Incremental Flow Analysis

چکیده
interpretation is a technique for ow analysis widely used in the area of logic programming. Until now it has been used only for the global compilation of Prolog programs. But the programming language Prolog enables the programmer to change the program during run time using the built-in predicates assert and retract. To support the generation of eecient code for programs using these dynamic database predicates we extended abstract interpretation to be executed incrementally. The aim of incremental abstract interpretation is to gather program information with minimal reinterpretation at a program change. In this paper we describe the implementation of incremental abstract interpretation and the integration in our VAM 1P based Prolog compiler. Preliminary results show that incremental global compilation can achieve the same optimization quality as global compilation with little additional cost.

Comparative Evaluation of microleakage of Bulk-fill and Posterior Composite Resins Using the Incremental Technique and a Liner in Cl II Restorations
Background and Aim: In recent years there has been a surge in the use of tooth-colored restorations. However, the polymerization shrinkage of these materials can form gaps, resulting in microleakage. This study aimed to compare microleakage by using different materials and techniques. Materials and Methods: In this experimental study, Cl II cavities were prepared on the mesial surfaces of 60 s...

متن کاملSome Geometrical Bases for Incremental-Iterative Methods (RESEARCH NOTE)
Finding the equilibrium path by non-linear structural analysis is one of the most important subjects in structural engineering. In this way, Incremental-Iterative methods are extremely used. This paper introduces several factors in incremental steps. In addition, it suggests some control criteria for the iterative part of the non-linear analysis. These techniques are based on the geometric of e...
متن کاملApproximate Incremental Dynamic Analysis Using Reduction of Ground Motion Records
Incremental dynamic analysis (IDA) requires the analysis of the non-linear response history of a structure for an ensemble of ground motions, each scaled to multiple levels of intensity and selected to cover the entire range of structural response. Recognizing that IDA of practical structures is computationally demanding, an approximate procedure based on the reduction of the number of ground m...
متن کاملPerformance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملSeismic Design of Steel Structures Based on Ductility and Incremental Nonlinear Dynamic Analysis
In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...
