The longstanding problem of Brownian transport in a heterogeneous quasi one-dimensional medium with space-dependent self-diffusion coefficient is addressed in the overdamped (zero mass) limit. A satisfactory mesoscopic description is obtained in the Langevin equation formalism by introducing an appropriate drift term, which depends on the system macroscopic observables, namely the diffuser conc...

Remote Procedure Calls (RPC) are an established mechanism for coordinating activity between multiple processors in a distributed system. Their efficient use in Interprocess Communication (IPC) is difficult because underlying network protocols can have a great effect on system performance, especially when the IPC is within the same processor. This problem is compounded if the distributed system ...

The design of effective Medium Access Control protocol for ad hoc network is a highly challenging task due to the characteristics of such networks. The medium is shared and unreliable by definition, thus the access mechanism should be robust to channel errors and collisions. Furthermore, all the coordination functions must be totally distributed in a pure ad hoc environment. In this paper we ad...

In this article we propose the perspective of relationship as a conceptual approach to discipline sound design. Based on literature reviews and case studies, state that making design means designing relationships, even before sounds, include expression in current definitions discipline. Moreover, observe practices can be inscribed more than one relational perspective, thus widening scope possib...

in this study, nonlocal nonlinear instability and the vibration of a double carbon nanotube (cnt) system have been investigated. the visco-pasternak model is used to simulate the elastic medium between nanotubes, on which the effect of the spring, shear and damping of the elastic medium is considered. both of the cnts convey a viscose fluid and a uniform longitudinal magnetic field is applied t...

Background: Extensive full-thickness burns require replacement of both epidermis and dermis. In designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. Methods: In the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

A General Retrospective Olaf Zimmermann: How did your book come to be? How did you get together, and how did you nd your contributors and reviewers? Bobby Woolf: Martin Fowler was the matchmaker. When he wrote Patterns of Enterprise Application Architecture,2 Kyle Brown pointed out that his pattern language was not addressing asynchronous messaging. Martin felt that he already had plenty of pat...
