Capturing emotions in voice: A comparative analysis of methodologies in psychology and digital signal processing

People use their voices to communicate not only verbally but also emotionally. This article presents theories and methodologies that concern emotional vocalizations at the intersection of psychology and digital signal processing. Specifically, it demonstrates the encoding (production) and decoding (recognition) of emotional sounds, including the review and comparison of strategies in database design, parameterization, and classification. Whereas psychology predominantly focuses on the subjective recognition of emotional vocalizations, digital signal processing relies on automated and thus more objective vocal affect measures. The article aims to compare these two approaches and suggest methods of combining them to achieve a more complex insight into the vocal communication of emotions.

Rapid Research and Design Parameterization of Outdoor Double Intelligent Cabinet

It is inevitable requirement of modern engineering rapid design for outdoor double intelligence cabinet.Taking VB as the tool,rapid parameter module of geometric parameters and boundary conditions of double intelligent cabinet was designed，the exhaust air of fan as adjustable object,then Fluent software for numerical simulation of temperature was called quickly ,using VB to display Fluent calculation results,the rapid parameter module can timely show the significant influence of exhaust air to the inside temperature.It has important guiding significance to practical engineering.

High Quality 3D Restoration of Photographed Structures Using V.R. Technologies

The paper describes methods for graphical reconstruction from a single image acquired with a completely uncalibrated camera or even from lithography. The proposed method involves a multimodal approach, such as: digital photogrammetry, 3D photo modelling, CAD design, parameterization, VRML programming. In addition, we propose a visualization method based on Virtual Reality technology, using an immersive CAVE like 3D system. The 3D reconstructed model offers the possibility of details visualization, quickly change the geometry, textures, environment, viewpoint and size and can also be easily accessed using Internet browsers and a VRML client plug-in. As an example and a practical application of the presented method, there was completed the virtual 3D reconstruction of the demolished church Sf. Vineri from Bucharest. The sources of virtual reconstruction were archival, architectural and contemporary historical information.
