The performance features of MEMS transducers allow the development of a new class of small, low-power sensor microsystems which utilize a suite of sensors to support a wide range of applications. This paper presents a system-level framework for constructing such microsystems where system modularity for application adaptability is a primary design consideration. System architecture, communicatio...

In this paper we address the problem of defining social roles in MAS. Social roles provide the basic structure of social institutions and organizations. We start from the properties attributed to roles both in the MAS and the Object Oriented community, and we use them in an ontological analysis of the notion of social role. We thus identify as the main properties of social roles being definitio...

In this paper we present the initial conceptual design of an authoring tool for the emergent narrative agent architecture FAtiMA that powers the virtual bullying drama FearNot!. We explain that the process of authoring emergent narrative to a large part consists of designing a planning domain for a virtual character planner and explain the difficulties this task poses to the non-technical autho...

Two studies investigated the role of locomotor experience on visual proprioception in 8-month-old infants. Visual proprioception refers to the sense of self-motion induced in a static person by patterns of optic flow. A moving room apparatus permitted displacement of an entire enclosure (except for the floor) or the side walls and ceiling. In Study 1, creeping infants and prelocomotor/walker in...

Very high concentrations of nitrogen dioxide (NO2) have been measured in arenas using combustion engine-powered resurfacing machines. This study was performed to compare the occurrence of asthma in children playing ice hockey in arenas using propane-powered machines and in children attending arenas using electric machines. Children regularly playing hockey in the arenas (nine propane, six elect...

OBJECTIVES The aim of this study was to clarify the effect of the play between the bracket and the archwire on anterior tooth movement subjected to the retraction force from various lengths of power arms in sliding mechanics. MATERIALS AND METHODS A three-dimensional finite element method was used to simulate en masse anterior tooth retraction in sliding mechanics. The displacements of the ma...

Abstract

Ships play the major role in bulk transportation and they need their special energy system. This paper proposes a stochastic programing method for optimal sizing of a hybrid ship power system with energy storage system (ESS), photovoltaic power (PV) and diesel generator. To account for uncertainties, in this study a two-stage stochastic mixed-integer non-linear programing is used to model the o...

Integration of distributed generations (DGs) in power grids is expected to play an essential role in the infrastructure and market of electrical power systems. Microgrids are small energy systems, capable of balancing captive supply and requesting resources to retain stable service within a specific boundary. Microgrids can operate in grid-connected or islanding modes. Effective islanding detec...
