بررسی و مقایسه خواص سایشی پوششهای کرمی تهیه شده به روش آبکاری مستقیم و پالسی

در این پژوهش با استفاده از جریان مستقیم و پالسی پوششهای کرمی ترک دار و عاری از ترک تهیه شدند. بررسی سایش پوششها نشان داد که ضرایب اصطکاک و میزان سایش در نمونه های عاری از ترک بیشتر از نمونه های ترک دار است. بررسی های انجام شده نشان می دهد که مکانیزم اصلی سایش در نمونه های ترک دار می تواند سایش خستگی به همراه سایش خراشان باشد که باعث کنده شدن و شکستن پوشش از مناطق پرتنش می شود. در پوشش های عاری ...

Understanding Agility in ISD Projects

Since the 2001 publication of the Agile Manifesto, agile information systems development (ISD) methods have enjoyed increasing popularity. Extant research has highlighted critical challenges and key benefits associated with agile methods. Notwithstanding, the contribution of the actions performed by actors involved in an ISD project toward the achievement of agility remains unclear. This issue ...

Why Can't We Bet on ISD Outcomes: ISD "Form" as a Predictor of Success

The record of failure to deliver large-scale Information Systems (IS) in a timely fashion that offer value to major commercial and public organizations is legendary. Just looking to critical success factors such as top management support and user involvement in order to understand how to deliver better systems can at best be a partial solution. We seem to overlook an obvious area in our organiz...

A Philosophical Underpinning For ISD

If information systems development (ISD) is to be anything other than an ad-hoc discipline it must have a theory-like foundation. This paper interleaves philosophical discussion of ISD with practical suggestions. A philosophy with radically different presuppositions allows us to take a multi-aspectual view of I.S. that can address even tricky problems of multiple stakeholders and unintended and...

مشخصات پیوندگاه‌های ابررسانا - فرومغناطیس - ابررسانا با پایانه‌های ابررسانای یکتایی

We study numerically the electronic heat capacity, spin and charge current in a diffusive Superconductor-Ferromagnetic-Superconductor systems، with singlet superconducting leads and non-uniform ferromagnetic layer. Specially, we focus on ferromagnetic layer with domain wall and conical structures incorporation the spin-active interfaces. We investigate, how the 0-π transition is influenced by n...
