Transmission-Model
无线传感器网络定位用到的无线传输模型
Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
(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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Surface-Tension
表面张力
规则是:
(1)对周围的 8 近邻的元胞以及自身的状态求和
(2)如果总和< 4 或= 5 ,下一时刻的状态= 0 否则状态= 1 (Surface Tension rules are: (1) around the 8 cell and its neighbor' s state sum (2) If the sum of < 4 or = 5, the next time state = 0 else status = 1)

WP7-Panorama-with-Caliburn.Micro1
The study consisted of an introduction, three scans performed
for each of the eleven scanners, and an adjacent
interview. We utilized a within-subject design. The dependent
variables were task completion time and reliability, by which
we mean the share of successful scans within a task completion
time below 15 seconds. The independent variables were the
barcode scanners as listed in Table 1. For each participant the
study was recorded on video. We also transcribed comments
the participant made during the tasks.
