Most existing work on sensor networks concentrates finding efficient ways to forward data from the information source centers, and not much has been done collecting local generating report. This paper studies this issue by proposing techniques detect track a mobile target. We introduce concept of dynamic convoy tree-based collaboration, formalize it as multiple objective optimization problem which needs find tree sequence with high coverage low energy consumption. propose an optimal solution...
Additive manufacturing (AM), also known as 3D printing, is gaining wide acceptance in diverse industries for the of metallic components. The microstructure and properties components vary widely depending on printing process parameters, prediction causative variables that affect structure, defects helpful their control. Since models are most useful when they can correctly predict experimental observations, we focus available mechanistic AM have been adequately validated. Specifically,...
In situ time-resolved x-ray diffraction (TRXRD) experiments were used to track the evolution of α→β→L→β→α/α′ phase transformation sequence during gas tungsten arc welding Ti–6Al–4V. Synchrotron radiation was employed for in measurements both fusion zone (FZ) and heat-affected (HAZ) weld, providing information about rates under rapid heating cooling conditions. The TRXRD data coupled with results computational thermodynamic predictions equilibria, numerical modeling weld temperatures. show...
The evolution of temperature and velocity fields during gas tungsten arc spot welding AISI 1005 steel was studied using a transient numerical model. calculated geometry the weld fusion zone heat affected thermal cycles were in good agreement with corresponding experimental results. Dimensional analysis used to understand importance transfer by conduction convection at various stages pool role driving forces for liquid pool. cooling rates are found be almost independent position between 1073...
We report an in-situ neutron diffraction study of a large format pouch battery cell. The succession Li-Graphite intercalation phases was fully captured under 1C charge-discharge condition (i.e., charge to full capacity in 1 hour). However, the lithiation and dilithiation pathways are distinctively different and, unlike slowing charging experiments with which phase diagram established, no LiC24 found during at rate. Approximately 75 mol. % graphite converts LiC6 lattice dilation as 4%...
Magnesium hydride (MgH2) exhibits long-term stability and has recently been developed as a safe alternative to store hydrogen in the solid state, due its high capacity of 7.6 wt% H2 low cost compared other metal hydrides. However, activation energy poor kinetics MgH2 lead inadequate storage properties, resulting efficiency. Nano-catalysis is deemed be most effective strategy improving performance materials. In this work, robust efficient architectures carbon-wrapped transition (Co/C, Ni/C)...
Abstract Welding is a major manufacturing process that joins two or more pieces of materials together through heating/mixing them followed by cooling/solidification. The goal welding to join meet service requirements at lowest costs. Advanced use scientific methods realize this goal. This paper views advanced as three step approach: (1) pre-design selects and joint design based on available processes (properties, capabilities, costs); (2) uses models predict the result from given set...
The temperature profiles, weld pool shape and size, the nature of solidified reinforcement surface during gas–metal arc (GMA) welding fillet joints were studied using a three-dimensional numerical heat transfer model. model solves energy conservation equation boundary fitted coordinate system. profile was calculated by minimizing total energy. Apart from direct transport arc, additional metal droplets modeled considering volumetric source. size fusion zone, finger penetration characteristic...
