh for triangle-ray intersection in some cases. Since we are using this technique for diffuse bounced light the lower resolution of the spheres is close to the quality of traditional raytracing techniques for most materials.

Abstract:
Korsningar, busshållplatser, söderbackar och lastkajer är ytor med extrem påkänning på grund av hög trafikbelastning, låg hastighet, accelerationer, inbromsningar, svängningar, spårbundenhet och utsatthet för höga temperaturer. Den speciella lastsituationen riskerar orsaka spårbildning, vilket är det vanligaste problemet i korsningar. Genom att anpassa beläggningen efter den utsatta ytan så kan projektören påverka vägens funktion och livslängd. Syftet med detta examensarbete var att studera vilka beläggningsåtgärder som är lämpliga för utsatta körytor såsom korsningar och busshållplatser samt att se vad som orsakar skadebilden i en skadedrabbad korsning. Vidare var syftet att jämföra tre beläggningsalternativ för att se vilket som var mest fördelaktigt ur ett livslängds- och kostnadsperspektiv. Frågeställningarna var följande: 1. Vilka beläggningar är lämpliga för särskilt utsatta körytor såsom korsningar och busshållplatser? 2. Vad orsakar skadebilden vid frånfarten på Malmslättsvägen vid korsningen Malmslättsvägen/ Kaserngatan? 3. Vilken beläggningsåtgärd av ABS11, Densiphalt och PMA är bäst ur ett livslängd- och kostnadsperspektiv under 20 år för korsningen Malmslättsvägen/ Kaserngatan? För att besvara frågeställningarna gjordes litteraturstudier samt en fallstudie i form av okulär bedömning och balkanalys i det aktuella vägsnittet. Dessutom jämfördes livslängd och kostnader mellan beläggningsalternativen i PMS Objekt respektive genom en ekonomisk beräkningsmetod. Resultatet visade att ett bindlager kan uppta de skjuvkrafter som uppstår på utsatta ytor och förhindrar därmed sprickbildning och deformationer. CBÖ och platsgjuten betong har i studier visat begränsa spårbildning. Densiphalt är lämplig som beläggning på utsatta ytor och ger samtidigt ytan motståndskraft mot olja och bensin. IM är starkare, styvare och mindre deformationsbenägen än en vanlig asfalt och är därför lämplig på högtrafikerade vägar. Fallstudien på det aktuella vägsnittet visade att skadebilden hade två orsaker. Dels fanns ett ytslitage som var orsakat av den spårbundna dubbdäckstrafiken. Dessutom förekom plastisk deformation i det andra och tredje asfaltlagret till följd av otillräcklig stabilitet i asfaltmassan med hänsyn till den långsamtgående och stillastående trafiken. De obundna lagren var till synes opåverkade vid balkanalysen. Jämförelsen mellan beläggningsalternativen visade att Densiphalt hade längst livslängd följt av PMA och ABS11. Kostnadsmässigt hade PMA lägst annuitet följt av Densiphalt och ABS11. Orsaken till att ABS11 var dyrast var troligen behovet av mellanliggande akutåtgärder i form av gjutasfalt. Slutsatsen var att kompletterande bindlager, CBÖ, PMA, Densiphalt, betong och IM var lämpliga beläggningar för särskilt utsatta ytor. Skadebilden vid det undersökta vägsnittet bedömdes bero på ytslitage på grund av spårbunden dubbdäckstrafik samt plastisk deformation till följd av tung trafik. Densiphalt hade längst livslängd och PMA hade lägst annuitet. Konventionell ABS11 var sämst ur både livslängds- och kostnadsperspektiv, vilket bedömdes bero på behovet av mellanliggande akutåtgärder i form av gjutasfalt.

This article examines consumption from a cultural perspective, with particular emphasis on taste and performativity as well as the ways in which to navigate the forest of objects and their meanings. It first reviews the current state and future of consumption studies through the lens of intersecting research vectors in the fields of consumption, taste, and materiality. It then considers postmodern theories of consumption, focusing on three senses in which the concept of aestheticization has been employed. It also explains how material culture affords symbolic evidence of a person’s taste, and more broadly, is generative of their social identity. Finally, it addresses questions of individualism and hedonism, as well as the extent to which consumerism is culturally and socially divisive or constructive, and proposes a program for a cultural sociological approach to consumption.

Full text
Abstract:
This book compares things, objects, concepts, and ideas. It is also about the practical acts of doing comparison. Comparison is not something that exists in the world, but a particular kind of activity. Agents of various kinds compare by placing things next to one another, by using software programs and other tools, and by simply looking in certain ways. Comparing like this is an everyday practice. But in the social sciences, comparing often becomes more burdensome, more complex, and more questions are asked of it. How, then, do social scientists compare? What role do funders, their tools, and databases play in social scientific comparisons? Which sorts of objects do they choose to compare and how do they decide which comparisons are meaningful? Doing comparison in the social sciences, it emerges, is a practice weighed down by a history in which comparison was seen as problematic. As it plays out in the present, this history encounters a range of other agents also involved in doing comparison who may challenge the comparisons of social scientists themselves. This book introduces these questions through a varied range of reports, auto-ethnographies, and theoretical interventions that compare and analyse these different and often intersecting comparisons. Its goal is to begin a move away from the critique of comparison and towards a better comparative practice, guided not by abstract principles, but a deeper understanding of the challenges of practising comparison.

Abstract:
This volume investigates the various interactions of people, feelings, and things throughout pre-modern Europe. The subject of materiality has been gaining interest in recent historical inquiry, alongside growing emphasis on the relationships between objects, emotions, and affect in archaeological and sociological research. The historical intersections between materiality and emotions, however, have remained under-theorized, particularly with respect to objects which have continuing resonance over extended periods of time, or across cultural and geographical space. The book addresses this need to develop an appropriate cross-disciplinary theoretical framework for analysing the emotional meanings of objects in European history. It draws together an international group of historians, art historians, curators, and literary scholars working on a variety of cultural, literary, visual, and material sources. Objects considered include books, letters, prosthetics, religious relics, shoes, stone, and textiles, and individual chapters address the ways in which emotions such as despair, fear, grief, hope, love, and wonder become inscribed in and ascribed to these items, producing ‘emotional objects’ of significance and agency.

Abstract:
This book provides an introduction to algebraic cycles on complex algebraic varieties, to the major conjectures relating them to cohomology, and even more precisely to Hodge structures on cohomology. The book is intended for both students and researchers, and not only presents a survey of the geometric methods developed in the last thirty years to understand the famous Bloch-Beilinson conjectures, but also examines recent work by the author. It focuses on two central objects: the diagonal of a variety—and the partial Bloch-Srinivas type decompositions it may have depending on the size of Chow groups—as well as its small diagonal, which is the right object to consider in order to understand the ring structure on Chow groups and cohomology. An exploration of a sampling of recent works by the author looks at the relation, conjectured in general by Bloch and Beilinson, between the coniveau of general complete intersections and their Chow groups and a very particular property satisfied by the Chow ring of K3 surfaces and conjecturally by hyper-Kähler manifolds. In particular, the book delves into arguments originating in Nori's work that have been further developed by others.

Abstract:
This chapter explores the intersection between employer branding and talent management. In considering this intersection, it reflects upon the phenomenon of human resources (HR) practice differentiation in the context of both employer branding and talent management. In particular, it considers some similarities between brand management programs that are likely to differentiate HR practices based on perceived talent versus employer-brand segmentation that is more likely to differentiate HR practices on the basis of employee needs and wants. The chapter also reflects upon the potential implications for an organization’s employer brand and perceived employment offering when organizations take an object- versus subject-oriented approach to differentiating the workforce based on talent identification.

Abstract:
Chapter 4 changes the focus from the shape of the street network and the surfaces applied to it to considerations of street’s architectural components. To do so, it dissects the canonical shape of the Pompeian street—a cambered, impermeable stone surface abutting high curbs with pedestrian crossings and intersections and elsewhere—to better understand how this space was formed and how it functioned. The individual components of the street—paving stones, curbstones, stepping stones, and guard stones—are discussed in a series of brief but detailed mini-essays, each of which takes a morphological, functional, and evolutionary approach to the form, distribution, and life cycle of these objects.

Abstract:
AbstractTo generate suitable grasping positions between tessellated handling objects and specific planar grippers, we propose a 2D analytical approach which uses a polygon clipping algorithm to generate detailed information about the intersection between both objects. With the generated knowledge about the intersection we check whether its shape fits to the set criteria of the operator and represents a valid grasping position. Before the polygon clipping algorithm is applied, a preprocessing step is performed, where appropriate surfaces from the handling object and the gripper are extracted. After rotating all surfaces into a common plane, potential clipping positions are detected and the clipping is performed to get an accurate intersection detection. The validation shows comparable running times to a OBBTree algorithm (0.1 ms per grasping position) while increasing the stability of the results from 30 to 100% for the evaluated test objects.

Abstract:
Abstract A nonlinear programming formulation is developed for minimizing the area required to position a set of pre-defined objects without overlap. The objects consist of polygons with an arbitrary number of edges. Nonconvex polygons are assumed which allows for the modelling of complex parts, including parte with holes. A quadtree representation is formed for each polygon and intersections are determined by traversing quadtrees for the potentially intersecting objects. The design variables are selected to be the x and y location and the rotation for each polygon that is to be positioned. An exterior penalty function method is used to generate the solution to the resulting nonlinear programming problem. A nongradient search technique is used due to the discrete nature of the overlap constraints. Example problems are presented and extensions to other classes of problems are discussed.

Abstract:
In some industrial applications such as turbine airfoil film cooling, coolant passage configurations must maintain sufficient pressure margin to prevent hot gas ingestion whilst using holes of large enough diameter to avoid foreign object blockage. This frequently means that some regions of a film-cooled surface are provided with excess air, or that exhausting film jets are over-blown, adversely amplifying local mixing or coolant separation and therefore enhancing heat flux. A cooling system featuring intersecting passages would allow a high pressure margin to be obtained using discrete, localized loss mechanisms where flows intersect. The degree of loss could be tailored to the local internal and external flow conditions by altering the intersection extent (i.e. the degree of intersecting passage offset), thereby optimizing the use of coolant. Furthermore, localized in-passage convective heat transfer enhancements caused by thin boundary layers and impinging flows in the vicinity of the intersections would improve total heat flux (Watts per square meter) despite surface area lost to intersection voids. As the heat transfer and loss enhancements do not rely on intricately manufactured flow features, the cooling performance is likely to be robust in industrial applications, extending component life. An experimental and computational investigation of the flow through two intersecting cylindrical pipes has been carried out at turbine engine-representative conditions to test these hypotheses. While previous workers have characterized loss and heat transfer in co-planar intersecting holes, this first-of-a-kind study parametrically investigates both fully and partially-intersecting passages, accounting for passage offsets due to typical manufacturing tolerances or purpose-built localized loss enhancements. The loss coefficient across the intersection has been experimentally determined for a range of intersection angles and degrees of intersection in a large scale model running at near atmospheric conditions. The results are used to develop an empirical correlation for the loss coefficient for the isolated intersecting circular channel. A commercial computational fluid dynamics (CFD) code, FLUENT©, has been used to model heat transfer locally within selected intersecting geometries, and thus to examine the average heat transfer coefficient compared to that predicted by the well-known Dittus-Boelter correlation and other investigators. Insight gained from the CFD predictions enables a first-order estimate of the impact of adding intersections to the convective cooling performance of these advanced cooling configurations. Results show that even an imperfectly machined (i.e. partial) intersection can provide a significant improvement to heat transfer as well as enhanced loss.

Abstract:
This paper presents a systematic approach for identifying feasible robot base placement regions within a workcell, and evaluating performance of industrial robots for the design of mobile industrial robotic system to perform collision-free automated welding of large intersecting cylindrical pipe structures. First, a mathematical model based on the geometry of intersecting cylindrical pipes is used to generate the welding task and torch orientation. Next, collision detection is performed using line geometry and possible robot base positions are identified and rated according to the manipulability measure. This yields a graph of feasible robot base placement regions that perform collision-free welding rated in terms of its dexterity. Finally, a task metric based on kinematic measures to evaluate the robot’s performance is proposed and discussed. An implementation of this approach for evaluating two different 6R industrial robots for welding jack-up rig structures was used as examples. This technique will also be applicable for designing mobile robotic system for tasks other than welding which may require trajectory-following end-effector motion uninterrupted by objects within the workspace such as painting, taping, blasting, cutting, etc.

Abstract:
This is the second part of a two-part paper presenting an efficient parametric approach for updating the in-process workpiece represented by the Z-map. With the Z-map representation, the machining process can be simulated by intersecting z-axis aligned vectors with cutter swept envelopes. In this paper the vector-envelope intersections are formulized for the toroidal section of a fillet-end mill which may be oriented arbitrarily in space. For a given tool motion a toroidal surface generates more than one envelope. In NC machining because the torus is considered as one of the constituent parts of a fillet-end mill, only some parts of the torus envelopes, called contact envelopes, can intersect with Z-map vectors. In this paper an analysis is developed for separating the contact-envelopes from the non-contact ones. When a fillet-end mill has an orientation along the vertical z-axis of the Cartesian coordinate system, which happens in 2 1/2 and 3-axis machining, the number of intersections between a Z-map vector and the swept envelope of a toroidal section of the fillet-end mill is maximum one. For finding this single intersection point one of the numerical root finding methods, i.e. bisection, can be applied to the nonlinear function obtained from vector-envelope intersections. On the other hand when a fillet-end mill has an arbitrary orientation, the number of intersections can be more than one and therefore the numerical root finding methods cannot be applied directly. Therefore for addressing those multiple intersections, a system of non-linear equations in several variables, obtained by intersecting a Z-map vector with the envelope surface of the toroidal section of a fillet-end mill, is transformed into a single variable non-linear function. Then developing a nonlinear root finding analysis which guarantees the root(s) in the given interval, those intersections are obtained.

Abstract:
Abstract This paper describes a potential field approach to robot path planning into cavities defined by B-splines. It discusses existing methods, and describes the development of a Voronoi tree using intersecting hodographs. The Voronoi tree is similar to the Voronoi diagram in that it is maximally distant from all objects in the robot’s environment, but the Voronoi tree is developed for cavities modeled by splines. By adding a potential field to the robot manipulator, a robot path can be found by seeking the manipulator position with the minimum value of the potential function. This position as defined by the potential field is also maximally distant from cavity walls. Results with the potential field method are discussed and conclusions are drawn.

Abstract:
This two-part paper presents an efficient parametric approach to updating workpiece surfaces represented by the Z-map vectors. The methodology is developed for up to 3 1/2 1/2-axis machining in which a tool can be arbitrarily oriented. In calculations the Automatically Programmed Tool (APT)-type milling cutters represented by the natural quadrics, planar and the toroidal surfaces are used. The machining process is simulated through calculating the intersections between the Z-map vectors and the tool envelope surface which is modeled by using a tangency function. Part 1 of this two-part paper presents the methodology for the cutters with natural quadrics and planar surfaces. For those surfaces intersection calculations are performed analytically. The geometric complexity of a torus is higher than those of the natural quadric and planar surfaces. Furthermore if the torus has an arbitrary orientation then the intersection calculations for the torus present great difficulties. In NC machining typically a torus is considered as one of the constituent parts of a cutter. In this case only some parts of the torus envelopes, called contact-envelopes, can intersect with Z-map vectors. For this purpose in Part 2 of this two-part paper an analysis is developed for separating the contact-envelopes from the non-contact envelopes. Then a system of non-linear equations in several variables, obtained from intersecting Z-map vectors with contact envelopes, is transformed into a single variable non-linear function. Later using a nonlinear root finding analysis which guarantees the root(s) in the given interval, those intersections are addressed.

Abstract:
Abstract The modern engineering technologies of Computer-Aided Design (CAD), Computer-Aided Engineering (CAE) and Computer-Aided Manufacturing (CAM) are ubiquitous in engineering design. They are focused on creating, analyzing, and fabricating objects represented as geometric models. Historically, these technologies developed independently, such that their geometric representations are customized to the needs of the technology. As a result, combined use of these technologies has led to differences in data structures, file formats, software constraints, and user knowledge and practice, requiring translation of representations between systems to support interoperability. Complicating this situation is the approximate nature of modeling operations in CAD systems, which can result in gaps at the boundary curves between mating trimmed surfaces of a model. The research presented here is aimed at removing the gaps between trimmed surfaces, resulting in a “watertight” model that is suitable for use directly by downstream applications. A three-step algorithm is presented that includes analysis of the parametric space of the trimming curves, reparameterization to create a global parameter space, and reconstruction of the intersecting surfaces to ensure continuity at the trimming curve.

Abstract:
The planarity of graphs is one of the key sections of graph theory. Although a graph is an abstract mathematical object, most often it is graph visualization that makes it easier to study or develop in a particular area, for example, the infrastructure of a city, a company’s management or a website’s web page. In general, in the form of a graph, it is possible to depict any structures that have connections between the elements. But often such structures grow to such dimensions that it is difficult to determine whether it is possible to represent them on a plane without intersecting the bonds. There are many algorithms that solve this issue. One of these is the gamma method. The article identifies its problems and suggests methods for solving them, and also examines ways to achieve them.
