Crafting the mind of prosocs agents
(2006)
PROSOCS agents are software agents that are built according to the KGP model of agency. KGP is used as a model for the mind of the agent, so that the agent can act autonomously using a collection of logic theories, providing ...
Impossibility results for weak threshold networks
(1997)
It is shown that a weak threshold network (in particular, threshold network) of width w and depth d cannot be constructed from balancers of width p0, p1, . . . , pm-1, if w does not divide Pd, where P is the least common ...
A personalization method based on human factors for improving usability of user authentication tasks
(2014)
Aiming to ensure safety of operation to application providers and improve the usability of human computer interactions during authentication, this paper proposes a two-step personalization approach of user authentication ...
Towards the personalization of CAPTCHA mechanisms based on individual differences in cognitive processing
(2013)
This paper studies the effect of individual differences on user performance related to text-recognition CAPTCHA challenges. In particular, a text-recognition CAPTCHA mechanism was deployed in a three-month user study to ...
Extended semantics and optimization algorithms for CP-networks
(2004)
Preference elicitation is a serious bottleneck in many decision support applications and agent specification tasks. Ceteris paribus (CP)-nets were designed to make the process of preference elicitation simpler and more ...
A combinatorial characterization of properties preserved by antitokens
(2000)
Balancing networks are highly distributed data structures used to solve multiprocessor synchronization problems. Typically, balancing networks are accessed by tokens, and the distribution of the tokens on the network’s ...
Threshold counters with increments and decrements
(2002)
A threshold counter is a shared data structure that assumes integer values. It provides two operations: Increment changes the current counter value from v to v+1, while Read returns the value [v/w], where v is the current ...
