درست مسألة تفاعل ذرة ثنائية السوية مع أنموذج حقل إشعاع وحيد النمط فـي حالـة اللاتجـاوب ضمن ميكانيكا الكم. أعطيت عبارات القيمة المتوسطة للعدد الفوتوني و التطور الزمني للحركة الذرية. و تم الحصول على تواتر تبادل الطاقة بين السويات الذرية و حقل الأشعة في حـالتي التجـاوب و اللاتجـاوب. عرضت نتائج جميع شروط البدء للذرة - حقل الإشعاع. تمت المقارنة بين نتـائج التفاعـل اللاتجـاوبي و التفاعل التجاوبي.
The quantum mechanical analysis for a non-resonant case of a single radiation mode interacting with a two-level atom in a cavity is studied. Expressions for the mean value of photon number and the time evolution of the atomic motion are given. The frequency of exchange energy between the atomic levels and the radiation field systems for non- resonant and resonant interactions is obtained. Results for all initial states of the atom-radiation field are presented. Results for resonant and non-resonant interactions are compared.

This research aims to study and design a single mode optical fiber using simulation,
with a core and glass cladding, and also helps in ensuring the efficiency to use the optical
fiber designed within the broading window C-Band,and that these resear
ches and studies
tries to use this window. This research also shares to set the light on the Numerical
Programmes and Simulation used now in studying and designing these optical fibers. At
first we used the programOptifiberto reach the confidence of Sellmeier equation for the
fiber core, and this completed by using the finite element method solving the equation of
propagation the electric field and finding its 3-D distribution, using the famous simulating
COMSOLMultiphysics. This completed by putting the program MATLAB to reach the
two equation: the total dispersion and attenuation for the designed optical fiber.
Despite the technological developments that helped the decision-making process, the
decision maker remains its cornerstone. The decision-maker is a human being who
has feelings, affects and gets affected by the prevailing circumstances that, in tur
n,
affect the efficiency and effectiveness of decision-making. This research studies the
impact of personality that finger-prints the decision-making process. The research
looks for ways of improving the efficiency and effectiveness of decision-making by
the integration of the two components; personality and rationality. This will be
through following methods that enable getting the maximum amount of information
about the discussed problem, filter and summarize these information in order to
present accurate information that directly or indirectly lead to solve this problem.
This doesn’t happen through solely depending on the decision-maker’s previous
experience and expertise, but it is complimented by the efforts of the specialists in
this field. . The research found the use of logic in rational decision-making in the
Ministry of Higher Education, and the use of emotional logic in the decision-making
in the Ministry of Education with a relationship between the efficiency of the use
pattern both emotional and rational decision-making.
In this paper we compare Oxford Lexico and Merriam Webster dictionaries with Princeton WordNet with respect to the description of semantic (dis)similarity between polysemous and homonymous senses that could be inferred from them. WordNet lacks any ex
plicit description of polysemy or homonymy, but as a network of linked senses it may be used to compute semantic distances between word senses. To compare WordNet with the dictionaries, we transformed sample entry microstructures of the latter into graphs and cross-linked them with the equivalent senses of the former. We found that dictionaries are in high agreement with each other, if one considers polysemy and homonymy altogether, and in moderate concordance, if one focuses merely on polysemy descriptions. Measuring the shortest path lengths on WordNet gave results comparable to those on the dictionaries in predicting semantic dissimilarity between polysemous senses, but was less felicitous while recognising homonymy.
