We present a new method for partial order planning in the STRIPS/SNLP style. Our contribution centers on how we drop the closed world assumption while adding a useful class of universally quantiied propositions to the representation of states and actions. These quan-tiied expressions allow expression of partially closed worlds , such as \block A has no other block on it", or \F is the only Tex ...

Sensor measurements are typically vitiated by a measurement error caused by the sensor’s imperfectness or external disturbances. Whenever this measurement error is to large to be neglected it is necessary to fuse measurements from multiple sensors into a more dependable estimation of the measurement value. This paper derives a fusion method for fusing tuples of sensor measurements and confidenc...

We have proposed an extension of Ecological Interface Design (EID) to encompass the design of auditory displays. Our analysis shows that EID can succeed in this task if all stages of Cognitive Work Analysis (CWA) are employed and if an extra “attentional mapping” stage is added, which maps the attentional need of the human operators. A review of auditory perception and attention suggests that t...

This paper presents a method for fusing measurement samples from multiple sensors into a dependable robust estimation of a variable in the control environment. Each sensor measurement is represented by a measurement value and a confidence marker that corresponds to the respective variance of the measurement. We propose the Confidence-weighted Averaging (CWA) algorithm for fusing measurements wi...

Coastal water quality affects millions of people in the United States every year from residents of coastal communities to beach visitors. The Environmental Protection Agency (EPA) has set forth standards for surface waters nationwide to reduce the amount of pollution released into them. In order to enforce these standards, methods for monitoring bacterial concentrations in coastal waters have b...

I. Foreword Our studies are directed at determining the adsorption mechanisms and reaction pathways for the chemical warfare agent simulant (CWA) for GB (Sarin) on metal oxide surfaces and nanoparticles. By learning about how surface structure, nanoparticle size, composition, and surface co-adsorbates affect the overall interfacial chemistry, we are providing insight that can be applied toward ...

BACKGROUND Health care is a complex sociotechnical system. Patient treatment is evolving and needs to incorporate the use of technology and new patient-centered treatment paradigms. Cognitive work analysis (CWA) is an effective framework for understanding complex systems, and work domain analysis (WDA) is useful for understanding complex ecologies. Although previous applications of CWA have des...
