To reproduce a highly realistic sound field reproduction, we have developed a three dimensional sound reproduction system based on the boundary surface control principle. We set up an Internet connection among multiple systems, which enables distant speakers to carry out voice telecommunication by simultaneously hearing the same sound field and perceiving the other speakers' simulated positions...

Understanding of the development of the reproductive organs is essential to the evaluation of abnormalities in sexual differentiation. Recent advances resulting from application of genetic, biochemical, and ultrastructural techniques have helped to clarify the mechanisms regulating gonadal and reproductive tract development. The present review considers the major processes of sexual differentia...

Topic of this paper is an interactive sound reproduction system to create virtual sonic environments and visual spaces, called Virtual Audio Reproduction Engine for Spatial Environments (VARESE). Using VARESE, Edgard Varèse’s Poème électronique was recreated within a virtual Philips Pavilion. The system draws on binaural sound reproduction principles including spatialization techniques based on...

The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

In this paper, we outline a basic framework for the reproduction of the wave field of moving virtual sound sources. Conventional implementations usually reproduce moving virtual sources as a sequence of stationary positions. This process leads to various artifacts as reported in the literature. On the example of wave field synthesis, we show that the explicit consideration of the physical prope...

The QESTRAL project has developed an artificial listener that compares the perceived quality of a spatial audio reproduction to a reference reproduction. Test signals designed to identify distortions in both the foreground and background audio streams are created for both the reference and the impaired reproduction systems. Metrics are calculated from these test signals and are then combined us...

The evolution and maintenance of sexual reproduction may involve important tradeoffs because asexual reproduction can double an individual's contribution to the gene pool but reduces diversity. Moreover, in social insects the maintenance of genetic diversity among workers may be important for colony growth and survival. We identified a previously unknown termite breeding system in which both pa...
