This paper investigates stochastic resonance in parallel arrays of uncoupled saturating devices. The Fisher information is used to demonstrate the possibility of noise improved parameter estimation for arbitrary parametric signals. Especially, it is shown that improvement by noise always occurs in these arrays, for any configuration of the input signal, even in optimal configuration. The result...

A heterogeneous cluster can incur the performance degradation caused by the load unbalance in executing the application for homogeneous cluster. The total execution time can be sometimes improved by neglecting some of the PEs because communication time is reduced. This study examines to invoke multiple processes on fast processing elements (PEs) to avoid load unbalance. In this study, the execu...

Multiple computers and/or processors offer interactive music systems more processing power, more inputs and outputs, and more tolerance to failure. Systems based on multiple computers require careful design paying particular attention to communication and configuration. The virtual patchbay is a new structure in Aura that simplifies the configuration and interconnection of objects in a distribu...

Enterprise capable database products have evolved into incredibly complex systems, some of which present hundreds of configuration parameters to the system administrator. So, while the processing and storage costs for maintaining large volumes of data have plummeted, the human costs associated with maintaining the data have continued to rise. In this presentation, we discuss the framework and a...

This paper addresses the issues of scheduling and allocation/configuration of a point-topoint parallel system, for safety-critical hard real-time systems. Three specific topics are considered: an analysable computational model that has sufficient expressive power whilst retaining flexibility for allocation; a scheduling approach that allows the worst case response times for each system’s transa...

Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...

Dependency injection frameworks such as the Spring framework rely on dynamic language features of Java. Errors arising from the improper usage of these features bypass the compile-time checks of the Java compiler. This paper discusses the application of static code analysis as a means to restore compile-time checking for Spring-related configuration errors. First, possible errors in the configu...

The proposed methodology has been implemented in modular system architecture to avoid deadlock situations in real time using a rule base approach. A system configuration consisting of work centers, buffers, robots, and loading/unloading stations is taken with limited capacities as the example case study. A part mix with a variety of processing sequences such as, re-entrant only, jig-jag, re-ent...

In this paper, the design of the overall architecture and the development of specific components of a supervised, automatic system for guidance of an ROV are described. Basically, automation is achieved by inserting a PC, equipped with A/D-D/A boards, in the operator/ROV loop. In this way, the original configuration of the ROV manual guidance system is substituted by a more versatile, user-frie...

To achieve extreme electromagnetic enhancement, we propose a plasmonic Tamm states (PTSs) configuration based on the metal-insulator-metal Bragg reflector, which is realized by periodically modulating the width of the insulator. Both the thick (2D) and thin (3D) structures are discussed. Through optimization performed by the impedance-based transfer matrix method and the finite difference time ...
