In missile guidance system, to reduce the interception “miss distance,” it is important to choose a suitable guidance law and navigation constant. This paper investigates and compares the system behavior of guidance laws under different navigation constants. Based on use of the adjoint technique, miss distance sensitivity analyses which consider the system noise, target step maneuver, initial h...

In some cases, an initial behavior is followed by a similar behavior. In other cases, an initial behavior is followed by an opposing behavior. We posit that a passive guidance system can nonconsciously guide behavior when there is goal conflic...

OBJECTIVE Although the placement of esophageal self-expandable stents (SES) can effectively relieve dysphagia after radiotherapy in patients with esophageal cancer (EC), it may induce severe esophageal complications. This article reports a case of emergency endotracheal intubation in an EC patient who suddenly developed severe dyspnea two months after SES placement. METHODS Electronic broncho...

this paper describes the development of a fuzzy decision support system (fdss) for the assessment of risk in e-commerce (ec) development. a web-based prototype fdss is suggested to assist ec project managers in identifying potential ec risk factors and the corresponding project risks. a risk analysis model for ec development using a fuzzy set approach is proposed and incorporated into the fdss....

One of the original goals of intelligent educational systems was to guide each student to the most appropriate educational content. In previous studies, we explored both knowledge-based and social guidance approaches and learned that each has a weak side. In the present work, we have explored the idea of combining social guidance with more traditional knowledge-based guidance systems in hopes o...
