Describe a DES with a property that satisfies

Diagram and formalize a PDA for the language L = {xiyj | j > i∧j −i ≡ 1 (mod 2)}.

Determine which constructs of RDFS and OWL can be expressed using monotonic rules. For example, the subclass relation is represented as c(X)→c0(X) (c0 is a subclass of c0).

Provide a succinct explanation of what the implication of memberwise assignment is.

Use the Pumping Lemma to show that the the following language over {a,b,c}* is not CF  {wct | t ∈ {a,b}* ∧ w is a substring of t}

Consider the following BNF:< parm-list > < parm-list > , < parm-list >| ID| NUMa. Show that this BNF is ambiguous using the sentence: ID, NUM, ID

Consider an equivalence relation R on X={a,b,c}. R= {(a,a), (a,c), (b,b), (c,a), (c,c) } [a]=

Quantifiers are called quantifiers because they express somethingabout the number of elements that satisfy a certain property. Showhow to express the following ‘quantified’ statements in predicatelogic with a unary relation symbol R. You don’t have to introduceany new quantifiers to do this, although you will need to keep inmind that the atomic formula x=yis always considered to be partof the language.(a) Exactly one x satisfies R(x).(b) At least one x satisfies R(x). (c) No more than three x satisfy R(x).(d) All but one x satisfy R(x).

Give an unambiguous regular grammar for the regular expression: a(b∗d(c|a)∗)∗.
