(Wireless sensor network localization using wireless transmission model, Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
Achieve functional distance and transmission attenuation swap
~~~~~~~~~~~~~~~~~~~~~~Regular Model~~~~~~~~~~~~~~~
In this model, the radio range is a circle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ReceivedSignalStrength=SendingPower-PathLoss
e.g, RSS=Pt-Pl(d0)-10*η*log10(dist/d0)
Pt:transmit power
pl(d0):the pass loss for a reference distance of d0
ηis the path loss exponent
above parameters are saved in ../Parameters_Of_Models.mat
dist:distance between sender and receiver(m)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
typical value:Pt=0-4dBm(max),Pl(d0)=55dB(d0=1m),η(2~4)=4(indoor,outdoor)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~Logarithmic Attenuation Model~~~~~~~~~
In this model, the radio range is a circle

T2F
T2F子函数，在做傅里叶变换时调用。我一开始编程序时忘了加它，结果WARN ME 说未定义T2F。(T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.)

C-17-flight-control-system-review
：文章从满足C 17设计基本要求人手，阐述了避免严重失速的机理、操纵失效概率、所有发动机停车操
纵以及安全复飞要求。对综合飞行控制系统设计做了介绍。对满足上述要求的FCS特性做了描述。最后对早期的飞行试验结果作了分析。(: Articles from the design to meet the basic requirements of C 17 staff, described the mechanism to avoid serious stall, control failure probability, all the engines go around parking control and security requirements. The integrated flight control system design is introduced. FCS on the properties meet the above requirements was described. Finally, the early flight test results are analyzed.)
