Wide-band test instrumentation often needs signal routing. This is accomplished with mechanical switches, which are expensive and slow. When isolation requirements are not high, it is also done with electronic switches. Some high isolation switches available in the market are very expensive. Mini-Circuits has developed a pair of low-cost, high isolation, fast switching, TTL-driven, connectorize...

The META-EVI is a novel interface created from an extensive augmentation of the Steiner MIDI EVI, a brass style ‘electric valve instrument’ (EVI), which was expanded with 11 analog sensors and 10 digital switches. The main goal of this project consists in achieving a performance tool that exhibits truly innovative levels of musical expression much beyond what is possible with the original instr...

In this paper we propose a new mental representation of how markets, technology and their interaction concur in explaining the why of a certain innovation instead of another. We empirically test this theory in the telecommunication switches industry. We consider innovation as a new alignment of needs and opportunities, where markets and technology are not the sources, but the actors in this ali...

Providing Qualities of Service (QoS) is a desirable feature for most network routers and switches. The capability to service differential classes is a prerequisite to enable QoS. It has been shown that Output Queued (OQ) switches implementing Weighted Fair Queuing (WFQ) can provide QoS. However, OQ switches have high speed requirements for the fabric switch and the memory bandwidth, which makes...

Optical switching cores are fast gaining importance for deployment in internet switches/routers. The reconfiguration of these switches requires a large timely switching overhead. The design of efficient algorithms that take into account the configuration overhead has been widely researched. However, all previous research solely focuses on switching algorithms that optimize the performance featu...

Library-based and pre-compiled visualization tools incur many penalties that hinder the adoption of visualization as a technique for many fields. Libraries necessitate familiarity with the data structures and control flows that are incumbent in traditional programming, but not central to visualization. Task-specific visualization applications alleviate these needs, but induce users to move data...

Software developers make various decisions when implementing software. For instance, they decide on how to implement an algorithm most efficiently or in which way to process user input. When code is revisited during maintenance, the underlying decisions need to be understood and possibly adjusted to the current situation. Common documentation approaches like JavaDoc neither cover knowledge rela...
