Wanted: Scalable Tracers for Diffusion

Wanted: Scalable Tracers for Diffusion Measurements

Scalable tracers are potentially a useful tool to examine diffusion mechanisms and to predict diffusion coefficients, particularly for hindered diffusion in complex, heterogeneous, or crowded systems. Scalable tracers are defined as a series of tracers varying in size but with the same shape, structure, surface chemistry, deformability, and diffusion mechanism. Both chemical homology and consta...

Adaptive and Scalable Congestion Control wanted!

Today’s Internet is mainly optimized for high goodput. This is not sufficient anymore, because more and more applications and thus a growing fraction of the Internet traffic require low latency. One aspect would be minimizing network queuing delay. This task should be performed by the network layer e.g. by configuring small buffers. Such a simple approach could be sufficient, if the transport l...

Wanted: Programmers for Handheld Devices

T he pace of change in computer technology can be breathtaking. Frequently, this makes it difficult for programmers to maintain skills that are in demand. Nowhere is this more apparent than in one of the newest and most dynamic segments of the computer industry: hand-held devices and wireless technology. The use of handheld devices is growing rapidly, as is the demand for applications that run ...

Wanted: Systems Abstractions for SDN

This paper presents a case for applying the principles of Software-Defined Networking (SDN) to middleboxes and end hosts. The challenges of configuring networking on network hosts resemble those addressed by SDN – numerous multi-vendor components, each with its own syntax and idiosyncratic corner cases, must be orchestrated smoothly. We have developed a prototype called NativeClick, a novel use...
