While listeners’ emotional response to music is the subject of numerous studies, less attention is payed to the dynamic emotion variations due to the interaction between artists and audiences in live improvised music performances. By opening a direct communication channel from audience members to performers, the Mood Conductor system provides an experimental framework to study this phenomenon. ...

In an effort to expand the traditional focus on film texts within studies, case studies New Film History have increasingly drawn attention structures and processes that determine as medium social institution. Building this, Cinema (NCH) focuses more radically cinema a cultural institution its importance in everyday life. The central claim of this article is move away from authors has obscured t...

The ability of educational applications to adapt to individual students has been a sought-after feature for more than a decade. The difficulty of developing this kind of software and the lack of adequate tools that facilitate this endeavor have hindered the participation of instructors and teachers in the elaboration of adaptive applications. In this paper we describe an authoring tool, ATLAS, ...

This paper evaluates the performance of three popular technologies used to interconnect machines on clusters: Fast Ethernet, Myrinet and Giganet. To achieve this purpose, we used the NAS Parallel Benchmarks. Surprisingly, for the LU application, the performance of Fast Ethernet was better than Myrinet. We also evaluate the performance gains provided by VIA, a user lever communication protocol, ...

In this text, we intend to explore the possibilities of sound manipulation in a context of augmented reality (AR) through the use of robots. We use the random behaviour of robots in a limited space for the real-time modulation of two sound characteristics: amplitude and frequency. We add the possibility of interaction with these robots, providing the user the opportunity to manipulate the physi...

The New World was ravaged by smallpox for several centuries after the Spanish conquest. Jenner’s discovery of the smallpox vaccine made possible the prevention and control of smallpox epidemics. In response to a large outbreak of smallpox in the Spanish colonies, King Charles IV appointed Francisco Xavier de Balmis to lead an expedition that would introduce Jenner’s vaccine to these colonies. D...

Knowing the detailed topology of the Internet at the Autonomous System (AS) level is extremely valuable for both researchers and industry when making network policies. Although there are many measurement projects and databases that provide this information, such as ARK, RETRO, ONO and PeeringDB, they only offer a partial view for analyzing end-to-end Internet routing paths and they do not focus...

Exposure to genetic and biochemical experiments typically occurs late in one's academic career. By the time students have the opportunity to select specialized courses in these areas, many have already developed negative attitudes toward the sciences. Given little or no direct experience with the fields of genetics and biochemistry, it is likely that many young people rule these out as potentia...

A variety of HCI toolkits help designers and developers author particular styles of interactive systems. However, the design, use and evaluation of toolkits are fraught with many challenges. This paper focuses on a subset of challenges that arise from the fit between the toolkit and its intended audience. These challenges include the skill set of that audience, the resources they have, and how ...
