We request support to develop a proposal for a new, sensitive method of searching for an electric dipole moment (EDM) of charged particles in a magnetic storage ring. The ring design is based on forced synchrotron oscillations that accumulate an EDM signal with each oscillation. Slow extraction of the beam onto a target provides a scattered flux whose asymmetry as a function of the time during ...
Existing manufacturing industries are fronting challenges from these advanced nasent materials viz. nano material ,ceramics, super alloys, and metal matrix composites, that are hard and difficult to machine, requiring high accuracy, surface quality excellence which affects and increases machining cost. To meet these tasks, unconventional machining processes are being used to achieve optimum met...
In the present paper influence of tensor electric and magnetic polarizabilities on spin evolution in the resonance deuteron EDM experiment is considered in details. It is shown that besides EDM the electric and magnetic polarizabilities also contribute to the vertical spin component P3. Moreover, the electric polarizability contributes to the P3 component even when the deuteron EDM is supposed ...
This study explored the 5 subconcepts (empowerment, flexible environment, personal knowledge, reflection, and social norms) of the Wittmann-Price Theory of Emancipated Decision Making (EDM) in women's healthcare, a theoretical model. Pain management for labor was the clinical exemplar. The correlation of EDM and satisfaction with the decision (SWD) was measured, and flexible environment was the...
Precision measurements of the Stark shifts in alkali-metal atoms @1,2# have been used to refine the calculations of alkali-metal atomic wave functions, motivated, in part, by precision parity nonconservation measurements in Cs. Hg atoms are used to set one of the most significant limits on a permanent electric dipole moment ~EDM! @3#. The search for an EDM does not require very precise atomic c...
دراین پایان نامه، خصوصیات شکست الکتریکی دی سی با حضور میدان مغناطیسی بررسی شده است. برای کاهش مقدار پتانسیل شکست الکتریکی، راههای متعددی وجود دارد، مانند استفاده از یک فیلامان، میدان مغناطیسی محوری و عمودی. در اینجا ما، اثرات میدان مغناطیسی محوری را بر روی ویژگی های شکست الکتریکی بررسی نمودیم. دستگاه ما شامل دو استوانه ی هم محور و یک سیم پیچ مغناطیسی برای تولید میدان مغناطیسی محوری در حضور گاز...
نانولوله¬های کربنی موادی جالب با ویژگی¬های مکانیکی و الکترونیکی فوق العاده¬ای هستند. نانولوله¬های کربنی می¬توانند فلزی یا شبه¬رسانا باشند. هر دو نوع ویژگی¬هایی دارند که مواد متعارف را به مبارزه می¬طلبند. ماهیت الکترونیکی یک بعدی این مواد منجر به بیشترین میزان حساسیت به تغییرات انرژی موضعی می¬گردد که برای یک قطعه به عنوان حسگر خاصیتی ایده¬ال و مطلوب است. در حال حاضر روشی برای تولید نانولوله¬های...
Educational Data Mining (EDM) is an emerging interdisciplinary research area that deals with the development of methods to explore data originating in an educational context. EDM uses different computational approaches to analyze educational data in order to study educational questions. Different data mining techniques has been applied in this area. One of the most widely used techniques in EDM...
Data from the muon g-2 experiment at Brookhaven National Lab has been analyzed to search for a muon electric dipole moment(EDM), which would violate parity and time reversal symmetries. An EDM would cause a tilt in the spin precession plane of the muons, resulting in a vertical oscillation in the position of electrons hitting the detectors. No signal has been observed. Based on this analysis, a...
Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engine...
