Cyber Physical Systems (CPS) combine digital computational systems with surrounding physical processes. Computations are meant to control and monitor the physical environment, which in turn affects the computations. The intrinsic heterogeneity of CPS demands the integration of diverse models to cover the different aspects of systems. The UML proposes a great variety of models and is very common...

Physical modeling of the phonatory and vocal tract systems has served as a useful tool to study many aspects of speech production. This paper offers a brief review of two specific types of physically-based models. One for simulating the vibration of the vocal folds and another for representing the vocal tract shape in the form of an area function. While much of the technical detail of these mod...

Cyber-physical systems, with their focus on creating closed-loop systems, have transformed a wide range of areas (e.g., flight systems, industrial plants, robotics, etc.). However, even after a century of health research we still W. Nilsen ( ) National Science Foundation, Arlington, VA, USA e-mail: [email protected] E.

Computer media develop progressively day by day. In the process of designing architecture, the employment of digital model seems to become more significant while the traditional physical model have still been used. However, the physical model had some unique characteristics which digital one has not. And those characteristics were what we intended to discover and put into the digital modeling e...

The paper discusses the possibility of constructing economic models using the methodology of model construction in classical mechanics. At the same time, unlike the “econophysical” approach, the properties of economic models are derived without involvement of any equivalent physical properties, but with account of the types of symmetry existing in the economic system. It has been shown that at ...

This paper focuses on the challenges of modeling cyber-physical systems that arise from the intrinsic heterogeneity, concurrency, and sensitivity to timing of such systems. It uses a portion of an aircraft vehicle management systems (VMS), specifically the fuel management subsystem, to illustrate the challenges, and then discusses technologies that at least partially address the challenges. Spe...

Recent progress in three di€erent areas involving the modeling of the physical properties of composites is reviewed. These include: (i) theoretical approaches to microstructure/property relations; (ii) X-ray microtomography, an imaging technique that enables one to obtain high-resolution three-dimensional microstructural phase information of a composite sample in a non-intrusive manner; and (ii...

Model-based tools have the potential to significantly improve the process of developing novel cyber-physical systems (CPS). In this paper, we consider the question of what language features are needed to model such systems. We use a small, experimental hybrid systems modeling language to show how a number of basic and pervasive aspects of cyber-physical systems can be modeled concisely using th...

Senspectra is a computationally augmented physical modeling toolkit designed for sensing and visualization of structural strain. The system functions as a distributed sensor network consisting of nodes, embedded with computational capabilities and a full spectrum LED, which communicate to neighbor nodes to determine a network topology through a system of flexible joints. Each joint, while servi...

A physical model was utilized to show that the neural system can memorize a target position and is able to cause motor and sensory events that move the arm to a target with more accuracy. However, this cannot indicate in which coordinates the necessary computations are carried out. Turning off the lights causes the error to increase which is accomplished by cutting off one feedback path. The ge...
