PURPOSE Acute renal graft rejection can only be definitively diagnosed by renal biopsy. However, biopsies carry a risk of renal transplant injury and loss. Micro-CT is widely used in preclinical studies of small animals. Here, we propose micro-CT could noninvasively monitor and evaluate renal location and function in a mouse kidney transplant model. METHODS Orthotopic kidney transplantation w...

Charitable crowdfunding is a burgeoning online micro charity paradigm where fund seekers request micro donations from a large group of potential funders. Despite micro charities have gone digital for more than a decade, our knowledge on individuals’ donation behavior in online micro charities (e.g., charitable crowdfunding) remains limited. To fill this gap, this study develops a model that exp...

In this paper, a formal approach is taken to organize the body of knowledge about quality. The body of knowledge thus formalized is structured into: TOVE Quality Ontology, and the ISO 9003 Micro-Theory. The TOVE Quality Ontology represents a prototype formalization, researched from ISO 9000 and other quality management references, but independent of any one source. And the ISO 9003 Micro-Theory...

Develop a technique for the multi-scale modeling of cohesive interfaces to (1) obtain a better understanding of the micro-scale processes occurring during delamination and (2) use this knowledge to develop and quantify predictive models at the application scale. Methods The multi-scale scheme is shown in figure 3. At the macro-scale the cohesive zone (CZ) element formulation of Van den Bosch is...

A micro-mechanics damage model is proposed based on homogenization of penny-shaped cohesive micro-cracks (Barenblatt–Dugdale type) in a three dimensional representative volume element. By assuming that macro-hydrostatic stress state has dominant effect on permanent crack opening, a class of pressure sensitive yielding potentials and corresponding damage evolution laws have been derived. The mer...

Micro-grid is a kind of distributed low-voltage supply network by integrating various distributed powers, energy storage systems and controlled load. In micro-grid, distributed power can be divided into certain and stochastic power. The prediction on supply capacity of micro-grid focuses on electric energy production by stochastic power. The wind energy power is predicted in this paper by suppo...

There have been many domain-specific keyword extraction researches, but micro-blogoriented keyword extraction is just beginning. This paper researches into the keyword extraction from Chinese micro-blog. Taking the characteristics of micro-blog into account, such as short, topic divergence, etc., we propose a Chinese micro-blog keyword extraction method based on the combination of multi feature...

In this paper, a hardware in the loop simulation (HIL) is presented. This application is purposed as the first step before a real implementation of a Generalized Predictive Control (GPC) on a micro-grid system located at the Military University Campus in Cajica, Colombia. The designed GPC, looks for keep the battery bank State of Charge (SOC) over the 70% and under the 90%, what ensures the bes...

In this study, electro-thermo-mechanical nonlinear vibration and instability of embedded piezoelectric micro-tube is carried out based on nonlocal theory and nonlinear Donnell's shell model. The smart micro-tube made of Poly-vinylidene fluoride (PVDF) is conveying an isentropic, incompressible fluid. The detailed parametric study is conducted, focusing on the remarkable effects of mean flow vel...

Waterwheels are the oldest types of hydraulic machines. These turbines are of relatively simple design, large diameter, low rotational speed and high torques. But applying them as micro hydros of high speed and small diameter is yet to be explored. A micro hydro waterwheel of one meter diameter was designed and manufactured at the Iranian  esearc†h Organization for Science and Technology (IROST...
