Because triiodobenzoic acid increases pod number, albeit variably, in soybean (Glycine max), we tested other auxin-transport inhibitors. Morphactins, especially methylchlorflurenol (MCF), were found to be very active (optimal concentration 10 micromolar) when sprayed onto the foliage. Applications at 1 week after the start of flowering were most effective, producing a 40% increase in pod number...

This thesis involves the modeling of self-sustained oscillations in the flow past a rectangular cavity. The emphasis is on developing low-dimensional models that are suitable for analysis using tools from dynamical systems and control theory. Two-dimensional direct numerical simulations are performed, and indicate the presence of a “wake mode,” which has been observed previously in experiments,...

We propose an online adaptive local-global POD-DEIM model reduction method for flows in heterogeneous porous media. The main idea of the proposed method is to use local online indicators to decide on the global update, which is performed via reduced cost local multiscale basis functions. This unique local-global online combination allows (1) developing local indicators that are used for both lo...

This paper presents a design approach for a magnetic sensor module to detect mover position using the proper orthogonal decomposition-dynamic mode decomposition (POD-DMD)-based nonlinear parametric model order reduction (PMOR). The parameterization of the sensor module is achieved by using the multipolar moment matching method. Several geometric variables of the sensor module are considered whi...

An efficient, stability-preserving model reduction technique for non-linear initial boundary value problems (IBVPs) whose solutions exhibit inherently non-linear dynamics such as metastability and periodic regimes (limit cycles) is developed. The approach is based on the “continuous” Galerkin projection approach, in which the continuous governing equations are projected onto the reduced basis m...

We present our study on flows past porous obstacles, which exhibit complex nonlinear dynamics. Regions in the near-wake host multiple modes of hydrodynamic instabilities, interact with bleed flow from trailing edge. As a result, developing shear layers weaken and wakes protract. The dynamics are largely altered by configuration patches even when plan porosities similar. describe wake turbulence...

Understanding flow structures in urban areas is widely recognized as a challenging concern due to its effect on development, air quality, and pollutant dispersion. In this study, state-of-the-art data-driven methods for modal analysis of simplified flows are used study the dominant processes these environments. Higher order dynamic mode decomposition (HODMD), highly-efficient method analyze tur...

BACKGROUND Clinical data indicate that laparoscopic surgery reduces postoperative inflammatory response and benefits patient recovery. Little is known about the mechanisms involved in reduced systemic and local inflammation and the contribution of reduced trauma to the abdominal wall and the parietal peritoneum. METHODS Included were 61 patients, who underwent elective colorectal resection wi...

The world is changing rapidly. Yet a common assumption is that cars, buses and taxis will remain the dominant local passenger transport modes in the coming decades. This concept paper draws on literature sources and on discussions with industry stakeholders to look anew at the local passenger transport sector in the light of broader societal trends to suggest an alternative future, and to offer...

Computational reliability assessment in mechanized tunneling requires realistic numerical models accounting for the uncertainty of geotechnical and tunneling process parameters. For real-time prognoses, surrogate models are in general inevitable to substitute expensive complex numerical simulations. In this paper, different strategies for surrogate modeling in mechanized tunneling simulations a...
