This study compared various biased estimation and subset selection regression techniques over a wide range of realistic situations. In an attempt to make the results applicable to the class of all practical regression problems, the parameters relevant to a comparison of the techniques involved were varied systematically. An outline of the design follows. (1) The residual variance ((sigma)('2)) ...

Definitions of Petri Net . Part I Waldemar

In the sequel M is a Petri net. Let us consider X , Y . Let us assume that X misses Y . The functor PTempty f (X ,Y ) yielding a strict Petri net is defined by: (Def. 4)2 PTempty f (X ,Y ) = 〈X ,Y, / 0〉. Let us consider X . The functor Tempty f (X) yields a strict Petri net and is defined by: (Def. 5) Tempty f (X) = PTempty f (X , / 0). The functor Pempty f (X) yields a strict Petri net and is ...

Security Enhancement of Chang-Lee Anonymous E-Voting Scheme

In recent years, several electronic voting (e-voting) schemes for communication networks have been proposed. In 2006, Chang and Lee presented an anonymous electronic voting scheme which can be applied in real-world elections. However, this paper shows that ChangLee’s e-voting scheme suffers from susceptibility to security attacks. As a result, some essential security requirements of their e-vot...
