با توجه به الزامات زیست‌محیطی، اجتماعی و اقتصادی، طراحی شبکه زنجیره تأمین حلقه‌­بسته پژوهشگران زیادی را خود جذب کرده است. این مسئله بیشتر به‌صورت مجزا از ارزیابی تأمین‌کنندگان موردمطالعه قرار گرفته عوامل مختلفی به‌جز قیمت مانند ویژگی‌های تأمین‌کننده قطعه می‌تواند تأثیر بر عملکرد داشته باشد. در پژوهش یک شامل سایت‌های تولید، جداسازی، بازسازی دفع نظر مدلی تلفیقی سه مرحله ارائه شده نخست روش ترکیبی ...

Recently, echo state network (ESN) has attracted a great deal of attention due to its high accuracy and efficient learning performance. Compared with the traditional random structure and classical sigmoid units, simple circle topology and leaky integrator neurons have more advantages on reservoir computing of ESN. In this paper, we propose a new model of ESN with both circle reservoir structure...

PURPOSE To investigate the efficiency of electrical stimulation in the muscle maintenance and nerve regeneration after end-to-side neurorrhaphy (ESN). METHODS Sixty male Wistar rats (Rattus norvegicus) were divided into four experimental groups. Control group (Control), Denervated Group (Denervated); Group with End-to-side neurorrhaphy (ESN); Group with End-to-side neurorrhaphy and electrical...

Enterprise social networking (ESN) is widely used to facilitate employees’ communication and collaboration in today’s competitive business environment. However, the underlying mechanism through which ESN improves team performance is not clear. To address this gap, we propose that the ESN use may affect the building of transactive memory systems (TMS), which in turn influence team performance. S...

Enterprise social networking (ESN) is a relatively new phenomenon and not yet fully understood. An important reason for this lies in the fact that ESN are built on malleable technologies that do not lend themselves to immediate forms of workplace usage determined or prescribed by their features. Rather, their potential only manifests when people make sense of and incorporate them into their day...

Plasma concentrations of oestrogen stimulated neurophysin (ESN) were reduced in 28 patients with Alzheimer's disease (AD) compared with 14 age-matched controls, 16 patients with other presenile dementias and 12 patients with major depressive disorder. The ESN response to oestrogen challenge was delayed in 10 AD patients compared with 7 age-matched controls. Reduced basal and oestrogen stimulate...
