investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...

Global Stability of Oscillations Induced by aRelay

Suucient conditions of existence and global asymptotic stability of a limit cycle induced by a relay with hysteresis feedback in a linear time-invariant stable system are derived. The criterion is based on inspection of the open loop step response, combined with estimations of certain measures of its variance. Unlike the well-known describing functions method, the proposed approach yields a rig...

Polycentrism in Global Health Governance Scholarship; Comment on “Four Challenges That Global Health Networks Face”

Drawing on an in-depth analysis of eight global health networks, a recent essay in this journal argued that global health networks face four challenges to their effectiveness: problem definition, positioning, coalition-building, and governance. While sharing the argument of the essay concerned, in this commentary, we argue that these analytical concepts can be used to explicate a concept that h...

The Politics of Researching Global Health Politics; Comment on “Knowledge, Moral Claims and the Exercise of Power in Global Health”

In this comment, I build on Shiffman’s call for the global health community to more deeply investigate structural and productive power. I highlight two challenges we must grapple with as social scientists carrying out the types of investigation that Shiffman proposes: the politics of  challenging the powerful; and the need to investigate types of expertise that have traditionally been thought o...
