The whole system is divided into three subsystems, and each with its own direction. A layered architecture is used for the core services subsystem. Using the extended interfaces and services provided by the core service subsystem, the value-added services and functions are constructed. Users do not need to install the system and only need to open the browser for using the system. Thus the troubles caused by system upgrades can be avoided . For users, it is simple, fast start, and zero maintenance. OGIS is a set of public space data manipulation functions, which can be applied in any platform and system, making it possible for the users to use in a sole environment and a work flow and being suitable for any geography data distributed on the net. But the OGIS function collection is imperfect. It cannot provide unified standards for space data conversions of various levels and fields and it cannot completely solve problems of data centralism and distribution processing. The example proved that the method used in this paper has realized fast loss less transformation for the spatial data, which has a broad application in relative field.

With the continuous improvement of design complexity, higher requirements are placed on the model simulation design of high-precision and high-confidence. The paper analyzes the simulation process of 3D model and improves the feature extraction method in the process based on the research of OpenCASCADE platform. Firstly, the CAD platform geometry model is used to develop the model concept map, and then the model's three-view projection map is used to extract feature information; meanwhile, the complex surface adjustment and description are used to represent the model feature information. Finally, the graph feature vector obtained by the complex facet and transformation is calculated by using the maximum and minimum approximations as the distance between the feature references, so as to evaluate the similarity between the models. the experiment have shown that the projection mapping of complex surface adjustment can accurately identify the fluctuations of complex surfaces in the model, and facilitate the more precise acquisition of feature parameters. The related functions studied in the paper will help to further improve the development capability of 3D models based on OpenCASCADE, which can make the faster implementation of high-precision simulation design requirements.

In this paper, the gap flow field model of variable cross-sectional hole is established, the flow field with different oblique angle of liquid hole is simulated and analyzed. The simulation results show that designing rotating flow field with the outlet hole oblique angle of 45° can improve the electrolyte distribution in machining gap and greatly reduce the low speed zone. Under the conditions of processing voltage 10V, electrolyte inlet pressure 1.6MPa, electrolyte temperature 30°C and cathode feed speed 5mm/min, the electrochemical machining of variable cross-sectional hole was carried out by using the optimized cathode.

The cloudlet scheduling method relies on the environment and task type to accomplish the scheduling process in an algorithm supported by the visual machine programs. The paper captures the cloudlet network gains attributed to the increased use of cloudlet scheduling technique in tablets and mobile phones operated within the communication and data delivery platform. The system relies on improved storage space and processing speed with which the systems works with reference of minimizing power usage. The platform sustains efficient programming of tasks through the application of meta-heuristic algorithms. The paper focuses on AES algorithm and how it solves a given task at every instance while optimizing system efficiency. The beauty of the algorithm is efficient energy consumption in the data transfer platform that adopts the analysis in response to the task completion based on first-come-first-serve. The concept sustains the sequences of service delivery in the computing networks.
