The paper describes the development of a supervisory control scheme that adapts to the presence of degradation faults and minimises any resulting increase in energy consumption or deterioration in occupant comfort. Since there is a high degree of uncertainty associated with the results of any fault identi cation scheme in information-poor systems of this type, the supervisory control scheme use...

The first aim of this study was to determine the age group at which marathon performance declines in top male and female runners and to compare that to the runners of average ability. Another aim of this of this study was to examine the age-related yearly decline in marathon performance between age group winners and the average marathon finisher. Data from the New York (NYC), Boston, and Chicag...

In the fundamental production inventory model, in order to solve the economic production quantity (EPQ) we always fix both the demand quantity and the production quantity per day. But, in the real situation, both of them probably will have little disturbances every day. Therefore, we should fuzzify both of them to solve the economic production quantity (q*) per cycle. Using α-cut for defuzzific...

Flexible pavements are prone to premature deterioration, and researchers unresolved regarding the importance of underlying causes resulting in inappropriately selected modeling parameters increased uncertainty predicting subsequent behavior performance. A windshield survey, literature fuzzy Delphi study were undertaken as complementary approaches costly conventional investigations identify reas...

Several factors may contribute to the structural failure of cast and ductile iron water mains, the most important of which is considered to be corrosion. The ANSI/AWWA C105/A21.5–99 10-point scoring (10-P) method is commonly used to predict corrosivity potential of a given soil sample using certain soil properties. The 10-P and other scoring methods use binary logic to classify the soil either ...

In general, most complex systems, which are constructed by collecting more than one part to perform either single or multiple functions, are usually repaired rather than replaced after failures, since such systems can be restored to fully implement the required functions by methods other than replacing the entire system (Ascher & Feingold, 1984). However, the successive times between failures a...

This article argues that a significant shift is taking place in the sociological study of religion, and seeks to outline its main features. In order to do so it returns to Stephen Warner’s classic article of 1993 which drew a contrast between ‘old’ and ‘new’ paradigms in the sociology of religion. It develops Warner’s analysis by setting these paradigms in their European and American contexts r...

The Chilean government commissioned a quasi-experimental study with a pre-/postintervention design that had two general aims: (a) to assess infants' psychoaffective developmental levels (pre-intervention phase) and (b) to evaluate whether an intervention based on the promotion of socioemotional development modifies the infant's psychoaffective development. Sixty-two institutionalized infants an...

Pollinator decline has been linked to landscape change, through both habitat fragmentation and the loss of habitat suitable for the pollinators to live within. One method for exploring why landscape change should affect pollinator populations is to combine individual-level behavioural ecological techniques with larger-scale landscape ecology. A modelling framework is described that uses spatial...
