In this paper, we present a geometric method for describing the effects of the delay induced uncertainty on the stability of a standard Smith Predictor control scheme. The method consists of deriving the stability crossing curves in the parameter space defined by the nominal delay, and delay uncertainty, respectively. More precisely, we start by computing the crossing set, which consists of all...

Smith was a pioneer epidemiologist, bacteriologist, and pathologist who made many contributions to medical science that were of far-reaching importance. He is best known for his work on Texas cattle fever, in which he and his colleagues discovered the protozoan agent and its means of transmission by ticks. This was the ¿ rst time that an arthropod had been de¿ nitively linked with the transmiss...

ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...

In an open-ended contingent valuation (CV) survey, a respondent can state any non-negative valuation for a given good. As the set of possible responses is infinite, the GibbardSatterthwaite theorem implies that such a survey cannot be incentive-compatible. That is, participants in an open-ended CV survey have an incentive to increase their utility by misrepresenting their preferences. This natu...
