Ocean Acoustic Waveguide Remote Sensing: Visualizing Life Around Seamounts
No full textCollectively, seamounts form a significant biome the size of
Europe with important but heavily depleted fisheries (see
Box 12 on page 206 of this issue [Etnoyer et al., 2010]). Recently,
large seamount tracts have been put aside as protected areas
(see Pitcher et al., 2010). Yet, we remain largely ignorant of the
dynamics of fish and other nektonic organism movements around
seamounts. Hence, there is a pressing need for a survey tool to
effectively monitor how stocks respond to management closures,
and to determine which fisheries might actually be sustainable
Dimensional response analysis of bilinear systems subjected to non-pulselike earthquake ground motions
No full textThe maximum inelastic response of bilinear single-degree-of-freedom systems when subjected to ground motions without distinguishable pulses is revisited with dimensional analysis by identifying time scales and length scales in the time histories of recorded ground motions. The characteristic length scale is used to normalize the peak inelastic displacement of the bilinear system.
The paper adopts the mean period of the Fourier transform of the ground motion as an appropriate time scale and examines two different length scales which result from the peak ground acceleration and the peak ground velocity. When the normalized peak inelastic displacement is presented as a function of the normalized strength and normalized yield displacement, the response becomes self similar and a clear pattern emerges.
Accordingly, the paper proposes two alternative predictive master curves for the response which involve solely the strength and yield displacement of the bilinear SDOF system in association with either the peak ground acceleration or the peak ground velocity, together with the mean period of the Fourier transform of the ground motion. The regression coefficients that control the shape of the predictive master curves are based on 484 ground motions recorded at rock and stiff soil sites and are applicable to bilinear SDOF systems with post-yield stiffness ratio equal to 2% and inherent viscous damping ratio equal to 5%

Dimensional response analysis of multistorey regular steel MRF subjected to pulselike earthquake ground motions
No full textAn alternative and efficient procedure to estimate the maximum inelastic roof displacement and the maximum inelastic interstorey drift ratio along the height of regular multi-storey steel MRF subjected to pulse-like ground motions is proposed. The method and the normalized response quantities emerge from formal dimensional analysis which makes use of the distinct time scale and length scale that characterize the most energetic component of the ground shaking. Such time and length scales emerge naturally from the distinguishable pulses which dominate a wide class of strong earthquake records and can be formally extracted with validated mathematical models published in literature. The proposed method is liberated from the maximum displacement of the elastic single-degree-of-freedom structure since the self similar master curve which results from dimensional analysis involves solely the shear strength and yield roof displacement of the inelastic multi-degree-of-freedom system in association with the duration and acceleration amplitude of the dominant pulse. The estimated inelastic response quantities are in superior agreement with the results from nonlinear time history analysis than any inelastic response estimation published previously
A DIFFERENTIATED DIDACTIC APPROACH TO TEACHING THE ARTS (D.D.A.T.A.) FOR THE PURPOSES OF SPECIAL EDUCATION AND TRAINING
No full textThe goal of the present work is to present the key of pedagogical and didactical principles involved in the differentiated teaching of such arts as music and dance for the purposes of Special Education and Training (Makris, 2019). The paper also will link that differentiated approach with Positive Psychology and, more specifically, with the P.E.R.M.A. model developed by Positive Psychology founder M. Seligman (Slavin, Schindler et a.l., 2012); and with M. Apter’s Reversal Theory (Makris, 2009).At this presentation, we will be presenting didactical principles, methodological tools and case studies deriving from our clinical work that we carried out for 7 years (2012-2019) with mentally challenged individuals (Makris, 2019). In this study also we will have the chance to focus in teamwork teaching so that we may comprehend the principles of that approach experientially. What is more, this work will also focus on potential fields offering themselves for future academic research.
