    Notes: Systems of coupled oscillators possess a wealth of interesting and useful nonlinear dynamical phenomena. Arrays of coupled oscillators have been used to model complicated biological and neural activity, and have proved useful in power-combining applications. The analysis of such arrays is difficult, and has generally been restricted to the case where all oscillators are synchronized to a common frequency through the phenomenon of injection locking. When the natural (or free-running) frequencies are very widely distributed, this mutual synchronization is impossible, and the system can exhibit chaotic behavior. However, by carefully choosing the frequency distribution, a stable mode-locked state can be established in which the collective output of the oscillator array consists of a train of pulses, similar to a mode-locked laser. Due to the different physical mechanisms involved, and due to a spatial as well as spectral separation of the oscillators, the mode-locked array exhibits new phenomena not present in mode-locked lasers. A theory describing the coupled-oscillator dynamics is developed to explore these new effects, and the theory is amply supported with empirical evidence obtained with a linear array of Gunn diode oscillators operating at 11 GHz.

    Notes: This article describes an experimental apparatus for free-space mm-wave transmission measurements (spectroscopy). GaAs nonlinear transmission lines and sampling circuits are used as picosecond pulse generators and detectors, with planar monolithic bowtie antennas with associated substrate lenses used as the radiating and receiving elements. The received pulse is 270 mV amplitude and 2.4 ps rise time. Through Fourier transformation of the received pulse, 30–250 GHz measurements are demonstrated with ≤0.3 dB (rms) accuracy.

    Realization of high tunability barium strontium titanate thin films by rf magnetron sputtering (1999)

    Notes: Ferroelectric thin films are currently being used to develop tunable microwave circuits based on the electric-field dependence of the dielectric constant. (Ba0.5Sr0.5)TiO3 (BST) films prepared by sputtering on Pt/TiO2/SiO2/Si substrates are found to exhibit a capacitance change (tunability) of nearly 4:1. Higher tunability has been attributed to the (100) texturing of the BST films and is a result of the biaxial tensile stress imposed by Si on BST making the polar axis oriented in plane. Electrical characterization shows that the dielectric permittivity increases with increase in film thickness (up to ∼200 nm). © 1999 American Institute of Physics.

    The Comic Sense of Saint-John Perse (1990)

    Notes: Humour is a minor element in the work of Saint-John Perse, and has often been overlooked by critics. His comic sense is nevertheless characteristic of his poetic sensibility. Comedy arises in his work from uses of inappropriate register (too solemn or too frivolous), inapt speech-acts (self-defeating claims), inappropriate comparisons (with incongruities of scale or importance), and, less frequently, puns or the narration of incongruous acts (trivial or perverse). These procedures are thematically significant; they depend on clashes between three types of valued experience: natural and corporeal animation, overwhelming intensity of sensation, and sharing in community; the clashes sometimes allow a tolerant acceptance of the opposing elements, but sometimes reveal a satiric rejection of one of them. The satiric attitude tends to lead to elimination of the affected element from the text, whereas accep-tant humour tends to lead to the maintenance of both elements. Perse's humour expresses his acceptance of the irrational and his love of free and adventurous living.

    Thematic Construction in “le Roi des aulnes” (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Orbis litterarum 36 (1981), S. 0 
    Details
    ISSN: 1600-0730
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Linguistics and Literary Studies
    Notes: Tournier's le Roi des aulnes is based on four themes, most clearly apparent in the final scenes: Obsession, Possessiveness, Sacrifice and the Apocalypse. These themes are often manifest through repetition, which makes for readability and, especially in the form of memory, for a sense of coherent character; but they also show much inventiveness and allow many cultural allusions to be integrated into the work. The themes emerge gradually and involve new groupings of textual elements, so as to permit the formation of new interpretations and to afford a sense of sudden enlightenment; such development leads to increasing complexity of texture. There are also characteristic changes in the manifestation of the themes: they progress from imagination or symbol to reality; they increase in seriousness; and they increase and decrease in moral value. The four themes do not appear with equal frequency but are intertwined so as to appear interdependent and create significant ambiguities. This thematic elaboration requires the reader to enter into the perspective of an abnormal character which corresponds, however, to aspects of symbolist literature.

    Eluard's Female Landscape (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This paper seeks to place the image of woman as landscape, frequent in Eluard, in the structure of the poems in which it appears. The image most often indicates a transition within the poem from a state of personal identity to one of impersonality; but this basic structure is subject to systematic modifications affecting the character of the image and of the states preceding and succeeding it; thus poems may imply a range of different values and may present the relationship of speaker and other people or outside world more or less positively. Forms of the image may also occur initially, so that the remainder of the text shows either a gradual development of the impersonal state they imply or the overcoming of an obstacle to it; or they may occur finally, either as a surprising closure or as a reinforcement of a previous occurrence of the image in some form. In thus selecting among the imagined implications of the image, Eluard imposes an order on his fascination with the body in space.

    Thematic Structures in Saint-John Perse's Amers (1983)

    Notes: Amers is characterised by elaborate verbal repetition comparable to musical structure. This both makes clear the fundamental themes of the poem and enriches the sense of particular passages in one of four ways: (i) the passage may be shown to express an attitude considered normal within the work, as with references to praise or purity: such attitudes may be complex or ingenious, as with the ideas of the aubain, the fourbe, the étrille; (ii) the passage may be shown to express a paradoxical or uncertain sense, as with references to silk or offence; (iii) the passage may illustrate radically ambivalent conceptions, as with references to strangers, the harvest and especially to boundaries; (iv) the passage may articulate the progress of the text towards greater solemnity, towards harmony and concilation, or towards temporal colosure.

    Notes: Comment on Eluard's poetry has tended to concentrate on single images. the present study aims at showing that the images in the poems of Capitale de la douleur are combined according to certain regular patterns; they represent certain attitudes to the outside world, which normally are stated in a specific sequence, although certain stages of this sequence may be omitted or dealt with only briefly and there may be some variation, occasionally, of the basic order. the fundamental sequence is (1) immersion in the world; (2) awareness of the otherness of the world; (3) conflict and alienation; (4) assertion of the individual; (5) failure of the individual; (6) unity, love and imagination.

    Bellow's passionate speech (2002)
    Copenhagen : Munksgaard International Publishers

    Notes: Saul Bellow's novels are often considered to be didactic in the sense that the author expresses his judgement of the modern world through the views of his characters. This paper argues that the judgement expressed is extremely unclear and that the characters are often presented as very unreliable guides. The characters are concerned with self-invention or self-justification – which may often imply a criticism of the contemporary world – and they appeal to the reader above all through the rhetorical energy of their speech, which distinguishes the individuals from a mass society, and is also subject to ironic or comic treatment on the part of the author. This rhetoric is conveyed in some of the novels through first person narrative, in which case much of the concern of the narrators is to establish an image of themselves conspicuously in the eyes of the reader. Other novels are written in the third person; in these the narrators' perspective may still be close to that of a central character, but there is also a more explicit recognition of the variety of possible judgements of characters' attitudes and conduct. Overall it is argued that Bellow's work is heteroglossic in nature and characterised by a dramatic sense of personality in which the individual forms himself by choosing a role.

    Auden's Study of Time (1999)

    Notes: W. H. Auden's concern with the theme of time is apparent throughout his work. He considers attitudes to time to be a crucial aspect of personal and national character, and opposes the temporal world of personal morality to the spatial world of complacency. But his attitude is ambivalent; he regards time both as loss and erosion and also as growth towards fulfilment. He is particularly concerned with the cycle of the seasons, which he sometimes sees as an alienating inertia. Within the poems three structures are identified which focus on the relation of the moment to change in time, and especially formulate this in terms of the co-presence of memory and will: these are the moment of peace located in time; the creation of memory; and the assertion of process. It is argued that the view of time implicit in these structures is analogous to the temporal organisation of music, and that Auden's conception of time should be thought of as aesthetic as well as moral or religious.
