A quadratic B-spline finite element method for the spatial variable combined with a Newton method for the time variable is proposed to approximate a solution of Benjamin-Bona-Mahony-Burgers (BBMB) equation. Two examples were considered to show the efficiency of the proposed scheme. The numerical solutions obtained for various viscosity were compared with the exact solutions. The numerical results show that the scheme is efficient and feasible.

The mourning and grief practice richly registered in Shakespeare's Hamlet is one of the abiding themes that critics have been fascinated with. This paper attempts to take a fresh look at the issue by building its arguments on Benjamin's insight that the modern art (mechanically) reproducing the exhibition value brings about the destruction of the ritual value and favors the conditions of melancholy. Instead of taking for granted that Hamlet's performance of grief is fundamentally different from those of other characters such as Gertrude, Ophelia, and Laertes, this paper argues that Hamlet's performance comes to be recognized masculine and different from others, only because he presents himself to be so through his theatrical performance as well as his princely power that the subjects (others in the story) ought to ascribe to. To prove this point, this paper closely analyzes Hamlet's rhetorics and the ways he constructs his mourning self, which is emblematic of the shift in art history that Benjamin has characterized with the terms of "ritual value" and "exhibition value." In conclusion, this paper suggests that Shakespeare's Hamlet marks the change of the historical horizon, a permanent removal from the past in which the ritual value had been once protected, pushing us to a new age to live with melancholy and the disconnection from things and their muted language.

William Carlos Williams discovers important sources of inspiration in the revolutionary avant-garde movements, in particular, Dada and Surrealism and attempted to embody the innovations in them in his poetic theory and practice. Williams's passion to create an indigenous American poetic work is compatible with his Dadaist experimentation with objets trouvés. Williams pays deep attention to objets trouvés, physical objects and marginalized people he comes across and transcribes his observations with poetic words freed from their instrumental contexts. In his characteristic poems written in the 1920s and 1930s, Williams records the social ruination and his task to give voice to the conflictual and fragmentary character of modernity is pursued through the Surrealist formulation of montage. In the Surrealist formulation of montage, the dialectical image is a central trope for reading the myth of modernity; it is positioned as both subject and object in the historiographic narratives of Walter Benjamin and Williams. As Benjamin tries to obliterate all traces of the author in the Arcades Project, Williams's montage poems like Spring and All only disperse argument into materialistic, dialectical images. The dialectical image in Williams's poetics becomes an organon of historical awakening so that truth can emerge from an unmediated juxtaposition of "things."

Walter Benjamin's unique concept of the aura is mainly presented in his three essays, Little History of Photography(1931), The Work of Art in the Age of Mechanical Reproduction(1935-1939), and On Some Motifs in Baudelaire(1939), whereas the studies on this concept are principally conducted on the basis of the first two essays. But considering Benjamin elaborated the concept through Baudelaire studies, the aura needs to be reexamined on the axis of "On Some Motifs in Baudelaire". He approached Baudelaire studies in one of the essential items for The Arcades Project at first. These studies acquired a new prospect soon after he mapped out these studies for an independent book in 1938. His Baudelaire studies come to fruition in On Some Motifs in Baudelaire, written one year after The Paris of the Second Empire in Baudelaire(1938). For Benjamin, Baudelaire is not only a poet who sharply testified to the age of the decay of aura, but also the one who elaborated new poetic motifs such as the metropolis, the crowd: the poet searched for his poems in the crowd of the metropolis, by accepting as poetic nourishment all sorts of experiences of the impact of daily occurrunces in Paris. In On Some Motifs in Baudelaire, the aura is defined as the response of a gaze, that is, the capability to gaze on something. It is principally a poetic capacity to give the capability of opening the eyes to an animal, or even to an inanimate object. If a gaze is responded by the other for which the gaze is placed upon, we experience the other's own aura. The media of the mechanical reproduction (such as the photography, the film) give rise to the decay of aura, because the expectation of returning one's gaze becomes frustrated from the outset.

In this paper, we discuss a reduced-order modeling for the Benjamin-Bona-Mahony-Burgers (BBMB) equation and its application to a distributed feedback control problem through the centroidal Voronoi tessellation (CVT). Spatial distcritization to the BBMB equation is based on the finite element method (FEM) using B-spline functions. To determine the basis elements for the approximating subspaces, we elucidate the CVT approaches to reduced-order bases with snapshots. For the purpose of comparison, a brief review of the proper orthogonal decomposition (POD) is provided and some numerical experiments implemented including full-order approximation, CVT based model, and POD based model. In the end, we apply CVT reduced-order modeling technique to a feedback control problem for the BBMB equation.

Experimental investigation of nonlinear instability of deep-water wave train is performed. Two-dimensional Benjamin-Feir type wave instability and breaking are observed at wave steepness between 0.19 and 0.25 and three-dimensional instability and breaking at wave steepness greater than or equal to 0.31. At the same wave steepness, shorter waves with smaller amplitude are more unstable, with earlier occurrence of breaking, than long waves with large amplitude.

A numerical scheme is proposed to control the BBMB (Benjamin-Bona-Mahony-Burgers) equation, and the scheme consists of three steps. Firstly, BBMB equation is converted to a finite set of nonlinear ordinary differential equations by the quadratic B-spline finite element method in spatial. Secondly, the controller is designed based on the linear quadratic regulator (LQR) theory; Finally, the system of the closed loop compensator obtained on the basis of the previous two steps is solved by the backward Euler method. The controlled numerical solutions are obtained for various values of parameters and different initial conditions. Numerical simulations show that the scheme is efficient and feasible.

A midline or median cleft lip is rare, and a midline cleft associated with a unilateral cleft and a proboscis-like structure is rarer still. We present a case managed at our center in which a 5-year-old male had a median cleft of the upper lip with an associated 'proboscis' and a microform unilateral cleft lip.
