This Research presents a detailed study and practical design for the construction, programming and implementation of the system to receive SMS messages sent from a mobile phone or more to the SIM card placed with in the circuit (GSM-MODULE) connected in turn with a microcontroller which translates and shows this message on the optical matrix.
The quick consuming of products and the strong competition between producers caused to increase the complexity of products, so the digital factory became a need between design and producing actually to achieve a production system with a shorter ti me and optimal design and parameters without engineering modifications. This research offering a reference model basing on a complete framework between the engineering applications to build a computational model with a single core based on the integration between three dimensions modeling and automation of application for digital factory concept, to optimize the design of achieving the ideal execution of actual production system. Where we achieved the control of three-dimensional computer model according to process automation exactly as in actual through integrating tools, where the percentage of exact between the real factory and digital factory was 83% by using the time of process as the main factor for comparison in this evaluation.
The majority of recent digital signature algorithms depend, in their structure, on complicated mathematical concepts that require a long time and a significant computational effort to be executed. As a trial to reduce these problems, some researchers have proposed digital signature algorithms which depend on simple arithmetic functions and operations that are executed quickly, but that was at the expense of the security of algorithms.
International river basins are characterized by their wide extent where mapping earth surface features and drawing contours by topographic team become–somehow- impossible because the cost and efforts consumed to execute it become very high and may exceed reasonable limits. Here it becomes necessary to use digital elevation models (DEM) inferred by specialized scientific organizations using remote sensing. There are several DEMs available on the internet and downloadable for free. The primary factor in defining the models efficiency in building hydrological models not the least cost but the maximum reliable results and better resolution that adequate to the capabilities of the PCs. In this study, three DEMs were used to derive and build hydrological models for the Euphrates-Tigris basin using Geographic information system techniques. The resulted boundaries of Euphrates-Tigris basin were compared with three boundaries implemented by international research organizations (UNEP, ESCWA, and FAO). As a conclusion of this comparison, the SRTM—3arc DEM was the most efficient model among used models. In addition, this study indicated the necessity to reevaluate Basin’s boundaries and correct the spatial distribution of proportion for basin area between the riparian countries.
