Customer value determines how products and services succeed in the marketplace. Early assessment of customer value is important for software startups, spin-o↵ companies, and new product development in existing companies. Software technology often influences customer value and typically defines the main competitive advantage in both entrepreneurial and intrapreneurial settings. Value-related fee...
We investigated the magnetic behaviour of an Fe overlayer on a Ni buffer layer (Fe/Ni multilayer system) grown top Fe-p(1 × 1)O surface, with particular focus modifications observed in spin-resolved electronic structure and role oxygen, introduced system well-defined amount at substrate preparation stage. The structural properties are by means low energy electron diffraction, that confirms form...
The adiabatic description of molecular electronic states is based on potential energy surfaces, defined by the motion of the electrons, on which the slower nuclear motions (vibrations and rotations) occur. However, this model breaks down when relativistic effects such as the coupling between the electron spin and its orbital angular momentum (spin-orbit coupling) are taken into account. The res...

در این پایان نامه ابتدا به بررسی مکانیزم های مختلف نقض لورنتس می پردازیم و در ادامه اثر نقض تقارن لورنتس را بر حرکت یک الکترون در تله مورد بررسی قرار می دهیم. برای این کار با استفاده از لاگرانژی نسبیتی نقض لونتس در مدل استاندار تعمیم یافته و تبدیل فولدی وات هاوزن و همچنین استفاده از جفت شندگی کمینه، هامیلتونی یک فرمیون جرم دار در میدان الکترومغناطیس را بدست می آوریم. برخلاف کارهای قبلی که از جم...
در این پایاننامه، ابتدا به معرفی یک ضرب خارجی لایه پرداخته شده است و شرط ??r لایه بپذیرد بیان شده ??r که یک فضای برداری، یک ضرب خارجی ?? لازم و کافی برای این را تعریف کرده و در آخر نشان داده شده است که spin(7) و g است. در ادامه خمینه 2 است. g یک خمینه 2 s1 x تایی باشد آنگاه ? ?? یک خمینه کالابی-یائو 3 1
Abstract This lecture introduces various kinds of spin rotating devices used in present particle accelerators. They include Siberian Snakes for polarization preservation and rotators creating a specific orientation experimental locations. Following the analysis rotation different types magnets, approaches designing are discussed. Considerations appropriate design choices dependence on beam ener...
the ground state rotational bands of some rare earth nuclei show a rather strange behaviour at large values of angular momenta. the nuclear moment of inertia teta increases smoothly with angular momentum i up to i=12. then at about i=14 there is a sudden increase in the moment of inertia. the plot of teta versus the square of the angular velocity w gives a s-shaped curve. we attempt here to rep...
In this paper, spin-dependent electrical transport properties are investigated in a single-crystal magnetic tunnel junction (MTJ) which consists of two ferromagnetic Fe electrodes separated by an MgO insulating barrier. These properties contain electric current, spin polarization and tunnel magnetoresistance (TMR). For this purpose, spin-dependent Hamiltonian is described for Δ1 and Δ5 bands in...
in this study cognitive therapy based on self-talking technique for reducing the rate of social phobia and factors of interpretation of events related to self and others have been noticed.sample group was 8 women from a 16-person group suffering from social phobia , selected at random from among 27 people referring to counseling clinics.their disorder has been detected by using the instrument o...
