Objective: The main objective of the study is to deepen the concepts of Smart City and Sustainability to propose a Sustainable Smart City model for the areas of Economy, Government, Environment, Mobility, Smart Society and Quality of Life. Methodology: To achieve the main objective, a review of the existing scientific literature on smart Cities, sustainability and it is areas of influence and indicators; has been carried out. Subsequently, an analysis of three Smart Cities was made and, finally, a proposal for a Sustainable Smart City model was made. Results: Several indicators have been presented for the six areas: Economy, Government, Environment, Mobility, Smart Society and Quality of Life. These areas allow improving and facilitating the quality of life of its citizens while maintaining a balance between the economic, social and environmental fields. In addition, a model is proposed for each area that includes sustainability. Limitations: The formulation of the Sustainable Smart City model has not considered the cost of applying the indicators presented for the area. Practical implications: Among the contributions, the formulation of the concept of Sustainable Smart City stands out, as well as its indicators. Finally, a Sustainable Smart City model is projected according to the above presented.

Ibm Pc

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

The imaging performance of the light optical lens systems has reached such a degree of perfection that nowadays numerical apertures of about 1 can be utilized. Compared to this state of development the objective lenses of electron microscopes are rather poor allowing at most usable apertures somewhat smaller than 10-2 . This severe shortcoming is due to the unavoidable axial chromatic and spherical aberration of rotationally symmetric electron lenses employed so far in all electron microscopes.The resolution of such electron microscopes can only be improved by increasing the accelerating voltage which shortens the electron wave length. Unfortunately, this procedure is rather ineffective because the achievable gain in resolution is only proportional to λ1/4 for a fixed magnetic field strength determined by the magnetic saturation of the pole pieces. Moreover, increasing the acceleration voltage results in deleterious knock-on processes and in extreme difficulties to stabilize the high voltage. Last not least the cost increase exponentially with voltage.
