PPT-Predicate Logic

Goal of Logic T he goal of logic is to develop formal tests for validity This is done by finding deductively valid argument forms In SL we have two tests to determine valid argument forms the truthtable test and derivations Any argument that has a form that is valid according to the truthtable test is valid and any argument that has a form that can be proven is valid. Allow for fractions partial data imprecise data Fuzzify the data you have How red is this 1 RGB value 150255 What Is a Fuzzy Controller What Is a Fuzzy Controller Simply put it is fuzzy code designed to control something usually mechanical They ca Predicate Logic. 1 Aug 2013. Predicate Logic (§1.3). Predicate logic. is an extension of propositional logic that permits concisely reasoning about whole . classes. of entities.. Propositional logic (recall) treats simple . Closure properties in modal logic. Closure properties in modal logic. Specific modal logics. Specific . modal logics are . specified . by giving . formula schemes. , which are then called axioms, and . Chapter 1, Part II: Predicate Logic. With Question/Answer Animations. Summary. Predicate Logic (First-Order Logic (FOL), Predicate Calculus). The Language of Quantifiers. Logical Equivalences. Nested Quantifiers. Subject. The subject tells whom or what the sentence is about. . Example: . Lois Lenski. wrote Strawberry Girl. . The tooth with a point . is called a canine. . To find the subject, ask yourself who or what is doing something or about whom or what something is being said. . The limitation of propositional logic.  . Is not a proposition. Because we . can . not tell whether it is true or false unless . we . know . the value . of. .  .  . Predicate Logic. We denote the statement . We already know that the language of the machine is . binary. – that is, sequences of 1’s and 0’s. But why is this? . At the hardware level, computers are streams of signals. These signals only have two states of interest, high voltage and low voltage. . Logic Gates. NOT (Inverter) Gate. AND Gate. OR Gate. NAND Gate. NOR Gate. XOR Gate. Digital Signals. Digital signals 0 (false) or 1 (true). Digital signal 1 is represented by a small voltage.. Digital signal 0 is represented by no voltage.. Learn what a logic gate is and what they are for.. Be able to identify common logic gates.. Understand how truth tables work.. What is a logic gate?. Logic gates are part of the circuits inside your computer. They can take several INPUTS. . Jeremy Johnson. Presentation uses material . from. Huth. and Ryan, Logic . in Computer Science: Modelling and Reasoning about . Systems,. . 2nd Edition . Outline. Motivation (program specification & derivation). USING PREDICATE LOGIC Nature cares nothing for logic, our human logic: she has her own, which we do not recognize and acknowledge until we are crushed under its wheel. -Ivan Turgenev (1818-1883), Russian novelist and playwright Logic Gates.
