\Those who cannot remember the past, are condemned to repeat it." (Philosopher George Santayana) In this paper we show that keeping track of history enables signi cant improvements in the communication complexity of dynamic networks protocols. We improve the communication complexity for solving any graph problem from (E) to (V ), thus achieving the lower bound. Moreover, O(V ) is also our amort...

Maintenance has gained in importance as a support function for ensuring equipment availability, quality products, on-time deliveries, and plant safety. Cost-effectiveness and accuracy are two basic criteria for good maintenance. Reducing maintenance cost can increase enterprise profit, while accurate maintenance action can sustain continuous and reliable operation of equipment. As instrumentati...

Individual learning is central to the success of the transition phase in software maintenance offshoring projects. However, little is known on how learning activities, such as on-the-job training and formal presentations, are effectively combined during the transition phase. In this study, we present and test propositions derived from cognitive load theory. The results of a multiple-case study ...

Two information decay methods are examined that help multi-agent systems cope with dynamic environments. The agents in this simulation have human-like memory and a mechanism to moderate their communications: they forget internally stored via temporal decay, distributed by filtering it as passes through communication network. play foraging game, which performance depends on communicating facts r...

The success of distributed and semantic-enabled systems relies on the use of up-to-date ontologies and mappings between them. However, the size, quantity and dynamics of existing ontologies demand a huge maintenance effort pushing towards the development of automatic tools supporting this laborious task. This article proposes a novel method, investigating different types of similarity measures,...
