Application of PC-SAFT Equation of State to Bitumen/Solvent Systems
… Statistical Associating Fluid Theory (PC-SAFT) to bitumen and solvent mixtures. New binary interaction coefficient correlation and bitumen characterization method are developed to model the solubility, density and viscosity of such mixtures. These results are also integrated into the …

U-SAFT⁹⁰ simulates the internal and external loads of university-level soccer match play
… audio commands to the subjects completing the USAFT⁹⁰ course of multilateral soccer-specific movements. The CD was created by using average velocities from discreet movement categories, together with the average distances covered in each zone, using the data from the first study. Validation of …

Analysis of platinum, palladium and rhodium at trace concentrations in lead using the time resolved spark emission technique called SAFT
The fire assay technique may be used to extract noble metals from platinum bearing ores. It allows for the use of relatively large quantities of ore sample from which trace quantities of noble metals are concentrated. The fire assay with lead as the collector is one such procedure, where …

Applying synthetic aperture, coded excitation, and tissue harmonic imaging techniques to allow ultrasound imaging with a virtual source
… was the synthetic aperture focusing technique (SAFT), a well-studied method that allows focus at every distance instead of just one distance. Using this method, lateral resolution is restored and signal-to-noise ratio (SNR) is increased due to the compounding of several scan lines. SAFT was …

Transfer Learning for Accelerated Process Development
… for predicting activity coefficients and ML-SAFT for predicting PCP-SAFT parameters, showing steps towards improving thermodynamic predictions using transfer learning. Together, all of these studies demonstrate the potential of transfer learning to accelerate process development, providing …

Thermodynamische Untersuchungen von Phasengleichgewichten in komplexen Systemen mit assoziierenden Komponenten
… Associating Fluid Theory (PC-SAFT) which contain both a term to consider explicit hydrogen bonds. In addition, the predictive capabilities of the equations of state (EoS) were investigated. With parameters obtained by simultaneous fitting of VLE and, if available, LLE data …

Enhanced ultrasonic techniques for inspection of pressure tubes
… Synthetic Aperture Focusing Technique (SAFT) has been applied to industrial inspection data where the ultrasonic image performance is poorly-focused. The transducer focal point operates as a virtual source to transmit ultrasound with a corresponding beam angle. Subsequently, the …

Ultrasonic sensor platforms for Non-Destructive Evaluation
… The Synthetic Aperture Focusing Technique (SAFT) was evaluated as a means of improving the fidelity of B-Scan data. It was found that a SAFT is only effective for transducers with reasonably wide beam divergence, necessitating small transducers with a width of approximately 5mm. Finally, an …

Modelling approaches for rational solvent selection in drug development, enhancing the solubility prediction of small molecules
… including: COSMOtherm, NRTL-SAC, UNIFAC, and SAFT-γ Mie.;This work will focus on the use and appraisal of ab initio method COSMOtherm and the application of a "correction factor" using the machine learning algorithm random forest to improve accuracy of predictions. Chapter Two compares …

Auswirkungen von hohem hydrostatischem Druck auf Schimmelpilze und die Synthese des Mycotoxins Patulin
… von Patulin durch P. expansum wurde in Apfelsaft untersucht. Das Ana-lyseverfahren mittels HPLC wurde neu entwickelt. Durch diese Methode läßt sich Patulin vollständig von 5-Hydroxymethylfuraldehyd (5-HMF), einem in Apfelsaft vorkommenden Zersetzungsprodukt von Kohlenhydraten, trennen. Die …

Design of a parallel-series hybrid electric vehicle using multi-objective optimization techniques
… tests results for two nickel-cadmium batteries (Saft Nife STM1.130 and Marathon 44SP100) along with the Eastern-Penn RV31 are presented. The Universal Battery Model was slightly modified and used to evaluate analytically the energy and power density of the RV31, STM1.130, and 44SP100 battery …

Acid gas removal from natural gas using ionic liquids
… chain statistical association fluid theory (PC-SAFT) is selected as the thermodynamic model to represent the vapour liquid equilibrium of acid gases-IL systems.;The solubility of gases in ILs was successfully described without the need for empirical binary interaction parameters, as was required …

New Insights into the Mitigation of Asphaltene Deposition and the Utilization of Asphaltene Deposits
… Chain - Statistical Associating Fluid Theory (PC-SAFT). A shift in the asphaltene onset pressure (AOP) curve and a reduction in the amount of asphaltene precipitated was observed for four light oils from the Middle East. Results have shown that asphaltene precipitation can be eliminated by the …
