... algorithm failed to converge providing negative stiffness for some of the elements. The team performed root cause analysis considering several possible sources of errors and identified that the amplitude error and phase-shift error, shown in Figure 6, are the main contributing factors to the non-convergence. Accelerometers are supplied with a calibration factor to convert accelerometer's output voltage into acceleration unit. ...
Context 2
... phase-shift error, as shown in Figure 6, is generally caused by data latency and the numerical integration of noisy signal. However, the primary source of the phase-shift error is the integration of the measured acceleration time-histories to obtain velocity and displacement time-histories. ...

In this study, the concentrations of 24 elements, which are suspicious to be found in drinking and utility waters for the province of Antalya/Turkey, were determined using an inductively coupled plasma-mass spectrometer (ICP-MS). Validated methods with a low limit of detection are required to analyze such waters. The method was validated considerin...
The probe tip of a micro-coordinate Measuring Machine (micro-CMM) is a microsphere with a diameter of hundreds of microns, and its sphericity is generally controlled within tens to hundreds of nanometers. However, the accurate measurement of the microsphere morphology is difficult because of the small size and high precision requirement. In this st...
The development and use of new thermal insulation products in many industrial sectors, ranging from building insulations to power generation or satellite applications, requires the accurate knowledge of the radiative properties of the investigated material, i. e. its emissivity.

This work aims to determine the radiance responsivity to be used in the calibration of polychromatic radiation sources with low uncertainty. To realize the radiance, Ar-ion, He-Ne, and Nd-YAG lasers as well as an integrating sphere with a 0.15 m diameter are used to obtain radiation sources having Lambertian distributions. Then, a silicon photodiod...
The timing follow-up of newly discovered millisecond pulsars (MSPs) is hindered by the larger positional uncertainty (a few tens of arcminutes) associated with the discovery. In this paper, we present the localization of two MSPs, discovered by the GMRT High Resolution Southern Sky survey, up to arcsecond accuracy using a 33 MHz offline coherently...
