f or several decades, the selection of a proper tax base has been among the most serious concerns for the economic policy makers. the computable general equilibrium models analysis provides a comprehensive framework for the investigation of the effects of the adopted policies on the economy of a country. in the present study, using a static computable general equilibrium, the effects of tax re...

• Randomly generate an input which would follow the general expected input data template. For example, the JPEG format defines a number of data segments, which all start by byte 0xFF followed by the segment type identifier byte. The generator would independently generate all the fields and construct a globally valid JPEG file by taking into account the above specification. This approach require...

The purpose of this paper is to present four basic methods for compositional separate modular static analysis of programs by abstract interpretation: – simplification-based separate analysis; – worst-case separate analysis; – separate analysis with (user-provided) interfaces; – symbolic relational separate analysis; as well as a fifth category which is essentially obtained by composition of the...

source-code security analysis with static analysis tools. Since ITS4's release in early 2000 (www.cigital.com/its4/), the idea of detecting security problems through source code has come of age. ITS4 is extremely simple—the tool basically scans through a file looking for syntactic matches based on several simple " rules " that might indicate possible security vulnera-bilities (for example, use ...

Abstract. In static analysis, the semantics of the program is expressed as a set of equations. The equations are solved iteratively over some abstract domain. If the abstract domain is distributive and satisfies the ascending-chain condition, an iterative technique yields the most precise solution for the equations. However, if the above properties are not satisfied, the solution obtained is ty...

Title of dissertation: STATIC ANALYSIS IN PRACTICE Nathaniel Ayewah, Doctor of Philosophy, 2010 Dissertation directed by: Professor William Pugh Department of Computer Science Static analysis tools search software looking for defects that may cause an application to deviate from its intended behavior. These include defects that compute incorrect values, cause runtime exceptions or crashes, expo...

Parametric static analysis allows choosing a parameter value tobalance the precision and cost of the instantiated analysis. Wepropose an efficient approach to either find a cheapest parame-ter value to prove a given query or show that no such parame-ter value exists. Our approach is based on refinement, as in CE-GAR (counterexample-guided abstraction refinement), but applies...
