A comparison study on temperature measurement precision between middlewave 3-5m and longwave 8-12m measuring thermal imaging systems has been conducted. The study was limited to systems working in indoor conditions and the target's temperature is in the range of 270K900K. First
the Disturb Resisting Function (DRF) of infrared systems is deduced. On the base of DRF curve
we find that the middlewave infrared system get the smaller influences under the same size disturb compared with the longwave system. A theory of the influence of target's physical characteristic and measurement conditions on the accuracy of temperature measurements has been developed. On the basis of the developed formulas an analysis of the influence of signal disturbances (because of incorrectly assumed emissivity
limited transmittance of the atmosphere
radiation reflected by the object and shift of optics radiation) on the accuracy of temperature measurement has been made. It has been found that the middlewave systems in typical temperature range offer generally better accuracy in temperature measurement than the longwave ones do. 2012 IEEE.

Group elevator scheduling (GES) problem is an optimization problem. In this work
a robust optimization scheduling method is proposed to solve elevator group control system problem with passenger traffic flow uncertainty. An uncertain optimization model of elevator group scheduling is set up based on considering both energy consumption and waiting time. When considering the uncertainty of passenger traffic flow
the model is an uncertain optimization problem. It is tuned into its robust counterpart (RC) based on robust optimization theory. The simulation experiment presents the proposed scheduling method's scheduling performance. 2011 IEEE.

In this paper
the SNR tested in laboratory is better than 95 under typical working condition(the solar incidence degree is 30
the temperature of the focal plane module is controlled under 30 in a working period of 15 minutes. All of these results can satisfy the requirements about the synchronous photography
the authors introduced the theory about LMCCD (line-matrix CCD) mapping camera firstly. On top of the introduction were consists of the imaging system of LMCCD mapping camera. Secondly
the photography interval of line-matrix CCD of the nadir camera can satisfy the butter requirements of LMCCD focal plane module
the reflectivity of the earth's surface is 0.3) of each CCD image
the temperature control of focal plane module and SNR

As we know
the existence of image motion has a bad effect on the image quality of satellite-borne TDI CCD camera. Although many theories on image motion are proposed to cope with this problem
few simulations are done to justify the proposed theories on ground. And thus
in this paper
a ground-based physical simulation system for TDI CCD imaging is developed and specified
which consists of a physical simulation subsystem for precise satellite attitude control based on a 3-axis air bearing table
and an imaging and simulation subsystem utilizing area-array CCD to simulate TDI CCD. The designed system could realize not only a precise simulation of satellite attitude control
whose point accuracy is above 0.1 and steady accuracy above 0.01/s
but also an imaging simulation of 16-stage TDI CCD with 0.1s its integration time. This paper also gives a mathematical model of image motion of this system analogous with satellite-borne TDI CCD
and detailed descriptions on the principle utilizing area-array CCD to simulate TDI CCD. It is shown that experiment results are in accordance with mathematical simulation
and that the image quality deteriorate seriously when the correspondence between the image velocity and signal charges transfer velocity is broken out
which suggest not only the validity of the system design but also the validity of the proposed image motion theory of TDI CCD. 2010 SPIE.

In order to solve the conductive ring module's interference problems
measured the electromagnetic radiation of Power drive module
and used test results analysis the electromagnetic compatibility of the conductive ring
identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working
test equipment can not be fixed. Therefore
from the electromagnetic radiation theory
the paper analyzed the electromagnetic radiation of the power drive module. From it
determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results
calculate the interference voltage of wire in Conductive ring
and then determine the corresponding EMC method. The results show that
when The power drive module Radiate Electromagnetic waves
wires would coupled common mode interference voltage
its frequency is 3MHz
amplitude is about 10V
it would interfered the operation of sensor. By reducing the area of ground loops
used shielded cables
final rule out the interference. 2010 IEEE.
