Revisiting hierarchical quorum systems
Proceedings 21st International Conference on Distributed Computing Systems, 2002In distributed systems, it is often necessary to provide coordination among the multiple concurrent processes. Quorum systems provide a decentralized approach to provide such coordination that is resilient to node and communication link failures. Quorum systems are highly available and may be used to balance the load among the elements of the system ...

Constructing Hierarchical Set Systems
Annals of Combinatorics, 2005This paper introduces a new algorithm to achieve data clusters. The procedure works with dissimilarity data. It starts with the so-called Apresjan hierarchy and while the needed calculations are easy and fast, the resulting nested clusters give a very good understanding of the data.

On prefetching in hierarchical caching systems
IEEE International Conference on Communications, 2003. ICC '03., 2004Hierarchical caching is deployed to scale up the explosive Web growth, and the expiration-based mechanism is adopted as an economic means to support the weak consistency in this context. However, given a hierarchy, the user perceived performance heavily depends on its position.

Dynamics in Hierarchical CSCW Systems
2003Computer supported cooperative work (CSCW) is a popular research topic in recent years. In classical cooperative applications, cooperation cannot be adapted to the dynamics and hierarchies of real world. According to the formal specification of dynamic cooperation in hierarchical systems, a dynamic hierarchical cooperative system model, DHCSCW, is ...

Hierarchical specification of system behavior
Proceedings 1997 High-Assurance Engineering Workshop, 2002Complex systems are commonly broken up into a hierarchy of composed components. This methodology reduces the complexity of the system os a whole and allows teams of designers to attack the problem of definition. We present and propose a hierarchical methodology for the specification of the behaviors of complex designs. We introduce a single BY operator,

Hierarchical Structuration in Protocellular System
Small Methods, 2023AbstractSpatial control is one of the ubiquitous features in biological systems and the key to the functional complexity of living cells. The strategies to achieve such precise spatial control in protocellular systems are crucial to constructing complex artificial living systems with functional collective behavior.

1974
The purpose of this paper is to contribute to the mathematical treatment of hierarchies of decision-making systems as given e.g. by Mesarovic e.a. in [1]. This will be done by making explicit in the formalization of the relevant concepts a few aspects which in [1] were supposed to be implicitly understood, and had to be kept in mind to distinguish ...

Wastage in a Hierarchical Manpower System
Journal of the Operational Research Society, 1979A Markov chain model for the description, testing and comparison of wastage in hierarchical manpower systems is given in this paper. With regard to manpower planning, emphasis is placed on unnatural wastage (resignations, dismissals and transfers) in comparing systems. All forces of transition are state and service length specific.

Modeling Visibility in Hierarchical Systems
2006We consider hierarchical systems where nodes represent entities and edges represent binary relationships among them. An example is a hierarchical composition of Web services where the nodes denote services and edges represent the parent-child relationship of a service invoking another service.

Combining and Distributing Hierarchical Systems
1998It is possible with RAISE to specify and do most refinement in an applicative framework, and then transform the concrete applicative specification into an imperative sequential or concurrent one. This is a change from a style more appropriate to proof of refinement to a style more appropriate to implementation.
