Mathematical Foundations of Computer Networking provides an intuitive yet rigorous introduction to these essential mathematical principles and techniques. Assuming a basic grasp of calculus, this book offers sufficient detail to serve as the only reference many readers will need. Each concept is described in four ways: intuitively; using appropriate mathematical notation; with a numerical example carefully chosen for its relevance to networking; and with a numerical exercise for the reader. The first part of the text presents basic concepts, and the second part introduces four theories in a progression that has been designed to gradually deepen readers’ understanding. Within each part, chapters are as self-contained as possible. The first part covers probability; statistics; linear algebra; optimization; and signals, systems, and transforms. Topics range from Bayesian networks to hypothesis testing, and eigenvalue computation to Fourier transforms. These preliminary chapters establish a basis for the four theories covered in the second part of the book: queueing theory, game theory, control theory, and information theory. The second part also demonstrates how mathematical concepts can be applied to issues such as contention for limited resources, and the optimization of network responsiveness, stability, and throughput. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 管內(nèi)機(jī)器人的開發(fā) 摘要:針對石油天然氣長輸管道焊接,采用焊口固定的全位置焊接,增加了大直徑、厚壁石油天然氣管道的焊接難度。在簡要分析大直徑、厚壁石油天然氣管道焊接、探傷、檢測現(xiàn)狀的基礎(chǔ)上,結(jié)合焊接施工現(xiàn)場的環(huán)境特點,介紹了一種適用于大直徑、厚壁石油天然氣管道焊接、探傷、檢測使用的管內(nèi)機(jī)器人,著重闡述了管內(nèi)機(jī)器人的機(jī)械結(jié)構(gòu)、控制系統(tǒng)硬件、控制軟件開發(fā)等關(guān)鍵技術(shù)問題。以及使用管內(nèi)機(jī)器人作為管道自動化作業(yè)平臺,以機(jī)電功能模塊,組裝各類專用管道機(jī)器人,實現(xiàn)大直徑、厚壁石油天然氣管道焊接、探傷、檢測的自動化。 ![]() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
