Photoacoustic imaging with a synthetic aperture focusing technique (SAFT) is an effective method to improve the lateral resolution for out-of-focus regions in scanning microscopy systems, which commonly require a decent motorized scanning stage for a lateral scan of a transducer to obtain a cross-sectional image. In this study, we propose and test a photoacoustic imaging system with a scanning ...
Unstable networks such as wireless mobile ad hoc networks (MANETs) are radically different from traditional fixed networks like the Internet. The success of these emerging networks is determined by the performance of the communication layers and the transport layer. For the latter, many protocols have been proposed based on adaptations of TCP for such unstable networks. In this paper, we claim ...
The accuracy of several theories for the thermodynamic properties of the Yukawa hard-sphere chain fluid are studied. In particular, we consider the polymer mean spherical approximation (PMSA), the dimer version of thermodynamic perturbation theory (TPTD), and the statistical associating fluid theory for potentials of variable attractive range (SAFT-VR). Since the original version of SAFT-VR for...
Molecular genetic analyses in Arabidopsis disclosed a genetic pathway whereby flowering is induced by the photoperiod. This cascade is examined here within the time course of floral transition in the long-day (LD) plant Sinapis alba induced by a single photoperiodic cycle. In addition to previously available sequences, the cloning of CONSTANS (SaCO) and FLOWERING LOCUS T (SaFT) homologues allow...
Kurzfassung. Die Synthetic Aperture Focusing Technique (SAFT) ist ein Verfahren zur Verarbeitung von HF-Bildern, die an unterschiedlichen Prüfkopfpositionen aufgenommen wurden. Es wird in der zerstörungsfreien Werkstoffprüfung genutzt, um eine Abbildung von Materialfehlern innerhalb des Gebietes zu erstellen, auf das die Rekonstruktion angewandt wird. Die nach Abschluss der SAFT-Rekonstruktion ...
در این کار، معادله حالت ساده شده saft مشابه با معادله حالت ساده شده pc-saft برای مدل سازی تعادل فازی بخار- مایع سیستم هایی شامل مواد غیرتجمعی- غیرتجمعی، تجمعی- غیرتجمعی و تجمعی- تجمعی، بکار رفته است. در این کار، از معادله حالت ساده شده saft برای بررسی تعادل فازی بخار- مایع سیستم های دوجزئی متان- پروپان، متانول- پنتان و آب- متانول استفاده شده است. دراین مقاله، در معادله حالت ساده شده saft از تاب...
The SAFT-VR equation of state is extended to treat heteronuclear chain fluids, focusing, in particular, on symmetric and asymmetric diblock chains. The chain molecules studied are composed of segments of different size and/or energy of interaction. Both symmetric and asymmetric systems are considered. The theoretical predictions are compared with isothermal– isobaric and Gibbs ensemble Monte Ca...
Synthetic aperture focusing technique (SAFT) has been used in non-destructive testing mainly in its simplest form that mimics acoustic lenses used for focusing ultrasonic beams at a point of a solid object or structure. This paper presents a review of SAFT algorithms applied for post-processing of ultrasonic data acquired in non-destructive inspection of metals. The performance of SAFT in terms...
The statistical associating fluid theory for potentials of variable range plus dipole (SAFT-VR+D) is extended to study associating dipolar fluids. In the SAFT-VR+D approach dipolar interactions are taken into account through the use of the generalized mean spherical approximation to describe a reference fluid of dipolar square-well segments. This enables the effect of the dipolar interactions o...
