5 Test Data Evaluation In moving away from a quality assurance strategy, which simply carries out an in- spection, and the increased implementation of error avoidance, a fundamental change has taken place in the field of test data evaluation. Today, test data is no longer used only to demonstrate that manufactured products conform to specifica- tions, but is also increasingly implemented as an indicator for early detection of process errors (Figure 5-1).

Abstract

Optical interferometers as non-contact measurement devices are very desirable for the measurement of surface roughness and topography. Compared to phase shifting interferometers (PSIs) with a limited measurement range and a scan step of maximum λ/4, the optical interferometers like low coherence interferometers (LCIs) evaluating the degree of fringe coherence allow a larger vertical measurement range. Their vertical measurement range is only limited by the scan length allowed by the linear piezo stage and the coherence length of the light source. To evaluate the obtained data for a large range, the common LCIs require much computation time. To overcome this drawback, we present an evaluation algorithm based on the Hilbert-Transform and curve fitting (Levenberg–Marquardt algorithm) using Compute Unified Device Architecture (CUDA) technology, which allows parallel and independent data evaluation on General Purpose Graphics Processing Unit (GPGPU). Firstly, the evaluation algorithm is implemented and tested on an in-house developed LCI, which is based on Michelson configurations. Furthermore, we focus on the performance optimization of the GPU-based program using the different approaches to further achieve efficient and accurate massive parallel computing. Finally, the performance comparison for evaluating measurement data using different approaches is discussed in this paper.

Many polymer chemists still use unreliable and outdated methodologies to obtain reactivity ratios, including poor experimental design, incorrect statistical procedures, and failure to account for uncertainties in the experimental data. There is thus a clear need for a standardized, easy to implement and unbiased method for the determination of reactivity ratios in copolymerization. The objective of this recently initiated project is to outline robust methodologies to determine reactivity ratios, combining experimental procedures with correct data evaluation. The

_ Chemical Kinetic Data Evaluation for Atmospheric Chemistry and the IUPAC Kinetics Database It is well established that emissions from human activities are leading to important changes in the composition of the global atmosphere. The impact of emissions on air quality on local and regional scales has been recognized for decades. The importance of intercontinental and global transport of air pollutants is now becoming apparent. More recently, it has become clear that anthropogenic emissions of greenhouse gases and aerosols are responsible for radiative forcing of

Abstract

The effect of the hydrothermal modification (HTM) of the deciduous woods birch and aspen on their sorption behavior has been investigated by the vapor sorption method. An analysis of the experimental results was carried out based on the concept of Hansen solubility parameters (HSP), which takes into account the contribution of different forces – dispersion forces, dipole action, and hydrogen bonding – to the total cohesion energy. Sorption isotherms were measured concerning the vapors of water, methanol, and ethanol with unmodified and HTM woods at 160°C and 170°C during 3 and 1 h, respectively. The choice of sorbates was based on the parts of the hydrogen bonding and dispersion force to cohesion energy, in decreasing order of the former and increasing order of the latter. As a criterion of sorption, the value of the monolayer capacity was used, which was derived from the Brunauer-Emmett-Teller equation. Vapor sorption with unmodified and modified wood increased with increasing dispersion force component of the HSP of the sorbate. However, more substantial increase occurred for HTM wood, that is, wood surface became more hydrophobic. The reason for this observation is the change in the decreasing ratio holocellulose/lignin upon HTM. However, the chemical structure of lignin is also changed by HTM.
