‘<Emphasis Type="Italic">if p then q</Emphasis>’ . . . and all that: Logical Elements in Reasoning and Discourse

In this paper we explore differences in use of the so-called ‘logical’ elements of language such as quantifiers and conditionals, and use this to explain differences in performance in reasoning tasks across subject groups with different educational backgrounds. It is argued that quantified sentences are difficult natural bases for reasoning, and hence more prone to elicit variation in reasoning behaviour, because they are chiefly used with a pre-determined domain in everyday speech. By contrast, it is argued that conditional sentences form natural premises because of the function they serve in everyday speech. Implications of this for the role of logic in modelling human reasoning behaviour are briefly considered.     

Analytic Calculi for Logics of Ordinal Multiples of Standard t-Norms

For two propositional fuzzy logics, we present analytic proofcalculi, based on relational hypersequents. The logic consideredfirst, called M, is based on the finite ordinal sums of ukasiewiczt-norms. In addition to the usual connectives—the conjunction, the implication and the constant 0—we use a furtherunary connective interpreted by the function associating witheach truth value a the greatest -idempotent below a. M is aconservative extension of Basic Logic. The second logic, called M, is based on the finite ordinal sumsof the product t-norm on (0, 1]. Our connectives are in thiscase just the conjunction and the implication.     

Stiction – definition, modelling, detection and quantification

Stiction or high static friction is a common problem in spring-diaphragm type control valves, which are widely used in the process industry. Recently, there have been many attempts to understand, define, model and detect stiction in control valves. There are several methods for detecting stiction, but quantification of the actual amount of stiction still remains a challenge. This paper discusses briefly the definition and modelling of stiction. Then it demonstrates a new method to detect and quantify the actual amount of valve stiction using routine operating data. The proposed method is completely data-driven. No additional excitation or experimentation of the plant is required.

关于烟气在线监测装置SO2周期性异常的分析与处理

本文针对目前电厂脱硫烟气连续排放监测系统（CEMS）中SO2数据周期性波动,通过对历史数据曲线分析排查,发现取样探头温控仪故障导致取样探头加热器无法加热,烟气中水分遇冷凝结在管壁,管壁中的水分平时吸收烟气中的SO2,导致测量值偏低,待水珠汇聚变大流入下面带加热的取样管中后,水中溶解SO2的集中释放,导致数据在短期急剧上升,蒸发释放完后回归到原来的水平,形成这样一个周期性吸收和集中释放的过程。可见烟气取样管道温度保护环节在烟气测量中的作用非常重要。
