When optimizing the performance of neural network-based chatbots, determining the optimizer is one of the most important aspects. Optimizers primarily control the adjustment of model parameters such as weight and bias to minimize a loss function during training. Adaptive optimizers such as ADAM have become a standard choice and are widely used for their invariant parameter updates' magnitudes concerning gradient scale variations, but often pose generalization problems. Alternatively, Stochastic Gradient Descent (SGD) with Momentum and the extension of ADAM, the ADAMW, offers several advantages. This study aims to compare and examine the effects of these optimizers on the chatbot CST dataset. The effectiveness of each optimizer is evaluat

This study was to evaluate the role of garlic and melatonin in the reduction of the toxic effect of the drug methotrexate with concentrations 0.52 mg/ kg of body weight of rabbits on total count of white blood cells and enzymes liver functions, used in this study (90) of the male rabbits ,were randomly divided into five groups, six rabbits in each group, given all the animals normal food during the experimental period of 30 days, explained to the animals at the end of each period of experience and took blood samples to count white blood cells, measure liver function enzymes like Aspartate aminotransferase (AST), Alanine aminotransferase(ALT), Alkaline phosphatase (ALP), was reached the following conclusions: (1) The treatment of male rab

The last four decades have witnessed a number of rapid and successive international changes in terms of future impacts and orientations. International economy has transformed into a competitive small village due to the information technology revolution and the liberation processes and the economic openness that the market witnesses, there became one market and the activists in this international market are not governments only but rather international organizations and huge multinational corporations where each spares no effort to take every opportunity and face challenges within the frame of  removing all impediments and release transactions under the auspices of  these global developments, the idea of creating Islamic

      The service system has become a necessity of life in modern cities to be the most basic necessities of modern humans, they constitute a major base, which is based on the sustainability of life in the city and a standard measured through the degree of well-being and progress of civilized peoples and their interaction with the surrounding environment, making the services sector as a need not be an option, whenever the cities widened in population and space whenever provision of services and upgrading the quality and quantity more pressing, which made the subject of the services takes the biggest area of the trends and thinking of urban planners and those who in charge of drawing the cities policies. Consideri

To find the effect of interaction of the two elements , phosphorus and zinc, in some of the characters of two varieties of wheat (Triticum aestivum Var. Intisar) (Triticum aestivum Var. Ipa 95), An experiment was conducted in pots in the green house of the Department of Biological Science. / College of Education (Ibn-Al-Hiatham), for the season 2007/2008 using three levels of Phosphorus (0, 400, 800, mg / pot) and four levels of zinc (0, 10, 15, 20 mg / pot).  The experiment showed that the effect of the interaction of phosphorus and zinc was positive which increased the values of the features studied (length of plant, relative growth rate, nitrogen content, concentration of phosphorus and concentration of zinc) in the two varieties

   A potentiostatic study for the corrosion of pure zinc in 0.01 M HCl was achieved in absence and presence of (linear alkylbenzene solfonate LAS) detergents in a range of concentrations (0-50) mg/L. The electrochemical studies included anodic, cathodic polarization by using potentiostat over temperature rang (293- 323) K.     The mechanism of corrosion rate of pure zinc was suggested by evaluating of αa , αc , ba , bc , i0 , Rp and the kinetic parameters also calculated ( Ea , A) at the above temperature rang, The thermodynamic of corrosion, corrosion accelerating and corrosion  protecting were investigated by calculating  (∆G, ∆H and ∆s) values

The current research aims to identify (the effect of CORT program on creative thinking for middle school students in the art education history of ancient art subject).

     The research society continue of the5th of scientific students in ALsadreen secondary school of excellence which related of the Directorate of Education al-sader city, for the academic year (2015/2016), The sample was (35) students for each of the two groups (experimental and control). The equivalence between the research groups was carried out in the IQ variable, the age and the level of the father and mother.

     The researcher used the experimental method of partial control and the post-test. If the course of
