Anaerobic co-digestion (AcoD) is a widely employed technique to produce biogas from simultaneous digestion of various biomasses. However, the selection optimal proportions substrates in mixtures presents challenge. This research used mixture design investigate interactions between liquid fraction piglet manure (PM), cow (CWM), and starch wastewater (SWW). A modified Gompertz model was identify ...

To address the balance problem between indexes within performance evaluation of bridge systems, this paper develops an age- and condition-based variable weight model (ACVWM). First, limitations existing models used for multi-layer weighted sum method, i.e., constant (CWM) (CVWM), are presented through case studies, indicating that variation is insufficient to characterize deterioration law comp...

Abstract Predicting community‐level trait indices, such as community‐weighted mean or functional dispersion, in space time, is crucial, they are markers of ecosystem functions, proxies for services, and now integral part conservation planning. On one hand, since members a species share similar traits, natural way to model distributions function the environment first (i.e. with distribution mode...

Trait-based approaches have been widely applied to investigate how community dynamics respond to environmental gradients. In this study, we applied a series of maximum entropy (maxent) models incorporating functional traits to unravel the processes governing macrophyte community structure along water depth gradient in a freshwater lake. We sampled 42 plots and 1513 individual plants, and measur...

The paper presents the dynamic compound wavelet method (dCWM) for modeling the time evolution of multiscale and/or multiphysics systems via an "active" coupling of different simulation methods applied at their characteristic spatial and temporal scales. Key to this "predictive" approach is the dynamic updating of information from the different methods in order to adaptively and accurately captu...

Context: Spectroscopic imaging can be helpful to identify metabolite changes in a normal appearing brain parenchyma after MR imaging in patients with lung cancer. Aims: To detect metabolic changes in the cerebellar and cerebral normal appearing white matter with single-voxel H-MR spectroscopy (MRS) in patients with lung cancer. Methods and material: MRS was performed in the Cerebellar White Mat...

This paper focuses on the binary analysis of the center-weighted median (CWM) filters. This subclass of nonlinear stack filters is based on minimal positive Boolean functions (PBFs), the complexity of which depends on two parameters only, such as a window size and a weight of the central sample. It can be easily seen that the complexity of PBFs corresponding with CWMs increases with the increas...

BACKGROUND There are several vacuum mixing systems on the market which are arbitrarily used with various bone cements in clinical work. Hardly any studies have been done on the performance and handling of these systems in combination with different cement brands. MATERIAL AND METHODS We therefore tested 6 vacuum mixing systems (Palamix, Summit, Cemvac, Optivac, Vacumix, MixOR) in combination ...
