1. Introduction Many languages of the world use differences in voice quality or phonation type to contain linguistic functions. Thus, in certain languages, lexical items are differentiated solely on the basis of differences in voice quality. For example, in Jalapa Mazatec, an Otomanguean language spoken in Mexico (Kirk et al. 1993), the three words /ja! / meaning 'tree', /jaª ! / meaning 'he we...
This experiment consists of determining the modal properties of a model structure. Many buildings in the practical world can be reasonably approximated by shear structures in which only one translational degree of freedom is taken into account for each floor level. Due to the simple characteristics of a shear structure, it is possible to determine its modal properties, such as the natural frequ...
The issues surrounding the use of ambient vibration modes for the location of structural damage via dynamically measured flexibility are examined. Several methods for mass-normalizing the dynamic mode shapes extracted from ambient modal data are implemented and compared. The methods are applied to data from a series of ambient modal tests on an actual highway bridge. The results indicate that t...
A new methodology for automated extraction of repeated patterns in time-series data is presented, aimed in particular at the analysis of musical sequences. The basic principles consists in a search for closed patterns in a multi-dimensional parametric space. It is shown that this basic mechanism needs to be articulated with a periodic pattern discovery system, implying therefore a strict chrono...
To tackle the major problem of traditional TCP in wireless network, an end-to-end congestion control algorithm (TSBCC) is proposed based on time series. The algorithm creates time series consisting of the time interval of ACK, calculates the next ACK arrival time by the GARCH modal, analyzes the types of data packet loss, and sets congestion window size using different strategies according to d...
this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...
the nonlinear static procedures (nsps) proposed by design codes do not lead to reliable results especially for tall buildings. they generally provide inconsistent estimates of inelastic seismic demands, especially for the top floors due to their inabilities in considering the higher modes effects. in this paper, a new enhanced pushover procedure is proposed which is based on the envelope of the...
David Lewis is one of the most influential philosophers of our age, and On the Plurality of Worlds is his magnum opus. OPW offers an extended development and defense of the hypothesis that there are many universes, things of the same kind as the universe in which we all live, move, and have our being. Lewis calls these universes ―worlds‖, deliberately recalling the notion of a ―possible world‖ ...
for the first time in the history of logic, abd al razzaq al-jili (d. 570/1174), in the treatise al-lame fi al-shakl al-rabe, dealt with the modal syllogisms of the fourth figure. previous to him, dinha, the priest, and ibn salah al-hamadani had discussed the non-modal moods of the fourth figure. jili’s treatise deals only with simple modalities and ignores the complex ones. his pupil, fakhr al...
The presentation concerns a method for tracking cycle lengths in voiced speech and breaking up vocal cycle length fluctuations in cycle length jitter and cycle length tremor. The tracking of the cycle lengths is based on a dynamic programming algorithm, which does not request that the signal is locally periodic and that the average period length is known a priori. The cycle length time series a...
