The evolution of molecular quasispecies on two diierent complex tness landscapes, the Sherrington Kirkpatrick spin glass and the Graph Bipartitioning landscape, is investigated in dependence on replication delity and population size. Three diierent regimes of replication delity are detected. At high copying delity one obtains a population with high mean tness localized around a time independent...

in spite of pivotal position of effectiveness construct in organizational theory this concept has been appropriately developed yet and there is less consensus on the criteria for its definition in organization. the varieties of effectivenss models and approaches to its utilization are many. discussion on preferring one model of effectiveness to another is a continuous process. for instance advo...

National consensus standards reflect the opinions of professionals who work at all levels of the public and private sectors in technology development, manufacturing, training, financial analysis, personnel, academia as well as insight from the fi...

Simultaneous tracking and formation control is addressed for a team of autonomous agents that evolve dynamically in a space containing a measurable vector field. Each agent measures the local value of the field along its trajectory and occasionally shares relevant information with other agents, in order to estimate the spatial average obtained from averaging measurements across all agents. Usin...

The pervasive spread of smart objects is encouraging the development of smart environments, such as Smart Cities and Smart Homes. In the Internet of Things (IoT) vision, even the most common and simple object is expected to acquire information from the surrounding ambient and to cooperate with other objects to achieve a common goal, fulfilling the expected quality requirements. In such a hetero...

Coordination of different, independent processes is a very important aspect in the area of distributed systems. In order to coordinate each other, participants of a distributed system often have to agree on some common knowledge such as locking of a shared resource. The general problem how to reach agreement on some value is also known as consensus problem. In many practical systems, the consen...
