The pitch control of electronic equipment is the overall and key problem system. traditional mainly depends on volume table, but this method too much hardware design, corresponding effect relatively unstable, cost high. Based research software, project improves collaborative filtering algorithm reduces range nearest neighbour set samples by introducing clustering algorithm, to further shorten s...

Extreme climatic events are growing more severe and frequent, calling into question how prepared our infrastructure is to deal with these changes. Current infrastructure design is primarily based on precipitation Intensity-Duration-Frequency (IDF) curves with the so-called stationary assumption, meaning extremes will not vary significantly over time. However, climate change is expected to alter...

Wireless mesh networking is an exciting new technology that has applications in defence, metro-area Internet access, and transient networks (e.g: disaster recovery, conventions). In this paper, we describe the design and implementation of a self-configuring, secure infrastructure mesh network architecture, called MeshCluster, composed using multi-radio network nodes. A subset of radio interface...

This paper presents a three-level taxonomical framework to systematize the research aspects and approaches of engineering design. As contextual categories of engineering design research the authors identify: (i) human assets, (ii) design knowledge, (iii) design philosophy, (iv) design theory, (v) design methodology, (vi) design technology, (vii) realm of artifacts, (viii) realm of processes, an...

This paper employs a heuristic evaluation checklist based on socio-cultural theory to assess open learning opportunities in the Visible Web where further integration of Infrastructure 2.0 or WEB 2.0 tools, accompanied by purposeful design (i.e. design which clearly ties integration and use of tools to achievement of specific learning outcomes), could improve the quality of interaction and ultim...
