Gent Model

In this paper, nonlinear resonance characteristics of a dielectric elastomer actuator are investigated with special consideration on the thermal effects. A finite thermo-elasticity model based on the Gent model is constructed to analyze the vibrational response of the system. The equation of motion is derived via the Euler–Lagrange method. The multiple scales method and the Taylor series expansion are used to solve the governing equation. Nonlinear resonant responses of the system such softening/hardening and jump are explored. Furthermore, the influences of different system parameters including temperature, limiting stretch, damping, mechanical load, relative permittivity and voltage on the frequency response curves are explored. The results are compared with those obtained in the isothermal state, and those solved by numerical methods. It is found that both softening and hardening-type nonlinearities occur in the system in both non-thermal and thermal conditions.

Dynamical Parameters

In this manuscript we report new effects of resonance detuning on various dynamical parameters of a generic 3-wave system. Namely, for suitably chosen values of detuning the variation range of amplitudes can be significantly wider than for exact resonance. Moreover, the range of energy variation is not symmetric with respect to the sign of the detuning. Finally, the period of the energy oscillation exhibits non-monotonic dependency on the magnitude of detuning. These results have important theoretical implications where nonlinear resonance analysis is involved, such as geophysics, plasma physics, fluid dynamics. Numerous practical applications are envisageable e.g. in energy harvesting systems.

ABSTRAKPenelitian ini berjudul “The Media Conspiracy Behind the Death of Diana, Princessof Wales: A Study of Critical Discourse Analysis”. Penelitian ini bertujuan untuk menjelaskanbagaimana kematian Putri Diana direpresentasikan oleh The Daily Mail dalam artikelartikelpemberitaannya melalui dimensi tekstual dan juga memaparkan cara pandang TheDaily Mail sebagai pelaku media konspirasi pada praktik kerjanya terkait berita kematianPutri Diana dalam dimensi sosiokultural. Objek penelitian ini adalah The Daily Mail, salahsatu tabloid harian terbesar di Inggris. Metode yang digunakan dalam penelitian ini adalahmetode kualitatif, analisis deskriptif. Penulis menggunakan teori analisis wacana kritisFairclough (1995), disertai dengan beberapa teori pendukung lainnya, seperti teori klausasebagai representasi Halliday (2004), teori konspirasi Feaster (2008), Birchall (2006),Barkun (2003), Hodapp dan von Kannun (2008). Hasil dari penelitian ini menunjukkanbahwa representasi kematian Putri Diana dalam dimensi tekstual didapat melalui prosesmaterial, proses mental, proses relasional, proses verbal, dan proses eksistensial yangterdapat dalam artikel-artikel The Daily Mail. Sementara itu, cara pandang The Daily Mailsebagai pelaku media konspirasi atas berita kematian Putri Diana didapat melalui prosestataran sosial, tataran institusional, tataran sosial pada dimensi praktik sosiokultural.Kata Kunci: Transitivitas, Analisis Wacana Kritis, Media konspirasi.ABSTRACTThis thesis is entitled “The Media Conspiracy Behind the Death of Diana, Princessof Wales: A Study of Critical Discourse Analysis”. This thesis is aimed to describe therepresentation of Princess Diana’s death and The Daily Mail’s perspective as a mediaconspiracy actor through textual and sociocultural dimension. The object of this thesis isThe Daily Mail, one of the widest national daily newspapers in England. The method that isused in this thesis is a qualitative method, a descriptive analytic method. The writer uses thecritical discourse analysis theory of Fairclough (1995) and some other supported theories,such as clause as representation theory by Halliday (2004), the conspiracy theory by Feaster(2008), Birchall (2006), Barkun (2003), Hodapp and von Kannun (2008). The result of thisresearch shows that the representation in textual dimension that appear on Princess Diana’sdeath is derived from material process, mental process, relational process, verbal process, andexistential process. While The Daily Mail’s perspective on Princess Diana’s death is derivedfrom situational level, institutional level and social level of sociocultural practice dimension.Keywords: Transitivity, Critical Discourse Analysis, Media Conspiracy.
