The Quality of the Lincoln Calibration Sphere
Due to the relatively high background noise level of the radar range used to measure the Lincoln Calibration Sphere (LCS) before launch, the upperbound estimates of the backscattering cross section variation made at the time included a large contribution generated by the range itself. By comparing the range measurements and the mechanical measurements made on the LCS with measurements made on t...
متن کاملon the relationship between different discourse markers and information-gap and reasoning-gap tasks, and the effectiveness of input enhancement type of instruction on students acquisition of discourse markers.
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
15 صفحه اولA paramagnetic molecular voltmeter.
We have developed a general electron paramagnetic resonance (EPR) method to measure electrostatic potential at spin labels on proteins to millivolt accuracy. Electrostatic potential is fundamental to energy-transducing proteins like myosin, because molecular energy storage and retrieval is primarily electrostatic. Quantitative analysis of protein electrostatics demands a site-specific spectrosc...
متن کاملCalibration sphere for low-frequency parametric sonars.
The problem of calibrating parametric sonar systems at low difference frequencies used in backscattering applications is addressed. A particular parametric sonar is considered: the Simrad TOPAS PS18 Parametric Sub-bottom Profiler. This generates difference-frequency signals in the band 0.5-6 kHz. A standard target is specified according to optimization conditions based on maximizing the target ...
متن کاملLinear Catadioptric Camera Calibration from Sphere Images
A spherical object has been introduced into central catadioptric camera calibration through utilizing the properties of an image conic, which is the projection of the occluding contour of a sphere in the catadioptric image. However, previous calibration method using sphere images employs nonlinear optimization method and requires a good initial estimation to start the minimization. In this pape...
