Background: A society will be sustainable when the basic needs of all its citizens are met. On the other hand, the increasing population of urban areas has increased the demand for public services, especially health services. Today, the level and extent of residents' access to services are calculated on the basis of spatial justice. This study aimed to analyze the extent of realization of spati...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
Spatial applications require data on the general geography of regions; such data is generally collected outside the organizations using it. An electronic market offers a useful model for the supply and sale of spatial data. This paper discusses how such a market might operate for spatial data and compares it to existing markets for software and music. This comparison suggests that spatial data ...
Preface The authors would like to show the deepest gratitude to the supervisor Mr. Mohamed Hamid for his professional guide and supervision. With his help, we could finish our thesis work. Abstract Function generator has been widely used in each electronics fields recent years. In this thesis, the authors will introduce some basic structure and working principles of a function generator, moreov...
PURPOSE Anatomical background presents a major impediment to detectability in 2D radiography as well as 3D tomosynthesis and cone-beam CT (CBCT). This article incorporates theoretical and experimental analysis of anatomical background "noise" in cascaded systems analysis of 2D and 3D imaging performance to yield "generalized" metrics of noise-equivalent quanta (NEQ) and detectability index as a...
Using the Computational methods, the interaction effect of Tyrosine Amino acid on Graphene wasinvestigated. For this purpose, the Density Functional Theory (DFT) in the ground state of 6-31Gwas used, and the interaction effects of Tyrosine on Graphene was investigated through attachmentto three different base positions. Different parameters such as energy levels, the amount ofChemical Shift in ...
Using the Computational methods, the interaction effect of Glutamine Amino acid on Graphene was investigated. For this purpose, the Density Functional Theory) DFT (in the ground state of 6-31G was used, and the interaction effects of Glutamine on Graphene was investigated through attachment to two different base positions. Different parameters such as energy levels, the amount of Chemical Shif...
The electronic structure and spectra of 3-formylchromone and some of its derivatives are investigated using TD-DFT/B3LYB/6-311G (d, p) level of theory. The results of calculations show that all the studied compounds 1–6 are planar, as indicated from the dihedral angles. The electronic absorption spectra of the studied compounds are recorded in the UV-Vis region, in both ethanol (as polar solven...
