The Joint Precision Approach and Landing System (JPALS) is being developed as a single replacement for the navigation, precision approach and landing systems currently used by military aircraft. Shipboard Relative GPS (SRGPS) is a JPALS variant being developed to support flight operation in the shipboard environment. Because of the stringent SRGPS performance requirements, differential carrier ...

This paper develops an approach to minimize the number of process tooling adjustments and deliver an acceptable fraction of non-conforming products based on given product quality specification limits in assembly processes. A linear model is developed to describe the relationships between product quality and process tooling locating positions. Based on the model, the process mean shifts of tooli...

This paper presents simpler alternative formulae and procedures of implementation to deal with the relative range statistic (moments, distribution and quantiles) used in the construction of range control charts for process dispersion monitoring. The Tippett’s integral formulae for sample relative range moments and distribution are revisited and simpler new alternative expressions are proposed t...

Alarms in the ICU sound frequently and 85-99% of cases do not require clinical intervention. As alarm frequency increases, clinicians develop ‘alarm fatigue’ resulting in desensitization, missed alarms, and delayed responses. This is dangerous for the patient when an alarm-provoking event requires clinical intervention but is inadvertently missed. Alarm fatigue can also cause clinicians to: set...

background : few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. the purpose of this study was to determine threshold levels of meningitis outbreak in hamadan province, west of iran . methods : data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 march 2010 to 20 march 2012 were use...

In practice, automated monitoring of spacecraft relies heavily on limit-sensing and simulation. Unfortunately , limit-sensing tends to be too imprecise (missing alarms) and simulation tends to be too precise (false alarms). To help overcome those disadvantages, we present an anytime algorithm called envelope learning and monitoring via error relaxation (ELMER). It can incrementally generate suc...
