This work studies the dynamic strain localization and constitutive relationship of a Ti3Al2.5V alloy in jet engine containment system transparent polycarbonate conceived for aircraft canopy application by Digital Image Correlation (DIC) technique from quasi-static condition to high rates at different temperatures. The responses two materials show significant rate temperature sensitivities. Obse...

This paper is a transcription of the texts read by three commentators appointed scientific committee to open first debate session convened in June 2020 as continuation virtual QSN conference held month before. It should be noted that, for practical reasons well time constraints (there were researchers from countries with different zones), comments did not address presentations order which they ...

Abstract This paper investigates the influence of stress state on equivalent plastic fracture strain in 2024-T351 aluminum alloy. Eighteen unique states at failure—with triaxialities ranging from 0.388 (compressive) to −0.891 (tensile) and Lode parameters −0.978 1.000—are explored through mechanical experiments specimens with various geometries under multiple loading conditions. These include t...

We study containment of conjunctive queries that are evaluated over databases that may contain tuples with null values. We assume the semantics of SQL for single block queries with a SELECT DISTINCT clause. This problem (“null containment” for short) is different from containment over databases without null values and sometimes more dif-

AIM Distal tibial fractures with intra-articular involvement during childhood are injuries with potentially severe complications if not treated promptly. Daily clinical practice indicates that sole use of plain radiographs may lead to misdiagnosis and subsequent erroneous selection of suitable treatment. The role of computed tomography (CT) in the classification and treatment decision of these ...

Since 1977, cost containment has been an integral part of health policy in the Federal Republic of Germany. The common goal of the cost-containment acts was to bring the growth of health care expenditures in line with growth of wages and salaries of sickness fund members. The Health Care Reform Act of 1989 is the most recent manifestation of this policy. The main features of the numerous cost-c...

Our goal is to study type containment, some variations on the type-containment relation, and how it can be extended to other programming language features such as products, side effects, existential types. We will study some language meta-theoretical properties. Notre but est d’étudier le type containment, quelques variantes sur la relation de type containment, et comment elle peut être étendue...

Although containment is frequently advocated as a fall-back option for eradication, analysis shows that it is not necessarily more economic or effective. While containment has one major advantage over eradication, in that a smaller area is managed, this must be balanced against its disadvantage; that it must continue indefinitely. Moreover, both containment and eradication programs are at risk ...
