Các chuyên ngành cơ bản của cơ khí bao gồm: động học, tĩnh học, sức bền vật liệu, truyền nhiệt, động lực dòng chảy, cơ học vật rắn, điều khiển học, khí động học, thủy lực, chuyển động học và các ứng dụng nhiệt động lực học. Các kỹ sư cơ khí cũng đòi hỏi phải có kiến thức và năng lực áp dụng những khái niệm trong môi trường kỹ thuật điện và hóa học. Với một mức độ nhỏ, cơ khí còn trở thành kỹ thuật phân tử - một mục tiêu viễn cảnh của nó là tạo. | 166 Data Acquisition Fig. 15. . Controll of the DC shunt motor rotation speed. 7. Conclusion Example applications presented above demonstrate the feasibility and robustness of Java based systems for data acquisition in distributed environments and although Java is the core technology of the system other execution environments can be integrated. This integration is made using a middleware technology. Being one of the most used middleware technologies Web Services were adopted in the current implementation. Besides these applications authors have also been using the presented approach to Distributed Data Acquisition Systems in other work areas. Some examples of those applications include DC-Motor speed control using Matlab Silva et al. 2008 Filling level gathering of recycle bins using Wireless signal attenuation acquisition for wireless propagation studies using Vegetation Growth detection. The use of Java has proven to be reliable and very useful allowing several different platforms to be used in the applications mentioned above. With this approach the examples presented in section 6 were implemented without having to concern about the target platforms. Applications and device drivers used in the testing scenarios were executed under Linux and Microsoft Windows family Operating Systems without any compatibility or performance issues. Although Java is the preferable platform to develop the system components and in fact it is presented as the core technology applications developed using other tools can also be integrated in the proposed architecture. A non-Java application that interacted with the device driver using Web Services implemented using LabView was presented. Being a widely adopted middleware technology Web Services allow to span the number of different platforms that can communicate with our system. Java in the Loop of Data Acquisition Systems 167 When using LabView a small wrapper application was used to convert .
