Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
… potential sources of inoculum in the grapevine propagation process (including propagation material, the grafting process and nursery beds) that may result in infected young vines. Methodology for culturing and maintaining the fungus were investigated. The optimum temperature for growth of the …

Overlapping communities on social networks : a self-falsifiable hierarchical detection algorithm
… community detection based on an advanced label propagation process, which imitates the community formation process on social networks. Our algorithm is parameter-free and is able to reveal the hierarchical order of communities in the graph. The unique property of our solution scheme is …

Variations of zero forcing and power domination
<p>Zero forcing is a propagation process on a graph that turns white vertices into blue vertices. In this process, an initial set of vertices in a graph $G$ are chosen to be blue and all others are colored white, then a color-change rule is iteratively applied until all of $G$ becomes blue. A large …

Inflation and economic growth: a dynamic analysis of deficit finance
… growth path of real output? When all the dynamic propagations of the initial impact of ICF spendings are accounted for and it is shown that the resulting public capital formation is simply a substitute for otherwise available private capital formation, then the policy of ICF would have failed the …

Channel Modelling of Blood Capillary-based Molecular Communication
… of information through the transmission, propagation, and reception of molecules. Blood capillaries, extensively distributed in the human body and mutually connected with tissues, are potentially applied to MC, which is the major motivation of this thesis. The focus of this PhD thesis is …

Time Reversed Acoustics and applications to earthquake location and salt dome flank imaging
… and image subsurface structures. The back-propagation process of the TRA experiment can be divided into the acausal and causal time domain. Studying the acausal process of TRA enables us to locate the source, such as an earthquake, inside a medium. The causal domain allows us to create a …

A Novel Shape Memory Behavior of Single-crystalline Metal Nanowires
… the transformation. The lattice reorientation process is also temperature-dependent because thermal energy facilitates the overcoming of the energy barrier for the transformation. Therefore, nanowires show either pseudoelasticity or shape memory effect depending on whether the transformation is …

Power System Dynamic Control and Performance Improvement Based on Reinforcement Learning
… for our control reference signal) without back-propagation process for gradient update using a simultaneous perturbation stochastic approximation approach comparing to many other RL algorithms, thus it achieves a much faster and more robust learning convergence. It is introduced and implemented …

Edge Fracture Prediction Of Dual Phase Steels With Consideration Of Microstructures
… Phase DP780 and DP980. The HE test includes two processing steps: hole punching and hole expanding. The punching process creates holes of various sheared edge morphologies, which are the input to the hole expanding process, along with the intrinsic property of material, produce a joint effect on …

Vision and Language: Information Integration and Transformation
… during inference time. We design the feedback propagation process for image captioning models during inference time to show that information can be transferred between images and different languages to achieve benefits in text generation without an additional training process. By providing …

Information Propagation Algorithms for Consensus Formation in Decentralized Multi-Agent Systems
… of theory and experimentation. Information propagation process and an information propagation algorithm are derived by unifying the general structure of multiple existing solutions to the decentralized consensus problem. They are then used to define two classes of algorithms that spread …

Anti-plane Shear of Cylinders and Layered Systems: Cohesive Fracture and Instability
… fields capture the entire defect evolution process from incipient growth through complete failure. The anti-plane shear separation/slip process is assumed to be modeled by Needleman-type traction-separation relations (e.g., bilinear, Xu-Needleman, frictional) characterized by a shear …

Transient Phenomena in Annular Combustors
… configurations, which is the burner-to-burner propagation process, known as “light-round”. For stable conditions, a wide range of mixture velocities and equivalence ratios were tested, along with two spark locations (close to a single burner and in the middle of the combustion chamber). Two …
