In this paper, a nonlinear control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear control strategy is developed that stabilizes a given nonlinear system by stabilizing a collection of nonlinear controlled...

To translate national childhood immunization guidelines to a computer-based reminder recall system, hierarchical system architecture design and combined approach of tabular and procedural knowledge representation are taken. Nested branches with hierarchical combinations of single antecedent variables are used to avoid logical incompleteness, redundancy and inconsistency. Mapping to the local el...

An innovative hierarchical microcell/macrocell architecture is presented. By applying the concept of cluster planning, the proposed sectoring arrangement can provide good shielding between microcells and macrocells. As a result, underlaid microcells can reuse the same frequencies as overlaying macrocells without decreasing the macrocell system capacity. With the proposed method, microcells not ...

This paper evaluates an architecture that implements a hierarchical routing structure for FPGAs, called a hierarchical FPGA (HFPGA). A set of new tools has been used to place and route several circuits on this architecture, with the goal of comparing the cost of HFPGAs to conventional symmetrical FPGAs. The results show that HFF'GAs can implement circuits with fewer routing switches, and fewer ...

To bridge the gap between advanced scheduling research and industrial practice, high performance scheduling needs to be combined with reactivity to disturbances. This paper presents an architecture for shop floor control (SFC) that builds upon the concepts of holonic manufacturing and combines the advantages of traditional hierarchical control with the benefits of distributed control. The archi...

This paper presents an algorithm-based low-power VLSI architecture for video object (VO) motion tracking. The new architecture uses a novel hierarchical adaptive structured mesh topology. The structured mesh offers a significant reduction in the number of bits that describe the mesh topology. The motion of the mesh nodes represents the deformation of the VO. The motion compensation is performed...

In this short paper, we propose a new key management architecture for Multicast communications. This architecture combines the complementary variable approach with hashed keys and hierarchical binary trees. This will reduce the number of transmissions at the joins/leaves of participants. Also, we explain a naming method, which allows to facilitate the understanding of the hierarchical binary tr...

One approach for automating industrial processes is a Distributed Control System (DCS) based on a hierarchical architecture. In this hierarchy, each level is characterized by a group of different tasks to be carried out within the control system and by using and generating different information. In this article, a reference model for the development of Intelligent Distributed Control Systems ba...

EEective management of battleeeld networks requires a hierarchical network management architecture wherein managers can dyanmically delegate management tasks to intermediate managers. In this paper we describe a novel paradigm called the spread-sheet paradigm which extends the traditional at SNMP management model to a hierarchical architecture. We present a spreadsheet MIB, language, and event ...

We have recently proposed a tool set that will aid the design of a dynamically reconfigurable processor through the use of a set of analysis and design tools. As part of the tool set, in this paper we propose a heterogeneous hierarchical routing architecture. Compared to hierarchical and symmetrical FPGA approaches building blocks are of variable size. This results in heterogeneity between grou...
