Desalting/dehydration plants (DDP) are often installed in crude oil production units in order to remove water-soluble salts from an oil stream. This paper describes the development of simple inferential estimators for product quality of the desalting/dehydration process. The inferential estimators were constructed to capture the relationship between the product quality of the plant and the proc...

In the present work a novel inferential control strategy cascaded with a nonlinear profile position controller is employed to control the top and bottom product compositions of a simulated depropanizer column. The inferential model for estimating product compositions is developed using the wave propagation model, and the composition profile position of both rectifying and stripping section is c...

Runeson, Juslin, and Olsson (2000) proposed (a) that perceptual learning entails a transition from an inferential to a direct-perceptual mode of apprehension, and (b) that relative confidence—the difference between estimated and actual performance—indicates whether apprehension is inferential or direct. In 3 experiments participants received feedback on judgments of force; the results replicate...

One sometimes believes that P without grasping that P. For example, a complete achromat might believe that ripe tomatoes are red without grasping this fact. My aim in this paper is to shed light on the difference between merely believing a fact or proposition and grasping it. I focus on two possible theories of grasping: the inferential theory, which explains grasping in terms of inferential ro...

Computerized lessons that reflect stimulus equivalence principles were used to teach college students concepts related to inferential statistics and hypothesis decision making. Lesson 1 taught participants concepts related to inferential statistics, and Lesson 2 taught them to base hypothesis decisions on a scientific hypothesis and the direction of an effect. Lesson 3 taught the conditional in...

An inferential feedforward control strategy is developed and applied to a simulated distillation column. In this control strategy, the effects of disturbances on the primary process variables (top and bottom compositions) are inferred from uncontrolled secondary process variables (tray temperatures) which can be easily measured. The proposed strategies are particularly useful when disturbances ...

Climate variability and change are risk factors for climate sensitive activities such as agriculture. Managing these risks requires “climate knowledge”, i.e. a sound understanding of causes and consequences of climate variability and knowledge of potential management options that are suitable in light of the climatic risks posed. Often such information about prognostic variables (e.g. yield, ra...
