IMAGE-TO-MAP CONFLICT DETECTION USING ITERATIVE TRIMMING : APPLICATION TO FOREST CHANGE
trimming change vector kernel density estimate
2015/11/16
Large scale vector databases are valued tools for forest management. It is therefore important to keep these databases up to date and
various change detection methods have been designed in this aim. ...
Broadening Adjustable Range on Post-Fabrication Resonance Wavelength Trimming of Long-Period Fiber Gratings by Heating
Broadening Adjustable Range Post-Fabrication Resonance Wavelength Long-Period Fiber Gratings
2009/7/16
The adjustable range of resonance wavelengths of long-period gratings was broadened toward the blue side by heating, and the mechanism was studied. The large blue shift, 41 nm, was obtained by heating...
The Influence of Air-Abrasive Trimming on the Current Noise of Thick Film Resistors
Air-Abrasive Trimming Thick Film Resistors
1984/1/1
In the work cited the authors investigated the influence of trimming on current noise, if
the resistors differ by the same scaling factor before and after trimming. These are the cases
in which the ...

Hybrid Integrated Circuits the microelectronics industry passive techniques
1983/10/1
One of the more important fields of the microelectronics industry is the manufacturing of hybrid integrated circuits.An important part of the manufacturing process is concerned with the trimming of th...
The Effect of High Speed Laser Trimming on Accuracy and Stability of Thick Film Resistors
High Speed Laser Trimming Thick Film Resistors
1981/1/1
Many recommendations have been made on the proper operating conditions for the laser trimming process. In general these recommendations have centered on accuracy, precision or throughput. In some inst...
Thick-Film Laser Trimming Principles, Techniques and Recommendations
Thick-Film Laser Trimming Principles Techniques Recommendations
1981/1/1
Trimming plays an essential role in the manufacture of thick-film resistor networks. The process used to define circuit elements on a substrate, based on silk-screening techniques, is fast and inexpen...
The Influence of Air-Abrasive Trimming on the Current Noise of Thick Film Resistors
Air-Abrasive Trimming the Current Noise of Thick Film Resistors thick film hybrid circuits
1981/1/1
The purpose of this study was to investigate the effect of some air abrasive trim cuts on the current noise of thick film resistors. It was found that the current noise changed on trimming the resisto...
Functional Laser Trimming of Automotive Electronics
Functional Laser Automotive Electronics
1981/1/1
This paper discusses the use of laser trim systems for the trimming of automotive hybrids. Being high volume parts these devices are best trimmed in two stages; first, a passive trim of the resistor s...
Functional Trimming of Thick-Film Active Filters for Consumer and Industrial Applications
Thick-Film Active Filters Consumer and Industrial Applications
1980/3/13
Active filters, realized in thick film circuitry, can offer major advantages over more conventional wiring systems, including the ability to functionally trim them, using a computerized laser trimming...
