قدرت تفکیک دستگاه طیف‌نگار جرمی به صورت مستقیم شدت یون خروجی و انرژی آن بستگی دارد. مقدار تولید شده جریان باریکه الکترونی وابسته است. از جمله وظایف مدار کنترل چشمه برخورد تنظیم برای رسیدن بهینه می‌باشد. در ساخت پارامترهایی نظیر تثبیت آن، دقیق پتانسل الکتریکی لنز الکترودهای یونی بسیار حایز اهمیت این مقاله با قابلیت انتشار الکترون، پتانسیل نقاط طراحی ساخته شد. کنترلر بر روی طیف نگار 44Varian MAT ...

Given a coloring f : V (G) → IN of graph G and any subgraph H ⊂ G we define fs(H) = ∑ v∈V (H) f(v). In particular, we denote fs(G) by S(f). The coloring f is called an ICcoloring if for any integer k ∈ [1, S(f)] there is a connected subgraph H ⊂ G such that fs(H) = k. Also, we define the IC-index of G to be M(G) = max{ S(f) : f is an IC-coloring of G }. In this paper we examine some well-known ...

Using the idea of ic-open sets, we introduce and investigate topological qualities an ic-closure, ic-interior, ic-limit points, ic-derived, ic-border, ic-frontier, ic-exterior a set. Introduce concepts "ic-continuous mappings," "ic-open "ic-irresolute "ic-totally continuous "ic-homeomorphism," then look into some properties these mappings

More than a decade of research in the field of thermal, motion, vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results and their pow...

This paper describes the development and preliminary testing of a robotic device to facilitate minimally invasive beating-heart intrapericardial interventions. We propose the concept of a subxiphoid-inserted mobile robot (HeartLander) with the ability to adhere to the epicardium, navigate to any location, and administer therapy under physician control. As compared to current laparoscopic cardia...
