the seismic performance of hybrid braces composed of steel and shape memory alloy (sma) was investigated in this paper. six types of hybrid braces were used, constituted by sma content of 0, 20, 40, 60, 80, and 100%. a nonlinear dynamic analysis was performed under el centro earthquake records, with the maximum acceleration of 0.6g and 0.9g. our results showed that the seismic performance, i.e....

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

We present a music-robotic system capable of performing an accompaniment for a musician and reacting to human performance with gestural and facial expression in real time. This work can be seen as a marriage between social robotics and computer accompaniment systems in order to create more musical, interactive, and engaging performances between humans and machines. We also conduct subjective ev...

This work presents the creation of a dynamic energy model able to simulate, with a reasonable workload, a very large number of integrated building-plant systems with different scales and resolutions, in order to have a design support for architects and designers, reducing their modeling effort and errors. The model includes the dynamic simulation of the building envelope, all the heating plant ...

The need for time-critical analysis and understanding of the underlying group structure from transactional data has been growing in domains such as law enforcement and customs. Kubica et al. (2003) proposed k-groups, an algorithm based on probabilistic generative model for discovering underlying groups in data. Even though k-groups is reported to be signficantly faster than its predecessor GDA ...

The paper aims at (i) understanding expressiveness in gestures using computational modeling and (ii) exploit this understanding in artistic applications, where the enhancement of the expressiveness in interactive music/dance/video systems is a major goal. A multi-layered conceptual framework is presented and examples are given of its use in interactive art performances.

Understanding and following musical improvisations with a computer requires methods different from those needed when following score-based musical performances. This paper discusses questions related to interactive music systems for the recognition and accompaniment of tonal improvisations. This includes discussion about rhythmic parsing and harmonic analysis with a recursive Bayesian classifie...

This paper presents a quantitative reliability and availability evaluation method for subsea blowout preventer (BOP) system by translating fault tree (FT) into dynamic Bayesian networks (DBN) directly, taking account of imperfect repair. The FTs of series system and parallel system are translated into Bayesian networks, and extended to DBN subsequently. The multi-state degraded system is used t...

We report the results of an experiment in which human subjects were trained to perform a perceptual matching task. Subjects were asked to manipulate comparison objects until they matched target objects using the fewest manipulations possible. An unusual feature of the experimental task is that efficient performance requires an understanding of the hidden or latent causal structure governing the...
