This paper presents a dynamically reconfigurable multivariable Micro-Electro-Mechanical Systems (MEMS) sensor array, capable of reconfiguration in real time, to meet the sensing demands of unattended systems operating in highly variable environments, with an emphasis on maintaining operation of these systems in the presence of structural damage. This array is comprised of multiple instances of identical sensors which can be dynamically reconfigured to target a variety of measurands including acceleration, rotational rate, magnetic fields, temperature, air pressure and density. A simulated environment is used to illustrate how the array can be dynamically reconfigured to respond to variations in several of these parameters. Also shown are simulations that demonstrate the ability of such a sensor array to continue operation in the presence of structural damage.

Information Description

Testing and verification of the interface between software components are particularly important due to the large number of complex interactions, which requires the traditional modeling languages to overcome the existing shortcomings in the aspects of temporal information description and software testing input controlling. This paper presents the real-time extended interface automata (RTEIA) which adds clearer and more detailed temporal information description by the application of time words. We also establish the input interface automaton for every input in order to solve the problems of input controlling and interface covering nimbly when applied in the software testing field. Detailed definitions of the RTEIA and the testing cases generation algorithm are provided in this paper. The feasibility and efficiency of this method have been verified in the testing of one real aircraft braking system.

Networked and virtual organizations (NVO’s) represent a new organizational paradigm, but no effective management solution exists. NVOs are supposed to be dynamically reconfigurable and more effective to manage than traditional organizations, even though the roles embedded within their structures disappear when a project is done. No matter how short-lived, a key opportunity afforded by an NVO is to extract its performance data for better control and also to measure its cultural and technological integration. To capture the essence of such a metric, we review traditional organizations. Whether a real or virtual organization, the central problem remains the lack of a theory of dynamic interdependence generated by social situations as when forming a dyad between two humans alters the cognitions and actions of both. Introduced to solve this central problem, the quantum mathematical model of dynamic social interdependence has recently gained credibility in the field and from a pilot study in the laboratory. Our ultimate aim is to develop a real-time metric to control and optimize NVO performance.
