The operation of the photovoltaic (PV) system under partial shading conditions (PSC) is complicated since output characteristic PV profoundly affected by heterogeneous irradiance PSC. This paper proposes a dynamic reconfiguration framework to tackle PSC in array. Continuous array cloud-induced considered developing an emulator moving cloud. In addition, Particle Swarm Optimization and Rao algor...

Nowadays, a large number of practical systems in aerospace and industrial environments are best represented as hybrid systems that consist of discrete modes of behavior, each defined by a set of continuous dynamics. These hybrid dynamics make the on-line fault diagnosis task very challenging. In this work, we present a new modeling and diagnosis framework for hybrid systems. Models are composed...

Recently, distributed generation technologies have received much attention for the potential energy savings and reliability assurances that might be achieved as a result of their widespread adoption. Fueling the attention have been the possibilities of international agreements to reduce greenhouse gas emissions, electricity sector restructuring, high power reliability requirements for certain a...

Dynamic materials have been widely studied for regulation of cell adhesion that is important to a variety of biological and biomedical applications. These materials can undergo changes mainly through one of the two mechanisms: ligand release in response to chemical, physical, or biological stimuli, and ligand burial in response to mechanical stretching or the change of electrical potential. Thi...

Computing nodes in a flexible network arrangement must support a range of programming facilities. Modern controllers allow already programs stored in different degrees of permanency. Other measures are more focused on structural changes. The overall potential is to-day not supported by a single device. It is the purpose of this paper to outline the architectural requirements for a generic LOFAR...

Runtime Reconfiguration (RTR) allows reconfigurable architectures to adjust to application phased behavior at runtime. In this paper, we examine the performance of one such RTR system and the impact of system parameters such as reconfigurable array size and reconfiguration time. To gauge the effectiveness of our RTR algorithm, we compare its performance against an equivalent system that relies ...

In a linear array of processors, a single faulty element in any location is sufficient to stop the flow of information from one side to the other. A common approach for achieving fault tolerance in such systems is through the incorporation of redundant links in a regular fashion. These links (called bypass links) can be activated in a reconfiguration phase to bypass faulty elements. There are s...

On-chip Built-In Self-Test (BIST) based diagnosis of the embedded Field Programmable Gate Array (FPGA) core in a generic System-on-Chip (SoC) is presented. In this approach, the embedded processor core in the SoC is used for reconfiguration of the FPGA core for BIST, initiating the BIST sequence, retrieving the BIST results, and for performing diagnosis of faulty programmable logic blocks, memo...

In this paper we present a novel RAM-based field programmable mixedsignal integrated device consisting of a Field Programmable Gate Array (FPGA), a set of programmable and interconnectable analog cells, and a microprocessor core. This processor can run general purpose user programs, handle the dynamic reconfiguration of the programmable blocks and probe in real time internal digital and analog ...

Advanced mechatronic systems have to integrate existing technologies from mechanical, electrical and software engineering. They must be able to adapt their structure and behavior at runtime by reconfiguration to react flexibly to changes in the environment. Therefore, a tight integration of structural and behavioral models of the different domains is required. This integration results in comple...
