پایش پیوسته ی سلامت ساختاری مبتنی بر امپدانس/ادمیتانس الکترومکانیکی به روش پوشش دهی فیلم ضخیم فعّال پیزوالکتریک به منظور تشخیص پیدایش آسیب در ساختارهای فلزی، غیرفلزی و سوپرآلیاژ در شرایط ساکن و متحرّک مورد بررسی قرار گرفته است. این روش یکی از موثرترین راهکارهای پیش بینی آسیب، ارتقای سطح ایمنی، کاهش هزینه ها و بررسی طول عمر قطعات صنعتی در سازه های مختلف از جمله توربوفن ها، کمپرسورها، رآکتورها، تور...
IMPORTANCE Psychiatric disorders in youth characterized by behavioral and emotional dysregulation are often comorbid and difficult to distinguish. An alternative approach to conceptualizing these disorders is to move toward a diagnostic system based on underlying pathophysiologic processes that may cut across conventionally defined diagnoses. Neuroimaging techniques have potentials for the iden...
Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...
Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
abstract: nowadays, the non-traditional processes such as “laser, edm and awj” used for cutting high thickness sheet metal. hardox is hard and tough steel alloy and it has many industrialize applications. one best process to cut the hardox is abrasive water jet (awj) cutting. it can cuts complex shape with high quality and accurate tolerance. awj cutting offers certain unique benefits such as...
We consider the problem of fair division of a two dimensional heterogeneous good among several agents. Applications include division of land as well as ad space in print and electronic media. Classical cake cutting protocols either consider a one-dimensional resource, or allocate each agent several disconnected pieces. In practice, however, the two dimensional shape of the allotted piece is of ...
in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...
