Without conceding a blemish in the first edition, I think I had best come clean
and admit that I embarked on a second edition largely to adopt a more geometric
approach to the detection of signals in white Gaussian noise. Equally rigorous, yet
more intuitive, this approach is not only student-friendly, but also extends more
easily to the detection problem with random parameters and to the radar problem
Over the past few decades there has been an exponential growth in service robots
and smart home technologies, which has led to the development of exciting new
products in our daily lives. Service robots can be used to provide domestic aid for
the elderly and disabled, serving various functions ranging from cleaning to enter-
tainment. Service robots are divided by functions, such as personal robots, field
robots, security robots, healthcare robots, medical robots, rehabilitation robots and
entertainment robots. A smart home appears “intelligent” because its embedded
computers can monitor so many aspects of the daily lives of householders. For
example, the refrigerator may be able to monitor its contents, suggest healthy alter-
natives and order groceries. Also, the smart home system may be able to clean the
house and water the plants.
This is a practical book, to be sure, but it is also a book about hope and posi-
tive change. I am quite sincere. The delivery of electricity is deeply rooted
in the principle of universal access; when clean, reliable energy is available it
contributes to poverty alleviation, improved social conditions, and enhanced
economic development. In the developed world, we know this to be true. The
digital fabric of our lives is a testimony to the importance of energy security.
Across the globe, we have seen the vital contributions that electrification has
brought to the development of economies and an enhanced quality of life.
Nonetheless, this supreme engineering achievement has languished, and we are
deeply challenged.
n its Framework and Roadmap for Smart Grid Interoperability Standards, the US
National Institute of Standards and Technology declares that a twenty-first-century
clean energy economy demands a twenty-first-century electric grid. 1 The start of the
twenty-first century marked the acceleration of the Smart Grid evolution. The goals
of this evolution are broad, including the promotion of widespread and distributed
deployment of renewable energy sources, increased energy efficiency, peak power
reduction, automated demand response, improved reliability, lower energy delivery
costs, and consumer participation in energy management.
Commercial energy storage has moved from the margins to the mainstream as it
fosters flexibility in our smarter, increasingly integrated energy systems. The
energy density, availability, and relatively clean fossil profile of natural gas ensure
its critical role as a fuel for heating and electricity generation. As a transportation
fuel, natural gas continues to increase its market penetration; much of this has been
enabled by emerging developments in storage technology.
為了確保最佳性能，請(qǐng)仔細(xì)閱讀本手冊(cè)。請(qǐng)將其保存在安全的地方，以備將來參考。將本機(jī)安裝在陰涼，干燥，清潔的地方-遠(yuǎn)離窗戶的熱源，過多的振動(dòng)灰塵，濕氣和冷源。避免嗡嗡聲的變壓器，電動(dòng)機(jī)。為避免起火或電擊，請(qǐng)勿使本機(jī)遭受雨淋或浸水。絕對(duì)不要機(jī)柜。如果有東西掉入設(shè)備中，請(qǐng)與經(jīng)銷商聯(lián)系。不要在開關(guān)，控件或連接線上用力。移動(dòng)設(shè)備時(shí)，請(qǐng)先拔下電源插頭和與其他設(shè)備相連的電線。切勿自己拉電線。機(jī)柜上的開口可確保設(shè)備正常通風(fēng)。如果這些開口被阻塞，則機(jī)柜內(nèi)部的溫度將迅速升高。因此，請(qǐng)避免將物品放在這些開口處，并將其安裝在后方10厘米，兩側(cè)20厘米，深30厘米9通風(fēng)條件確保設(shè)備的頂部面板至少留出一定空間。否則不僅會(huì)損壞設(shè)備，還會(huì)引起火災(zāi)。To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference Install this unit in a cool, dry, clean place -away from windows heat sources, sources of excessive vibration dust, moisture and cold.
