Application of Bayesian Networks in risk diagnostics arising from the degree of urban regeneration area degradation
PublicationUrban regeneration as a complex project, generates many extremely specific threats affecting the increase of investment risk. Its unique nature causes that probability parameter, normally applied in the process of risk quantification, is extremely difficult to estimate. Due to lack of historical data urban regeneration related activities are therefore associated with uncertainty. According to the authors, a useful tool for resolving...

Planning Around Polarisation: Components of Finding Common Ground Based on Regeneration Projects in London and Gdańsk
PublicationVarious forms of public participation in urban design and planning—as presented and discussed in literature—have recently been challenged by the needs and expectations of different stakeholders, including those coming from the private sector. This comes with a redefinition of the public good and the roles and responsibilities of municipal authorities in post‐liberal times. As a result, contemporary participatory processes need...

Next generation automatic IP configuration deployment issues
PublicationAlthough Dynamic Host Configuration Protocol for IPv6 (DHCPv6) protocol was defined in 2003, it was designed as a framework rather than a complete solution to the automatic configuration in IPv6 networks. There are still some unsolved problems and new options yet to be defined. One example of such case is Fully Qualified Domain Name (FQDN) option, which final version has been published in late 2007. It describes DHCPv6 client...
