The control objective of exoskeleton for human performance augmentation is to minimize the human machine interaction force while carrying external loads and following human motion. This paper addresses the dynamics and the interaction force control of a 1-DOF hydraulically actuated joint exoskeleton. A spring with unknown stiffness is used to model the humanmachine interface. A cascade force co...

The expected value of information (EVI) is the most powerful measure of sensitivity to uncer­ tainty in a decision model: it measures the potential of information to improve the decision, and hence measures the expected value of the outcome. Stan­ dard methods for computing EVI use discrete vari­ ables and are computationally intractable for models that contain more than a few variables. Monte ...

The primary purpose of this paper is to highlight issues that are crucial when costing climatic impacts, particularly when the possibility is allowed for non-linearities, surprises, and irreversible events. The assumptions made when carrying out such exercises largely explain why different authors obtain different policy conclusions. Uncertainties become more significant when projections of cli...

Effect of biased noise fluctuations on the degree of squeezing as well as the intensity of a radiation generated by a one-photon coherent beat laser is presented. It turns out that the radiation exhibits squeezing inside and outside the cavity under certain conditions. The degree of squeezing is enhanced by the biased noise input significantly in both regions. Despite the presence of the biased...

ion hierarchy acceptability hierarchy Precondition propositions are partitioned into abstraction levels. Within a given abstraction level only a subset of the subgoals are considered. All precondition propositions are considered at each iteration. For a given subgoal, the set of potential establishers is independent of the current abstraction level. Elementary consequences are partitioned into ...

The development of new methods and rep­ resentations for temporal decision-making requires a principled basis for characterizing and measuring the flexibility of decision strategies in the face of uncertainty. Our goal in this paper is to provide a framework not a theory for observing how decision policies behave in the face of informational perturbations, to gain clues as to how they might beh...

Pitfalls in the collection, transport, processing, and interpretation of the expectorated sputum culture are discussed. Data are presented which suggest that, under stricdy controlled conditions, the culture of sputum may be a valuable adjunct to the diagnosis of bacterial pneumonia. In 1971 there were 2,068,000 diagnosed cases of bacterial pneumonia resulting in 34,183,000 days of disabled act...

The deontic logic DUS is a Deontic update semantics for prescriptive obligations based on the update semantics of Veltman. In ous the definition of logical validity of obligations is not based on static truth values but on dynamic action transitions. In this paper prescriptive defeasible obligations are formalized in update semantics and the diagnostic problem of defeasible deon­ tic logic is d...
