abstract background: given the fact of irrecoverable consequences of noise in industrial societies and the environment, acoustic filter (silencer) is an instrument which obstacles the transmission of sound waves. a sort of this silencer is helmholtz resonator (branch amplifier) which comes to sound appropriate for low and below 200 hz frequencies in fan and channel noise. the purpose of this ar...

Lei Jin argues in her paper, "Silence and Sound in Kurosawa's Throne of Blood," that silence and sound are employed as vehicles to explore the major themes of Kurosawa's Throne of Blood, fate, ambition, and destruction. By examining closely a few dramatic moments of the film, Lei demonstrates that silence and the interaction between silence, natural sound, and Noh music enhance the effect of Ku...

This paper presents an argumentation-based approach to deliberation, the process by which two or more agents reach a consensus on a course of action. The kind of deliberation that we are interested in is a process that combines both the selection of an overall goal, the reduction of this goal into sub-goals, and the formation of a plan to achieve the overall goal. We develop a mechanism for doi...

The authors conducted a pilot test of the organizational culture model in a health care setting. The study was based on a questionnaire with mixed quantitative and qualitative analysis. Quantitative analysis confirmed the expected distribution of responses among the subcultures for all three questions, with significant differences in two of the three. Qualitative analysis further strengthened t...

Bioethicists appearing in the media have been accused of "shooting from the hip" (Rachels, 1991). The criticism is sometimes justified. We identify some reasons our interactions with the press can have bad results and suggest remedies. In particular we describe a target (fostering better public dialogue), obstacles to hitting the target (such as intrinsic and accidental defects in our knowledge...

Two concepts from narrative theory that often appears in discussions about game sound are diegetic and non-diegetic (Collins, 2007, 2008; Ekman 2005; Grimshaw 2008; Grimshaw & Schott 2007; Jørgensen 2007b, 2008; Stockburger, 2003; Whalen, 2004). The terms are used in film theory to separate elements that can be said to be part of the depicted fictional world from elements that the fictional cha...

In describing human performance in sound perception, in word recognition, in speech understanding, and in dialogue handling, we generally test human limits under controlled conditions and try to understand the underlying mechanisms, however, the human system itself has already been built by nature. In speech and language technology we would like to equal, or perhaps even outrank, human performa...
