We review the current applications of photonic technologies to Smart Cities. Inspired
by the future needs of Smart Cities, we then propose potential applications of advanced
photonic technologies. We find that photonics already has a major impact on Smart
Cities, in terms of smart lighting, sensing, and communication technologies. We further
find that advanced photonic technologies could lead to vastly improved infrastructure,
such as smart water‐supply systems. We conclude by proposing directions for future
research that will have the greatest impact on realizing Smart City initiatives.

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.

With all the recent hype over radio frequency identification (RFID) and
the requirements to implement it, you might think that RFID can turn
water into wine, transform lead into gold, and cure the world’s diseases. You
might also be worried that RFID will enable Big Brother to track your move-
ments to within a foot of your location from a satellite five hundred miles up
in space. The truth is, RFID can do none of these things.
In this chapter, you find out the basics of what RFID is, what forces are dri-
ving RFID as a replacement for the bar code in the marketplace, and what
benefits RFID can offer

There’s a story (it’s either an old vaudeville joke
or a Zen koan) in which a fisherman asks a fish,
“What’s the water like down there?” and the
fish replies “What is water?” If the story is just
a joke, the point is to make us laugh; but if it’s
a koan, the point is that the most obvious and
ubiquitous parts of our immediate environ-
ment are, paradoxically, often the easiest to
overlook.

The present work, Advanced Process Engineering Control, is intended to be the
continuation of the authors? Basic Process Engineering Control published by
DeGruyter in 2014. It presents the main and conventional type control loops in process
industries. Titles containing the concept of process engineering were deliberately
chosen to suggest the inclusion, within the same approach, of processes other than
the traditional ones. These come from outside the traditional fields of chemistry and
petrochemistry: the sphere of pharmaceuticals, wastewater management, water puri-
fication, water reserve management, construction material industry, food processing,
household or automotive industries.

在傳統(tǒng)智能小車驅(qū)動(dòng)電路設(shè)計(jì)中,較多考慮使用直流電機(jī)還是步進(jìn)電機(jī),電機(jī)功率、能耗等性能參數(shù)。使用具有armCortexM4內(nèi)核的STM32嵌入式平臺(tái)控制四輪的4個(gè)直流電機(jī)。文章基于PWM技術(shù)及PID算法,對(duì)四輪進(jìn)行精準(zhǔn)地速度、轉(zhuǎn)向及啟停控制,實(shí)驗(yàn)表明此小車具有優(yōu)越各種地形適應(yīng)能力。In the traditional intelligent car drive circuit design,DC motor or stepping motor,motor power,energy consumption and other performance parameters are considered.The four DC motors with four wheels are controlled by STM32 embedded platform with arm Cortex M4 kernel.Based on the PWM technology and PID algorithm,the accurate ground speed,steering,and start-stop control of the four wheels are carried out.The experiment shows that the vehicle has the superior adaptability to all kinds of terrains.
