Abstract Modern ship’s navigation support systems relay mainly on GNSS technology, as prime source of position. The advantages of such solution are obvious and undeniable. On the other hand in critical situations the dependency of the one system presents a great deal of risk. Taking above into consideration the idea of building GNSS independent Pilot Navigation and Docking System (PNDS) was put into practice. PNDS utilizes the range measurements between laser head and ship’s side to determine the ship’s horizontal plane presented on the screen. The study comprises the case in which three networked rangefinders were deployed on the berth side in a line. Such location of sensors causes uncertainty in determining of ship’s outline contour and speed in relation to assigned coordinate reference system. The final algorithm presented in the article, taking into account all underdetermined conditions, has been tested in PNDS system constructed in Maritime University in Szczecin.

This thermoscope is founded on the change produced in the magnetic moment of a steel magnet by change of temperature. Several different forms suggest themselves: the one which seems best adapted to give good results is to be made as follows:—(1.) Prepare an approximately astatic system of two thin, hardened steel wires, r b, r′ b′, each 1 cm. long, one of them, r, b, hung by a single silk fibre, and the other hung bifilarly from it, by fibres about 3 cms. long, so attached that the projections of the two, on a horizontal plane, shall be inclined at an angle of about ·01 of a radian (or ·57°) to one another.

This article addresses a lack in both queer and anti-neoliberal political critique: on the one hand, queer theoretical approaches neglect questions of production and class, on the other hand economical analyses all too often ignore the question of sexuality. The author argues that this blank is symptomatic for the current regime that reins the construction of sexual identities and he asks why it is so difficult to do otherwise. While religious fundamentalists, nationalist and racists unanimously reject both homosexuality and neoliberalism, official neoliberal discourse in the European Union includes tolerance of homosexuality within its list of allegedly European values. In Germany and in the Netherlands, right wing liberal policies thus give anti-homophobic struggles a nationalist and racist stance, constraining them to co-opt neoliberalism, consumerism, nationalism and racism. Finally the article discusses whether the notion of precariousness could help to link economic and sexual concerns such a way that the dialectics of individuality and risk taking in neoliberalism are illustrated.

1. The purpose of this study was to examine the effect of changing initial stance conditions on the postural response of the cat to horizontal plane translations of the support surface. Cats were trained to stand, unrestrained, on a moveable force platform. The platform was translated linearly in each of 16 directions in the horizontal plane, with a ramp-and-hold displacement. The animal's response was quantified in terms of the forces exerted at the ground. The trajectory of the center of mass (CoM) was computed from the forces. 2. Stance length was varied along the longitudinal (sagittal) axis by adjusting the distance between the forepaw and hindpaw force plates. Translation perturbations of the platform were recorded at stance distances varying from 66 to 110% of the preferred stance distance. 3. Changing stance distance had a significant effect on the amplitude and direction of the active forces exerted by the cat both during quiet stance and during the response to platform translation. At long stance distances, each limb exerted a force outward, along the diagonals during quiet stance. The response to translation was characterized by an invariance in the direction of force exerted against the ground, a strategy that was described previously. At short stance distances, quiet stance forces were more laterally directed. The force constraint strategy was usually not observed for the response to translation. Nevertheless, the cats were equally effective at all stance distances in restoring the position of the center of mass after translation of the support surface. 4. There was no discrete boundary between the presence and absence of the force constraint, suggesting that the strategy for exerting forces against the support surface is characterized by a continuum of response, from a bimodal, or anisotropic distribution of force vectors on the one extreme, to a uniform, or isotropic distribution on the other. Arguments are developed to suggest that the force constraint strategy may be useful in stabilizing the vertebral column during the response to platform translation, to allow linear translation of the CoM rather than bending of the trunk.

Political Decision Making

This chapter explores the ways in which gender shaped the respective approaches to political decision-making by the marquis and his wife. I argue that while the delegated nature of her authority encouraged Isabella to keep her emotions strictly in check and to be prudent in a diplomatic setting, Francesco was far more erratic. On the one hand, he adopted strategies of temporizing, prevarication, and swift changes of allegiance to hedge his bets politically, seen by contemporaries as intrinsically female vices, on the other, he indulged in reckless and competitive behaviour designed to display his masculine courage and princely disdain for caution. Together the couple evaded the dangers posed by the second French descent and the fall of Milan to Louis XII, but it was Isabella’s prudence that neutralized the ill-considered risk-taking of her husband.

AbstractThe present paper investigates how theBridge Budapest, a CSR organization founded by leading Hungarian IT startups, attempts to shape the values of Hungarian society towards capitalism in general, and towards entrepreneurship in particular. In my paper I argue that the central aim of the organization is to facilitate Hungary’s catching up with the core capitalist countries through the transformation of the attitudes and the ideologies surrounding capitalism in the Hungarian context, i.e.the local spirit of capitalism. This consists, on the one hand, of restoring the legitimation of some of the core institutions of capitalism, such as the enterprise and the entrepreneur, and of confronting the risk-taking, innovative and ethical figure of the entrepreneur hero with the provincial figure of the ‘postcommunist cheater’. On the other hand, it also consists of propagating a new management of work that aims to produce self-controlling and self-motivating employees. In the narrative of Bridge Budapest IT companies appear as the perfect moral and economic subjects – the bearers of the new spirit of capitalism – that have the expertise to offer solutions to the problems of Hungarian society, and around which the local capitalism should be built.

To perform automotive maintenance, there are many makeshift ways of lifting and holding a vehicle including the use of forklifts, overhead hoists and cranes, jacks of every kind, jack stands and various ramp systems. When automobiles fall from these devices, the causes are usually obvious and we disapprovingly tolerate the risk taking. On the other hand, when a vehicle falls from a dedicated automotive lift, the accident is entirely unacceptable. This paper examines several hidden dangers associated with a particular class of lifts that are “frame engaging.” Various styles of these lifts use four cantilevered arms to elevate and support vehicles on adapter pads positioned on the arms’ free ends. If the vehicle slides off of one or more pads, it usually falls catastrophically. The cantilevered arms, when raised, are supposed to be restrained against rotation in a horizontal plane. When restrained, the arms provide a robust structural system for resisting horizontal workplace forces that tend to slide vehicles off the pads. The arms maintain the horizontal locations of the adapters by developing bending and axial planar resistance. If, on the other hand, the arms are free to pivot due to sloth or poor design, their structural behavior is dramatically transformed. The planar bending resistance of the arms completely disappears and they become direct stress diagonal truss members; the vehicle itself unwittingly becomes the truss’ tension chord. The appearance of the fixed and pivoting systems is the same; however, the truss action magnifies the horizontal forces acting on the adapter pads increasing the slip probability. Indeed, depending on the orientation of the pivoting swing arms, any finite horizontal force applied to a vehicle may lead to an unbounded tangential “slide-out” force. This is, of course, a theoretical possibility, not a practical reality.

This paper discusses problems with labelling plant structures in the context of attempts to create a unified Plant Structure Ontology. Special attention is given to structures with mixed, or doubtful identities that are difficult or even impossible to label with a single term. In various vascular plants (and some groups of animals) the structural categories for the description of forms are less distinct than is often supposed. Thus, there are morphological misfits that do not fit exactly into one or the other category and to which it is difficult, or even impossible, to apply a categorical name. After presenting three case studies of intermediate organs and organs whose identity is in doubt, we review five approaches to categorizing plant organs, and evaluate the potential of each to serve as a general reference system for gene annotations. The five approaches are (1) standardized vocabularies, (2) labels based on developmental genetics, (3) continuum morphology, (4) process morphology, (5) character cladograms. While all of these approaches have important domains of applicability, we conclude that process morphology is the one most suited to gene annotation.

Für den Kunstkritiker Julius Meier-Graefe (1867-1935) haben Bilder eine ganz eigene Logik, die sich nicht in Sprache übersetzen lässt. Ausgehend von dieser Prämisse denkt Meier-Graefe die Kunstgeschichte als interpiktoriales, sich selbst regulierendes Geflecht und bedient sich zur Vermittlung von Bildern selbst auf gleich zweifache Weise einer bemerkenswerten Bildlichkeit – sei es qua Plädoyer für oder Einsatz von Reproduktionen, sei es qua einer der ikonischen entsprechen- den somatischen Deixis: Indem er sich selbst in seiner physischen Reaktion auf ein Werk(erlebnis) Tableauartig in Szene setzt, kehrt er die Wirksamkeit von Bildgefügen hervor, macht sie visuell nachvollziehbar und aktualisiert deren Potential. Diesen Vorstellungen und Vorgehensweisen liegt, so die These des Beitrags, die Erfahrung musealer Präsentation und Rezeption zugrunde. Entwickelt wird eine »praktische Ästhetik«, die auch für aktuelle Interpiktorialitätsdebatten diskussionswürdige Ansätze bereithält. <br><br>In the opinion of the art critic Julius Meier-Graefe (1867-1935), pictures have a specific logic which is impossible to translate into spoken language. Given this premise, Meier-Graefe develops a specific theory of how art history constructs itself as an interpictorial, self-regulated reference system. Furthermore, in order to convey works of art, he operates with pictures and images in a remarkable way: on the one hand, he makes specific use of reproductions, on the other hand, he communicates via body language that parallels the iconic deixis: By describing and presenting himself in his texts in the physical act of perception and/or reception, he turns himself into a tableau and makes the effect as well as the potential of the artwork visible. The basis of these ideas and methods seems to be the modern experience of museum presentation and reception. Meier-Graefe develops a kind of “practical aesthetic” which can enrich the current debates on interpictoriality.

Imagination works upon desires and needs in a variety of ways. Different sensibilities will concentrate upon different of its operations and neglect - or even ignore - others. Thus Rousseau (and in some ways Plato, as we shall see) takes a very gloomy view of the uses of imagination. He sees only its dark aspect, under which it is a prime source of wretchedness:It is imagination which enlarges the bounds of possibility for us … and therefore stimulates and feeds desires by the hope of satisfying them. But the object within our grasp flies quicker than we follow; when we think we have grasped it, it transforms itself and is again ahead of us … Thus we exhaust our strength, yet never reach our goal, and the nearer we are to pleasure, the further we are from happiness ... The world of reality has its bounds, the world of imagination is boundless; as we cannot enlarge the one, let us restrict the other; for all the sufferings which really make us miserable arise from the difference between the real and the imaginary.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.
