Due to its in situ and nondestructive nature, ground-penetrating radar (GPR) has recently been applied to the field investigation of plant roots. The discrepancy between the roots and surrounding soils creates a dielectric constant contrast, forming clear hyperbolic reflections on the GPR radargram. The intensity and shape of the reflecting signals from roots are substantially affected by the root...
Plant self-thinning power law is regarded as an essential regulation which plays an important role in determining population dynamics and community structure. However, little experimental and theoretical studies on the power law have been developed for shrub, and also little has been done from the perspective of below-ground plant parts to reveal the mechanisms underlying the self-thinning process...
Knowledge network embeddedness describes the external institutional arrangement of a firm's relationship with other firms to draw knowledge from external sources. Disruptive innovation has been a critical strategy to achieve indigenous technological innovations and catching-up in developing countries. The central tenet of our argument is that how well a disrupter performs is contingent upon the extent...
How did enterprise innovation capability convolutes with external environment in the context of economic transition? In this paper, a longitude study is operated, using the case of Sunyard, to show the rule as well as the mechanism underlying the coevolution process. On the one hand, this paper reveals how enterprise adapt to the environment to pursue resources for product innovation under multi-institutional...
Design and development of the management system software is just to meet the needs of domestic and international orienteering competition. The system is divided into management system before the game, the game and after the management system management system, which have greatly improved orienteering sports competition management level in our country. In the analysis of constructing the whole system...
With the help of the computer technology and the softwares of visual foxpro, microsoft access and spaa, I designed the automatic evaluation software for the recruit selection test of the high level athletes in Shandong Jiaotong University by myself so that it solved the difficulties which have been long time exsiting in the recruit selection test. The outcome are as follows: this testing system has...
Script-based automated regression testing is widely used in industry. In this work, we focus on failed tests in a real regression test project. The causes of 197 failed tests produced in automated testing are examined and categorized based on an analysis procedure presented. The result shows that incorrect scripts, oracle mismatches, test tool bugs and misconfigurations involved in testing contribute...
A roof-top scaled experimental wind turbine was simulated in FLUENT. Meshing technique for wind turbine blades was studied and a suitable mesh was achieved. The SST k-ω model was set to be the turbulence model in FLUENT. Detailed settings were studied to maintain a convergent and more accurate simulation. The simulation predicted the wind turbine power coefficient in different tip speed ratios. The...
Although the disruptive innovation (DI) theory of Christensen has nowadays been accepted by academics and practitioners as a powerful innovation strategy, many have only viewed it from a particular perspective such as market development that is not sufficient to judge confidently if an early stage DI case has a good chance to succeed. In this paper, we shall present an assessment framework that captures...
Open source software attracts more and more attentions in the world, motivation of individuals and firms participating such activities also raises interest. This study proposes the motivation framework, including individuals and firms, their intrinsic and extrinsic motives from economic, social and technological view tries to deep understand this phenomenon. This study summarizes that intrinsic motivations...
