An Abstract Reachability Approach by Combining HOL Induction and Multiway Decision Graphs

引用

Journal of Computer Science & Technology 2009年第1期24卷 76-95页

作者： sa'ed Abed Otmane Ait moha.ed Ghiath Al-sammane ECE Department Concordia UniversityMontrealCanada

In this paper, we provide a necessary infrastructure to define an abstract state exploration in the HOL theorem prover. Our infrastructure is based on a deep embedding of the Multiway Decision Graphs （MDGs） theory in HOL. MDGs generalize Reduced Ordered Binary Decision Diagrams （ROBDDs） to represent and manipulate a subset of first-order logic formulae. The MDGs embedding is based on the logical formulation of an MDG as Directed Formulae （DF）. Then, the MDGs operations are defined and the correctness proof of each operation is provided. The MDG teachability algorithm is then defined as a conversion that uses our MDG theory within HOL. Finally, a set of experimentations over benchmark circuits has been conducted to ensure the applicability and to measure the performance of our approach.

NuMDG:A New Tool for Multiway Decision Graphs Construction

引用

Journal of Computer Science & Technology 2011年第1期26卷 139-152页

作者： sa'ed Abed Yassine Mokhtari Otmane Ait-moha.ed Sofiene Tahar Department of Computer Engineering Hashemite UniversityZarqaJordan Department of Electrical and Computer Engineering Concordia UniversityMontrealCanada

Multiway Decision Graphs （MDGs） are a canonical representation of a subset of many-sorted first-order logic. This subset generalizes the logic of equality with abstract types and uninterpreted function symbols. The distinction between abstract and concrete sorts mirrors the hardware distinction between data path and control. Here we consider ways to improve MDGs construction. Efficiency is achieved through the use of the Generalized-If-Then-Else （GITE） commonly operator in Binary Decision Diagram packages. Consequently, we review the main algorithms used for MDGs verification techniques. In particular, Relational Product and Pruning by Subsumption are algorithms defined uniformly through this single CITE operator which will lead to a more efficient implementation. Moreover, we provide their correctness proof. This work can be viewed as a way to accommodate the ROBBD algorithms to the realm of abstract sorts and uninterpreted functions. The new tool, called NuMDG, accepts an extended SMV language, supporting abstract data sorts. Finally, we present experimental results demonstrating the efficiency of the NuMDG tool and evaluating its performance using a set of benchmarks from the SMV package.

BACKGROUND Irritable bowel syndrome(IBS) is a common functional gastrointestinal disorder. Dysregulation of the gut–brain axis plays a central role in the pathophysiology of IBS. It is increasingly clear that the microbiome plays a key role in the development and normal functioning of the gut–brain *** To facilitate the identification of specific areas of focus that may be of relevance to future research. This study represents a bibliometric analysis of the literature pertaining to the microbiome in IBS to understand the development of this *** The data used in our bibliometric analysis were retrieved from the Scopus database. The terms related to IBS and microbiome were searched in titles or abstracts within the period of 2000–2019. VOSviewer software was used for data *** A total of 13055 documents related to IBS were retrieved at the global level. There were 1872 scientific publications focused on the microbiome in IBS. There was a strong positive correlation between publication productivity related to IBS in all fields and productivity related to the microbiome in IBS(r = 0.951, P ed States was the most prolific country with 449(24%) publications, followed by the United Kingdom(n = 176, 9.4%), China(n = 154, 8.2%), and Italy(n = 151, 8.1%). The h-index for all retrieved publications related to the microbiome in IBS was 138. The hot topics were stratified into four clusters:(1) The gut–brain axis related to IBS;(2) Clinical trials related to IBS and the microbiome;(3) Drugmediated manipulation of the gut microbiome;and(4) The role of the altered composition of intestinal microbiota in IBS *** This is the first study to evaluate and quantify global research productivity pertaining to the microbiome in IBS. The number of publications regarding the gut microbiota in IBS has continuously grown since 2013. This finding suggests that the future outlook for interventions targeting the gut microbiota in

IT is well known that there exists unfrozen film water in frozen soils due to the action of sur-face energy among soil particles and frost heave occurs by water migration under the tempera-ture gradient. The problem is how to determine the amount of frost heave quantitatively. The amount of frost heave induced by ice segregation can be calculated by the following e-quations:
