AbstractA generically embedded real submanifold of codimension two in a complex manifold has isolated complex points that can be classified as either elliptic or hyperbolic. In this paper we show that a pair consisting of one elliptic and one hyperbolic complex point of the same sign can be cancelled by a $\mathcal {C}^{0}$small isotopy of embeddings.

AbstractThe only stable singularities of a real map-germ $f:{\mathbb R} ^n\to{\mathbb R} ^{2n}$ are isolated transverse double-points. All ${{\cal A}}$-simple germs f have a deformation with the maximal number d(f) of real double-points (this is a partial generalization to higher n of the result of A'Campo [1] and Gusein-Zade [13] that all plane curve-germs have a deformation with δ real double points, with the extra hypothesis of ${{\cal A}}$-simplicity). The proof of this result is based on a classification of all ${{\cal A}}$-simple orbits.

Existing Nonlinear Anisotropic Diffusion (NAD) methods in image smoothing cannot obtain satisfied results near singularities and isolated points because of the discretization errors. In this paper, we propose a new scheme, named Enclosed Laplacian Operator of Nonlinear Anisotropic Diffusion (ELONAD), which allows us to provide a unified framework for points in flat regions, edge points and corners, even can delete isolated points and spurs. ELONAD extends two diffusion directions of classical NAD to eight or more enclosed directions. Thus it not only performs NAD according to modules of enclos

We initiate the study of a class of real plane algebraic curves which we call expressive.

This concept can be viewed as a global version of the notion of a real morsification of an isolated plane curve singularity. We prove that a plane curve C C is expressive if (a) each irreducible component of C C can be parametrized by real polynomials (either ordinary or trigonometric), (b) all singular points of C C in the affine plane are ordinary hyperb

In the special case of a non-isolated real hypersurface singularity f, with a one-dimensional critical locus, we relate the signature on the Jacobian module I/Jf to the Euler characteristic of the positive and negative Milnor fibre, generalising the result for isolated critical points.

This unsupervised classifier is free of any external control mechanism. Its self-organizing (SO) dynamic is governed by the gradient descent (GD) theory in cooperation with a competition mechanism based on Lotka–Volterra competitive excl

Choreographic history isolates a relatively recent—and probably distinctively Western—institution against a background murmur of millennia of festivals, trance, apotropical rituals, and cures for the possessed. Choreographic spectacle separates dances from their social or religious effects, depriving the participant of any real involvement with what they see. This Western inventi

Abstract:
AbstractTwo chassis components were developed at the Technische Universität Darmstadt that are used to isolate the body and to reduce wheel load fluctuation.The frequency responses of the components were identified with a stochastic foot point excitation in a hardware-in-the-loop (HiL) simulation environment at the hydropulser. The modelling of the transmission behaviour influence of the testing machine on the frequency response was approximately represented with a time delay of $$10\,\mathrm {ms}$$ 10 ms in the frequency range up to $$25\,\mathrm {Hz}$$ 25 Hz . This is considered by a Padé approximation. It can be seen that the dynamics of the testing machine have an influence on the wheel load fluctuation and the body acceleration, especially in the natural frequency of the unsprung mass. Therefor, the HiL stability is analysed by mapping the poles of the system in the complex plane, influenced by the time delay and virtual damping.This paper presents the transfer from virtual to real quarter car to quantify the model uncertainty of the component, since the time delay impact does not occur in the real quarter car test rig. The base point excitation directly is provided by the testing machine and not like in the case of the HiL test rig, the compression of the spring damper calculated in the real-time simulation.

Abstract:
This chapter argues that although Engels successfully encouraged Marxism to adopt Hegelian metaphysics as its philosophy of historical change, Marx himself can be absolved of charges of teleology and political gradualism. Guided by Galvano Della Volpe’s reconstruction of Marx’s thought, it is shown that Marx’s methodology of real abstraction stands in stark contrast to Hegel’s speculative dialectic. Capital may contain isolated chapters that suggest teleological historicism, but taken as a whole the text points to the need for a conscious break from capitalism informed by economic analysis. The chapter concludes by contrasting Marx’s political statements about communist transformation with Kautsky’s and Lenin’s views on the post-revolutionary transition period.

Abstract:
The expansion of empire into the Pacific Ocean took place in the age of enlightenment as well as the age of sail. It coincided with new metropolitan methodologies for the acquisition and ordering of natural history, and speculation on the natural world’s relation to changing human and social worlds. Islands, in this context, were always more than just refuelling and repair points. In Oceania, these islands were small, self-contained, and often isolated enough to make them ideal spaces, or so it would seem, for seaborne natural historians. In Europe, Enlightenment philosophers had invented mythic islands. Now these were overlaid with, and interrupted by, rapidly accumulating knowledge of actual island-dwellers and their environments. This chapter explores the meeting point of Enlightenment mythic and literary islands with real encounters in the Sea of Islands, from James Cook’s voyages in the 1770s to T.H. Huxley and John MacGillivray’s in the 1840s.

Abstract:
Risk assessment for human health and ecosystems by exposure to chemicals is an important process to aid in the mitigation of affected areas. Generally, this process is carried out in isolated spots and therefore may be ineffective in mitigating. This chapter describes an architecture of a multi-agent system for environmental risk assessment in areas contaminated as often occur in mining, oil exploration, intensive agriculture and others. Plan multiple points in space-time matrix where each agent carries out exposure assessment and the exchange of information on toxicity, to characterize and classify risk in real time. Therefore, it is an architecture model with multi-agent that integrates ontology by semantic representation, classifies risks by decision rules by support vectors machines with multidimensional data. The result is an environment to exchange information that provides knowledge about the chemical contamination, which can assist in the planning and management of mitigation of the affected area.

Abstract:
This chapter applies some of the concepts presented earlier to transformations brought about by nucleophilic additions to aldehydes, ketones, imines, and nitriles. It begins by the addition of primary and secondary amines, thus reversibly producing imines and enamines, and points out that imines are involved in the biosynthesis of alkaloids, amino acids, etc. with the aid of enzymes. Chiral imines and enamines are useful in organocatalysis. Oxygen or sulfur nucleophiles are used to prepare acetals or their thio equivalents and their use as protecting groups is discussed. Addition of carbon nucleophiles produces alcohols, a reaction that has stereoelectronic requirements that are modelled by the Felkin–Anh and Cram chelate models. The preparation, structure in ether solvents, and the use of organomagnesium (Grignard) and organolithium reagents are discussed, and some chemoselectivity issues are presented. The Wittig and the Horner–Wadsworth–Emmons reactions are used to prepare olefins, and the modifications that produce E and/or Z alkenes are discussed from a mechanistic point of view. Throughout the chapter real-world results are presented, often mentioning the conditions actually employed, along with isolated yields. Some of the main workers involved in the introduction of the methodologies are cited in brief biographical abstracts.

Abstract:
The application of intelligent engine room systems in the field of ship automation is becoming increasingly important. This review focuses on the research of engine room fault diagnosis in ships, proposes the technical system of intelligent engine room systems, and discusses the research content of engine room condition monitoring technology and fault diagnosis technology. The paper points out that industrial intelligence is one of the main directions of industrial technological development, and emphasizes the intelligent transformation in the design and manufacturing of intelligent ships. The paper further introduces the engine room as the core of a ship, and emphasizes the importance of its operational efficiency for overall performance. However, most of the current domestic ship engine room automation systems are closed and isolated, unable to upload engine room equipment data in real time, and cannot meet the requirements of ship classification societies. Therefore, fully sensing the status of engine room equipment and using big data analysis and intelligent diagnostic technology to improve engine room operational efficiency become the future development direction.

Abstract:
Abstract This chapter concerns James’s idea of a field of consciousness, a moving and shifting sense of exploratory experience beyond the restrictive ideas of a ‘self’. For James the self, and its consciousness, is not a separate, isolated substance but is a vibrating field opening out into the surrounding world. The field always has a centre, a focus or nucleus. Around it, less conscious, is a periphery, a fringe or halo or margin. But the field is dynamic and can shift: the margin—what is at the back of the mind or at the corner of the eye—may come more into focus, permeate the nucleus, and change the centre of gravity by acts of new realization and discovery. This is how the human mind is truly mobile. Our sense of the actual is surrounded by other possibilities – not merely other points of view but changes in the very topography of a person’s being. The chapter gives examples of mental experience on the fringes of consciousness: the virtual, the implicit, the potential and the possible. Thought is what makes human beings more than merely automatic: it exists in between stimulus from without and response from within, to provide a pause and make a difference. To James, the movement from sub-conscious to conscious, from fringe to nucleus, was thought itself at its very best. The pragmatic question is always What does this mean as applied to real life? As in chapter 3, particular human examples are given of ‘James, not Pure but Applied’: intellectual thought and artistic creativity translated into ordinary life.

Abstract Zhuangzi, also known as Chuang-tzu, very probably was a real person, who lived in the fourth century BCE.The book to which his name is attached has accretions that stamp it as the work of many hands. Scholars sometimes isolate within the Zhuangzi (Chuang-Tzu) what are called the “Inner Chapters” (chapters I through 7), which are viewed as a core early text and also as exceptionally vivid presentations of the point of view of the book. That point of view may not be entirely evident right away to the first-time reader. The book is fanciful, and there are many digressions and changes of tone. The overall impression may be of someone who is clever and is fooling around. There are works (the eighteenth century novel Tristram Shandy is an example) whose “unity” is their disunity, their lack of discursive integration; and the Zhuangzi may seem to be one of these works. Nevertheless, I wish to suggest that at least the Inner Chapters are in their way highly integrated, with no words wasted and no line of thought as random as it may look. There is a consistent set of philosophical positions and implicit arguments for these. Read right, the Zhuangzi is real philosophy--although it also is a lot of fun and is a strangely beautiful book.

Integrated stingers have been developed to improve measurement results. The relative importance of the rotational components is investigated. The blocked impedance method has been used to couple the subframe to the car body using measured mobilities via two isolators out of four. The sound sensitivity is measured directly for the coupled system and compared with the total sum of the calculated transfer path components which are calculated with measured mo

Abstract:
An investigation has been carried out in order to define the process of rotating stall inception in a low speed, low hub-tip ratio fan. Based on elementary cascade analysis, the fan would be expected to stall from the root, however, considerable experimental evidence indicates that tip stall is more frequently incurred. Although the analysis has been undertaken for a specific fan it is considerd to be representative of a broad range of machines. The analysis has involved two primary considerations, first the effect of streamtube contraction which has been studied theoretically and secondly rea
