TMT Segment Polishing Principles

چکیده
2. INSPECTION: Polisher receives and inspects the roundel. This should include measurement of the glass birefringence along the perimeter approximately where the hexagon is to be cut. These measurements are described in the Blank Specification and are the responsibility of the blank supplier. Keck experience is that this measurement was well correlated with the amplitude of the warping of the segment when it was cut from the roundel.

Estimation of normalized point-source sensitivity of segment surface specifications for extremely large telescopes.
We present a method which estimates the normalized point-source sensitivity (PSSN) of a segmented telescope when only information from a single segment surface is known. The estimation principle is based on a statistical approach with an assumption that all segment surfaces have the same power spectral density (PSD) as the given segment surface. As presented in this paper, the PSSN based on thi...
متن کاملHydraulic supports for polishing TMT M3MP
For polishing the ultra-thin TMT M3MP, a polishing support system with 18 hydraulic supports (HS) is introduced. This work focuses on the designing and testing of these HSs. Firstly the design concept of HS system is discussed; then mechanical implementation of the HS structure is carried out, with special consideration of fluid cycling, work pressurization and the weight component. Afterward t...
متن کاملHermeneutic Analysis of Transcendental Medicine Theory and its Application in Deep Medicine from the Perspective of Islamic Medicine Paradigm
The principles of Islamic medicine are still unknown. Although various studies about Islamic medicine have been carried out, the philosophical foundations and framework of the theorizing of it have not yet been elucidated. Some of theorists have explored transcendental medicine theory (TMT) and its application in deep medicine paradigm. For studying of theoretical framework of the TMT, the pres...
متن کاملThe Effects of Aging, Malingering, and Traumatic Brain Injury on Computerized Trail-Making Test Performance
The trail making test (TMT) is widely used to assess speed of processing and executive function. However, normative data sets gathered at different sites show significant inconsistencies. Here, we describe a computerized version of the TMT (C-TMT) that increases the precision and replicability of the TMT by permitting a segment-by-segment analysis of performance and separate analyses of dwell-t...
متن کاملCorrelation of ST Segment Elevation in the Lead aVR During tmt with Coronary Angiogram
BACKGROUND:Treadmill testing (TMT) is the most widely used method for evaluating patients with coronary artery disease, predicting the left main coronary artery (LMCA) disease before invasive procedure is very important in risk assessment because of its severe clinical outcome. Lead aVR can be very useful in identifying LMCA obstruction, it is also valuable lead not only in diagnosis but also i...
