Working Efficiency

Nowadays, with the wide application of the geographic information system in water conservancy and hydropower projects, workload of three-dimensional digital model building the dam has become very large and complicated. However, the combining development of AutoCAD and ArcGIS can greatly reduce its workload and improve the working efficiency and modeling accuracy. This paper mainly conducts a preliminary study on dam three-dimensional modeling development in water resources and hydropower projects in the application of ArcGIS, and introduces the process of CAD data transferring into GIS data based on AutoCAD and its component technology.

Using ANSYS program, the finite element simulation based on thermoelectric coupling is conducted by a series of procedures, such as three-dimensional model building of airflow level posture sensor according to the actual size of the proportion, network modifying, loads applying and equation solving. The sensitive mechanism of airflow level posture sensor is explained by finite element method. The numerical results show that compared with two-dimensional modeling, the simulation result of three-dimensional modeling and thermoelectric analysis methods are more comprehensive and accurate, which provides more reliable basis for practical research of the airflow level posture sensor.

AbstractOrbitocranial reconstruction objectives include creation of a solid barrier between intracranial contents and the environment allowing restoration of physiologic homeostasis and restoration of aesthetic craniofacial contours. Historically, bone grafts have been used for reconstruction but were fraught with unpredictable resorption and imperfect contouring given the complex anatomy of the orbitofrontal bones. With advances in three-dimensional modeling technology, alloplastic custom implants in orbital and frontal bone reconstruction have allowed for rapid fixation reducing surgical times and improved cosmesis.

Using ANSYS-FLOTRAN CFD program, the finite element simulation is conducted by means of a series of procedures, such as three-dimensional model building of airflow level posture sensor, network modifying, loads applying equation solving, the flow field in three-dimensional hermetic chamber of sensitive element of airflow level posture sensor in different acceleration and inclination is Calculated, The numerical results show that for the sensor of airflow level posture sensor, the effect of acceleration and inclination is similar. Both of them can change the flow field of sensor, and will output a corresponding voltage. The simulation result of three-dimensional modeling is more comprehensive and accurate, which provides more reliable basis for practical research of the airflow level posture sensor.

Using ANSYS program, the finite element simulation based on Fluid-Solid coupling is conducted by a series of procedures, such as three-dimensional model building of airflow level posture sensor according to the actual size of the proportion, network modifying, loads applying and equation solving. The flow field in three-dimensional hermetic chamber of sensitive element of airflow level posture sensor is calculated. The numerical results show that: 1) The velocity difference of air flow at two heat source changes with the tilt angle, the difference between airflow velocity increases with the increase of the tilt angle. 2)Compared with two-dimensional modeling, the simulation result of three-dimensional modeling and fluid-solid analysis methods are more comprehensive and accurate, which provides more reliable basis for practical research of the airflow level posture sensor.

The article is devoted to the issues of using three-dimensional modeling as a way of information and technical support of forensic registration. It is stated that none of the modern researches focuses on the use of three- dimensional modeling technology of information and technical support of forensic registration. An assessment of the technological capabilities of modern three-dimensional scanners (3D-scanners), which are used (or can be used) in the information and technical support of forensic registration. The technological possibilities of three-dimensional modeling are analyzed, in particular in the construction of three-dimensional models of the scene, the creation of virtual rooms for educational purposes, forensic examinations, etc. Emphasis is placed on the fact that in criminology, three-dimensional (3D) modeling is carried out according to the rules of solid modeling (in which the key is to reproduce the physical properties of three-dimensional modeling objects). It is the physical properties of forensic registration objects, as a rule, that are the key information, the fixation of which is carried out within the framework of forensic registration. It is determined that the prospects of using three-dimensional (3D) modeling during forensic registration are to ensure the possibility of creating objects of accounting using additive technologies (ie three-dimensional printing (3D- printing)). The position is expressed that the technologies of three-dimensional (3D) modeling can be applied, first of all, in: trasological accounting; ballistic accounting; cold steel accounting; registration of persons on the basis of appearance; accounting of materials, substances and products. Therefore, with 3D modeling, it is possible to reproduce a certain three-dimensional object if it has been properly scanned. The described technologies create opportunities not only to quickly create exact copies or duplicates of evidence or other objects that are placed in forensic accounting, and use them for other research or for use as objects of orientation during operational or investigative actions.
