This paper presents the architecture of a multi-user distributed Virtual Environment (VE) software system currently used in the Virtual Perception Laboratory at the SRI International. It shows how the Linda parallel language helped in the realization of that system. An unusual interface used to fly through this shared VE is also presented: a handheld display (HHD).

duced allows to inspect software systems on architecture level described in ROOM notation. Explicit usage of domain knowledge in the development of concepts, methods, and tools guarantees suitability and user acceptance. The analysis of multi-language software systems is possible due to the realization of a seamlessly integrated yet open, modular, extensible, and flexible reengineering system.

We consider a stochastic flow driven by a finite-dimensional Brownian motion. We show that almost every realization of such a flow exhibits strong statistical properties such as the exponential convergence of an initial measure to the equilibrium state and the central limit theorem. The proof uses new estimates of the mixing rates of the multi-point motion.

This paper presents comparative analysis of various current differencing buffer amplifiers as an active building block in realization of analog signal processing circuit. The versatility of multi terminal active element (CDBA) as current mode and voltage mode circuit implementation using various methodologies has been reviewed. Also a comparative analysis based on characteristic parameters of v...

We consider the nonstandard constrained KP (ncKP) hierarchy which is obtained from the multi-constraint KP hierarchy by gauge transformation. The second Hamiltonian structure of the ncKP hierarchy can be simplified by factorizing the Lax operator into multiplication form, thus the generalized Miura transformation is obtained. We also discuss the free field realization of the associated W-algebra.

The paper considers a realization of a software application, which performs identification of duplicated records in a database, containing customer information. Some of the most important works in this direction are overviewed. The selected algorithm is discussed. The problems and appropriate solutions due to handling of multi-language information are listed. The developed application, built us...

Abstract – A voltage-mode (VM), multi-input single-output (MISO) type multifunction biquad is proposed. It uses only one operational transresistance amplifier (OTRA) as the active element, while previously reported VM multifunction filters require more OTRAs. Proposed MISO type biquad configuration can realize all five different filter transfer functions. Theoretical results are verified with P...

Selective, template-assisted growth of electrodeposited, layered materials leads to the top-down designable realization of nanopatterned surfaces with a large surface area (>1 cm(2)) comprised of multi-dimensional, multiscale (10 nm-1 μm) features, without the need of standard nanolithography. This process opens a manufacturable route to functional nanodevices that rely on anisotropic, nanoscal...

Recently, multi-robot systems are emerging in various industries. The multi-robot systems have several advantages in comparison with a single-robot system. The task of single-robot system is limited, because a bigger robot is required to perform more multiple functions. However, multi-robot systems can distribute the functions to each robot. The localization problem is essential for realization...

There is a pressing need to integrate large carnivore species into multi-use landscapes outside protected areas. However, an unclear understanding of coexistence hinders the realization of this goal. Here, we provide a comprehensive conceptualization of coexistence in which mutual adaptations by both large carnivores and humans have a central role.
