We have been engaged in research towards designing a software system called LOZ for learning the object oriented formal specification notation Object-Z. Initially, we conducted a survey to analyse the effectiveness of traditional methodologies for learning Z notation. In LOZ, the semiformal model UML is used in the intermediate phase between informal textual description and formal Object-Z desc...

In A.Z. v. B.Z. (2000), the Supreme Judicial Court of Massachusetts in Boston, Massachusetts, affirmed a lower court?s decision, ruling that contracts that require a party to become a parent against his or her will are unenforceable and contrary to public policy. The case centered around A.Z. and B.Z., a divorced couple who had previously used in vitro [4] fertilization [5] (IVF) to start a fam...

‎In this paper we characterize Bergman spaces with‎ ‎respect to double integral of the functions $|f(z)‎ ‎-f(w)|/|z-w|$,‎ ‎$|f(z)‎ -‎f(w)|/rho(z,w)$ and $|f(z)‎ ‎-f(w)|/beta(z,w)$,‎ ‎where $rho$ and $beta$ are the pseudo-hyperbolic and hyperbolic metrics‎. ‎We prove some necessary and sufficient conditions that implies a function to be...
