Scholars usually agree that small and medium-sized enterprises (SMEs) active in construction are not very innovative when compared with large-size construction enterprises. This is particularly evident in the case of adoption and diffusion of innovation associated with information and...

This paper assesses the use of information and communication technologies (ICTs) and their impact on the economic performance of small- and medium-scale enterprises (SMEs) of three East African countries: Kenya, Tanzania and Uganda. Findings of the paper suggest that the diffusion of ICT among...

As a representative of a complex technological system, the so-called wireless multihop ad hoc communication networks are discussed. They represent an infrastructure-less generalization of todays wireless cellular phone networks. Lacking a central control authority, the ad hoc nodes have to...

Due to their inherent complexity, engineered wireless multihop ad hoc communication networks represent a technological challenge. Having no mastering infrastructure the nodes have to selforganize themselves in such a way that for example network connectivity, good data traffic performance and...

The paper aims to examine the prospects for closer economic relations among China, Japan and Korea. Using the Grubel-Lyold Index, this paper reviews the industrial structural change and its related trade patterns in terms of intra-regional, intra-industry trade and the comparative advantages...

Wireless multi-hop ad hoc communication networks represent an infrastructure-less and self-organized generalization of todays wireless cellular networks. Connectivity within such a network is an important issue. Continuum percolation and technology-driven mutations thereof allow to address this...
