  • ptc公司的proe高級曲面擴展教程

    在Pro/ENGINEER中,當創建或處理非實體曲面時,使用的是面組。面組代表相連非實體曲面的“拼接體”。面組可能由單個曲面或一個曲面集合組成。 面組包含了描述所有組成面組的曲面的幾何信息,和面組曲面的“縫合”(連接或交截)方法信息。一個零件包含多種面組。通過使用“曲面特征”創建或處理面組。 使用曲面功能 從“特征類”菜單中選擇“曲面”,顯示“面組曲面”還是“曲面選項”菜單,取決于模型中是曲面還是曲線。如果曲面特征或基準曲線存在于模型中,系統將顯示“曲面選項”菜單,它可用于創建新曲面。 也可以通過“插入”菜單來使用多數曲面命令。 命名面組可以使用命令序列“設置”/“名稱”/“其它”,為整個面組或單獨的曲面分配名稱。然后可以使用“獲得選取”中的“按菜單選取”選項,按名稱選擇已命名的面組或曲面。

  • 為您的FPGA選擇合適的電源

    Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/tracking and the voltage ripple limits. This application noteexplains these and other power-supply considerations that an ENGINEER must think through whendesigning a power supply for an FPGA.

  • 無線通信網絡基本概念及設計

    This white paper raises some fundamental issues the design ENGINEER should address before deciding upon a communication approach for a wireless network. As no universal wireless network solution exists, it should be custom tailored to suit the application demands. Defining your application communication characteristics is the key to ensure optimal communication reliability and resistance to interfering noise sources.

  • SAE J1939協議分析指南

    SAE J1939協議是由汽車工程協會(SAE)定義的,SAE J1939協議在商用車輛、艦船、軌道機車、農業機械和大型發動機中是應用最廣泛的應用層協議,基于傳輸可靠性能優越的CAN-bus總線,可達到250Kbps的通訊速率。在協議中,不僅指定了傳輸類型、報文結構及其分段、流量檢查等,而且報文內容本身也做了精確的定義,SAE J1939協議由美國SAE( Society of Automotive ENGINEER)組織維護和推廣

  • 半導體器件物理與設計

    It would not be an exaggeration to say that semiconductor devices have transformed humanlife. From computers to communications to internet and video games these devices and the technologies they have enabled have expanded human experience in a way that is unique in history. Semiconductor devices have exploited materials, physics and imaginative applications to spawn new lifestyles. Of course for the device ENGINEER, in spite of the advances, the challenges of reaching higher frequency, lower power consumption, higher power generation etc.

    Beginning with an introduction to 802.11b in general, 802.11 Security gives you a broad basis in theory and practice of wireless security, dispelling some of the myths along the way. In doing so, they provide you with the technical grounding required to think about how the rest of the book applies to your specific needs and situations. If you are a network, security, or systems ENGINEER, or anyone interested in deploying 802.11b--based systems, you ll want this book beside you every step of the way.
