Redundancy-constrained minimum-cost design of water distribution networks
Redundancy of looped water distribution networks is quantified with expected shortage, a reliability surrogate which can represent frequency, duration and severity of damages caused by failures of components. Based on this surrogate and its variations (total expected shortage and allowable shortage …

Integrity and access control in untrusted content distribution networks
A content distribution network (CDN) makes a publisher's content highly available to readers through replication on remote computers. Content stored on untrusted servers is susceptible to attack, but a reader should have confidence that content originated from the publisher and that the content is …
