An audio transformer is used in a guitar amplifier to match the impedances of the power amplifier and a loudspeaker. It is important to understand the influence of the audio transformer on the overall sound quality for realistic tube amplifier emulation. This paper proposes to simulate the audio transformer using a wave digital filter model, which is based on the gyrator-capacitor analogy. The ...

Soper’s pain-brain theory, based on evolutionary biology, represents a provocative breakthrough for both suicidology and positive psychology. The main thesis of the book is that evolved way choosing to live rather than die in face unbearable suffering develop zest happiness meaning. His new theory can be summed up by two-by-two matrix “pain-type” versus “brain-type” reducing pain, “keeper” “fen...

The market for digital modeling guitar amplifiers requires that the digital models behave like the physical prototypes. A component of the iconic Fender Bassman guitar amplifier, the tone stack circuit, filters the sound of the electric guitar in a unique and complex way. The controls are not orthogonal, resulting in complicated filter coefficient trajectories as the controls are varied. Becaus...

Berthing force is a critical dynamic lateral force in the design of berthing structures, having equal relevance when compared to seismic forces. Besides, the construction cost of berthing structures is very high which can be optimized by calculating precise design berthing energy on fender and selecting optimum fender system. In the present study, design berthing energy of bulk carriers having ...

In this paper, the variants of fender protection traditional port tugs and possibility using on unmanned vessels such type are considered; main elements investigated. At present, technical level mechanisms, instruments software allows creating crewless vessels. One promising directions in development is tugs, since having relatively large river sea they perform production tasks water area appro...

The equilibrium of the market for offenses is studied by means of a multi-agent based simulation. The results show more detailed properties of the market’s equilibrium compared to the theoretical results derived by Fender [5]. Some preliminary results are described.
