Non linear site response simulation during the 1999 Chi-Chi earthquake in Taiwan
No full texthttp://www.iitk.ac.in/nicee/wcee/article/13_1923.pdfInternational audienceThis paper presents an application of the non-linear multi-kinematics dynamic model implemented in CyberQuake software (Modaressi [1]), analysing the seismic response at a site located within the Chang- Hwa Coastal Industrial Park during the 1999 Chi-Chi earthquake in Taiwan. Computed NS, EW and UP ground accelerations obtained with this model under undrained and two-phase assumptions, are in good agreement with the corresponding accelerations recorded at seismic station TCU117, either for peak location, amplitudes or frequency content. During simulation, liquefaction occurs between depths 1.3m and 11.3m, which corresponds to the observed range attested by in place penetration tests and liquefaction analyses
Calendar conversion for real-time systems
No full textIn some applications of real-time systems such as monitoring and control, calendar referencing plays a significant role. The system needs the precise year, month, day, hour, minute and second in order to function correctly. Generally, real-time systems are based on computers whose operating systems use the Gregorian calendar. The official calendar of some countries, however, is not based on the Gregorian calendar. To reduce the human errors and make the system friendlier, it is necessary to present the date in the local format. In this paper, the optimum method of time-keeping for a distributed real-time system is described and then a solar calendar called Khayyami is reviewed and a novel algorithm for conversion between Gregorian and Khayyami calendars is presented. Khayyami is the official calendar of Iran and Afghanistan and is used in surrounding areas such as the Central Asian countries and Kurdish area. The methods described in this paper were implemented in a monitoring and control system and the practical results justify these
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
