The ScatterType CAPTCHA, designed to resist character– segmentation attacks and shown to be highly legible to human readers, is analyzed for vulnerabilities and is offered for e...
Trace effects are statically generated program abstractions, that can be model checked for verification of assertions in a temporal program logic. In this paper we develop a type a...
We give a uniform type-systematic account of a number of optimizations and the underlying analyses for a bytecode-like stack-based low-level language, including analysis soundness...
Abstract. This paper extends the logical approach to computable analysis via Σ–definability to higher type continuous data such as functionals and operators. We employ definab...
Abstract. We convert, via a version that uses constraints, a type inference system for strictness analysis into an algorithm which given an expression finds the set of possible typ...
