Method: The stress distribution was analyzed i...

Many public goods that are provided by coalitions have a group-size e¤ect. Namely, people prefer to consume a public good in a larger coalition. This paper studies local public goods games with anonymous and separable group-size e¤ect. The core is nonempty when coalition feasible sets are monotonic and players’preferences over public goods satisfy a condition called cardinal connectedness. More...

Initialising and managing security parameters for personal mobile devices within a Personal Area Network (PAN) presents a variety of security problems. In this paper we consider one possible paradigm for mobile device security management, namely the use of a ‘personal CA’ to provide certificates within a PAN. The security requirements for such a personal CA are analysed, and a novel protocol fo...
