Dependencies among the tasks performed by web services affect how the web services are composed. We propose an approach to managing dependencies among tasks in order to support web services composition. We define BT-DML, a markup language to express dependencies. We describe a prototype system called web services manager (WSM) that implements this language to support various tasks in web servic...

BACKGROUND Sexual minority women are more likely than heterosexual women to have ever experienced intimate partner violence (IPV). Although IPV is associated with sexual risk and poor reproductive health outcomes among US women overall, little is known about whether IPV is related to sexual and reproductive health indicators among sexual minority women in particular. METHODS Baseline data fro...

The GLOWA-initiative, funded by the German Ministry of Research and Education (BMBF), has been established to address the consequences of Global Change, which is understood as affecting future development far beyond Climate Change and to include changes in land use, population and development, on regional water resources. The GLOWA-Danube project (www.GLOWA-Danube.de) is dealing with the Upper ...

We study the role of time reversal symmetry (TRS) in circular photogalvanic (CPG) responses considering chiral Weyl semimetal (WSM) while a quantized CPG response is guaranteed by broken both inversion (IS) and mirror symmetries. The TRS WSM yields one left right nodes (WNs) there are two WNs for invariant WSM. show that these features can potentially cause quantization at higher values compare...

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...
